King in Black

• Core Identity: King in Black is a cataclysmic, line-wide Marvel Comics crossover event that reveals the ancient origin of the Symbiotes and pits the entire hero community of Earth against their primordial god and creator, Knull.
• Key Takeaways:
• Role in the Universe: This event serves as the epic conclusion to a multi-year storyline, fundamentally rewriting the history of the symbiote species, establishing their creator knull as a top-tier cosmic threat, and elevating Venom (Eddie Brock) to a galactic-level power.
• Primary Impact: The story's most significant impact was the complete subjugation of Earth by Knull's symbiote hive, the death of several heroes, the revelation of Dylan Brock's true nature, and the ultimate transformation of Eddie Brock into the new King in Black, commander of the entire Symbiote Hive.
• Key Incarnations: The King in Black storyline is, as of now, exclusive to the Earth-616 (Prime Comic Universe). The Marvel Cinematic Universe (MCU) has not adapted this event, though it has introduced foundational elements like the All-Black Necrosword and a piece of the Venom symbiote, creating a potential but unrealized path for a future adaptation.

The King in Black event was the culmination of writer Donny Cates and artist Ryan Stegman's critically acclaimed run on the Venom comic series, which began in 2018. From their very first issue, Cates and Stegman began seeding the mythology of a dark, primordial god of the abyss who created the symbiotes. This entity, Knull, was a deliberate move away from the established lore of the Klyntar, a benevolent alien race who “cleansed” symbiotes of their corruption. Cates's retcon posited that the Klyntar were merely a prison, a cage of symbiotes that had broken free from their creator's malevolent influence. The character of Knull was first fully revealed in Venom Vol. 4 #3-4 (2018). The creative team, including inker JP Mayer and colorist Frank Martin, crafted a terrifying, nihilistic villain inspired by cosmic horror and heavy metal aesthetics. His design, a gaunt figure with a skeletal grin, long white hair, and a red draconic sigil on his chest, instantly became iconic. The direct prelude to the event was absolute_carnage (2019), another Cates and Stegman collaboration. This storyline saw a resurrected Cletus Kasady, bonded to the Grendel symbiote dragon and empowered by Knull, hunting down every previous symbiote host to collect their “codex” remnants. This act was designed to free Knull from his eons-long imprisonment within the planet Klyntar. The success of Absolute Carnage set the stage for the even larger, more ambitious King in Black crossover, which was officially announced as Marvel's major winter event for 2020-2021. The main series ran for five issues from December 2020 to April 2021, supported by dozens of tie-in issues across the Marvel line, showcasing the global and cosmic scale of Knull's invasion.

The narrative origins of the King in Black event stretch back to the very beginning of the Marvel Universe, predating creation itself.

Before the universe existed, there was only the void—an endless, cold darkness. And within it, there was Knull. When the celestials began the act of creation, bringing light and life into the void, Knull viewed it as an intrusion, a trespass against his kingdom of nothingness. Enraged, he forged the first symbiote from his own shadow, shaping it into a living blade of darkness: All-Black, the Necrosword. With this weapon, he decapitated one of the invading Celestials, a feat that marked him as a primordial force of cosmic destruction. For eons, Knull waged a one-god war against the light. He created an army of symbiotes, creatures of the living abyss, and bound them to his will, forming a collective Hive Mind with him at its center. These were not the Klyntar of later lore; they were extensions of his nihilistic rage. He used them to conquer and consume countless civilizations, enslaving lesser gods and using his symbiote dragons to travel the stars. One of his dragons, the Grendel, crashed on medieval Earth, leading to an encounter with a young Thor Odinson. Thor's divine lightning severed Knull's connection to the Grendel, revealing a critical weakness of the Hive: sonics and intense heat/energy could disrupt the link between Knull and his creations. This revelation spread across the universe. Symbiotes, briefly freed from Knull's control, began bonding with “worthy” hosts, learning concepts of nobility and honor. These free symbiotes banded together and turned on their creator, imprisoning him at the center of a planet-sized cage made of billions of their own bodies. They named this planet Klyntar—the word for “cage” in their language. For millennia, Knull remained dormant at the heart of Klyntar, his consciousness dreaming in the abyss while the Klyntar civilization propagated a false history of their noble origins to hide the terrifying truth. His awakening was a slow, deliberate process. S.H.I.E.L.D.'s discovery and weaponization of the Grendel dragon symbiote on Earth sent ripples through the Hive, stirring Knull. The events of Absolute Carnage were the final key. By collecting the codices left in former hosts, Carnage destroyed the Klyntar prison, shattering the planet and unleashing the Symbiote God upon the universe once more. Knull immediately reformed his Hive, corrupted the free symbiotes, and set a direct course for the one planet that had defied him most: Earth.

