In 1982, Hasbro and Marvel Comics kicked off a battle of good versus evil when they launched the G.I. Joe: A Real American Hero comic series and toy line that pitted the valiant soldiers of the titular military unit against the vile forces of the terrorist organization known as Cobra. 41 years later, that struggle is an ongoing and epic one that has captured the imagination of generations of fans. Most of its memorable moments sprang from the mind of one man -- writer Larry Hama, who kicked off the Marvel Comics run and wrote almost all of the series' 155 issues.
