Ugh, I have been getting WRECKED by Ganondorf lately...I don't understand, no one else is giving me as much trouble as Ganon, what tips do you guys have?
Pro tip: Hit the enemy until he dies.
Even more pro tip: Kill the enemy before he kills you.
Seriously, this is not like I can say much with such tiny informations, though usually you will want to use Luma to control space a lot in this match-up, and don't get hit for any reason, Ganon deals at least 13% with any attack but the Jab, the throws(but the FThrow), and the individual hits of DSmash and Nair, considering he also that Rosalina's Launch Star has no hitboxes, in case Luma dies and he Sparta kicks you at the ledge at percentages as low as 40% you better read his edgeguard or you will die faster than you can say "Jolt Haymaker".
His Volcano kick is no more a joke thanks to the new mechanics.
Not only it is faster, as strong as his Melee self, with absurd range in both the vacuum and the explosion, and istantly breacks shields, but is also buffed by the 22 frame landing lag on air dodges and lack of invincibility frames when planking.
Also, his Warlock Punch can hit you out of ledge attack and floor attacks.
All of his smashes and the afermentioned Volcano Kick also K.O. at pretty early percentages, nearly always below 100%, it doesn't help that she is the fourth lightest character in the game, so watch out for them.
Most important, keep both eyes for his Bair.
It is a fast move for Ganon, but has a somewhat high hitbox, too bad Rosalina is so tall that he can hit her in a short hop, and it autocancels, and if it doesn't autocancel it has little ending lag other than having little start-up; it also deals 17% and has absurd knockback, surpassing his forward aerial, and apparently has the strongest knockback among the bairs, and, as it wasn't enough, Rosalina travels one of the shortest distances when trumped.
Tl;dr:Don't let him read you, he reads you, you won't even have the time of saiyng "Oh, it's just Gan..." before getting twostocked, you don't let him read you, and you will survive. That is essentially how Gannon works.
Forgot to mention: his Dash Attack has super armor and can tank the hit you space if you aren't careful, Wizard Foot ignores most weak, non-trascendent projectiles, so don't use star bits if you are in the wizkick's range, and don't take the habit of punishing everything he does in the endlag or he will bait an attack with an USmash and punish hard.
Needless to mention, since all of his attack have high damage, they might outpower non-trascendent attacks, it's not something to forget.
