The Doctor (Time Lord)

The Doctor was a fictional character of the science fiction television series Doctor Who from the 20th and 21st centuries.

He was a renegade Time Lord from the planet Gallifrey, who traveled through time and space in his TARDIS. The Doctor could survive fatal injuries through a process known as regeneration, which also changed his physical appearance and personality. This characteristic allowed for several actors to portray the character over the long course of the series.

He often used a sonic screwdriver.


 * It should be noted that the fictional Doctor has yet not been mentioned by name within Trek sources, and the above information comes from real-world sources.

The television character
In 2275, Jerry Freeman, Nyota Uhura and Harb Tanzer of the USS Enterprise (NCC-1701) converted an episode of a 20th century Earth television series into a three-dimensional hologram in the recreation room. They and James T. Kirk saw a time machine materialize and the main character step out and ask if he was in Heathrow.


 * The scene never appeared in real-world Doctor Who suggesting this series progressed differently.

The time traveler

 * The Doctor has been referenced or made cameo appearances in several licensed works, though unnamed. These are collected here for reference, though may not necessarily be the same person given the limited descriptions.

An unidentified time traveler fitting the Doctor's description has appeared several times. He potentially came from a stagnant civilization that had mastered time travel in the Kasteroborous galaxy.


 * In Doctor Who, Gallifrey is located in the Kasterborous constellation, though this connection had not been made in a Star Trek source.

A small man in a scruffy frock coat with a flute (resembling the Second Doctor visited a gambling hall on Montgomery Street, San Francisco, on Earth in 1867. He left with a young woman who'd been the topic of an argument between two trail-hands and a gambler.

Cervantes Quinn once stole a sonic screwdriver from "a rather daft chap" on Barolia, prior to 2265.

A tall, curly-haired man in eccentric dress (resembling the Fourth Doctor) visited the Wonder Bar on Starbase 12 in 2267. He left with a young woman who'd been the topic of an argument between a spice-smuggler and a pair of migrant fleet pilots.

A TARDIS resembling the Doctor's, in the guise of London police telephone box, appeared in the trophy room of Emperor Vandar in an alternate reality and in the Eridian Vault in 2269.


 * The upcoming miniseries will be a crossover between Doctor Who and Star Trek: The Next Generation. This will likely feature the Doctor and his TARDIS making a real appearance within the Star Trek universe.
