these changes, Byrne's run is remembered for the introduction of the Great Lakes Avengers, an eclectic group of new superheroes. The Sensational She-Hulk During She-Hulk's tenure with the Fantastic Four, she appeared in Marvel Graphic Novel #18 (Nov. 1985) in a story titled The Sensational She-Hulk, which Byrne wrote and illustrated. On the request of editor Mark Gruenwald, Byrne wrote and drew a new series in 1989, The Sensational She-Hulk (maintaining the 1985 graphic novel's title). Gruenwald directed that it be significantly different from the character's previous series, The Savage She-Hulk. Byrne's take was comedic and the She-Hulk, who was aware she was in a comic book, regularly broke the fourth wall, developing a love-hate relationship with her artist/writer by criticizing his storylines, drawing style, character development, etc. Byrne left the book after writing and drawing the first eight issues. Byrne was asked for input on writer Dwayne McDuffie's She-Hulk: Ceremony limited series, and according to Byrne, most of his objections to the story and notations of errors were ignored, and his editor, Bobbie Chase, "was rewriting my stuff to bring it into line with" the story in Ceremony.

After writing and drawing the book for 25 issues, Byrne told editor Terry Kavanagh that he was starting to feel constrained on the book and thought having a different artist might inspire him to a fresh approach. Kavanagh suggested newcomer Jae Lee, and Byrne continued as strictly writer of the book up through issue #32. Byrne later said he has great fondness for the title character and was unhappy that circumstances forced him to leave the series. Iron Man Byrne took over writing Iron Man for issues #258–277 (July 1990-Feb. 1992), drawn by John Romita Jr. and later by Paul Ryan. Byrne launched a second "Armor Wars" story arc, restored the Mandarin as a major Iron Man nemesis, and featured the 1950s "pre-superhero Marvel" monster Fin Fang Foom. During the course of his run, Byrne became the first
