Thulsa Doom returns in Kull the Conqueror #11, 'By This Axe I Rule', based on an original story by Robert E. He was often a featured foe in the Marvel Kull comics (for instance, Kull the Conqueror #3 and #7). In comic books A powerful, Thulsa Doom is primary foe of Kull's comics version.
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'.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. The story did not see print until 1967 in the King Kull published by.Thulsa Doom is described by Howard in 'The Cat and the Skull' as having face 'like a bare white skull, in whose eye sockets flamed livid fire'.
This version was submitted to in 1928, but it was not accepted.
