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.
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.
Rage Form is a swift and powerful Formchange, though Sora cannot use magic, Links, or items while in this Formchange. Team Attacks can still appear and be used, which will revert Sora to his normal form. 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 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, raising his Strength and enhancing the properties of certain attacks such as his combo finisher at the cost of depleting half his remaining health. After using Riskcharge three times, Sora gains access to Rage Form's finish command, which consists of Sora plunging the Keyblade into the ground and submerging 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 Focus orbs that can fill the situation meter. Obtaining enough Focus 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.
When guarding in Rage Form, Sora will use a shadowy form of Barrier.
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 does not trigger a retaliation from them from comboing as quickly as when comboing them outside of Rage Form, so if you start a second combo immediately, you can land a nearly full or a full second combo on them before they retaliate.
