Venom character jug produced in China for Backstage Pass of the United States circa 2015. 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 Venom symbiote's first human host was Spider-Man himself, who eventually discovered its true nefarious nature and separated himself from the creature. The symbiote went on to merge with other hosts, beginning with Eddie Brock, its second and best-known host, with whom it first became Venom. Venom has endured as one of Spiderman's most prominent villains, and was initially regarded as one of his three archenemies, alongside the Green Goblin and Doctor Octopus.
