The '''Zygons''' were a race of metamorphic [[humanoid]]s. They originated from the planet [[Zygor]], but often tried to migrate away from it. ([[PROSE]]: ''[[The Bodysnatchers (novel)|The Bodysnatchers]]'')

== Biology ==
Zygons were solidly built [[humanoid]]s with large, cone-shaped heads. Their heads, arms and torsos were covered in suckers, and they had deeply inset faces. Zygons had maroon [[blood]] and spoke in a gurgling whisper. They were stronger than [[human]]s ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'') and longer-lived, with an average [[lifespan]] of seven hundred to one thousand [[year]]s old. ([[PROSE]]: ''[[The Bodysnatchers (novel)|The Bodysnatchers]]'') They also had an earthy, [[iron]] odour and the ability to sting people with venomous barbs on their palms. These stings could stun, maim or kill. They left large welts on the affected area. ([[PROSE]]: ''[[Doctor Who and the Loch Ness Monster (novelisation)|Doctor Who and the Loch Ness Monster]]'', ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'')

They also had the ability to transform members of other species into Zygons, with the side effect of creating a telepathic link between the new Zygon and the one that induced the change. After she was converted into such a human-Zygon hybrid, ([[HOMEVID]]: ''[[Zygon: When Being You Just Isn't Enough (home video)|Zygon: When Being You Just Isn't Enough]]'') [[Lauren Anderson|Lor Anderson]] began to emit highly unusual [[pheromone]]s which allowed [[Stacey Facade]] to trace her across [[London]] with ease after Lor tried to get away from Stacey. ([[HOMEVID]]: ''[[Lauren Anderson (home video)|Lauren Anderson]]'')

They had venom sacs located in their [[tongue]]s. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')

Young Zygons were called [[hatchling]]s and were slimy and pale with shorter limbs. Hatchlings were mute, but much faster than adults. ([[PROSE]]: ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'')

[[File:Destiny_of_the_Zygon.jpg|thumb|left|A Zygon is easily hypnotised. ([[GAME]]: ''[[Destiny of the Doctors (video game)|Destiny of the Doctors]]'')]]
Zygons had a deeply ingrained [[fear]] of [[fire]]. ([[PROSE]]: ''[[Doctor Who and the Loch Ness Monster (novelisation)|Doctor Who and the Loch Ness Monster]]'') They could be easily [[Hypnosis|hypnotised]] by a [[clock]]'s swinging pendulum. ([[GAME]]: ''[[Destiny of the Doctors (video game)|Destiny of the Doctors]]'')

Zygons were [[hermaphrodite]]s. At the start of their lives, they had an almost white colour and were more feminine and graceful, without suckers. They became [[orange (colour)|orange]]-coloured, were covered in suckers and became more stocky and masculine in appearance after being sterilised. The greatest rank a Zygon could attain was "warrior engineer". To become a warrior engineer, a Zygon must undergo sterilisation, a process which makes them more aggressive and single-minded. ([[PROSE]]: ''[[The Bodysnatchers (novel)|The Bodysnatchers]]'')

Zygons were able to produce [[electricity]] bolts from their hands that could stun humans or other Zygons or disintegrate them into piles of hair and skin. ([[TV]]: ''[[The Zygon Invasion (TV story)|The Zygon Invasion]]'') It seemed unable to have any effect on [[Time Lord]]s, however, when used on the [[Twelfth Doctor]], he was slightly phased, but otherwise unharmed. ([[TV]]: ''[[The Zygon Inversion (TV story)|The Zygon Inversion]]'')

== Technology ==
Zygon technology was partly biological, with an organic look. This was exemplified by the [[Skarasen]], a large, cybernetically enhanced creature from their homeworld. Zygons were also known to depend upon the lactic fluid of the Skarasen for their survival. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'') Their use of organic ships was well known. ([[PROSE]]: ''[[Alien Bodies (novel)|Alien Bodies]]'')

