Mammon | Human in Hell series

Not much is known about Mammon's history other than that he joined Lucifer and the other Deadly Sins, embodying the sin of Greed and came to reside in the Greed Ring.

At the start of Hell, Mammon had met Asmodeus, who thought he sucks.

At an unknown point of time, Mammon had created the amusement park called Loo Loo Land, which is a shameless, poorly made ripoff of Lucifer's far more popular amusement park, Lu Lu World.

Mammon held a concert where he picked up a child and announced the start of his annual clown pageant. Then, he complained about taxes, assaulted the crowd with clowns, vomited and passed out on stage.

Ten years prior to "MAMMON'S MAGNIFICENT MUSICAL MID-SEASON SPECIAL (ft Fizzarolli)", Mammon began working with the recent winner of his annual clown pageant, Fizzarolli, where he had a line of robotic duplicates, toys and merchandise made in Fizzarolli's image.

At some point, Mammon realized Fizzarolli and Asmodeus were in a romantic relationship.

Mammon is a character in Helluva Boss whose iconography is first pictured throughout the episode "Loo Loo Land" and makes his official debut in "MAMMON'S MAGNIFICENT MUSICAL MID-SEASON SPECIAL (ft Fizzarolli)".

He is one of the Seven Deadly Sins, embodying the sin of Greed, and an influential business tycoon in the Greed Ring. He is also the owner of the theme park Loo Loo Land and the former boss of Fizzarolli.

Mammon is a rotund, four-armed demon who resembles a jester. He has neon green eyes with what appears to be an eye mask, and sharp neon green teeth with a tongue that's forked and purple with at least three dark yellow stripes inside his mouth.

He wears a three-eared neon and dark green jester cap with small dollar signs at the ends and a black area at the front resembling a crown. He wears a jester's collar colored half-dark green and half-neon green with yellow trim at the bottom and has black diamonds.

Mammon's jester attire has two layers of differing colors, with the first being dark green and the second being black, with both having yellow trim and bells at the bottoms and neon green diamonds around them. The sleeves fit into his gloves and are asymmetric, one on each side being dark green and black while the other has white and pale blue stripes.

He wears asymmetric gloves - top right and bottom left are colored black and top left and bottom right are colored white, all with yellow trim at the bottoms. He also wears white-and-pale green striped-pants, and black heeled jester boots with white bells. He carries a yellow cane topped with a large dollar sign.

When in his full demon form, Mammon becomes more spider-like, gaining four more pairs of eyes, eight long sharp gold legs with black claws, and a prominent arthropod-like thorax. His jester cap's ears also become sharper. He is shorter than Asmodeus, who in full demon form has to bend down to be at his eye level.

Befitting the sin he embodies, Mammon is very egotistical and greedy, and he doesn't care for the well-being of others, only caring about how much he can profit from them to indulge his own greed. However, he does appear to have standards as he was not pleased of taking loose change from a poor kid. Mammon acts friendly in front of his audience just to look the part and treats Fizzarolli like a son.

From what Fizzarolli has stated, Mammon is also a perfectionist. As his brand face, Mammon wants zero flaws in his brand figure whatsoever. He is also abusive, forcing Fizzarolli to do many stunts that put Fizzarolli in danger, such as being a living target for knife-throwing. However, Mammon also seems to show genuine concern over Fizzarolli when he starts having a panic attack, although it quickly changes to him looking threateningly and demanding for him to "get [his] shit together".

He has a foul mouth, even more so than most demons, even saying "c***" several times. He is also a chauvinist, publicly stating women "just ain't funny". Still, he claims to have reconsidered such comments upon seeing Glitz and Glam's performance and the twins becoming finalists.

There is also an ignorant side of him, such as when Fizzarolli is singing "2 Minutes Notice", he is unable to notice that the song is about him, even after Asmodeus says it is, and only realizes when Fizzarolli calls Mammon by name.

Mammon is also shown to be fairly confident in his own might, not being intimidated when Asmodeus, a fellow Sin, came to Fizzarolli's defense. Though he also shows he seemingly prefers not to fight directly, retreating when his threat to reveal Fizzarolli and Asmodeus' relationship fell flat, suggesting him to be somewhat cowardly despite his bloated ego. He is also known to be lazy as Asmodeus stated that he had not performed anymore clown acts and Blitzo called the last show he attended being an overhyped commercial.

As mentioned by Asmodeus in "MAMMON'S MAGNIFICENT MUSICAL MID-SEASON SPECIAL (ft Fizzarolli)", Mammon has existed since at least the start of hell, meaning he is thousands of years old and presumably is unable to die of old age.

He can generate sparks of green electricity from his body and generate sparks of green lightning when he teleports.

He can generate green smoke from his mouth, and also when he teleports.

He is capable of teleporting from one area to another, which he does so with an explosion of green smoke and a charge of green lightning that turn into $ signs, with audible cash register sound effect. Though the sound effect is absent when he confronts Fizzarolli on his resignation, implying that the sound effects may be based on his mood or emotions.

Mammon was shown to be able to generate explosions when he teleports and caused Mammon Theatre to explode at the end of "MAMMON'S MAGNIFICENT MUSICAL MID-SEASON SPECIAL (ft Fizzarolli)".

During his entrance in a flashback, he is shown playing the guitar.

His overall fun and optimistic demeanor and behavior gathers the admiration of all his fans when he shows up, even drawing the attention of Fizzarolli.

In "Mastermind", he sings in choir with the other Sins, showing his singing abilities.
