Number 6/Synopsis

History
At some point in the past, the person who was known as Number 6 watched as O'Clock's career fell apart and his face was seriously injured, leaving a scar that runs diagonally across his face.

As a sign of respect for him, Number 6 had self-inflicted on his face a scar similar to O'Clock's wound, becoming known as Number 6.

First orders
The first time Number 6 is seen in action was after Kuin Hachisuka's defeat. After Knuckleduster defeated her and removed the Queen Bee that controlled the host's body, he destroyed the Queen Bee and all her swarm. However, one of the bees survives and escape. Shortly after, Number 6, disguised as a cop, notices the last of Kuin's bees shakily flying through the air past him. In a flash, he jumps up and catches the bee in a plastic capsule, before leaving the place.

After this,Number 6 is in charge of illegal importation of Trigger to Japan, for its subsequent distribution, through the so-called "Crab Route". The Police, lead by Naomasa, carries out an operation to dismantle the distribution of the drug and arrest those responsible. The clues lead them to the SS Mall in Super Minami in the city of Osaka. There, the drug is distributed through the country hidden in Kanidoge's food packaged. For this operation, they have an infiltrated agent, Monika Kaniyashiki, as a worker in the Kanidoge chain; and Fat Gum in case of needing a Hero for the operation.

Monika goes to the SS Mall loading dock and she discovers that Trigger was indeed hidden in the packaged. She also discovers the criminal responsible for that, disguised as a part-time worker. Having been discovered, Number 6 congratulates Monika and uses his Quirk to snatch her gun and a tablet with vital information. Monika quickly takes cover and requests for reinforcements, so Naomasa, Fat Gum and the rest of the police forces come to the place to catch the suspect.

Despite being surrounded, Number 6 is calm and confident, and before anyone can stop it, he introduces a code on the tablet that causes the Kanidoge's mechs employed by the workers are out of control and go on a rampage. Thanks to Fat Gum and Monika, the workers are rescued and the mechs are neutralized. While the villain congratulates them for their actions, detective Naomasa gives him a warning shot, assuring him that next time he won’t miss. Monika warns Naomasa to be careful, as the villain has an acceleration quirk that gives him extreme speed. Taking into account this information, Naomasa orders the speedster villain to get on the ground slowly. The villain just smiles. Without noticing, the damaged mechs approach the batch containing Trigger and explode, destroying all evidence. The villain takes advantage of the distraction to flee with the remaining pieces of evidence using his quirk.

The police chase Number 6. As he‘s not giving up even after verbal commands and warning shots, Naomasa orders to open fire against him. Number 6 uses his speed Quirk and dodges all the shots, but the detective shoots once more, injuring him in the leg, after deducing that the villain’s Acceleration Quirk needs a few seconds of cool down time after using it. The police rush on to the injured criminal.

Confronted by the police, the Villain uses his quirk and the time seems to freeze. He gets away from the cops. His wound does not seem very serious since he was just got grazed by Naomasa's shot. The speedster villain checks that they use rubber bullets, and in a blink of an eye, he disarms a whole group of cops and shoots into their bulletproof vests with their own weapons. Although this does not kill them, it does leave all the policemen very badly wounded. The villain being able to finally escape with the remaining pieces of evidence without any problem.

Several days later, in an unknown apartment, Number 6 is training his Acceleration Quirk hard, to bring it to its limits. From an earpiece, the Villain Factory Employer tells him that his training is unnecessary, that he only needs to use firearms as he did in Osaka, but Number 6 replies that he is more partial to punching power. The voice tells him to do what he wants, that at least they get data about his physical state while accelerated. The call ends, and the speedster villain talks to himself that he only uses firearms when he is gets backed into a corner because guns are unheroic, as he contemplates a large O'Clock poster.

After this, Number 6 continues to carry out the works commissioned by the Villain Factory, such as releasing the Next-Level Villains through the streets of Naruhata to collect data and obtain samples, as he did with Octoid. After a tough fight against Koichi, Aizawa, the Hotta Brother and Kamachi, Octoid is forced to escape, fleeing into an alley, being pursued by the others. However, Number 6 finds him first and defeats him easily, obtaining a sample of his body. When he was about to leave, Octoid throw a stone at the speedster villain, causing him a slight scratch on his face, but that greatly angers Number 6, which almost kills Octoid from a beating before leaving.

Number 6 is also in charge of looking for people with powerful Quirks for the Villain Factory. To do this, he distributes a new variant of Trigger that is administered orally. It is less effective than the old form but lacks the psychotropic element. As this new drug does not turn people into full-blown villains, it makes it easier to distribute on the street, and therefore, it benefits the Villain Factory, because it makes easier for them to showcase potential candidates to kidnap and transform into Next-Level Villains. The police manage to catch and interrogate one of the distributors, and the investigation led the police to the place where the deals were happening, but Number 6 had already cleared out.

