The backbone of the Cobra Legions: highly motivated, superbly trained and formidably equipped. Every Viper carries a combination assault rifle and grenade launcher and wears multi-layer body armor with a wraparound composite helmet. "If you want to get anywhere in Cobra, you have to start out as a Viper. That's the bottom of the pyramid."
Viper is a Cobra operative in the original G.I. Joe: A Real American Hero line. First released as a Hasbro carded action figure in 1986, with 3 distinct figure versions produced across the 1982 to 1994 ARAH run.
Viper appears in 3 episode synopses across the Sunbow (1983 to 1987) and DiC (1989 to 1992) runs, first appearing in Sunbow's "The Viper is Coming" (1985). Full screencap and continuity review pending.
