Rage Form

Rage Form is a Formchange in Kingdom Hearts III. It has a chance to activate when Sora reaches critical health, regardless of current Keyblade.

Kingdom Hearts III
During Sora's final fight against Master Xehanort in Scala ad Caelum, Xehanort uses the power of Kingdom Hearts to steal Sora's light and force him into Rage Form. By attacking Xehanort, Sora eventually regains his light.

Design
Rage Form turns Sora's clothes, skin, and Keyblade deep black, with glowing red eyes, an aura of darkness, and a fluorescent white swirling pattern on his pants. It is similar to AntiForm and envelops Sora's Keyblade in darkness for quick and powerful attacks. While AntiForm represents Sora overcome by darkness, Rage Form represents Sora's anger.

While in his Kingdom Hearts II attire, Sora's appearance in Rage Form is identical to AntiForm.

Mechanics
Rage Form is a swift and powerful Formchange. While Sora cannot use magic, items, and Link Summons in Rage Form, he can still use Team Attacks, which will revert him to normal. Rage Form's combos are aggressive and swift, allowing a powerful offense, and consist of Sora combining darkness-infused Keyblade slashes with scratches and kicks. The combo finisher has Sora surround himself with a barrage of slashes before erupting an orb of darkness from his body.

While in Rage Form, Sora can use the Riskcharge Situation Command, which depletes half of his remaining health while raising his Strength and adding additional properties to his combos, such as shockwaves of darkness to his normal attacks and tendrils of darkness to his combo finisher. Every time he uses Riskcharge, Sora will be surrounded by a red wisp of darkness. The Finish command, which will appear after using Riskcharge three times, has Sora plunge the Keyblade into the ground and submerge the area around him in darkness. Orbs of darkness surround Sora before generating spikes and spinning around, delivering massive damage.

During the final fight against Xehanort, Rage Form does not have a time limit, and Sora cannot use Riskcharge. Instead, Sora must attack Xehanort to make him drop orbs of light that can fill the situation meter. Obtaining enough orbs will unlock the Return to the Light Situation Command, in which Sora repeatedly rushes at Xehanort before diving at him and regaining his light.

Abilities
When guarding in Rage Form, Sora will use a shadowy form of Barrier. He can use Raid as a counterattack, in which he throws the Keyblade and hits the enemy multiple times.

Strategy
Rage Form is the only Formchange available that replenishes Sora's HP upon activation, making it useful when in low health situations. However, as it locks the use of magic, Links, and items, be sure to have Donald ready to heal Sora.

Against humanoid foes, Rage Form's combos do not trigger a retaliation from them as quickly from other combos. This means it is possible for Sora to land a nearly full second combo on them before they retaliate.
