Princess what's Her Name is the twin sister of The Evil Queen Pulsating, Bloated, Festering, Sweaty, Pus-filled, Malformed, Slug-for-a-Butt...however she shares very little in common with the Queen in both temperament and appearance.
Unfortunately for her, she is considered incredibly ugly by Insectican standards. Standards enforced by her sister at any rate...so has a very hard time in her home world. Of course being of Insectican blood makes her strong and quick enough to fight back.
Born in the dark underground catacombs of Insectica with her sister, she came out of her egg-sack blinking and smiling cutely - her sister grimacing and flashing her red eyes furiously. In all the history of the Insectican monarchy there had never been anything like her. She was exiled where no-one would know of her and hidden away in disgrace. No one even gave her a name.
Over time this served to make her determined. Realising it didn't have to be that way and that she had the strength to be free, she took her chance and escaped from the palace.
Owing to the immense amount of distress felt by the Queens followers after Earthworm Jim's victory over her and the damage to the royal catacombs, they were able to escape planet Insectica.
Not impressed by being hit on the head by a cow shortly after her rescue, she couldn't see how a giant Earthworm in a super suit, would be much help to her crusade of liberating Insectica from her despot sister. But she soon grew to enjoy his company and friendship over time.
