The Serpent (Cul Borson)

  • Core Identity: The Serpent, whose true name is Cul Borson, is the long-imprisoned elder brother of Odin and the ancient Asgardian God of Fear, who feeds on and manipulates the terror of mortals to achieve ultimate power.
  • Key Takeaways:
  • Role in the Universe: The Serpent serves as the primary antagonist of the 2011 Marvel Comics crossover event, fear_itself. He is a primordial force of cosmic terror, believing that fear, not honor or hope, is the true ruling principle of the universe. His re-emergence was foretold in an ancient Asgardian prophecy that predicted he would be slain by Thor, but only at the cost of Thor's own life.
  • Primary Impact: His brief but cataclysmic return to Earth-616 resulted in global devastation, the temporary deaths of both Bucky Barnes (as Captain America) and thor, and the iconic shattering of Captain America's vibranium-adamantium alloy shield. He empowered a select group of superhumans, transforming them into his avatars of destruction known as the_worthy.
  • Key Incarnations: The Serpent is an entity exclusive to the Earth-616 comic book continuity and has no direct counterpart in the Marvel Cinematic Universe (MCU). However, his character concept—a powerful, long-lost elder sibling of Thor, imprisoned by Odin, whose return threatens Asgard's very existence—shares significant thematic parallels with the MCU's version of Hela Odinsdottir in the film Ragnarok.

The Serpent first appeared in a shadowy cameo in the prologue comic Fear Itself: Book of the Skull #1 (April 2011) before making his full debut in Fear Itself #1 (June 2011). He was co-created by writer Matt Fraction and artist Stuart Immonen as the central villain for Marvel's major summer crossover event of that year. The creation of The Serpent occurred during a period when Marvel Comics was heavily focused on large-scale, line-wide events that promised to change the status quo of the universe. Coming after events like Civil War, Secret Invasion, and Siege, Fear Itself was designed to tap into the real-world anxieties of a post-recession era, exploring themes of widespread panic, mistrust, and hopelessness. The Serpent was conceived as the literal embodiment of this zeitgeist. His design by Immonen is notably regal yet menacing, often depicted in aged Asgardian armor and a horned helmet, visually positioning him as a dark mirror to his brother, Odin. His narrative function was to create a threat so overwhelming that it would force heroes like Captain America, Thor, and Iron Man to confront their deepest fears and make ultimate sacrifices.

In-Universe Origin Story

Earth-616 (Prime Comic Universe)

The Serpent's origins are rooted in the dawn of Asgardian history, a time of myth and conquest largely erased from official records by his younger brother, Odin Borson. Cul Borson was the firstborn of Bor, the king of Asgard, and was destined to inherit the throne. However, where Odin came to value honor, wisdom, and protection, Cul embraced fear as the ultimate tool of governance. He believed that to rule was to be feared, and he reveled in the terror he inspired, drawing strength from it. His reign was brutal and tyrannical. He was a conqueror who spread his dark influence across the Ten Realms. During this ancient time, Cul had his own court of loyal followers, a precursor to the Worthy he would later create. His philosophy clashed violently with that of Odin, who saw his brother's path leading only to nihilism and destruction. This ideological schism erupted into a cataclysmic civil war that tore Asgard apart. Odin, wielding his immense power, ultimately defeated his elder brother. Rather than kill Cul, which may have been impossible or would have created a martyr, Odin chose to imprison him. He sealed The Serpent in the deepest, most lightless part of the ocean on Midgard (Earth)—the Marianas Trench. To ensure his prison would never be breached, Odin placed his own life force as a lock and then systematically purged almost all knowledge of his brother from Asgard's history and memory. He left behind only a single, dire prophecy: if The Serpent ever returned, it would signal the end of Asgard and would require the death of Odin's favorite son, thor, to stop him. For millennia, Cul slumbered in his watery tomb, his existence a forgotten secret, while Odin ruled Asgard and built a legacy founded on the very principles his brother despised. His reawakening was set in motion by Sin, the daughter of the red_skull, who was guided by her father's arcane texts. Using the Book of the Skull, Sin located a mystical hammer in Antarctica. Upon lifting it, she was transformed into Skadi, the Herald of the Serpent, and the psychic shockwave of her transformation shattered Cul's prison. Freed at last, The Serpent immediately began his campaign to reclaim his throne and plunge the universe into a new age of terror.

