Kull 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). He's 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".
