In 2009, Thomas explained he had been a fan of the soundtrack to the musical Jesus Christ Superstar and sought to bring the story to comic books in a superhero context: “Yes, I had some trepidation about the Christ parallels, but I hoped there would be little outcry if I handled it tastefully, since I was not really making any serious statement on religion… at least not overtly.” Choosing to use a preexisting character while keeping the series locale separate from mainstream Marvel Earth, he created Counter-Earth, a new planet generated from a chunk of Earth and set in orbit on the opposite side of the sun. Thomas and Kane collaborated on the costume, with the red tunic and golden lightning bolt as their homage to Fawcett Comics‘ 1940s-1950s character Captain Marvel. The story continued in the series The Power of Warlock, which ran eight issues (Aug. 1972 – Oct. 1973)
Writer-artist Jim Starlin revived Warlock in Strange Tales #178-181 (Feb.-Aug. 1975). Warlock’s adventures became more cosmic in scope as Starlin took the character through an extended storyline referred to as “The Magus Saga.”
The reimagined title continued the numbering of The Power of Warlock and began with Warlock #9 (Oct. 1975) and ran seven issues. The bimonthly series was initially written and drawn by Starlin, but was eventually co-penciled and inked by Steve Leialoha.
