The short answer
The principle comes down to one word: the codex. Anyone who has ever carried a symbiote keeps its genetic imprint in their spinal cord, and Carnage, promoted to avatar of Knull, hunts down these former hosts to tear out those fragments and wake his god. Here is how the hunt unfolds.
Contents
There are sagas that send a shiver through the reader, and others that make them bleed. Absolute Carnage belongs firmly to the second category. Published in 2019, written by Donny Cates and drawn with blistering energy by Ryan Stegman, this major Spider-Man event landed like an axe blow. For months, readers watched a methodical slaughter orchestrated by the most unstable killer in the entire Marvel pantheon, now the armed hand of a deity from the depths of space. This was no longer a simple clash between a hero and a blood-red psychopath: it was the announced awakening of a god, the stirring of a cosmic terror that had slept for aeons. Let us dive together into this utterly pitch-black arc, where every page seems to seep blood and no victory is won without a scar.
Origins: who is Carnage, the scarlet butcher?
To grasp the scale of the disaster this event unleashes, you first need to look again at the nature of its antagonist. Cletus Kasady, alias Carnage, is no ordinary supervillain. Even before he met a single symbiote, Kasady was already a serial killer, a deeply disturbed mind who saw chaos and murder as a form of absolute freedom. Where other criminals chase money or power, Cletus wants only one thing: to watch the world collapse in blood.
When this psychopath merges with an offspring of the black symbiote, the result defies belief. Carnage becomes an unstable creature, able to generate organic weapons at will, limitless in violence and utterly unpredictable. Unlike Venom, who eventually develops a twisted but genuine moral code, Carnage has never known the slightest redemption. He is the symbiote in its purest, most destructive form. It is precisely this total absence of restraint that makes him the ideal candidate to serve a force far older and far more terrible than himself.
Cletus Kasady, a killer first and foremost
Already a serial killer before the symbiote, Cletus Kasady has never known redemption, unlike Venom: the ideal servant for Knull.
Knull, the sleeping god who changes everything
At the heart of Absolute Carnage stands a figure Donny Cates had carefully set up in his earlier stories: Knull, the god of the symbiotes. This primordial entity, born before the known universe was even created, is the true creator of the symbiote race. In the mythology Cates unfurls, every symbiote is only a fragment of this dark god's will, a shard of his consciousness scattered across the cosmos.
Knull sleeps, imprisoned far from Earth, but his influence has never stopped creeping through the shadows. The whole plot of Absolute Carnage rests on one chilling idea: waking that god. And to do it, Carnage becomes his avatar, his bloody prophet, his instrument on Earth. This revelation retroactively transforms the entire history of the symbiotes in the Marvel universe. What looked like nothing more than alien parasites suddenly becomes the nervous system of a sleeping deity, waiting for the signal to wake. The threat is no longer local, it is cosmic.

Codexes: the terrifying mechanics of the hunt
The central element that structures the whole story is the concept of the 'codex'. It is a narrative find as simple as it is devastatingly effective. Every time a person has been bonded to a symbiote, even for a moment, a copy of the symbiote god's genetic code is etched into their spinal cord. This imprint, this codex, survives even after the symbiote has left its host. It is an invisible scar, a divine mark written deep into the spine.
Now, these codexes are exactly what Knull needs in order to wake. Carnage's mission therefore becomes appallingly clear: hunt, kill and devour everyone who has ever carried a symbiote, so as to harvest those fragments of code and offer them to his god. Every former host becomes prey. And the list is long, terribly long, because over the decades countless heroes and villains have been bonded, however briefly, to one of these parasites. To measure the scale of that shared history, you need only think of the relationship between Spider-Man and the symbiote, which goes back years and makes the web-slinger a prime target.
This mechanism turns the Marvel universe into one vast hunting ground. Nobody is safe, and every panel can become the stage for a fresh massacre. Carnage does not merely kill: he harvests. He becomes the reaper of a macabre crop whose ultimate goal is to plunge the world into darkness.
An enhanced Carnage, almost invincible
The Carnage of Absolute Carnage is not the killer readers knew. Invested with Knull's power and fed by the codexes he devours, he becomes a force of nature that is almost impossible to stop. His scarlet skin is studded with black patterns that directly echo the god he serves, a visible sign of his transformation into an avatar. Where the classic Carnage was already formidable, this enhanced version operates on a completely different level of threat.
More terrifying still, this new Carnage can turn entire crowds into symbiote creatures. These unfortunates, nicknamed the 'Carnage-ized', become the soldiers of his macabre army, extensions of his corrupted will. He no longer fights alone: he spreads the contamination, multiplying his arms and his fangs across the city. This epidemic dimension gives the event a nightmarish scale, where every civilian in his path can turn into a red and black monster in the butcher's service.
Faced with such power, the heroes quickly realise that none of them can defeat Carnage alone. The only chance of survival lies in unity, in a coalition of everyone who has ever crossed paths with the symbiotes and who now finds themselves at the top of the list of prey.

