The Undead Pirates are enemies that appear in Kingdom Hearts II. They are the crew members of the pirate ship, The Black Pearl, and helped first mate Barbossa mutiny Jack Sparrow, their former captain, and steal the cursed Aztec gold of Isla de Muerta. After Barbossa's death, the remaining pirates allied with Luxord during Sora's second visit, who granted their immortality back to them. They appear throughout Port Royal as generic enemies.
The Undead Pirates originated from the Disney film Pirates of the Caribbean: The Curse of the Black Pearl.
 Kingdom Hearts II
During Sora's first visit to Port Royal, they serve alongside Captain Barbossa on his quest to lift the curse set upon himself and his crew, displaying their punishment for stealing the Aztec treasure before Pete when he warns the crew about Sora and his friends. The cursed pirates then proceed to attack Sora, who soon arrives with Donald and Goofy. They aid Barbossa in destroying the Interceptor, also present when he kidnaps Elizabeth Swann and attempts to use her blood to lift the curse.
The Undead Pirates also appear during Sora's second visit to Port Royal, having a much less significant role than during the first visit. They appear as normally encountered enemies again, still cursed.
The Undead Pirates don't talk, so not much is known about their personality. They are loyal to their captain Barbossa and they follow his orders.
The bald, dark-skinned Undead Pirate A is modeled after the original film's Bo'sun, though the Bo'sun had somewhat darker skin, as well as numerous piercings and tattoos. He carries two hatchets as weapons. This pirate is shirtless, wearing only brown boots, baggy, tan pants, a brown belt, and a tan sash on his left hip. Unlike his fellow pirates, when under the influence of the curse, this man's clothing remains unchanged. Though he himself becomes a skeleton, his clothes are entirely unaffected.
Undead Pirate B, modeled after the movie character, Twig, wears a loose-collared white shirt, an orange ascot, blue denim pants, a brown belt, brown boots, and a tan, unbuttoned coat. He carries a crossbow (a gun in the original Japanese version) for a weapon. This pirate also sports a short, brown beard and an orange bandana. Under the influence of the curse, he becomes a skeleton in tattered, worn clothing, notably losing the lower half of his right sleeve and his left pant leg.
Undead Pirate C, based appearance-wise on the movie character, Jacoby, carries both a knife and a supply of bombs as weapons. He wears dark, baggy pants, a brown belt and boots, a loose, white shirt, and a grey vest. He also wears an odd white and red hat. He has a long, grey beard styled into dreads and tanned skin. Under the influence of the curse, this pirate becomes a skeleton and his clothes become tattered and worn. His clothes are more damaged than his fellow undead pirates, as he loses most of both legs of his pants and his left sleeve.
The Undead Pirates from Port Royal come in three different varieties, each with differing and similar abilities. All Pirates, for example, are invulnerable unless exposed to the moonlight and are very susceptible to Elemental magic (Fire, Blizzard and Thunder). Each type of Pirate has a different way of attacking:
The Undead Pirates originally appeared in the 2003 film Pirates of the Caribbean: The Curse of the Black Pearl. In that film, the role of the Undead Pirates is similar to their role during the first visit in Kingdom Hearts II.
