Captain Hook is the leader of the pirates who sail the waters of Neverland, and Peter Pan's arch nemesis. He appeared in Kingdom Hearts, Kingdom Hearts: Chain of Memories, Kingdom Hearts 358/2 Days, and Kingdom Hearts Birth by Sleep.
 Kingdom Hearts Birth by Sleep
While looking for treasure on the island of Neverland, Hook and Mr. Smee are attacked by a swarm of Unversed, but are rescued by Terra. Hook tells Terra that a young boy has been tormenting him for quite some time, attempting to steal "the light" inside Hook's chest. Terra at first believes that the boy may be Vanitas, but Hook tells him that the boy's name is Peter Pan, and requests Terra to take the chest to Skull Rock and guard it from the thief. Once they arrive, Smee informs Hook of a shooting star which landed not far from where they are. Hoping to find more treasure, Hook leaves the chest in Terra's care and departs to find the shooting star. He finds it, and captures Tinker Bell, as well. Although he is confronted by Ventus, Hook escapes with Tinker Bell and reunites with Terra inside Skull Rock, showing him the imprisoned fairy, who he plans to use to trap Peter Pan.
However, Terra frees Tinker Bell, having learned the truth about Hook during a confrontation with Peter Pan. Just as Hook prepares to engage Terra, the Crocodile appears and Hook makes another run for it. Shortly afterward, Ventus finds him waiting at the Cove, wondering if Peter Pan has been defeated yet. Ven defeats Hook in battle, ending by knocking him into the water, where he is chased off by the Crocodile.
Some time later, when Aqua lands on the island, the Lost Boys tell her that Hook has stolen their treasure once again. Aqua, Peter and the Lost Boys eventually track Hook down, but as Hook gloats, he opens the treasure chest only to find nothing but the Boys' toys and other keepsakes (including Ventus's wooden Keyblade). As he curses, the Crocodile appears and he runs away.
Some time after Master Xehanort's defeat, Hook's hat is stolen by Peter.
 Kingdom Hearts
Ten years later, Captain Hook has joined forces with Maleficent to use the Heartless to defeat Peter Pan. His vessel is used as a transport for Riku to Hollow Bastion. Sora, Donald, and Goofy arrive on his ship in Neverland. They team up with Peter Pan, who is trying to free Wendy, who has been imprisoned on the ship. They do battle with Hook and manage to beat him, throwing him off his own ship and into the water, where the Crocodile chases him off.
 Kingdom Hearts: Chain of Memories
Hook appears as a figment of Sora's memories. Upon meeting the "stowaways" on his ship, Hook reveals that he captured Wendy and is using her as bait to lure Peter Pan to his doom. However, Peter Pan does arrive and saves Wendy. Hook nearly falls into the ocean when he goes after the hero, but he stops himself just in time and fights against Sora in rage.
Hook also appears in Riku's memory-worlds as a token of the indelible darkness within him.
 Kingdom Hearts 358/2 Days
Captain Hook and Smee are once again digging around the island, searching for treasure. However, instead of treasure, they find Heartless, who are attracted to Captain Hook's greed. Eventually, it is revealed that Pete is the mastermind behind it. Pete had created a series of maps leading to the Heartless, hoping to turn Hook into a Heartless. When Smee digs up the final hole, Captain Hook is ecstatic that this one has real treasure. Just when he is about to collect his rewards, Pete turns the treasure into a Heartless. Luckily, Roxas is there to dispatch the giant Heartless, allowing Captain Hook to escape to his ship. In the end, however, his greed comes full circle when the Heartless crashes into his ship.
Captain Hook is very arrogant and full of himself, and gets angry if someone insults him. He tends to hold a grudge against Peter Pan for stealing his hand and feeding it to the crocodile. He is an excellent manipulator and liar. An example of this is when he manipulated Terra, in Kingdom Hearts Birth by Sleep. He is cowardly and sometimes acts like a wimp, particularly when he hears the sound of the Crocodile coming close by. However, he is also an excellent sword fighter and a bomb expert, making him a challenge in combat.
Captain Hook is a thin man with curly, black, shoulder-length hair that drapes over his shoulders, a large, hooked nose, a thin, black mustache that angles upward sharply, and a large chin. He wears a frilly, white shirt underneath a red coat with gold lining and maroon cuffs. Each of these cuffs sports two yellow buttons. He also wears an orange sash over his right shoulder that holds his sword scabbard at his left hip. Hook wears maroon pants and white, knee-high socks, as well as black shoes with a pink circle decorating each one. The tongues of his shoes are enormous, reaching halfway up his shins. He wears a large, maroon hat with a huge, white feather stuck in it. He carries a rapier with a gold handle and guard as a weapon.
In the original book, Captain James Hook was the Pirate Captain of the Jolly Roger. His origins are all but unknown, only showing that he was a school teacher and a sword champion before his life of crime. Hook came to Neverland because he thought that there would be treasure, and he was right as the book makes reference to Peter Pan and the Lost Boys having fun by stealing his treasure and making him find it all over again. Hook also made references to "Good Form", something he picked up in his teaching days. When ever he fights Pan, he always tries to make the fight to "Good Form" as a habit. But when the fight gets slower, he will try to win by tricking Pan. Peter would call him on it by saying "Bad Form", but Hook would always find a way of making it good again, usually by saying his life was at risk. One point that the game doesn't use is how cruel Hook really is. This point is made both in the book and in the 1953 film, when Hook shoots one of his men. The Disney film made this a little child safe by making Hook get annoyed with his singing. In the book, Hook just shoots him out right, just to have a little fun.
