Thulsa Doom

• Core Identity: Thulsa Doom is an ancient and supremely powerful undead sorcerer, a pre-human king from the Thurian Age who became the immortal leader of the malevolent Serpent Men and their death cults, most famously clashing with both Kull the Conqueror and Conan the Barbarian.
• Key Takeaways:
• Role in the Universe: He is an archetypal dark wizard and cult leader, representing a primordial evil that predates modern humanity. Thulsa Doom is a master manipulator whose influence, primarily through the Cult of Set, has festered for millennia, serving as a recurring antagonist in Marvel's sword-and-sorcery sagas.
• Primary Impact: His most significant impact lies in defining the magical and cosmic threats of Robert E. Howard's Hyborian Age within the Marvel Universe. He serves as the ultimate nemesis for both Kull and Conan, establishing a benchmark for mystical villainy that is both personal (through direct conflict) and epic (through his vast, ancient conspiracies).
• Key Incarnations: The prime comic version (Earth-616) is a skeletal-faced lich-sorcerer, an ancient enemy of King Kull who survived into Conan's era. Critically, Thulsa Doom has never appeared in the Marvel Cinematic Universe (MCU); his most famous adaptation in other media is the 1982 film Conan the Barbarian, which presents a significantly different version that has heavily influenced public perception of the character.

Thulsa Doom's history is unique, as he predates his Marvel Comics debut by several decades. The character was originally created by writer Robert E. Howard, the visionary author behind Conan and Kull, for a Kull story titled “The Cat and the Skull,” which was not published in Howard's lifetime. His first public appearance was in a 1967 paperback collection titled King Kull. His introduction into the Marvel Universe came when Marvel Comics began adapting Howard's works. Thulsa Doom made his first Marvel Comics appearance in Kull the Conqueror #3 (September 1971), in a story titled “The Skull of Silence,” written by the legendary Roy Thomas and drawn by Marie Severin and John Severin. Thomas, a key architect of Marvel's expansion into sword-and-sorcery, faithfully adapted Doom from Howard's original concept, establishing him as Kull's arch-nemesis from the pre-cataclysmic Thurian Age. Later, as the popularity of Conan the Barbarian comics soared, Roy Thomas ingeniously wove Thulsa Doom into Conan's timeline. He first appeared in a Conan title in Conan the Barbarian #25 (April 1973), establishing that the ancient sorcerer had survived the fall of Atlantis and the Thurian Age to become a persistent threat in Conan's Hyborian Age. This decision cemented Thulsa Doom as one of the great overarching villains of Marvel's Howard-inspired sagas, a being whose evil spanned epochs.

The history of Thulsa Doom is a tale of immense ambition, dark magic, and a refusal to be conquered by death itself. His origins are deeply rooted in the ancient past of Earth-616, long before the rise of recorded human history.

Thulsa Doom was born a human man in the magnificent but decadent Thurian Age, approximately 100,000 years ago. This was the era of the continents of Atlantis and Lemuria, a time of powerful empires and potent sorcery. Doom was a brilliant and ruthless nobleman from the city of Valusia, the mightiest kingdom of the age. Consumed by a lust for power and forbidden knowledge, he delved into the darkest magical arts, making pacts with elder gods and demonic entities, most notably the Great Serpent god, Set. His arcane studies granted him unnaturally long life, and he rose to become a feared sorcerer-king. However, his path eventually crossed with that of a young barbarian from Atlantis named Kull. Kull, a warrior of unparalleled might and resolve, usurped the throne of Valusia, becoming its king and a sworn enemy of the serpent-worshipping cults that infested his new kingdom. Thulsa Doom became Kull's most persistent and dangerous adversary. Their conflicts were epic, pitting Kull's heroic strength against Doom's insidious magic and legions of followers, including the shape-shifting Serpent Men. In a climactic battle, Kull finally managed to defeat Thulsa Doom, seemingly killing him. But for a sorcerer of Doom's caliber, death was merely an inconvenience. Having transcended the limitations of his mortal flesh, Doom's spirit endured, mystically bound to his own skull. He became an undead entity, a lich of immense power. His physical form was destroyed, but he could manifest a new body of pure magical energy or possess others, often appearing with a terrifying, fleshless skull for a face. When a great cataclysm sank Atlantis and reshaped the world, ending the Thurian Age, Thulsa Doom survived. He spent millennia in the shadows, rebuilding his power and consolidating his leadership over the surviving Serpent Men. When the Hyborian Age dawned—the era of Conan the Barbarian—Thulsa Doom emerged as a god-like figure, the immortal head of the Cult of Set. He frequently clashed with Conan, viewing the Cimmerian as a reincarnation of the same heroic spirit that had thwarted him in the form of Kull ages ago. For Thulsa Doom, the battle against Conan was a continuation of an ancient war against the indomitable spirit of humanity itself. He has survived into the modern age, a testament to his incredible power and tenacity, occasionally crossing paths with modern heroes like Doctor Strange and proving that his ancient evil is eternal.

