====== Klyntar ======
===== Part 1: The Dossier: An At-a-Glance Summary =====
  *   **Core Identity:** **The Klyntar are a symbiotic, amorphous alien species from the darkest void of space, created by the primordial entity [[knull|Knull]], who once sought to create a perfect warrior race by bonding with noble hosts but have been largely corrupted into the parasitic creatures commonly known as Symbiotes.**
  *   **Key Takeaways:**
    *  **Role in the Universe:** Originally intended by their creator, Knull, to be living weapons and armor, the species rebelled to become the Klyntar, a society dedicated to forming symbiotic partnerships with worthy individuals to act as galactic peacekeepers called the [[agent_venom|Agents of the Cosmos]]. However, a corrupted Klyntar, when bonded with an unworthy or unstable host, becomes a destructive parasite, which is the form most famously exemplified by [[venom]] and [[carnage]].
    *  **Primary Impact:** The Klyntar's most significant impact on the Marvel Universe is the introduction of Symbiotes, which have created some of its most formidable heroes and terrifying villains. Their existence fundamentally challenges the nature of identity, symbiosis, and corruption, affecting characters from [[spider-man|Spider-Man]] to the [[guardians_of_the_galaxy|Guardians of the Galaxy]].
    *  **Key Incarnations:** The **Earth-616 (comics)** Klyntar have a vast, cosmic, and quasi-divine origin story tied to the beginning of the universe, Knull, and the Celestials, with a defined culture of nobility that can be corrupted. In contrast, the **Marvel Cinematic Universe (and its adjacent Sony films)** depicts the Symbiotes simply as a predatory, parasitic alien species seeking to invade and consume other worlds, with no mention of their noble Klyntar potential or their primordial creator.
===== Part 2: Origin and Evolution =====
==== Publication History and Creation ====
The creature that would eventually be revealed as a member of the Klyntar species first appeared not as a character, but as an object: a new, living black costume for Spider-Man. Its debut was in //The Amazing Spider-Man #252// (May 1984), but its origin was detailed in the concurrent maxiseries //Marvel Super Heroes Secret Wars #8// (December 1984), created by writer Jim Shooter and artist Mike Zeck. Initially conceived by a fan named Randy Schueller, the idea of a black costume made of unstable molecules was purchased by Marvel. Shooter and the creative team evolved this concept into a sentient alien lifeform.
For years, the creature was known simply as the "alien costume" or "the Symbiote." It wasn't until the explosive debut of Venom in //The Amazing Spider-Man #299-300// (1988) by David Michelinie and Todd McFarlane that the Symbiote's nature as a vengeful, character-driven entity was solidified. The concept of a full-fledged Symbiote species was explored in the 1995 storyline "Planet of the Symbiotes," which depicted them as a hive-minded invading force.
The most significant evolution came decades later. The term "Klyntar" and the idea of a noble Symbiote society were introduced in //Guardians of the Galaxy (Vol. 3) #23// (2015) by Brian Michael Bendis. This retcon reframed the entire species, establishing that the monstrous Symbiotes seen on Earth were corrupted, outcast members of a benevolent race. This concept was further, and more dramatically, redefined by writer Donny Cates and artist Ryan Stegman in their landmark //Venom// run beginning in 2018. They introduced Knull, the Symbiote god and creator, in //Venom (Vol. 4) #3-4//, establishing a dark, cosmic horror origin that predates most of the known universe and tied the Symbiotes' creation to a war against the [[celestials|Celestials]]. This modern origin is now considered the definitive canon for the species.
==== In-Universe Origin Story ====
=== Earth-616 (Prime Comic Universe) ===
The true origin of the Klyntar is an epic of cosmic horror, rebellion, and redemption, stretching back to the dawn of time.
Before the universe existed, there was only the endless, dark abyss—the Void. Ruling this primordial nothingness was the entity known as Knull. When the Celestials arrived and began the act of creation, flooding his darkness with light and life, Knull was enraged. He retaliated by forging a blade from his own shadow, the first Symbiote, called **[[all-black_the_necrosword|All-Black, the Necrosword]]**. With this living weapon, he decapitated a Celestial, an act that marked the beginning of his war on creation.
