Deep-Six

Emerging from the Bronze Age action-packed world of Larry Hama and Frank Springer's G.I. Joe, a Real American Hero in 1984, Deep-Six is a durable corner of Marvel's beloved military comics universe — a character who has kept remarkable company over four decades alongside figures like Duke, Cutter, and Skip A. Stone. With 22 catalog appearances spread across G.I. Joe, a Real American Hero, G.I. Joe Comics Magazine, and beyond, and a publishing presence that stretches all the way to 2025, this is a character with genuine staying power in one of comics' most enduring franchises. Three of those appearances carry key-issue status, making Deep-Six genuinely worth tracking down for serious collectors who want the full story of this long-running Bronze Age original.
