Warlock Punch (魔人拳 Majinken Demon Man Fist) is Ganondorf's neutral special move. Ganondorf winds his fist back, charging a punch, for approximately 72 frames while a purple aura surrounds his fist. He then suddenly throws a devastating punch.
This move is very powerful as a single move causes 30%-34% damage and has very high knockback. It is an attack that can KO at low percentages and can even KO light characters under 10%. Except on utterly defenseless or paralyzed opponents, this attack is very hard to use in combat because it is very slow and predictable. Because of this, the move is practically useless in competitive play. In the air, Warlock Punch is even more powerful and does about 37%-40%, with higher knockback. But the very slow start-up of the Warlock Punch combined with Ganondorf's poor jumping and fast falling speed makes landing the Warlock Punch while airborne extremely difficult.
This move is considered a "clone" move of Captain Falcon's Falcon Punch as it has the same animation, nicknamed as "Ganon Punch" by fans, but as mentioned above, it is slower, deals more damage, and has higher knockback. Also unlike the Falcon Punch, it is extremely difficult to attempt a Sacred Combo facsimile with due to its lag. Later in Brawl, Ganondorf has a different animation with the attack, where he instead does a powerful forward backfist with his left hand instead after a waving motion.
 Reverse Warlock Punch
The Reverse Warlock Punch is an ability introduced in Brawl. A player can pull off a 180° punch by turning in the opposite direction during the charging period. This deals roughly 3% more damage than a normal punch with more knockback. This move can be done on the ground and in mid-air, but on the downside, it is about 0.5 seconds longer than a normal Warlock Punch. This reverse Warlock is good for mindgames (as with Falcon's) and does serve as a way to turn a match around, but is still very laggy.
Also, the animation for the punch has been changed. Instead of pulling his arm back like a slower Falcon Punch, Ganondorf waves his arms, pulls back both arms while gathering energy, and punches backhanded with his left hand instead of right.
Warlock Punch usually guarantees a KO at around 20-29% damage should it be landed (with a reverse aerial Warlock Punch being able to KO at 12%), the second lowest of any special move without special criteria (such as Oil Panic and Judge), behind Ike's stage 8 Eruption, which can KO at 5%.
Warlock Punch has four stages of damages and knockback depending on what type of punch is performed.
Ganondorf never uses the Warlock Punch as it is in any Zelda game, but similar attacks, fitting in with Ganondorf's motifs as the Warlock Punch does, have been used in several games. In Ocarina of Time, Ganondorf uses dark magic and a similar shout as in Melee to block Navi from approaching him in order to disable Link's ability to Z-Target. Additionally, in Wind Waker, he fights using his fists during certain cutscenes, showing massive physical strength and prowess in hand-to-hand combat. He knocks Zelda out during the final battle with a backhand slap, akin to the Brawl version of the attack. However, none of these are actually the Warlock Punch, despite their similarities, and the move is overall, non-canonical.
