The Worlds
---
Wonderland, from Alice in Wonderland. This is a surreal level in which the player is shrunk down to a miniscule size. This is the first level that can be closed to the Heartless. It features the Cheshire Cat, the Doorknob, Alice, The Queen of Hearts, and several cards as well as the White Rabbit.
---
Olympus Coliseum, from Hercules. This includes Hades, Hercules, Philoctetes (a.k.a. Phil), Cerberus, and Cloud Strife.
---
Deep Jungle, from Tarzan. This is a slightly longer world than the first, and includes Tarzan, as the first character that can be added to your party, Jane, Clayton and several gorillas.
---
100 Acre Wood, from Winnie the Pooh. This world is unlike the others; there are no Heartless here and it takes place in the pages of a book. A variety of mini games open up as you proceed through the game.
---
Agrabah, from Aladdin. This world includes Agrabah and the Cave of Wonders. Aladdin, Abu, Jasmine, Jafar, Iago and Genie are introduced here, with Aladdin being a possible party member.
---
Monstro, from Pinocchio. This world brings the player through the bowels of a whale. The infamous little wooden puppet Pinocchio and his maker Gepetto can be found here. Monstro is not a true world by Kingdom Hearts' definition, and thus does not contain a keyhole to be sealed.
---
Atlantica, from The Little Mermaid. This was a distinctive underwater level that consists of Ursula's cave, several grottos, and the city of Atlantica. Ariel, King Triton, Ursula, Sebastian, Flounder, Flotsam and Jetsam appear in this world, with Ariel being the only female character in the game to join your party. This level has often been criticized by fans as a difficult level to play because the controls vary underwater.
---
Halloween Town, from The Nightmare Before Christmas. The movie's cast make their video game debut in the level. This world includes the town square, Oogie Boogie's Manor, Moonlit Hill and a graveyard. It features Jack Skellington, Sally, Lock, Shock, Barrel, Doctor Finklestein, Zero, the two-faced Mayor and Oogie Boogie, with Jack able to join your party.
---
Neverland, from Peter Pan. The world's name is somewhat a misnomer because the action takes place on Captain Hook's ship and a minor bit in London; as such, the actual Neverland is not actually visited. Captain Hook, Peter Pan, Wendy, Smee and Tinkerbell call this world home, with Peter Pan able to join your party. It is also one of the more important Disney-based worlds in the game, storyline-wise.

The original worlds:
---
Destiny Islands. This is where the Sora starts his journey, and although only accessible near the beginning and end of the game, the islands and the events in them are critical to the entire game's storyline. This world is home not only to Sora, Riku, and Kairi, but also Final Fantasy characters, Selphie Tilmitt, Tidus, and Wakka.
---
Traverse Town. A sort of "resting place" to come back to in between worlds, Traverse Town is where Sora first meets Donald and Goofy and truly starts his quest. Several Final Fantasy and Disney characters reside here, including Aerith Gainsborough, Gepetto from Pinnochio, Yuffie Kisaragi, Squall Leonheart, Cid Highwind, and Merlin from The Sword in the Stone.
---
Hollow Bastion. This is the world that has been created for the Square characters as well as a sort of stand-in for the movie Beauty and the Beast as the Beast is a playable character there. This is also Maleficent's headquarters.
---
End of the World. A large, dark world created from the assimilation of various worlds consumed in darkness. It is where many Heartless and evil beings reside. Kingdom Hearts is near the center of this world. The final battles with Ansem are fought here. The World Terminus is located here, providing access to small areas of other worlds.
---
Disney Castle (non-playable)The homeland of Mickey, Donald and Goofy.