Plan to assassinate Captain Celebrity
Recently, Number 6 has set himself the goal of kill Captain Celebrity. To achieve this, he decides to take a test attack with a special Next-Level Villain: the Bomber. After the Captain celebrated Christmas at Marukane's department store with the Marukane Performers, Number 6 sends the bomber to hijack the taxi where the Little Sisters of Saint Lila’s Academy are. Captain Celebrity goes out in pursuit, but just when he is going to reach them, Number 6 causes the creature to explode with a device.

Using the aerodynamic barrier of his Quirk, Captain Celebrity manages to protect the girls, leaving unharmed of the explosion, although when doing it he lowers his own protection, suffering several wounds, although nothing really serious. The witnesses come to Captain Celebrity to congratulate him for what he had just done. Meanwhile,Number 6 observes everything on top of a building. With his attack, he manages to deduce the weak point of Captain Celebrity’s Quirk and decides to leave the place to prepare a new attack to end his life, releasing more flying bombers.

After the incident, Captain Celebrity announces that he will return to the United States of America. And for this, his friends decide to organize a big farewell party at the Tokyo Sky Egg in several weeks, where some of the most famous heroes of Japan will participate and that thousands of people will attend. And it will be at that moment when Scarred Man carries out his plan to assassinate Captain Celebrity.

However, Naomasa and the police are still on his trail; and thanks to an arduous investigation and a series of informants who give them important data, they manage to find what turns out to be the laboratory where the Villain Factory transforms the people who they kidnap into Next-Level Villains. The same day on which the Celebrity Farewell Party is celebrated, the Police Force, along with the heroes Eraser Head and Fat Gum, prepare to raid Onomura Pharmaceuticals Kanto R&D Center. When Naomasa gives the order, the police and heroes raid the place, arresting as many suspicious persons and seizing all possible evidence of illegal experiments. They hardly have any problems at first, thanks to Eraser Head and Fat Gum, who defeat the main threats, but when they arrive at the secret laboratory, they meet one of the Bombers.

When the creature prepared to self-destruct, Eraser Head cancels his Quirk with his Erasure, and Fat Gum launches on him to neutralize it. However, they discover to their horror that behind the first Bomber there are several more, too many for Aizawa to cancel the Quirks of all of them. And behind the creatures, is Scarred Man, who presses a device generating a huge explosion in the laboratory. Scarred Man manages to escape the explosion by grabbing the leg of one of the five surviving Bombers. The Villain admits to himself that, although he expected the authorities to end up discovering the place, he was not expected to do it so soon. Despite this setback, he decides to continue with his plan to kill Captain Celebrity, heading with the Bombers to the Tokyo Sky Egg.

Upon reaching the area near the Sky Egg, Scarred Man starts up his plan: one of the bombers sticks to the glass and explodes. This makes Koichi, who was near the place of the explosion, almost falls to the ground, while Captain Celebrity, after making sure that Koichi is well, goes out to face the creatures.

One of the Bombers explodes, hardly affecting him, but everything turns out to be a distraction, as an especially large Bomber clings to the tower of the Tokyo Sky Egg and explodes, seriously damaging the infrastructure, threatening to collapse with thousands of innocent people inside. To prevent the tower from falling, Captain Celebrity uses his enormous strength to hold the building, but this leaves him helpless.

Everything is coming out just as Scarred Man had planned, and sends one of the two remaining Bombers to attack him. It is a creature that was specially designed to face Captain Celebrity, with six arms, the ability to throw explosive punches and to regenerate any lost limb. The creature mercilessly attacks Captain Celebrity, but despite the punishment he received, he continues to hold the building, ensuring that he can withstand hundreds of those more attacks.

In the Tokyo Sky Egg dome, both the heroes and the audience are wondering about the many tremors rocking the dome. Some try to use their communication devices to contact the outside or other departments to know what is happening, but the remaining Bombers generates an EMP blast, causing a blackout in the building and cutting the cell signals. In the distance, Number 6 is satisfied with the result, because it prevents anyone from helping Captain Celebrity. With this situation, Best Jeanist takes the lead and deduces with more or less the intentions of the person responsible for what happened, so he devised a plan so those heroes capable of flight will exit and make contact with the outside.

Meanwhile, Captain Celebrity continues to hold the damaged structure so that it does not fall, while resisting the Bomber's attacks. When the creature prepares to attack him again, Koichi Haimawari appears and uses his Quirk to shoot the repulsion force blasts at the Bomber and blowing up his fists. Koichi's plan is to endure as long as possible protecting Captain Celebrity until someone can help them. The plan works. Koichi manages to stay long enough until the first heroes begin to arrive to assist them in their battle against the Bombers.

In the distance, Number 6 sees the Pro Heroes managing defeats his creatures while securing the building. He gets very angry when he sees how his plans are being dismantled by the heroes and decides to carry out his last move to kill the greatest number of people, in revenge for their interference. The Bomber that was attacking Captain Celebrity clings to the supporting tower. Number 6 uses his device to cause the creature to self-destruct in an explosion so powerful that the Tokyo Sky Egg begins to fall down.
