Iwao Oguro vs. Number 6

Knuckleduster vs. Number 6 is the combat between the Vigilante Knuckleduster and the Villain Factory member Number 6.

Prologue
Number 6 had attacked the Tokyo Sky Egg to assassinate Captain Celebrity using the Bombers, but the intervention of the heroes makes his plan fail. Therefore, the villain decides to take revenge, first causing the Tokyo Sky Egg to collapse, and then using a swarm of Minibombers to kill as many people as possible, but both attempts are prevented by All Might.

Number 6 is overwhelmed by the power unleashed by the hero number 1, being almost impossible to believe that someone with such power can exist. Suddenly a voice from his earpiece starts talking. the mysterious voice reassures him and told him that the goal of the Villain Factory is to create a being comparable to All Might. With nothing more else to do, Number 6 decides to withdraw. With all the Bombers wiped out and the laboratory destroyed, the only thing he can do is disappear for a while.

Unbeknownst to him, he is being observed by Knuckleduster through the scope of a sniper rifle, willing to shoot him to prevent him from escape. During the previous weeks, Knuckleduster had been analyzing and monitoring the activities of the Villain Factory, so he could deduce what their next move would be attack the Tokyo Sky Egg event, to use it as a testing ground. He looked for what would be the ideal rooftop to provide the best view of the Sky Egg in case he decided to observe the attack, and then search for the ideal spot to snipe the villain.

Battle
Knuckleduster is about to shoot the villain in the head, but unfortunately just at the moment he pulls the trigger, a bird passes in front of his scope, causing him to miss the shot, piercing speedter villain left shoulder. Despite failing, Knuckleduster thinks he still has a chance to shoot him again, but when he prepares to do so, Number 6 has already located his position, and using his Quirk, he jumps from one building to another despite his injure until he reaches the rooftop where Knuckleduster is, killing in the process the bird that involuntarily saved his life.

Despite the shot, Number 6 seems happy to meet Knuckleduster face to face, and greets him, but the vigilante only comments that, in addition to his acceleration Quirk, he has noticed that his body has been tinkered. The villain confirms his suspicions by saying he has pain resistance, muscle enhancement, and other modifications but he is still a work in progress, and his quirk is called Overclock, the same Quirk Knuckleduster once held when he was the hero O’Clock.

The Villain says that he always wanted to meet him, calling him master. For his part, Knuckleduster asks him who he is. He has been watching him for a while and he knows that he is the current holder of his former quirk, but except that, he have no more information about him, no name, no origins, etc ... the Villain replies that he is a nobody, a thing still unformed, and he has no real name, he is just called Number 6. However, he hopes to become O'Clock, because there’s no other name for him.

Number 6 tells him that he has always admired him. He has always considered him the best hero, even more than All Might, and asks Knuckleduster to recognize him as his successor, the heir of the name O'Clock, but Knuckleduster replies that’s impossible for two reasons: First, he already has a disciple (Koichi), and second, he does not intend to allow a villain scum like him, who is in possession of his stolen Quirk, to continue to exist.

Resigned to the fact that his idol rejects him, the speedter villain taunts Knuckleduster that he has lost his chance to kill him, and provoke him to shoot him again with the sniper rifle. Knuckleduster does it, but thanks to his acceleration, Number 6, he deflects the gun aside, causing Knuckleduster to miss the shot. The villain mocks him, saying that without his Quirk he is a nobody, and since he does not intend to recognize him as his successor, he intends to kill him to be the only O'Clock.

The villain increases the musculature of his arm and activates Overclock again, however he does not know that he has fallen into a Knuckleduster trap. With Overclock activated, he is distracted by a voice recording that Knuckleduster had prepared. In this recording, the Vigilante explains the characteristics of his former Quirk, and emphasizes on a fatal drawback of Overclock that the villain does not know: When Overclock is activated, if the user is intensely focused on something, he experiences "brain drain", depriving his brain of oxigen. The faster he goes, the bigger the brain drain, meaning he will run out the clock even faster than normal. For instance, when he is trying real hard to listen to a recording played back at 300 times normal speed, as he is doing right now.

The villain tries to back off after realizing his mistake, but Knuckleduster does not want to give him the chance to recover, and throwing his rifle aside, he quickly activates a detonator he has hidden in his trench coat, generating an explosion that destroys the rooftop and several several floors below. With nothing that allows him to maneuver in mid-air, Number 6 can only fall to the bottom, and yet KD doesn’t stop attacking him. Hanging on his grappling hook, he pulls a shotgun out under his trench coat and shoots to the villain legs, so he can not land properly.
