Thulsa Doom is an antagonist for the character Kull of Atlantis, debuting in the story “Delcardes’ Cat” (as Thulses Doom). He is the prototype for many of the future undead evil wizards in Howard’s stories, such as Tsotha-Lanti (in the Conan saga) and Kathulos (in the Skull Face novelette); other living or revenant Howardian practitioners of magic such as Thoth Amon, Thugra Khotan, Kathulos, and Xaltotun bear some psychological similarities to Thulsa Doom, even if their actual appearance is vastly different. Thulsa Doom is described 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 trampled 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”. Howard reused the character as “Kathulos of Atlantis” in his 1929 story “Skull-Face”.
