If Ganondorf really is to be a clone of Captain Falcon, then I'd rather see him replaced with Monster Ganon with a Ganondorf costume, kind of like how in Tekken Tag, Dragonov had a Ganondorf costume.
This could count as a new character and he'd have moves Monster Ganon would wield the Trident, he'd have moves like that freaken energy ball we always wanted on Ganondorf replacing Ganon punch, Earthquake, his recovery could be him thowing his trident then warping to it, and of course the Trident stab, I'm also in support of Monster Ganon replacing Ganondorf, bt only Monster Ganon because we need Ganon in this game whether he's Ganondorf or Ganon and I can't accept the likes of characters like Ghirahim replacing him no matter what move set they have.
However I think we do actually have Ganondorf in, and yeah even I mained Ganondorf in Brawl, but after recent study I discovered I was better with Zelda which my second main, and that Bowser is actually my best character, Ganondorf isn't my best, but I like using him regardless because this is one game he's playable in and out of Zelda characters, I freaken hate Link, I like a lot of Zelda characters, but Link ironically is my least favorite, I need my Anti-Link in this game.
I have reason to believe Ganondorf was supposed to always to have his sword, but for some stupid reason they decided to just throw Captain Falcon's moveset on him, whether the sword moveset is somehow failing, I don't know, but what supports this theory is the presence on Ganondorf having a sword in Super Smash Bros games.
