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.

Years prior to the series during his concert, Mammon had skinny arms and a visible neck, and overall he appeared shorter. His eye mask had thick neon green borders and shiny black lenses, giving the appearance of shades.

He wore a three-eared blue and light blue jester cap with green ball at the ends, a black dollar sign at the front, and two additional ears on the left from the back. He wears a jester's light blue-green collar with a gap at the front where a coin sits in the middle and white trim at the bottom.

Mammon's jester attire had two layers of differing colors, with the first being pale blue, the second having pale blue and light blue vertical stripes, and both having white trim at the bottoms. The sleeves are loose and asymmetric, with the ones on the right being singular colors of pale blue and light blue. At the same time, the left side has both pale blue and light blue, with jagged lines separating the colors. Each sleeve has white trim at the ends.

He wears asymmetric gloves with two colors, black and two colored white. He also wears black-and-yellow-striped pants, and jester-like white platform boots with dark purple soles. He also had a yellow guitar with jester cap-like ears at the top.

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. Although 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*nt" 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.

Longevity - As mentioned by Asmodeus in "Oops", 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.
Demon transformation - Mammon can transform into a more powerful demonic arachnid form with a larger size and multiple eyes and legs.
Electrokinesis - He can generate sparks of green electricity from his body and generate sparks of green lightning when he teleports.
Typhokinesis - He can generate green smoke from his mouth, and also when he teleports.

Teleporting
Teleportation - 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.
Fragokinesis - 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)".

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