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.

A deranged serial killer, Kasady bonded with the Carnage 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 separating from the symbiote following the events of Absolute Carnage, Kasady nonetheless continued calling himself Carnage, bonding with the Extrembiote symbiote as his new primary symbiote avatar.

Since his introduction in comics, the character has been adapted into several other forms of media, including television series and video games. Woody Harrelson portrayed Cletus Kasady in the live-action Sony's Spider-Man Universe (SSU) films Venom (2018) and Venom: Let There Be Carnage (2021), bonding with Carnage in the latter film. In 2009, Kasady was ranked as IGNs 90th Greatest Comic Book Villain of All Time.

Publication history Writer David Michelinie intended to have Venom's human alter ego, Eddie Brock, be killed off in The Amazing Spider-Man #400 and have the symbiote continue to bond with a series of hosts. 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 appeared 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 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 dead and was absent from comics for nearly six years. A 2010–2011 limited series titled Carnage featured the return of Kasady as Carnage. The comic was released as a tie-in to the "Big Time" storyline in The Amazing Spider-Man. This was followed by another five-issue limited series titled Carnage U.S.A. and published in 2011–2012. Carnage was next seen in the 2012 "Minimum Carnage" crossover storyline between Scarlet Spider vol. 2, Venom vol. 2, and two one-shots titled Minimum Carnage Alpha and Minimum Carnage Omega. The character crosses over with the Superior Spider-Man in the 2013 five-issue limited series called Superior Carnage, written by Kevin Shinick.

A new Carnage series, starting in November 2015, as part of Marvel's post-"Secret Wars" relaunch, was written by Gerry Conway and Mike Perkins.

Fictional character biography Early life Cletus Kasady is a psychopath and a homicidal sadist.
