Ganondorf is probably armed with the most powerful moves in the game. Almost all of his moves have the ability to kill.
Ganondorf's Jab, Down-Tilt, and Forward-Tilt are suprsingly fast and are usually used as followups to Side-B and kill moves on stage. F-Smash can kill insanely early if you managed to get hit by it (especially Up-Angled,) and Up-Smash has Inturrupted as Soon As frames. It reaches through the platforms on Battlefield so keep that in mind. Down-Smash hits on both sides, but it has terrible startup lag, end lag, and is unsafe on the shield. Ganon's down smash is never used
Up-Tilt is one of the most damaging tilts in the game that can kill insanely early if it connects. It has wind properties that pull you into the attack, ***** shields, and can be a useful edgeguarding tool.
In the air, Ganondorf is known to do his thunderstomp to approach. It deals massive damage, and can lead to followups for more damage. It isn't uncommon to only be hit 4 times and be up to or over 70 damage. N-Air's first hit does more damage and has more knockback, while the second hit has sex-kick properties. F-Air is a powerful move that is still a good finisher. It comes out quick with a somewhat deceptive hitbox. It's massive landing lag makes it a situational move. B-Air and Up-Air are quick and have good range and power.
Ganondorf's specials are quite situational. Warlock Punch is extremely powerful, especially when reversed, but is difficult to land. His Side-B is one of his favored moves, but it's kind of limited in this matchup with two Climbers present. He can't techchase without being hit, but he gains Superarmor when he grabs a Climber with this move. Up-B has almost non-existant hitstun and little knockback when it catches a Climber. If he manages to catch a Climber with the other one not present, you can most likely N-Air him upon release. Ganondorf mains are aware of this and won't use Up-B as an offensive attack. The other Climber will hit him out of his attack most of the time. When recovering, he can uppercut you if you are close to the edge, so lookout for that.
Ganondorf's Wizard Foot (Down-B) has many uses. On the ground it can push you off the stage. He can also use it to cancel at the edge with little lag. In the air, it can spike with great power, or kill you off the top at around 100. It also has a landing hitbox.
Ganondorf is pretty good at edgeguarding. All his aerials knock you out of Squall Hammer. Down-B when used in the air can eaisly kill as well. Up-B is probably a better recovery option.
Ganondorf can **** Nana with his powerful moves if the Climbers are seperated.
Ganondorf does ok against SoPo. SoPo can chaingrab him for a while and can knock him off stage. He can knock us out pretty far with any move. His approach is still kind of limited though.
Ganondorf is the slowest character in terms of mobility on average. He also has no projectile. Blizzard stops his approaches and beats everything he has. Desynched Ice Blocks can force an approach while alternating Blizzards give him trouble up close. Squall Hammer racks up the damage. Popping him in the air for juggling works very well at low percents. He doesn't have a great recovery, so killing him at the sides works well. Spiking him also works pretty well. Getting the grab shouldn't be too difficult and chaingrabing him shouldn't be too bad either. Rising B-Air out-spaces him and should be able to hit him.
Delfino is most likely their best stage. With the water for easy spiking, and the Side-B to drag you into the water, easier Gannoncides (though he can eaisly grab the wrong Climber ) and platforms that make it easier to attack though, it is not a stage to take him lightly. Norfair is another stage to consider banning. Stages that have uneven terrain like Lylat makes it more difficult for him to perform his attacks smoothly. Flat stages like Final Destination make it extremely easy to limit him.
I think it's 95-5 in our favor. Ganondorf has power, but will struggle to get attacks in.
