During his travels in time and space, [[the Doctor]] employed many different aliases; sometimes only briefly and sometimes on an ongoing basis. Owning to his refusal to tell all but a few people his real name, he often had names bestowed upon him by others, often to his chagrin.
{{doctor more}}
Throughout their travels in time and space, [[the Doctor]] took on and was called by a number of '''different [[alias]]es, titles and [[name]]s'''. Some were fleeting, while others, like '''John Smith''', were used by almost all of their [[incarnation]]s, with [[#Commonly used aliases|some variations]]. The Doctor told very few people their original name, instead asking others to simply call them '''the Doctor'''. By many accounts, the Doctor considered this title to be their real name. ([[TV]]: {{cs|The Name of the Doctor (TV story)}} et al.) It was their chosen [[identity]], and a [[The Doctor (title)|promise to the universe]]. ([[TV]]: {{cs|The Sound of Drums (TV story)}}, {{cs|The Beast Below (TV story)}}, {{cs|The Day of the Doctor (TV story)}})


==The mystery of the Doctor's real name==
In other accounts, however, the Doctor's "true name" was the one which was [[The Question|hidden]], a guarded secret the Doctor kept from almost everyone. ([[TV]]: {{cs|The Girl in the Fireplace (TV story)}}, {{cs|The Shakespeare Code (TV story)}}, {{cs|The Fires of Pompeii (TV story)}}, {{cs|The Time of the Doctor (TV story)}}) Most names the Doctor kept were a matter of convenience, and they were prone to take on whichever name would help them blend in best, or stand out more, depending on the situation. Some [[companion]]s felt this was not the Doctor's strongest suit, however. ([[AUDIO]]: {{cs|What Just Happened? (audio story)}} et al.)
===Ubiquity of the title===


== The Doctor's real name ==
Most accounts treated the Doctor's true name as a complete mystery. [[Bill Potts]], his student, asserted that "nobody [knew] the Doctor's real name", although [[Missy]] claimed that she was an exception to this given that she "grew up with him". ([[TV]]: {{cs|World Enough and Time (TV story)}}) One account even implied that their given name was [[Elective Semantectomy|ceremoniously withdrawn and stricken]] by their Cousins as punishment for a disgrace the Doctor had brought upon [[House of Lungbarrow|their House]]. ([[PROSE]]: {{cs|Lungbarrow (novel)}}) By another account, it had "broke" into as many pieces as there were syllables it took to say, and he gifted a piece to some of those he met on his travels. ([[PROSE]]: {{cs|Return of the Living Dad (novel)}}) However, the Doctor's true name did appear in [[secret]] [[file]]s created by the [[High Court of the Time Lords|High Court]] of the [[Time Lords]], containing a transcript of [[the Doctor's trial (The War Games)|the Doctor's trial]], where it was [[Old High Gallifreyan|spelled]] as "[[∂³Σx²]]". ([[PROSE]]: {{cs|The Trial of Doctor Who (short story)}}) While wandering in the Doctor's TARDIS, Clara Oswald read [[The History of the Time War|a history of the Time War]] which apparently told her the Doctor's name, causing her to remark "So that's who." ([[TV]]: {{cs|Journey to the Centre of the TARDIS (TV story)}})


Even when put on trial by the [[Time Lord]]s, they were only referred to as "the Doctor", ([[TV]]: {{cs|The War Games (TV story)}}) although [[the Valeyard]], a culmination of the Doctor's darker side who prosecuted the second trial, acknowledged that this was an alias. ([[TV]]: {{cs|The Mysterious Planet (TV story)}}) When the [[Fifth Doctor]] was officially inducted as [[Lord President]], he declared that it was "out of the question" for him to be introduced by his true name, stating that he would accept being introduced as "Lord President Doctor". ([[AUDIO]]: {{cs|Time in Office (audio story)}}) Even those who had known them in childhood addressed them only as "the Doctor", such as [[the Master]], ([[TV]]: {{cs|Death in Heaven (TV story)}}) and [[the Rani]]. ([[COMIC]]: {{cs|Weapons of Past Destruction (comic story)}})
[[Image:Drcallingcard.jpg|thumb|200px|[[Seventh Doctor|The Doctor]]'s calling card. [[DW]]:''[[Remembrance of the Daleks]]'']]
"The Doctor" was not, in fact, a name, but a title. His given name was not generally known (see below), and as such the very title "the Doctor" was an alias. It has been implied his given name was ceremoniously withdrawn and stricken by his Cousins, as punishment for a disgrace he visited upon [[House of Lungbarrow|his House]]. ([[NA]]: ''[[Lungbarrow]]'') When asked about [[Sixth Doctor|the Doctor]]'s name, his [[companion]] [[Peri Brown]] once said she'd been told she couldn't pronounce it. ([[BBCR]]: ''[[Slipback]]'') Even when he was twice put on trial by his own people, the Time Lords, he was only ever referred to during these events as "the Doctor" ([[DW]]: ''[[The War Games]]''), although [[The Valeyard]], who prosecuted the second trial (and who, himself, was a future manifestation of the Doctor), acknowledged that it was an alias. ([[DW]]: ''[[Trial of a Time Lord]]'') However, as the Doctor chose that "name" as part of Gallifreyan custom ([[DW]]: ''[[The Sound of Drums]]''), its use in an official capacity is not unexpected.


The Doctor was able to keep his true name hidden despite numerous "mind-probe" attempts, both voluntary ([[DW]]: ''[[The Girl in the Fireplace]]'') and involuntary ([[DW]]: ''[[The Shakespeare Code]]'').
According to one account, during their [[First Doctor|first incarnation]], the Doctor adopted this name in dealing with [[human]] colonists on the [[planet]] [[Iwa]] at the same time that his [[Susan Foreman|granddaughter]] adopted the name "Susan". ([[PROSE]]: {{cs|Frayed (novel)}}) Other accounts implied that the Doctor's title had been chosen as a Gallifreyan custom, ([[TV]]: {{cs|The Sound of Drums (TV story)}}) and that he had been using it before he left Gallifrey. ([[TV]]: {{cs|The Name of the Doctor (TV story)}}, {{cs|World Enough and Time (TV story)}})


===Individuals who knew (or might know) his true name===
The Doctor's real name has been said to be difficult to pronounce, for [[human]]s at least, ([[PROSE]]: {{cs|Doctor Who and the Auton Invasion (novelisation)}}, [[AUDIO]]: {{cs|Slipback (audio story)}}) and certainly for adults, ([[TV]]: {{cs|Twice Upon a Time (TV story)}}) possessing thirty eight syllables. ([[PROSE]]: {{cs|SLEEPY (novel)}}, {{cs|Return of the Living Dad (novel)}}) The [[First Doctor]] once told an interrogator he "wouldn't be able to pronounce the first syllable of [his name]." ([[PROSE]]: {{cs|Salvation (novel)}}) His [[Seventh Doctor|seventh incarnation]] likewise told one of his captors that he "doubt[ed] [they]'d be able to pronounce the name [he] was originally given." ([[PROSE]]: {{cs|Illegal Alien (novel)}}) When asked about the Doctor's name, [[Peri Brown]] once said that the Doctor had told her she would find it unpronounceable. ([[AUDIO]]: {{cs|Slipback (audio story)}})


[[The Master]] and the Doctor had known each other since their [[Prydon Academy]] days, and by one account even earlier ([[BFA]]: ''[[Master (audio story)|Master]]''), but it is not known for certain whether he ever knew the Doctor's true name, although he was well aware that "the Doctor" was an alias. ([[DW]]: ''[[The Sound of Drums]]'') Another classmate of the Doctor's, [[Drax]], may have known his real name, but instead referred to the Doctor by the nickname "Thete", short for Theta Sigma. ([[DW]]: ''[[The Armageddon Factor]]''; ''[[The Happiness Patrol]]'')
However, the [[First Minister of Chance]] once answered similarly when asked what his real name was, only to play it off as a joke and explain that "the Minister" ''was'' his real name, with this simply being how Time Lord names worked. ([[WC]]: {{cs|Death Comes to Time (webcast)}}) The [[Fifteenth Doctor]] similarly suggested that all Time Lord names were [[Vocational name|titles]], and that the original name he had discarded for "the Doctor" was already a "the" title; he prepared to tell it to [[Ruby Sunday]] as they stepped out of the [[TARDIS control room]], getting at least as far as "the". ([[TV]]: {{cs|Space Babies (TV story)}})


[[Madame de Pompadour]] recognized it as an alias when she was briefly connected to the Doctor's mind ([[DW]]: ''[[The Girl in the Fireplace]]''), stating "Doctor...Doctor who? It's more than just a secret, isn't it?". Whether or not Madame de Pompadour actually learned his name this way remains undisclosed. She was able to see into his mind and into his past, although it was established that if mind-reading was done in this way, memories could be closed off at will. That said, the Doctor was not aware that she was reading his mind at the time.
Moments before his [[regeneration]], the [[Twelfth Doctor]] stated his belief that "[[child]]ren [could] hear [his name]", but only when "their hearts [were] in the right place, and the stars [were] too", adding: "but nobody else… nobody else… ''ever''", emphasising to [[Thirteenth Doctor|his uncreated next self]] that she "mustn't ever tell anyone [her] name". ([[TV]]: {{cs|Twice Upon a Time (TV story)}})


[[River Song]], who when [[Tenth Doctor|the Doctor]] first encountered her claimed to have known him at some point in his future, is one of the only individuals confirmed to know his true name. In order to win the Doctor's trust, and prove her "credentials", she was seen to whisper the name into his ear. The Doctor seemed particularly shocked at this, later saying to her "there is only one reason I would ever tell anyone my name, only one time I could."([[DW]]: ''[[Forest of the Dead]]'')
The Doctor kept their true name hidden despite numerous "mind-probe" attempts and the effect of a [[Truth Field|truth field]]. ([[TV]]: {{cs|The Girl in the Fireplace (TV story)}}, {{cs|The Time of the Doctor (TV story)}}) The [[Carrionite]] [[Lilith (The Shakespeare Code)|Lilith]], unable to discover the [[Tenth Doctor]]'s true name even with the "[[witchcraft]]" used by her kind, remarked that "there [was] no name," and that the Doctor was hiding it in despair. ([[TV]]: {{cs|The Shakespeare Code (TV story)}}) The psychically-gifted [[Evelina (The Fires of Pompeii)|Evelina]], who attempted to foretell the Doctor's future, remarked that his "true name" was "hidden" from her. ([[TV]]: {{cs|The Fires of Pompeii (TV story)}})


''She whispered the Doctor's name for a duration of roughly two seconds, suggesting the name may only be a few syllables long (assuming she uttered a complete name). The significance of the Doctor's statement afterwards is open to a number of possible interpretations.'' As [[Steven Moffat]] made a point of mentioning the Doctor's name (and its secrecy), it is possible he will make some sort of a point of it in the upcoming [[Series 5]]. Indeed, he has stated in the past that he always felt the Doctor's name was never revealed only because it must have been some "terrible secret".
By one account, in his youth, the Doctor had outright removed his name from time, all but he and the Master forgetting his birth name. ([[AUDIO]]: {{cs|Blood of the Time Lords (audio story)}})


At least one other person, [[Eighth Doctor|the Doctor]]'s [[companion]] [[Samantha Jones]], was also told his real name ([[EDA]]: ''[[Unnatural History]]'', [[EDA]]: ''[[Vanderdeken's Children]]''). Whether the Doctor's statement to River Song applies to her as well is unclear.
=== Significance ===
By one account, names held mystic importance in Time Lord society, meaning that all Time Lords kept their true names as closely-guarded secrets. In this sense, the Doctor's name was not any more or less significant than any other Time Lord's. ([[PROSE]]: {{cs|Doctor Who and the Auton Invasion (novelisation)}})


