Peter Davison was the fifth Doctor. There was some speculation about who would succeed Tom Baker, suggestions were even made that it could be a woman who took on the part! Peter Davison became a more youthful, milder and sometimes less confident Doctor and based his attitude on William Hartnell's portrayal, less physical with the tetchiness mellowed by youth and mild manner. He had two companions, two women and a young man.

Castrovalva was his first story - which concluded a trilogy of stories featuring the Master, in which the Doctor foiled an attempt to be trapped by the Master in a recursion trap. In Black Orchid, the Doctor showed his fondness for cricket and also met a "twin" of Nyssa in Anne Cranleigh. A touch of sadness occurred when Adric died saving Earth from the machinations of the Cybermen in Earthshock.

Omega returned in Arc of Infinity, bent on revenge from his defeat in The Three Doctors. The Doctor was sentenced to termination by the Time Lords (which fortunately never occurred). The Daleks, the Cybermen, the Master, the Sea Devils and the Black Guardian also returned who sent Turlough to destroy the Doctor in a trilogy of stories - the first was Mawdryn Undead and the last was Enlightenment. At the end of Enlightenment, Turlough became a companion. The fifth Doctor also met his previous selves during The Five Doctors, the 20th anniversary story.

The fifth Doctor's last story was The Caves of Androzani in which he regenerated after he and his new American companion Peri contracted spectrox toxaemia and he only had enough antidote to save her.

Peter still goes to conventions and has recorded some new audios for Big Finish
