I wish to speak to you now. Where is the Eye of the Serpent? Rexor says that you gave to a girl, probably for a mere night's pleasure, hmm? What a loss. People have no grasp of what they do. You broke into my house, stole my property, murdered my servants, and my PETS! And that is what grieves me the most! You killed my snake. Thorgrim is beside himself with grief! He raised that snake from the time it was born.
~ Thulsa Doom

Thulsa Doom is a powerful ruthless and undead sorcerer from the Kull the Conqueror short stories and Conan the Barbarian fiction stories. He is Kull's arch-nemesis, in which he made his first appearance in the Kull short story "Delcardes' Cat" by the late Robert E. Howard. 

Since then, he has appeared in comic books and starred in the 1982 film adaptation as the main antagonist and nemesis of Kull. Later on, he started to appear in one of Howard's other creations, Conan the Barbarian. Thulsa Doom is the prototype for many of the future evil wizards, such as Thoth Amon, Thugra Khotan, and Xaltotun in later Conan stories.

He was portrayed by James Earl Jones, who also played Darth Vader in the Star Wars films, Ommadon in The Flight of Dragons, and The Emperor of the Night in Pinocchio and the Emperor of the Night.

A powerful necromancer, Thulsa Doom is Kull's primary foe. He was often a featured foe in the Marvel Kull comics (for instance, Kull the Conqueror #3 and #7).

Thulsa Doom returns in Kull the Conqueror #11, "By This Axe, I Rule," based on an original story by Robert E. Howard.

Posing as the nobleman Ardyon, he forms an alliance with four rebels within Valusia: the dwarfish Ducalon, the soldier Enaros, Baron Kanuub, and the minstrel Ridondo, who actually dethroned the hero. He set him on a quest to regain his lost kingdom, in the pages of his own comic, until it gets canceled.

Kull resumes his quest in the pages of Kull and the Barbarians, a black-and-white Marvel magazine format (published under the Curtis Magazines imprint). Thulsa Doom sent members of the Black Legion to ambush Kull and Brule, though they won the fight.

Thulsa observed the battle through a magic crystal. Kull and Brule's ship was later attacked by a sea serpent, with which Thulsa may or may not have had anything to do. Kull and the Barbarians lasted three issues until it was canceled. In the return of Kull the Destroyer, Thulsa Doom/Ardyon learned of the curse of Torranna (essentially, if a scarred man wore the crown and sat the throne, he'd be unable to ever leave the throne), which he determined to bestow upon Kull.

To this end, he took on the aspect of the god of Torranna and advised its inhabitants how best to bring this about. Thulsa Doom manipulated Garn-Nak, Karr-Lo-Zann, and Norra of Torranna. They drew Kull into Torranna and had him undergo a series of trials to gain the crown of Torranna.

Kull sought the crown because he believed he could use the army of Torranna to help him retake the crown of Valusia from Thulsa Doom. In Kull the Destroyer #28, Kull successfully completed the last of the trials, but before he could don the crown, Norra warned him of the curse of Torranna. Thulsa Doom allowed Norra's age to catch up with her, turning her into a shriveled corpse, and then revealed himself to Kull, challenging him to one final battle. In the next issue (also the final issue of the Kull the destroyer title), Thulsa Doom pulled Kull into a pocket dimension for their final battle.

Kull managed to slash Thulsa Doom's face with his sword but ultimately was overpowered by the necromancer. Thulsa Doom returned them both to Torranna, but Kull rallied long enough to push Thulsa Doom onto the throne and place the crown on his head. His face scarred by Kull, Thulsa fulfilled the prophecy and fell victim to the curse himself. Thulsa's power drained by the curse, the city of Torranna collapsed, seemingly crushing him. Kull, luckily, escaped, and then returned to Valusia to retake his own throne.

He would face Thulsa Doom at least one more time, in the pages of Marvel Preview #19 (summer 1979 issue). The script for that issue was an adaptation of the prose tale "Riders beyond the sunrise", itself the completion by writer Lin Carter of an untitled fragment written by R. E. Howard. Thulsa Doom appears to finally perish at the climax of this story, but he would eventually return as a Conan villain in the pages of Conan and a few issues of Conan's black-and-white magazine, Savage Sword of Conan (issues #190-193).

