After Sora, Captain Jack Sparrow, and their friends interrupt Barbossa's ceremonial sacrifice of Will Turner, Barbossa calls on Pete to assist him. Pete provides him some support by summoning an Illuminator Heartless to battle Sora and his friends. It was revealed that the Illuminator has the ability to absorb the moonlight in the chamber, which in turn, makes Barbossa invulnerable to any attacks. Each time an Illuminator was defeated by Sora, Pete would summon another one to take it's place. Eventually, Sora and his friends managed to defeat Barbossa and chase Pete off.
