Mamon

Mammon is one of the Seven Deadly Sins, embodying the sin of greed.
Appearance: A plump, four-armed demon resembling a jester. He has green eyes, green teeth, and a blue tongue. Mammon wears a green and dark green jester's cap with three bells and small dollar signs on the ends.
Personality: Mammon is very conceited and greedy, not caring about the well-being of other demons, only how much he can earn from them. However, in public, Mammon is friendly.
In his full demonic form, Mammon takes on the appearance of a spider: he gains four extra pairs of eyes, eight long, sharp legs, and a pointed ribcage. Fizzarolli was Mammon's favorite character and the face of his brand. Mammon extracted every possible benefit from Fizzarolli: selling souvenirs and dolls featuring him, exploiting him, and even creating robotic replicas.
Mammon considered Fizzarolli something of an adopted son. When Fizzarolli was feeling ill, Mammon would give him a break to recuperate, but only so he could perform perfectly.
