The Supervillain Acts are a series of laws passed by the United States Congress over four decades that are meant to be a deterrent to black capes. Persons who are deemed to be black capes are always given the maximum sentence with no chance for parole or early release, which they serve in dangerous super-security prisons, such as Earbox. They are automatically and categorically denied the insanity plea. For each criminal count, a prosecutor may append an additional SV charge, which effectively doubles their sentence.

The acts have come under fire as unconstitutional by a number of civil rights groups.