===Attempts to discover his true name===
The [[Eleventh Doctor]] told [[Clara Oswald]] that his original name was not important since he specifically chose the title of "Doctor" to take its place, saying it was "like a [[promise]] [one made]." ([[TV]]: {{cs|The Name of the Doctor (TV story)}}) This [[vow|promise]] was; ''"Never cruel or cowardly. Never give up, never give in."'' ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) Even Clara considered "the Doctor" to be his true name and the only one that mattered. ([[TV]]: {{cs|The Time of the Doctor (TV story)}}) Despite their hatred of the War Doctor's actions, ([[TV]]: {{cs|The Name of the Doctor (TV story)}}) both the tenth and eleventh incarnations admitted "[he] was the Doctor more than [any of them]." ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) When Clara was forced to take on his role for him, the [[Twelfth Doctor]] told her that "goodness has nothing to do with [being a Doctor]". ([[TV]]: {{cs|Flatline (TV story)}})


The [[Carrionite]] [[Lilith]], unable to discover [[Tenth Doctor|the Doctor]]'s true name even with the "[[witchcraft]]" used by her kind, remarked, "There is no name. Why would a man hide his title in such despair?" ([[DW]]: ''[[The Shakespeare Code]]'') The psychically-gifted [[Evelina]], who attempted to foretell the Doctor's future, remarked that his "true name" was in fact "hidden". ([[DW]]: ''[[The Fires of Pompeii]]'')
The Doctor considered abandoning his name if he felt he had to do something highly immoral. ([[TV]]: {{cs|The Beast Below (TV story)}}, {{cs|Face the Raven (TV story)}}) The [[War Doctor]] rejected the name to fight in the Time War, ([[TV]]: {{cs|The Night of the Doctor (TV story)}}) but proudly called himself the Doctor once he was given the chance to end the conflict without killing the Time Lords. ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) During his final day, the Twelfth Doctor stated being "the Doctor" was being kind, even if it meant pulling a self-sacrifice to bring others a small amount of extra time to live. ([[TV]]: {{cs|The Doctor Falls (TV story)}}) The [[Thirteenth Doctor]] said that a "bit of adrenaline, dash of outrage and a hint of panic" helped her to remember she was the Doctor. ([[TV]]: {{cs|The Woman Who Fell to Earth (TV story)}})


===Significance of the title===
{{Simm|c}} knew of this and implied that the Doctor's title had been chosen because it meant "the man who makes people better", although he found the choice "sanctimonious" for someone who ended millions of lives and ruined many others. ([[TV]]: {{cs|The Sound of Drums (TV story)}}) [[River Song]] was aware of this contradiction in the Doctor's behaviour: she said that the Doctor was the first to have this title and that the rest of the universe later adopted it, usually to mean "healer" or "wise man". However, she added that, in some parts of the universe, such as in the [[Gamma Forests]], it eventually came to mean "mighty warrior". ([[TV]]: {{cs|A Good Man Goes to War (TV story)}})


Far from being a random title, or one intended to inflate his credentials, the Doctor did, indeed, possess at least one doctorate ([[DW]]: ''[[The Armageddon Factor]]''; ''[[The Mysterious Planet]]'') On other occasions he described himself as a "Doctor of many things", or, indeed, "everything" ([[DW]]: ''[[Utopia (TV story)|Utopia]]''). Exactly what his doctorate(s) were for remain a mystery, although on several occasions the Doctor stated he was not a medical doctor (although that didn't stop his tenth incarnation from sporting a stethoscope on occasion).
According to [[Dorium Maldovar]], [[the Silence]] had a particular interest in the Doctor's name. He explained that if the Doctor lived long enough, "on the fields of [[Trenzalore]], at the fall of the Eleventh, [when] no creature could speak falsely or fail to answer", a question that must never be answered would be asked: "[[The Question|Doctor Who?]]". The Silence wanted to stop the Doctor from revealing his true name. ([[TV]]: {{cs|The Wedding of River Song (TV story)}})


==List of aliases==
The Doctor was at a later time forced to go to Trenzalore to rescue his friends from the [[Great Intelligence]], which sought to gain access to the Doctor's tomb. The tomb, which was a future version of his own dying TARDIS, would open only to the Doctor's real name. The Intelligence threatened to kill [[Clara Oswald]] and the [[Paternoster Gang]] if he did not speak his name and open the tomb; the situation was resolved when the data ghost of [[River Song]] was able to silently transmit his name to the TARDIS, thus opening the door for the Great Intelligence. ([[TV]]: {{cs|The Name of the Doctor (TV story)}})


During his life, numerous names were either used by, or bestowed upon the Time Lord most widely known as the Doctor.
The Doctor's real name became important during the [[Siege of Trenzalore]], as it was the signal chosen by the Time Lords to come back to the universe, broadcasting the question "Doctor Who?" through a [[Time Field|crack in reality]], simultaneously broadcasting a [[Truth Field]] so that they could be sure that it was truly the Doctor responding to them. Despite this, when the Doctor was facing death, Clara told the Time Lords through the Crack that the only name of his that mattered was "the Doctor" and everything he stood for under that name, prompting them to give the Doctor a new regeneration cycle at the cost of closing the crack. ([[TV]]: {{cs|The Time of the Doctor (TV story)}})


===Major names and aliases===
After meeting his [[Twelfth Doctor|twelfth incarnation]], the [[First Doctor]] was confronted by the mysterious [[Testimony Foundation]], who claimed that the Doctor was the "Doctor of War". Although the First Doctor initially feared this interpretation of his future, after witnessing the Twelfth Doctor's efforts to save Captain [[Archibald Hamish Lethbridge-Stewart]], he came to conclude that the "Doctor of War" was not a man who revelled in war, but a man who sought the moments of peace that existed amid open warfare, and who would always try to find another way to end war, and to find resolution, rather than resorting to bloodshed. ([[TV]]: {{cs|Twice Upon a Time (TV story)}})


====The Doctor====
=== Ubiquity of the title ===
The Doctor did possess at least one doctorate. ([[TV]]: {{cs|The Moonbase (TV story)}}, {{cs|The Armageddon Factor (TV story)}}, {{cs|The Mysterious Planet (TV story)}}) They sometimes described themselves as a "doctor of many things" ([[TV]]: {{cs|Four to Doomsday (TV story)}}) or of "everything", ([[TV]]: {{cs|Spearhead from Space (TV story)}}, {{cs|Utopia (TV story)}}) as well as "a scientist, an engineer, builder of things". ([[TV]]: {{cs|The Aztecs (TV story)}}) However, their knowledge was limited to anything prior to the [[Rassilon Era]]. ([[TV]]: {{cs|Utopia (TV story)}}) The [[Eleventh Doctor]] claimed that one of his doctorates was in [[cheesemaking]], ([[TV]]: {{cs|The God Complex (TV story)}}) but only the "stinky, blue kind". ([[PROSE]]: {{cs|Shroud of Sorrow (novel)}})


As noted above, '''The Doctor''' itself was an alias, despite it being the name by which the Time Lord was most widely known. As per Gallifreyan custom, he chose this alias himself ([[DW]]:''[[The Sound of Drums]]''). On at least one occasion, a [[Human]] knew this name without the Doctor even saying it out loud. ([[NA]]: ''[[Cat's Cradle: Warhead]]'') His other aliases often included the title "Doctor". He implied to Peri that his given name also began with such a title ([[DW]]: ''[[The Trial of a Time Lord]]'': ''[[The Mysterious Planet]]''). [[Drax]], a fellow Time Lord, indicated that the Doctor did indeed possess a doctorate (although in what is not indicated) ([[DW]]: ''[[The Armageddon Factor]]''). According to one account, during his [[First Doctor|first incarnation]], the Doctor adopted this name for the benefit of [[Human]] colonists on the [[planet]] [[Iwa]] at the same that his [[Susan Foreman|grand-daughter]] adopted the name "Susan". ([[TN]]: ''[[Frayed]]'')
On several occasions, the Doctor claimed they were not a medical doctor. ([[TV]]: {{cs|An Unearthly Child (TV story)|namedep=The Forest of Fear (3)}}, {{cs|Marco Polo (TV story)|namedep=Mighty Kublai Khan (6)}}) Though by their [[second incarnation]], he had studied medicine in the [[19th century]], ([[TV]]: {{cs|The Moonbase (TV story)}}) although Clara recalled the Doctor telling her that he graduated in the wrong century. ([[TV]]: {{cs|Death in Heaven (TV story)}}) The Eleventh Doctor described himself as a medical doctor. ([[TV]]: {{cs|The God Complex (TV story)}}) The [[Seventh Doctor|seventh]], [[Eleventh Doctor|eleventh]] and [[twelfth incarnation]]s displayed some medical knowledge, being able to help with minor injuries ([[TV]]: {{cs|Remembrance of the Daleks (TV story)}}, {{cs|The Vampires of Venice (TV story)}}) and tell if a person was vitamin deficient. ([[TV]]: {{cs|Thin Ice (TV story)}}) The [[Ninth Doctor]] could also diagnose patients in a hospital ward, quickly deducing they all shared the injuries of a scar on the back of their hands, collapsed chest cavities, crushed rib cages and gas masks fused into the flesh on their faces, ([[TV]]: {{cs|The Empty Child (TV story)}}) and displayed extensive knowledge on [[nanogene]]s, such as their ability to repair organic matter and restore life as a mere "quirk of matter". ([[TV]]: {{cs|The Doctor Dances (TV story)}}) The [[Tenth Doctor]] in particular proved a proficient medic, performing life-saving surgery on [[Laszlo]], sustaining him as a Human-Pig hybrid, able to live as long as a human again. ([[TV]]: {{cs|Evolution of the Daleks (TV story)}})


====Theta Sigma====
When asked by [[Mabli]] if her doctorate was in medicine, the [[Thirteenth Doctor]] described herself as having a doctorate in "medicine, science, engineering, candyfloss, Lego, philosophy, music, problems, people, [and] hope." ([[TV]]: {{cs|The Tsuranga Conundrum (TV story)}})


'''Theta Sigma''' (ΘΣ), informally '''"Thete"''', was a nickname used by the Doctor during his years at the [[Time Lord Academy]] on the [[planet]] [[Gallifrey]]. ([[DW]]: ''[[The Armageddon Factor]]'', ''[[The Happiness Patrol]]'', [[DWM]]: ''[[Flashback]]'') The name might also have been a codename used by some aspects of [[Time Lord]] government to refer to the Doctor. (''[[The Adventures of K-9]]'' series)  
=== Individuals with knowledge of the Doctor's name ===
[[Susan Foreman]] knew the Doctor's real name, and wrote it on the wrappings of a [[hypercube]] she sent to him after she had settled down on Earth. ([[PROSE]]: {{cs|Ghost of Christmas Past (short story)}})


:''Note - in the [[Wikipedia:Greek alphabet|Greek alphabet]], Sigma (Σ) slightly resembles the letter W turned on its side, and the Greek letter Theta (Θ) slightly resembles the letter H inside the letter O.''
[[Ace]] knew his true name's signature, written using three runes but able to be condensed into one. ([[PROSE]]: {{cs|Timewyrm: Revelation (novel)}}) The [[Seventh Doctor]], half-unconscious, once told two [[Caxtarid]]s his name, which they remarked as being "hard getting [...] on the front of an envelope." ([[PROSE]]: {{cs|Return of the Living Dad (novel)}})