Thulsa Doom does not exist and has never appeared in the Marvel Cinematic Universe (MCU). This is a critical point of distinction. The character and the broader Conan the Barbarian mythos are not part of the interconnected film and television universe produced by Marvel Studios. This is primarily due to complex film rights issues. The rights to Conan and his associated characters have historically been held by other entities and are separate from the massive character library that Marvel Studios controls. While Thulsa Doom himself is absent, the MCU has explored themes and character archetypes that resonate with his role:

• Ancient Evil: Characters like Hela in Thor: Ragnarok or the demon Surtur represent ancient, world-ending threats that have been imprisoned or dormant for millennia, similar to Doom's survival from the Thurian Age.
• Charismatic Cult Leaders: The MCU has featured villains who lead devoted followers, such as Kaecilius and his Zealots in Doctor Strange, who are promised eternal life and power by the dark entity Dormammu. This mirrors Doom's leadership of the Cult of Set.
• Dark Sorcery: The corrupting influence of forbidden magic is a central theme in properties like Doctor Strange, WandaVision, and Doctor Strange in the Multiverse of Madness, particularly with the introduction of the Darkhold. The dark arts that Doom commands are philosophically similar to the power wielded by those corrupted by Chthon's dark magic.

Therefore, while fans hoping to see Thulsa Doom on screen in the MCU will be disappointed, his thematic essence—the ancient sorcerer, the cult leader, the master of dark magic—is represented through various other villains within the cinematic universe. Answering the common user question, “Is Thulsa Doom in the MCU?” the definitive answer is no.

Thulsa Doom's threat is not merely physical; it is mystical, intellectual, and spiritual. He is a force of nature, an ancient evil that attacks civilizations from within through corruption and decay.

Thulsa Doom's powers have grown over his hundred-thousand-year existence, making him one of the most formidable sorcerers in the history of Earth-616.

• Powers and Abilities:
• Master Sorcerer: Thulsa Doom's command of the black arts is nearly unparalleled. His expertise spans numerous disciplines:
  • Necromancy: He can raise the dead as mindless servants or potent undead warriors.
  • Illusion Casting: He is a master of deception, capable of creating highly convincing and elaborate illusions to trick his enemies or disguise his true form.
  • Summoning: He can summon and command a vast array of demonic entities, extra-dimensional beings, and monstrous creatures, including giant serpents loyal to Set.
  • Elemental Control: He has demonstrated the ability to manipulate natural forces, such as weather and fire.
  • Energy Projection: He can project blasts of raw magical energy, powerful enough to challenge even the strongest of warriors.
• Undead Immortality (Lichdom): Thulsa Doom is effectively immortal. His life force is not tied to his physical body but to his skull. As long as his skull remains, he can regenerate a new body, possess the bodies of others, or exist as a spectral entity. This makes him incredibly difficult to destroy permanently.
• Shapeshifting: A power granted by his patron deity, Set, Thulsa Doom can alter his physical form. He most often transforms into a colossal serpent, a reflection of his inner corruption and devotion. He can also assume the appearance of other humans.
• Superhuman Intellect: Having lived for over 100,000 years, Doom possesses a vast repository of knowledge, particularly concerning history, magic, and strategy. He is a patient and brilliant manipulator, crafting plans that span centuries.
• Master Swordsman: In his mortal life as a Valusian noble and king, Thulsa Doom was a highly skilled warrior and swordsman. While he now prefers to rely on his magic, he is still a deadly combatant should the need arise.
• Philosophy and Influence:
• Nihilism and Power: Thulsa Doom's philosophy is one of cynical nihilism. He believes that concepts like honor, love, and justice are fleeting illusions. The only true forces in the universe are power and will. He seeks not just to conquer, but to prove the futility of his enemies' beliefs.
• The Serpent's Creed: As the high priest of Set, he preaches a doctrine of submission to a greater, darker power. His cults offer their followers worldly power, pleasure, and freedom from morality in exchange for their absolute devotion. He corrupts societies from the inside, turning citizens against each other and dismantling civilization through decadence and fear.
• The Eternal War: He views his conflict with heroes like Kull and Conan as a single, unending war. He sees in them the defiant, chaotic, and ultimately breakable spirit of humanity. His goal is to finally crush that spirit and usher in an age of darkness ruled by his god, Set. His influence is felt through the Serpent Men and their human cults, who have infiltrated countless kingdoms and organizations throughout history, always working to further Doom's ancient agenda.