Eddie Brock and Venom at the heart of the storm
If there is one character this saga places at the centre of the blaze, it is Eddie Brock. As the first and most famous host of the black symbiote, Eddie embodies on his own everything Knull is trying to harvest. But the stakes are even more intimate and more heartbreaking, because the hunt does not target only him: it targets his son too.
Dylan Brock, the young boy whose existence and symbiote nature Eddie discovers, becomes one of Carnage's most valuable targets. Protecting this child while waging war against Knull's avatar puts Eddie in front of a father's dilemma of rare intensity. The hero Venom has become must now fight not only for his own survival, but for that of his bloodline. This family dimension anchors the cosmic horror in a deeply human emotion and gives the arc a resonance that goes far beyond a simple festival of gore.
Throughout the event, Eddie Brock carries the story on his shoulders. His tormented relationship with the symbiote, his past as Spider-Man's rival, his laborious redemption: all these narrative threads converge here. To fully appreciate the richness of this character and his tragic bond with the black parasite, you can explore the whole history of the symbiote and its merging with Eddie that haunts every page of this saga.

Spider-Man, Miles Morales and the coalition of survivors
Of course, no event of this scale in the web-slinger's universe could do without Spider-Man himself. Peter Parker, as a historic host of the symbiote, naturally features among the targets. His presence is all the more crucial because he knows the nature of these creatures, and the dangers they represent, better than anyone. Alongside Venom, he becomes one of the pillars of the resistance against the scarlet butcher.
Young Miles Morales also joins the fight, bringing his energy and his drive to a battle where every ally counts. The hunt extends to many characters linked closely or loosely to the symbiotes, forming a motley coalition of heroes and even former villains, all united by the same existential threat. This forced alliance perfectly illustrates the terrifying logic of the codexes: by making every former host a target, Knull mechanically creates an army of desperate defenders who have no choice but to stick together.
Among the figures to be protected, young Normie Osborn holds a special place. This child, descended from a sadly famous line in the Spider-Man universe, also becomes a key objective that the heroes must keep out of Carnage's claws. Protecting the most vulnerable, Dylan and Normie above all, gives the coalition a purpose that goes beyond mere individual survival: it is about preserving the future against a god who wants only to swallow the world in darkness.

The symbiote galaxy mobilised
One of the great strengths of Absolute Carnage lies in the way the event summons the whole symbiote mythology built up over decades. The hunt for the codexes offers an ideal narrative pretext for bringing together an impressive gallery of creatures linked to the black symbiote. Among them you will find entities as striking as Toxin, Carnage's own offspring, or Anti-Venom, that white, purifying version of the symbiote whose particular powers prove decisive against the contamination.
The saga also revives the memory of creatures born from the Life Foundation's experiments, such as the brutal Riot or the frightening Hybrid, that symbiote born from the fusion of several entities. To these figures are added Carnage's usual travelling companions, such as the technological symbiote Scorn and the deranged accomplice Shriek, whose presence recalls the darkest hours of Cletus Kasady's criminal past.
This massive mobilisation turns the event into a genuine celebration of symbiote lore, where every creature finds its place on the great chessboard of the war against Knull. Readers curious to map out this sprawling universe can also head to the Venom & symbiotes hub, which brings together the many branches of this dark mythology.

A gory legacy: the signature of the Cates era
Absolute Carnage did not come out of nowhere. The event follows on directly from the work Donny Cates carried out on the Venom series, where he had gradually reinvented the entire symbiote mythology. By introducing Knull and revealing the divine origins of the black parasites, Cates had laid the foundations of a far broader story. Absolute Carnage is its spectacular culmination, the moment when every seed he planted finally blossoms in a deluge of blood.
Visually, the arc bears the indelible mark of Ryan Stegman, whose nervous, angular line perfectly matches the violence of the subject. The pages overflow with organic detail, fangs, tentacles and sprays of gore. This is a comic that fully embraces its horror nature, flinching at no disturbing image in its effort to convey the terror the scarlet butcher inspires. That radical aesthetic helped make the event stand apart in Marvel's output at the time.
Beyond the visual shock, a whole thematic project is at work. Absolute Carnage is a meditation on fear, on blood as the raw material of horror, and on the idea of a divine awakening that threatens to swallow all light. The saga draws on the codes of the horror film as much as those of the superhero story, creating an explosive mix that left a deep mark on readers.