====John Smith====
The [[Sixth Doctor]] told his dance instructor, [[Becky (Teach Yourself Ballroom Dancing)|Becky]], his name. ([[PROSE]]: {{cs|Teach Yourself Ballroom Dancing (short story)}})


'''John Smith''' was the alias the Doctor often used on [[Earth]] and around [[Human]]s when a "standard" name was often required or demanded. It was usually preceded by the title "Doctor", though not always - for example, when he worked undercover as a teacher at a school and as a patient in a hospital. ([[DW]]: ''[[School Reunion]]'', ''[[Smith and Jones]]'') The earliest known use of the name occurred during his [[Second Doctor|second incarnation]], and it may have been devised by his companion at the time, [[Jamie McCrimmon]] ([[DW]]: ''[[The Wheel in Space]]''). Later, he adopted it on a semi-regular basis during his [[Third Doctor|third incarnation]] while [[Exile on Earth|exiled on Earth]] when he served as unpaid scientific advisor to [[United Nations Intelligence Taskforce|UNIT]]. ([[DW]]: ''[[Spearhead from Space]]'', et al)  
The [[Eighth Doctor]] used his real name when he forged passes for himself and his [[companion]], [[Sam Jones]], on board the ''Cirrandaria'' in 3123. He used this name when speaking to a guard, Sam finding it quite alien and virtually unpronounceable. ([[PROSE]]: {{cs|Vanderdeken's Children (novel)}})


As "John Smith" is considered a very generic name in some [[Earth]] cultures, the Doctor's use of the alias was occasionally treated with skepticism by others ([[DW]]: ''[[Midnight]]'').
When the [[Tenth Doctor]] first encountered her, [[River Song]] claimed to have known him at some point in his future, ([[TV]]: {{cs|Silence in the Library (TV story)}}) and, to prove her "credentials", she whispered his name in his ear, and apologised for having to do so. The Doctor was shocked at this, as "there [was] only one reason [he] would ever tell anyone [his] name, [and] only one time [he] could." ([[TV]]: {{cs|Forest of the Dead (TV story)}}) River indicated to [[Clara Oswald]] that she "made" the Doctor tell her his name and that "it took a lot of effort". ([[TV]]: {{cs|The Name of the Doctor (TV story)}})


At one point in his life, the Doctor temporarily changed himself into a human who used the name John Smith. There are conflicting reports as to whether this occurred [[John Smith (novel)|in his seventh incarnation]] ([[NA]]: ''[[Human Nature (novel)|Human Nature]]''), or [[John Smith (television)|in his tenth]] ([[DW]]: ''[[Human Nature (TV story)|Human Nature]]''/''[[The Family of Blood]]''). Due to the uncertain canoncity of the New Adventures novels, it is more likely the latter.
Near the end of his life, despite believing there was no one left in the universe who knew it, the Tenth Doctor encountered members of an unidentified pan-dimensional race that knew his real name. ([[AUDIO]]: {{cs|The Last Voyage (audio story)}})


=====Known uses of "John Smith"=====
While separated from the [[Eleventh Doctor]], [[Clara Oswald]] read his name in ''[[The History of the Time War]]''. Though [[Alternate timeline (Journey to the Centre of the TARDIS)|that timeline]] was aborted, leaving her with no memory of it, ([[TV]]: {{cs|Journey to the Centre of the TARDIS (TV story)}}) she later began to [[history-proofing|recall certain moments]] of the timeline, ([[TV]]: {{cs|The Name of the Doctor (TV story)}}) and claimed to know the Doctor's name when bluffing to the [[Cybermen]] about being the Doctor. ([[TV]]: {{cs|Death in Heaven (TV story)}}) Additionally, she was able to hear and see River when she said the Doctor's name to open his tomb, but the circumstances of River's saying of the Doctor's name were unknown. ([[TV]]: {{cs|The Name of the Doctor (TV story)}})

====The Supremo====
[[Missy]] claimed to know the Doctor's real name from their time together on Gallifrey. She said it was "Doctor Who", and the Doctor had chosen it to be mysterious, but dropped the "Who" when he realised it was "too on-the-nose". The [[Twelfth Doctor]] said she was just teasing [[Bill Potts]], but he refused to answer if it was truly his name. ([[TV]]: {{cs|World Enough and Time (TV story)}})


For a year, [[Fifth Doctor|the Doctor]] used this alias as leader of [[the Alliance]] against the army of the evil [[renegade Time Lord]] [[Morbius]]. ([[PDA]]: ''[[Warmonger]]'')
== "Doctor Who" ==
[[File:I Am Who.jpg|thumb|The [[First Doctor]], when asked who he is, responds that he is Who. ([[COMIC]]: {{cs|Challenge of the Piper (comic story)}})]]
The name "Doctor Who" was used by or applied to the Doctor on a large number of occasions, with accounts varying on whether this seemed to be the time-traveller's actual name — or at any rate a name they accepted and used for themselves — or simply a placeholder applied to them by others for lack of knowledge of his real names.


:''For an unrelated use of the term, see [[the Supremo]].''
In a [[Dr. Who's reality|version of history "B"]] relative to the [[First Doctor]]'s [[The Doctor's reality (An Unearthly Child)|version of history "A"]], ([[PROSE]]: {{cs|Dalek Survival Guide (novel)}}) an [[Earthling]] [[scientist]] who invented ''[[TARDIS (Dr. Who and the Daleks)|TARDIS]]'' and fought the [[Dalek]]s identified himself as [[Dr. Who (Dr. Who and the Daleks)|Dr. Who]]. ([[TV]]: {{cs|Dr. Who and the Daleks (theatrical film)}}, {{cs|Daleks' Invasion Earth 2150 A.D. (theatrical film)}})


====[[Merlin]] and [[Muldwych]]====
"Dr. Who" was the name by which the First and [[Second Doctor]]s were known during their [[John and Gillian's world|travels]] with their [[grandchildren]], ([[COMIC]]: {{cs|The Klepton Parasites (comic story)}}, {{cs|The Extortioner (comic story)}}) [[John Who|John]] and [[Gillian Who]]. ([[COMIC]]: {{cs|The Incomplete Death's Head (comic story)}}) Accounts differed as to whether these adventures took place in [[the Doctor's universe|reality]] ([[PROSE]]: {{cs|Beware the Trods! (short story)}}, {{cs|The Man Who (Nearly) Killed Christmas (short story)}}) and John and Gillian were truly the Doctor's grandchildren ([[COMIC]]: {{cs|The Klepton Parasites (comic story)}}, et al.) or simulacra, ([[POEM]]: {{cs|The Five O'Clock Shadow (poem)}}) or if they took place in the [[Land of Fiction]] ([[PROSE]]: {{cs|Conundrum (novel)}}) or the Doctor's dreams. ([[COMIC]]: {{cs|The Land of Happy Endings (comic story)}})


This was, [[Seventh Doctor|the Doctor]] believed, an alias used by a future and/or alternative Doctor residing in a [[magic]]-using [[Arthur's World|parallel Earth]]. ([[DW]]: ''[[Battlefield]]'') This was, apparently, a future incarnation of the Doctor who, at times, also used the name '''[[Muldwych]]'''. ([[NA]]: ''[[Happy Endings]]'') (Another account, however, says that another [[renegade Time Lord]] used the alias of [[Merlin]]. ([[ST]]: ''[[One Fateful Knight]]'') See [[Merlin]] and [[Muldwych]].)
The version of the Doctor in the Land of Fiction was known as [[Dr. Who (Land of Fiction)|Dr. Who]]. ([[PROSE]]: {{cs|Prelude Conundrum (short story)}}, {{cs|Conundrum (novel)}}, {{cs|Head Games (novel)}}) While visiting the Land of Fiction, the [[Seventh Doctor]] encountered a "John" and "Gillian" who claimed he was their grandfather in whose company they had fought the [[Klepton]]s and the [[Trod]]s. They tried to make him remember that his name was Dr. Who, to which he flatly replied with denial. When they pressed further and asked if he remembered them, he said that he didn't. ([[PROSE]]: ''[[Conundrum (novel)|Conundrum]]'')


===Minor aliases===
[[Doctor Who (in-universe)|On television]] in the [[1960s]], fans referred to the Doctor as [[Dr. Who (fictional character)|Dr. Who]]. ([[COMIC]]: {{cs|TV Terrors (TVC 709 comic story)}})


====[[First Doctor|First incarnation]]====
The [[Third Doctor]] once stated that his real name was not "Doctor Who", but that others often called him that for lack of him divulging his actual true name. ([[TV]]: {{cs|The Shrink (TV story)}})


=====Maximus Pettulian=====
[[The Master (Terror of the Autons)|The Master]] addressed a [[postcard]] to the Third Doctor as "Dr Who". ([[COMIC]]: {{cs|Fogbound (comic story)}}) [[Missy]] later made two bold claims to [[Bill Potts]] in quick succession, first that "Doctor Who" was in fact the Doctor's real name, and second that it was, more specifically, an alias he had chosen himself [[the Doctor's early life|early on]], as an attempt to "sound mysterious". In this account, he would later drop the "Who" because it was "a tiny bit on-the-nose". The [[Twelfth Doctor]] told Bill she was just trying to wind her up, but he later identified himself as "Doctor Who" to [[Jorj]], noting that he liked the name. ([[TV]]: {{cs|World Enough and Time (TV story)}}) According to one account, a conversation he had with Missy at an earlier point bore out Missy's claim, seeing him explain to her that the name arose from the question of "who to save", calling it "the Doctor's Who". ([[COMIC]]: {{cs|The Road To... (comic story)}})
While visiting the Roman Empire prior to the burning of [[Rome]], the Doctor briefly impersonated a murdered lyre player named [[Maximus Pettulian]] in the court of [[Nero]] until his true identity was uncovered. ([[DW]]: ''[[The Romans]]'')


=====Zeus=====
On the occasion of the reading of [[Quences]]'s will, when Quences insisted that one of the Cousins was missing, [[Glospin]] rhetorically asked the crowd: "Can't you guess ''who'' he means?", emphasising the word. This served to identify the [[First Doctor]], the utterance of whose real name had recently been banned within the House to go along with him being disinherited. ([[PROSE]]: {{cs|Lungbarrow (novel)|chaptnum=7}})
When the [[Greek]] warrior [[Achilles]] mistook the Doctor for Zeus posing as an old man, he went along with it, until the already unconvinced [[Agamemnon]], spoiled the Doctor's ruse. ([[DW]]: ''[[The Myth Makers]]'')  


=====Doctor Caligari=====
When the First Doctor was using the name "Doctor Caligari" and someone remarked, "Doctor who?" he replied, "Yes, quite right."; ([[TV]]: {{cs|The Gunfighters (TV story)}}) similarly, when [[Jimmy Forbes]] asked "Doctor who?", [[The Doctor (Seven Keys to Doomsday)|another incarnation]] of the Doctor replied "Yes, if you like.", ([[AUDIO]]: {{cs|Seven Keys to Doomsday (audio story)}}) and when [[Bruce (Dr. Who For Keep Australia Beautiful)|Citizen 327KL]] asked "Doctor who?", the [[Fourth Doctor]] simply said "yes". ([[TV]]: {{cs|Dr. Who For Keep Australia Beautiful (TV story)}}) When a time-shifted [[Susan Foreman]] was confronted with the [[Sixth Doctor]] without recognising him, and asked "Who are you?", he replied "Precisely! I am the Doctor". ([[TV]]: {{cs|Dimensions in Time (TV story)}}) The [[Fourth Doctor]] outright stated that his name was "Dr Who" when [[Richard I of England|Richard the Lionheart]] asked for his name; King Richard later referred to him as simply "Who".

