That's if you're playing Ganondorf like Captain Falcon which you're not supposed to. It's like if I tried being speedster, Flash-like with Falco. That ain't Falco and that sure as hell ain't Fox.
Ganondorf's more or less a punisher and a one-hit-killer. The only issue with that is he's pretty much a defensive character with not a lot of offensive options. Can he run after you? Yes, but not as well as Captain Falcon, Fox, or Sonic. Can he play an air game? Sort of, but not as well as Jigglypuff, Meta Knight?, and Kirby? Can he do off-stage well? Unless off stage meant being near the ledge and doing an attack when someone gets near, then no. He can't do what Falco, Jigglypuff, Kirby, Meta Knight, Rosalina?, and the Villager can. Don't even think about zoning with Ganondorf. The thing Ganondorf does better than anyone else, well, as of now since who knows, Mewtwo could come back packing 300lbs of muscles and attacks that rip through the air, is punish. One hit from him is much worse than one hit from Ike, Triple D, Bowser, and DK.
