If you keep getting Flame Choked on last stock and Wizard Footed when trying to combo constantly, as well as seeing multiple U-Tilts and Warlock Punches, that's me.
Ganondorf is a very, very intimidating and actually viable character. If he can land a grab on you (it's not that hard actually), he can D-Throw > F-Air, U-Throw > U-Air, etc. His throws have so much potential, and he has the most powerful throw in terms of damage, which is his F-Throw (13% damage and can lead up to combos). Sure, you may bring up the argument he has the worst grab in the game, but he doesn't, his grab game may be bad, but certainly not the worse (I miss more grabs with Falcon than I do Ganon). His grab game can extend further to his Flame Choke, specifically his non-techable aerial FC, which can lead up to some nasty roll chases. The most likely thing is that the opponent will indeed try to attack, so a good, quick SH D-Air should do the trick due to its slow, but reliable speed.
And his Wizard's Foot > Wizard's Foot ground combo, which leads off the edge, is amazing at moderate percents, and it's an entirely viable gimping move due to this fact: the first attack sends the opponent off stage, and if you time it right, the second attack should eat their second jump up and send them even further back. Now, this method definitely doesn't work with Fox, Falco, Kirby Cast, Jigglypuff or certain others, but to characters like Pit, Dark Pit and Rosalina, if Ganon gets back on the stage, he will edge-guard like no tomorrow on you until you're KO'd, and will NOT let you get back on the stage. Sometimes, on characters like Duck Hunt, he can trick the opponent by using U-Air and then recovering, just to ensure an insulting edge-guard. Oh, and don't get me started on the Sourspot of Ganondorf's D-Air; that thing's more of a sweetspot.
No one really knows the usefulness of the U-Tilt, other than being a very powerful vertical-horizontal KO tool and an instant shield breaker. However, it's perfect for certain characters trying to get back on the stage, especially those not careful enough to even recover correctly, and its range is beyond menacing, as it covers a lot of range horizontally and vertically. This is also a good tool for mind games, especially at the edge, again, since if an opponent is trying to recover, and gets up on the stage, Ganondorf can simply turn around and activate the U-Tilt.
His combos are plentiful, and a tad underrated. Like above, he has D-Throw > F-Air, and U-Throw > U-Air, but he has, like explained by everyone, Dash Combos. All of his aerials can be used with Dash Attack, especially the mainly used U-Air. There are many other ones, like D-Tilt > F-Tilt and such, but people have to experiment and implement. Ever tried Dash Attack > U-Air > F-Air? Quite useful for racking up the damage quickly.
Customs...where do I even begin; his 2nd N-Spec, Warlock Blade, is a great pressure tool, as well as a fast and efficient attack, with a chance of breaking the shields off opponents. This is especially deadly to Jigglypuff, obviously, but there is so much potential, such as the bettered use of the combo, N-Spec > U-Tilt, if the shield is broken, because the U-Tilt becomes the new Warlock Punch. Then there's his Wizard's Dropkick, which gives his shoddy recovery a better chance, as its horizontal distance goes well with his vertical recovery U-Spec. If Dark Fists is involved, he has a better and more powerful recovery and attack. I'd prefer that moveset over any other, unless I want early kills by the D-Spec 1.
I might try making an MU chart for Ganondorf myself, and I enjoy using him in the game; he's a very viable character to me, and you guys do not know what you are missing with him. He's a really great and steel-solid character. Sure, he lacks in range, but it's dangerous to go against him in Footsies, especially when he lands the hit. His range is compensated by certain customs, though. An annoying and a viable character, something I enjoy playing; not deserving of low tier.
