Batto Yobayakawa

Bat traits mark Batto long before anyone modifies him. His ears come to points, his teeth are sharp, his feet finish in claws, and large wings hang beneath arms noticeably darker than the rest of him. He is tall, and keeps his black hair shaved at the sides and swept back on top. For clothing he uses a sleeveless bodysuit, a belt fastened by a buckle at its center, and a smoked visor.

The Villain Factory's work pushes him further from human. Afterward his skin goes entirely dark, his ears enlarge, his hair crops short with a small patch sprouting across his back, and dark fur covers him from the waist down, leaving something closer to a bat crossed with a man. The visor stays.

Speed is what Batto is proud of and how he grades everybody else, so he mocks anyone he judges slow, writing Ingenium off as a turtle. He nurses grudges too. Being beaten by Koichi Haimawari is reason enough to come looking for him later.

For all the boasting, he studies his opponents closely. When Ingenium abruptly matches his pace, Batto works out that the hero has shed weight to manage it, and he is right: Ingenium had stripped the airbags out of his costume beforehand. He also recognized at once that Team Idaten had spread into a net around him, and went through it anyway.

Batto's Quirk, Bat, gives him wings on his arms, and Trigger turns that into a public problem. Dosed and loose, he tears down the Naruhata highways at least three separate times, each run ending the same way: he is simply gone somewhere in the district before anyone can corner him, and the inflammatory incidents pile up.

Team Idaten, the agency of Turbo Hero Ingenium, draws the job. Tensei Ida runs him down and tells him to stop, gets nowhere, and takes a kick that costs him control, though his costume's airbags spare him serious injury. Batto disappears again. That evening he reappears on a highway five kilometers out, and this time Tensei has a plan, funneling him toward a dead-end stretch with the rest of the team waiting to take him. Batto answers by manifesting his wings and flying out of the trap, which finally explains the vanishing act. He touches down in the older part of Higashi-Naruhata, gets past Team Two and everyone after them, and is midway through boasting about his speed in a back alley when Koichi Haimawari slides out and trips him. Knuckleduster knocks him cold, and the pair tie him up for Ingenium's team to collect.

The Villain Factory, the outfit pushing Trigger into Naruhata, sees potential in him. They manage to abduct him, experiment on him, and return him as a Next-Level Villain, faster than he was and carrying a sense of smell sharp enough to pick Koichi out of a crowd. Number 6 hauls him chained inside a delivery truck to an ad shoot where Tensei is filming with Captain Celebrity, then opens the roof remotely as the truck barrels in. The crash releases Batto onto the set. He goes straight for Tensei, anticipates the hero's attempt to hold him down and kicks him to the ground, then leaves to settle up with Koichi. Captain Celebrity gives chase and cannot close the gap, noting that Batto's rebuilt speed now rivals his own. Hearing Koichi singing at Narufest, Batto swoops onto the stage and carries him off in his claws, and only by slowing to grab him does he let Captain Celebrity catch up, knock him out, and save Koichi from the fall. Batto is arrested a second time.