One of the most important Zygon achievements was their use of [[body-print]]s. Usually, the Zygons would capture a specimen, such as a [[human]], and put them in a special receptacle. A Zygon could then take the form of this specimen, mimicking both voice and appearance. This body-print needed to be renewed every two hours, while the prisoners were kept alive but unconscious. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'') However, in some circumstances they were able to adopt the shape of the specimen without keeping them in a receptacle, although they still needed the specimen alive. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') At some point they gained the ability to keep the shape of a deceased specimen, as long as they did not need any more information from them. They also gained the ability to forge a telepathic link with another being and take the form of a someone from their memory. ([[TV]]: ''[[The Zygon Invasion (TV story)|The Zygon Invasion]]'')

Though they generally took the forms of [[humanoid]]s, they could also mimic creatures of diverse sizes and shapes, such as [[dog]]s, [[cattle]] and [[horse]]s. ([[PROSE]]: ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'', [[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') A Zygon who was unable to transform was known as a [[Zynog]]. ([[AUDIO]]: ''[[Death in Blackpool (audio story)|Death in Blackpool]]'') If a Zygon was killed while disguised, it would remain in that form as a corpse. ([[HOMEVID]]: ''[[Zygon: When Being You Just Isn't Enough (home video)|Zygon: When Being You Just Isn't Enough]]'')

To control the Skarasen, the Zygons used [[Trilanic activator]]s. Zygons frequently used molecular dispersal to get rid of corpses. Their ships tracked the life-signs of the Zygons and would bring the corpse back to the ship if a Zygon was killed. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'', [[PROSE]]: ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'') They also made use of a type of [[nerve gas]] to render humans unconscious. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'') Another Zygon discovery was called the "amber sleep", which was a type of [[suspended animation]]. ([[PROSE]]: ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'')

Zygons used [[hologram shell]]s to mimic clothes when shapeshifting, but they could not mimic functional objects like [[inhaler]]s. ([[PROSE]]: ''[[The Day of the Doctor (novelisation)|The Day of the Doctor]]'')

== Culture ==
Zygons were divided into clans, each with a different culture. ([[AUDIO]]: ''[[The Zygon Who Fell to Earth (audio story)|The Zygon Who Fell to Earth]]'') Zygon warlords fought in elaborate shape-shifting duels using the bodies of other creatures held captive. ([[COMIC]]: ''[[Rest and Re-Creation (comic story)|Rest and Re-Creation]]'') A [[Zygon High Command]] organised [[Operation Double]] on [[Earth]] with the [[Unified Intelligence Taskforce]] before being violently overthrown and replaced by a faction of radical Zygons called [[Truth or Consequences (group)|Truth or Consequences]] which sought to usurp [[human]]ity. ([[TV]]: ''[[The Zygon Invasion (TV story)|The Zygon Invasion]]'') [[Zygon Queen]]s ruled over individual planets. ([[PROSE]]: ''[[Lords and Masters (short story)|Lords and Masters]]'')

Zygons measured distance in [[remar]]s. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'', [[PROSE]]: ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'')

Zygons were rather fond of board games and worshipped a [[God|deity]] called [[Kaatu]]. ([[PROSE]]: ''[[The Bodysnatchers (novel)|The Bodysnatchers]]'')

Zygons would sometimes use [[Hydrorc]]s as henchmen. ([[GAME]]: ''[[The Edge of Time (video game)|The Edge of Time]]'')

== History ==
=== Early history ===
[[File:Alliance of Races.jpg|thumb|The Alliance of Races. ([[COMIC]]: ''[[Gangland (comic story)|Gangland]]'')]]
The Zygons joined [[Rassilon]] in the [[Alliance of Races]] against the [[Hyperion (species)|Hyperions]]. ([[COMIC]]: ''[[The Hyperion Empire (comic story)|The Hyperion Empire]]'') After the Hyperions were defeated, the Alliance then went on to purge the universe of other threats to universal harmony, one of those threats being Count [[D'if]] of the [[Cybock Imperium]]. ([[COMIC]]: ''[[Gangland (comic story)|Gangland]]'')

=== Loss of Zygor ===
According to one account, the Zygons were originally at war with the [[Xaranti]]. During this war, both the Zygon homeworld, [[Zygor]], and the Xaranti home [[planet]]s were destroyed. ([[PROSE]]: ''[[The Bodysnatchers (novel)|The Bodysnatchers]]'') Another account given by the Zygon [[Broton]] in the [[20th century]] said his world was destroyed in a "recent catastrophe". ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'') Another account given by [[Elizabeth I]] in [[1562]] states that their planet burnt in the first days of the [[Last Great Time War]]. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') Most accounts agreed the planet was lost to the Time War. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'', [[PROSE]]: ''[[The Day of the Doctor (novelisation)|The Day of the Doctor]]'', ''[[The Whoniverse (novel)|The Whoniverse]]'')

