"The scummy second-born who is greedy for all the money in the world. The witches are his big weakness."
— Mammon's Student ID

Mammon is a demon whose first appearance in Obey Me!'s Main Story was the game's first phone call in Lesson 1-1. His first appearance in Nightbringer's Main Story was also Lesson 1-1. He has six brothers, and as the second-most powerful of the seven, he holds the title of "second-born." He also possesses the title "Avatar of Greed" and is a representative of that sin. As one of the main characters in both Obey Me! and Nightbringer, he is included in both games' Intimacy system.

Appearance[edit]

Mammon has short, shaggy white hair, and sienna-colored skin. His eyes are a gradient of cobalt blue and yellow, and his nails are painted white. He typically wears gold stud earrings, as well as two rings on both the ring and pinky fingers of his right hand. In many card artworks from Obey Me!, the rings Mammon wears are the same color, sometimes being silver as shown in You Always Ride Shotgun or Fired-Up Fashion Battle!; however, they are also sometimes drawn as being both gold, such as in We Still Got a Ways to Go or I've Got Your Back, which matches his sprite, as shown in cards like Somersaultin'!.

Most often though, Mammon is drawn with the ring on his ring finger being gold and the ring on his pinky finger being silver, examples being shown in cards like Fashion Hot Shot or Best Seat in the House. His rings being different colors is most consistent in his Nightbringer cards, such as The Avatar of Greed or Troublemaker.

Mammon and Satan are the only brothers whose final design was not changed after their original concept arts.

As seen in the official height chart, Mammon is the second-shortest of the seven brothers, and nearly the exact same height as Asmodeus.

RAD Uniform

Mammon's RAD Uniform is the most unkempt of the seven brothers. He wears the typical charcoal grey jacket with gold accents, and matching charcoal-colored pants with red stripes along the sides. However, the jacket — which is shorter in length than the standard uniform — has all of the buttons left undone, and both zippers on the sleeves have been left open. His standard red-bordered belt hangs unbelted at his sides.

The teal shirt he wears beneath the jacket also has the first few buttons left undone, there are visible wrinkles throughout, and his saffron yellow tie hangs loosely tied from his neck. His leather shoes are the standard charcoal grey.

Mammon's School Uniform is an available outfit in Majolish. In Obey Me!, it is unlocked by default. In Nightbringer, it can be obtained by unlocking the Devil's Tree "Clothing" space in the Demon Card The Avatar of Greed.

Demon Look

Mammon's demon look was first revealed in Lesson 8-8 of Obey Me!'s Main Story, and is his standard appearance in Nightbringer. In this form, Mammon has a pair of small, black horns that protrude upward from his head. The horns have a tight, spiraling pattern before ending pointing upward above his head. His hair is also shown to have yellow tips in his card art, for example The Guardian Demon or The Avatar of Greed, although this is not reflected in his sprite.

Mammon also has a pair of bat-like wings on his back below his shoulders. The "arms" and "fingers" of the wings are white with yellow tips, and the "fingers" of each wing end with sharp-looking spikes. The wing membranes are a dark, charcoal grey.

When in his demon form, Mammon has thin, white markings that stripe across his chest and his back.

Mammon's outfit when in demon form consists of a studded, black bolero jacket with white, elongated diamond patterns on each of the sleeves, a high standing collar, and belts that criss-cross in front of his chest before connecting to his pants. The pants a black with a pattern of large, white diamond shapes along the left leg. He also wears a pair of charcoal grey, knee-high boots, each decorated with two sets of three gold, spiked studs.

The outfit consists of a white tank top with a dark grey trim, over the top of which he wears a bulky, hooded dark grey jacket with white and dandelion yellow accents. The jacket's lining is dark cerulean blue, not quite matching the royal blue belt around his waist. He also wears a second, dandelion yellow belt wrapped around the jacket itself.

His pants are dark grey with bright yellow lines down the inseams, and a white, geometric pattern on the left leg. The pants have attached white and gold suspenders left hanging loose at Mammon's sides. A decorative gold chain with a triangle pendant hangs from the left side of his waist, which matches the gold triangle pendant necklace around his neck. Said necklace was picked out for him by Beelzebub and Belphegor, as mentioned in Issue 6 of the RAD Newspaper. Mammon's high-top sneakers match the colors of his jacket and pants, in that they are black, dandelion yellow, and white.

