Sub-Mariner #68
Sub-Mariner #68 is the formal first appearance of Force (Clayton Wilson) in his armored super-villain identity — a Bronze Age character who would later become a recurring figure in the Iron Man mythos, most memorably as a catalyst for the 'Armor Wars' storyline. The issue also marks the first named, on-panel appearances of amphibian scientists Professor Henry Croft and Dr. Joseph Jennings, whose roles at Hydro-Base would extend into Super-Villain Team-Up and beyond. Narratively, it anchors Steve Gerber's late-series attempt to give Namor a sustained quest — saving a comatose Atlantis — that provided the series with a sense of serial tension absent from its earlier years. Within Marvel's Bronze Age ecology, the issue also spotlights the Hydro-Base location, which would reappear for decades as an active setting in Avengers and related books.

By mid-1973, series writer Steve Gerber had taken sole charge of a book that was, by his own public admission in the Sub-Mariner #67 letters-page editorial, struggling creatively after Bill Everett's declining health and subsequent death had disrupted its direction. Gerber's solution was to pivot the title toward a multi-issue survival arc centered on a nerve-gas catastrophe threatening all of Atlantis, giving Namor a long-form problem to solve rather than another throne-usurper to repel. Issue #68 — scripted by Gerber, penciled by Don Heck, inked by Jim Mooney, and edited by Roy Thomas — was produced under that new mandate, with a cover by John Romita Sr. The issue was notable enough behind the scenes to warrant an in-book note from both Thomas and Gerber acknowledging a printing error that affected approximately 50,000 copies.
