Carnage is a supervillain appearing in American comic books published by Marvel Comics, usually as an adversary of Spider-Man and the archenemy of Venom, in particular the Eddie Brock incarnation of the character, although Carnage and Venom have joined forces when their goals have aligned. The character made its first appearance in The Amazing Spider-Man #361, and was created by writer David Michelinie and artist Mark Bagley, although the first published artwork of Carnage was penciled by Chris Marrinan. Stan Lee would also have some input in the character's name and attributes, pushing for a character who would be far darker and vicious than Venom, due to the latter's more scrupulous character development.

Venom is a character appearing in American comic books published by Marvel Comics. The character is a sentient alien symbiote with an amorphous, liquid-like form, who survives by bonding with a host, usually human. This dual-life form receives enhanced powers and usually refers to itself as "Venom". The symbiote was originally introduced as a living alien costume in The Amazing Spider-Man #252, with a full first appearance as Venom in The Amazing Spider-Man #300.
