In a world where, until a few years ago, the streets were rocked by battles between colorfully clad men and women with astounding metanormal powers, the people have declared all-out war against these modern-day titans. Following the destruction of the city of San Francisco in a super-battle gone bad, the federal government has issued an executive order outlawing not only the use of super powers, but also the very people who possess them. For the beings known as Metanormals, it doesn't matter whether they were once superheroes, supervillains, or neither; if they commit crimes, save lives or just try to live normal lives without ever using their powers; they're all regarded as public enemies, and as such the legal prey of the murderous LAPD division G Platoon (presumably after SWAT's designation of D Platoon) known more familiarly as the Metanormal Tactical Unit, or "MTac."
