====== Carnage (Symbiote) ======
===== Part 1: The Dossier: An At-a-Glance Summary =====
  *   **Core Identity:** **The Carnage symbiote is the chaotic, nihilistic alien offspring of the [[venom_(symbiote)|Venom symbiote]], a parasitic Klyntar entity that amplifies the homicidal urges of its hosts, most notably the serial killer [[cletus_kasady|Cletus Kasady]], to become a living engine of random slaughter and destruction.**
  *   **Key Takeaways:**
  * **Role in the Universe:** Carnage represents pure, unadulterated anarchy. Unlike its "father" Venom, who operates with a twisted moral code, the Carnage symbiote and its primary host share a singular, gleeful desire for bloodshed, making it one of the most terrifying and unpredictable threats in the [[earth-616|Marvel Universe]]. It is an aberration even among the [[klyntar]], the symbiote race.
  * **Primary Impact:** Carnage's introduction in the early 1990s dramatically escalated the level of horror and violence in [[spider-man|Spider-Man]]'s world. It forced heroes into morally gray alliances, most famously with Venom, to combat a threat that could not be reasoned with, forever changing the dynamic between Spider-Man and his symbiotic foes.
  * **Key Incarnations:** The core difference lies in their bond's origin and nature. In the Prime Comic Universe (**Earth-616**), the symbiote bonded with Cletus Kasady by merging with his bloodstream, creating a uniquely deep and permanent fusion. In Sony's Spider-Man Universe (**SSU**), the bond was formed when Kasady bit Eddie Brock and ingested a piece of the Venom symbiote, leading to a more contentious and ultimately parasitic relationship.
===== Part 2: Origin and Evolution =====
==== Publication History and Creation ====
The Carnage symbiote, inseparable from its host Cletus Kasady, crashed into the Marvel Universe in the midst of the "grim and gritty" era of 1990s comics. The character was conceived as a direct response to the immense popularity of Venom. Fans loved the dark, anti-heroic nature of Eddie Brock, so Marvel sought to create a villain who was even darker, a character with no redeeming qualities whatsoever.
The creative genesis is largely credited to writer David Michelinie and artist Mark Bagley, though artist Erik Larsen has stated he contributed to the initial concept. Michelinie wanted to create a character who was a true psychopath, a perfect match for a symbiote without the moral constraints that Eddie Brock imposed on Venom. The idea was simple but terrifying: what if the symbiote bonded with someone who was already a monster?
After a brief cameo as Cletus Kasady in //The Amazing Spider-Man// #344, the character made his full debut as Carnage in //The Amazing Spider-Man// #361 (April 1992). The design, crafted by Mark Bagley, was instantly iconic. The chaotic, sinewy red and black form, sleeker and more organic than Venom's bulky frame, visually communicated the character's insanity. The name "Carnage" itself was a direct reflection of his purpose: to cause mass destruction for its own sake. The character was an immediate hit, tapping into the era's appetite for more extreme characters and leading to the massive 1993 crossover event, //Maximum Carnage//, which cemented his status as a top-tier Marvel villain.
==== In-Universe Origin Story ====
The creation of Carnage is a tale of twisted parentage and corrupted birth, though the specifics differ significantly between the primary comic continuity and its cinematic adaptation.
=== Earth-616 (Prime Comic Universe) ===
The birth of the Carnage symbiote is a direct consequence of the volatile relationship between Eddie Brock and his Venom symbiote. While incarcerated at Ryker's Island Prison, Brock shared a cell with the notorious serial killer, Cletus Kasady. Kasady, a diagnosed psychopath with a nihilistic worldview, had a history of horrific crimes, including pushing his grandmother down a flight of stairs and torturing his mother's dog.
Brock's "other," the Venom symbiote, eventually tracked him down and staged a dramatic prison break. As the symbiote tore through the prison walls to rebond with Eddie, it underwent a form of asexual reproduction, leaving behind a nascent offspring in the cell. This is a rare, though not unheard of, occurrence for the Klyntar species, often triggered by extreme stress or the desire to propagate.
The newborn symbiote, alone and without a host, found one in the remaining occupant of the cell: Cletus Kasady. As Kasady ranted about the beauty of chaos, the symbiote slithered towards him. It entered his body through a small cut on his hand, bonding with him not just superficially, but on a cellular level by merging directly with his bloodstream. This unique method of bonding created a fusion far deeper and more stable than the one between Eddie Brock and Venom. Cletus Kasady and the symbiote didn't just share a body; they became a singular entity, referring to themselves as "I" far more often than "we."
