Bug/GlitchIn the Olympus Coliseum world, there is a Heartless, one of the game's main enemies, that goes into a T-stance (a pose characters are in during development). This glitch could possibly be due to bad placement, meaning that it could have moved a short amount from where it originally spawned.
ReferencesThe Rock Titan, from the Disney movie Hercules and an optional boss in the original Kingdom Hearts, is seen only once in the entire game (Olympus Coliseum's intro). It's not possible to see or fight him at any other time in the game by normal means. The Ice Titan, who was also in the first game and Hercules, makes no appearance at all.
Two Behemoth Heartless, the huge, purple, mammoth/bull-like creatures from the original Kingdom Hearts were going to be in the 1000 Heartless War, but were cut for unknown reasons.
Suicide attemptIn the Japanese release of the game, in the level Port Royal, the character Will Turner points his gun to his head and attempts to commit suicide. For obvious reasons, this was removed from all other versions of the game, although another cutscene, which depicts a sword pierced through someone's chest, was left intact. Other changes for the American and English versions of the game include differences in the battle with Xigbar, on the final level, where his "shooting scope" is brighter and more accurate to see.
