Muskrat

Muskrat is a G.I. Joe operative who specializes in swamp and wetlands combat, bringing guerrilla survival expertise to the elite counter-terrorist team in their ongoing fight against Cobra.

Muskrat splashed onto the scene in 1988, debuting in the pages of G.I. Joe: A Real American Hero #80 — a Larry Hama and Ron Wagner creation born right in the thick of the Copper Age, when that legendary Marvel series was firing on all cylinders. Over nearly four decades, this character has kept remarkable company, sharing adventures with icons like Snake Eyes, Scarlett, and Shana O'Hara across one of comics' most beloved military action franchises. With 17 catalog appearances stretching all the way to 2025, Muskrat is a testament to the enduring world Hama built — a corner of that universe worth exploring for any fan who loves the deep cuts of the Real American Hero roster.
