After drawing some house ads and a frontispiece for two of Marvel Comics' black-and-white comics magazines, Niño teamed with writer-editor Roy Thomas on a 17-page adaptation of the Harlan Ellison short story "'Repent, Harlequin!' Said the Ticktockman" in the black-and-white Unknown Worlds of Science Fiction #3 (May 1975). This led to a 30-page Conan the Barbarian tale, "People of the Dark" in The Savage Sword of Conan #6 (June 1975), also with Thomas, and a 23-page adaptation of the Michael Moorcock novel Behold the Man, with writer Doug Moench in Unknown Worlds of Science Fiction #6 (Nov. 1975).
