Mammon

Mammon is the ruler of the Greed Ring in Hell. His name is credited as the owner of the theme park Loo Loo Land. Not much is known about him besides the fact that he claims that he and Lucifer are friends, as shown in his contract regarding the issues for his theme park. He owns the character of Fizzarolli, and by extension his robotic duplicates. He appears to own a cereal brand called Greed Seeds, and a bank called Moneymakerz Bank, among other businesses.

Personality
While Mammon hasn't been directly shown yet, judging from the posters and writing signed by him, Mammon is very insistent on small details, such as stipulating in his contract that Loo Loo Land not being a bootleg duplicate of Lu Lu World by the case of its spelling.

Appearance
Mammon, based on his appearance in portraits of him throughout the many things he owns, has the appearance of a basic jester, somewhat resembling Fizzarolli. He wears a jester hat and collar and what appears to be an eye mask. In his depictions so far, he dons a large sharp-toothed grin.
