The Fat Gum Agency is the Hero Office belonging to the BMI Hero: Fat Gum. It is located in Esuha City, in the Kansai region of Japan.


Fat Gum Office

Fat Gum's office.

The Fat Gum Agency, is a large building with a rounded roof located between two others. The main facade of the building is decorated to mimics the appearance of Fat Gum himself. The upper part looks like the BMI Hero's face, with a black area representing his mask with two round windows simulating his eyes. Below this area there is a row of windows positioned so that reminds Fat Gum's distinctive smile.

The bottom of the facade has the initials of Fat Gum alias, with an F and an inverted F on the sides and a G surrounding the entrance door. The words "Fat Gum" are posted just between the initials as well. On the left side of the building there is a decorative element that represents Fat Gum's arm holding a takoyaki ball.

Inside, the office is austere, with a table, a huge dark chair and a few furniture.[1]


My Hero Academia Vigilantes

Fat Gum uses Fat Absortion Vigilantes

Fat Gum fights against the Mechs.

Fat Gum is contacted by Detective Naomasa to assist in a police operation to stop the illegal instruction and distribution of Trigger by the Villain Factory during a Mascot Idol festival at the SS Mall in Super Minami, Osaka.[2]

The infiltrated agent Monika manages to find out the drug and the main suspect, a villain known as Number 6. The villain activates a code that drives the mechs to start rampage the place.[3]. Although Fat Gum manages to avoid any casualties, in the attack the mechs destroy all the evidences, and the villain manages to escape after hurting numerous policemen.[4][5]

Onomura Pharma Corp Raid

Fat Gum participates in the Onomura Raid.

Weeks later, the police discovered the Villains Factory's base of operations, the Onomura Pharma Corp. Naomasa contacts Fat Gum to work with Eraser Head and Monika, first to investigate people connected to the company, [6] and later to participate in the police raid on the pharmaceutical company.

The assault force reaches the secret laboratories where the Factory conducts its experiments. There they meet again with Number 6, surrounded by creatures known as Bombers. Number 6 blows up the labs, fleeing with the Bombers to the Tokyo Sky Egg to kill Captain Celebrity.[7]. Fortunately, Fat Gum and the rest of the police operation survive the explosion[8], and the Number 6's attack fails thanks to the intervention of the heroes. [9]

Shie Hassaikai Arc

At some point, Fat Gum accepted Tamaki Amajiki to work at his agency. Although Tamaki proves to have great potential as a hero, his lack of spirit prevents him from standing out. Fat Gum tries to help him in this aspect. After a long time, following Mirio Togata's advice and with the help from Tamaki, Eijiro Kirishima ends up interning under Fat Gum as well.

Red Riot Unbreakable

Eijiro goes beyond his limits using Red Riot Unbreakable!

While patrolling the streets in Esuha Market, a group of criminals appear and Fat Gum stops them from running. When one of them escapes, Suneater turns his fingers into tentacles and stops him from fleeing. In a crowd of civilians, another thug takes out a gun, wanting to help his allies. Fat Gum notices the presence of the thug and yells at everyone to get down. The thug fires a special bullet, one that hits Suneater and another at Red Riot's hardened head. Red Riot, now angry, states he will capture the thug. He hardens his whole body and leaps into action.[10]

Suneater tries to use his Manifest again but for some reason he can not activate it, which surprises Fat Gum and questions if the thug has a Quirk eraser. Meanwhile, Red Riot chases the villain to a dead end. The villain uses his Quirk to create blades on his body but Eijiro knock the man down. In this situation, the villain injects himself with a Quirk booster, that allows him to generate unleashes a flurry of blades that consume the entire alleyway. To deal with him, Red Riot hardens his body even further, revealing his new super move: Red Riot Unbreakable.[11] Thanks to this, Red Riot breaks through his attacker's assault and defeats him. The villain tries to escape but Fat Gum intercepts him and traps the villain inside his stomach.

Then, while dialoguing with his interns, Fat Gum states that the villain used an inferior version of the Quirk booster drug he had encountered before. However, internally Fat Gum is worried, because it is the first time he knows the existence of a drug that cancels the quirk.[12]

Fat Gum points out Eijiro Kirishima and Tamaki Amajiki

Fat Gum talks about Tamaki and Eijiro.

