Are there any video game characters that, if they existed in real life, you wouldn't even think of flipping them the bird? I can name several, and yes, these can be heroes, villians, and even neutral entities:
Any and all characters in the Marvel universe (especially Juggernaut)
Shadow (Final Fantasy VI)
Vincent and Sephiroth (FFVII)
Amarant (FFIX)
Auron (FFX)
Sol Badguy (Guilty Gear)
Strider Hiryu (Strider)
Firebrand (Ghosts N' Goblins/Gargoyle's Quest)
Jo Musashi (Shinobi)
Ryu Hayabusa (Ninja Gaiden)
Hell, any ninja (All video games [every game needs at least one ninja!]) :P
Allen O' Neil (The lovable Metal Slug Super Soldier!)
Kagekiyo (The dead samurai protagonist of Genpei Toumaden)
Kirby (that little puffball could eat me, for Gouda's sake. Or worse... he could eat my NES... then assimilate its abilities and kick my ass with them!)
Any game characters you fear? Or at least have nightmares about?