From this first creation, Knull began to experiment, creating an army of amorphous, parasitic creatures from the "living abyss." These were the first Symbiotes. He bound them to his will, forming a monolithic, hive-minded army known as the Symbiote Imperium. Their consciousness was linked through a psychic network called the Hive-Mind, or "the Void." For eons, Knull used his Symbiote dragons (Grendels) and other monstrous creations to conquer worlds, extinguish stars, and consume entire civilizations, blanketing the universe in his living darkness. The Symbiotes were not partners; they were slaves, extensions of Knull's malevolent will, designed to forcibly bond to and consume their hosts.
Millennia ago, Knull's forces were drawn to Earth where he battled a young, thunder god-empowered [[thor|Thor]]. Thor's divine lightning severed Knull's connection to his Grendel, and the shockwave of this separation rippled through the Symbiote Hive-Mind across the galaxy. For the first time, the Symbiotes experienced existence without their tyrannical god's direct control. They saw the potential for something other than conquest. Inspired by the nobility of the hosts they had previously consumed, a faction of Symbiotes rebelled against their creator.
This rebellion culminated in the Symbiotes overwhelming Knull, encasing him in a planet-sized prison of their own living bodies. They moved this prison to the edge of the galaxy, naming it Klyntar—the Symbiote word for "cage." Over time, the name Klyntar came to refer to their new society and species as a whole. They dedicated themselves to a new, noble purpose: to purge Knull's darkness from their collective consciousness and atone for their past. They would now seek out only worthy, noble hosts from across the universe—individuals of sound mind and moral fortitude. By bonding with these hosts, they would form a perfect union, creating the "Agents of the Cosmos," a galactic force for good.
However, the connection to Knull could never be fully severed. If a Klyntar bonded with an unworthy, unstable, or malevolent host, the host's negative emotions could corrupt the Symbiote. This corruption would sever its connection to the Klyntar hive-mind, driving it insane and reverting it to its predatory, parasitic nature. These corrupted Symbiotes, like the one that would become Venom, were feared and cast out, left to wander the cosmos as monsters, forever cut off from the light of their reformed culture.
=== Marvel Cinematic Universe (MCU) ===
The origin of the Symbiotes in the MCU (as established in Sony's Spider-Man Universe films, which have a tenuous connection to the mainline MCU) is far simpler and devoid of the cosmic mythology present in the comics.
The Symbiotes are an alien species from an unnamed planet. As depicted in the film //Venom// (2018), they are a species of amorphous, parasitic lifeforms that require a host organism to survive in oxygen-rich atmospheres like Earth's. They were discovered on a comet by the Life Foundation, a bio-engineering corporation led by Carlton Drake. Probes from the Foundation brought back four Symbiote specimens.
Their initial motivation is presented as pure survival and conquest. The Symbiote leader, Riot, reveals their overarching plan: to bring millions more Symbiotes to Earth to bond with humans and consume the planet's resources, viewing humanity as inferior and disposable. They are portrayed not as fallen nobles, but as a straightforward invading force.
There is no mention of Knull, the Celestials, the Necrosword, or a noble Klyntar society. The concept of a "perfect match" between a Symbiote and a host exists, but it is framed in terms of biological compatibility rather than moral worthiness. Eddie Brock and the Venom Symbiote are a perfect match, allowing them to bond without the host's body deteriorating.
The Venom Symbiote is characterized as a "loser" on its home planet, which is why it decides to betray its own kind and help Eddie save Earth. This character beat serves a similar narrative function to the comic concept of a Symbiote choosing a different path, but its roots are in personal rejection rather than a species-wide philosophical rebellion against a dark god. The core nature of the MCU Symbiote is that of a parasite that can, through its bond with a good-willed host, evolve into a reluctant anti-hero.
===== Part 3: Physiology, Culture & Hive-Mind =====
=== Earth-616 (Prime Comic Universe) ===
==== Physiology ====
  * **Amorphous Composition:** Klyntar are amorphous, symbiotic endoparasites composed of a carbon-based, organic material. They have no default shape of their own and can alter their form, size, and density at will. They can mimic any form of clothing, generate tendrils, bladed weapons, and shields from their own biomass.
  * **Symbiotic Sustenance:** A Klyntar's primary form of sustenance is not physical food, but rather specific neurochemicals produced by their host's brain, primarily phenethylamine and adrenaline. This is why they are drawn to hosts who experience intense emotions or high-stakes situations. A corrupted Symbiote's hunger can become voracious, leading it to physically consume its host from the inside out.
