The Heart of Atlantis is a very powerful artifact that the friends would want. Fortunately, much like Neverland, their evil magic cannot touch it. So they find a fitting military man to go in and snatch it for them, playing to his greed in order to get things done. Things were going very smoothly before Milo's interference and his getting the Heart back. During that battle, being cut by the crystal-energized glass mutated Rourke into a crystal heartless version of himself, only to be destroyed before he could make his first attack. The Friends decided recruit Crystal Titan Rourke as a heartless commander in battle.