This blood-based bond made "Carnage," as Kasady named his new persona, exponentially more powerful than its progenitor. The symbiote amplified Kasady's already monstrous psyche, and in turn, Kasady's unending bloodlust fed the symbiote's primal instincts. Together, they embarked on a killing spree based on the "philosophy" that life was meaningless and the ultimate freedom was random, chaotic murder. This origin story established Carnage not merely as another villain, but as a living embodiment of nihilistic horror.
=== Marvel Cinematic Universe (MCU) / Sony's Spider-Man Universe (SSU) ===
The cinematic origin of Carnage is depicted in the 2021 film //Venom: Let There Be Carnage//, which takes place in Sony's Spider-Man Universe (SSU), a separate continuity from the mainstream Marvel Cinematic Universe (MCU).((While Sony and Marvel Studios have a partnership allowing Spider-Man to appear in the MCU, films like //Venom//, //Morbius//, and //Madame Web// exist in their own distinct SSU continuity. Crossovers, like the post-credit scene in //Spider-Man: No Way Home//, are the exception.))
In this version, Cletus Kasady (played by Woody Harrelson) is a death row inmate at San Quentin Prison, a notorious serial killer who agrees to grant an exclusive final interview to journalist Eddie Brock (Tom Hardy). During a heated confrontation, an agitated Kasady provokes Brock and bites his hand. In doing so, Kasady ingests a small amount of Brock's blood, which is infused with the genetic material of the Venom symbiote.
This act serves as the catalyst for the new symbiote's creation. The ingested symbiote particles gestate within Kasady, feeding on his rage and dark nature. The symbiote fully manifests during Kasady's execution by lethal injection. The chemicals fail to kill him; instead, they trigger a violent transformation. The red symbiote bursts forth, slaughtering the prison guards and freeing Kasady.
This newly-formed Carnage symbiote is immediately more violent and powerful than Venom. It shares Kasady's twisted love for his childhood sweetheart, Frances Barrison (Shriek), and works with him to unleash a wave of destruction.
The key differences from the comics are significant. The cinematic origin is more direct and less accidental; it is an act of aggression (a bite) that creates Carnage. Furthermore, the bond is portrayed as more parasitic and contentious. The Carnage symbiote has its own distinct personality and at times disagrees with Kasady, particularly regarding Shriek, whose sonic powers are a fatal weakness. This culminates in their separation and defeat, a stark contrast to the near-perfect synthesis of the Earth-616 version.
===== Part 3: In-Depth Analysis: Powers, Abilities, and Weaknesses =====
The Carnage symbiote is a biological weapon of immense power, consistently demonstrating capabilities that surpass those of its progenitor, Venom. Its unique bond with Cletus Kasady and its inherently more psychotic nature make it a top-tier threat.
=== Earth-616 (Prime Comic Universe) ===
The bond between Kasady and the symbiote is so profound that the symbiote's biomass is integrated into his very blood. This makes their separation nearly impossible and grants Carnage a host of terrifying abilities.
  *   **Superhuman Physiology:**
  * **Strength:** Carnage's strength is immense, far exceeding that of Spider-Man and, in most encounters, Venom. He can lift well over 80 tons and has been shown overpowering multiple heroes at once.
  * **Durability:** The symbiote's biomass can act as a highly effective armor, capable of withstanding high-caliber bullets, explosions, and tremendous impact forces with no damage.
  * **Speed & Agility:** Carnage is deceptively fast and agile, capable of moving at speeds that can overwhelm even Spider-Man's enhanced reflexes.
  * **Regenerative Healing Factor:** Like all symbiotes, it possesses a powerful healing factor. However, because it's bonded to Kasady's bloodstream, it can regenerate from seemingly fatal wounds, such as decapitation or being torn in half, as long as a single cell remains.
  *   **Offensive Capabilities:**
  * **Shapeshifting & Weapon Manifestation:** This is Carnage's signature ability and his preferred method of killing. He can morph his limbs into a horrifying arsenal of solid constructs, including axes, scythes, swords, spears, and complex bladed weapons. Unlike Venom, who typically forms simple tendrils or mouths, Carnage's constructs are intricate and deadly. He can also detach these portions of himself as projectiles, such as razor-sharp darts or spikes.