=====Doctor von Wer=====
The computer [[WOTAN]] repeatedly referred to the First Doctor as "Doctor Who". ([[TV]]: {{cs|The War Machines (TV story)}}) Both [[Ian Chesterton]] and [[Vicki Pallister|Vicki]] occasionally called the Doctor "Doctor Who", ([[PROSE]]: {{cs|Doctor Who and the Zarbi (novelisation)}}) as did [[Argon (Terror on Tiro)|Argon]], ([[PROSE]]: {{cs|Terror on Tiro (short story)}}) [[Mitzog]], ([[PROSE]]: {{cs|The Cloud Exiles (short story)}}) and [[Phlege]]. ([[COMIC]]: {{cs|Mission for Duh (comic story)}}) The Doctor's grandson [[John Who|John]] ([[COMIC]]: {{cs|The Klepton Parasites (comic story)}}) used the last name "Who". ([[PROSE]]: {{cs|Beware the Trods! (short story)}})
'''Doctor von Wer''' was an alias briefly adopted by [[Second Doctor|the Doctor]] during his visit to [[Scotland]] in [[1745]]. It is German for ''Doctor [of] Who'' translated into [[German]]. He also signed a note ''Doctor W'' around this time. ([[DW]]: ''[[The Highlanders]]'')


====[[Third Doctor|Third incarnation]]====
The First Doctor used the username "[[Dr who]]" when bidding on the TARDIS, which he lost to [[Buchanan (The Mother Road)|Buchanan]] in a bet, on [[RetroAuction.com]] in [[2006]]. ([[PROSE]]: {{cs|The Mother Road (short story)}})

<p id="Von Wer">The [[Second Doctor]] briefly used the name "Doktor von Wer" (literally, "Doctor [of] Who") during his visit to Scotland on [[16 April]] [[1746]], ([[TV]]: {{cs|The Highlanders (TV story)}}) and he once signed a message as "Dr W." ([[TV]]: {{cs|The Underwater Menace (TV story)}}) The [[Zaon]]s called him "Doctor Who". ([[PROSE]]: {{cs|Daleks Invade Zaos (short story)}})

[[Bessie]]'s license plate during the [[Third Doctor]]'s time at [[UNIT]] read ''[[WHO 1]]''; ([[TV]]: {{cs|Doctor Who and the Silurians (TV story)}}) in the Doctor's [[seventh incarnation]] it read ''[[WHO 7]]'', ([[TV]]: {{cs|Battlefield (TV story)}}) and ''[[WHO 8]]'' in his [[eighth incarnation]]. ([[PROSE]]: {{cs|The Dying Days (novel)}}) [[Olive Hawthorne|Miss Hawthorne]] referred to the Third Doctor as "the great wizard Qui Quae Quod"; those three words all mean "who" in [[Latin]]. ([[TV]]: {{cs|The Dæmons (TV story)}}) The aged [[Keeper of the Files]] referred to the Doctor with the name "Who". ([[PROSE]]: {{cs|Doctor Who and the Doomsday Weapon (novelisation)}}) [[The Curator]] referred to his [[nose]] as a "Who nose", ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) and after discovering his formative role in [[Davros]]'s early life, the [[Twelfth Doctor]] remarked that "Who made Davros." ([[TV]]: {{cs|The Magician's Apprentice (TV story)}})


=====?=====
The [[Fourth Doctor]] wrote a series of [[Doctor Who Discovers|children's books]] during his time with [[UNIT]] which were mistakenly published under the name "Doctor Who": they were intended to be "The Doctor, Who Discovers Historical Mysteries", but [[Target Books (in-universe)|the publishers]], due to a miscommunication, presented it as "Doctor Who Discovers Historical Mysteries". ([[AUDIO]]: {{cs|The Kingmaker (audio story)}}) [[The Doctor (fictional character)|A version of the Doctor]] in [[David Karpagnon|a young boy]]'s [[imagination]], based off [[The Doctor (fictional character)#Thirteenth Doctor|a fictional depiction of the Doctor]] off [[Doctor Who (in-universe)|television]], claimed that she was "not allowed" to refer to herself as "Doctor Who", despite personally finding it "brilliant". ([[PROSE]]: {{cs|The Terror of the Umpty Ums (short story)}})
The Doctor signed a document with a question mark prior to the the [[Sontaran]] invasion of [[Gallifrey]]. ([[DW]]: ''[[The Invasion of Time]]''). Later, the Doctor's [[Seventh Doctor|seventh incarnation]] signed a document the same way during a visit to [[London]] in [[1963]]. ([[DW]]: ''[[Remembrance of the Daleks]]'')  


====[[Sixth Doctor|Sixth incarnation]]====
[[K9]] occasionally made playful remarks related to the "Who" name. ([[TV]]: {{cs|A Girl's Best Friend (TV story)}}, {{cs|Invasion of the Bane (TV story)}}) [[Clive Finch]]'s [[www.whoisdoctorwho.co.uk|website]] called him "Doctor Who". ([[TV]]: {{cs|Rose (TV story)}}) Upon reading the [[Tenth Doctor]]'s mind, [[Jeanne-Antoinette Poisson|Reinette]] remarked that "Doctor Who" was "more than just a secret". ([[TV]]: {{cs|The Girl in the Fireplace (TV story)}}) [[The Question|The oldest question in the universe]] was "Doctor Who?" ([[TV]]: {{cs|The Wedding of River Song (TV story)}})


=====Doktor of Tardis=====
== Theta Sigma ==
Pseudonym used by [[Sixth Doctor|the Doctor]] to move discreetly around an alternate version of the city of Rome. ([[MA]]: ''[[State of Change]]'')
{{main|Theta Sigma}}
The Doctor's old [[Time Lord Academy|Academy]] schoolmate [[Drax]] knew the Doctor as "Theta Sigma", which he informally shortened to "Thete". The [[Fourth Doctor]] repeatedly corrected him when they met again centuries later, wanting to be called Doctor instead. ([[TV]]: {{cs|The Armageddon Factor (TV story)}})


====[[Tenth Doctor|Tenth incarnation]]====
Some accounts treated "Theta Sigma" as the Doctor's actual, proper name as far as [[Gallifrey]] was concerned; for example, a communication from [[Gallifrey Databank]] to [[Gallifrey High Command]] noted that [[K9 Mark I]] had been modified by "Time Lord Theta Sigma (also known as 'the Doctor')". ([[PROSE]]: {{cs|K9 and the Time Trap (novel)|page=1}}, {{cs|K9 and the Beasts of Vega (novel)|page=1}}, {{cs|K9 and the Zeta Rescue (novel)|page=1}}, {{cs|K9 and the Missing Planet (novel)|page=1}}) In an [[alternate timeline]] in which [[Rassilon]] failed to finish the [[Eye of Harmony]] before his death, the Doctor never left [[Gallifrey]] and became a commentator rather than a [[renegade Time Lord]]. He was known as [[Theta Sigma (Forever)|Commentator Theta Sigma]]. ([[AUDIO]]: {{cs|Forever (audio story)}})


=====Doctor James McCrimmon=====
"ΘΣ" was part of [[River Song]]'s message to the [[Eleventh Doctor]] on the universe's oldest cliff-face. ([[TV]]: {{cs|The Pandorica Opens (TV story)}}) River Song claimed and demonstrated on numerous occasions that she knew the Doctor's secret real name. ([[TV]]: {{cs|Forest of the Dead (TV story)}}, {{cs|The Name of the Doctor (TV story)}}, etc.)
[[Tenth Doctor|The Doctor]] briefly took the name '''Dr. James McCrimmon''' while visiting [[Scotland]] in [[1879]]; this was the name of [[Jamie McCrimmon|one of his old companions]]. Later, however, he dropped the alias and was knighted by [[Queen Victoria]] as "Sir Doctor of TARDIS". ([[DW]]: ''[[Tooth and Claw]]'')


=====Sir Doctor of TARDIS=====
However, the [[Seventh Doctor]] would later claim that "Theta Sigma" was his "nickname at college" to the coincidentally-named [[Trevor Sigma]]. ([[TV]]: {{cs|The Happiness Patrol (TV story)}}) The [[Ninth Doctor]] would later reiterate this in a duel with [[the Grimminy-Grew]] to guess the other's true name, saying that "old school nicknames don't count". ([[AUDIO]]: {{cs|Station to Station (audio story)}})


Aside from being knighted under this name, the Doctor also attempted to use the title when he encountered [[William Shakespeare]], via the psychic paper, but Shakespeare's mind could not be swayed by the paper.([[DW]]:[[The Shakespeare Code]])
In one account, the Doctor considered it a "Time Lord coding", which he couldn't "bear [to be] addressed as". ([[PROSE]]: {{cs|Doctor Who and the Armageddon Factor (novelisation)}}) It identified him uniquely amongst the Time Lords and was not to be spoken outside of the Academy. ([[PROSE]]: {{cs|Falls the Shadow (novel)}}) According to the author of ''[[The Time Lord Letters]]'', a historical document compiling writings by and concerning the Doctor, "Theta Sigma" was also their Academy Student Identification Code. ([[PROSE]] {{cs|The Time Lord Letters (novel)}})


=====Doctor Vile=====
When [[the Doctor (Alien Bodies)|the Doctor's final incarnation]] permanently died during the [[the Cataclysm|first battle]] of the [[War in Heaven]], [[the Relic (Alien Bodies)|his coffin]] had two [[Greek language|Greek]] letters on it; one of these was "Sigma". ([[PROSE]]: {{cs|Alien Bodies (novel)}})
The Doctor briefly masqueraded as the [[space pirate]] '''Doctor Vile''' in order to stop a war. ([[DW]]: ''[[The Infinite Quest]]'')


=====Doctor McCoy=====
== Commonly used aliases ==
After a discussion with [[Donna Noble]], in which she compared the [[sonic screwdriver]] with ''[[Star Trek]]'''s [[Wikipedia:tricorder|tricorder]], the Doctor adopted the alias '''Dr. McCoy''' (after Dr. [[wikipedia:Leonard McCoy|Leonard "Bones" McCoy]], a ''Star Trek'' character) when dealing with a group of soldiers. (Donna called herself [[Captain Kirk]], after [[wikipedia:James T. Kirk|James T. Kirk]], the lead character of the ''Star Trek'' series.) The ruse fell apart when Donna was unable to maintain the pretense of being a captain. ([[NSA]]: ''[[Pest Control]]'')
=== John Smith ===
John Smith was an alias the Doctor frequently used on [[Earth]] and around [[human]]s when a "standard" name was needed, with the [[Eighth Doctor]] noting it was "the ''nom de guerre'' [he] seem[ed] to keep ending up with". ([[PROSE]]: {{cs|Alien Bodies (novel)}}) It was often preceded by the title "Doctor", though not always — for example, when he was undercover as a teacher at a school or a patient in a hospital. ([[TV]]: {{cs|School Reunion (TV story)}}, {{cs|Smith and Jones (TV story)}}) As "John Smith" was considered a generic name in some [[Earth]] cultures, the Doctor's use of the alias was occasionally treated with scepticism. ([[TV]]: {{cs|Midnight (TV story)}})