Refugees created a refugee fleet, and the ship on [[Earth]] was contacted. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'')

=== 2nd century ===
In [[102]], the Zygons were among the races who joined the [[Pandorica Alliance]] at Stonehenge. They came to [[Stonehenge]] and helped imprison the [[Eleventh Doctor]] in the [[Pandorica]] to "save" the [[universe]]. ([[TV]]: ''[[The Pandorica Opens (TV story)|The Pandorica Opens]]'')

=== Before the 12th century ===
At some point before the [[12th century]], a Zygon ship was damaged and forced to land on [[Earth]] near [[Devil's Punchbowl]] in [[Scotland]]. They had a Skarasen with them which, though still an infant at that point, provided them with the lactic fluid they needed to survive. Over the next 400 years, people around the area turn up missing. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'')

=== 16th century ===
A rogue Zygon hive of the [[Under Wave]] was caught in a [[time eddy]], ([[PROSE]]: ''[[The Day of the Doctor (novelisation)|The Day of the Doctor]]'') and crash landed in [[1562]]. They were investigated by the [[Tenth Doctor]], with one of them impersonating [[Elizabeth I]]. After the real Elizabeth killed her impersonator, the Zygons implanted themselves into [[stasis cube]]s, planning to wait until Earth was more suitable for conquest. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')

=== 19th century ===
In the late 19th century, a Zygon became a member of a travelling freak show and later impersonated [[Queen]] [[Victoria]]. ([[AUDIO]]: ''[[The Barnacled Baby (audio story)|The Barnacled Baby]]'')

A Zygon ship was trapped under where the [[Savoy Hotel]] was. During the grand opening in [[1890]], Zygons replaced half the staff, but the [[Eleventh Doctor]], [[Amy Pond]] and [[Rory Williams]] stopped them. ([[TV]]: ''[[The Power of Three (TV story)|The Power of Three]]'')

The [[Eighth Doctor]], [[Sam Jones]] and [[George Litefoot]] encountered a group of Zygons in London in [[1894]]. ([[PROSE]]: ''[[The Bodysnatchers (novel)|The Bodysnatchers]]'')

=== 20th century ===
Another ship from Zygor arrived on [[Earth]] in [[1909]]. Though they had brought two Skarasen, their minds were damaged by the solar radiation during the destruction of Zygor. One was killed during repairs. Though the Zygons attempted to conquer Earth anyway, starvation and the Tenth Doctor forced them to abandon their plans. ([[PROSE]]: ''[[Sting of the Zygons (novel)|Sting of the Zygons]]'')

In the [[20th century]], a Zygon spaceship landed in a [[Brentford]] quarry. The Zygons of Devil's Punchbowl decided to take over [[Earth]] and physically adapt it to an environment more suited to their species. [[UNIT]] and the [[Fourth Doctor]] stopped them, freeing the Skarasen. ([[TV]]: ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'')

In [[1981]], UNIT had to deal with over a hundred Zygons who survived a previous invasion. ([[PROSE]]: ''[[The King of Terror (novel)|The King of Terror]]'')

In [[1984]], the [[Eighth Doctor]] and [[Lucie Miller]] encountered a Zygon who was impersonating [[Patricia Ryder|Lucie's aunt]]'s husband, [[Trevor (The Zygon Who Fell to Earth)|Trevor]]. After Patricia died, the Zygon assumed her form in her honour. ([[AUDIO]]: ''[[The Zygon Who Fell to Earth (audio story)|The Zygon Who Fell to Earth]]'')

In [[December]] [[1985]], a [[Zygon (Skywatch-7)|Zygon]] landed in [[Antarctica]], near UNIT [[Arctic base Skywatch-7]]. Several people stationed there were killed, but the survivors were able to drive the Zygon into the icy water where it perished. ([[COMIC]]: ''[[Skywatch-7 (comic story)|Skywatch-7]]'')