As Thulsa Doom does not exist in the MCU, this section serves as a comparative analysis of how his attributes are represented by other characters.

• Comparative Power Sets:
• Sorcery: The kind of dark, pact-based magic that Doom wields is most clearly seen in the MCU with the Masters of the Mystic Arts who turn to Dormammu for power, like Kaecilius. The ability to draw power from a malevolent extra-dimensional entity is a direct parallel to Doom's relationship with Set. Agatha Harkness and Wanda Maximoff (when using the Darkhold) also display a mastery of forbidden magic that corrupts the user, echoing Doom's nature.
• Immortality: The MCU has several examples of functional immortality. Hela from Thor: Ragnarok was an ancient being whose power was tied to Asgard and who could not be easily killed. The Eternals are themselves immortal synthezoids. However, Doom's specific brand of undeath (lichdom) has not yet been explicitly depicted in the MCU.
• Shapeshifting: This ability is most commonly associated with the Skrulls, who use it for infiltration and subterfuge, a tactic Doom would certainly appreciate. Loki is also a master of illusion and can change his shape, though his motivations are far more complex than Doom's straightforward pursuit of dark power.
• Comparative Philosophies:
• The nihilistic philosophy that “power is the only truth” is echoed by many MCU villains. Thanos, in his own twisted way, believes his will is the only thing that can bring order to a chaotic universe. Ultron comes to believe that humanity is a flawed concept that must be eradicated. These characters, like Doom, seek to impose their absolute will on a universe they see as flawed. The key difference is that Doom's motivation is tied to a specific dark deity and a desire for personal eternal power, whereas villains like Thanos often have a grander, if misguided, “utilitarian” goal.

Thulsa Doom is a solitary figure at the top of a vast pyramid of minions and worshippers. He does not have friends or equals, only tools and enemies.

• The Serpent Men: His most crucial and ancient allies are the Serpent Men, a race of pre-human reptilian humanoids created by the Elder God Set. The Serpent Men are masters of disguise, sorcery, and poison. Thulsa Doom rose to become their de facto leader after the Thurian Age, and they serve as his elite agents, spies, and assassins. Their ability to impersonate humans makes them the perfect tool for his strategy of societal infiltration and corruption.
• The Cult of Set: Over millennia, Thulsa Doom has cultivated a massive, widespread religion built around the worship of Set. This cult provides him with a limitless supply of fanatical followers, spies, sacrificial victims, and wealth. He is their living god and high priest, and they obey his commands without question. The cult is his primary instrument for destabilizing kingdoms and extending his influence across the globe.
• Kulan Gath: While they are often rivals, the ancient and powerful Hyborian sorcerer Kulan Gath has occasionally allied with Thulsa Doom when their goals align. Both are survivors of the same ancient era and possess immense magical power. Their alliances are always temporary and fraught with betrayal, as neither sorcerer is willing to serve the other, but their combined might represents a threat of the highest order.

• Kull the Conqueror: Thulsa Doom's original and most personal nemesis. Their conflict defined the final days of the Thurian Age. Kull represented everything Doom despised: barbaric strength, unwavering honor, and a fierce love of freedom. Kull's victory over Doom and his ascension to the throne of Valusia was a humiliation that the sorcerer has never forgotten, fueling a hatred that has lasted for a hundred thousand years.
• Conan the Barbarian: In the Hyborian Age, Conan became the inheritor of Kull's role as Doom's primary adversary. Thulsa Doom saw in Conan the same untamable spirit that had defeated him before. Their battles were legendary, pitting Conan's peerless fighting skill and cunning against Doom's overwhelming magical power and legions of cultists. Conan represents the perpetual thorn in Doom's side, the embodiment of the human will to resist tyranny and darkness.
• Doctor Strange (Stephen Strange): In the modern era, Thulsa Doom's activities have inevitably drawn the attention of the Sorcerer Supreme. Doctor Strange is one of the few individuals on Earth whose magical knowledge and power can match Doom's. Their confrontations are battles on a cosmic scale, with the fate of reality itself often hanging in the balance. Strange represents the ultimate magical obstacle to Doom's final victory.

