Molten men held a place within the traditions of the Mustafarian people. As Priestess Sssl explained, their role was to deter lizard-crows, beings that gathered in the lava expanses of the volcanic planet Mustafar. Around 12 BBY, during Mother Sssl's attack targeting the fortress belonging to the Sith Lord Darth Vader, she drew a comparison between the molten men's impact on lizard-crows and her own efforts to frighten away the Sith Lord along with his Imperial military from her native land.
The concept of molten men appeared in flashback sequences within the fifth edition of the Star Wars Adventures: Return to Vader's Castle comic book series from 2019. Cavan Scott authored the issue, which IDW Publishing released on October 30, 2019.
