Bye-Bites

A long jaw crowded with sharp teeth fronts what is otherwise a shark shaped like a man, fin included. Light blue skin, yellow eyes and dark blue hair round out the look. For the raid he wore a sleeveless jumpsuit fitted with a diving mask, an air cylinder strapped across his back.

He goes at defenseless U.A. students with no hesitation and no regret, despite having no quarrel with any of them, and would rather be done with them as fast as possible. Caution tempers the cruelty only slightly, since not knowing what their Quirks could do was enough to give him pause.

With the raid underway inside the U.S.J., he made for the Flood Zone alongside the others whose Quirks favored water. He waited there until Kurogiri dropped Izuku Midoriya into it, then came at him at full speed, only for Tsuyu Asui to intercept and haul Izuku and Minoru Mineta up onto the ship. The villains ringed the vessel, but none would board it, held back by not knowing what the students could do, which bought Izuku time to think of a way out.

Dozaemon then struck the ship, and the plan became to wait for it to sink and take the students in the water. Izuku moved first, driving a Delaware Smash into the surface to open a whirlpool that dragged the villains in. Minoru followed with a barrage of sticky spheres from Pop Off, cementing everyone in the water into one helpless mass, while Tsuyu carried Izuku and Minoru clear on her Frog Quirk. Bye-Bites went to prison with every other villain hired for the job.

His unnamed Quirk gives him a shark's physical traits, high swimming speed and a punishing bite among them, but apparently no gills, since he needs the diving cylinder to keep from drowning. His Japanese name reads as a play on sayonara, and the game My Hero Academia: The Strongest Hero simply calls him Shark Man.
