Peter Davison

The Fifth Doctor is the first Doctor to feel every bit his age, which is of course contrasted by his physical appearance (Peter Davison was 29 when he took on the role, making him the youngest actor to play the Doctor until Matt Smith, who was 26 when he was cast). He’s thoughtful and still, far less wordy than his predecessor, and perhaps partially due to the youth of his Companions, the Fifth Doctor is the most paternal since the First Doctor. He can be stern, one of the earliest to show the Fury of a Time Lord so common to the modern series, but he also has a sense of fun, taking time off here and there to catch a game of cricket and relax. He’s also the most approachable of the Classic Doctors, with a breezy demeanor that contrasts the Fourth Doctor’s manic energy.