• Leader of the Serpent Men: He is the undisputed master of this ancient race.
• High Priest of the Cult of Set: He is the central figure of worship and authority within the vast and insidious cult dedicated to the Elder God Set.

Thulsa Doom's appearances are often pivotal, marking major turning points in the lives of the heroes he confronts.

In his debut storyline, adapted in Marvel's Kull the Conqueror comics, Thulsa Doom served as the ultimate mastermind behind the serpent cults plaguing Valusia. He conspired with the Serpent Men to overthrow King Kull, seeing the barbarian king as an obstacle to his plans of returning Valusia to the dark worship of Set. This arc established the core tenets of his character: his leadership of the Serpent Men, his mastery of sorcery, and his deep-seated animosity towards Kull. The conflict culminated in a direct confrontation that solidified their status as arch-enemies for all time.

This storyline from the Kull the Conqueror series delved deeper into Thulsa Doom's nature after his initial defeat. It revealed that he had become an undead entity, his spirit anchored to his own skull. This was a critical development, transforming him from a mortal (albeit long-lived) sorcerer into a truly immortal and recurring threat. It explained how he could survive catastrophic defeats and return ages later to plague new heroes, setting the stage for his eventual appearance in the Hyborian Age of Conan. The Skull of Silence became his symbol and the source of his eternal undeath.

In the pages of Conan the Barbarian and The Savage Sword of Conan, Roy Thomas brought Thulsa Doom into Conan's era. These stories established that Doom had survived the sinking of Atlantis and spent thousands of years operating from the shadows. He was revealed to be the true power behind numerous threats Conan had faced, manipulating events from his dark temples in the land of Stygia. His confrontations with Conan were often more indirect and insidious than his battles with Kull. He would send demonic minions, empower rival sorcerers, or use his cult to ensnare Conan's allies, demonstrating his preference for long, complex schemes over direct combat. These appearances cemented him as Conan's most powerful and enduring magical foe.

Thulsa Doom's influence extends far beyond the pages of Earth-616 comics, with his most famous incarnation existing outside of the Marvel Universe entirely.

• Robert E. Howard's Literary Version: In the original, unpublished writings of Robert E. Howard, Thulsa Doom was conceived solely as a villain for Kull. He was a powerful sorcerer with a skull-like face, but his backstory and connection to the Serpent Men were less developed than they would become in the comics. He was a pure archetype of the evil wizard in the sword-and-sorcery tradition, a perfect foil for the heroic barbarian king.
• 1982 Film Version (Conan the Barbarian): This is arguably the most famous and culturally significant version of Thulsa Doom, portrayed with iconic gravitas by James Earl Jones. This version is a dramatic departure from the source material and is not part of Marvel continuity.
• Consolidated Villain: The filmmakers merged the character of Thulsa Doom with another Howard villain, Thoth-Amon, the leader of the Cult of Set. In the film, Thulsa Doom is the head of a massive serpent cult, a role that belonged to Thoth-Amon in the Conan stories.
• Revised Backstory: Instead of being an ancient enemy of Kull, this Thulsa Doom is a mortal man (though a powerful sorcerer) who personally raids Conan's village and murders his parents, giving Conan a direct and personal motivation for revenge.
• Philosophy of Steel: This version is famous for his “Riddle of Steel” philosophy, where he lectures a young Conan on the power of flesh and the steel that commands it. This cold, charismatic, and philosophical demeanor became the character's defining trait in the public consciousness.
• Powers: His primary magical abilities in the film are hypnotism, control over animals (especially snakes), and the ability to transform himself into a giant serpent.
• Impact: This portrayal, while not faithful to the comics, is so powerful that it has retroactively influenced how many people perceive the character, often overshadowing his original comic book identity as a skeletal-faced lich.
• Earth-1610 (Ultimate Universe): Thulsa Doom did not have a direct counterpart in Marvel's Ultimate Universe. The world of Ultimate Marvel focused primarily on modern reinterpretations of its core superheroes and did not venture into the Hyborian Age.

• Kull the Conqueror
