1. Ganondorf satys, but make him more than just a Captain Falcon clone.
2. Sonic and Pac-Man would be rad, but I don't want to see too many non-nintendo IP in SSB.
3. Wario and Captain Olimar are musts.
4. The whole Wario Ware gang should be in there SOMEWHERE. Perhaps as pokemon-type items
5. This doesn't have anything to do with characters, really, but I want the next SSB to be cell-shaded. Or at least have SOME toon shading in there, even if it's just for Young Link and Paper Mario.
6. Ninja Kong, from Jungle Beat should be included.
7. The only Advance Wars character that has any chance would be Sturm, which I think would be pretty cool.
8. Tom Nook for lol.
9. Reggie, duh.
10. I've never played Kid Icarus, but Pit sounds like a cool character.
11. Balloon Fight Guy could work, but giving him infinite flight is stupid because he could never fall off the edge.
12. I'd like Samus' dark and light suits to be more than just costumes, but I'm not sure if there would be enough differences to warrant an in-game Zelda/Shiek-esque morph.
13. Mr. Saturn needs to make a comeback. He's the best item in the game.
14. Captain N needs to be in it.
15. King Dededededededede would make a great addition.
16. Ridley would be pretty cool, I guess.
17. Meta Knight =o
18. Perhaps Diddy Kong, where you could switch to Dixie whenever you wanted.
