Venom (Marvel)

Venom is a character from Marvel Comics. In most versions of Venom's story Spider-Man discovers a black substance that is used by him as a costume. When Spider-Man learns that the costume is actually a living symbiote that could not stand to be separated from its host for very long and can control the host, compelling him to violence, he tries to get rid of it. The symbiote survives and takes Eddie Brock as its new host, and as the two dislike Spider-Man for their own reasons, they became the malicious villain Venom to get revenge on him, and the two know that Spider-Man's secret identity is Peter Parker. Venom is stronger than Spider-Man, the symbiote can imitate the functions of his webs and it is undetectable to Spider-Man's Spider-Sense. However, the symbiote is vulnerable to heat and sound. Venom tried to kill Spider-Man, but Spider-Man managed to defeated them several times. After one of his defeats, Eddie Brock shared a cell with multiple-murderer Cletus Kasady, and when the symbiote appeared to free Brock and become Venom, the symbiote left behind its spawn, which bonded with Kasady and became the villain Carnage. Some time later, Venom made a truce with Spider-Man and became an anti-hero.
