Blade-Tooth

Tooth Blade is a Quirk possessed by Moonfish.

Description
Moonfish's Quirk allows him to enlarge and reshape his teeth into 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.

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.
