Burner Doctor

The Burner Doctor was a version of the Doctor who existed in an alternative timeline.

Biography
During his early life, this version of the Doctor had to leave Gallifrey after challenging the Time Lords' temporal intervention policy. A non-interventionist, the Doctor believed the Time Lords should be observing the universe's timelines, not actively meddling in them, and like all non-interventionists, the Doctor found himself ostracised by the other Time Lords. He faced erasure from the timeline by his brother Braxiatel, who was the President's Lord Burner. The Doctor killed Braxiatel instead, adopted "the Doctor" as a new title, stole a TARDIS, and fled Gallifrey to challenge the Time Lords' supposed right to rewrite history. Once he had escaped Gallifrey, the Doctor tried to undo the damage caused by the Time Lords. (AUDIO: Disassembled)

By an incarnation resembling the N-Space's Sixth Doctor, the Doctor was captured by the Time Lords and put on trial. The outcome resulted in his reintegration into Time Lord society. By the time that Lady President Romana came to power, the Doctor had adopted the title "Lord Burner" and the role of the President's personal temporal assassin who "burned" people from history, a role previously held by Braxiatel in both the proper and alternative timelines. Once he held the title, the Doctor turned his back on his previous beliefs, saying casually to others his attempts were a tale told by an idiot.

After meeting an alternative version of his brother, Lord Burner attempted to assassinate him on the Axis. During the fight, they fell into one of the Axis' portals with no set coordinates. Braxiatel found his way back to the proper timeline. (AUDIO: Disassembled)

Behind the scenes
The idea for the Burner Doctor was to explore a Doctor who had been placed on trial by his people, as in The War Games, but with different results by Time Lords with very different values. (BFX: Gallifrey IV)
