Mosquito Girl

Much of her frame is hardened exoskeleton, light enough to carry her aloft on wings. Each limb tapers into paired hooks, her lower legs bend backward in a digitigrade stance, and she sports an extra set of forelegs. Bristles cover her upper arms and shins, banded like a hornet, while a segmented abdomen trails from the base of her spine. Above a human face sit compound eyes, twin pairs of antennae, and a stubby proboscis, all crowned by shoulder-length white hair. Her curvy, full-chested build is at first entirely bare, leaving her insectile traits on open display.

When she transforms, the bands across her body sharpen into jagged patterns and her bristles and headpiece harden into spines. Following her defeat, Dr. Genus replaces her lost arms and legs with mechanical ones, and her wings and antennae shrink; while serving at the House of Takoyaki, she ties on an apron stamped with the shop's octopus crest.

Despite her human traits, she views people and animals purely as meals and is forever thirsty for blood. Her mosquitoes, by contrast, she dotes on like a mother, calling them her little ones and folding them into her attacks. Danger rarely rattles her; she stays haughty and only faintly annoyed, trading insults with her foes as readily as blows. Since her loss to Saitama she has softened into a friendlier presence at the takoyaki shop, though remarks about her strange looks still set her off, and going without blood sours her mood in a hurry.

In the Introduction Saga she descends on Z-City at the head of a mosquito swarm, driving residents indoors as the insects scour the countryside. After draining a stray looter, she is confronted by Genos, whose heat blasts vaporize scores of her insects; she severs his right arm but loses both lower legs to him in the same instant. Calling down a massive cloud of insects, she gluts herself on their blood, regrowing her limbs and emerging faster and stronger than before. The swarm then swamps Genos, who detonates them all; Saitama, drawn outside by a lone mosquito, is caught in the blast yet walks away with only his clothes destroyed. Her upgraded form carves Genos in two with ease, but a single offhand slap from the naked Saitama ends her.

She survives, as it turns out, since only her blood sack was destroyed. By the Neo Heroes Saga she is waiting tables at the House of Takoyaki, her insect limbs swapped for robotic ones, biding time while Dr. Genus regrows her blood sack and Armored Gorilla force-feeds her through a giant syringe. As a Demon-level being she wields immense strength and speed, matching an S-Class hero in combat, and her defining gift is command over every mosquito for dozens of kilometers, which she can summon to converge or to drain a target to a husk. Feeding on their blood triggers her metamorphosis, unlocking rapid regeneration and shockwaves strong enough to level a building, while a retractable frontal horn lets her stab clean through steel.
