Mammon is a spider-like demon with a distinctive Australian accent who is the Sin of Greed and ruler over the Greed Ring. Along with owning several businesses that make and/or are associated with money such as Loo Loo Land and banks, his very likeness can be found printed on Hell's currency. He's also the demon who made Fizzarolli a star when the latter won a contest to became the face of his clown brand, a thing that Mammon exploits Fizz heavily for the Sin's own profit.