Circa [[1999]], a Zygon invasion of Earth was prevented by [[United Nations|UN]] [[military advisor]] [[Guy Dean]]. ([[AUDIO]]: ''[[Homeland (audio story)|Homeland]]'')

=== 21st century ===
[[File:Zygon When Being You Just Isn't Enough.jpg|thumb|The Zygon "[[Torlakh]]" in the early-21st century. ([[HOMEVID]]: ''[[Zygon: When Being You Just Isn't Enough (home video)|Zygon: When Being You Just Isn't Enough]]'')]]
In the late-20th and early [[21st century|21st centuries]], the Zygons [[Torlakh]] and [[Kritakh]] were deployed on Earth, where they took the forms of [[Bob Calhoun]] and [[Michael Kirkwood]] respectively. They then began to go to [[nuclear power plant]]s around the world, so that 70 years later the planet would be more suited to Zygons and they could hand the planet over to a Zygon invasion force. The plan backfired when Kritakh began to believe he was [[Michael Kirkwood]], and began to see a [[psychiatrist]] about his dreams of being a Zygon. His doctor, [[Lauren Anderson]], was turned into a Zygon by Torlakh, and she went to see him again. However, she decided to help Michael stop Torlakh. They put the real [[Bob Calhoun]] and [[Michael Kirkwood]] in the hospital, and Torlakh left to continue his life on the run. Lauren, however, also was forced to live on the run, when Torlakh killed many of her co-workers at the hospital. She left, but not until after she killed Torlakh while he was in her form. ([[HOMEVID]]: ''[[Zygon: When Being You Just Isn't Enough (home video)|Zygon: When Being You Just Isn't Enough]]'')

In [[2008]], the [[Eighth Doctor]] and [[Lucie Miller]] again encountered the Zygon who was impersonating [[Patricia Ryder]]. ([[AUDIO]]: ''[[Death in Blackpool (audio story)|Death in Blackpool]]'')

In [[2013]], the Zygons that were frozen in [[1562]] woke from their stasis cubes and infiltrated UNIT, gaining access to the technology in the [[Black Archive]]. To prevent them using the technology, [[Kate Stewart]] activated the countdown to a [[nuclear warhead]] beneath the Archive. Before the countdown reached zero, the Tenth, Eleventh and [[War Doctor]]s temporarily erased the memories of the original Kate, [[Petronella Osgood|Osgood]] and [[McGillop]], as well as their Zygon impersonators causing them to forget which ones were human and which were Zygon. Both Kates cancelled the detonation, and the humans and Zygons were able to create a peace treaty between them whereupon the Zygons would [[hider|live in secret]] on Earth. When no one was looking the [[Zygon Osgood|Zygon copy of Osgood]] slipped the original's [[inhaler]] back to her. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')

[[2015|Two years later]], [[Truth or Consequences (group)|a rebel faction]] of Zygons, led by [[Bonnie (The Zygon Invasion)|Bonnie]], began to undermine the ceasefire. Bonnie had taken the form of [[Clara Oswald]], and was determined to expose the 20 million Zygons living on Earth and find a land of their own, ([[TV]]: ''[[The Zygon Invasion (TV story)|The Zygon Invasion]]'') but this threat was defused by a contingency developed by the [[Twelfth Doctor]] involving two [[Osgood Box]]es. With Bonnie taking the place of the Osgood who had been killed by [[Missy]], the Zygon-human peace remained stable. ([[TV]]: ''[[The Zygon Inversion (TV story)|The Zygon Inversion]]'') In [[2019]], the [[Box (When to Die)|Box]] knew there still was a large "shapeshifter community" present on Earth. ([[PROSE]]: ''[[Out of the Box (short story)|Out of the Box]]'')

=== 22nd century ===
150 years after Kritakh and Torlakh were brought to Earth, the Zygon invasion force was still due to arrive on Earth. ([[HOMEVID]]: ''[[Zygon: When Being You Just Isn't Enough (home video)|Zygon: When Being You Just Isn't Enough]]'')

=== 28th century ===
In [[2765]], Zygons attempted to melt [[Earth]]'s polar ice caps but were stopped by [[INITEC]]'s [[Vigilante laser defence satellite]]s. ([[PROSE]]: ''[[Original Sin (novel)|Original Sin]]'')

