History
Homicidal maniac, Cletus Kasady was serving out his life sentence in prison when a new cellmate moved in, Eddie Brock aka Venom. In the midst of a jailbreak, the Venom symbiote spawned an offspring that bonded to Cletus, creating a symbiote that was stronger and deadlier than either Spider-Man or Venom. Known for cutting brutal and bloody swaths throughout the country he has more than earned the name: Carnage.[1]
