Revan - Knights of the Old Republic - not sure if he counts as he just became me, essentially, but me with force lightning and a power unironically named 'Kill.'
Ghost - Modern Warfare 2 - actually liked the bugger. Plus the skull face is awesome, and he got there before Halo Reach's Emille.
Garrus Vakarian - Mass Effect 2
Anthony/Ben Carmine - Gears of War (2) - more or less the same person.
Sten - Dragon Age - the only character who I didn't have to work to get to like me, as it turned out we agreed on almost everything. Not sure what that says about me, though...