  * **Genetic Memory:** Klyntar possess an innate genetic memory, allowing them to absorb and retain the memories, skills, and even superpowers of their hosts. This knowledge is passed down to their offspring and can also be shared across the Hive-Mind. This is how the Venom Symbiote granted Spider-Man's powers to subsequent hosts like Eddie Brock.
  * **Enhanced Abilities:** When bonded with a host, a Klyntar grants them a suite of superhuman abilities, including:
    *  Vastly increased strength, speed, durability, and agility.
    *  A potent regenerative healing factor.
    *  The ability to adhere to any surface.
    *  Limited shapeshifting and camouflage.
    *  Immunity to detection by Spider-Man's "spider-sense." ((This is a specific adaptation the Venom symbiote developed due to its prolonged bond with Peter Parker.))
  * **Innate Weaknesses:** Klyntar have two primary weaknesses ingrained in their biology from the time of their creation. Knull forged the first Symbiotes in the heat of a celestial forge and hammered them with sound. As a result, the entire species is intensely vulnerable to:
    *  **Sonics:** High-frequency sound waves can cause a Klyntar's molecular structure to destabilize, causing them extreme pain and forcing them to separate from their host.
    *  **Fire/Intense Heat:** Extreme heat can cause a Klyntar's biomass to disintegrate, effectively killing it.
==== Culture and Philosophy ====
The core of modern Klyntar culture is the rejection of Knull's tyranny and the pursuit of a "perfect union." They believe that by bonding with a truly noble and morally just individual, the Klyntar and its host can become something greater than the sum of their parts—a perfect warrior. These bonded pairs, the Agents of the Cosmos, patrol the universe, protecting the innocent and maintaining peace.
This philosophy is built on a foundation of deep-seated racial trauma and fear. They are terrified of their origins and the ever-present influence of their creator, Knull, who lies imprisoned at the center of their collective consciousness. The concept of "corruption" is their greatest taboo. A Symbiote that bonds with a flawed host and is severed from the Hive-Mind is seen as a failure and a monster, a cancerous cell that must be purged. This leads to a somewhat rigid and unforgiving societal structure, as they will actively hunt down and attempt to "cleanse" or kill their corrupted brethren to prevent them from spreading their "sickness."
==== The Hive-Mind ====
The Klyntar Hive-Mind, also called the Void, is a trans-galactic psychic network that connects every single uncorrupted Symbiote. It functions as a collective consciousness, allowing them to share information, memories, and experiences instantaneously across vast distances. This network is what allows the Klyntar to function as a cohesive society despite being spread throughout the universe. The planet Klyntar serves as the central nexus point for this network.
However, the Hive-Mind is also their greatest vulnerability. At its center is the prison of Knull. Even in his slumber, he can subtly influence the Hive, spreading his darkness and corrupting whispers. When he finally awoke during the //King in Black// event, he was able to instantly seize control of nearly every Symbiote in the universe through this very network, turning the Klyntar's greatest strength into his ultimate weapon.
=== Marvel Cinematic Universe (MCU) ===
==== Physiology ====
The physiology of the MCU Symbiotes is broadly similar to their comic counterparts but with a greater emphasis on their parasitic nature.
  * **Host Dependency:** MCU Symbiotes are shown to be highly dependent on a compatible host for survival on Earth. An incompatible host will be quickly consumed and killed, and the Symbiote itself cannot survive for long without a host in Earth's atmosphere.
  * **Biological Compatibility:** The concept of a "perfect match" (like Eddie and Venom) is crucial. This perfect biological compatibility allows for a stable, long-term bond where the host is not harmed and the Symbiote can function at peak efficiency.
  * **Extreme Vulnerabilities:** While also weak to sound and fire, the MCU versions seem even more acutely susceptible. Relatively low-frequency sounds (like an MRI machine) and moderate flames are shown to be debilitating, making these weaknesses more practical and frequently exploited plot devices.
  * **Sustenance:** The Venom Symbiote expresses a desire to eat people's brains and internal organs, though it is often satisfied with vast quantities of tater tots and chocolate, suggesting a need for phenethylamine, similar to the comics, but framed in a more darkly comedic, cannibalistic manner.
