That's the only name I've gotten for him. Doctor is usually a title, though I've never seen him do anything that seems particularly doctor-like...
I know he's nine hundred and seven. He looks human, but he acts weird and he'll say things that are kind of worrying, but he seems to be someone reliable and trust worthy if utterly mad.
And he has a time machine that looks like a police box that's bigger on the inside because it's another dimension.
