In-Game Description
''King Boo has created the ultimate illusion and he's waiting for you to show yourself. are you brave enough to face him in his own territory once again?''

History
After Luigi stabilizes the worlds dimension he enters the portal to find the last Dark Moon piece. Upon arriving Luigi winds up in a large room with knight statues. Here Luigi battles the Tough Possesor which posseses multiple suits of armor and a Gigantic suit of armor as a last attempt to defeat Luigi.

Apon defeating the Tough Possessor, Professor E.Gadd tries to pixelate Luigi out, to meet him in the Bunker. However, the transmission is intercepted by King Boo, and Luigi placed back into the illusion world. King Boo then starts taunting Luigi by making windows visible, where the player can see King Boo's silhouette outside, and laughing at him. After the taunting, Luigi looks up, only to see Mario trapped in a painting. He reaches out, but King Boo appears behind the painting, which turns out to be a illusion. He then starts talking to Luigi, about his incarceration in a painting and about his escape. He then announces that "he returned to paint the town red" and become the supreme ruler of the Mushroom Kingdom. He then accumulates energy from his crown, and reveals the arena for Luigi and King Boo's battle.



Battle
In the 1st phase of battle, King Boo will summon 3 spiked balls which will land heavily on the ground from high above. The place where that will land is predictable because of the shadows they cast before landing.

After defeating King Boo, Luigi picks up his power-enhanced crystal which returns him to the Terrace where Mario's painting was all the time, hidden by Spirit balls, that disappered after King Boo's defeat.