The King in Black event has not occurred in the Marvel Cinematic Universe. The MCU's continuity and the Sony Spider-Man Universe (SSU) have presented a very different, more fragmented origin for the symbiotes. However, several key concepts exist that could be used for a future adaptation.

• The All-Black Necrosword: This weapon, Knull's first creation in the comics, appears as the primary weapon of Gorr the God Butcher in Thor: Love and Thunder (2022). Its origins are depicted differently; it is an ancient, corrupting weapon that calls to those with vengeful hearts. The film makes no mention of Knull or symbiotes, and its design is more of a traditional sword than the living, amorphous weapon of the comics. The MCU establishes the sword's ability to corrupt its wielder and create shadow monsters, which share a visual and conceptual similarity to Knull's creations. This provides the strongest, most direct link to the King in Black's comic lore.
• Symbiotes in the MCU: The symbiote itself was properly introduced into the MCU in the post-credits scene of Spider-Man: No Way Home (2021). Tom Hardy's Eddie Brock and Venom are briefly transported to the MCU, and when they are returned to their universe, a small piece of the Venom symbiote is left behind. This establishes that symbiotes now exist in the MCU (Earth-199999), but their origin is tied to the SSU's continuity, where they are an alien species discovered by the Life Foundation. There is currently no mention of Knull, the Hive, or a creator god in either the MCU or SSU.

A potential MCU adaptation of King in Black would require a significant retcon. It would need to connect the All-Black Necrosword from Thor: Love and Thunder to the symbiote piece from No Way Home, establishing that the sword is the progenitor of the symbiote race and that its original master, Knull, exists somewhere in the cosmos. This would be a departure from the comics' timeline but would effectively use the disparate elements already introduced on screen.

The King in Black event was a tightly paced, brutal invasion that unfolded over a short period but had lasting repercussions.

1. Arrival and Overwhelm: The event begins with Knull's fleet of symbiote dragons arriving in Earth's orbit. The planet's most powerful defenders, including the avengers and x-men, mount an immediate defense. Knull's power is shown to be overwhelming. He effortlessly tears the Sentry, one of Earth's strongest heroes, in half. He then unleashes a symbiote “living death” wave, a massive dome of symbiote goo that covers the entire planet, severing it from sunlight and communication with the outside galaxy. 2. The Fall of Heroes: Knull's symbiotes possess and corrupt numerous heroes and villains, turning them into his “Void Knights.” This includes powerful figures like Captain America, Doctor Strange, and several X-Men. Eddie Brock confronts Knull directly, but Knull reveals he has been watching Eddie for years, recognizing him as his most effective host. Knull rips the Venom symbiote from Eddie and seemingly kills him by throwing him from a skyscraper. 3. The Resistance Forms: With the major hero teams decimated and scattered, the resistance becomes fragmented. Iron Man (Tony Stark) uses his Extremis armor to bond with and control one of the symbiote dragons. A small team led by Blade and other supernatural heroes attempts to fight back. The X-Men on Krakoa, led by Cyclops and Storm, manage to hold their own, using Jean Grey's psychic power to resist Knull's Hive Mind. 4. The God of Light: Eddie Brock's consciousness survives, jumping between different symbiote hives. He eventually learns of the Enigma Force, the cosmic power that creates Captain Universe. This force is the polar opposite of Knull's void—it is the God of Light. It has been searching for a perfect host to be its soldier in the war against the darkness. 5. Dylan Brock's Power: Meanwhile, on Earth, Eddie's son Dylan Brock is revealed to be the key. As a human-symbiote hybrid born on Earth, he has the unique ability to not only control symbiotes but to completely sever their connection to Knull and destroy them. Knull recognizes Dylan as his greatest threat and makes capturing him his top priority. 6. The Final Confrontation: The remaining heroes rally to protect Dylan. The Silver Surfer arrives, heralding the coming of the Enigma Force. In a climactic moment, the God of Light chooses Eddie Brock as its host, resurrecting him as the new Captain Universe. Wielding the power of the Enigma Force, Eddie creates a symbiote-Mjolnir hybrid and battles Knull. He discovers that to truly defeat Knull, he needs more than the Enigma Force; he needs the Hive. Dylan uses his power to sever Knull's connection to every symbiote in the universe, freeing them. Eddie then allows the Venom symbiote to bond with him, becoming the new center of the Hive. 7. Victory and Ascension: As the new King in Black and Captain Universe, Eddie Brock easily overpowers Knull, flying him into the sun and destroying his physical form. The symbiote dome over Earth recedes, and the possessed heroes are freed.

