Just because megaman is more recognized doesn't mean he is better take Strider for example he is unique and brings a new fighting style same with viewtiful joe one of capcom's more originals games last gen there is Captain Commando another unique character.
Yes is MM Zero the one I was talking about again he is another unique character a sword wielder with long range weapons X is megaman's most recent design in the canon storyline of the series he fits better in the darker and more realistic atmosphere brawl has even the most recent canon game Megaman ZX is based on X not the original megaman.
Ok one, every company wil lchoose their mascot, if namco is chosen: Pac man is in, if sega is in: no brainer sonic is in, if hudson is chosen: bomberman is chosen, and if capcom is chosen, would they choose the mascot, or the ninja who has dissapeared for the last years in videogames or the guy in red whose games have been going down since the sequel of the original?
Gotta say Megaman
Yes strider would bring a new style of a character, yet he aint as popular, wanted or as recognizable as megaman is, and I doubt he apepared in sakurais list...
Joe is a great series, but isnt as famous as other capcom characters as megaman or any of the guys in SF...
Now EVERYTHING u said about zero is wrong, unique? hes just a cooler looking version of the already existing zero, a sword wielder with long range weapons? Umm LINK?! X is megamans most recent design? yeah like 10+ years ago, his most recent look is the ZX series, and believe me nobody wants them in brawl...
"he fits better in the darker and more realistic atmosphere" yeah kirby, pikachu, wario, zamus, delfino island, yoshis island stage, yeah they all fill the dark atmosphere bill, brawl aint about being realistic and having a dark atmosphere, its a game about fun, wacky, cartoon-like fighter, something the original megaman fits well, being a kid and all...
