Queen Slug-For-A-Butt

The Queen Pulsating, Bloated, Festering, Sweaty, Pus-filled, Malformed, Slug-For-A-Butt is the main villain from the first Earthworm Jim game.

Story
The evil Queen Slug-For-A-Butt is the ruler of the planet Insectika. The planet, which was once beautiful, became a putrid wasteland under her rule, but she believes she did an excellent job in ruling the planet, so she decided she deserved to rule the entire universe. She has a twin sister, the Princess What's-Her-Name, whom she banished and imprisoned. She ordered one of her henchmen, the Professor Monkey-For-A-Head to create a spacesuit to her, so she would become even more powerful than she already is. The professor created the Ultra-high-tech-indestructible-super-space-cyber-suit, which was to be delivered to her by another of her lackeys, Psy-Crow. But an accident made him drop the Suit on Earth, where a worm entered it and mutated him, makig him become Earthworm Jim. Jim hears about the queen and her twin, deciding to rescue the princess. Jim then travels the universe after the Queen, facing Psy-Crow and the professor along the way, as well as many other villains. Jim eventually reach Buttville, a hive-like citadel where the Queen hides, facing the Queen and ultimately defeating her.

In the cartoon series, the Queen plays the same role from the games. Differently from the other villains of the series, she sees Jim only as a nuisance, but holding a serious grudge against the princess (who is considered ugly by the Insectikans).

Personality
The Queen is simply plain mean. She never smiles, and is always threatening others, even when she doesn't need to.
