In Kingdom Hearts III, Atomic Deluge is the max-level Shotlock of the Hero's Origin Keyblade that requires 16 locks to use. When activated, Sora Formchanges the Keyblade into Counter Shield and thrusts it into a lightning orb, spinning to send lightning all around him. Visually, when using Atomic Deluge, Sora's clothes transform into Guardian Form.
