"Ryan penciled the first six issues of "Quasar" in 1989–90, and also worked on a significant run of "The Avengers".Recalling Ryan's work on the latter title, writer Jason Versaggi said that Ryan's "draft work seemed to seamlessly transition from the end of John Buscema's stints on those books in the ‘90s.”

Other Marvel highlights included pencils for "Avengers West Coast" (shortly after inking John Byrne's art on several issues of that title) and "Ravage 2099", a character he co-created with Stan Lee.
