Marvel vs Capcom 2 - any mix of Akuma, Captain Commando, Shuma Gorath, Wolverine (bone claws), Cammy, Venom, and Cable.
Super Smash Brothers 64 - I've yet to meet anyone who can beat me at this game in a best of 3. Sure I'll lose 1 game once in a blue moon, but no one can do it twice. I've got a 3.x second record for my fastest kill using Yoshi. I excell with Kirby, Pikachu, and Yoshi. No one ever expects a good Yoshi. Team my Yoshi up with a good Link and you're in hell. Bombs, eggs, and 'rangs errywhere. I fuck around with Link when I feel like being an annoying asshole.
Super Smash Brothers Melee - Ganondorf for life. With the exception of Mow and a few select others, I don't think anyone at Smogon could handle my Ganon. Granted, I still have to master l-canceling, but ffs, you don't take the hardest hitting character lightly.
FUCK I LOVE SSB 64/MELEE
