Terileptil
Terileptils were a space-faring reptilian species, known for a love of art and beauty, matched only by their love of war.
Biology[[edit]]
Terileptils were reptilian humanoids, but also had fish-like qualities. Each Terileptil seemed to be of primarily one colour — for example, green, blue or red — but some of their scales and ruffles had variations in hue.
Terileptils breathed through gills on the side of the head, their hands and feet were like flippers, and their wide mouths were full of pointy teeth. They breathed soliton gas. (TV: The Visitation)
Technology[[edit]]
Terileptils had a highly sophisticated technology. Dependent on soliton gas, they perfected atmospheric processors which could synthesise and release the gas into the immediate area, allowing them to function in alien atmospheres lacking this vital component.
They were familiar with the use of Vintaric crystals as a means of artificial lighting, and holographic energy barriers. Terileptilan technology made heavy use of polygrite and highly charged power packs. They made frequent use of androids as guards, soldiers, and servitors. (TV: The Visitation)
Culture[[edit]]
The Terileptils placed great value on beauty, using aesthetically pleasing designs even in weaponry. Even the Terileptilan language reflected the artistic and scientific sophistication of this species; to the untrained eye Terileptilan script looked very much like mathematical formulas. As a part of this highly refined culture, the Terileptils esteemed certain vocations, such as mime and circus clown. They considered war an honourable activity and that it stood side by side with art and beauty.
Terileptils were allied with the inhabitants of the planet Hakol in the Rifta system, for whom they mined tinclavic, which was found on the planet Raaga. Condemned criminals were conscripted to mine this mineral, overseen by android guards and wearing control bracelets. Severe facial scarring was a common feature of these conscripts, possibly due to the toxic nature of raw tinclavic ore. (TV: The Visitation)
History[[edit]]
As early as Earth's late Middle Ages, Terileptils mined tinclavic for the people of Hakol. A psychic probe from Hakol landed on Earth at this time, becoming briefly active in the year 1643 and again in 1984. (TV: The Awakening)
In 1666, the Fifth Doctor found a small group of Terileptil criminals who had escaped from the penal colony on Raaga. They had somehow managed to override their control bracelets, reprogram an android guard to help them, and steal a ship. They were caught in an asteroid storm crossing through Earth's planetary system. The ship's escape pod crashed outside a small village near the future location of Heathrow Airport, with only four Terileptils surviving the crash. The Doctor could not return the creatures to their home planet, because Terileptil law stated that imprisonment on Raaga was for life. Plague was already raging in London, and the three remaining Terileptils began to genetically augment the plague bacteria, plotting to eradicate humanity and seize control of the planet.
Their plot failed when the Doctor and his companions, along with Richard Mace, fought them in a bakery on London's Pudding Lane, and a burning torch dropped during the scuffle, together with an overloaded Terileptil hand weapon, resulted in the Great Fire of London, which killed the Terileptils and destroyed their augmented plague bacteria.

In the 1970s, Torchwood Los Angeles successfully dealt with a Terileptil spaceship, thanks to the work of Gabriella Martinez. (AUDIO: The Dollhouse)
After Sutekh's Death Wave in 2024, (TV: Empire of Death [+]Loading...["Empire of Death (TV story)"]) the Fifteenth Doctor noted the Terileptil as one of the threats which could return to Earth in his contributions to UNIT's Gold Archive. Giving their chances of return as 7/10, he warned that there could be other visitations if Earth was near the path of a Terileptil spaceway. (PROSE: Watch Out... Who's About?

On 12 August 2630, the Terileptils conquered Tivoli, which was previously under Kraal control. They lost it to the Vinvocci on 17 September 2721; following their victory, the Vinvocci exiled the surviving Terileptils. (PROSE: Time Traveller's Diary)
In the mid 34th century, the Adjudicator Terrell and the Master destroyed the Terileptil homeworld using the Darkheart device. Aside from individual Terileptils who may have been elsewhere in the galaxy when this occurred, the species was wiped out. This act ended an interplanetary civilisation more than two thousand years old and was also one of the final steps in the Master's descent into darkness. (PROSE: The Dark Path)
The Terileptils were among the races who joined the Pandorica Alliance. They travelled to 102 Stonehenge and helped imprison the Eleventh Doctor in the Pandorica in order to save the universe. (TV: The Pandorica Opens)
Undated events[[edit]]
At some point, the Terileptils conquered Tivoli, like many species before and after them. (PROSE: Time Traveller's Diary)
At some point in their history, the Terileptils went to war with the Torodon. (PROSE: Hunter's Moon)
Terileptils were present during the Siege of Trenzalore. They either retreated or died in the fighting which took place after the New Dalek Paradigm broke through the Papal Mainframe's force field and plunged Trenzalore into war. Their forces either retreated or were destroyed before the final battle between the Eleventh Doctor and the Dalek Supreme's forces. (TV: The Time of the Doctor)
A Terileptil was a customer at the Intergalactic Coffee Roasting Station. (PROSE: Lights Out)
Alternate timeline[[edit]]
In an alternate timeline created by the Black Guardian where the First Doctor never left Gallifrey, and became Lord President, the Terileptils were one of many aliens that invaded Earth, and fought over the planet with other races against the Silurians and the Sea Devils. This timeline was destroyed when the Seventh Doctor retrieved the Key to Time. (COMIC: Time & Time Again)