=== 36th century ===
Circa the early [[36th century]], a group of Zygons on [[Ganta 4]] infiltrated the [[New Eden (colony)|New Eden]] colony so that they could use their spaceship to evade Earth security and invade humanity's homeworld. The plan was defeated by colonist [[Christopher Shaw]], and the Zygons were all killed. ([[AUDIO]]: ''[[Absolution (BBV audio story)|Absolution]]'')

=== Undated events ===
On [[Shontaa]], the Zygon warlords [[Anktra]] and [[Kestral (Rest and Re-Creation)|Kestral]] fought a duel using a variety of host bodies. The [[Fourth Doctor]] and [[Leela]] ended the duel by freeing the host creatures which the Zygons were mimicking. ([[COMIC]]: ''[[Rest and Re-Creation (comic story)|Rest and Re-Creation]]'')

{{Ainley|c}}, using the power of the planet [[Siralos]], transported some Zygons and other adversaries to [[the Doctor's TARDIS]] to stop [[the Graak]] from saving the imprisoned seven incarnations of [[the Doctor]]. ([[GAME]]: ''[[Destiny of the Doctors (video game)|Destiny of the Doctors]]'')

The [[Divine Empress]] had Zygons under her command. ([[PROSE]]: ''[[Genocide (novel)|Genocide]]'')

[[River Song]] once angered Zygons by greeting them with, "What's up, suckers?" ([[GAME]]: ''[[The Eternity Clock (video game)|The Eternity Clock]]'')

A yellow Zygon was present at [[Garage 10]]. ([[COMIC]]: ''[[The Ministry of Time (comic story)|The Ministry of Time]]'')

The [[Ninth Doctor]] defeated a Zygon who took the form of [[Rose (Little Rose Riding Hood)|Rose]]'s [[Rose's grandmother|grandmother]]. He then broke it's body-print technology. ([[PROSE]]: ''[[Little Rose Riding Hood (short story)|Little Rose Riding Hood]]'')

=== Alternate timelines ===
In an [[Alternate timeline (Time & Time Again)|alternate timeline]] created by the [[Black Guardian]] where the [[First Doctor]] remained on [[Gallifrey]], and became [[Lord President]], the Zygons were one of many aliens that invaded [[Earth]], and fought over the planet with other races against the [[Silurian]]s and [[Sea Devil]]s. This timeline was negated when the [[Seventh Doctor]] retrieved the [[Key to Time]]. ([[COMIC]]: ''[[Time & Time Again (comic story)|Time & Time Again]]'')

In an [[parallel universe|alternate dimension]] in which [[the Doctor]]'s adventures existed as a fictional TV show called ''[[Doctor Who (The Girl Who Loved Doctor Who)|Doctor Who]]'', a fan dressed as a Zygon was present at a ''Doctor Who'' convention which the [[Eleventh Doctor]] visited with [[Ally (The Girl Who Loved Doctor Who)|Ally]] in [[2013]]. ([[COMIC]]: ''[[The Girl Who Loved Doctor Who (comic story)|The Girl Who Loved Doctor Who]]'')

== References ==
The [[Fourth Doctor]] knew that, if the Zygons managed to acquire a [[TARDIS Instruction Manual]], they would bring forth a great wave of destruction upon the universe. ([[PROSE]]: ''[[The Pirate Planet (novelisation)|The Pirate Planet]]'')

When reunited with the [[Fifth Doctor]], [[Alistair Gordon Lethbridge-Stewart|the Brigadier]] remembered the Zygons among the adversaries he had fought as head of [[UNIT]]. ([[TV]]: ''[[Mawdryn Undead (TV story)|Mawdryn Undead]]'') While helping [[Sarah Jane Smith]] defeat [[Mrs Wormwood]], he once again listed Zygons as an enemy he had fought. ([[TV]]: ''[[Enemy of the Bane (TV story)|Enemy of the Bane]]'')

The [[Seventh Doctor]] used "the Zygon gambit with the Loch Ness Monster" as an example to [[Ace]] of the [[alien invasion]]s that humans had managed to rationalise away or forget. ([[TV]]: ''[[Remembrance of the Daleks (TV story)|Remembrance of the Daleks]]'') The incident had also been covered up as an inflatable fake monster, with the organisers of the [[International Energy Conference]] claiming protesters had used it to draw attention to the impact [[North Sea Oil]] had on nature, specifically to the [[Loch Ness]] countryside. ([[PROSE]]: ''[[The Secret Lives of Monsters (novel)|The Secret Lives of Monsters]]'')

