Encouraged by the success of Ghost Rider and The Tomb of Dracula, both of which starred occult characters, Stan Lee proposed a series starring Satan, to be titled The Mark of Satan. Editor Roy Thomas had reservations about this idea and suggested a series focusing on the son of Satan instead. (Due to an oversight, “The Mark of Satan” is mentioned in a blurb in Ghost Rider #1).
The character Daimon Hellstrom first appeared in Ghost Rider vol. 1, #1 (Sept. 1973), then was spun off into a feature, “Son of Satan”, in Marvel Spotlight #12–24 (Oct. 1973 – Oct. 1975). During the “Son of Satan” run, Marvel Spotlight was a controversial series, with numerous readers writing to object to the depictions of satanism and wiccanism as being either inaccurate or furthering the cause of evil. Nonetheless, sales were strong, prompting Marvel to launch the character into his own series, Son of Satan, written by John Warner. The character’s success faded soon after the series launch, and Son of Satan was cancelled with issue #7, though an unused fill-in was published as Son of Satan #8 (Feb. 1977).
