There are many unused fighters
One source states, "Unused characters are a reality in fighting games and Smash Bros. is no different. Since the beginning, characters have been cut due to time restraints, legal issues or hardware limitations. Here's a look at the some of the most notable. The original Smash Bros. considered Marth, King Dedede, Bowser, and Mewtwo. Rumors of Meowth are unfounded, but his inclusion would have been amazing. In Melee, retro characters from Balloon Fight, Urban Champion, Clu Clu Land and Excitebike were ousted for the Ice Climbers. Banjo Kazooie was also discussed, but could not be accessed due to legal constraints. In Brawl, characters such as Dixie Kong, Plusle and Minun and Toon Zelda can be found in the files. Krystal from Star Fox Adventures and Geno from Super Mario RPGwere also considered, but were let go. Finally, Smash 4 considered Heihachi, Takamaru and Chrom as fighters before ultimately dismissing them"(Reid).
