The concept of Venom began not as a villain, but as a new costume for Spider-Man. In 1982, a Marvel Comics reader named Randy Schueller submitted an idea for a new, all-black stealth costume for Spider-Man made of unstable molecules that would enhance his powers. Editor-in-chief Jim Shooter purchased the idea for $220 and, years later, the concept was integrated into the 1984-1985 crossover event, Secret Wars. In Secret Wars #8 (December 1984), written by Jim Shooter and drawn by Mike Zeck, Spider-Man acquires a black alien “costume” that responds to his thoughts and produces its own organic webbing. The idea to make the alien costume a sentient being that would later become a villain is credited to writer/artist John Byrne. The suit's nature as a parasitic entity that wanted to permanently bond with Peter Parker was explored throughout The Amazing Spider-Man and other titles. Peter eventually forcibly rejects the symbiote in a now-iconic scene in Web of Spider-Man #1 (April 1985), using the intense sonic vibrations of a church bell. Writer David Michelinie and artist Todd McFarlane are credited with the creation of Venom as a distinct character. Michelinie conceived of a villain who was a dark, more powerful version of Spider-Man, whose human component blamed Spider-Man for his ruined life. McFarlane designed the character's terrifying visual identity, with the massive physique, fanged maw, and long, prehensile tongue. After a cameo on the final page of The Amazing Spider-Man #299, Venom made his full, spectacular debut in The Amazing Spider-Man #300 (May 1988). The character was an instant sensation, tapping into the “grim and gritty” zeitgeist of late '80s and '90s comics, and quickly became one of Marvel's most popular and marketable characters.
The origin of Venom is one of the most significant points of divergence between the primary comic universe and its cinematic adaptations. Each narrative is built on a completely different foundation, leading to distinct character motivations and relationships.
The story of the Earth-616 Venom symbiote begins long before it ever met a human. It was a member of an extraterrestrial race called the Klyntar. The Klyntar are a naturally benevolent species who seek to bond with worthy hosts to create noble warriors, a process they view as a perfect symbiosis. However, if they bond with an unworthy or corrupt host, the symbiote itself can become corrupted, violent, and parasitic. The Venom symbiote was deemed insane by its people after bonding with a series of unworthy hosts, which filled it with rage and aggression. It was imprisoned and separated from the Klyntar hive-mind. This imprisoned symbiote was later discovered among many other alien technologies on the planet known as Battleworld by the cosmic entity, the Beyonder, for his “Secret Wars.” When Spider-Man's costume was damaged in battle, he was directed to a machine he believed would repair it. Instead, he released the imprisoned Klyntar. It instantly bonded with him, taking the form of the sleek black costume he had envisioned, one that could respond to his thoughts, change its appearance, and generate its own organic webbing. For months, Peter Parker reveled in his powerful new suit, unaware of its true nature. He found himself more aggressive and exhausted, discovering that the suit was taking his body “joyriding” while he slept. With the help of Reed Richards of the Fantastic Four, Peter learned the shocking truth: his costume was a living, parasitic alien that was attempting to permanently bond with him. Horrified, Peter used a sonic blaster to separate himself from the creature. The symbiote escaped, but its feelings of love and admiration for its ideal host, Peter, had curdled into a deep sense of betrayal and rejection. It eventually found its way to the Our Lady of Saints Church, drawn to the despair of a man named Eddie Brock. Brock was a promising journalist for the Daily Globe whose career was destroyed when he published an exposé identifying the serial killer Sin-Eater, only for Spider-Man to capture the real killer, revealing Brock's source to be a compulsive liar. Fired, disgraced, and filled with a suicidal hatred for Spider-Man, Brock prayed for deliverance in the same church where the symbiote was hiding. Sensing Brock's intense, focused hatred for their mutual enemy, the symbiote bonded with him. Their two minds, two sets of memories, and two burning hatreds merged into one. They were no longer just a symbiote and a man; they were a singular, vengeful being. They were Venom.
It is crucial to distinguish between two interconnected cinematic universes: the Marvel Cinematic Universe (MCU) produced by Marvel Studios, and Sony's Spider-Man Universe (SSU), which focuses on Spider-Man's supporting characters. The character of Venom, as portrayed by Tom Hardy, is a central figure of the SSU. In this continuity, the Venom symbiote's origin is completely divorced from Spider-Man. It is one of several symbiotes discovered on a comet by a probe from the bio-engineering corporation, the Life Foundation. Brought back to Earth for study by CEO Carlton Drake, the symbiotes are shown to be unable to survive long without a host, and Drake begins illicitly experimenting with human bonding. The Venom symbiote escapes captivity by bonding with an astronaut and hopping between several short-term hosts before finding its way to Eddie Brock. This version of Eddie is an investigative journalist who loses his job and fiancée after aggressively confronting Drake about his unethical practices. While infiltrating the Life Foundation to expose Drake, Eddie is accidentally exposed to and bonded with the symbiote. Unlike the comic origin, this bond is not born of shared hatred. It's a relationship of necessity and mutual survival. The symbiote, calling itself Venom, communicates directly with Eddie, and their dynamic is portrayed as a dark, often comedic, “buddy-cop” relationship. Venom explains that on his world, he is something of a “loser,” much like Eddie. Together, they work to stop Carlton Drake, who has bonded with another, more powerful symbiote named Riot. Their goal is to prevent Drake/Riot from bringing more symbiotes to Earth to consume humanity. This version of Venom has no pre-existing knowledge of or animosity towards Spider-Man. Its connection to the MCU was established in the post-credits scene of Venom: Let There Be Carnage, where a multiversal event (caused by Doctor Strange's spell in Spider-Man: No Way Home) transports Eddie and Venom into the MCU. They briefly learn about the MCU's Peter Parker before being sent back to their home universe, but a small piece of the Venom symbiote is left behind, leaving the door open for a future MCU-native Venom with a potentially different origin.
