All-Star Battle ★ Wamuu
Wamuu was one of the first four characters announced for All-Star Battle, the others being Jotaro, Joseph (Part 2) and Gyro Zeppeli. Along with Esidisi and Kars, Wamuu uses the Mode Style as part of his moveset, which allows him to temporarily boost his strength and performance among other things, at the cost of the Heart Heat Gauge.
Vampire characters (Dio Brando, DIO and Vanilla Ice) and Pillar Men characters (Wamuu, Esidisi and Kars) can't fight on stages that contain sunlight. To play on those stages they need to be equipped with the Red Stone of Aja on the character select screen, which is unlocked by beating their respective parts in Story Mode.
Command List
Wamuu has 950 HP.
During a fight, Wamuu can use several different attacks that were featured in Battle Tendency. Wamuu himself is the tallest character among the entire roster of 41 characters (save for Vanilla Ice with Cream active).
ON GROUND Wamuu can activate Wind Mode in order to not only increase the overall damage of his moves, but exclusive to him, grant him super armor while performing them. The Heart Heat Gauge slowly depletes while this mode is active, and as such, this mode will last until the HHG empties or can be freely canceled with another press of the Style button.
+ ON GROUND Expending a stock of the HHG grants Wamuu access to Wind Protector, turning him invisible. This mode is on a set timer and will end when the stock consumed to activate it is used up. Wamuu's abilities are strengthened even further, he is granted passive super armor at all times, and he is automatically immune to most projectiles aside from those fired through HHA/GHA, as well as Caesar's Bubble Cutters specifically.
Wind Protector also possesses the special effect of allowing Wamuu to execute his HHA at any amount of Heart Heat while active, even when at less than one stock. However, doing so will immediately end the Mode and completely empty the Heart Heat Gauge.
+ 2 ATK Buttons ON GROUND This skill costs half a stock of the Heart Heat Gauge. Wamuu blinds himself and reveals his horn for the rest of the match. He loses access to Chain Beat (the ability to chain normals together) and by extension Easy Beat, but he is given access to the ability "Whooosh!", and deals increased chip damage (damage dealt to an opponent through their guard) in all of his attacks and abilities.
+ 
ON GROUND Wamuu steps forward and delivers a heavy lariat that knocks the opponent down if it connects, making them hit the floor hard enough to bounce. (Comboable)
+ (rapidly tap S to extend duration) ON GROUND Wamuu leans forward and spins the wires on his headgear into a vortex to hit and push away the opponent. This move has the added effect of nullifying incoming projectiles with the exception of those fired through HHA/GHA.
+ 
/
/ ON GROUND Wamuu performs an near-instantaneous upward reverse kick augmented by the wind that knocks the opponent into the air. This move functions as an anti-air and reversal. (Comboable)
+ // ON GROUND IN AIR OK Wamuu somersaults in-place and unleashes a downward punch that knocks the opponent down. This move is a middle attack that cannot be blocked crouching, and can also be used while in the air.
If Wind Mode or Wind Protector is active, the attack will instead cause the opponent to slowly crumple instead, leaving them open to further attack (Comboable)
+ // + // ON GROUND Wamuu performs a slow forward flip, and while this does do nothing by itself except act as a feint or cancel, a second press of the attack button during this initial animation makes him launch into a flying kick forward. If it connects, a second kick sends his opponent flying a long way.
x2 + ON GROUND WHEN DOWNED This move can only be performed if the opponent is down; Wamuu brings out a broken column and smashes them with it. Should the opponent recover in time, this skill is still a middle attack that cannot be blocked crouching.
+ // ON GROUND This move is only available after "I shall see the wind!" is performed. Wamuu slides forward horn-first to attack the opponent, covering a moderate range in front of him. (Comboable)
ON GROUND Wamuu jams his fingers into the opponent's neck before slamming them into the ground.
+ 2 ATK Buttons ON GROUND Wamuu uses his signature Divine Sandstorm. Rapidly spinning his arms, he generates a huge, devastating sandstorm vortex on screen, covering a massive range in front of him. This HHA does not require an initial hit to connect in order to work, and will not stop until it finishes or Wamuu is interrupted.
Wamuu may perform his HHA while Wind Protector is active, regardless of how much of the Heart Heat Gauge he has left. Doing so however, will drop his HHG to zero.
+ 3 ATK Buttons, or 
ON GROUND Wamuu turns his horn into a giant wind-based drill and swings the razor-sharp stream of air to knock the opponent into the air above him. He then rapidly juggles them above his head with the drill as it shapes itself into a Mobius strip. If the initial assault is successful, he then finishes by focusing the drill into his opponent for a powerful attack that sends them flying. This GHA does not require an initial hit to connect in order to work, and will not stop until the first part finished.
Gameplay Overview
A massive fighter whose abilities, including his normal attacks, possess great range and coverage, Wamuu easily outranges most other close-ranged fighters and even matches Stand Users. His tall stature also lets many of his moves to naturally strike aerial opponents as a deterrent for jumping. He may shrug off most incoming attacks while in his various Modes, especially his Wind Protector, which also serves to emphasize his immense power. Wamuu can easily overtake and counter attempts at offense on his opponent's part, even while playing defensively, due in no small part to his sizeable skills. As Wind Protector also grants the ability to use his HHA regardless of cost, Wamuu, like his fellow Pillar Men, can deal massive amounts of damage with only a single stock of Heart Heat.
However, true to his niche, Wamuu suffers from sluggish recovery in his various attacks, leaving himself very vulnerable to retaliation when said attacks are properly blocked or dodged. This is exacerbated in situations where he's forced to play offensively, as he is unable to run, and his forward step (or 'dash'), while covering good distance to compensate, is slower than average as well. Wamuu thus has much greater difficulty closing distance than any other character. His large frame also makes him easier to hit with projectiles and the like, which can make it even more challenging for him to avoid attacks when moving.
Wamuu is a powerful and demanding combatant whose size, armored power, and chip damage potential can allow him to overwhelm his opponent through simple brute force, but requires some thought to avoid getting outmaneuvered and punished. Regardless if he is on offense or defense, once he lands a solid hit, his propensity for damage utilizing even a small amount of Heart Heat is extraordinary.
