The Overset Possessor is the third Possessor boss of Luigi's Mansion: Dark Moon. It takes control of the clock face atop the Old Clockworks. The Possessor first appears when Luigi makes his way to the Belfry as he is told by Professor Elvin Gadd. After he scares Luigi, the Possessor proceeds to possess the clock face.
Profile[]
The Overset Possessor is a tall, white ghost with three horns. The fourth Dark Moon piece is located within him.
Battle[]
Luigi's Mansion Dark Moon - Old Clockworks - Showtime Boss Fight (Nintendo 3DS Walkthrough)

Luigi encountering a wave of Greenies during the gauntlet
The battle with Overset Possessor is quite unique in design. The battle takes place on a giant clock. Starting from 1 and ending on 12, the Possessor turns the clock ahead one hour at a time, summoning new enemies each time. Every time Luigi clears an "hour", the minute hand will catch fire and swing around, then extinguish. On the 4, 8, and 12 o'clock positions, the Overset Possessor will fight instead. After 8 o'clock, instead of the minute hand's flames going out, the hour hand will catch on fire, and it will remain like that for the rest of the battle. In order, the enemies fought are:
Time | Enemies |
---|---|
1:00 | One Greenie |
2:00 | Three Greenies |
3:00 | Five Greenies |
4:00 | Two Slammers: then Overset Possessor attacks |
5:00 | Ten beetles |
6:00 | Three Sneakers |
7:00 | Three Greenies with shields and hammers |
8:00 | Three Mummies: then Overset Possessor attacks again |
9:00 | Beetles |
10:00 | Five Creepers |
11:00 | Eleven Robombs |
12:00 | A mummy, a Sneaker, a Greenie with a shovel, a Slammer, Robombs, and a beetle: then Overset Possessor finally attacks again |

Luigi capturing the Overset Possessor a final time
When he is exposed, the Possessor will form a shield and charge around the arena four times. After the fourth charge, he'll be left stunned and Luigi can capture him. After the last hit, Luigi can obtain the fourth Dark Moon piece, granting him access to the Secret Mine.
Description[]
- "To protect the Dark Moon piece within him, he possessed the huge clock face at the top of the tower and called on hordes of ghosts to help him out. A battle to remember!"
