2. The Doctor's An Alien
The Doctors a Time Lord from the planet Gallifrey. It's a cornerstone of the series but, although the specifics of this were not revealed until the Second Doctors final story The War Games in 1969, he was assuredly an alien from the start. Right? Actually, he may never have been... In the Eighth Doctors only television appearance in a TV movie entitled, um, Doctor Who the Doctor reveals that he is in fact half-human, on his mothers side. We could perhaps right this off as a newly-regenerated Doctor spouting nonsense but shortly after the Master, oh yes hes in this too, discovers the Doctor possesses the retinal structure of the human eye the Doctors half-human he reiterates, no wonder. So, there you have it. Everyones favourite eccentric alien is not, in fact, completely alien. Many fans have been waiting (or perhaps hoping, in many cases) for a line in an episode broadcast since to contradict this but no such line has come. Until then we must assume that the Eighth Doctor and the Master were telling the truth. What could top this shocking revelation? Is there anything about the Doctor we know for sure? Doctor Who, indeed! Well, now you mention it
