In the late 1980s and early 1990s, Heck returned to Marvel, where his work included features for the superhero anthologies "Marvel Comics Presents" and "Marvel Fanfare". The artist even returned to two signature characters: He inked Hawkeye stories in "Solo Avengers" #17-20 and the subsequent "Avengers Spotlight" #21–22 (April–Sept. 1989) — both penciling and inking a second Hawkeye story in that last issue — and he drew Iron Man, inking penciler Mark Bright's eight-page "The Other Way Our" in "Marvel Comics Presents" #51 (June 1990), and both penciling and inking the one-page featurette "Tony Stark, The Invincible Iron Man" in "Iron Man Annual" #12 (Sept. 1991) and a pinup in "Marvel Super-Heroes" vol. 2 #13 (April 1993).
