i only just noticed this! Also Worf used to be a klingon lawyer, and ODO infiltrated starfleet security!
I'm not sure because his guide had other plans for humanity, especially when we find out that Al is a (cue dramatic music) ROBOT!
I have to admit, I found his performance a bit stiff. And why was that time traveler guy Janeway met once pretending to be the Federation's (idiot) President. And why was Odo wearing a mask when he tried the assassinate the Klingon leader? And why was . . . .
Who can forget the episode where Nick Locarno changed his name after the embarassing events of The First Duty?
You think that's bad? Trip Tucker was so pissed about the way he went out, he went and turned himself into a space vampire!
I was watching 2012 the other night and I thought the American Ark captain looked familiar. Turns out he was Hollis Mason in Watchmen and..... Vreenak. IT'S A NITE OWL!!!
That was after he faked his own death in "These Are The Voyages," but I'm surprise the entire cast didn't do the same.
Not to mention Gul Dukat managed to travel back in time to the 1800s, and disguise himself as a human and play poker with Data. And he has an identical twin called Macet.