Marvel Cinematic Universe (MCU)

The Serpent, as the specific character Cul Borson, does not exist and has never appeared or been mentioned in the Marvel Cinematic Universe. The primary antagonist sharing a similar familial role is Hela Odinsdottir, who served as the main villain in the 2017 film Thor: Ragnarok. The narrative parallels between Cul and Hela are striking and suggest that Hela's cinematic story may have been influenced by the themes introduced in the Fear Itself comic storyline. A comparative analysis highlights these similarities:

  • The Long-Lost Elder Sibling: Both Cul and Hela are the firstborn children of their respective fathers (Bor and Odin) and were the original heirs to the throne of Asgard. Both represent a darker, more violent chapter of Asgard's history that Odin actively suppressed and erased from public knowledge.
  • Imprisonment by Odin: Both characters were deemed too dangerous and uncontrollable by Odin. Cul was sealed at the bottom of the ocean, while Hela was banished to the dimension of Hel. In both cases, Odin's own life force was the key to their imprisonment; their freedom was only granted upon his death.
  • A More Brutal Philosophy: Both characters espouse a philosophy of conquest and domination that clashes with the more “enlightened” Asgard that Thor knows. Cul believes in rule through fear, while Hela believes in rule through imperial might and bloodshed, viewing modern Asgard as soft and weak.
  • Prophesied Doom: The return of both characters is linked to a prophecy of doom for Asgard. Cul's return triggers the prophecy of Ragnarok where Thor must die to defeat him, while Hela's return directly causes the events of Ragnarok, leading to the physical destruction of Asgard's planetary body.
  • Source of Power: While their power sets differ, the source is thematically linked to their domain. The Serpent draws power from the fear of others, growing stronger as global panic spreads. Hela draws her power directly from the realm of Asgard itself, becoming seemingly invincible while she is physically present there.

The decision to use Hela instead of The Serpent in the MCU was likely driven by several factors. Hela is a more established and classic Thor villain from the comics (created by Stan Lee and Jack Kirby in 1964), making her a more recognizable choice. Furthermore, her story as Odin's executioner tied more cleanly into the MCU's established lore and the specific themes of colonial legacy and historical revisionism that director Taika Waititi explored in Thor: Ragnarok.

Earth-616 (Prime Comic Universe)

The Serpent is an Elder God of Asgard, possessing power that rivals, and in some aspects surpasses, that of Odin himself, particularly when he is fueled by fear.

  • Asgardian Physiology: As the firstborn of Bor, Cul possesses superhuman physical attributes far exceeding those of a typical Asgardian.
    • `Superhuman Strength:` His strength is in the Class 100+ range, sufficient to engage Odin in direct physical combat. At the height of his power during Fear Itself, he effortlessly shattered Captain America's shield with his bare hands, a feat previously thought impossible.
    • `Superhuman Durability:` He is virtually invulnerable to most forms of physical and energy-based harm. He withstood direct attacks from the Avengers and even a blast from Odin's spear, Gungnir.
    • `Superhuman Stamina & Healing:` He can exert himself at peak capacity for extended periods and possesses a powerful regenerative healing factor.
    • `Longevity:` Like all Asgardians, he is extremely long-lived, having been imprisoned for millennia without aging.
  • God of Fear: This is his primary and most defining power.
    • `Fear Empowerment:` The Serpent literally consumes fear. The more terror, panic, and despair that exists in the sentient beings around him, the more powerful he becomes. During his global assault, the worldwide panic amplified his abilities to a cosmic scale.
    • `Fear Manipulation:` He can project and instill intense fear in others, paralyzing heroes and causing mass hysteria in entire populations. He can manifest an individual's worst fears as psychic illusions.
  • Dark Magic (Asgardian Sorcery): Cul is a master of powerful, ancient forms of Asgardian magic, often dark and corrupting in nature.
    • `Shapeshifting:` He can alter his form at will. His most formidable transformation was into a colossal, world-ending serpent, a nod to the mythological Jörmungandr, the Midgard Serpent.
    • `Energy Projection:` He can fire powerful blasts of dark energy.
    • `Matter Manipulation:` He was able to raise his “Dark Asgard” citadel from the ground in Antarctica and terraform the surrounding area.
  • Creation of The Worthy: One of his most devastating abilities was the power to create mystical Uru hammers, similar to Thor's Mjolnir but imbued with his own dark essence. These hammers sought out individuals with deep-seated fear, rage, or doubt and transformed them into his avatars, the Worthy, granting them immense power and corrupting their minds.
  • The Hammers of the Worthy: These seven enchanted hammers were his primary weapons, used to sow chaos across the globe by empowering his chosen champions.

