Samurai Goroh (F-Zero) King K. Rool (Donkey Kong) Wolf O'Donnell (Star Fox) Majora's Wrath (Zelda) Galacta Knight (Kirby) X (Mega Man X) [Replace Mega Man or buff him to make him more viable] Raichu (Maybe Alolan, replace Pikachu) Dark Samus (Metroid) Rundas (Metroid) Gandrayda (Metroid) Shadow The Hedgehog (As a Sonic alt) And, although I never used him, Snake should be back, as a respect to how good he was in Brawl. That is all I can list, based off the current and previous rosters. Feel free to list characters you would want, which I am not aware of. P.S. : Please, no one mention Goku, it is tired and old by now.
