Cletus Kasady became Carnage in Amazing Spider-Man #360. His original symbiote was destroyed in #363, but it was revealed in Spider-Man Unlimited (1st series) #1 that his altered metabolism could recreate the symbiote biomass and abilities from his bloodstream at will.

He was believed dead after Sentry tore him in half in New Avengers (1st series) #2, but survived thanks to his symbiote and was revealed to be alive in Carnage #3.
