The back story of Carnage and Venom is quite complex. Both originated from the symbiote species. Venom was the first to bond with a human host, and Carnage emerged as a more violent and unstable offshoot.
In the comics, the outcome of their battles varies. Sometimes Venom emerges victorious and kills Carnage, but there are also instances where Carnage escapes or the fight ends inconclusively.
Carnage is born when a part of the Venom symbiote finds its way to Cletus Kasady. The symbiote's influence and Kasady's already unstable nature merge to form this fearsome character. It's a combination that leads to chaos and destruction in the comic universe.
The 'Venom vs Carnage Graphic Novel' is a must - read for fans of the characters. Venom, originally a villain, has evolved into more of an anti - hero. Carnage, on the other hand, is pure evil. Their clashes in the graphic novel are filled with high - energy action. The narrative also explores the origin and nature of their symbiotic relationships, which is really interesting. It's a great piece of work that shows the complex relationship between these two powerful and menacing characters.
