GI JOE COBRA VIPER Vintage Action Figure Sonic Fighters COMPLETE C9+ v3 1990
Viper (version 3) was released by Hasbro and was first released carded as part of the ninth series (1990) as part of the Sonic Fighters. He was discontinued domestically in 1991.
Viper came with a large gold backpack with buttons that made four different electronic battle sounds, a gold machine gun, a gold laser pistol, a gold pistol, and a three-piece gold grenade launcher.
Vipers are the grunts of the Cobra Legions. If there's a dirty job that needs doing, these guys are first in line. Vipers did all of the field testing on the Cobra-built, knock-off imitations of G.I. Joe's sonic weapons, which in itself should have earned each and every one of them the Cobra Medal of Villainous Valor with Bronze Serpent Clusters, considering how easy it was for these shoddy copies to self-destruct when fired. Outfitted with multi-layered body armor and wrap-around acrylic/composite helmets with built-in RTO* gear, Vipers are now armed with multi-burst laser pistols, 5.56 Colt Commando Rifles, 60mm surface-to-surface grenade launchers and standard issue 9mm Cobra service pistols.
