In Kingdom Hearts III, Diving Barrage is a max-level Shotlock associated with the Shooting Star Keyblade, requiring 18 locks on a single target to use. When activated, Sora Formchanges the Keyblade into Double Arrowguns and fires a barrage of bullets on the target from above. Visually, Sora's clothes transform into Element Form when using this Shotlock.
