Here I will show you the Disney Characters that don't play a major part in the story.
Aladdin...
The hero from the movie Aladdin. In Kingdom Hearts, Sora and Co. helped him find the captured Princess of Heart, Jasmine from the clutches of Jafar and Maleficent. He is back for this game.
The princess of Atlantica who Sora, Donald, and Goofy helped out in the first game when she mistakingly gave Ursula her father's Trident. She returns in this game as a sort of sing-song minigame world.
In Kingdom Hearts, Beast teamed up with Sora to help him fight through Hollow Bastion, and Sora in turn helped him find Belle. In this game you travel to his castle where things are not well.
Belle was one of the seven Princesses of Heart in the first game that were needed to open the final keyhole. In this game you travel to Beast's Castle where she lives and Xaldin is disturbing the peace.
From Pirates of the Caribbean, Barbossa is the man who betrayed and left Jack Sparrow for dead on a stranded island. He and his crew found the lost treasure of Cortez which, little did they know, had a deadly curse.
From Pirates of the Carribean, Jack is probably my favorite Disney Character. He is a lazy and greedy pirate that would like nothing better than to have his ship, the Black Pearl, taken back from Captain Barbossa.
She was seen very shortly in the original Kingdom Hearts, during the scene where Donald and Goofy left. She is helping Minnie look after the castle in Mickey's absence.
The main female character from Pirates of the Caribbean. She is believed to be the one the pirates need to break the curse, but it turns out to be someone else...
Jafar was second-in-command in Maleficent's circle of Disney Villians in the first game. He was trying to kidnap Jasmine because she was one of the Princesses of Heart that they needed. Sora, Donald, Goofy, and Aladdin fought and sealed him inside his own lamp after he commanded the Genie to make him a Genie as well. Though it seems Pete has found Jafar's lamp...
The Queen of Disney Castle, she is looking after it in Mickey's absence. She was seen very briefly in the original Kingdom Hearts, but you travel to Disney Castle and see her in this game.
The current king of the Pridelands, uncle to Simba, and murderer of Mufasa. Scar is a cunning foe who has takn control of the Pridelands in Simba's absence.
Rightful king of The Pridelands and companion of Sora from the first game. Simba is afraid to face Scar and the memory of his past, as he believes that it is his fault his father [Mufasa, the previous king] died and that Scar has now taken control of the Pridelands.
The Destroyer of Evil Programs, Tron is from the movie...Tron. He teams up with Sora, Donald, and Goofy when they make a visit to his world, Space Paranoids.
The villain of Atlantica who conspired with Maleficent in the first game in her plan to control the Heartless. She nearly succeded in taking over Atlantica as well, before Sora and friends got there.
