Phantom Storm

Phantom Storm is the third Gummi Mission available in Kingdom Hearts II. Upon completion the first time through, it unlocks Olympus Coliseum for regular gameplay.

Unlike most of the other Gummi Missions, Phantom Storm revolves around fighting one massive creature (a giant 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.

Mission 1
This medal collecting mission is considerably easier than the previous missions due to a massive Heartless enemy, the Pirate Ship. This Pirate Ship has many components, giving opportunity for many points and higher medal rankings.

The mission starts with the Gummi Ship charging through a green tunnel filled with white and blue buildings. Easily dodge the buildings to prevent damage. Shortly into the mission you will encounter a group of Knight Heads. Quickly dispose of the red Knight Heads to earn extra points. After dispatching the Knight Head enemies, an alert will sound, forcing the group to focus on an approaching ship. This ominous ship is the Pirate Ship, and will take up the bulk of this level. Once your fight with the Pirate Ship begins, immediately start attacking the large shaft found on the first large wheel. Not only will this raise your score just by hitting the shaft, but if you destroy the shaft and wheel entirely, you will be rewarded with a large amount of points, enough to jump up two medal rankings. As you continue around the ship, you should destroy its components to rack up points. Also, dispose of the occasional ghost and ghoul enemies that appear. While they aren't as dangerous as other enemies, they can easily surround the Gummi Ship and hinder your process. As you reach the right side of the ship, quickly destroy the numerous medium sized cannons. These cannons will fire cannonballs that will explode shortly in front of the Gummi Ship, damaging and knocking the ship across the screen. The larger mega cannons will fire regular cannonballs. As you finish rounding the Pirate Ship, the metal shield protecting the skull will open, allowing you to damage the ship directly. While you attack the skull many Grapplers will appear and grab hold of your ship. Dodge Roll to cast them aside, but still continue to attack the skull. The skull will continuously release ghoul enemies to delay its destruction, dispose of both to earn a handsome point reward.