Thulsa Doom later becomes an enemy of the Celtic hero Cormac mac Art, another Howard character further expanded by Andrew J. Offutt. He is apparently immortal and is visualized as a skull-headed sorcerer, or as an albino when taking on the illusory appearance of a living man. A similar concept of an undead sorcerer can also be found in the lich from Dungeons and Dragons and other works of fantasy fiction, such as The Sword and the Sorcerer and Skeletor from He-Man.

Justin Sweet's take on Thulsa Doom.

Thulsa Doom first appeared (as Thulses Doom) at the end of the short story "Delcardes' Cat" by Robert E. Howard, which featured the character Kull as the protagonist. Howard later edited the text to include foreshadowing and references to Thulsa Doom (as he had been rechristened) throughout the story and changed the title to The Cat and the Skull to reflect this.

Editor Patrice Louinet speculates that this was because Howard had originally intended Kuthulos (whom Doom impersonates in the story) to be the actual villain before coming up with Thulsa Doom near the story's completion. This version was submitted to Weird Tales in 1928 but it was not accepted. The story did not see print until 1967 in the paperback King Kull published by Lancer Books.

Thulsa Doom is described by Howard in "The Cat and the Skull" as having a face "like a bare white skull, in whose eye sockets flamed livid fire." He is seemingly invulnerable, boasting after being run through by one of Kull's comrades that he feels "only a slight coldness" when being injured and will only "pass to some other sphere when [his] time comes. As Thulsa Doom's original story was not published in Howard's lifetime he reused the character, as "Kathulos of Atlantis", in his 1929 story Skull-Face.

1982 film adaptation


Thulsa Doom, portrayed by James Earl Jones.

Thulsa Doom serves as the primary antagonist in the 1982 movie Conan the Barbarian, where he is played by James Earl Jones, who is famous for voicing Darth Vader in the Star Wars franchise.

This Thulsa Doom is considerably different from the literary one, who is described as having a skull-like face. Pre-production drawings showed this version of Thulsa Doom with the skull-like face, but as film, he is essentially the classic Conan villain Thoth-Amon, servant of the serpent-god Set. As such, he appears as an ordinary human in the film, though one said to have lived for a thousand years and with the power to transform into an enormous snake.

This Thulsa Doom/Thoth-Amon hybrid appears to have been re-imagined as a cult leader in the manner of the real-life demagogues that had popped up in the decade previous to the film's release like Charles Manson or Reverend Jim Jones. In the movie, he is shown to have an extraordinary command of his followers. For example, in one scene, after Thulsa Doom commands one of his female followers on a high ledge to come to him, she jumps off the ledge to her death. In this, he resembled Hassan-i Sabbah, the Nizari leader, who according to Arab sources had one of his followers leap to his death to demonstrate his power to visiting dignitaries. Additionally, Sabbah's hashassans would leave daggers on the pillows of dignitaries to intimidate them as did the cult in the Conan film.

He appeared when he and his legions invade the lands of Cimmerians for the first time, leading to a massacre of the people there including the young Conan's parents (the father was killed by Doom's dogs while the mother was decapitated by Doom with the father's sword). As the young Conan became a gladiator after years of slavery, Conan swore to avenge his people's tragedy by killing Doom.

Upon getting a mission from the old king Osric (whose daughter was kidnapped by Doom), Conan disguises himself as a priest to infiltrate into Doom's Temple of Set atop the Mountain of Power attended by the massive "Children of Doom", the very cult whose soldiers slaughtered the Cimmerians, but he was caught, tortured, and later crucified on the Tree of Woe by the cult members. Fortunately for Conan, he was rescued by a female brigand named Valeria and an archer named Subotai, who all agree to help Conan rescue the princess.

Upon infiltrating the temple again, Conan and his trio manage to rescue the princess and deliver her out from the temple, but Doom kills Valeria by using a stiffened snake as an arrow to fatally strike her in the waist. The next day, Doom sends his men to go after Conan, but Conan, along with the help from the thief Subotai and the good wizard Akiro, manages to defeat Doom's forces, forcing Doom to flee back to his temple.

At the night following his men's death, Doom starts to address his cult disciples at the Mountain of Power, but he was interrupted by the arrival of Conan himself. Rather than killing him, Doom instead tries to mesmerize him, but Conan resists and instead uses his father's lost sword to finally behead Doom, thus avenging the deaths of Valeria, Conan's parents, and the Cimmerians. Following Doom's death, all of the followers are free from Doom's control and they return to their homes, right before Conan burns the temple. Then, he returns the princess back to King Osric afterward before heading to his next adventure with his new friends.
