Thulsa Doom was a frequent foe of Conan and Kull.

Seemingly immortal, he would be resurrected whenever he died.[citation needed]



Thulsa Doom claimed to have experienced his first death before the continent of Atlantis first rose from the ocean.[3] The Book of the Vishanti identified him as one of the last of the pre-human races dating back to the time of the Elder Gods on Earth,[10] and he was the part of the Elder Race proper.[6][7]

In the Age of Kull, Thulsa Doom claimed to be undead, having died "as men know death" long ages ago.[2]

as Ardyon, King of Valusia

Pre-Cataclysmic Age

He briefly replaced Kull as King of Valusian under the mortal guise of Ardyon.[1]

Thulsa was finally defeated when his skull and body were separated, not just through space, but time as well.[11]



Thulsa Doom was considered by Thoth-Amon to be the the greatest sorcerer in the days before the Great Cataclysm.[12] One of his most notable powers is shapeshifting, allowing him to claim various identities. Often impersonating someone else.[citation needed]


He was able to hold his own in a sword fight against Conan or Kull.[citation needed]


  • Thulsa Doom was created by Robert E. Howard in "Delcardes' Cat".
    • Ardyon was created by Howard, though the name was changed from "Ascalante" by literary agent Glenn Lord to avoid confusion with the eponymous character from "The Phoenix on the Sword".


  • It is speculated,[citation needed] but unconfirmed, that Thulsa Doom may have a connection to Doctor Doom. That speculation is based only on the fact they share the same last name.
  • Thulsa Doom was featured as the main villain in the 1982 Conan the Barbarian film, played by James Earl Jones. In the film, his appearance was more similar to that of Thoth-Amon.
