Carnage is a fictional supervillain from the Spider-Man series and one of Spider-Man’s most dangerous enemies. He is a symbiote-born serial killer, most famously bonded with Cletus Kasady, which amplifies his violent impulses and gives him shapeshifting, superhuman strength, and lethal weapon-like tendrils. In the Spider-Man mythos, Carnage serves as a brutal, chaotic antagonist who represents pure mayhem and bloodlust. He is often portrayed as more savage and unpredictable than Venom, making him a major threat in comics, animation, and related adaptations.
