Mosquito Girl is a prototype artificial mutant created by Dr. Genus of the House of Evolution. Being partly insect, Mosquito Girl's body is largely exoskeleton. All her limbs end in twin hooks. Mosquito Girl playfully regards humans and animals as prey. In contrast, she treated her mosquitoes well, referring to them as "little ones".  Even in the face of danger, she is arrogant and only mildly irritated, insulting her opponents as much as assaulting them. She's considered a Demon Level Threat.
