Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.



Biodata — short for biographic data, (PROSE: Alien Bodies) also spelt Biog Data (PROSE: A Brief History of Time Lords) or called life-gifts (PROSE: Newtons Sleep) or aatma (PROSE: Dharmayuddha) — contained information on a person's history and timeline, analogous to temporal DNA. (PROSE: Alien Bodies) The First Doctor described a person's biodata as their space-time event. (AUDIO: The Vardan Invasion of Mirth) If an individual's biodata could be manipulated, their entire time stream could be altered. (PROSE: Alien Bodies) A biodata signature was also referred to as an "artron imprint." (AUDIO: The Inquiry)

A biodata extract could be used to give a biodata projection. Once seen, that future became a fixed point in that individual's personal timeline. (AUDIO: The Vardan Invasion of Mirth)

On Gallifrey, extracts of every Time Lord's biodata were stored in 'biogs' (short for biodata log). Excitonics was the technology underlying its circuitry. The Decayed Master was able to gain access to the Fourth Doctor's biodata extract to summon him to Gallifrey. (TV: The Deadly Assassin) Certain artefacts could also alter biodata, such as the Sash of Rassilon and other Presidential artefacts changing the biodata of Time Lord presidents to allow them to access certain secrets that only the President was authorised to use (PROSE: Alien Bodies)

Members of the Great Houses had their biodata linked to their Homeworld, while the biodata from their entire history was sewn into the structure of the Spiral Politic itself. (PROSE: The Book of the War) A Time Lord's biodata link to Gallifrey was represented by a second heart (PROSE: The Adventuress of Henrietta Street, Camera Obscura), which some Oldblood Time Lords grew after their first regeneration (PROSE: The Man in the Velvet Mask) while Newblood Time Lords were loomed with them. (PROSE: Christmas on a Rational Planet)

Omega used the biodata of the Fifth Doctor in an attempt to escape the anti-matter universe. (TV: Arc of Infinity)

Faction Paradox used biodata in their rituals. They used a biodata extractor to take biodata from a subject, though blood would work, since it contained biodata. (PROSE: Alien Bodies)

Griffin was able to alter the Eighth Doctor's biodata to remove his ability to perceive the colour violet. Griffin also prepared a pair of formulas that would alter the complex biodata histories of the Doctor and Samantha Jones into a single more predictable timeline, but the Doctor and Sam destroyed these samples before they were forced to drink them. The Doctor later claimed to have fixed Griffin's 'tweak' regarding his ability to see violet, (PROSE: Unnatural History) though much later in his life, while suffering from amnesia with no memory of these events, he again professed his blindness to this shade. (PROSE: To the Slaughter)

Compassion evolved into a type 102 TARDIS after the Doctor added a filter to the receiver she had been given by the Remote (PROSE: The Blue Angel). The filter was intended to prevent Compassion becoming susceptible to any random signals she would pick up in her travels with the Doctor, but the filter resulted in Compassion's biodata becoming warped as the filter's link to the TARDIS resulted in Compassion's receiver processing signals from the TARDIS as Block Transfer Computations, altering her physiology. (PROSE: The Shadows of Avalon)

The Faction had developed biodata viruses that could infect potential Faction members to convert them to share the Faction's beliefs and abilities. Normally these viruses were too weak to infect Time Lords, but the virus was able to infect the Third Doctor when his history was changed and he was killed on Dust, resulting in him regenerating ahead of schedule and the virus infecting him while his immune system was in chaos during the change. (PROSE: Interference) The Doctor believed that he could cure himself of the virus with access to samples of his uncontaminated biodata, but he never had a chance to test this theory, and was only able to save himself by averting the timeline where he was infected in the first place. (PROSE: The Ancestor Cell)

Thalia was an expert in the field of biodata. (PROSE: Arc of Infinity)

Braxiatel had a Biodata Archive, with the biodata of every Time Lord in every regeneration, so that Gallifrey could be rebuilt should it fall to the Dogma Virus. (AUDIO: Panacea)

The Eleven used a biodata disseminator to kill Dita, Landa or Shimona. (AUDIO: The Eleven)

The Devolver reverted species to a single-celled form via a sample of their biodata. (AUDIO: The Enemy of My Enemy)
