Q in 99 was Q in a videogame, a character that pretty much matches what you would expect the personification of Q to be
A man in a fedora and a tench coat, wearing an iron mask, only able to communicate through grunts and the subtle expression of his movements
The game he appears in usually provides information on all of tbe featured characters, but all of Q's information is completely unknown
The only story we have to go off of is that he's being hunted by the CIA, and he also does battle with the main antagonists of the game, which are The Illuminati
