Writer Mike Friedrich and artist Jim Starlin‘s brief collaboration on the Iron Man series introduced Mentor, Starfox, and Thanos in issue #55 (Feb. 1973). Friedrich scripted a metafictional story in which Iron Man visited the San Diego Comic Convention and met several Marvel Comics writers and artists. He then wrote the multi-issue “War of the Super-Villains” storyline which ran through 1975.
Writer David Michelinie, co-plotter/inker Bob Layton, and penciler John Romita Jr. became the creative team on the series with Iron Man #116 (Nov. 1978). Micheline and Layton established Tony Stark’s alcoholism with the story “Demon in a Bottle“, and introduced several supporting characters, including Stark’s bodyguard girlfriend Bethany Cabe;Stark’s personal pilot and confidant James Rhodes, who later became the superhero War Machine; and rival industrialist Justin Hammer, who was revealed to be the employer of numerous high-tech armed enemies Iron Man fought over the years. The duo also introduced the concept of Stark’s specialized armors as he acquired a dangerous vendetta with Doctor Doom. The team worked together through #154 (Jan. 1982), with Michelinie writing three issues without Layton.
