She is the product of a genetic scientist who set out to create a powerful weapon that he could auction off. Her mother was a Japanese teenager, and her father was an Andorian Eel. There are also about a dozen other species that went into her genetics giving her some interesting abilities. Except for her coloring she looks just like her mother. She gets her temper from her father.
She was raised by the slavers that kidnapped her at a young age, and had always remembered it as them rescuing her. With a taste of freedom she realizes that she doesn't want to go back to her old life, and joins her fate to the beast girl that dragged her from the slavers when she escaped their cage. Buried within her blood is a forgotten magic.
