Number 6/Synopsis

History
At some point in the past, the person who will be known as The Scarred Man met Knuckleduster, when he was still the Pro Hero known as O'Clock. Because he has an acceleration Quirk similar to his own, O'Clock decided to adopt him as a disciple and train him. Much is unknown about what happened at this stage, but at some point, O'Clock lost his quirk and his face was seriously injured, ending his career as a hero. Many thought he was dead.

By his part, the disciple decided to become criminal, and at some point decided to work for the Factory. As a sign of respect for his former master, the disciple self-inflicted on his face a scar similar to his master's wound, becoming known as the Scarred Man.

Synopsis
The first time the Scarred Man is seen in action was after Kuin Hachisuka's defeat. After Knuckleduster defeated her and removed the queen bee that controlled him from the host's body, he destroyed the Queen Bee and all her swarm. However, one of the bees survives and escape. Shortly after, the Scarred Man, 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.
