Iron Man

Few characters carry a name as iconic as Iron Man, and this particular chapter of the armored Avenger's story — launched in 1983 by Denny O'Neil and Luke McDonnell — represents one of the most celebrated and dramatically rich eras in Bronze Age Marvel history. Across an extraordinary 42-year span in the catalog, this Iron Man rubs shoulders with the absolute cream of the Marvel Universe: Captain America, Thor, the Hulk, Hawkeye, and Clint Barton all share the page, a roster that speaks to just how central this character is to Marvel's grandest stories. With 98 appearances including 10 recognized key issues, and a prominent presence in the legendary Marvel Super Heroes Secret Wars as well as West Coast Avengers, this is a figure whose footprint in the collector's landscape is genuinely substantial. Whether you're chasing keys or simply following great Bronze Age storytelling, Iron Man belongs on your radar.
