After being paralyzed from the waist down from a gunshot wound she sustained using her metamutant shadow powers to fight crime, Karen Chord attempted to fix her injury with her own inventions. Making an mechanical exoskeleton for her legs, designing crutches that could fire electrical "stingers", and equipping herself with artificial wings to allow her to fly, Karen resumed fighting crime as the Shadow Bee.
Shadow Bee is a metamutant with a link to the Darkshade dimension, and uses its power to transport herself and others through portals of dark energy. She can also become a living shadow and pass through solid objects.
Her winged exoskeleton allows her to fly and her crutches can fire electrical shocks.
