In the next SSB, it'd be nice if they had several different versions of each Zelda character.
When you think about it, in regards to "Everyone is Here," no they aren't, because the TP versions of Zelda, Ganon, and Link aren't in, nor Ocarina Zelda.
(Ocarina Link from the original SSB & Melee is technically in as "Young Link.") And let's not forget TP Link could use the Gale Boomerang, and had the clawshot making him a li'l different from BotW Link.
Though, SSB fans might get annoyed having too many versions of the same character, plus that drama over "too many sworders." So maybe just have them as alternative costumes.