The Seventh Doctor said that when he felt depressed, he would make [[clay]] models of Zygons to cheer himself up. ([[PROSE]]: ''[[Human Nature (novel)|Human Nature]]'')

In the [[video game]] ''[[Happy Deathday]]'', played by [[Izzy Sinclair]] on the [[Time-Space Visualiser]], a pair of Zygons were among a host of "every single [[enemy]]" that [[the Doctor]] had ever [[defeat]]ed, who were assembled by the [[Beige Guardian]] and pitted against the Doctor's first eight [[incarnation]]s. ([[COMIC]]: ''[[Happy Deathday (comic story)|Happy Deathday]]'')

When the [[telepathic]] [[Emily Fairfax]] read the mind of the [[Hypothetical Gentleman]], a Zygon was among the images she saw. ([[COMIC]]: ''[[Hypothetical Gentleman (comic story)|Hypothetical Gentleman]]'')

Following the [[3W Institute Affair]], [[Missy]] considered a "team up" with the Zygons, among others. ([[PROSE]]: ''[[The Secret Diary of the Master (short story)|The Secret Diary of the Master]]'')

[[Ashildr|Mayor Me]] considered her hidden [[Trap Street, London|trap street]], which had existed in [[London]] for at least a century prior to [[Operation Double]], to be a more favourable way of housing [[alien]]s on [[Earth]] as opposed to the settling of the Zygons amongst humanity. Later, in a desperate gambit to prevent [[Clara Oswald]] from sacrificing herself, the [[Twelfth Doctor]] threatened Me to relinquish the [[Quantum Shade]] on Clara or he would expose her trap street and bring UNIT and the Zygons down on it. ([[TV]]: ''[[Face the Raven (TV story)|Face the Raven]]'') The protection granted to Zygons on Earth was exploited by other shapeshifters such as [[Ballon]], a [[Lorr]], who posed as a Zygon in order to avoid detection by UNIT only to be captured by [[the Governors]]. ([[TV]]: ''[[The Metaphysical Engine, or What Quill Did (TV story)|The Metaphysical Engine, or What Quill Did]]'')

According to the [[Thirteenth Doctor]], her [[Granny Five]] claimed that [[Granny Two]] was a secret agent for the Zygons. ([[TV]]: ''[[It Takes You Away (TV story)|It Takes You Away]]'')

By the [[67th century]], the Zygons were recorded in the [[vid-briefing]] series ''[[Perils of the Constant Division]]''. ([[TV]]: ''[[The Tsuranga Conundrum (TV story)|The Tsuranga Conundrum]]'')

== Behind the scenes ==
===''Doctor Who: Legacy''===
Zygons are used as both allies and enemies in the ''[[Legacy (video game)|Doctor Who: Legacy]]'' mobile game. In addition, many enemies are created to be Zygons taking the form of an ally.

In the storyline, numerous Zygons are recruited to serve as [[reinforcement]]s by [[time travel]]ling [[Sontaran]]s to stop [[the Doctor]]s and their [[companion]]s from interfering as they wage [[war]] throughout [[history]]. Fearing their imminent demise, they quickly launched ships with thousands of "brave warriors" directly at [[Sontar]]. In the chaos every Zygon warrior died save for five who used their [[body-print]] technology to infiltrate the [[Sontaran High Command]] and initiate a treaty between the two races, the Sontarans agreeing to shield the Zygons from the changes to time which were ripping [[the universe]] while the Zygons help prepare for a "glorious future where the Zygon and Sontaran empires control the universe together". Acting in the interests of survival, the Zygons accept the [[Eighth Doctor]]'s assessment that they are [[Mercenary|mercenaries]] and demonstrate awareness of the fates of forces such as the [[Cybermen]], the [[Nestene Consciousness]] and the [[Slitheen family]].

After the Sontarans are overrun by {{Simm}}'s [[Toclafane]], the [[First Doctor]] reports that the Zygons have fled, vanishing into whatever population centres still existed in the timeline.
