Firewall

Firewall burst onto the scene in 2002 when Devil's Due Publishing relaunched the beloved G.I. Joe universe for the Modern Age, debuting in the pages of G.I. Joe #3 courtesy of writer Josh Blaylock and artist Steve Kurth. Over a run stretching through the mid-2000s across titles like G.I. Joe and G.I. Joe: Frontline, this character carved out a place in a world populated by heavy hitters — sharing adventures with legends like Snake-Eyes, Flint, and the menacing Destro. With 22 catalogued appearances across that era, Firewall is a genuine piece of the Devil's Due chapter in Joe history, a rewarding find for collectors who love digging into the modern reinvention of one of comics' most action-packed franchises.
