Removed content in the Kingdom Hearts series

In the Kingdom Hearts series, a number of contents has been removed due to different circumstances. Some are able to be found within the code of the game, and some others can be accessed through the use of cheat codes.

The Disney Castle world
The world was originally set to appear in the game but was removed. It can still be visited through the use of cheat codes

The Crumbling Island area
The area was originally set to be in the End of the World as the final battle area for Sora and Riku. The are is the remnant of Destiny Islands which was consumed by the darkness.

Awakening
The Awakening was set to appear in the game but was finally removed.

The Jungle Book world and Jungle King Keyblade
The Jungle Book world was set to appear in the game, along with its Keyblade, the Jungle King, but was removed due to copyright issues.

The Edge of Ultima and Detection Saber Keyblades
Through the use of a cheating device, two palette swaps of the Ultima Weapon can be obtained in Kingdom Hearts II. These are the "Edge of Ultima", a version of the original Ultima Weapon with a glitched appearance, and the "Detection Saber", a palette swap of the original as well, except slightly larger. When these Keychains are accessed in Sora's Items menu, no picture of the Keyblades are shown, only map icons.

Alternate Xemnas final boss battle
Instead of using a Dragon, Xemnas was intended to use a "King" form and a "Centaurus" form. Both of them appear as gigantic creatures made from the buildings in the Dark City.

Buzz Lightyear and Woody summons
Buzz Lightyear and Woody, characters from Pixar's Toy Story series, were at one point planned to appear as new summons in Kingdom Hearts II Final Mix. Their models still appear within the game coding.
