Carnage character jug produced in China for Backstage Pass of the United States circa 2015. 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. Carnage belongs to a race of amorphous parasitic extraterrestrial organisms known as Symbiotes, which form a symbiotic bond with their hosts and give them super-human abilities. Originating as an offspring of Venom, Carnage is much more powerful than its parent symbiote because of the symbiotes' biology and is in many ways a darker version of him. This version was created when Cletus Kasady bit Eddie Brock's hand and absorbed part of the Venom symbiote. After saving Kasady, Carnage forms an alliance with him to kill Brock and Venom. Due to their bond being incomplete however, Carnage and Kasady are defeated, with the former being eaten by Venom.
