Originally believed to be an alien material, Spider-Man's black costume was more than that - it was an intelligent, symbiotic organism, and it could influence or even control whoever it bonded with. When Spider-Man rejected it, the symbiote's behavior changed, and its future hosts would provide a channel for its rage as the vigilante Venom. Bitter photographer Eddie Brock was the first Venom, and Brock's ex-wife Ann Weying also wore the symbiote as She-Venom. Currently it is attached to government operative Flash Thompson, with the symbiote replacing the legs he lost in combat.
