These beings merge with hosts, and the combined entity tends to have a personality based on both the symbiote and the host itself, though sometimes one side or the other tends to dominate. Venom's origins can be traced to a race of symbiotes from the planet Klyntar. No matter how hard anyone tries to keep the symbiote down, Venom always manages to come back, like a plague.
However, it is never clear how long Venom's darker impulses can be held in check. This combination has proven nearly lethal to the wall-crawler numerous times.ĭespite his hatred of Spider-Man, Venom has a twisted sense of morality, avoiding harming anyone he deems to be innocent and even performing heroic deeds. A hulking and twisted distortion of Spider-Man, Venom is the result of an alien symbiote merged with a human holding a bitter grudge against Peter Parker.
