You just KNOW its Dan the guy falling into the water, the "beat up" car from SFII is also there, I cant recall the names of some of this guys tough, for instance, that "hooded" guy near the Ken's
The guys with half their faces covered in metal (like the cloaked dude) are the Shadowloo observer androids from the first animated movie. They were pretty popular at the time but never appeared in an offical fighting game, I don't think.
Tagging all the characters left from Final Fight I. Made the appropiate corrections... BTW... I just had an idea for a new Capcom 1 on 1 fighting game. It could be called FINAL FIGHTER and include characters from the first game only, LOL...
