Mantis

Mantis (カマキリ) is the Quirk of the Kirihito Kamachi.

Description
This quirk presumably grants the user mantis-based powers and abilities, judging by how Kirihito seemed to handle using his Quirk when under the effects of Trigger.

Usage
After being bio-engineered into a large humanoid mantis with very sharp claws; when boosted by Trigger this Quirk makes Kirihito much bigger and sharpens his claws.
