The Doctor

"The Doctor" AKA "Doctor Who", was a renegade Time Lord from Gallifrey who traveled through time and space with various companions in his obsolete and "borrowed" Type 40 TARDIS. He was the universe's "greatest defender", having saved the cosmos thousands of times throughout his long life, becoming a great legend across the whole universe.

The Doctor also happens to be an unlikely hero of the Christmas Episodes that aired on the BBC every Christmas Season.