  * **Constituent-Matter Manipulation:** Carnage can manipulate the symbiote's biomass at a molecular level, allowing him to become liquid-like to flow through small spaces or expand his body to a massive size.
  * **Webbing:** Like Venom, Carnage can produce a form of organic "webbing" from its biomass, allowing for travel and ensnaring victims. This webbing is often depicted as red and black and is exceptionally strong.
  * **Symbiote Infection:** In some storylines, particularly //Carnage U.S.A.//, he demonstrated the ability to extend his symbiote to infect and control the nervous systems of hundreds of people simultaneously, effectively creating a hive-mind with himself at the center.
  *   **Inherent Symbiote Abilities:**
  * **Wall-Crawling:** Inherited from the genetic memory of Spider-Man within the Venom symbiote, Carnage can cling to virtually any surface.
  * **Immunity to Spider-Sense:** As an offspring of Venom, Carnage does not trigger Spider-Man's precognitive danger sense, making him an exceptionally dangerous and unpredictable opponent in a fight.
  * **360-Degree Sense:** The symbiote itself acts as a sensory organ, allowing Carnage to perceive threats from all directions.
  * **Camouflage:** It can alter its appearance to perfectly mimic other clothing or blend into its surroundings.
  *   **Weaknesses:**
  * **Sonic Frequencies:** The most well-known weakness of the Klyntar race. High-frequency sounds can cause the symbiote physical pain and force it to separate from its host. However, over time, Carnage has developed a higher tolerance to sonics than Venom.
  * **Intense Heat:** Fire and extreme heat are also highly effective at damaging the symbiote's biomass and can be lethal in sufficient quantities.
  * **Anti-Venom:** The touch of the [[anti-venom|Anti-Venom symbiote]], a curative entity created from remnants of the Venom symbiote in Eddie Brock's body, is caustic to Carnage. Its touch is like a powerful acid that can dissolve the symbiote.
  * **Connection to Knull:** After the rise of [[knull|Knull, the Symbiote God]], Carnage became susceptible to his control. As a powerful but lesser symbiote, it could be dominated by Knull's will, overriding Kasady's own.
=== Marvel Cinematic Universe (MCU) / Sony's Spider-Man Universe (SSU) ===
The cinematic Carnage is a powerhouse, though its abilities are presented in a slightly more straightforward manner.
  *   **Powers & Abilities:**
  * **Superhuman Strength & Durability:** Similar to its comic counterpart, the SSU Carnage is demonstrably stronger than Venom, able to easily overpower him in their initial confrontations. It can withstand police gunfire without flinching.
  * **Extreme Shapeshifting:** This is its primary visual feature. The SSU Carnage is a whirlwind of tendrils, blades, and spikes. It can create multiple limbs, form massive scythes, and even turn into a destructive cyclone of red and black biomass, earning it the moniker "the red one."
  * **Projectile Attacks:** It can launch sharp tendrils from its body as deadly projectiles.
  * **Technological Interface:** In a unique cinematic ability, Carnage demonstrated the power to interface with computer systems, using its tendrils to hack into the internet to locate information on Frances Barrison.
  *   **Weaknesses:**
  * **Sonic Frequencies (Extreme Vulnerability):** The film emphasizes this weakness even more than the comics. High-frequency sounds are agonizing to Carnage. The sonic scream of the mutant Shriek is particularly devastating, causing the symbiote to physically recoil and separate from Kasady. This incompatibility is a central plot point and the key to its defeat.
  * **Fire:** Fire is also established as a critical weakness, used by Eddie Brock and Venom to wound Carnage during their final battle.
  * **Host/Symbiote Incompatibility:** Unlike the perfect union in the comics, the SSU Carnage and Cletus Kasady are not a true symbiotic match. The symbiote has its own desires (e.g., self-preservation) and ultimately betrays Kasady when it sees a more suitable host in Eddie Brock, whom it recognizes as a perfect match for a symbiote. This lack of a perfect bond is its ultimate downfall, as Venom is able to exploit this division to separate and consume it.
===== Part 4: Key Relationships & Hosts =====
While inextricably linked to Cletus Kasady, the Carnage symbiote has a history of bonding with others, spreading its influence and chaos across the universe.
