Mushu from KH II
After slaying the Dragon Maleficient, Sora found a fireglow gem. Sora transported himself to the Fairy Godmother, where she managed to restore him. Mushu's homeworld was demolished by the heartless, but Mushu's heart was so powerful he was turned into a stone. After he was restored, Mushu teamed up with Sora and together they torched many heartless. You can obtain the Mushu summon in Hollow Bastion. When summoned, Mushu appears on Sora's head and blasts heartless with fire.
