Blade-Tooth (歯刃 (しじん) Shijin?) is a Quirk possessed by Moonfish.


Tooth Blade

Moonfish's teeth warped into razor-edged blades.

Moonfish's Quirk allows him to enlarge and reshape his teeth into keen and powerful blades.

He can control the size and direction of the blades at will. Manipulating his teeth allows Moonfish to attack from a distance and helps him maneuver through the air or certain terrains. He also often uses them to walk, leaving him hanging by his teeth.[1]

The blades are powerful enough to break through Shoto Todoroki's ice, but they aren't unbreakable. At full power, Dark Shadow was easily able to shatter Moonfish's teeth.[2]
