Hello, I'm desperate finding the special character in marvel vs Capcom, if I'm right.. it's in the same era. (remembered Dan was also in the game)
It could have been a japanese version of the game (emulated).
It featured a geek/nerd/wimp with glasses, drewling and leeking out of his nose. He's wearing a Japanese schooluniform and looks kinda SD... big head small skinny body and a stupid nerdish haircut.
He uses his white schoolbag (kinda elastic) to attack in a girly fashioned way and looks scared being hit. Also uses two hands to push/attack off the opponent carefully while hes scared to watch facing back.
If he uses special (eveything flashing blue in the background) he throws alot of stuff like pencils, books etc. at the opponent.
He's so funny to play with.
