Case for: He has appeared in several different time periods, wearing several different faces – from a beautiful child to an old man. He is – timey-wimey alert – the Once and Future King. He created Stonehenge as a burial place – where the Doctor himself would one day be incarcerated in the Pandorica. And he’s half-human – just as the Doctor has claimed to be (but we’re not saying that’s true, so don’t write in).
The Seventh Doctor himself was identified as Merlin by Arthurian knights from a parallel universe. The warrior Ancelyn claimed Merlin had “many faces” and rode “the ship of time” which “deceived the senses by being larger within than without”. Can’t think what he’s referring to.
Case against: None. He’s a Time Lord, plain and simple. In fact, he’s probably the Doctor.
Time Lord rating: 10/10
Case for: An alien trying to blend in on Earth, Ford Prefect rescues Arthur Dent shortly before the Earth is demolished to make way for a hyperspace bypass. He then travels through time and space with his new human companion, accompanied by a towel and a copy of The Hitchhiker’s Guide to the Galaxy. He has adopted the name of a British saloon car because, he claims, his real name is unpronounceable on Earth. Enigmatic and at least 200 years old, he wanders the universe saying things like “Time is an illusion, lunchtime doubly so”.
Case against: Claims to be a native of Betelgeuse. But then he’d previously claimed to be from Guildford, so who knows what to believe?
Time Lord rating: 8/10
