10 Famous TV Characters Who Randomly Changed Personalities

2. The Master - Doctor Who

You can't expect everything you liked about a show to survive a 16-year hiatus. When Doctor Who was revived in 2005, it brought new Cybermen from a parallel world (sadly not from Mondas), a no-nonsense Doctor with a sensible haircut and a suitable jacket, and it focussed more on the companion and her family than ever before. If you complained, you were advised to thank your lucky stars Russell T Davies didn't reinvent the protagonist as half-human. The character of the Master though is one of the bizarrest personality crises of any huge television villain ever. Sure, we realise that he can regenerate, but into a stark-raving madman? Suddenly, the Master had always had a drumbeat in his head, something that was never alluded to before. The suave, calculated evil that Roger Delgado so brilliantly laid the foundations of was now replaced by John Simm, dancing to the Scissor Sisters and marrying an Earth girl; his return in 'The End of Time' only signalled a weirder direction, as the Master became bleach-blonde, incessantly hungry, capable of shooting lightning from his palms - why on Gallifrey can he now do that? - and intent on turning the whole human race into his clones, for apparently no other excuse than his own vanity. The Master has much more control over his regenerations than the Doctor ever has; why he'd choose to be more bonkers is beyond anyone, despite how entertaining Simm was in the role. The new look Master might not have impressed Steven Moffat enough to bring him back, but he's certainly influenced Andrew Scott's unhinged Jim Moriarty in Sherlock. One psychopath nemesis per franchise, Mr Moffat?