A few days later, Fat Gum, Eijiro and Tamaki attend a Hero Team Up meeting in Nighteye Agency about the yakuza Shie Hassaikai, and his leader Kai Chisaki. There they are also Izuku, Ochaco, Tsuyu, Mirio and Nejire, Ryukyu - Ochaco, Tsuyu and Nejire's work-study mentor-, Shota Aizawa, Gran Torino, and many other heroes. Once they are all in the conference room, Sir Nighteye explains the situation and comments that thanks to the information some of them provided him with, he was able to make substantial progress with his investigation.[13]

At the meeting it is revealed that Shie Hassaikai has been behind several criminal activities, such as robbery and drug trafficking. They are also responsible for the production and circulation of Quirk-destroying bullets. However, the bullet used on Tamaki seems to be a prototype since it did not destroy his quirk, they tries to obtain the final version. Fat Gum reveals that, after recovering the bullet that bounced off Eijiro, they were able to examine the contents and found out that it contained human blood and human cells. Therefore the drug has a human origin, from someone capable of erasing Quirks.

Nighteye Hero Conference

Conference at Nighteye Agency.

Then Sir nighteye explains two important details: First, Kai Chisaki, the leader of the Shie Hassaikai, has a Quirk called Overhaul. Chisaki's Overhaul Quirk gives him the ability to disassemble or restore objects, an ability that can break down something and then reassemble it. Secondly, apparently Kai has a daughter named Eri, although there is no birth certificate of her and details about her are unknown; Izuku and Mirio encountered her on their patrol and she had a number of bandages on her. With this Sir Nighteye concludes that Kai Chisaki is probably using his daughter to make those Quirk destroying bullet, disassemble and reassemble her constantly to obtain the raw material. Fat Gum, like everyone else, is disgusted with Kai's crimes and demands that they hunt them down.

After explaining a few more details, Sir Nighteye concludes the meeting, and begins to organize the police and hero operation to dismantle Shie Hassaikai. Sir Nighteye states that their objective will be to save Chisaki's daughter.[14] [15]

Fat Gum and another hero investigating

Fat Gum spying on Shie Hassaikai associates.

For several days, Fatgum, along with several other heroes, investigate all properties connected to the Shie Hassaikai, trying to find the place where they hold Eri. Finally, they are informed Nighteye that they have found the girl. Once everyone is at the Nighteye Agency, Sir Nighteye reveals that Eri is being kept in the main hideout underground, and orders them to prepare to begin the rescue operation.[16]

The next morning at 8:00 AM, in front of the Police Station, Heroes partaking in the rescue operation have been given detailed information about the Shie Hassaikai's headquarters and its members. At this point in time, Fat Gum gives Tamaki a can of swordfish. Finally, at 8:30 AM, the Heroes and Police Force are outside the Shie Hassaikai's Headquarters and commence the operation.[17]

Shudder! The Underground Labyrinth

The Heroes charge into the hideout.

As they go through the operation, several comrades are left behind to face the threats, like Ryukyu's Team against Rikiya Katsukame. The group led by Sir Nighteye advances defeating all Yakuza who try to stop them. As the Heroes head down towards the basement but are surprised to see a wall before them.

Mirio Togata uses his Quirk to phase through the wall and tells the Heroes that the wall was thrown in the way to block them. Tamaki surmises that Chisaki is stalling them for time to hide everything and escape. Mirio decides to go on ahead and phases through. After Izuku and Kirishima knock down the wall, the floor starts to warp and open up beneath the Heroes due to Joi Irinaka's Mimicry Quirk, causing the heroes to fall down in a hall where three members of the Eight Bullets await for them: Toya Setsuno, Yu Hojo & Soramitsu Tabe.

Chimera Kraken

Tamaki facing the Eight Bullets.

As Fat Gum prepares for battle, Tamaki decides to battle the three Eight Bullets himself in order to make up for falling under pressure.[18] Tamaki restrains and disarms the three yakuza and tells the others that he can handle them. Fat Gum instructs everyone to get moving because Tamaki surpasses them all in terms of ability.

