Acidman

Acidman (アシッドマン) is a Ultimate Move used by Mina Ashido using her Acid Quirk.

Description
After increasing the viscosity of her Quirk, Mina generates a large amount of acid that takes a vaguely anthropomorphic form that covers her entire body. This technique has defensive properties since every attack against Mina will be dissolved by the powerful acid that protects her.

Mina mentioned that she was inspired by Eijiro Kirishima's Red Riot Unbreakable to create this Ultimate Move.
