The Sixth Doctor - Colin Baker (1984

Colin Baker was very enthusiastic but he had a rough time as the Doctor. After his first full season Doctor Who was delayed 18 months. Then they brought it back and fired Colin Baker, he is the only Doctor to get fired. For many he is the worst Doctor and his first episode, the Twin Dilemma, is considered by many to be the worst Doctor Who episode ever (and it came after the best episode ever).
