Marvel’s current Venom comic has already dramatically rewritten the history of the symbiote, and now it’s doing the same for its host, Eddie Brock.
Warning: this article contains spoilers for Venom #11!
Much of Eddie Brock’s story over the past 15 years has been dominated by his battle with cancer. The 2003 Spectacular Spider-Man series first revealed Eddie’s cancer diagnosis, while also showing that the symbiote was drawn to Eddie specifically because it feeds on the adrenaline his sick body releases. Later, 2004’s Marvel Knights Spider-Man featured a storyline where the dying Eddie auctioned off the symbiote to the highest bidder. And even as other characters like Mac Gargan and Flash Thompson had their stints as Venom, Eddie himself found himself cured by Mister Negative and transformed into Anti-Venom.
