Carnage (real name: Cletus Kasady) is a fictional character and a major antagonist in the Spider-Man franchise and one of Spider-Man's most dangerous enemies. Cletus Kasady was already a dangerous serial killer before the symbiote made him the powerful psychopathic super-villain known as Carnage. Carnage is an arch-enemy to Spider-Man and also to Venom including Eddie Brock and Flash Thompson, and wishes to destroy both of them so he can cause mass-murder without end. He is also one of the, if not the, darkest, most insane and most disturbing villians Spider-Man ever faced.
