The Doctor

"The Doctor", a title which embodied their promise to the universe, was the main alias used by a mysterious renegade Time Lord from Gallifrey who travelled through time and space with various companions in an obsolete and "borrowed" Type 40 TARDIS. They were the universe's "greatest defender", having saved the cosmos thousands of times throughout a long life, becoming a great legend across the universe. Though largely a believer in non-violent conflict resolution, they were, when absolutely necessary, a great warrior.

The Doctor's personal history was constantly changing and contradicting itself. Their early life and their true species were matters of much contention, in part due to shifting timelines. The Doctor's own memories were unclear regarding their early life and origins, and several accounts suggested that they had non-Gallifreyan origins.

Many details of Doctor's early life were unclear, with numerous sources describing contradicting accounts. The exact reasons for the Doctor leaving Gallifrey remain unknown and there is much evidence to suggest that the Doctor had a secret past on Gallifrey.

From the latter years of their first incarnation onward, the Doctor had a pronounced affinity for Earth and the human race. After departing Gallifrey, they voluntarily chose to spend time on the planet, choosing it as the place of their exile during most of their third incarnation. They favoured Great Britain as a frequently visited location, taking most of their companions from there.

Though taste in fashion did change with each Doctor, one thing that was an almost constant were jackets, either as part of an outfit or an extra like a trench coat.
