Serleena

"Oh yummy, someone I need to eat."

- Serleena

Serleena was the main antagonist in Men In Black II, although taking the form of an attractive human lingerie model once arriving on Earth she was in reality a shape-shifting alien resembling in many ways a monstrous plant-like creature of considerable size and power: she is arguably more powerful than Edgar the Bug, the antagonist of the first film and sought a mysterious power-source known as "The Light of Zartha" in an attempt to conquer the Planet Zartha and its people in the name of Kylothians, the same alien race whom not only she is from, but also their Queen and the ruler of their home planet Kyloth.

Serleena was aided by a duo known as Scrad and Charlie - who acted as her henchmen and the secondary antagonists of the movie.
