Gluttony Ghosts

 (often nicknamed as The Stomach Ghosts, The Belly Ghosts and The Gut Ghosts) are not only possessor ghosts, but energy ghosts (spirits born out of energy of humans) that are born out of the hunger, obesity and gluttony of humans.

Biography
Possessor energy ghosts that are born out of the hunger, obesity and gluttony of humans. They have made up a type of ghostly energy called "hunger energy", which makes them stronger and powerful. When humans eat enough food, it makes them and their energy stronger and powerful, building up a specteal battery inside.

They manifest in the form of spirits that resemble beer gut-like stomachs with visible belly buttons. They have wispy tails on the top of their body and doesn't even have limbs. Despite having lack of faces, they can speak. Like the Bulging Door Ghosts, they can bulge through solids.

When they possess people, they can bulge through their stomach as they glow a ghostly color, turn them into overweight ghosts, make them float in the air and bulge through doors and walls. What weakens the ghost is exorcising the humans they possess out of their bodies. They also repeatedly leave ectoplasm all over when they phase through solids.

They have built up a ghostly battery into the possessing victim's body inside. The glow inside the stomach represents the battery inside. When the battery is charging up, their belly glows more as it inflates. When the battery is full, it still glows as the belly stays inflated. When the battery is drained, the glow inside their belly fades away as the latter deflates.

Ghosts are shown to have different personalities.
