Battleships are large galleon-like Heartless that fly in the air via propeller. What looks to be a Heartless captain on it is actually its head and top half of its body. One of the most complicated Heartless, Battleships seem to be composed of two main parts. At the wheel of the ship is a Heartless captain, blue in color and wearing an eyepatch, black pirate hat with a skull on the headband, white gloves, and a blue admiral's jacket with red and gold trim.
The ship itself is a bit more ornate; while made of what appears to be ordinary wood, it is decorated in bright pink and purple and features a prow covered in horns, a skull figurehead, and a cannon with a sharp spike as ammo at the very front. On the left hand side, just behind the prow, is the ship's spiky anchor. Two smaller cannons sit on either side of the ship further back. Although the ship appears to be powered by wind, as seen from the black sails, giant propeller on the mast, and two smaller propellers on the stern, the ship also has two grey oars jutting from the sides.
The Kingdom Hearts Final Mix recolor makes for a much wilder looking ship; it is now painted a bright pink color, the horns are black, and the trim and sails are white.
The Battleship bears a slight resemblance to the Pirate Ship Gummi Heartless.
The Battleship's name and design are references to battleships, notably ones used in the pre-nineteenth century. Like the Heartless, these ships had sails and used cannons as a main form of attack.
Battleships are some of the most powerful non-boss type enemies in the game, and are in the same ranks as the Devastator enemy in Kingdom Hearts II. Due to its massive HP pool and the difficulty involved in reaching it if encountered outside of Neverland where flight is unavailable, a Battleship can prove to be a persistent threat.
The Battleship's attacks don't cause major damage, but may be deadly if Sora is low on health, and its arsenal allows the Battleship to attack Sora from far outside his range.
Certain parts on the Battleship can be destroyed, crippling it. For example, the cannons can be destroyed to halt its rocket fire or the mast (the sail and top propeller) can be destroyed to limit its ascent and keep it from dropping bombs. Sora doesn't have to destroy all the parts to defeat a Battleship, but he does get Tech Points for each part destroyed. Gravity Magic can deal great damage to the main body and at the same time instantly destroy the mast. If both cannons and the mast of a Battleship are destroyed, the charging attack will be the only ability left that it can use.
If there is at least one other enemy in the fight who has missing HP, and the Battleship has at least one operational cannon, it can attempt to heal them by lining itself up and firing a large green healing rocket straight at them. If Sora or a party member can intercept this rocket directly, then their own HP will be replenished.
