They often possess extraordinary powers, advanced technology, or exceptional intelligence, allowing them to execute elaborate plans for domination or destruction. Supervillains are commonly found in comic books, movies, and television shows, where they serve as the main antagonists. These characters often have distinct personalities and backstories that explain their motivations, such as a desire for revenge or a quest for power. Famous examples of supervillains include The Joker, Lex Luthor, and Thanos, each with unique traits that make them memorable and compelling adversaries to their heroic counterparts.