• The Death of the Sentry: This opening act immediately established the stakes. The Sentry was arguably Earth's most powerful hero, and Knull killed him with zero effort. It told the readers and the heroes that this was not a fight they could win with brute force alone.
• Iron Man's Symbiote Dragon: Tony Stark's ingenuity in taking control of one of Knull's primary weapons provided the resistance with a much-needed mobile command center and a symbol of hope. It demonstrated that Knull's army was not invincible.
• Jean Grey's Psychic Defense: The X-Men's stand on Krakoa was a crucial turning point. Jean Grey's telepathic power acted as a “psychic circuit breaker,” preventing Knull from instantly overwhelming the minds of everyone on the island and creating a safe zone for heroes to regroup.
• Eddie Brock Becomes Captain Universe: The intervention of the Enigma Force was the deus ex machina the heroes needed. It was the only power in the universe that could match Knull's primordial darkness, and by bonding with Eddie, it created the ultimate champion for the light.
• Dylan Frees the Hive: This was the most critical moment of the final battle. It wasn't just about killing Knull; it was about saving the symbiotes. Dylan's unique power transformed the symbiotes from Knull's army into Eddie's army, turning Knull's greatest weapon against him.

The end of the King in Black event dramatically altered the status quo for Venom and the cosmic landscape.

• Eddie Brock, The New King in Black: Eddie Brock is now the god-like center of the Symbiote Hive Mind. He can perceive the universe through the eyes of any symbiote, travel vast distances instantly, and command the entire species. He dedicates his new power to using the Hive as a force for good, protecting the innocent across the galaxy. His physical body remains on Earth, while his consciousness patrols the cosmos.
• The Symbiote Race Reborn: Freed from Knull's millennia of control, the symbiote species is no longer inherently evil. Under Eddie's guidance, they begin a new chapter as a galactic peacekeeping force.
• Dylan Brock's Future: Dylan remains on Earth, now bonded with the Venom symbiote while his father is in space. He becomes the new street-level Venom, grappling with the immense and terrifying power he possesses.
• Earth's Recovery: The world is left to rebuild from a global-scale invasion. The event left deep psychological scars on the hero community and the civilian population, who experienced a planet completely encased in living darkness.

Knull's army was a seemingly endless tide of darkness, comprised of several terrifying tiers.

• Knull, the King in Black: The Symbiote God and primordial creator of the void. His power was immense, rivaling that of Celestials. He commanded the Hive Mind, possessed superhuman strength and durability, and could manifest weapons from the living abyss.
• Symbiote Dragons: Knull's primary vessels for interstellar travel and large-scale destruction. These massive, winged symbiote constructs could cover entire cities and were capable of fighting cosmic-level heroes like Thor.
• Void Knights: Heroes and villains possessed by Knull's symbiotes. Knull targeted the most powerful and strategic individuals, turning Earth's greatest defenders into its most terrifying enemies. Notable Void Knights included members of the Avengers, X-Men, and Fantastic Four.
• The Swarm: The countless lesser symbiotes that formed the “symbiote dome” and swarmed cities, possessing civilians and overwhelming defenders through sheer numbers.

The defense of Earth relied on a desperate and fractured coalition of heroes who managed to survive the initial onslaught.

• Eddie Brock / Venom: The central protagonist. His journey from being Knull's target to becoming his replacement was the core arc of the story. His intimate knowledge of the Hive was invaluable.
• Dylan Brock: Eddie's son and the story's secret weapon. His unique biology made him the only being capable of permanently severing a symbiote's connection to Knull's Hive.
• Tony Stark / Iron Man: A key strategic leader. By capturing a symbiote dragon and using his Extremis technology, he provided the resistance with a powerful weapon and a mobile base of operations.
• The X-Men: The mutants of Krakoa proved to be one of the most effective fighting forces. Jean Grey's psychic defenses, Storm's control over the weather to create lightning (a symbiote weakness), and Cyclops's strategic command were instrumental in holding the line.
• Doctor Strange: Though he was possessed early on, Strange's magical expertise was crucial. Before his fall, he was instrumental in understanding the magical and cosmic nature of the threat. After being freed, he helped cleanse other heroes.

While Earth's heroes were the primary focus, the conflict drew the attention of several cosmic entities.