^ Hammer Name ^ Wielder ^ Title ^

Hammer of Skadi Sin (Sinthea Schmidt) Skadi, Breaker of Worlds
Hammer of Kuurth Juggernaut (Cain Marko) Kuurth, Breaker of Stone
Hammer of Nul Hulk (Bruce Banner) Nul, Breaker of Worlds
Hammer of Skirn Titania (Mary MacPherran) Skirn, Breaker of Men
Hammer of Nerkkod Attuma Nerkkod, Breaker of Oceans
Hammer of Mokk Grey Gargoyle (Paul Duval) Mokk, Breaker of Faith
Hammer of Angrir The Thing (Ben Grimm) Angrir, Breaker of Souls

Cul's personality is defined by an absolute and unwavering belief in his own philosophy. He is arrogant, cruel, and dismissive of all other forms of power, particularly the concepts of hope, love, and honor championed by Odin and Thor. He views these as weaknesses, lies told by a weaker brother to control the masses. He is a nihilist at his core; when faced with defeat, his goal shifted from ruling the world to simply burning it to ash out of spite. He has a deep-seated hatred and jealousy for Odin, not just for imprisoning him, but for successfully supplanting his legacy with a “weaker” ideology that proved more enduring. He is utterly without empathy, viewing mortals as little more than batteries for his power, their fear being the only thing that gives their existence meaning.

Marvel Cinematic Universe (MCU)

As The Serpent does not exist in the MCU, this section analyzes the attributes of his thematic counterpart, Hela.

  • Powers and Abilities:
    • `Asgardian Physiology:` As Odin's firstborn, Hela possessed immense strength, durability, and speed, allowing her to single-handedly destroy the entire army of Asgard and crush Thor's hammer, Mjolnir, with one hand.
    • `Asgardian Empowerment:` Hela's primary power was her symbiotic connection to the realm of Asgard. The longer she was there, the more powerful she became, making her seemingly invincible on her home turf. This is the cinematic parallel to Cul's fear empowerment—both villains have a unique source that makes them grow stronger over the course of the conflict.
    • `Necro-Weapons:` Hela could manifest various weapons, primarily swords and daggers, out of her own body and the environment of Asgard. This ability was near-limitless, allowing her to overwhelm opponents with a barrage of deadly projectiles.
    • `Control over the Undead:` She could resurrect her ancient Berserker army and her giant wolf, Fenris, from their tombs beneath Asgard's palace.
  • Personality: Like Cul, Hela is arrogant, power-hungry, and utterly ruthless. She holds a deep-seated grudge against Odin for imprisoning her and erasing her from history after she had helped him conquer the Nine Realms. She sees Thor's reign and Odin's later philosophy as a weak and hypocritical betrayal of Asgard's true, bloody nature. She believes in power and conquest above all else and shows no remorse for her actions, viewing her violent campaign as simply reclaiming her birthright. This mirrors Cul's belief that his rule of fear is the “true” way of the universe.

The Serpent does not have allies in the traditional sense; he has servants and tools. His primary agents were the_worthy, the eight individuals empowered by his dark hammers.

  • Skadi (Sin): As the one who freed him, Sin held a special place as his primary herald. Her fanatical devotion, inherited from her father the Red Skull, made her the perfect vessel for his will. She acted as his field commander and was the most loyal and ideologically aligned of all the Worthy.
  • Nul, Breaker of Worlds (The Hulk): This transformation was perhaps the most dangerous. The hammer amplified the Hulk's already limitless rage and resentment, turning him into a purely destructive force completely unburdened by Bruce Banner's conscience. His rampage across the globe required the intervention of a cosmically-empowered Thor.
  • Angrir, Breaker of Souls (The Thing): Ben Grimm's transformation was the most tragic. The hammer preyed on his deep-seated despair and insecurity over his monstrous form, turning the heroic “ever-lovin' blue-eyed Thing” into a being of pure rage who nearly killed his own teammates in the Future Foundation and the Avengers. His eventual breaking of the curse was a major turning point in the war.
  • Odin: The Serpent's ultimate nemesis is his younger brother. Their conflict is the central family drama of Fear Itself. It is a deeply personal and philosophical war that has simmered for eons. Odin represents order, sacrifice, and the protection of the lesser realms, while Cul represents chaos, tyranny, and the divine right to rule through terror. Odin's decision to imprison Cul and hide the truth defined Asgard's modern history, and Cul's return is the ultimate consequence of that ancient choice.
  • Thor: As Odin's champion and son, Thor is the physical embodiment of everything Cul despises. He is the prophesied hero destined to stop The Serpent. Their conflict is one of brute force and ideology—Thor's heroism and self-sacrifice against Cul's nihilistic terror. Their final battle, where Thor is armed with the Odin-Sword and clad in Uru armor, is a clash of gods that decides the fate of Earth, ultimately fulfilling the prophecy that they would kill one another.
  • Captain America (Steve Rogers): While not a cosmic powerhouse, Captain America represents the indomitable spirit of humanity that directly challenges The Serpent's philosophy. The Serpent believes humanity is weak and meant to be ruled by fear. Captain America's unwavering courage, even in the face of overwhelming despair, is a symbolic and literal rebuke to Cul's power. This is why The Serpent shattering his shield was such a devastating symbolic blow—it was an attempt to break the spirit of hope itself.
  • Gods of Asgard: By birthright, Cul is an Asgardian god and a member of its royal family. However, he is an outcast and enemy to the modern pantheon, who view him as an ancient evil.
  • The Worthy: This was the name given to his empowered champions. They were his “court,” his generals, and the primary instruments of his global terror campaign. They had no formal structure beyond serving his will.

