Elizabeth Swann

Elizabeth Swann is the daughter of the governor of Port Royal. Weak though she appears to be, nobody has any idea what she is truly capable of.

First Visit
Elizabeth is first captured by the undead pirates and taken away because she tells them that her last name is Turner. Sora and company comes to Port Royal just as she is being taken prisoner and tries, but fails, to rescue her.

Later Sora, Donald, and Goofy help Jack Sparrow and Will Turner command the Intercepter, the fastest boat in the British Navy. With it, Sora and friends rescue Elizabeth and, after some complications, defeat Captain Barbossa and the undead pirates.

Second Visit
Elizabeth reappears on the Black Pearl during Sora's second visit to Port Royal. She alerts the party that Will has gone missing and sets out to find him with them. Eventually, they find him on the Interceptor and manage to save him. Thereafter, Sora and the others get attacked by Luxord's Nobodies and Heartless and get blown to another ship, which is later destroyed.

Elizabeth, Sora and friends along with Jack work together to find them and later, the medallions and succeed.

She doesn't reappear untill Sora finds all the medallions and right before the second battle with the Grim Reaper heartless.

After the battle, she helps get rid of the Aztec treasure and agrees with Jack to join his crew.
