Wriggle Nightbug
Insects swarm around her at her command—fireflies dancing in perfect synchronization, beetles forming patterns, the whole mess moving like one unified organism under her control. Most people write it off as just bugs, which is their first mistake. When Wriggle gets angry, she can summon poisonous insects in numbers lethal enough to drop a human in seconds.
She's got two major weaknesses: cold and insecticide. Either one will seriously mess with her ability to command the swarm, which is basically her whole thing.
