In Kingdom Hearts III, which world is based on the Pixar film Monsters, Inc.?

In Kingdom Hearts III, the world based on Pixar’s Monsters, Inc. is Monstropolis.

Monstropolis brings Sora, Donald Duck, and Goofy into the monster-filled setting of the 2001 Pixar film. Players encounter familiar characters including Sulley, Mike Wazowski, Randall, and Boo, while exploring locations inspired by the movie’s factory and city environments.

The world’s story takes place after the events of Monsters, Inc. Rather than simply replaying the film’s plot, Kingdom Hearts III creates a new adventure involving the Unversed-like threats and the Organization XIII conflict. This approach lets the game use the film’s cast and visual identity while continuing its own larger storyline.

Monstropolis is often confused with Toy Box, another Pixar-based world in Kingdom Hearts III. Toy Box is based on Toy Story, while Monstropolis is specifically the Monsters, Inc. world. Kingdom Hearts III was notable for introducing both Pixar settings to the series.
