Unlike most of the other Gummi Missions, Phantom Storm revolves around fighting one massive creature (a huge Pirate Ship) with several components. In Kingdom Hearts II Final Mix, the EX S mission requirements are: * Mission 1: Must use a pre-made Highwind ship. * Mission 2: Gummi ship can have 50 HP at most. * Mission 3: Gummi ship can have 20 HP at most, including teeny ships.