The Serpent's entire existence in the Marvel Universe is almost exclusively defined by a single, massive storyline.

  • Premise: Following the events of Siege, the heroes of Earth are enjoying a period of relative peace. This is shattered when Sin, daughter of the Red Skull, discovers the Hammer of Skadi and frees her master, The Serpent, from his undersea prison. The Serpent then unleashes seven more hammers across the globe, which transform some of Earth's most powerful heroes and villains into his mind-controlled avatars, the Worthy. Their mission: to spread fear on a global scale, empowering The Serpent for his final conquest.
  • The Serpent's Arc: Upon his release, Cul establishes a dark, otherworldly citadel in Antarctica. He addresses the world via broadcast, declaring his intention to rule through fear. As the Worthy rampage, causing mass destruction and panic, Cul's power grows exponentially. The Avengers' initial attempts to fight the Worthy prove futile, as they are both physically and psychologically outmatched. The conflict escalates when Odin, initially intending to abandon and burn Earth to stop his brother, is convinced by Thor to help. Odin provides the heroes with Uru-enchanted weapons, and Thor prepares for his prophesied final battle. The Serpent marches on Broxton, Oklahoma (the site of Asgard on Earth at the time), and in a final gambit, transforms into a monstrous serpent to devour the world.
  • Critical Decisions & Consequences:
    • `Empowering the Worthy:` The Serpent's choice of avatars was strategic, targeting individuals with immense power (Hulk, Juggernaut) and symbolic importance (The Thing) to maximize both physical damage and psychological terror.
    • `Shattering the Shield:` By breaking Captain America's shield, The Serpent delivered a crippling blow to the morale of both the heroes and the public, cementing the idea that hope was lost.
    • `The Final Battle:` Ultimately, The Serpent was defeated when Thor, armed with Ragnarok (the Odinsword), struck him down. However, the prophecy was fulfilled as The Serpent dealt Thor a fatal blow in his final moments. The Serpent's body turned to dust, and his death ended the influence over the Worthy, but the cost was immense. Thor was dead, Asgard was in ruins, and the world was left to pick up the pieces, leading into the “Shattered Heroes” era.

As a relatively recent character created for a specific, self-contained event, The Serpent has not had the opportunity to appear in numerous alternate realities or adaptations in the same way as classic villains like Doctor Doom or Magneto.

  • Secret Wars (2015): While Cul himself did not play a major role in the main Secret Wars event, the concept of his Hammers of the Worthy reappeared. In the Battleworld domain known as Greenland, a version of the Hulk who had become a warlord known as the Maestro was seen to have a collection of artifacts from slain heroes and villains, which included several of the hammers of the Worthy.
  • Video Game Adaptations: The Fear Itself storyline and The Serpent's Worthy have been adapted in several Marvel video games.
    • In the Facebook game Marvel: Avengers Alliance, Fear Itself was a major “Special Operations” event, where players could recruit heroes and fight against all of the Worthy, with The Serpent as the final boss.
    • The mobile game Marvel Strike Force also features Sin as a playable character, with her abilities and costume heavily referencing her time as Skadi.

The lack of prominent variants underscores The Serpent's role as a singular, event-specific threat. His story is intrinsically tied to the Fear Itself prophecy and his relationship with the prime Earth-616 versions of Odin and Thor, making him difficult to transplant into other realities without his core narrative context.


1)
The Serpent's backstory and his final battle with Thor are heavily inspired by the figures of Jörmungandr (the Midgard Serpent) and Fenrir from Norse mythology. In the myths, the serpent is a child of Loki and is prophesied to be slain by Thor during Ragnarök, though Thor will also die from its venom.
2)
Cul's full name, Cul Borson, establishes him as the son of Bor, and thus the elder brother of Odin. This retcon added a new layer to Odin's family history, which previously only listed his known brothers as Vili and Ve.
3)
The Uru metal used to create the Hammers of the Worthy was mystically enchanted by The Serpent, but it is the same base metal used by the dwarves of Nidavellir to forge Mjolnir and other Asgardian weapons.
4)
Following The Serpent's defeat, Tony Stark collected the Uru from the Worthy's hammers and, with the help of the dwarves of Svartalfheim, forged new weapons and armor for the Avengers, known as the “Asgardian-tech” suits.
5)
Despite being killed by Thor, The Serpent's essence, as the embodiment of fear, is implied to be eternal. It was later suggested that his spirit could one day reform if fear once again gripped the universe on a cosmic scale.

The Serpent's initial full appearance was in Fear Itself #1 (June 2011), by Matt Fraction and Stuart Immonen.
