Widow Vemon is a female exoskeletal mutant who was once a human scientist until she was exposed to genetic, radioactive fluid containing insect DNA. When she was exposed, she started to molt her human skin off and become Widow Vemon overnight. When she woke up, she saw that no one would understand, so she ran away to live a new life in the darkness. She is the girl friend of the Toxic Mutant, who is the only man who understands her as a person. She has the power to communicate with insects and other arthropods.