====='''Spartacus'''=====
The [[First Doctor]] used a library card with the name Dr J. Smith while living at [[76 Totter's Lane]], ([[TV]]: {{cs|The Vampires of Venice (TV story)}}) as well as for identification when renting the junkyard. ([[PROSE]]: {{cs|The Rag & Bone Man's Story (short story)}}) The inspiration for the alias was [[Aubrey Waites|John Smith]] of [[John Smith and the Common Men]], with which he was familiar through Susan. ([[PROSE]]: {{cs|The Witch Hunters (novel)}})
When visiting Pompeii in 79 A.D, The Doctor and Donna both used the Alias 'Spartacus'. Caecilius at first thought they were a married couple, then later thought they were Brother and sister, with The Doctor and Donna simultaneously replying "really?" ([[DW]]:[[The Fires of Pompeii]])


=====Doctor Noble=====
In their [[Second Doctor|second incarnation]], the name was independently used by his [[companion]] [[Jamie McCrimmon]] while the Doctor was being treated for a concussion, as he saw it being used as a brand name on a metal container. ([[TV]]: {{cs|The Wheel in Space (TV story)}}) The Doctor himself used the alias when being interrogated by a German soldier. ([[TV]]: {{cs|The War Games (TV story)}}) Likewise, [[Chang Lee]] chose to register the name for the [[Seventh Doctor]] while he was en route to get his bullet wounds healed. ([[TV]]: {{cs|Doctor Who (TV story)}})
When the Doctor and [[Donna Noble]] travelled to the Ood Sphere, he used the Alias '''Dr. Noble''' this led to people confusing the Doctor and Donna for a married couple. ([[DW]]: ''[[Planet of the Ood]]'')


=====The Time Lord Victorious=====
The Doctor adopted the name on a semi-regular basis during their [[Third Doctor|third incarnation]] while [[Exile on Earth|exiled on Earth]], when he served as unpaid [[scientific advisor]] to [[UNIT]]. ([[TV]]: {{cs|Spearhead from Space (TV story)}}, {{cs|Inferno (TV story)}}, {{cs|The Time Warrior (TV story)}}) The UNIT files referred to him as "Dr. J.S.". ([[AUDIO]]: {{cs|Tales from the Vault (audio story)}})
Deciding to alter history by rescuing [[Adelaide Brooke]] and two of her comrades from [[Bowie Base One]] on Mars in 2059, the Doctor became arrogant and egotistical, declaring that the laws of the Time Lords to prevent altering history no longer applied because he was the last, so he had total authority over time itself. He called himself "the Time Lord Victorious" and dismissively referred to the other survivors, [[Mia Bennett]] and [[Yuri Kerenski]], as "little people". An indignant Adelaide shot back that "the Time Lord Victorious is wrong" and subsequently committed suicide, which largely preserved the timeline the Doctor had altered. ([[DW]]: ''[[The Waters of Mars]]'')


==Names given to the Doctor by others==
The Doctor twice changed himself into a human who used the name John Smith. This occurred [[John Smith (Seventh Doctor)|in their seventh incarnation]], ([[PROSE]]: {{cs|Human Nature (novel)}}) and [[John Smith (Tenth Doctor)|in their tenth incarnation]]. ([[TV]]: {{cs|Human Nature (TV story)}})


===Major===
Often, the Doctor would use variations of the name, like the online handle "[[jsmith]]", [[jsmith8]]", ([[PROSE]]: {{cs|Blue Box (novel)}}, {{cs|Lonely (short story)}}) the French variation "Jean Forgeron", ([[COMIC]]: {{cs|The Forgotten (comic story)}}) or the [[German language|German]] translation "Johann Schmidt". ([[PROSE]]: {{cs|The Shadow in the Glass (novel)}}; [[AUDIO]]: {{cs|Storm Warning (audio story)}})


====The Evil One====
The [[Thirteenth Doctor]] once made use of a variant, "Jane Smith", while hiding her true identity from [[Martha Jones]]. ([[COMIC]]: {{cs|A Little Help from My Friends (comic story)}})
The [[Sevateem]] tribe referred to the Doctor as '''The Evil One''', due to the fact that [[Xoanon|the supercomputer they worshipped]] had a split personality, one of which was based on that of [[Fourth Doctor|the Doctor]]. ([[DW]]: ''[[The Face of Evil]]'')


====Ka Faraq Gatri and other Dalek names====
By one account, "John Smith" was the name by which the [[Tenth Doctor (Journey's End)|Meta-Crisis Tenth Doctor]] chose to go upon settling down with [[Rose Tyler]]. ([[COMIC]]: {{cs|Empire of the Wolf (comic story)}})
The [[Dalek]]s referred to the Doctor as the '''Ka Faraq Gatri''', which may mean '''Bringer of Darkness''' and/or '''Destroyer of Worlds'''. By implication, the name Destroyer of Worlds referred to the Doctor's destruction of the Dalek home [[planet]] [[Skaro]] in his [[Seventh Doctor|seventh incarnation]], an act for which he would consequently feel some remorse. ([[DW]]:''[[Remembrance of the Daleks]]'', [[NA]]: ''[[Timewyrm: Revelation]])'' However, as early as his [[Second Doctor|second incarnation]], the Doctor knew that the Daleks had given him this name, and the Daleks used it prior to the destruction of Skaro. ([[DWM]]: ''[[Bringer of Darkness]]'', [[DWN]]: ''[[Remembrance of the Daleks (novelisation)|Remembrance of the Daleks]]''). The name was again used by [[Davros]] following his defeat during the [[Dalek Invasion of Earth (2009)|Medusa Cascade incident]]. ([[DW]]: ''[[Journey's End]]'')


: ''It is possible that the latter name was what Evelina referred to when she said the Doctor's "true name...burns in the stars, in the [[Medusa_Cascade|cascade of Medusa herself]]". [[The_Fires_of_Pompeii|(DW: The Fires of Pompeii)]]''
The Tenth Doctor attempted to use this alias when he met the Fourth Doctor. However, he opted out of the second half and instead used [[Rose Tyler|Rose]]'s last name, ending up with "[[John Tyler]]" instead. ([[AUDIO]]: {{cs|Out of Time (audio story)}})


====The Dark Lord/The Threefold Man====
=== The Oncoming Storm ===
[[Dalek Caan]] referred to [[Tenth Doctor|the Doctor]] as "'''the Dark Lord'''" or "'''the Threefold Man'''" during the [[Dalek Invasion of Earth (2009)|Medusa Cascade incident]] ([[DW]]: ''[[The Stolen Earth]]''/''[[Journey's End]]'').
{{main|The Oncoming Storm}}
The Doctor was referred to as "the Oncoming Storm" by the [[Draconian]]s, ([[PROSE]]: {{cs|Love and War (novel)}}) himself ([[PROSE]]: {{cs|Vampire Science (novel)}}) and in "the ancient legends of the [[Dalek]] [[Skaro|homeworld]]". ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) In [[Draconian (language)|Draconian]], the title was pronounced "Karshtakavaar". ([[PROSE]]: {{cs|Love and War (novel)}}) After being told of the title by the [[Ninth Doctor]], ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) [[Rose Tyler]] called the [[Tenth Doctor]] by the "Oncoming Storm" when she and [[Mickey Smith]] were being prepared for dissection by the [[Clockwork Droid]]s. ([[TV]]: {{cs|The Girl in the Fireplace (TV story)}})


====The Oncoming Storm====
The Tenth Doctor later introduced himself as the "Oncoming Storm" to a [[Dalek (Prisoner of the Daleks)|Dalek]] aboard of the ''[[Wayfarer]]'', ([[PROSE]]: {{cs|Prisoner of the Daleks (novel)}}) and referred to the title when confronting a [[rabbit]] he thought was a [[Zygon]]. ([[TV]]: {{cs|The Day of the Doctor (TV story)}})
The [[Dalek]]s also referred to the Doctor as the '''Oncoming Storm''' in the myths of [[Skaro|their homeworld]], as noted by his [[Ninth Doctor|ninth incarnation]], indicating that the Daleks feared him. ([[DW]]: ''[[The Parting of the Ways]]'') This was also the name given to him by the [[Draconian]]s, ("Karshtakavaar" in Draconian) who were generally the Doctor's allies, to indicate the traumatic events which so often accompanied his arrival. ([[NA]]: ''[[Love and War]]'') However the Doctor was also reffered to by this name by the seers in Pompei. ([[DW|DW:]] [[The Fires of Pompeii]])


====Time's Champion====
The [[Eleventh Doctor]] began calling himself the "Oncoming Storm" when he misinterpreted [[Sean (The Lodger)|Sean]]'s request to help the [[King's Arms, Colchester|King's Arms]] football team "annihilate" another team at a match. ([[TV]]: {{cs|The Lodger (TV story)}}) He later referred to the title when the Daleks forgot him. ([[TV]]: {{cs|Asylum of the Daleks (TV story)}})
'''Time's Champion''' was a title given to the Doctor to symbolise his service to [[Time (Eternal)|Time]] during his [[Seventh Doctor|seventh incarnation]]. ([[NA]]: ''[[Love and War]]'')


====The Sandman====
=== Destroyer of Worlds ===
The [[Sixth Doctor|Doctor]]'s actions in the past of the [[Galyari]] led to his entering their race memory as a legendary monster called the '''Sandman'''. ([[BFA]]: ''[[The Sandman]]'')
As early as their [[Second Doctor|second incarnation]], the Doctor knew that the Daleks had also given them the epithet "[[Ka Faraq Gatri]]", ([[COMIC]]: {{cs|Bringer of Darkness (comic story)}}) which translated as "[[Destroyer of Worlds]]". ([[PROSE]]: {{cs|Timewyrm: Revelation (novel)}}) or possibly, "Nice guy, if you're a [[biped]]". ([[PROSE]]: {{cs|Continuity Errors (short story)}}) He had been awarded the name upon orchestrating the destruction of the Dalek home [[planet]] [[Skaro]] in his [[Seventh Doctor|seventh incarnation]], ([[TV]]: {{cs|Remembrance of the Daleks (TV story)}}) though the Daleks also used it prior to Skaro's destruction. ([[COMIC]]: {{cs|Bringer of Darkness (comic story)}}) [[Davros]] also referred to the Doctor as "the Destroyer of Worlds" after the [[Meta-Crisis Tenth Doctor]] destroyed the [[New Dalek Empire]] on the [[Crucible]]. ([[TV]]: {{cs|Journey's End (TV story)}})


====Rides In Night====

([[PROSE]]: {{cs|The Juror's Story (short story)}})
** Doctor I. M. Foreman: The Doctor's application for [[Susan Foreman]]'s admittance into [[Coal Hill School]] used this alias. ([[PROSE]]: {{cs|The Time Lord Letters (novel)}})

After seeing his arrival in the TARDIS, she mistook him for the island's protector from [[Norse mythology]]. He believed that it was simplest to accept the name. The name meant "Wise Old Chieftain," which Ian thought was appropriate. ([[AUDIO]]: {{cs|The Revenants (audio story)}})

====Doctor Who====
=== Nicknames ===

== Behind the scenes ==
=== The Doctor's name ===
{{section cleanup|Outdated, the name is used in [[The Trial of Doctor Who (short story)]] which clarifies its usage.}}
* The first edition of the behind-the-scenes book ''[[The Making of Doctor Who]]'', published in 1972, stated that the Doctor's name was "∂³∑x²". It was later spelt as "d³ᓬx²" in the "Who is the Doctor" prologue of [[Marvel Premiere]] #57 in 1980. This has never been confirmed in any ''Doctor Who'' narrative, but these letters do appear on the plinth in the [[Tomb of Rassilon]] in ''[[The Five Doctors (TV story)|The Five Doctors]]''.