Personality[edit]

Mammon's title "Avatar of Greed" is well-earned, and of the seven brothers, he is arguably one of the most constantly influenced by his sin. He is always looking to make more money or to spend more money, and this single-minded focus doesn't leave him much room to worry about the consequences. A D.D.D. app called "Demon Brain Scan" was used in Beelzebub's Devilgram Unspoken Affection to show that 90% of Mammon's brain is taken up by "money."

His brothers are often unwillingly dragged into his schemes and left to pay the price alongside him, as in the Pop Quizzes Summer Festival and Welcome to the Bunny Show. Mammon also often steals from his brothers, or borrows money from them with no intention of paying it back. Leviathan especially is a sibling he borrows from often, as seen in the very first lesson of Obey Me!'s Main Story, which led to Mammon being bribed by both Leviathan and MC into becoming MC's first pact. Making a pact with MC was a decision he made impulsively, which is something he very often does.^(source?)

Mammon's greed also can make him desire things not for their own sake, but because he knows other people desire them. In addition to borrowing from Leviathan and not giving the money back, Leviathan explained to MC in Lesson 1-15 (OM) that some time ago, Mammon won a Seraphina figure that he refused to let Leviathan have, not because Mammon himself wanted it, but because he knew his brother did.

Mammon being an impulsive, greedy troublemaker is largely the reason why his brothers often don't treat him kindly. In Belphegor's Devilgram, Hatred, Beelzebub commented that all of Mammon's brothers look down on him. His brothers also frequently insult him, calling him "scumbag" or "idiot" most often. Mammon is always very vocal in denying those insults. He desperately cares what other people think about him, even people he doesn't know. In Lesson 1 (OM), when Lucifer gave him the task of watching over MC during their stay in the Devildom, he did his best to ensure MC understood that he didn't agree to the task because he was scared of Lucifer. He also insisted in the chat Horror Movie Night that he wasn't afraid while watching a horror movie, despite it being obvious he was. He also becomes ecstatically happy whenever he's given praises, as seen virtually any time that MC chooses to compliment him.

Mammon often refers to himself as "Ore-sama" and "Mammon-sama." "-sama" is a Japanese honorific meant for those of higher rank, and "ore" is an informal pronoun for "me" or "I." Thus, "ore-sama" roughly translates to "The Great Me."

Despite his insecurities and the way his brothers often treat him, Mammon cares deeply for all of his siblings. He often plays the role of mediator between Lucifer and his younger siblings when they argue or are in trouble, as he did for Belphegor in the Devilgram Paying Back What's Owed. When not personally involved in the family feuds, he often does his best to talk both parties down, or come up with a plan to get his brothers back on better terms. It was Mammon's idea in Lesson 10 (OM) to use Leviathan's Dogi✩Maji✩Memorium game to give Lucifer and Satan a common goal to work toward, and thus help them get along better.

However, as level-headed as Mammon is capable of being, there have been times when he lost his temper and transformed into his demon form. One example occurred in the Devilgram Let Your Hair Down, when he, Lucifer, and Leviathan walk in on the younger brothers (sans Belphegor) bad-mouthing the eldest three. Another example is in the Devilgram Levi Dreams of Sleep, when Mammon learns that Leviathan spent the night with MC. A third example occurred in the chat Part-Timer Mammon 2, where Mammon was fired from his job after getting into a brawl with a customer, which resulted in a café being destroyed.

Mammon is often getting in trouble with Lucifer over his poor grades at RAD.^(source?) His worst subject at RAD is hexes and curses, as he admits in Lesson 29-2 (OM).

Powers and Abilities[edit]

Note: this section may include spoilers.

Mammon is the second most powerful demon brother and the Avatar of Greed. As such, Mammon has special powers involving money. When Satan introduced Mammon in Lesson 1 (OM), he mentioned that Mammon governs and oversees all forms of greed. He also explained that when Mammon takes a liking to someone, that person will find themselves awash in money, but if he decides to break it off with that person, Mammon also has the ability to leave them penniless. In Lesson 2 (OM), it is mentioned that if money is involved in games (i.e. gambling), Mammon will make sure it's his.

