A new player emerges in the underground world of villains in the form of the Meta Liberation Army. Led by the CEO of the Detnerat Corporation, the MLA is preparing for a new metahuman revolution.

It's army versus league in all-out war, and dominance must be established.

What would the world be like if 80 percent of the population manifested superpowers called "Quirks"? Heroes and villains would be battling it out everywhere!
