Forget whatever you thought you knew about the history of Venom and his symbiote costume, because Marvel just debuted a radical new origin story for this ex-Spider-Man villain.
Warning: this article contains spoilers for Venom #4!
Previous stories have established that the Venom symbiote is a member of an alien race called the Klyntar. While the Klyntar as a whole are a peaceful race, the Venom symbiote was driven into a bloodthirsty rage during its time away from home until it was finally cured during Brian Michael Bendis’ Guardians of the Galaxy run. This issue doesn’t necessarily eliminate any of that backstory, but it does reveal that the story is much deeper and more complicated than fans ever realized.