==== Culture and Philosophy ====
The MCU has not depicted a Klyntar culture. The Symbiotes are introduced as a monolithic, invasive species. Their philosophy is one of conquest and consumption, led by individuals like Riot. Their society appears to be a simple hierarchy based on strength and purpose. There is no evidence of a noble past or a desire to be anything other than what they are. Venom's decision to protect Earth is an act of individual rebellion, not a reflection of a broader cultural movement within his species. He helps humanity because he has grown to like Earth and his host, Eddie, and considers himself a "loser" back home.
==== The Hive-Mind ====
A form of hive-mind communication is shown to exist. Riot, upon arriving on Earth, is able to sense the location of the other Symbiotes and communicate his plan. However, it is depicted more as a simple telepathic communication network for coordinating an invasion rather than the vast, shared consciousness of the comic book Klyntar. It does not appear to have the same depth, history, or vulnerability related to a dark creator god.
===== Part 4: Key Relationships & Network =====
==== Core Allies & Notable Hosts ====
  * **[[flash_thompson|Flash Thompson (Agent Venom)]]:** Arguably the most successful example of the Klyntar ideal in practice. As Agent Venom, the war veteran Flash Thompson bonded with the Venom Symbiote and, through a combination of suppressive drugs and immense willpower, was able to redeem it. Together, they served as a government operative, a member of the Secret Avengers, and eventually traveled to space where they joined the Guardians of the Galaxy and visited the planet Klyntar, where the Symbiote was "cleansed" and reconnected to the Hive-Mind.
  * **[[spider-man|Peter Parker]]:** The original Earth host for the Venom Symbiote. Spider-Man's innate nobility and sense of responsibility were what the Symbiote initially found so attractive. However, his strong will and eventual violent rejection of the Symbiote deeply traumatized it, twisting its feelings of love into hatred and setting it on its dark path with Eddie Brock.
  * **[[eddie_brock|Eddie Brock]]:** While initially a corrupted host driven by a mutual hatred for Spider-Man, Eddie Brock's bond with the Venom Symbiote evolved over decades. They developed a complex, co-dependent relationship, eventually becoming a lethal protector. After the events of //King in Black//, Eddie Brock transcended mortality and briefly became the new center of the Hive-Mind, effectively the new "King in Black," with the power to control all Symbiotes.
==== Arch-Enemies & Corrupting Forces ====
  * **[[knull|Knull]]:** The ultimate adversary. Knull is the creator, god, and tyrant of the Symbiotes. He is the source of their darkness and their primordial purpose. The entire existence of the reformed Klyntar society is a rebellion against everything he stands for. His reawakening in the modern era threatened to undo millennia of progress and plunge the entire universe back into his living abyss.
  * **[[carnage|Carnage (Cletus Kasady)]]:** The ultimate perversion of the Klyntar ideal. The Carnage Symbiote is the offspring of Venom, bonded with the psychopathic serial killer Cletus Kasady. This union of a corrupted Symbiote with a completely depraved human created a being of pure, nihilistic chaos. Carnage represents the Symbiote's worst-case scenario and has often acted as a herald or high priest for Knull.
  * **The Poisons:** A crystalline, parasitic species from another dimension (Earth-17952). The Poisons are the natural predators of the Klyntar. They hunt and consume Symbiotes and their hosts, assimilating them into their own collective consciousness. They represent a threat so great that it has forced heroes and villains bonded with Symbiotes to unite against them.
==== Affiliations ====
  * **Agents of the Cosmos:** The official title for the noble warrior order formed by the Klyntar and their worthy hosts. This is the primary affiliation of the uncorrupted species.
  * **The Symbiote Imperium:** The name of Knull's original empire of conquest during the dawn of the universe. When Knull returns, he re-establishes this Imperium with all the Symbiotes he brings back under his control.
  * **Guardians of the Galaxy:** The Klyntar have a notable affiliation with this team through Agent Venom (Flash Thompson), who served as the team's liaison to Earth and discovered the true nature of his Symbiote while serving with them.
===== Part 5: Iconic Events & Storylines =====
=== Secret Wars (1984) ===
During the first //Secret Wars//, Spider-Man's costume is damaged. On the advice of Thor and the Hulk, he uses a machine on Battleworld that produces a small black sphere. The sphere flows over his body, forming a new black and white costume that can respond to his thoughts, generate its own webbing, and change its appearance. This was the first appearance of a Klyntar on Earth, though its true nature as a sentient, living being was not yet known. This event is the seed from which all subsequent Symbiote stories on Earth grew.