Ian Chesterton and Barbara Wright meet "Dr Foreman". (TV: "An Unearthly Child" [+]Part of An Unearthly Child, Loading...{"namedep":"An Unearthly Child (1)","1":"An Unearthly Child (TV story)"})

Throughout their travels in time and space, the Doctor took on and was called by a number of different aliases, titles and names. Some were fleeting, while others, like John Smith, were used by almost all of their incarnations, with some variations. The Doctor told very few people their original name, instead asking others to simply call them the Doctor. By many accounts, the Doctor considered this title to be their real name. (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"] et al.) It was their chosen identity, and a promise to the universe. (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"], The Beast Below [+]Loading...["The Beast Below (TV story)"], The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"])

In other accounts, however, the Doctor's "true name" was the one which was hidden, a guarded secret the Doctor kept from almost everyone. (TV: The Girl in the Fireplace [+]Loading...["The Girl in the Fireplace (TV story)"], The Shakespeare Code [+]Loading...["The Shakespeare Code (TV story)"], The Fires of Pompeii [+]Loading...["The Fires of Pompeii (TV story)"], The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"]) Most names the Doctor kept were a matter of convenience, and they were prone to take on whichever name would help them blend in best, or stand out more, depending on the situation. Some companions felt this was not the Doctor's strongest suit, however. (AUDIO: What Just Happened? [+]Loading...["What Just Happened? (audio story)"] et al.)

The Doctor's real name[[edit] | [edit source]]

Most accounts treated the Doctor's true name as a complete mystery. Bill Potts, his student, asserted that "nobody [knew] the Doctor's real name", although Missy claimed that she was an exception to this given that she "grew up with him". (TV: World Enough and Time [+]Loading...["World Enough and Time (TV story)"]) One account even implied that their given name was ceremoniously withdrawn and stricken by their Cousins as punishment for a disgrace the Doctor had brought upon their House. (PROSE: Lungbarrow [+]Loading...["Lungbarrow (novel)"]) By another account, it had "broke" into as many pieces as there were syllables it took to say, and he gifted a piece to some of those he met on his travels. (PROSE: Return of the Living Dad [+]Loading...["Return of the Living Dad (novel)"]) However, the Doctor's true name did appear in secret files created by the High Court of the Time Lords, containing a transcript of the Doctor's trial, where it was spelled as "∂³Σx²". (PROSE: The Trial of Doctor Who [+]Loading...["The Trial of Doctor Who (short story)"]) While wandering in the Doctor's TARDIS, Clara Oswald read a history of the Time War which apparently told her the Doctor's name, causing her to remark "So that's who." (TV: Journey to the Centre of the TARDIS [+]Loading...["Journey to the Centre of the TARDIS (TV story)"])

Even when put on trial by the Time Lords, they were only referred to as "the Doctor", (TV: The War Games [+]Loading...["The War Games (TV story)"]) although the Valeyard, a culmination of the Doctor's darker side who prosecuted the second trial, acknowledged that this was an alias. (TV: The Mysterious Planet [+]Loading...["The Mysterious Planet (TV story)"]) When the Fifth Doctor was officially inducted as Lord President, he declared that it was "out of the question" for him to be introduced by his true name, stating that he would accept being introduced as "Lord President Doctor". (AUDIO: Time in Office [+]Loading...["Time in Office (audio story)"]) Even those who had known them in childhood addressed them only as "the Doctor", such as the Master, (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"]) and the Rani. (COMIC: Weapons of Past Destruction [+]Loading...["Weapons of Past Destruction (comic story)"])

According to one account, during their first incarnation, the Doctor adopted this name in dealing with human colonists on the planet Iwa at the same time that his granddaughter adopted the name "Susan". (PROSE: Frayed [+]Loading...["Frayed (novel)"]) Other accounts implied that the Doctor's title had been chosen as a Gallifreyan custom, (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"]) and that he had been using it before he left Gallifrey. (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"], World Enough and Time [+]Loading...["World Enough and Time (TV story)"])

The Doctor's real name has been said to be difficult to pronounce, for humans at least, (PROSE: Doctor Who and the Auton Invasion [+]Loading...["Doctor Who and the Auton Invasion (novelisation)"], AUDIO: Slipback [+]Loading...["Slipback (audio story)"]) and certainly for adults, (TV: Twice Upon a Time [+]Loading...["Twice Upon a Time (TV story)"]) possessing thirty eight syllables. (PROSE: SLEEPY [+]Loading...["SLEEPY (novel)"], Return of the Living Dad [+]Loading...["Return of the Living Dad (novel)"]) The First Doctor once told an interrogator he "wouldn't be able to pronounce the first syllable of [his name]." (PROSE: Salvation [+]Loading...["Salvation (novel)"]) His seventh incarnation likewise told one of his captors that he "doubt[ed] [they]'d be able to pronounce the name [he] was originally given." (PROSE: Illegal Alien [+]Loading...["Illegal Alien (novel)"]) When asked about the Doctor's name, Peri Brown once said that the Doctor had told her she would find it unpronounceable. (AUDIO: Slipback [+]Loading...["Slipback (audio story)"])

However, the First Minister of Chance once answered similarly when asked what his real name was, only to play it off as a joke and explain that "the Minister" was his real name, with this simply being how Time Lord names worked. (WC: Death Comes to Time [+]Loading...["Death Comes to Time (webcast)"]) The Fifteenth Doctor similarly suggested that all Time Lord names were titles, and that the original name he had discarded for "the Doctor" was already a "the" title; he prepared to tell it to Ruby Sunday as they stepped out of the TARDIS control room, getting at least as far as "the". (TV: Space Babies [+]Loading...["Space Babies (TV story)"])

Moments before his regeneration, the Twelfth Doctor stated his belief that "children [could] hear [his name]", but only when "their hearts [were] in the right place, and the stars [were] too", adding: "but nobody else… nobody else… ever", emphasising to his uncreated next self that she "mustn't ever tell anyone [her] name". (TV: Twice Upon a Time [+]Loading...["Twice Upon a Time (TV story)"])

The Doctor kept their true name hidden despite numerous "mind-probe" attempts and the effect of a truth field. (TV: The Girl in the Fireplace [+]Loading...["The Girl in the Fireplace (TV story)"], The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"]) The Carrionite Lilith, unable to discover the Tenth Doctor's true name even with the "witchcraft" used by her kind, remarked that "there [was] no name," and that the Doctor was hiding it in despair. (TV: The Shakespeare Code [+]Loading...["The Shakespeare Code (TV story)"]) The psychically-gifted Evelina, who attempted to foretell the Doctor's future, remarked that his "true name" was "hidden" from her. (TV: The Fires of Pompeii [+]Loading...["The Fires of Pompeii (TV story)"])

By one account, in his youth, the Doctor had outright removed his name from time, all but he and the Master forgetting his birth name. (AUDIO: Blood of the Time Lords [+]Loading...["Blood of the Time Lords (audio story)"])

Significance[[edit] | [edit source]]

By one account, names held mystic importance in Time Lord society, meaning that all Time Lords kept their true names as closely-guarded secrets. In this sense, the Doctor's name was not any more or less significant than any other Time Lord's. (PROSE: Doctor Who and the Auton Invasion [+]Loading...["Doctor Who and the Auton Invasion (novelisation)"])

The Eleventh Doctor told Clara Oswald that his original name was not important since he specifically chose the title of "Doctor" to take its place, saying it was "like a promise [one made]." (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"]) This promise was; "Never cruel or cowardly. Never give up, never give in." (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"]) Even Clara considered "the Doctor" to be his true name and the only one that mattered. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"]) Despite their hatred of the War Doctor's actions, (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"]) both the tenth and eleventh incarnations admitted "[he] was the Doctor more than [any of them]." (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"]) When Clara was forced to take on his role for him, the Twelfth Doctor told her that "goodness has nothing to do with [being a Doctor]". (TV: Flatline [+]Loading...["Flatline (TV story)"])

The Doctor considered abandoning his name if he felt he had to do something highly immoral. (TV: The Beast Below [+]Loading...["The Beast Below (TV story)"], Face the Raven [+]Loading...["Face the Raven (TV story)"]) The War Doctor rejected the name to fight in the Time War, (TV: The Night of the Doctor [+]Loading...["The Night of the Doctor (TV story)"]) but proudly called himself the Doctor once he was given the chance to end the conflict without killing the Time Lords. (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"]) During his final day, the Twelfth Doctor stated being "the Doctor" was being kind, even if it meant pulling a self-sacrifice to bring others a small amount of extra time to live. (TV: The Doctor Falls [+]Loading...["The Doctor Falls (TV story)"]) The Thirteenth Doctor said that a "bit of adrenaline, dash of outrage and a hint of panic" helped her to remember she was the Doctor. (TV: The Woman Who Fell to Earth [+]Loading...["The Woman Who Fell to Earth (TV story)"])

The Saxon Master knew of this and implied that the Doctor's title had been chosen because it meant "the man who makes people better", although he found the choice "sanctimonious" for someone who ended millions of lives and ruined many others. (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"]) River Song was aware of this contradiction in the Doctor's behaviour: she said that the Doctor was the first to have this title and that the rest of the universe later adopted it, usually to mean "healer" or "wise man". However, she added that, in some parts of the universe, such as in the Gamma Forests, it eventually came to mean "mighty warrior". (TV: A Good Man Goes to War [+]Loading...["A Good Man Goes to War (TV story)"])

According to Dorium Maldovar, the Silence had a particular interest in the Doctor's name. He explained that if the Doctor lived long enough, "on the fields of Trenzalore, at the fall of the Eleventh, [when] no creature could speak falsely or fail to answer", a question that must never be answered would be asked: "Doctor Who?". The Silence wanted to stop the Doctor from revealing his true name. (TV: The Wedding of River Song [+]Loading...["The Wedding of River Song (TV story)"])

The Doctor was at a later time forced to go to Trenzalore to rescue his friends from the Great Intelligence, which sought to gain access to the Doctor's tomb. The tomb, which was a future version of his own dying TARDIS, would open only to the Doctor's real name. The Intelligence threatened to kill Clara Oswald and the Paternoster Gang if he did not speak his name and open the tomb; the situation was resolved when the data ghost of River Song was able to silently transmit his name to the TARDIS, thus opening the door for the Great Intelligence. (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"])

The Doctor's real name became important during the Siege of Trenzalore, as it was the signal chosen by the Time Lords to come back to the universe, broadcasting the question "Doctor Who?" through a crack in reality, simultaneously broadcasting a Truth Field so that they could be sure that it was truly the Doctor responding to them. Despite this, when the Doctor was facing death, Clara told the Time Lords through the Crack that the only name of his that mattered was "the Doctor" and everything he stood for under that name, prompting them to give the Doctor a new regeneration cycle at the cost of closing the crack. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"])

After meeting his twelfth incarnation, the First Doctor was confronted by the mysterious Testimony Foundation, who claimed that the Doctor was the "Doctor of War". Although the First Doctor initially feared this interpretation of his future, after witnessing the Twelfth Doctor's efforts to save Captain Archibald Hamish Lethbridge-Stewart, he came to conclude that the "Doctor of War" was not a man who revelled in war, but a man who sought the moments of peace that existed amid open warfare, and who would always try to find another way to end war, and to find resolution, rather than resorting to bloodshed. (TV: Twice Upon a Time [+]Loading...["Twice Upon a Time (TV story)"])