In Lesson 35-6 (NB), Belphegor brought up that Mammon's greed powers grant "amazing luck" to any human that has a pact with him.

Mammon is shown to have great control over his demon powers. Unlike the rest of the characters, Mammon rarely transforms into his demon form to be threatening.^(source?)

He also has crow familiars, and is able to communicate with them. This was first mentioned in the lesson chat Reporting In - obtained from Lesson 32-16 Hard (OM) - and brought up again in Lesson 75 Hard (OM). Mammon also used this ability to send a crow to check on MC in the Daily Chat To Mt. Imminent Death 7.

Mammon is also known to be one of the fastest demons, and he has more stamina than other demons. This is mentioned in several Devilgrams, such as Test of Endurance and Beach Flag Race!. Mammon's stamina is also shown in Lucifer's 2022 birthday event, when the brothers all ran out of the House of Lamentation to meet with Lucifer. When they arrived, they are all out of breath except for Mammon and Beelzebub.

He has also been shown to be physically strong. For example, in the chat Mammon's Training 1, Mammon was able to pick up Beelzebub, who is known to be extremely heavy.

Story[edit]

Background[edit]

Note: this section may include spoilers.

Mammon was originally an archangel that was under Michael's tutelage. However, as mentioned by Asmodeus in Lesson 44-7 (OM), Michael couldn't handle his mischievous and rebellious nature. It the same Lesson, it was made clear that his personality as an angel was much like his later demon self, including his proclivity for greed. Stunts like trying to sell a bunch of pigeon feathers from the Human World by claiming they come off of Raphael caused his brothers to worry he was on the verge of being cast out of the Celestial Realm.^(source?)

He was eventually turned over to Lucifer, who managed to straighten him out, and Mammon's been loyal to him since.^(source?) He was eventually promoted to the rank of Throne and became Lucifer's assistant, as seen in Lesson 44-7 (OM). He also used to watch over the younger angels such as Beelzebub, Belphegor, and Lilith, who always gave him a run-around.^(source?)

He rallied with Lucifer and his brothers in the Great Celestial War, but when they lost and fell into the Devildom, they became demons.^(source?) It was during this time that he served as a strong support for Lucifer as they all tried to adjust to living in the Devildom.^(source?) He also had a hand in "raising" Satan when he was born, but not much is known to how much he contributed.^(source?)

In Lesson 11 (OM), Mammon claims to be well over 5,000 years old.

Mammon sometimes works as a model, at least once for the fashion magazine "Devil Style" published by Majolish. One of his photoshoots was titled "Falling for You."^(source?)

Mammon stated that he sleeps in the nude in the chat Going Commando. However, in his Christmas Tree animation, he's seen wearing a white sleeveless shirt and gray sweatpants.

Obey Me!'s Main Story[edit]

Note: this section may include spoilers.

This section needs more info!

Lessons 1-10[edit]

Lesson 1[edit]

For reasons not specified, Mammon did not appear during the student council meeting when MC first arrived in the Devildom. He was instead called on his D.D.D. by MC, who told him that he was assigned by Lucifer to look after them during their stay in the Devildom. He initially refused, but after Lucifer threatened him, he changed his tune, though he claimed he didn't agree just because he was afraid of Lucifer.

After leaving RAD, he guided MC through the House of Lamentation, and they ran into an upset Leviathan, who insisted that Mammon hand over the money he owed him. Mammon pleaded with Leviathan to give him more time. One way or another, Mammon escaped the situation before Leviathan could further hound him.

Lesson 2[edit]

After successfully obtaining Mammon's credit card from the kitchen's fridge, Mammon happened upon Leviathan and MC defrosting the card in the microwave. He yelled at them to stop microwaving the card, then begged for "Goldie" — his treasured credit card's nickname — to be returned to him. Leviathan had planned for this, and stated that Mammon would only get his credit card back if he made a pact with MC. At first, Mammon refused, but when threatened with Lucifer's name, he hastily agreed to Leviathan's terms, and officially made a pact with MC.

After finding out about the incident later, his brothers teased and Mammon over breakfast and called him a "sorry excuse for a demon."

Lesson 3[edit]

That morning at breakfast, Mammon complained about the fact that he wasn't allowed to eat MC. MC then asked Mammon what was at the top of the attic stairs, and Mammon replied that they were sticking their nose where it didn't belong. He refused to tell MC any more about the stairs, until he was accused of being scared of Lucifer.

