Grand Slam

Grand Slam is a U.S. military specialist who joined the G.I. Joe team, Marvel's elite counter-terrorist unit, from its earliest days. Trained in heavy artillery and laser weapons systems, he served as one of the squad's founding combat operatives.

Bronze Age born and battle-ready, Grand Slam made their mark right from the very first issue of G.I. Joe, a Real American Hero in 1982 — a debut it doesn't get more landmark than, crafted by the legendary Larry Hama and Don Perlin. Sharing pages across the decades with iconic figures like Scarlett, Cobra Commander, and a roster of memorable operatives, this character has been part of the G.I. Joe universe's DNA since day one. With 32 catalogued appearances spanning an remarkable 42 years through titles like Tales of G.I. Joe and publications from Devil's Due Publishing, Grand Slam is a testament to the enduring pull of that original Bronze Age launch. Three key-issue appearances seal the collector appeal — if you're building a serious G.I. Joe library, this is a name you don't overlook.