The powers and nature of the Venom symbiote are largely consistent across its main incarnations, but the host and circumstances drastically alter how they are used, as well as the composite being's personality.
The Venom symbiote is a powerful entity on its own, and it grants its host a formidable array of abilities, most of which were originally copied from its first human host, Spider-Man.
The personality of Venom is a true composite of the symbiote and its host. With Eddie Brock, the initial personality was one of obsessive, vengeful hatred for Spider-Man. This evolved into the “Lethal Protector” persona: a figure with a strict, if brutal, moral code. Venom (Eddie) will not harm those he deems “innocent” and directs his violence towards criminals. The relationship is symbiotic and codependent; Eddie often tries to rein in the symbiote's more bloodthirsty urges, while the symbiote empowers Eddie and gives him a sense of purpose. With other hosts, the personality shifts. With Mac Gargan (The Scorpion), it was monstrous and cannibalistic. With Flash Thompson (Agent Venom), it was a tool for heroism, though its violent tendencies were a constant struggle to suppress.
The SSU's version of Venom maintains the core power set but with some distinct differences in presentation and personality.
The most significant departure from the original comics is the personality. The SSU Venom is far more comedic and conversational. It has a distinct, fully-formed personality separate from Eddie, with whom it constantly bickers and banters. Their relationship is less about shared hatred and more about two “losers” finding a strange, codependent friendship. Venom is portrayed as curious, impulsive, and possessing a simplistic and violent worldview, which Eddie must constantly manage. Its iconic line, “We will eat both your arms, and then both of your legs, and then we will eat your face right off your head. You will be this armless, legless, faceless thing, rolling down the street like a turd in the wind,” perfectly encapsulates its bizarre mix of horror and dark humor.
While often a loner, Venom has forged several crucial, if often complicated, alliances over the years.
Venom's status as both villain and anti-hero has given him a rich rogues' gallery, defined by his relationships with both heroes and fellow monsters.
Over his long history, Venom has been a part of a surprising number of teams, usually in an anti-hero or government-operative capacity.
This is the quintessential Venom story. After weeks of being stalked by an unseen foe who doesn't trigger his Spider-Sense, a terrified Peter Parker is confronted by Venom. The story masterfully builds tension, culminating in the shocking reveal of Eddie Brock and his tragic backstory. The ensuing fight is brutal and personal, with Venom overpowering Spider-Man physically and psychologically. It established Venom not just as a physical threat, but as a horror movie monster who knew everything about his victim. The issue permanently cemented Venom as an A-list Spider-Man villain.
This six-issue miniseries was a turning point for the character. After making a truce with Spider-Man, Venom relocates from New York to San Francisco. There, he establishes himself as the protector of a subterranean society of homeless people. The series fleshed out Eddie Brock's twisted moral code: while he is happy to brutally murder criminals, he fiercely protects those he deems innocent. This storyline cemented his transition from pure villain to popular anti-hero and introduced the concept of symbiote “children” with the creation of the five Life Foundation symbiotes: Scream, Phage, Riot, Lasher, and Agony.
A massive, 14-part crossover event, Maximum Carnage was the definitive Venom vs. Carnage story of the '90s. Carnage escapes from Ravencroft Asylum and assembles a “family” of sadistic supervillains (including Shriek, Demogoblin, and Carrion) to go on a city-wide killing spree in New York. To stop this overwhelming threat, Spider-Man is forced to team up with Venom, along with other heroes like Captain America, Black Cat, and Cloak & Dagger. The story highlights the ideological clash between Spider-Man's refusal to kill and Venom's belief that lethal force is the only way to stop a monster like Carnage.
Writer Rick Remender revitalized the Venom concept by bonding the symbiote to a new, heroic host: Flash Thompson. As a soldier who idolized Spider-Man, Flash brought a completely new dynamic to the role. He used the symbiote's powers for black-ops missions, but could only maintain the bond for 48 hours at a time before the symbiote's consciousness threatened to take over. This run explored themes of addiction, disability, and redemption, adding incredible depth to both Flash and the symbiote itself, and proving that “Venom” could be a true hero.
The epic finale to Donny Cates' and Ryan Stegman's run on Venom. Knull, the ancient god of the symbiotes, arrives at Earth with an army of symbiote dragons, plunging the entire planet into darkness. The event saw Eddie Brock pushed to his absolute limit, dying and being reborn as a cosmic force. It redefined the entire history and cosmology of the symbiotes in the Marvel Universe, elevating Venom from a street-level anti-hero to a central figure in a cosmic war, ultimately culminating in Eddie Brock becoming the new King in Black.
