Supervillain groups are fictional collectives of villains that often band together to achieve their nefarious goals. These groups typically feature a variety of characters, each with unique powers or skills, allowing them to execute complex plans against heroes or society. Examples include The Legion of Doom from DC Comics and The Sinister Six from Marvel Comics. These groups often serve as antagonists in comic books, movies, and television shows, providing a formidable challenge for the protagonists. Their dynamics can include rivalries, alliances, and betrayals, adding depth to their stories and making them compelling adversaries for heroes like Batman and Spider-Man.
