Arle Nadja. Probably won't happen, but I can dream, right?

James Bond. His skins could be the different eras. (Connery,Bronsnan,Moore,Craig,etc)

[Arazeml]

Personally? If Lucas can come back, I wanna see Wolf and Roy (Fire Emblem not Koopaling) darnsit!
I know ROY IS MARTH CLONE but honestly, Roy is less of a Marth Clone than Lucina is...
I'm not a big fan of Snake (I don't MGS), but I wouldn't mind seeing him return. As for Newcomerrsss, Dixie Kong, maybe Krystal, King K. Rool, Klonoa (obviously), Banjo and Kazooie, and Rayman.
The 3DS datamining has me curious though, SF Ryu WOULD be interesting, but I dunno.

[SuperKlonoa64]

Well Klonoa obviously, but I also want to see Shantae and Bravoman make it in.

Umihara Kawase! Because her games were awesome back on the Super Famicom/SNES

[Spirit Macardi]

Aside from Klonoa, I'd be all for seeing Bayonetta. They'd no doubt need to tone down the clothing loss when she uses her magic, but even then she's got all manner of possible attacks and weapons. And for the Final Smash, she could summon Gomorrah, Madame Butterfly, or one of her numerous other demons to attack.

[the_darai]

Umihara Kawase! And of course Klona.

Umihara Kawase! And of course Klo.