Ubiquity of the title[[edit] | [edit source]]

The Doctor did possess at least one doctorate. (TV: The Moonbase [+]Loading...["The Moonbase (TV story)"], The Armageddon Factor [+]Loading...["The Armageddon Factor (TV story)"], The Mysterious Planet [+]Loading...["The Mysterious Planet (TV story)"]) They sometimes described themselves as a "doctor of many things" (TV: Four to Doomsday [+]Loading...["Four to Doomsday (TV story)"]) or of "everything", (TV: Spearhead from Space [+]Loading...["Spearhead from Space (TV story)"], Utopia [+]Loading...["Utopia (TV story)"]) as well as "a scientist, an engineer, builder of things". (TV: The Aztecs [+]Loading...["The Aztecs (TV story)"]) However, their knowledge was limited to anything prior to the Rassilon Era. (TV: Utopia [+]Loading...["Utopia (TV story)"]) The Eleventh Doctor claimed that one of his doctorates was in cheesemaking, (TV: The God Complex [+]Loading...["The God Complex (TV story)"]) but only the "stinky, blue kind". (PROSE: Shroud of Sorrow [+]Loading...["Shroud of Sorrow (novel)"])

On several occasions, the Doctor claimed they were not a medical doctor. (TV: "The Forest of Fear" [+]Part of An Unearthly Child, Loading...{"namedep":"The Forest of Fear (3)","1":"An Unearthly Child (TV story)"}, "Mighty Kublai Khan" [+]Part of Marco Polo, Loading...{"namedep":"Mighty Kublai Khan (6)","1":"Marco Polo (TV story)"}) Though by their second incarnation, he had studied medicine in the 19th century, (TV: The Moonbase [+]Loading...["The Moonbase (TV story)"]) although Clara recalled the Doctor telling her that he graduated in the wrong century. (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"]) The Eleventh Doctor described himself as a medical doctor. (TV: The God Complex [+]Loading...["The God Complex (TV story)"]) The seventh, eleventh and twelfth incarnations displayed some medical knowledge, being able to help with minor injuries (TV: Remembrance of the Daleks [+]Loading...["Remembrance of the Daleks (TV story)"], The Vampires of Venice [+]Loading...["The Vampires of Venice (TV story)"]) and tell if a person was vitamin deficient. (TV: Thin Ice [+]Loading...["Thin Ice (TV story)"]) The Ninth Doctor could also diagnose patients in a hospital ward, quickly deducing they all shared the injuries of a scar on the back of their hands, collapsed chest cavities, crushed rib cages and gas masks fused into the flesh on their faces, (TV: The Empty Child [+]Loading...["The Empty Child (TV story)"]) and displayed extensive knowledge on nanogenes, such as their ability to repair organic matter and restore life as a mere "quirk of matter". (TV: The Doctor Dances [+]Loading...["The Doctor Dances (TV story)"]) The Tenth Doctor in particular proved a proficient medic, performing life-saving surgery on Laszlo, sustaining him as a Human-Pig hybrid, able to live as long as a human again. (TV: Evolution of the Daleks [+]Loading...["Evolution of the Daleks (TV story)"])

When asked by Mabli if her doctorate was in medicine, the Thirteenth Doctor described herself as having a doctorate in "medicine, science, engineering, candyfloss, Lego, philosophy, music, problems, people, [and] hope." (TV: The Tsuranga Conundrum [+]Loading...["The Tsuranga Conundrum (TV story)"])

Individuals with knowledge of the Doctor's name[[edit] | [edit source]]

Susan Foreman knew the Doctor's real name, and wrote it on the wrappings of a hypercube she sent to him after she had settled down on Earth. (PROSE: Ghost of Christmas Past [+]Loading...["Ghost of Christmas Past (short story)"])

Ace knew his true name's signature, written using three runes but able to be condensed into one. (PROSE: Timewyrm: Revelation [+]Loading...["Timewyrm: Revelation (novel)"]) The Seventh Doctor, half-unconscious, once told two Caxtarids his name, which they remarked as being "hard getting [...] on the front of an envelope." (PROSE: Return of the Living Dad [+]Loading...["Return of the Living Dad (novel)"])

The Sixth Doctor told his dance instructor, Becky, his name. (PROSE: Teach Yourself Ballroom Dancing [+]Loading...["Teach Yourself Ballroom Dancing (short story)"])

The Eighth Doctor used his real name when he forged passes for himself and his companion, Sam Jones, on board the Cirrandaria in 3123. He used this name when speaking to a guard, Sam finding it quite alien and virtually unpronounceable. (PROSE: Vanderdeken's Children [+]Loading...["Vanderdeken's Children (novel)"])

When the Tenth Doctor first encountered her, River Song claimed to have known him at some point in his future, (TV: Silence in the Library [+]Loading...["Silence in the Library (TV story)"]) and, to prove her "credentials", she whispered his name in his ear, and apologised for having to do so. The Doctor was shocked at this, as "there [was] only one reason [he] would ever tell anyone [his] name, [and] only one time [he] could." (TV: Forest of the Dead [+]Loading...["Forest of the Dead (TV story)"]) River indicated to Clara Oswald that she "made" the Doctor tell her his name and that "it took a lot of effort". (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"])

Near the end of his life, despite believing there was no one left in the universe who knew it, the Tenth Doctor encountered members of an unidentified pan-dimensional race that knew his real name. (AUDIO: The Last Voyage [+]Loading...["The Last Voyage (audio story)"])

While separated from the Eleventh Doctor, Clara Oswald read his name in The History of the Time War. Though that timeline was aborted, leaving her with no memory of it, (TV: Journey to the Centre of the TARDIS [+]Loading...["Journey to the Centre of the TARDIS (TV story)"]) she later began to recall certain moments of the timeline, (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"]) and claimed to know the Doctor's name when bluffing to the Cybermen about being the Doctor. (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"]) Additionally, she was able to hear and see River when she said the Doctor's name to open his tomb, but the circumstances of River's saying of the Doctor's name were unknown. (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"])

Missy claimed to know the Doctor's real name from their time together on Gallifrey. She said it was "Doctor Who", and the Doctor had chosen it to be mysterious, but dropped the "Who" when he realised it was "too on-the-nose". The Twelfth Doctor said she was just teasing Bill Potts, but he refused to answer if it was truly his name. (TV: World Enough and Time [+]Loading...["World Enough and Time (TV story)"])

"Doctor Who"[[edit] | [edit source]]

The First Doctor, when asked who he is, responds that he is Who. (COMIC: Challenge of the Piper [+]Loading...["Challenge of the Piper (comic story)"])

The name "Doctor Who" was used by or applied to the Doctor on a large number of occasions, with accounts varying on whether this seemed to be the time-traveller's actual name — or at any rate a name they accepted and used for themselves — or simply a placeholder applied to them by others for lack of knowledge of his real names.

In a version of history "B" relative to the First Doctor's version of history "A", (PROSE: Dalek Survival Guide [+]Loading...["Dalek Survival Guide (novel)"]) an Earthling scientist who invented TARDIS and fought the Daleks identified himself as Dr. Who. (TV: Dr. Who and the Daleks [+]Loading...["Dr. Who and the Daleks (theatrical film)"], Daleks' Invasion Earth 2150 A.D. [+]Loading...["Daleks' Invasion Earth 2150 A.D. (theatrical film)"])

"Dr. Who" was the name by which the First and Second Doctors were known during their travels with their grandchildren, (COMIC: The Klepton Parasites [+]Loading...["The Klepton Parasites (comic story)"], The Extortioner [+]Loading...["The Extortioner (comic story)"]) John and Gillian Who. (COMIC: The Incomplete Death's Head [+]Loading...["The Incomplete Death's Head (comic story)"]) Accounts differed as to whether these adventures took place in reality (PROSE: Beware the Trods! [+]Loading...["Beware the Trods! (short story)"], The Man Who [+]Loading...["The Man Who (Nearly) Killed Christmas (short story)"]) and John and Gillian were truly the Doctor's grandchildren (COMIC: The Klepton Parasites [+]Loading...["The Klepton Parasites (comic story)"], et al.) or simulacra, (POEM: The Five O'Clock Shadow [+]Loading...["The Five O'Clock Shadow (poem)"]) or if they took place in the Land of Fiction (PROSE: Conundrum [+]Loading...["Conundrum (novel)"]) or the Doctor's dreams. (COMIC: The Land of Happy Endings [+]Loading...["The Land of Happy Endings (comic story)"])

The version of the Doctor in the Land of Fiction was known as Dr. Who. (PROSE: Prelude Conundrum [+]Loading...["Prelude Conundrum (short story)"], Conundrum [+]Loading...["Conundrum (novel)"], Head Games [+]Loading...["Head Games (novel)"]) While visiting the Land of Fiction, the Seventh Doctor encountered a "John" and "Gillian" who claimed he was their grandfather in whose company they had fought the Kleptons and the Trods. They tried to make him remember that his name was Dr. Who, to which he flatly replied with denial. When they pressed further and asked if he remembered them, he said that he didn't. (PROSE: Conundrum)

On television in the 1960s, fans referred to the Doctor as Dr. Who. (COMIC: TV Terrors [+]Loading...["TV Terrors (TVC 709 comic story)"])

The Third Doctor once stated that his real name was not "Doctor Who", but that others often called him that for lack of him divulging his actual true name. (TV: The Shrink [+]Loading...["The Shrink (TV story)"])

The Master addressed a postcard to the Third Doctor as "Dr Who". (COMIC: Fogbound [+]Loading...["Fogbound (comic story)"]) Missy later made two bold claims to Bill Potts in quick succession, first that "Doctor Who" was in fact the Doctor's real name, and second that it was, more specifically, an alias he had chosen himself early on, as an attempt to "sound mysterious". In this account, he would later drop the "Who" because it was "a tiny bit on-the-nose". The Twelfth Doctor told Bill she was just trying to wind her up, but he later identified himself as "Doctor Who" to Jorj, noting that he liked the name. (TV: World Enough and Time [+]Loading...["World Enough and Time (TV story)"]) According to one account, a conversation he had with Missy at an earlier point bore out Missy's claim, seeing him explain to her that the name arose from the question of "who to save", calling it "the Doctor's Who". (COMIC: The Road To... [+]Loading...["The Road To... (comic story)"])

On the occasion of the reading of Quences's will, when Quences insisted that one of the Cousins was missing, Glospin rhetorically asked the crowd: "Can't you guess who he means?", emphasising the word. This served to identify the First Doctor, the utterance of whose real name had recently been banned within the House to go along with him being disinherited. (PROSE: Lungbarrow [+]Loading...{"chaptnum":"7","1":"Lungbarrow (novel)"})

When the First Doctor was using the name "Doctor Caligari" and someone remarked, "Doctor who?" he replied, "Yes, quite right."; (TV: The Gunfighters [+]Loading...["The Gunfighters (TV story)"]) similarly, when Jimmy Forbes asked "Doctor who?", another incarnation of the Doctor replied "Yes, if you like.", (AUDIO: Seven Keys to Doomsday [+]Loading...["Seven Keys to Doomsday (audio story)"]) and when Citizen 327KL asked "Doctor who?", the Fourth Doctor simply said "yes". (TV: Dr. Who For Keep Australia Beautiful [+]Loading...["Dr. Who For Keep Australia Beautiful (TV story)"]) When a time-shifted Susan Foreman was confronted with the Sixth Doctor without recognising him, and asked "Who are you?", he replied "Precisely! I am the Doctor". (TV: Dimensions in Time [+]Loading...["Dimensions in Time (TV story)"]) The Fourth Doctor outright stated that his name was "Dr Who" when Richard the Lionheart asked for his name; King Richard later referred to him as simply "Who". (PROSE: Doctor Who Discovers The Conquerors [+]Loading...["Doctor Who Discovers The Conquerors (novel)"])

