it says n00b, but I've been playing SSBM long before I found this place.
Diddy kong: Don't know much about this guy, but it sounds like he would be awsome, thats all I need
Krystal: The staff makes her a very plausible addition, not to mention a combat style lacked in SSBM
Dedede: SSBB is made by the kirby man himself, so quite plausible. I don't have much of an opinion myself however
Ridley: He just may work, I'd like to see how this guy would fit in SSBB
Sonic: Oh the possibilities. I'm not much of a sonic fan, but he could fit right into SSBB. almost guaranteed
Baloon fighter: haven't given it much thought, I suppose he could manage. I don't have much to say about this
Geno: If I knew more, I'd say more. but he seems to be a worthy candidate.
Megaman: why not?
Wolf: Many believe his moves would be similar to fox. Big whoop-dee-doo, many SSBM players prefer Falco over Fox despite their similarity in moves. whats wrong with just a slight variation between only 2 characters? Personally, I'd like to see this guy make it in, however improbable.
Lucas: I wouldn't mind a few psychic characters, plus hes better looking than Ness
Olimar: this could be... something... pikmin... I'm not quite sure what to think about this one
Stafy: I don't know much about him, therefore, no opinion
Fawful: he could be real funny, gotta love that mustard.
Tom Nook: if the likes of Game & Watch can make it in SSBM, why not Nook in SSBB? I wouldn't mind clobbering an opponent with a shovel every now and then.
Hector: whatever,
Skull kid: I know I'd play him if he were included. not so likely though
Kamek: Don't know much about him, he seems like a worthwhile pick from what you've said
Hitmonlee: I don't see much potential for this pick, than again, it is the "no chance in hell" category
Paras: at first, I wouldn't have thought so, but you put up a very convincing argument. I say go for it.
Koopa Troopa: the only thing this guy is really good for is stripping him of his shell, and chucking it at someone.
Prince: umm... well... I don't really know
the firepit: no arguments here.
