Venom is a fictional character appearing in American comic books published by Marvel Comics. He is a symbiotic life form that requires a host to survive and is most commonly associated with Spider-Man. The original Venom symbiote was an alien costume worn by Spider-Man, but after the web-slinger rejected it, the symbiote bonded with journalist Eddie Brock. As Venom, Brock and the symbiote combined their hatred for Spider-Man to become one of the web-slinger’s most dangerous foes. Over time, other characters have taken up the mantle of Venom, but Eddie Brock remains the most famous and enduring host of the symbiote.
