Harsh Possessor

The Harsh Possessor is the second Possessor boss Luigi faces in the Nintendo 3DS game Luigi's Mansion: Dark Moon. He is fought in the Tree House of Haunted Towers, where he has taken possession of a staircase. Major Parascope activity was coming from the top of the Haunted Towers and E. Gadd sent Luigi to go investigate the scene.

Appearance
While possessing the staircase, the Harsh Possessor turns it into a giant mouth by turning the staircase inside-out. The wheels that allow the staircase to roll now forms a hinge that allows the mouth to open and shut. A blue flame burns on each of the steps of the staircase while a pair of lit torches forms its eyebrows and eyes. Its tongue is a red cord and is only shown after attempting to crush Luigi.

The Harsh Possessor's true form is that of a lean white ghost with two horns protruding from the front of his head. A fragment of the Dark Moon can be seen inside of him.

Battle
The main attack of the Harsh Possessor while he is inside the staircase is trying to lunge at Luigi. The staircase will attempt to attack Luigi multiple times before flying into the air and trying to crush Luigi from above. After the staircase has taken damage, it will start to throw two blue flames several times in a row. Its lunge attack also gets progressively faster.

While outside of the staircase, the Harsh Possessor can ram into Luigi twice in a row. After he finishes his second charge attack, he will be momentarily stunned and vulnerable to a Strobulb flash. If Luigi gets to the Possessor fast enough, he can stun the ghost before he has a chance to ram into him.

In order to defeat the Harsh Possessor, Luigi must wait for the staircase to fly into the air and attempt to crush him. If the staircase misses, it will fall, become flat, and reveal its "tongue". Luigi must use his Poltergust 5000 to stretch the tongue and send it flying back into the staircase to make the Harsh Possessor fly out. After the Harsh Possessor shows his true self, Luigi will need to stun him with the Strobulb and proceed to vacuum off one of his skins. Repeating this process twice will defeat the boss.
