The "Coolest Moves" post inspired this, and one of my comments in that thread got me to thinking about all of them again, so here's this thread.
The purpose of this thread isn't to see just who your personal favorite character is, it's any character from any fighting game you've ever played that you played so well, you had guys lining up at the second controller of the machine waiting to beat you so THEY can finally play more than two rounds, or at home when you'd have a revolving lineup of your friends on the second control pad, waiting and hoping they'd beat your ass at the latest Street Fighter incarnation
So, with that in mind, I'll get it started with three particular games.
Marvel VS Capcom: I OWNED with Gambit and Morrigan. Same with MvsC2, only I also had Megaman on the team.
Capcom VS SNK: Ryu, Mai Shiranui, and Terry Bogard. UNBEATABLE. Heh heh heh
going back a little bit: Street Fighter Alpha 3: Akuma. UNSTOPPABLE. BWA HA HA