Finally, he cracked, and informed MC of how to distract Lucifer, which required a vinyl edition of the TSL Soundtrack that was in Leviathan's possession. MC made use of their pact to get Mammon to help them, and they went straight to Leviathan's room to ask him to lend them the soundtrack. Once there, Leviathan denied them entry, and refused to do them any favors. However, Solomon showed up and used a secret phrase to be granted entry to Leviathan's room. When Mammon and MC tried to repeat the same secret phrase, they were still denied access. Mammon concluded that since Solomon was allowed in for being a The Tale of the Seven Lords nerd, the solution was for MC to become a "TSL" nerd themselves.

Mammon was forced to join MC for the 12-hour TSL DVD marathon, and Beelzebub also joined them for the food. Mammon ended up getting surprisingly attached to TSL and its characters, even sobbing at dramatic plot points. The day after, Mammon was quizzing MC on their TSL knowledge when Leviathan then showed up. He claimed that he heard from Lucifer that MC was trying to suck up to him by becoming a TSL nerd. MC then challenged Leviathan to see who the bigger TSL fan was, and Leviathan eventually agreed.

Later, after MC disclosed Satan and Beelzebub's advice on making Leviathan jealous, Mammon boasted that they helped MC because of him being involved. He agreed that MC needed to find some way to make his brother jealous, and accompanied them to find someone to help with that.

The TSL showdown later commenced, and after three questions each, both MC and Leviathan were tied on points.

Lesson 4[edit]

After MC pulled their trump card during the TSL quiz, Leviathan flew into an envious rage and charged at MC. Mammon tried to save them, but slipped up, and was not able to get there in time. Instead, Lucifer saved MC. Mammon was extremely frustrated that he wasn't the one to save MC. While tending to their sprained wrist later, he stated that next time MC's life was in danger, he should be their only choice in terms of saving them.

Later at RAD, When Simeon and Luke interrupted an argument between Mammon and Beelzebub to invite them to a camping trip, Mammon expressed that a trip like that sounded "like a drag." He also used the time to pick on Luke by calling him "chihuahua" and "Fido."

Lesson 5[edit]

Mammon texted MC in the middle of the night that he was hungry, and asked them to come down to the kitchen. Once there, Mammon talked MC into eating Beelzebub's custard, despite having a note that read "Property of Beelzebub. Eat it, you die." Beelzebub then entered the kitchen and thought Mammon ate his custard, which caused him to transform into his demon form and attack Mammon. This resulted in severe damage to the kitchen wall shared by MC's room. The two brothers and MC are given a lecture from Lucifer, who then stated that MC would stay in Beelzebub's room until theirs was repaired. A jealous Mammon tried to argue against this, but Lucifer was unswayed.

Later, MC eavesdropped on Lucifer and Beelzebub's discussion about Belphegor, and Beelzebub insisting that Lucifer should forgive their brother. Mammon also was eavesdropping and led MC away to explain things to them. He stated that the brothers were once angels that resided in the Celestial Realm before they fell from grace. Back then, Lucifer was especially fond of Beelzebub, Belphegor, and Lilith, but after he pledged his loyalty to Diavolo, Lucifer followed his desires no matter what the cost.

At breakfast, Mammon showed concern for MC when they didn't eat much, and worried that they might be feeling sick. He was then shocked when Beelzebub also didn't eat as much as usual. He, Satan, and Asmodeus questioned why the Avatar of Gluttony wasn't cleaning his plate like normal, unaware that the leftover food was for Luke hiding in Beelzebub's room.

Lesson 6[edit]

After Luke went missing, Mammon called MC to get them and Beelzebub to come down to the underground tomb. When the two showed up, Mammon was attempting to calm down Lucifer in his demon form and poised to attack Luke, who was holding the grimoire kept down there. Mammon tried to get MC to move when they shielded both Beelzebub and Luke from Lucifer, telling them that Lucifer will kill them. Thankfully Diavolo arrived to prevent this.

The next day at RAD, Diavolo announced that there was going to be a retreat held at the Demon Lord's Castle. While discussing said retreat, Mammon declared that the castle was secretly a horrible place. He claimed that Barbatos had secret torture room and that there was a huge underground labyrinth with a monster.