Despite his words, the battle against the three Yakuzas turns out to be very hard for Tamaki, suffering numerous wounds during the fight and being about to be killed, but in the end he manages to prevail and defeat them.[19][20] Tamaki restrains the villains and poisons them enough so they can't pose any more of a threat. He moves to regroup with the others, but he notices the great pain coming from his face and falls unconscious.

Making their way through the underground labyrinth, Fat Gum overhears Izuku and Eijiro discussing Tamaki. He tells the two that the mark of a true man is to have the ability to completely trust someone who has their back. Suddenly, Shota is attacked by a piece of manipulated wall, courtesy of Mimic, but Fat Gum shoves Shota out of the way, and is thrown into another room. As Fat Gum gets up, he is surprised to see that Eijiro is with him. Eijiro tells Fat Gum that he was also trying to protect Shota as well but once he did, he was swallowed by Fat Gum's Quirk.

Rappa breaks Red Riot Unbreakable

Kendo Rappa effortlessly breaks through Red Riot's defense.

Suddenly, two of the Eight Bullets, Kendo Rappa and Hekiji Tengai, appear. Eijiro activates his Red Riot Unbreakable, but Rappa’s rapid bullet-like punches are so powerful that manages to break through his defenses. Fat Gum counters with a punch of his own, but is surprised that his attack strikes a barrier instead, created by Hekiji. Despite this beginning, Fat Gum tells Eijiro not to give up and encourages him to keep fighting.[21]

The fight continues, and Rappa launches an assault on Fat Gum with his multiple fast punches, but Fat Gum withstands the attacks and taunts Rappa into a fight to determine who is stronger. Fat Gum absorbs the punches and takes in a lot of energy, which burns away his fat and making his defense weaker. Eijiro watches the fight in disgrace as he thinks he is unable to do anything. However, he is ashamed of his thoughts and appears in front of Rappa, blocking his punches.

Fat Gum defeats Rappa & Tengai

Fat Gum defeats Hekiji Tengai and Kendo Rappa.

Although Eijiro is defeated shortly, he gives Fat Gum the time needed to release his accumulated strength.[22] Thanks to Eijiro few seconds of bravery, Fat Gum has absorbed Rappa's accumulated blows which have in return given him great strength, and tells the yakuza that they are going to lose because they underestimated Eijiro. With his spare hand, he unleashes a powerful blast that smashes both villains. [23]

Despite his powerful blow, Kendo Rappa stands up but to Fat Gum surprise, he does not attack them, if fact he tells Fat Gum that there are first aid supplies in a nearby room and tells him to treat Eijiro's wounds while referring him to as a man. Fat Gum questions about it being a trap, but Rappa denies it, explaining he vows his interest in them both and wants fight them again, despite Fat Gum Fat warns him that he will be arrested.

Shie Hassaikai aid room

Kendo takes Fat Gum and Eijiro to the Aid Room.

Fat Gum moves Eijiro to the infirmary where he bandage him, stopping the bleeding. Then he asks Kendo what he was doing working for a gang. After hearing his explanation about Kai Chisaki, Fat Gum begins to become concerned and proceeds to ask Rappa about Chisaki's plans. Due to their injuries, neither Eijiro nor Fat Gum can continue participating in the rescue operation. [24]

Meanwhile, the raid continues. More and more members of Shie Hassaikai are being defeated by the remaining heroes. After being unconscious for several minutes, Tamaki wakes up when he feels that something bad happened to Mirio immediately after the latter gets shot with one of Overhaul's Quirk-Erasing Bullets.[25]

Tamaki goes out in search of others, encountering a wounded and unconscious Mirio and several police officers who accompany him. While carrying Mirio, he saves Shota's life when he was about to be stabbed by Hari. Tamaki manifests his hand into a swordfish and pierces Hari's arm with the bill, causing him to drop the sword. The Police Force who demand that Hari surrender. Tsuyu Asui appears from behind and asks Tamaki to come with her to the surface.

Once there, he discovers that Izuku has managed to defeat Overhaul and rescue Eri. With this victory, the members of Shie Hassaikai are arrested sending to prison. Fat Gum, Eijiro Kirishima, Tamaki Amajiki and other wounded heroes are sent to a hospital to be cured and recover.[26] Although they suffered serious injuries, none of the wounds is life-threatening and they recover over time.[27]