==== Primary Host: Cletus Kasady ====
The relationship between the symbiote and Cletus Kasady is the core of Carnage's identity. It's less a partnership and more a perfect, horrifying synthesis. Cletus was a monster long before the symbiote. He believes in no rules, no laws, only the freedom of chaos, which he expresses through murder. The symbiote, a newborn alien parasite with no moral compass, found in Kasady's mind the perfect expression of its own primal urges. It doesn't just enable Kasady; it //celebrates// him. Their bond is one of mutual adoration, with both halves driving each other to greater acts of depravity. This makes Carnage one of the few villains who genuinely loves what he is.
==== Other Notable Hosts ====
  *   **Ben Reilly (Spider-Carnage):** During the Clone Saga, the symbiote briefly abandoned a weakened Kasady and bonded with Ben Reilly, the clone of Peter Parker. As //Spider-Carnage//, Ben's heroic will was constantly at war with the symbiote's bloodlust. It was a torturous experience that showed even a hero's mind could barely contain the symbiote's influence.
  *   **Silver Surfer (Carnage Cosmic):** In one of its most powerful incarnations, the symbiote bonded with the Silver Surfer, Norrin Radd. The fusion, dubbed //Carnage Cosmic//, possessed the Power Cosmic, making it a universe-level threat capable of destroying planets. It took Spider-Man's intervention and an appeal to the Surfer's buried conscience to force their separation.
  *   **Norman Osborn (Red Goblin):** In a terrifying modern storyline, the symbiote was forcibly bonded to a captured Norman Osborn, the Green Goblin. Osborn, already insane, was able to dominate the symbiote's will with his own. Merging the symbiote's power with the Goblin Formula and an arsenal of Goblin tech (like "Carnage-Bombs"), he became the //Red Goblin//, a villain who knew all of Spider-Man's secrets and possessed the power to finally kill him.
==== Progenitor and Progeny ====
  *   **Venom (Progenitor):** Carnage harbors an intense, patricidal hatred for Venom. It views its "father" as weak and pathetic for clinging to a twisted moral code and for its symbiotic relationship with humans. Venom, in turn, sees Carnage as a mistake, a cancerous offspring that it feels a responsibility to destroy. Their battles are among the most brutal in Marvel Comics.
  *   **Toxin (Progeny):** The Carnage symbiote also reproduced, giving birth to its own offspring. Horrified by the idea of creating a rival and disgusted by the concept of family, Carnage attempted to kill its spawn immediately. This new symbiote, the 1,000th in their genetic line, bonded with police officer Patrick Mulligan. Named //Toxin// by Venom, this new being had the potential to be a hero, representing everything Carnage despised.
==== Arch-Enemies ====
  *   **Spider-Man:** Peter Parker is Carnage's ultimate ideological opposite. Spider-Man represents order, responsibility, and the sanctity of life. Carnage represents chaos, nihilism, and the glee of murder. Carnage delights in tormenting Spider-Man, not just physically, but psychologically, forcing him to confront a level of pure evil that challenges his core beliefs.
  *   **Venom:** Their conflict is both personal and philosophical. It's the "son" trying to usurp and destroy the "father." For much of their history, Venom has been forced into the role of a reluctant hero, understanding that he is one of the only beings with the power and ruthlessness required to stop Carnage's rampages.
===== Part 5: Iconic Events & Storylines =====
Over the decades, Carnage has been the central figure in several major, city-spanning events that have left a bloody mark on the Marvel Universe.
==== Maximum Carnage (1993) ====
This 14-part crossover is the definitive Carnage story. After escaping from the Ravencroft Institute, Carnage recruits a "family" of psychotic supervillains, including Shriek, Doppelganger, Carrion, and Demogoblin. Together, they cut a bloody swath across New York City, murdering indiscriminately to spread their message of chaos. The scale of the violence was unprecedented, forcing a desperate Spider-Man to forge an uneasy alliance with Venom. He also assembled a small army of other heroes and anti-heroes, including Captain America, Black Cat, Cloak & Dagger, and Morbius, to put an end to the massacre. The event explored themes of moral compromise and questioned whether lethal force was necessary to stop a monster like Carnage, solidifying his reputation as an A-list threat.
==== Carnage U.S.A. (2011) ====
This miniseries took Carnage's threat to a new level of body horror. The symbiote traveled to Doverton, Colorado, and in a terrifying display of power, infected the town's entire population by extending its biomass through the water and meat-packing plant supply. He took control of not only the citizens but also a captive team of Avengers (Captain America, Hawkeye, The Thing, and Wolverine), creating twisted "Carnage" versions of them. The story required a specialized team, including Spider-Man and Agent Venom (Flash Thompson), to enter the quarantined town and fight an entire army controlled by a single, malevolent will.