Lesson 7[edit]

On the day the retreat began, Mammon changed his tune from before, and seemed very excited about the trip. After Lucifer rushed them off to the Demon Lord's Castle, Mammon earned himself some minor punishment from Lucifer, both after he commented on his eagerness to beat the others to the castle, and for jealously complaining that he wasn't assigned a room with MC.

After taking their belongings to their assigned rooms, everyone met back in the main hall, where Mammon let slip that he and Solomon had nefarious plans for their time at the castle. Lucifer overheard him and told Mammon that he expected him to come to his room later. During the castle tour, a talking painting of Helene — an ex-lover of Asmodeus's — pulled Mammon, MC, and several of the brothers into the painting. The painting operated as a kind of teleportation device, as everyone pulled inside landed in an underground labyrinth, where Leviathan's old pet snake, Henry 1.0 now lived. The snake didn't recognize Leviathan and tried to attack the group, which prompted them to run away. Solomon then used his pact with Asmodeus to make the demon strong enough to tame Henry 1.0. Once Henry 1.0 was fully enchanted by Asmodeus, he helped them find the labyrinth's exit.

Lesson 8[edit]

After dinner in the Demon Lord's Castle, Mammon, Satan, and Solomon snuck around the castle in search of treasure. However, Beelzebub's stomach growling scared them away, as they assumed the sound was a beast protecting the treasure. Sometime later, Mammon attempted to start a pillow fight in MC's room but was caught by Lucifer, who had received word of an attempted break-in to the castle vault, which he correctly assumed was Mammon. Mammon was then dragged off to Lucifer's room for a lecture with Diavolo.

The next morning, a sleepy Mammon didn't get much sleep the night before, as Lucifer lectured him well into the night. He attempted to stop Leviathan from posting about the incident online, while others started guessing what happened to him. After the scavenger hunt was explained, Mammon attempted to put himself in a group with MC again, but Diavolo stated everyone should stick to their room-assigned groups.

After the scavenger hunt, when Asmodeus stormed off due to Mammon having called him out for photobombing the photos of other teams, Mammon was enjoying the Celestial Realm food made by Luke for dinner. He also teased the angel by calling him "Fido" once again.

Once dinner was finished, the dance portion of the night began. Now in his demon form, Mammon was the first to approach MC to ask for a dance. He tried to explain himself by saying he was only asking MC because he didn't think anyone else would, but Leviathan and Satan called out his attempt for what it was. His request was in vain regardless, and MC ended up dancing with Lucifer instead.

Later that night, Mammon, Leviathan, Beelzebub, and MC met in the halls of the castle to begin MC's plan of getting a picture of Lucifer sleeping. They entered the room they believed to be the one Lucifer and Diavolo were staying in, but instead found Cerberus waiting for them.

In their attempt to escape, they ended up dropping through an opening in the floor back into the underground labyrinth and were again pursued by Henry 1.0. Because MC temporarily had access to Solomon's magic, they summoned Asmodeus, who charmed Henry 1.0 again, and everyone safely escaped the labyrinth. This led to Lucifer lecturing them but also led to Asmodeus entering into a pact with MC.

Afterward, in the room MC shared with Asmodeus, Mammon barged in and started yelling at Asmodeus for being too close to MC. The commotion gathered more people into the room, then the argument became a pillow fight. Mammon ended up taking a flaming pillow to the face, courtesy of Lucifer after one of his thrown pillows accidentally hit Diavolo.

The next afternoon, everyone woke up late from their eventful night and enjoyed a brunch of Human World food prepared by MC, Solomon, and Barbatos. Mammon and the others learned, however, that Solomon's cooking was truly horrible.

Lesson 9[edit]

After the retreat at the Demon Lord's Castle, the brothers and MC had returned to the House of Lamentation. A discussion in the dining room turned to MC's new pact with Asmodeus. When Mammon learned that MC wanted to make pacts to earn Lucifer's respect, he asked why they would want that. Lucifer was also curious, but Satan suddenly declared he wanted to make a pact with MC. An argument between him and Lucifer followed while Mammon and the others observed.