The TARDIS-Keeper on Gallifrey also knew the Doctor as "Who". (PROSE: Doctor Who and the Doomsday Weapon [+]Loading...["Doctor Who and the Doomsday Weapon (novelisation)"])

The computer WOTAN repeatedly referred to the First Doctor as "Doctor Who". (TV: The War Machines [+]Loading...["The War Machines (TV story)"]) Both Ian Chesterton and Vicki occasionally called the Doctor "Doctor Who", (PROSE: Doctor Who and the Zarbi [+]Loading...["Doctor Who and the Zarbi (novelisation)"]) as did Argon, (PROSE: Terror on Tiro [+]Loading...["Terror on Tiro (short story)"]) Mitzog, (PROSE: The Cloud Exiles [+]Loading...["The Cloud Exiles (short story)"]) and Phlege. (COMIC: Mission for Duh [+]Loading...["Mission for Duh (comic story)"]) The Doctor's grandson John (COMIC: The Klepton Parasites [+]Loading...["The Klepton Parasites (comic story)"]) used the last name "Who". (PROSE: Beware the Trods! [+]Loading...["Beware the Trods! (short story)"])

The First Doctor used the username "Dr who" when bidding on the TARDIS, which he lost to Buchanan in a bet, on RetroAuction.com in 2006. (PROSE: The Mother Road [+]Loading...["The Mother Road (short story)"])

The Second Doctor briefly used the name "Doktor von Wer" (literally, "Doctor [of] Who") during his visit to Scotland on 16 April 1746, (TV: The Highlanders [+]Loading...["The Highlanders (TV story)"]) and he once signed a message as "Dr W."

(AUDIO: The Kingmaker [+]Loading...["The Kingmaker (audio story)"]) A version of the Doctor in a young boy's imagination, based off a fictional depiction of the Doctor off television, claimed that she was "not allowed" to refer to herself as "Doctor Who", despite personally finding it "brilliant".

Theta Sigma[[edit] | [edit source]]

Main article: Theta Sigma

The Doctor's old Academy schoolmate Drax knew the Doctor as "Theta Sigma", which he informally shortened to "Thete". The Fourth Doctor repeatedly corrected him when they met again centuries later, wanting to be called Doctor instead. (TV: The Armageddon Factor [+]Loading...["The Armageddon Factor (TV story)"])

Some accounts treated "Theta Sigma" as the Doctor's actual, proper name as far as Gallifrey was concerned; for example, a communication from Gallifrey Databank to Gallifrey High Command noted that K9 Mark I had been modified by "Time Lord Theta Sigma (also known as 'the Doctor')". (PROSE: K9 and the Time Trap [+]Loading...{"page":"1","1":"K9 and the Time Trap (novel)"}, K9 and the Beasts of Vega [+]Loading...{"page":"1","1":"K9 and the Beasts of Vega (novel)"}, K9 and the Zeta Rescue [+]Loading...{"page":"1","1":"K9 and the Zeta Rescue (novel)"}, K9 and the Missing Planet [+]Loading...{"page":"1","1":"K9 and the Missing Planet (novel)"}) In an alternate timeline in which Rassilon failed to finish the Eye of Harmony before his death, the Doctor never left Gallifrey and became a commentator rather than a renegade Time Lord. He was known as Commentator Theta Sigma. (AUDIO: Forever [+]Loading...["Forever (audio story)"])

"ΘΣ" was part of River Song's message to the Eleventh Doctor on the universe's oldest cliff-face. (TV: The Pandorica Opens [+]Loading...["The Pandorica Opens (TV story)"]) River Song claimed and demonstrated on numerous occasions that she knew the Doctor's secret real name. (TV: Forest of the Dead [+]Loading...["Forest of the Dead (TV story)"], The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"], etc.)

However, the Seventh Doctor would later claim that "Theta Sigma" was his "nickname at college" to the coincidentally-named Trevor Sigma. (TV: The Happiness Patrol [+]Loading...["The Happiness Patrol (TV story)"]) The Ninth Doctor would later reiterate this in a duel with the Grimminy-Grew to guess the other's true name, saying that "old school nicknames don't count". (AUDIO: Station to Station [+]Loading...["Station to Station (audio story)"])

In one account, the Doctor considered it a "Time Lord coding", which he couldn't "bear [to be] addressed as". (PROSE: Doctor Who and the Armageddon Factor [+]Loading...["Doctor Who and the Armageddon Factor (novelisation)"]) It identified him uniquely amongst the Time Lords and was not to be spoken outside of the Academy. (PROSE: Falls the Shadow [+]Loading...["Falls the Shadow (novel)"]) According to the author of The Time Lord Letters, a historical document compiling writings by and concerning the Doctor, "Theta Sigma" was also their Academy Student Identification Code. (PROSE The Time Lord Letters [+]Loading...["The Time Lord Letters (novel)"])

When the Doctor's final incarnation permanently died during the first battle of the War in Heaven, his coffin had two Greek letters on it; one of these was "Sigma". (PROSE: Alien Bodies [+]Loading...["Alien Bodies (novel)"])

Commonly used aliases[[edit] | [edit source]]

John Smith[[edit] | [edit source]]

John Smith was an alias the Doctor frequently used on Earth and around humans when a "standard" name was needed, with the Eighth Doctor noting it was "the nom de guerre [he] seem[ed] to keep ending up with". (PROSE: Alien Bodies [+]Loading...["Alien Bodies (novel)"]) It was often preceded by the title "Doctor", though not always — for example, when he was undercover as a teacher at a school or a patient in a hospital. (TV: School Reunion [+]Loading...["School Reunion (TV story)"], Smith and Jones [+]Loading...["Smith and Jones (TV story)"]) As "John Smith" was considered a generic name in some Earth cultures, the Doctor's use of the alias was occasionally treated with scepticism. (TV: Midnight [+]Loading...["Midnight (TV story)"])

The First Doctor used a library card with the name Dr J. Smith while living at 76 Totter's Lane, (TV: The Vampires of Venice [+]Loading...["The Vampires of Venice (TV story)"]) as well as for identification when renting the junkyard. (PROSE: The Rag & Bone Man's Story [+]Loading...["The Rag & Bone Man's Story (short story)"]) The inspiration for the alias was John Smith of John Smith and the Common Men, with which he was familiar through Susan. (PROSE: The Witch Hunters [+]Loading...["The Witch Hunters (novel)"])

In their second incarnation, the name was independently used by his companion Jamie McCrimmon while the Doctor was being treated for a concussion, as he saw it being used as a brand name on a metal container. (TV: The Wheel in Space [+]Loading...["The Wheel in Space (TV story)"]) The Doctor himself used the alias when being interrogated by a German soldier. (TV: The War Games [+]Loading...["The War Games (TV story)"]) Likewise, Chang Lee chose to register the name for the Seventh Doctor while he was en route to get his bullet wounds healed. (TV: Doctor Who [+]Loading...["Doctor Who (TV story)"])

The Doctor adopted the name on a semi-regular basis during their third incarnation while exiled on Earth, when he served as unpaid scientific advisor to UNIT. (TV: Spearhead from Space [+]Loading...["Spearhead from Space (TV story)"], Inferno [+]Loading...["Inferno (TV story)"], The Time Warrior [+]Loading...["The Time Warrior (TV story)"]) The UNIT files referred to him as "Dr. J.S.". (AUDIO: Tales from the Vault [+]Loading...["Tales from the Vault (audio story)"])

The Doctor twice changed himself into a human who used the name John Smith. This occurred in their seventh incarnation, (PROSE: Human Nature [+]Loading...["Human Nature (novel)"]) and in their tenth incarnation. (TV: Human Nature [+]Loading...["Human Nature (TV story)"])

Often, the Doctor would use variations of the name, like the online handle "jsmith", jsmith8", (PROSE: Blue Box [+]Loading...["Blue Box (novel)"], Lonely [+]Loading...["Lonely (short story)"]) the French variation "Jean Forgeron", (COMIC: The Forgotten [+]Loading...["The Forgotten (comic story)"]) or the German translation "Johann Schmidt". (PROSE: The Shadow in the Glass [+]Loading...["The Shadow in the Glass (novel)"]; AUDIO: Storm Warning [+]Loading...["Storm Warning (audio story)"])

The Thirteenth Doctor once made use of a variant, "Jane Smith", while hiding her true identity from Martha Jones. (COMIC: A Little Help from My Friends [+]Loading...["A Little Help from My Friends (comic story)"])

By one account, "John Smith" was the name by which the Meta-Crisis Tenth Doctor chose to go upon settling down with Rose Tyler. (COMIC: Empire of the Wolf [+]Loading...["Empire of the Wolf (comic story)"])

The Tenth Doctor attempted to use this alias when he met the Fourth Doctor. However, he opted out of the second half and instead used Rose's last name, ending up with "John Tyler" instead. (AUDIO: Out of Time [+]Loading...["Out of Time (audio story)"])

The Oncoming Storm[[edit] | [edit source]]

Main article: The Oncoming Storm

The Doctor was referred to as "the Oncoming Storm" by the Draconians, (PROSE: Love and War [+]Loading...["Love and War (novel)"]) himself (PROSE: Vampire Science [+]Loading...["Vampire Science (novel)"]) and in "the ancient legends of the Dalek homeworld". (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) In Draconian, the title was pronounced "Karshtakavaar". (PROSE: Love and War [+]Loading...["Love and War (novel)"]) After being told of the title by the Ninth Doctor, (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) Rose Tyler called the Tenth Doctor by the "Oncoming Storm" when she and Mickey Smith were being prepared for dissection by the Clockwork Droids. (TV: The Girl in the Fireplace [+]Loading...["The Girl in the Fireplace (TV story)"])

The Tenth Doctor later introduced himself as the "Oncoming Storm" to a Dalek aboard of the Wayfarer, (PROSE: Prisoner of the Daleks [+]Loading...["Prisoner of the Daleks (novel)"]) and referred to the title when confronting a rabbit he thought was a Zygon. (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"])

The Eleventh Doctor began calling himself the "Oncoming Storm" when he misinterpreted Sean's request to help the King's Arms football team "annihilate" another team at a match. (TV: The Lodger [+]Loading...["The Lodger (TV story)"]) He later referred to the title when the Daleks forgot him. (TV: Asylum of the Daleks [+]Loading...["Asylum of the Daleks (TV story)"])

Destroyer of Worlds[[edit] | [edit source]]

As early as their second incarnation, the Doctor knew that the Daleks had also given them the epithet "Ka Faraq Gatri", (COMIC: Bringer of Darkness [+]Loading...["Bringer of Darkness (comic story)"]) which translated as "Destroyer of Worlds". (PROSE: Timewyrm: Revelation [+]Loading...["Timewyrm: Revelation (novel)"]) or possibly, "Nice guy, if you're a biped". (PROSE: Continuity Errors [+]Loading...["Continuity Errors (short story)"]) He had been awarded the name upon orchestrating the destruction of the Dalek home planet Skaro in his seventh incarnation, (TV: Remembrance of the Daleks [+]Loading...["Remembrance of the Daleks (TV story)"]) though the Daleks also used it prior to Skaro's destruction.
