Snow Serpents are the Arctic Specialist branch of the Eels (COBRA Frogmen). They must undergo the same rigorous training program as the Eels with the addition of a six month cold weather course somewhere above the Arctic Circle. Other aspects of their training include airborne operations (under arctic conditions), anti-tank procedures and the use of snow-shoes, skis and kayaks. "If the Eels are the elite of COBRA's naval branch, then the Snow Serpents are the best of the best. How else could you characterize an individual who would parachute onto an ice floe in sub-zero temperatures and then be prepared to march 50 miles with full field pack, assault rifle and anti-tank weapon?"
Snow Serpent is a Cobra operative in the original G.I. Joe: A Real American Hero line. First released as a Hasbro carded action figure in 1985, with 3 distinct figure versions produced across the 1982 to 1994 ARAH run.
Snow Serpent did not appear by name in the Sunbow or DiC cartoon series synopses. Original Hasbro file-card lore and Marvel ARAH comics appearances are the primary characterization sources.
