He is an alien that infiltrates host body and enhances capability to gain superhuman power. This character was introduced as villain in Spider-Man comic.

Venom joined again with his host and left his offspring unintended. Due to prison condition, Carnage was born after infected host, Clestus Kasady. He was cellmate when Eddie Brook in prison. That is why Carnage and Venom have similar characteristic. The only difference is the color; carnage uses red and venom is commonly in black. In Spider-man series, this villain kills many humans. Unfortunately, Carnage has more power because he does not have human-side aspect. He is purely evil without conscience of humanity. This situation gives Spider-Man hard time to kill and need to join force with Venom to completely annihilate him.