In the lineage of the great Carnage crossovers
To place Absolute Carnage properly, it helps to set it back in the long tradition of events centred on the scarlet killer. The character had already been at the heart of sagas that stayed in readers' memories, starting with the legendary Maximum Carnage of the 1990s, a crossover of unprecedented brutality for its time that had already gathered a coalition of heroes against Cletus and his accomplices. To an extent, Absolute Carnage takes up its basic structure while raising it to an unprecedented cosmic scale.
You might also think of Planet of the Symbiotes, that other major story which explored the idea of a symbiote invasion on a grand scale. These earlier events had prepared the ground by getting readers used to seeing the symbiotes as a collective threat rather than simply isolated antagonists. Absolute Carnage builds on that legacy while giving it fresh meaning through the figure of Knull.
This lineage even extends beyond the main continuity. The richness of the symbiote concept has produced countless variations, and enthusiasts will enjoy exploring the alternative versions of Venom that populate the Spider-Man multiverse. Carnage and his dark god thus belong to a teeming mythology, whose contours each new saga enriches.

The prelude to King in Black
If Absolute Carnage marks the peak of the threat embodied by the scarlet butcher, it is in fact only one step in a far broader narrative plan. The event works as a direct prelude to King in Black, the later saga in which Knull himself finally descends on Earth at the head of a colossal army of symbiotes. Everything that plays out in Absolute Carnage, all that frantic harvesting of codexes, prepares the ground for that final confrontation with the god in person.
This long-term construction shows the ambition of Donny Cates, who never conceived his stories as isolated tales but as the chapters of one great symbiote epic. Absolute Carnage sets up the stakes, raises the level of threat and conditions readers to understand that the real apocalypse is still to come. The scarlet butcher, terrifying as he is, is ultimately only the messenger of a far greater horror.
For fans of the web-slinger's universe, this chain of events offers an ideal way into the whole pantheon of antagonists. Carnage can indeed be placed in the great gallery of Spider-Man's enemies, where he holds pride of place among the most dangerous figures Peter Parker has ever faced.

Why Absolute Carnage remains an essential saga
Looking back, Absolute Carnage stands out as one of the most significant events of the decade for the Spider-Man and symbiote universe. It thoroughly renewed a character many saw as a mere scarlet psychopath, giving him an unexpected mythological and cosmic dimension. By making Carnage the avatar of a god, Donny Cates turned a serial killer into the prophet of an apocalypse, raising the stakes considerably.
The arc also shines through its ability to bring a whole mythology together. By gathering so many characters linked to the symbiotes, it offers a fascinating overview of this sprawling universe while telling a coherent, visceral story. The family stakes carried by Eddie and Dylan Brock bring an emotional warmth that offsets the coldness of the slaughter, giving the whole a depth you might not expect from such a gory event.
For anyone who wants to plunge into the magnificent horror of symbiote mythology, Absolute Carnage is essential reading, a high point of darkness and ambition. And to carry the experience further, there is nothing like browsing the Venom & symbiotes collection, which brings together the universe of these fascinating creatures for everyone drawn to the darkness of the symbiote.

Frequently asked questions about Absolute Carnage
Who are the creators of Absolute Carnage?
Absolute Carnage is the work of writer Donny Cates and artist Ryan Stegman, published by Marvel in 2019. The pair had already worked together on the Venom series, where they laid the groundwork for the whole new symbiote mythology. Absolute Carnage is the spectacular culmination of their shared work, an event where the ambitious script of Cates meets the visceral, nervous line of Stegman to produce one of the most striking comics of their era.
What exactly is a codex?
A codex is a copy of the genetic code of the symbiote god Knull, etched into the spinal cord of anyone who has ever been bonded to a symbiote. Even after the symbiote leaves, this imprint remains, like an invisible scar written into the spine. These codexes are precisely what Knull needs in order to wake, which is why Carnage hunts and devours every former host to harvest those precious fragments and hasten the awakening of his god.
Why does Carnage become so powerful in this saga?
In Absolute Carnage, Cletus Kasady no longer fights for himself but as the avatar of Knull, the god of the symbiotes. Invested with that divine power and fed by the codexes he devours, he becomes an almost invincible force, able to turn entire crowds into symbiote creatures known as the 'Carnage-ized'. This enhanced version of the scarlet killer, marked by black patterns on his red skin, far surpasses the classic Carnage and represents a threat of unprecedented scale for every hero in the Marvel universe.
Should you read Absolute Carnage before King in Black?
Yes, Absolute Carnage works as a direct prelude to King in Black, the saga in which Knull himself descends on Earth at the head of an army of symbiotes. Understanding the stakes of Absolute Carnage, particularly the harvesting of the codexes and the nature of the dark god, lets you fully appreciate the final confrontation that follows. Reading the two events in order gives a coherent, progressive experience, where the threat builds to its apocalyptic peak.
