Supervillain
An example of a supervillain
A supervillain was a villain that was oftentimes the enemy of a superhero. They were often considered evil, and might have had superpowers, or at least was an evil genius, such as mad scientists or criminal masterminds like Professor Moriarty.
In 2380, Ensign Beckett Mariner asked Brad Boimler who he thought was the "baddest badass," and he told her he thought it was Roga Danar, since he was able to outsmart Picard and had great hair; but Mariner told him that no one had ever heard of him, and that Khan was really cool because he was a supervillain and a "space seed."
