Cletus Cortland Kasady is a supervillain appearing in American comic books published by Marvel Comics. Created by writer David Michelinie and artist Erik Larsen, the character first appeared in The Amazing Spider-Man #344 (March 1991) as the first and most infamous host of the Carnage symbiote, an offspring of Venom. Originally a deranged serial killer, Kasady bonded with the symbiote while sharing a cell with Venom's human host, Eddie Brock, and broke out of prison using the super-human abilities granted by it. Since then, he went on to menace both Venom and Spider-Man, resulting in various unlikely alliances between the two to defeat him. Kasady and Carnage are a perfect match, as they both have sadistic personalities, and the symbiote only increases Kasady's already existent violent tendencies. After being separated from the redeemed Carnage symbiote in Absolute Carnage, Cassidy nonetheless continued calling himself Carnage, bonding with Grendel, Mania and several other symbiotes to become Dark Carnage. Since his original introduction in comics, the character has been adapted into several other forms of media, such as television series and video games.

In 2009, the Cletus Kasady version of Carnage was ranked as IGN's 90th Greatest Comic Book Villain of All Time.

However, as Brock and Venom's popularity increased, Marvel would not allow him to be killed. Michelinie decided to create a new character: a total psychopath who, unlike Venom, had no sense of morality. The human component of Carnage's first host, Cletus Kasady, was designed by artist Erik Larsen, who modeled the character after the DC Comics supervillain the Joker. Kasady was introduced in The Amazing Spider-Man #344 and first appears as Carnage in issue #361. As the host of the Carnage symbiote, he is the main villain in the 1993 "Maximum Carnage" crossover, a 14-part storyline crossover that spanned through all the Spider-Man titles. In 1996, two one-shot comics centered entirely around Carnage were released, entitled Carnage: Mind Bomb and Carnage: It's a Wonderful Life, both of which expand on his character. After a 2004 appearance in New Avengers the character was presumed
