Either Ezio Auditore de Firenze from Assassin's Creed II and Brotherhood, since he's a total psychopath, Batman, for the same reason, Kirby because he eats his enemies to gain their powers, and stars in the greatest platformers ever, Specter from Ape Escape franchise because he's a total psychopath, Tails from Sonic because he's kinda cute, or Giovanni from Pokemon because he's so cool.
