Template:Location-infobox King Boo's Illusion is the final area in Luigi's Mansion: Dark Moon. It is where Luigi battles King Boo. Upon defeating the Tough Possessor from the Paranormal Dimension for the first time, Professor E. Gadd tries to pixelate Luigi out, to meet him in the Bunker. However, the transmission is intercepted by King Boo, and Luigi is placed back into the illusion world, automatically starting the next mission, A Nightmare to Remember. After completing the game's story mode once, King Boo's Illusion will be available on the mansion select screen.

Trivia
- During the intro cutscene to this nightmarish place, Luigi is confronted by the portrait of Mario while accompanied by a remix of the classic Super Mario Bros.Music, however as Luigi slowly approaches the portrait, King Boo moves the portrait away to frighten Luigi (and first-time Players).
- The scene where Luigi is supposed to run down a long pathway with King Boo rolling behind him, attempting to crush him is a reference to Indiana Jones, where Indiana Jones is seen running from a giant boulder.
