Nintendo
Mario (with an alternate Luigi costume, complete with unique voices! Wow!)
Link
Pikachu or Pokemon Trainer (like the one in Brawl)
Kirby
Sega
Sonic (with an alternate Shadow costume complete with etc who cares)
AiAi (I don't really know honestly)
Gilius Thunderhead
General Winter

Generic shooting man #3
Generic shooting man #4
Capcom
Zero (you know as well as I do that they don't care about Megaman)
Ryu
Dante
Morrigan
Namco
Pac-Man
Klonoa
Heihachi
Lloyd Irving (he's really the only Tales characters I've heard of and I know nothing about the series)
Other companies I didn't feel like sorting through
Someone from Elder Scrolls
Isaac Clarke
Big Daddy
Rayman
Solid Snake
Raiden
I can't think of anything else at the moment.
Maybe it would be like SSB where the more popular a franchise is, the more characters from said franchise would be added. In this case, just replace franchise with company. That's actually how I'm going to justify being lazy.