After the argument, in MC's room, Mammon, Leviathan, Asmodeus, and Beelzebub learned that MC wanted to earn Lucifer's respect so they could help repair his relationship with Belphegor. The brothers then told MC the story of the Great Celestial War, and how Satan was born from Lucifer's wrath. The brothers felt that if Satan made a pact with MC only to spite Lucifer, it would have the opposite effect MC wished for.

Later, Lucifer held a meeting in MC's bedroom to lay down some ground rules with Satan for the time they spent in each other's bodies. Mammon and Asmodeus also attended and attempted to cause some trouble with Satan and Lucifer's body. Mammon was also present the following day when the swapped brothers ran into, and were quickly found out by Diavolo in the hallway of RAD.

Back at home later, Lucifer discovered, through a slip-up by Leviathan, that Mammon had been getting up to no good as he had been taking advantage of being stronger than Lucifer while he was in Satan's body. Lucifer bribed Beelzebub to fetch Mammon and string him up in the stairwell. Sometime later that night, MC heard him crying and went out to find him still strung up. In exchange for letting him down, they negotiated that Mammon would have to help them patch things up with Lucifer and Satan.

Lesson 10[edit]

Leviathan, Mammon, and MC came up with the idea to make Satan and Lucifer play a dating sim called Dogi✩Maji✩Memorium, with the hope that it would help them reconcile. They would be pulled into the game world, where they would be unable to leave until they win, which they predicted would force them to work together to do. Leviathan registered himself as "Leviachan" and Mammon as "StupidMammon". Leviathan then explained to the others what they had to do to win the game. He had made MC the heroine, meaning everyone had to compete to increase their intimacy score with MC and get them to accept a love confession.

Mammon was not happy to hear that MC had been made the heroine and pretended to be doing the others a favor by offering to be the only one attempting to romance MC. The very competitive brothers ignored his offer and they all proclaimed they would win.

During an in-game class, Mammon was caught by the teacher sleeping through the lesson, they woke him and asked him to answer a question. MC whispered to him the answer which Mammon thanked them for. As a result, MC could choose to declare that interaction as resulting in his intimacy score going up or down.

On the final day of the game, it turned into a monster survival game. After they defeated all the monsters, the final boss spawned on the rooftop, which turned out to be Cerberus. At first, Lucifer was not able to tame him, but after seeing Cerberus about to attack Satan, Lucifer was able to successfully tame him, after he hurled a string of censored threats at him, and the game ended.

Obey Me![edit]

At first, Mammon was annoyed with MC because he was forced to act as their guardian, even more so after they tricked him into a pact he only agreed to in order to get his credit card back from Leviathan.^(source?) However, after spending more time together with MC, Mammon's feelings quickly deepened for them, though often denies it if others point that out.^(source?)

He often has trouble expressing his feelings towards MC, and will become embarrassed or act like he doesn't care.^(source?) However, he often becomes jealous when someone else is taking up MC's attention or gets too close to them.^(source?) He also keeps reminding MC (and everyone else) that he's the first demon MC made a pact with.^(source?)

Mammon is often interested in anything that could deepen the relationship between him and MC, as seen in Lesson 43. In this lesson, he heard a rumor that the coffee at The Angel's Halo café will make your crush fall madly in love with that person when they drink it. A similar situation occurred in the Devilgram Lemon Parfait Lovers, where if two people shared a lemon parfait at Lament's Café, they deepen their relationship.

Belphegor[edit]

Obey Me![edit]

While Mammon is rarely treated with respect by his younger brothers, he is still quite protective of them, and this includes Belphegor. In the chat An Unexpected Approach 1, when Lucifer demanded to know who broke one of the paintings in the House of Lamentation, Mammon took the blame, much the surprise of the brothers. However, as revealed in the second part of the chat, it turned out that Belphegor had knocked against the painting while half-asleep, causing it to break.

In the Devilgram Paying Back What's Owed, Mammon also protected Belphegor from Lucifer when he skipped his classes at RAD to sleep all day, and asked him to ease up on his younger siblings, as it was shortly after their fall from the Celestial Realm.

When asked about Michael in Lesson 43-19, Mammon replied that he's "a demon masquerading as an angel." He apparently gave Mammon a number of terrible punishments when he was still an angel. Mammon also said that Michael was very similar to Lucifer in attitude.
