Doctor Who: The War Doctor, Explained

Game Rant

The War Doctor appeared in Doctor Who's 50th Anniversary special, and was depicted as someone aged and weary.

The War Doctor, played by John Hurt, is a significant character in Doctor Who despite not having an official number like the other Doctors.
The War Doctor existed during the Time War and was a battle-hardened warrior who made tough decisions, including committing double genocide, to end the conflict between the Time Lords and the Daleks.
In "The Day of the Doctor," it is revealed that the War Doctor actually saved the Time Lords and caused the Daleks to wipe themselves out. He reclaimed the title of The Doctor, but his memory of this event was erased. Some viewers argue that the War Doctor deserves recognition and a title despite his actions.