• The Enigma Force (The God of Light): The direct antithesis to Knull. A cosmic force of creation and life, it represents the light that Knull seeks to extinguish. It intervened by transforming Eddie Brock into Captain Universe, providing the power necessary to challenge Knull on equal footing.
• Silver Surfer: Acting as a herald for the Enigma Force, the Surfer was one of the few beings who understood the scale of Knull's power from the beginning. He fought to protect the God of Light until it could find a suitable host.
• The Celestials: Though they did not directly intervene in the modern-day conflict, their ancient war with Knull was the foundational event of his origin. Knull's army included several ancient, corrupted Celestials he had defeated eons ago, which he used as monstrous titans in his invasion.

The scale of the King in Black event was explored through numerous tie-in comics, which fleshed out the global impact of the invasion.

This 2019 event is the essential prequel. In it, Cletus Kasady, resurrected and bonded with the Grendel symbiote, acts as a dark herald for Knull. His mission is to hunt down everyone who has ever worn a symbiote—from Peter Parker to Norman Osborn—and extract the genetic “codex” left in their bodies. By collecting these codices and interfacing with the Grendel, he is able to breach the Klyntar prison and fully awaken Knull. The storyline establishes the lore of the Hive Mind, the codex, and the terrifying scope of Knull's influence long before he physically arrives.

The entire 2018 Venom series by Cates and Stegman serves as “Volume 0” for King in Black. Key arcs include:

• Rex (Issues #1-6): Introduces the Grendel symbiote dragon and the existence of Knull, completely rewriting the symbiote origin story.
• The Abyss (Issues #10-12): Eddie travels into Knull's mind, learning more about the Hive and his creator's malevolent intentions.
• Venom Island (Issues #21-25): A direct follow-up to Absolute Carnage, where Eddie must fight a Carnage-infected version of the Venom symbiote, further strengthening his resolve to oppose the coming darkness.

• King in Black: Namor: A flashback series revealing an ancient war between the Atlanteans of old and Knull's forces, establishing that the King in Black had targeted Earth in the distant past.
• King in Black: Thunderbolts: With the Avengers and other major teams incapacitated, Mayor Wilson Fisk (the Kingpin) assembles a new team of Thunderbolts from Ravencroft Institute's inmates to serve as New York's last line of defense, with predictably chaotic results.
• King in Black: Ghost Rider: Johnny Blaze, the current king of Hell, fights back against a demonic invasion spurred on by Knull's chaos, showcasing the supernatural ramifications of the event.
• S.W.O.R.D.: The newly re-formed space agency deals with the galactic fallout, trying to prevent Knull's symbiote wave from spreading beyond Earth's solar system.

While a direct, faithful adaptation of King in Black has not yet been produced outside of comics, its characters and themes have begun to appear in other media.

Knull and the King in Black storyline have been popular additions to several mobile and console video games, often serving as ultimate boss characters or event themes.

• Marvel's Contest of Champions: Knull was added as a playable character, depicted as one of the game's most powerful “Cosmic” champions. His move-set is directly inspired by his abilities from the comic event.
• Marvel Strike Force: The “King in Black” storyline was a major event in the game, introducing Knull as a legendary character and new “Symbiote” team members to reflect his influence.
• Marvel's Spider-Man 2 (2023): While Knull does not appear, the game's main plot involves the Venom symbiote. A late-game side mission reveals a “Symbiote Spiral” logo that is identical to Knull's draconic sigil, leading to intense fan speculation that Knull will be a villain in a future installment or DLC.

The groundwork for a cinematic version of King in Black is fragmented but present across multiple film continuities. An adaptation would require unifying these threads:

• MCU & SSU Connection: First and foremost, the MCU would need to establish a clear link between the All-Black Necrosword (owned by Gorr) and the symbiotes (from the SSU). A future story could reveal that the sword was the first symbiote and that its destruction or disappearance did not eliminate its creator, Knull.
• Building the Lore: The MCU's single piece of symbiote would need to multiply and spread, creating the foundation for a Hive. The concept of a Hive Mind and a Symbiote God would need to be introduced, likely in a future Spider-Man or Venom film.
• A Cosmic-Level Event: Given the scale of the invasion, a King in Black movie would have to be an Avengers-level crossover event. It would require the full roster of Earth's heroes and likely cosmic characters like Captain Marvel, Thor, and the Guardians of the Galaxy to properly convey the threat level Knull represents. It would be a natural fit for the MCU's ongoing “Multiverse Saga” or a future cosmic saga, positioning Knull as a Kang-level or Thanos-level threat.
