Knull, the ancient God of the Symbiotes, completely transformed the cosmic hierarchy of Marvel Comics when he burst onto the page in 2018. Created by writer Donny Cates and artist Ryan Stegman, this primordial deity retroactively tied together the origins of Venom, Carnage, and Gorr the God-Butcher. Rather than being simple alien organisms dropped onto a meteorite, symbiotes were revealed to be living weapons forged by a dark god who wanted to plunge the entire universe back into eternal void.
Understanding Knull requires looking past the superficial hype and examining his deep-rooted place in Marvel continuity. From his creation of All-Black the Necrosword to his cinematic debut played by Andy Serkis in Venom: The Last Dance, Knull stands out as one of the most destructive entities ever introduced to modern comic lore.
Who Is Knull in Marvel Lore?
Long before the current iteration of the universe existed, Knull floated comfortably in an endless void of primordial darkness. When the cosmic entities known as the Celestials arrived to forge the seventh cosmos with light and matter, Knull viewed them as unwelcome intruders ruining his quiet kingdom.
When the Celestials attempted to subdue him, Knull reached into his living shadow and pulled out a piece of darkness, hardening it into the very first symbiote: a living weapon shaped like a sword. He used this blade—later named All-Black the Necrosword—to decapitate a Celestial. Cast out into space alongside the severed head (which later became the spaceport Knowhere), Knull used the cosmic forge inside the dead god's skull to temper his weapon and begin a relentless crusade slaughtering gods across the stars. Experts at Bloomberg have shared their thoughts on this matter.
The True Origin of the Symbiotes
Knull didn't design his dark creations to be friendly alien suits. He engineered them as an invasive, hive-minded army. By blanketing planets in living darkness, he could corrupt local populations and control them remotely.
However, his reign over his creations came to an abrupt end. During a battle on an unnamed world, Knull was separated from All-Black (which was eventually found and wielded by Gorr the God-Butcher). Without their master's direct iron grip, the symbiotes experienced exposure to benevolent life forms across the galaxy. They learned about empathy, honor, and light.
Horrified by their master's cruelty, the symbiotes rebelled. They swarmed Knull and trapped him inside an artificial prison planet they named Klyntar—which translates to "cage" in their language. There he stayed dormant for millennia, whispering into the collective hive mind, waiting for the day his bonds would finally break.
Knull's Core Powers and Abilities
Knull is not just an ordinary alien warlord; he operates on a tier closer to cosmic abstracts like Oblivion. His physiology and capabilities make him nearly impossible to defeat through brute force alone:
- Living Darkness Manipulation: Knull can generate, shape, and weaponize absolute darkness, plunging entire planets into pitch-black despair and freezing temperatures.
- Symbiote Hive Control: As the creator of the race, Knull holds absolute dominion over all symbiotes, able to override any host—including Venom and Carnage—with a single thought.
- God-Slaying Combat Prowess: Armed with millennia of combat experience and weapons forged from pure shadow, he possesses the physical strength to effortlessly overpower heavy hitters like the Sentry.
- Immortality and Regeneration: Having existed before the current universe, Knull does not age and can instantly regenerate from catastrophic physical trauma using living abyss matter.
The King in Black Event and Beyond
When Knull finally broke free from his prison in the King in Black crossover event, he didn't just attack—he completely overwhelmed Earth's defenses in a matter of hours. He arrived riding a horde of symbiote dragons, encased the entire planet in a suffocating dome of darkness, and quickly neutralized major heroes like the Avengers, Fantastic Four, and X-Men.
He even ripped the Sentry in half to absorb the Void. Defeating him required a massive coalition, culminating in Eddie Brock bonding with the divine Enigma Force to become Captain Universe and vaporizing the dark god once and for all. Even so, cosmic characters in Marvel rarely stay dead for long, and subsequent comic runs continue to deal with the lingering echoes of the King in Black's dark legacy.
