King Boo's Illusion is the final level/area in Luigi's Mansion: Dark Moon.
History[]
After defeating the Tough Possessor in the Treacherous Mansion, Luigi gets pixelated, but back at the lab, when Professor E. Gadd expects Luigi to come out of the pixelator, only the Dark Moon shard comes out. You then see Luigi's pixels surrounded in a purple aura. Then his pixels bump into each other to make Luigi, then Luigi falls to the ground of a dark room. Then he hears King Boo and certains open to reveal many windows and a picture of Mario can be seen. Then the battle starts.
