The adventures in time and space of the Doctor, a Time Lord who changes appearance and personality by regenerating when near death, and is joined by companions in battles against aliens and other megalomaniacs.
In the serial Doctor Who: The Deadly Assassin: Part One (1976), it was established that the Doctor and the Time Lords have only 12 regenerations. However, it was also established in the 20th anniversary special, Doctor Who: The Five Doctors (1983), that the High Council of Time Lords can offer a new life cycle of regenerations. (In the 50th anniversary special, Matt Smith's Doctor was "gifted" an unspecified amount of regeneration "energy", and therefore an unknown number, as of late 2018, of further regenerations in the new cycle, starting with Peter Capaldi becoming Jodie Whitaker's Doctor regeneration).
You are indeed a worthy opponent, Doctor. It's what gives your destruction its... piquancy.
The tradition of showing The Doctor's face in the opening titles was not introduced until Patrick Troughton's tenure with the program was under way. During Jon Pertwee's era, the producers experimented with changing the opening credits and music. One of the rejected opening credits was accidentally included on some prints of the story "Carnival of Monsters" that were broadcast overseas.
The first episode of Doctor Who to air in the UK was in fact the second episode ever made. Like Star Trek, a first pilot was filmed but never shown. This version is fairly similar to the aired version, but contains a number of subtle differences. In particular, a different version of the theme tune is used, and the Doctor comes across as more of an anti-hero in this version.
