Mundos

Além dos mundos tradicionais de Kingdom Hearts, existem outros mundos adicionais.

• Twilight Town
• Hollow Bastion
• The World That Never Was
• Disney Castle
• Beast's Castle
• Olympus Coliseum
• The Land of Dragons
• Timeless River
• Port Royal
• Agrabah
• Halloween Town
• Pride Land
• Space Paranoids
• 100 Acre Wood
• Atlantica

No entanto, alguns mundos foram retirados. Hollow Bastion mudou muito, e tornou-se praticamente o mundo principal, empatado com The World That Never Was e Twilight Town, já citado. Hollow Bastion depois de completado, torna-se Radiant Garden.
