Shrewd Possessor

The Shrewd Possessor (Scornful Possessor in PAL) is the fourth boss Luigi faces in the Nintendo 3DS game Luigi's Mansion: Dark Moon. He is first encountered in the Secret Mine's Workshop where he is seen trying to harass a Fuzzball. When Luigi faces the Possessor, he will take control of the frozen ground below him, in an attempt to escape with the Dark Moon piece, causing Luigi to chase it down the pit. The Shrewd Possessor holds the fifth Dark Moon piece.

Appearance
When possessing ice, the Possessor resembles a large, icy face with a big jaw and two gray eyes.

When not being shielded by ice, the Shrewd Possessor is thin, white, multilayered skin ghost. This Possessor has four horns: two horns that curve outward and a horn on each of those horns that protrude sideways.

Battle
The Shrewd Possessor will not directly attack Luigi. Instead, it will spiral down the Frozen Pit clockwise while shielding itself with ice sheets. If Luigi destroys the ice shield, it will stop spinning and attempt to eat Luigi.

While not possessing the ice, the Shrewd Possessor will try ramming his face into Luigi three times. Unlike the previous Possessors, this Possessor travels randomly through portals. After its third charge, it will be stunned momentarily. It is possible for Luigi to stun it and start capturing it before it can attack.

Unlike previous battles, Luigi will be sitting atop the Bomb Sled. The Possessor will protect itself with ice sheets. These sheets must be destroyed using the machine. Each time a bomb is used, the Bomb Sled overheats slightly, and the Possessor moves down further. The Possessor is invincible even if it's hit with a bomb. The only way to damage the Shrewd Possessor is to destroy all the ice sheets protecting him. This will cause him to fly into a rage and attempt to eat Luigi. During this time, his mouth will be open. If a bomb is shot into the Possessor's mouth before he can hit Luigi, the bomb will destroy the ice protecting the boss and reveal his true form. If the Possessor's charge comes in contact with the machine, it will significantly overheat. If the Bomb Sled overheats, Luigi automatically gets a Game Over. If Luigi takes too long destroying the ice sheets or keeps missing, the possessor will fully rebuild the broken ice sheets. The Bomb Sled will not cool down from this. With each phase change, though, the machine goes back to normal and the Shrewd Possessor will get an extra sheet of ice protecting his face. Repeating this process three times will earn Luigi a victory.

Trivia

 * When Luigi is watching the Possessor in the workshop for the first time, oddly he doesn't have the Dark Moon piece in him. This could either be an accident, or King Boo hadn't given him the piece yet.
