The Sixth Doctor was the sixth incarnation of The Doctor in the Classic Doctor Who.
Arrogant, dramatic, self-absorbed, driven and 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 empathic individual. He was also known for his clown-like multi-coloured coat and for fighting the Valeyard, an evil future regeneration or manifestation of himself.
The full circumstances leading to his regeneration are not seen on-screen, and various tie-in materials such as books and audio dramas have each had their own take on these events. On-screen, he is simply shown to have already collapsed in the TARDIS while it is under attack from a villainous Time Lord known as the Rani, and later regenerates into the Seventh Doctor.
- He appears in the Classic Who Minifigure Series.
