Конан
Howard's Red Sonya had no connection to his Conan the Barbarian character. Roy Thomas and Barry Smith, in Marvel Comics' "Conan the Barbarian" title, transposed Red Sonya into the Hyborian Age, changing the spelling of her name in the process. "Shadow of the Vulture" itself was adapted by Marvel as a Conan and Red Sonja story of the same title in "Conan the Barbarian" #23 (February 1973).
