Ezio Auditore da Firenze because he knows what the ladies like, and has a deadly ancient artifact that can make his enemies attack each other, or make them stab themselves.
The Arbiter from Halo 3. He is so bad*** and he always helps the Chief like the time he flew forward Unto Dawn through the portal just in time before they were all stuck in Halo.
its safe to say that the best character of all time, bar none, is SUPER MEAT BOY!!!!!!!!!!!! You'll beat that Mr. Fetus S.M.B.! and then you'll be reuinted with bandage girl!
Fox McCloud. I mean, he's a vulpine mercenary space pilot with the best piloting skills in the galaxy, and he flies possibly the coolest fightercraft ever created - the Arwing! And it turns out he's not bad at ground combat or martial arts either. Plus, he's got great teammates and a lovely woman to back him up. You don't get any more awesome than Fox McCloud.
