Rage Form

Rage Form is a Formchange in Kingdom Hearts III. It is similar to AntiForm and envelops Sora's Keyblade in darkness for quick and powerful attacks. It has a chance to activate when Sora reaches critical health, regardless of current Keyblade.

Appearance
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.

Mechanics
When in Rage Form, Sora can use Riskcharge as a situation command, raising his Strength, at the cost of depleting half his remaining health. After using Riskcharge three times, Sora gains access to Rage Form's finish command.

Strategy
Entering Rage Form replenishes Sora's HP so it is useful when in low health.
