Iron Fist is a fictional character appearing in American comic books published by Marvel Comics. Created by Roy Thomas and Gil Kane, Iron Fist first appeared in Marvel Premiere #15. The character is a practitioner of martial arts and the wielder of a mystical force known as the Iron Fist, which allows him to summon and focus his chi. This ability is obtained from the city of K'un-Lun, which appears on Earth every 10 years.

Marvel Premiere is an American comic book anthology series that was published by Marvel Comics. In concept it was a tryout book, intended to determine if a character or concept could attract enough readers to justify launching their own series, though in its later years it was also often used as a dumping ground for stories which could not be published elsewhere. It ran for 61 issues from April 1972 to August 1981. Contrary to the title, the majority of the characters and concepts featured in Marvel Premiere had previously appeared in other comics.
