Then there are the serious mother-flippers who go too far and skirt the line of good and evil, genius and madman. These are the bad-ass Time Lords, time travelling insaniacs who the Doctor regularly finds himself trying to stop.
But which one of them is the most bad-ass? Which of them would command a battalion of cruisers and conquer the universe, or perform heinous experiments on all other living creatures as “research”?
We’ve rounded up 10 of the worst Gallifreyans ever…
Morbius - his attempt to turn the Time Lords into a force for evil lead to him being executed.
Rassilon - the founder of the Time Lords, he lay in rest for millenia until the Time War and his resurrection to lead his people against the Daleks.
Omega - time travel would not have been possible without this stellar engineering genius who was left behind in the collapsed black hole that gave the Time Lords their power. Forgotten, he exacted revenge from an anti-matter universe.
Chancellor Goth – an ally of the Master, he fought the Doctor in the Amplified Panatropic Computer Network or APC Net, specifically the part known as The Matrix.
The Master – possibly the Doctor’s greatest foe, the Master is insane, genius, manic, destructive and charming in equal measure.
The Rani - a Time Lady whose immoral experiments have lead her to cross the Doctor’s path on several occasions.
The Valeyard – essentially the Doctor, the Valeyard is an amalgam of the dark side of our favourite Time Lord, brought into being by a corrupt Council of Time Lords.
Castellan Kelner – a toady, obsequious security chief who sold the Time Lords out to first the Vardans and then the Sontarans.
The War Chief – the Time Lord behind the terrible events of The War Games, he was responsible for capturing humans from many eras and pitting them in battle.
The Doctor – could the most bad-ass Time Lord of them all actually be the Doctor himself? In The Waters of Mars he declared himself the Time Lord Victorious and attempted to bend the laws of time to his will; in Remembrance of the Daleks the Doctor destroyed Skaro’s entire solar system; in The Runaway Bride he destroyed the last of the Racnoss. Oh and he destroyed all of his own people and all of the Daleks in the known universe by ending the Time War.
So which is it to be, dear reader? You decide…