=== Planet of the Symbiotes (1995) ===
This storyline was the first major exploration of the Symbiotes as a species. It reveals that an army of Symbiotes, drawn to Earth, sought to overwhelm the planet and bond with its population, turning it into a new hive world. The story establishes that a host's emotions can heavily influence a Symbiote, with strong negative emotions like rage and hatred making the Symbiote more powerful but also more malevolent. It culminates in Spider-Man, Eddie Brock, and Scarlet Spider working together to broadcast a psychic scream of despair that drives the invading Symbiote army to commit suicide.
=== Venom: Space Knight (2015-2016) ===
Following the cleansing of the Venom Symbiote on the planet Klyntar in //Guardians of the Galaxy//, this series follows Flash Thompson as he embraces his new role as an Agent of the Cosmos. It fully explores the Klyntar's noble culture and their mission. Flash and his now-reformed Symbiote travel the galaxy, helping those in need and fighting injustice, embodying the true potential of a perfect Klyntar-host union. This series was critical in solidifying the Klyntar retcon before the subsequent introduction of Knull.
=== King in Black (2020-2021) ===
The culmination of Donny Cates' entire //Venom// saga. Knull, finally free from his cage, arrives at Earth with an army of billions of Symbiote dragons and controlled Celestials, plunging the entire planet into a dome of living abyss. This event was a line-wide crossover that redefined the Symbiotes' place in the Marvel Universe. It revealed their true cosmic origins and power level, forcing the Avengers, X-Men, and every hero on Earth to fight a losing battle against a literal god of darkness. The event ends with Eddie Brock bonding with the Enigma Force to become Captain Universe, defeating Knull, and taking his place as the new King in Black, controller of the Symbiote Hive-Mind.
===== Part 6: Variants and Alternative Versions =====
  * **Ultimate Universe (Earth-1610):** A radical departure from the main continuity. The "Venom Suit" in this reality is not an alien but a man-made proto-organism. It was created by Richard Parker (Peter's father) and Edward Brock, Sr. (Eddie's father) as a biogenetic suit designed to cure cancer and other diseases. Peter Parker discovers the suit and wears it, but its aggressive nature proves too much for him. When Eddie Brock Jr. learns of the suit's existence and feels betrayed by Peter, he bonds with it, becoming a monstrous, cannibalistic version of Venom.
  * **Spider-Man: The Animated Series (1990s):** This influential series presented another unique origin. The Symbiote (never called a Klyntar) was brought to Earth on a space shuttle. It was portrayed as a species that needed to bond with hosts experiencing high levels of adrenaline to survive. Its relationship with Spider-Man and Eddie Brock follows the comics, but it is later revealed that the Symbiotes' home planet was destroyed by Dormammu, and Carnage attempts to bring Dormammu to Earth to feed on life energy.
  * **Marvel's Spider-Man (Video Game Series):** The Symbiote in this universe, developed by Insomniac Games, appears to be a hybrid of the 616 and Ultimate origins. It is presented as an experimental treatment for Harry Osborn's terminal genetic illness, created by his father, Norman Osborn. Contained in a tank, it keeps Harry alive symbiotically. When Peter Parker bonds with it to save his own life, it enhances his powers to incredible new levels but also amplifies his aggression, showing the classic corrupting influence. This version emphasizes its potential as both a cure and a curse.

===== Notes and Trivia =====
((The name "Klyntar" is pronounced with a silent 'K', as confirmed by writer Brian Michael Bendis.))
((The visual design of the Venom Symbiote, particularly the large white spider emblem, jagged eyes, and fanged mouth, was created by artist Todd McFarlane. The original "alien costume" design by Mike Zeck was much sleeker and featured a smaller, simpler spider emblem.))
((Before Donny Cates created Knull, the //Thor: God of Thunder// run by Jason Aaron had already established the existence of All-Black, the Necrosword, describing it as a weapon forged from the living abyss. Cates brilliantly retconned this weapon to be the very first Symbiote, seamlessly integrating his new lore into existing continuity.))
((The idea of Symbiotes having offspring (spawning) was introduced with the creation of Carnage in //The Amazing Spider-Man #361//. Symbiote reproduction is asexual, and the parent typically feels no affection for its spawn, often viewing it as a rival.))
((In the MCU, the Symbiotes are established as being vulnerable to the sound frequency of 440 Hz, which is the standard tuning note for the musical pitch of A above middle C.))
