The Carnage symbiote's codex still dwelled within its former hosts, and when Cletus consumed Scorn's codices it caused his then-current symbiote - an offshoot of the Grendel - to assume the appearance of the original Carnage symbiote, transforming him into Dark Carnage after Knull's death, the original symbiote's consciousness would reunite with Cletus' codex in piloting the Dark Carnage symbiote, resurrecting it in a new, more powerful form. It was eventually removed from Normie and left to be studied at Alchemax. Traces of the symbiote remained inside Cletus' body and rejuvenated in an attempt to save him from atmospheric re-entry, but perished in the process leaving the Goblin Childe's symbiote as the only known remaining offshoot. Spider-Man defeated Norman by tricking him into separating from the Carnage symbiote before immolating it. During his assault on his own family, he bonded an offshoot of the symbiote to his own grandson, Normie, turning him into the Goblin Childe. When it was eventually separated from him, Norman Osborn (also known as the super villain Green Goblin) took possession of the symbiote and became the Red Goblin. Dubbing himself Carnage, Cletus became a deadly recurring enemy to both Spider-Man and Venom.

The spawn bonded to Cletus through a wound in his hand, merging with his blood and becoming red-and-black in color. When the Venom symbiote came to rescue its host, Eddie Brock (who is also known as the super villain Venom), from jail, it left an asexually-produced offspring behind. The symbiote known as Carnage is the spawn of the Venom symbiote and is most often bonded to the sociopathic serial-killer Cletus Kasady.

As it is, I feel nothing but cold empty contempt. some of it would have crossed over to me.

a little more human love for his own daddy. Maybe if my host had a little more filial sentiment.
