Acidman

Acidman (アシッドマン) is an Ultimate Move performed by Mina Ashido using the 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 is able to use this move on others, showcased when she used this on Tenya Ida during Class 1-A's fight to bring Izuku Midoriya back to U.A.

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