Fourth Doctor

If the Second Doctor was your grandad's favourite incarnation, then chances are the Fourth Doctor is your dad's favourite incarnation. Actor Tom Baker made the role his own, drawing from previous performances but also adding his own bohemian shine to the character. Like the Second Doctor, the Fourth Doctor often played the clown to disarm his opponents before turning the tables on them with his razor-sharp wit. Speaking of wit, this Doctor always has a quip up his sleeve, making him one of the most entertaining incarnations to watch.

It helped a lot that the Fourth Doctor's era began with the tenure of the legendary Philip Hinchcliffe, who gave the show a gothic vibe for much of the Fourth Doctor's early tenure that led to some truly timeless stories that still hold up to this day, unlike the more garish era of John Nathan-Turner, whose early tenure as showrunner defined the late Fourth Doctor era. To this day the Fourth Doctor is the longest-running incarnation, as Tom Baker stayed in the role for a whopping seven seasons.
