Sci-Fi

Sci-Fi is a specialist soldier serving with G.I. Joe, the elite U.S. military counter-terrorism unit. His codename reflects a focus on advanced or experimental weaponry, fitting the team's tradition of highly trained operatives with distinctive technical specialties.

Debuting in the pages of The G.I. Joe Order of Battle #2 in 1987, Sci-Fi is a Copper Age addition to Marvel's beloved G.I. Joe universe — a character who carved out a niche among the Real American Heroes during one of the franchise's most exciting and expansive eras. Over nearly four decades of publication history, Sci-Fi has appeared across flagship titles like G.I. Joe: A Real American Hero, Action Force Monthly, and G.I. Joe European Missions, keeping company with heavy hitters like Flint, Roadblock, and the rest of that iconic ensemble. It's a testament to the enduring appeal of the G.I. Joe mythology that a character introduced in a reference-style Order of Battle issue has maintained a presence in the catalog all the way through 2025 — and for collectors who love digging into the deeper roster beyond the household names, Sci-Fi is exactly the kind of discovery that makes the franchise so rewarding to explore.
