Your favorite Bad Guys?? Who are they??
They can be from movies, series, anime, manga, books, games, real life or even ST forum. Just donīt spam too much.
So lets start:
-Hal 9000 (2001 a Space Odyssey)
-Sherif Lucas Buck (American Gothic)
and of course
-Raito/Light (Death Note)
Edit: Forgot Catwoman from Batman Returns and Disney characters The (Phantom) Blot and Magica De Spell.
