Hasn’t been a villain for ages man. In the early 2000’s he sold off his symbiote as his cancer progressed. He attempted suicide at one point and then went into character limbo till around Civil War where he was in his final days and being driven crazy thinking the symbiote was still talking to him. He was influenced to try and kill aunt May, but he couldn’t go through with it and said to Peter “don’t worry, I cut it out of me, I’m better” or something before throwing himself out a window, but Pete webs him.
We next see him still gaunt, bald and ailing, but he’s working at Martin Lee’s F.E.A.S.T. homeless shelter and soup kitchen. He, May and Martin are very close and Eddie’s there in his final days to give back to the world. While he was in his final days, Matt Murdock cleared him of all his past crimes, citing that he was influenced by the Venom symbiote. Wishing to give back before he died, he joined FEAST.
During a backup story it reveals that his cancer in in complete remission and it may be due to dubious means. He celebrates by tearfully telling May and Martin. It turns out that Martin li is mr. Negative, he unknowingly used his Darkforce abilities and caused the antibodies and symbiote remnants in Eddie to mutate.
When the Thunderbolts dispatched MacGargan to hunt Spidey, he was being led in a direction by the symbiote. He lands in FEAST and realizes that it’s Eddie the symbiote led him to, not, Spidey. He’s taunting the very human Brock, but suddenly Gargan’s hands start to burn and Brock gets coated in a substance and transforms into Anti-Venom.
During a fight, he sees Spidey save an old man and he finally wakes up and buries his hatred of Pete then and there. He pretty much sacrifices his future to help Spidey since, in the post Civil War world, Norman Osborn runs the SHIELD-like agency called H.A.M.M.E.R. he helps Spidey save the day, but is branded a fugitive. He goes on to help others and becomes friends with a young drug addict named Jemma. He crosses paths with the Punisher and is instrumental in saving people from a mutating spider-plague in Spider-Island.
Eddie sacrifices his powers entirely to help create a cure, is declared the official hero of Spider Island, but is left penniless afterwards as things wind down. He begins hunting former symbiote hosts before getting captured and forcefully bonded to the Toxin Symbiote and goes after Agent Venom (Flash Thompson.) The arc with Symbiote Hunter Brock was to lead to a global event called the Spawning, but sadly never got written before Venom was cancelled.
During Agent Venom’s book, he fights Toxin, but Brock appears to perish in fire. He returns in a later arc to battle Flash due to him feeling symbiotes are a poison and is begrudgingly working with Toxin. After Flash and Eddie team up to stop another threat he mentions that he’s proposing a deal similar to the one Spidey and Eddie made when Brock fled to live in San Francisco in peace. Eddie says that if Flash loses control, he’ll mercy kill him and the symbiote. Despite being rivals Eddie wasn’t a villain here.
In the current Carnage book: Sometime later the government hunts Brock down in Philadelphia, he had been setting up shop there after the confrontation with Flash as a vigilante. He’s forcefully made to join up with an Anti-Carnage task force, Carnage is basically getting imbued with Cthulu powers and it’s a rather interesting read. The final issue comes out tomorrow. In it he continues his depth and the quote I posted earlier is from the previous issue. He’s trying to be a better man and willing to do what needs to be done.
After the events of Carnage he’ll appear in the current Venom book.
Overall, in the last decade Eddie Brock went off to limbo and then was given some amazing character development that has felt mostly natural and he’s greatly benefited from it. I do not want him to be a villain anymore and I hope that Costa (Venom’s current writer) weaves a compelling narrative for the big guy. He’s gone through a ton of interesting stories, so simply making him bad again would be a waste.
(I’m a huge Venom fan if you can’t guess lol)
Yeah, that always was a threat till his symbiote made him actually do that in Venom: The Hunger. Brock was absolutely traumatized and they split off once the symbiote went mad. It turns out that dopamine or phenylethylamine is needed by the symbiote, but Brock could calm it down by giving it chocolate once in a while. I remember afterwards there was a panel in a book where Venom was singing “the Venom Man” song to the beat of the 60s Spider-man while hoarding a bag of chocolate bars. hah
