Well, @
Dalek_Kolt
in that case, I like Ghirahim, he's a cool character, but I hope he's not added, unless he's a dlc character.
Reducing Ganon to a Summoning character, I just don't see that happening, Zelda characters are different from Fire Emblem characters, meaning if somebody asks you who's the main 3 Zelda characters, the answer would be always be Link, Zelda and Ganon, all three of these characters make The Legend of Zelda, therefore with that said there is no way Ghirahim is replacing Ganon.
Keep in mind Chrom was going t be in, but according to Sakurai he was just another guy with a sword from the same series, at least Lucina has the whole hey she's a playable female character from the Fire Emblem series, but Chrom would have like Lucina been somewat a clone of Marth, except the worst part would of been no playable female Fire Emblem characters and I tell you what female characters is definitely a huge part of Fire Emblem.
Anyway my point is lets look at Ganon, he uses a Trident, this is a weapon nobody else uses, thanks to Yuga Ganon, we got a modern version of Ganon, also Sakurai once mentioned he was looking into bringing back classic characters, Little Mac was one, Isaac could be one representing the GBA era since Golden Sun was one of GBA's best, and then there is Ganon, think about it, Ghirahim is just another guy with sword too, except the real problem with Ghirahim is he does not represent the big evil of the Zelda series, only Ganon can do that, whether he's Ganondorf, Ganon, doesn't matter, he's Ganon, The King of Evil, if anybody should be the final smash, its Ghirahim turning the Demise Sword for Ganon to use.
Btw, how about Lorule Castle as a stage?
I still think the Spirit Train was a waste for the 3ds though, I'm not playing on that stage, Gerudo Valley will have to do, which is fine I guess, I put up with Termina Bay for 7 years in Melee.
