Acid

Acid is a Quirk used by Mina Ashido.

Information
Mina's Quirk allows her to shoot out corrosive liquid from inside of her body and can control the degree of solubility as well as its viscosity. Aside from her Acid attacks, she can also use it to make the ground slippery and slide across. Another advantage is the she can use her quirk to melt floors and walls, making her a good use for espionage.

The only downside to her quirk is that if she makes a single mistake her clothes may be dissolve as well.
