Carnage (Marvel)

Cletus Cassidy was already a dangerous serial killer before he became the powerful psychopathic super-villain known as Carnage.

While sharing a jail cell with Eddie Brock, the symbiotic alien that made Brock into the super-powered Venom, came and busted its former host out of prison. Some of the alien's spawn remained behind, and bonded with Cassidy, seeping into his bloodstream and creating a menace more powerful than Venom. As Carnage, he wreaked havoc across the city, and sought to destroy both Venom and Spider-man- the symbiote's previous hosts. Carnage easily defeated both of his hated foes individually, forcing Venom and Spider-man to team-up against him. Together they defeated him, but Carnage was always around after to cause them -and everyone else- misery. Carnage was at one point somewhat romantically involved with another insane super-serial killer, Shriek.

Carnage's powers include super-human strength, agility, and durability, as well as the ability to nullify Spider-man's "spider-sense". Carnage's skin is made of a web-like substance, and he can create weapons, tendrils, and other objects by sprouting parts of the symbiote from his body. He can even detach his weapon-tendrils and hurl them at opponents. He is virtually bullet-proof, as the symbiote can deflect bullets and other projectiles. His weaknesses are extreme heat, and loud vibrations, such as sound-waves.
