Iron Man #46
Iron Man #46 delivers one of the most consequential character deaths in the early Bronze Age Iron Man run: the Guardsman, Kevin O'Brien, perishes in a battle against Tony Stark that was sparked by faulty armor Stark himself had built, making the tragedy a direct product of his own engineering hubris. The death reframes Tony Stark's heroism by attaching real, ongoing moral consequence to his dual role as industrialist and armored hero — guilt that the series would revisit for years. The event plants the seed for Michael O'Brien's obsessive vendetta against Stark, a subplot that enriched the Iron Man mythos through the late 1970s. For Bronze Age readers accustomed to reset-button storytelling, a superhero dying in the pages of his ally's book carried genuine weight.

The story 'Menace at Large!' was written by Gary Friedrich and pencilled by George Tuska, inked by John Verpoorten, and lettered by Sam Rosen, under editor Stan Lee with Roy Thomas as editor-in-chief. The issue was published with a cover date of May 1972 (store date February 8, 1972) and a cover price of $0.20. The Gil Kane and Ralph Reese cover was subsequently noted by collectors and critics as one of Kane's strongest covers from his Marvel work of the period. The Guardsman character had debuted in Iron Man #43, and Friedrich's script resolved his arc just three issues later — an unusually compressed character lifecycle that gave the storyline its punch.
