This is a round-up of all my posts about the Sixth Doctor, played by Colin Baker.
The Twin Dilemma
Attack of the Cybermen
Vengeance on Varos
Mark of the Rani
The Two Doctors
Timelash
Revelation of the Daleks
Trial of a Time Lord
And of course, Colin Baker also appears briefly at the end of “The Caves of Androzani” as the Doctor, and also in “Arc of Infinity” he played the character of Maxil.
