That box is fanart, but if it isn't then we'll be able to use Magnus, Megaman, Knuckles, Rosalina, Cloud/KH character, Bowser Jr. would all be playable with the chance of Baby Mario and Oshowatt getting in as a Menu/Assits, or their own characters.
As unlikely as he is, I'd love Oshawott in Smash Bros!
So fake. Look at the newcomers supposedly on the best. Megaman, Ghirahim, Knuckles, Rosalina, etc., in any case, none of them are likely at all except maybe Megaman. And how is Smash only number 4? It should be number -34983748937985235962875.
Palutena, Isaac, Ridley, King K. Rool, and Anna for SSB4 "I'm willing to bet money that Waluigi, Chrom and K. Rool are in this game" -DynasticAnthony
