Brawl Roster(PM roster, seperate the pokemans from the pokeman trainer), bring Mewtwo back, and roy, in other words, all characters from SSB64,SSBM and SSBB, except for pichu and maybe the Doc.
Now for new comers, it would be nice to have like rivals or whatever, I love me some rivals like in Battle Royale, that said...
Star Fox:
Krystal , Leon and Panther person: Krystal Rival with Panther, Leon with Falco, Fox with Wolf
Mario Bros.:
Waluigi (with a nice moveset, no tennis racket)Rivals with weegi, and bowser, like mario rivals with wario and bowser, unless they add king boo to rival luigi.
Bowser Jr. (Toon Link is too Link as Bowser Jr. is to Bowser, in other words a faster but weaker clone, sorta, kinda) rivals with peach I guess..
Metroid:
Ridley...nah, unless they normal size him, Instead of Ridley , why not a Bounty Hunter from the DS game.
F-Zero:
Not a fan of Samurai Goroh, I'll like to see a badass looking character, maybe the guy that drives the Shadow Bull.
Zelda:
Vaati would be nice, like a TP-fied version of him.
Fire Emblem:
a Female character that's not Lyn. Maybe a mage/wizard/priestes or wahtever character.
Kirby:
the drawing girl
DK:
I don't want to say KKR, not a fan of the series anyway.
Pokémon:
Keldeo, since they made o movie of him, and he speaks, like mewtwo and lucario.
A pokemon rival set would be too much I guess (bulbasaur, charmeleon, blastoise) and they should be there own character, like they did with the pokemans in Project M.
Nintendo should just make a "Pokemon Smash Bros." I would like to see that haha but just my opinion.
Kid Icarus:
apparantly there is a Dark Pit,if they add him, since it can just a color change like Link with dark link, hope it's like a Fox - Falco relationship thing as in moves, or just a completly different set.
3rd Party:
I think the're more chances of having Zero but from the Megaman Zero franchize, I wouldn't mind
not sure if this is third party, but the guy from Tales of Symphonia or whatever.
So much for the rival thing
haha
