I think Sparkster (Rocket Knight) would be a really good canidate for the brawl, I mean, sure he's not really popular or that much known, but he has alot of smash qualities, I mean, he wouldn't look strange in the game, he'd look like he belongs in my opinion, plus, he has different color schemes and he has various attacks (btw, Sparkster is a Konami character). As for Capicom, I bet you most people might pick Mega Man or Ryu, lol. I dunno why but to me neither Mega Man nor Ryu don't look to me like they belong, yet Mega Man is the most requested Capicom character as far as my research reads.