==== Absolute Carnage (2019) ====
This epic event served as the culmination of decades of symbiote lore. Cletus Kasady, resurrected by a cult worshipping the dark god Knull, was bonded to a new, more powerful version of the Carnage symbiote that had been augmented by Knull's power. His new mission was to hunt down every single person on Earth who had ever bonded with a symbiote—hero or villain. By ripping out their spines, he could harvest the genetic "codex" left behind by the symbiotes. His goal was to collect enough codices to free Knull from his cosmic prison. This event elevated Carnage from a street-level horror to a cosmic-level threat, forcing the entire Marvel Universe, from the Avengers to the X-Men, to unite against his god-fueled rampage.
===== Part 6: Variants and Alternative Versions =====
  *   **Ultimate Universe (Earth-1610):** The Ultimate version of Carnage was radically different. It was not an alien but a bio-engineered vampiric organism created by Dr. Curt Connors (The Lizard). Using a combination of his own DNA, Peter Parker's DNA, and genetic material from the Venom "suit," he created a self-regenerating organism that lacked a stable consciousness. It first "bonded" with Gwen Stacy, consuming her before being defeated by Spider-Man. This version was a mindless, life-draining monster rather than a sentient, philosophical killer.
  *   **Spider-Man: The Animated Series (1990s):** This popular adaptation introduced Carnage to a mainstream audience. The origin was largely faithful to the comics, with Cletus Kasady gaining the symbiote in prison. However, to comply with broadcast standards, his backstory as a serial killer was toned down to him being a dangerous, insane criminal. He was a recurring threat who, in the series finale, was chosen by the demonic Dormammu and Baron Mordo to serve as an anchor to travel dimensions, leading to the creation of the powerful and tragic reality-hopping villain, //Spider-Carnage//.
  *   **Video Games:** Carnage's popularity was cemented by his role as the final boss in the 1994 Super NES and Sega Genesis beat 'em up, //Spider-Man and Venom: Maximum Carnage//. This game, notable for its red cartridge, adapted the famous comic storyline and was a massive hit. More recently, Cletus Kasady and his "Carnage Cult" appeared as the antagonists of "The Flame" side-mission in the 2023 video game //Marvel's Spider-Man 2//, ending with Kasady stealing a symbiote sample and setting up the full arrival of Carnage in a future installment.

===== Notes and Trivia =====
((The name "Carnage" was chosen after Marvel's legal department rejected the first choice, "Chaos," and the second choice, "Ravage." //Amazing Spider-Man// #361.))
((Co-creator Mark Bagley initially designed Carnage to have no black coloration, wanting the character to be purely, vividly red to reflect his connection to blood. The black, chaotic swirls were added by the inker, Randy Emberlin, to give the character more depth and visual texture, creating the iconic design known today.))
((In the comics, the Carnage symbiote is technically genderless, but is often referred to with male pronouns due to its deep bond with the male host, Cletus Kasady.))
((The concept of a symbiote's offspring being stronger than the parent is a consistent theme in Marvel Comics. Carnage is more powerful than Venom, and Carnage's own offspring, Toxin, was in turn stronger than both of them combined.))
((While Carnage is most famous for his battles with Spider-Man and Venom, he has also had significant confrontations with other heroes, including Deadpool in the miniseries //Deadpool vs. Carnage// and the Scarlet Witch, who used chaos magic to briefly invert his psyche during the //AXIS// event.))
((The cinematic distinction between the MCU and the SSU is a point of frequent fan discussion. As of 2024, the only character to fully cross from the SSU into the MCU and back was Eddie Brock/Venom in the post-credits scenes of //Venom: Let There Be Carnage// and //Spider-Man: No Way Home//, though he left a piece of the symbiote behind in the MCU.))
((The //Absolute Carnage// event revealed that the Grendel symbiote dragon controlled by Knull was considered the "original" Carnage, with the red symbiote bonded to Cletus being an offshoot that resonated with the Grendel's chaotic energy.))
((Cletus Kasady's philosophy is a form of radical nihilism. He believes that laws and morality are illusions and that the only "truth" is chaos and death, a worldview the symbiote wholeheartedly embraces.))
