The Registration Acts — the Mutant Registration Act (MRA), the Superhuman Registration Act (SRA, or SHRA), and the Vigilante Registration Act (VRA) — are fictional legislative bills that have been plot points used in various comic books and superhero films which, when passed into law, enforce the regulation of vigilante vs. criminal activity and/or the mandatory registration of superpowered individuals with the government. The issue that the government might seek to regulate the activities and civil rights of super-heroes, or view them as valuable national security resource subject to conscription without notice in times of crisis, has also been explored in other comics, such as those featuring DC's Justice Society of America team, series like Watchmen, Astro City and Powers, the films The Return Of Captain Invincible (1983) and The Incredibles (2004), and in role-playing games Brave New World (1999), and Dawn of Legends for Savage Worlds.
