Let's categorize them into the GAR (men) and MO-E (babes). Saka ko na post yung MO-E part.
Iori Yagami (King Of Fighters) - None can compare to his charm and fierceness. I'd pick him over Kyo Kusanagi any time of the day.
Terry Bogard (King Of Fighters, Fatal Fury) - The "Lone Wolf" flag carrier of SNK.
Gai Tendo (Buriki One, King Of Fighters XI) - At first I thought he was Baki The Grappler, but he's even better.
Bryan Fury (Tekken) - Cyborg. Cop. Zombie. Call him whatever. He'll beat you up any time of the day.
The Belmont clan (Castlevania series) - Whipping supernatural arse since the Medieval ages. Fo' real!
Kratos (God Of War) - Need I explain why? He's the effin' God of War!
Cloud Strife (Final Fantasy VII) - Big-arse sword equals major pwnage.
Squall Leonheart (Final Fanstasy VIII) - Don't let the "cute boy" image fool you. He's one mean sonofagun.
