The Sixth Doctor

The Sixth Doctor, portrayed by Colin Baker (1984-1987)

Bumptious, melodramatic, and above all stubborn, the Sixth Doctor instantly believed himself superior to almost anyone he encountered. He would often browbeat others into submission with his savage wit and his grammarian’s interest in language. Even so, his mercurial and flippant tendencies did not define the true heart of his persona. Beneath his thunderous and turbulent exterior, he was quite the opposite: a passionate, warm, virtuous and empathetic individual.

He was profoundly difficult with his first companion, Peri Brown. During the early hours after his regeneration he physically assaulted her due to post-regenerative paranoia. It took considerable time for himself and Peri to stop bickering and speak together on amiable terms, but the Sixth Doctor eventually became someone she could rely upon.

A dominant feature of his life was yet another Time Lord trial, which turned out to be an elaborate ruse. He later found himself in a reverse situation where he became the prosecutor against the Valeyard, the malicious being that had framed him in an attempt to steal his regenerations. He discovered that the Valeyard’s dubious existence was somehow tied to his own and took shape from his inherently darker characteristics.

Long after this trial, the Doctor was slowly manipulated by the Valeyard, the malicious being that had framed him in an attempt to steal his regenerations. Forced to arrange his own demise to prevent this genocidal plot, the Sixth Doctor was influenced by his next incarnation into inadvertently crossing paths with the Rani, who dealt him a fatal blow. He regenerated, putting his future in the hands of his successor.
