3. Rassilon
As several Doctor Who serials have told us, there is another important figure in Time Lord History; Rassilon, the original ruler of the Time Lords who, according to differing sources, was either a wise and beloved leader or a ruthless tyrant. Although much has been made of the character in other media, Rassilon has only been a major presence in two

stories. In The Five Doctors, several incarnations of the Doctor journeyed to the Dark Tower on Gallifrey, Rassilons resting place, to stop President Borusas plan to steal the secret of immortality. His first full appearance in the show came in 2010s The End of Time when it was revealed he was the President during the Last Great Time War which wiped the Time Lords out of existence. Here, Rassilon is definitely a tyrant, determined to do anything he can to win the war. And, as you can see, hes played by one-time James Bond, Timothy Dalton!
