High Quality Content by WIKIPEDIA articles! G.I. Joe Extreme is a line of military-themed toys from Hasbro and the next major incarnation of G.I. Joe after G.I. Joe: A Real American Hero folded in 1994. The series ran from 1995 to 1997. It was actually preceded by Sgt. Savage and the Screaming Eagles, a one-time only series that filled the hiatus between A Real American Hero and Extreme. The only character from that line that was carried over was Sgt. Savage himself. Because of Sgt. Savage s inclusion, the Screaming Eagles series is considered by some collectors to be part of the G.I. Joe Extreme series even though it was actually labeled as part of the Real American Hero line.
