Captain Jack Sparrow is a crafty and potentially dangerous pirate who inhabits Port Royal. After being freed from jail by Will Turner, he sets off to reclaim his stolen ship, the Black Pearl, which was taken over by Captain Barbossa.
Upon meeting Sora, Jack becomes available as a party member, and fights alongside him during both Port Royal visits. He eventually falls under the curse of the medallions, and has to break free from its spell.
Sparrow's trademark physical characteristic is a slightly drunken swagger, accompanied by slurred speech and awkwardly flailing hand gestures that make him appear unfocused. But he's actually a decent, if self-serving, man who adheres to the "Pirata Codex".
He believes pirates can still be "good men", seeing the Heartless causing trouble give real pirates a bad name. Though both deny it, Jack and Sora have similar personalities as both are loyal to their friends. His drunkard-like persona doesn't mean anything when the fight comes.
He also prefers to be called "Captain Jack Sparrow" or "Captain Sparrow".
Jack Sparrow is designed in the likeness of his actor in the film, Johnny Depp; a tan, mustachioed man who wears his dark brown hair in dreadlocks and braids decorated with numerous beads and coins. His beard is similarly styled into two smaller braids, each with two very small beads near the tips. Jack wears a faded red bandana on his head, on which is another small beaded ornament ending in a silver coin. He wears brown boots and has brown eyes covered in kohl, and carries a scabbard off his cutlass on his left hip, kept in place by a black baldric that goes over his right shoulder.
He wears another, tan belt around his waist, overtop a tattered, white and red piece of cloth tied around his waist. Jack's compass hangs from this second belt, tied on by a piece of twine, and his pistol is tucked into the cloth. He wears a faded, loose white shirt underneath a faded blue waistcoat that exposes his chest, both tucked beneath the cloth and belt. The legs of his grey breeches are tucked into his boots. Finally, Jack sports a fingerless glove on his right hand.
Strangely, in Kingdom Hearts II Jack doesn't wear his hat, even though it was repeatedly shown to be precious to him in the films.
Under the effects of the curse, when under moonlight, Jack's body becomes that of a rotted skeleton. Though more or less the same, Jack's clothes become far more tattered, to the point that he altogether loses most of the legs of his pants. His skin becomes grey and rotten, and the decay of his lips exposes three gold teeth in the front of his mouth.
Following the plot of Pirates of the Caribbean: The Curse of the Black Pearl, Jack Sparrow was arrested for piracy on Port Royal while attempting to steal a ship to go after the Black Pearl. But after Barbossa took Elizabeth Swann, Will Turner reminds Jack of the debt for freeing him, so the two, together with Sora and gang, hijack the HMS Interceptor to go after the Black Pearl.
While Sora and gang had to stand guard, though they worried the two couldn't fight the Heartless, Jack and Will infiltrate the cave on Isla de Muerta, where a ritual is underway with Elizabeth, whose blood Barbossa believes will break the curse. Mistrusting Jack, Will knocks him unconscious. He rescues Elizabeth, and the two escape to the Interceptor, with Jack captured and tied to the mast on the Black Pearl.
After a fierce battle between Sora's gang and the Undead Pirates, the Interceptor crew is captured. After learning Will can break the curse, Barbossa left some Heartless and kegs of lit gunpowder to leave Sora and gang to their fate. But the heroes managed to overcome the odds and returned to the island and rescued Will.
Jack more than matches the ruthless captain blow for blow. While Jack is momentarily distracted, Barbossa impales him with his sword, believing he is mortally wounded. However, when he stumbles backwards into the moonlight, Jack is revealed to be under the curse, having sneaked a coin from the chest to curse himself while Sora and gang dealt with Barbossa's cursed crewmen.
Jack and Will lift the curse just after Jack fatally shoots Barbossa with the shot he has carried for ten years. No longer immortal, Barbossa falls onto the ground, dead. Though Will offered his hand to Jack, he took a step back in fear Will might hit him again. Jack's compass was then used to open up new routes with Sora's Keyblade.
On Sora's return trip to Port Royal they discover that there are still cursed pirates in Port Royal. Jack and his crew journey to Isla de Muerta aboard the Interceptor, saving Will from a certain death, and on the way come across a member of Organization XIII, Luxord, who has stolen the chest with the cursed medallions and summons a giant Heartless to fight them. Upon defeat, Luxord calls for parley by throwing out four pieces of treasure to Gambler Nobodies and destroying the Interceptor with the Black Pearls armament.
After landing in the Ship Graveyard, the crew discovers that the curse has come back to Jack. The group hunts down the four stolen medallions, and eventually find them.
Back at Port Royal, Luxord is there waiting for them to return the treasure. After it is returned, he summons the Heartless from before who is now under the curse. When they return the medallions, the curse on the Heartless lifts, but Jack's skeleton form remains. Goofy immediately realizes that Jack has been put under the Heartless' spell rather than the gold's curse.
After the Heartless is destroyed, the curse is lifted for good. The chest is then dumped into the sea to ensure that the curse does not ever resurface. As a reward for his trouble, Jack asks for Sora's Keyblade. Knowing the Keyblade would return to him, Sora agrees to it. When it vanishes back to Sora's hand though, Jack is not surprised. Jack vows to one day get a bloodthirsty crew together and steal the Keyblade.
The story ends with Sora, Will and Elizabeth commenting on Jack being the best pirate in the Spanish Main, no, the whole ocean.
The end credits show Will and Elizabeth on the Black Pearl. As Jack sails, the moon comes out and he checks his hand, still remaining human.
Jack is primarily an offensive party member, using his sword to attack and also throwing bombs and knives at enemies. As such, his fighting style is somewhat similar to Aladdin's, although he is slower and has the aforementioned projectile attacks. He also has several support abilities, especially Draw. Jack has one armor slot, one accessory slot, and four item slots. Jack's abilities are as follows.
- No Mercy: An inescapable sword attack.
- Rain Storm: Jack throws knives at enemies.
- Bone Smash: Jack throws bombs in groups of three several times.
- Treasure Isle: Activates the Limit, Bluff. Sora and Jack draw enemies in for combination attacks.
Captain Jack Sparrow originally appeared in the 2003 film Pirates of the Caribbean: The Curse of the Black Pearl, portrayed by Johnny Depp. In that film, Jack's role is similar to his role in the first visit to Port Royal in Kingdom Hearts II.
- Because Jack Sparrow and Jack Skellington have the same first name, Jack Sparrow is called "Captain" by the party instead. In the Japanese version, he is called "Sparrow".
