Hydro-Vipers were animated only for commercials. The stingray was never animated.
Hydro-Vipers were introduced to the Cobra forces in late 1985 as a surgical upgrade to the already-elite Eels, with their appearance represented by Version 1. Hydro-Vipers ranked in the top tier of Vipers, above Eels and alongside Lampreys and Sea Slugs. They and the Eels were succeeded by Moray troops when Cobra re-emerged from its hiatus in 1991.

|Hydro-Vipers are qualified EELs (Cobra Frogmen) who volunteer to be surgically altered to withstand nitrogen narcosis and other side effects of deep diving. Synthetic webs are implanted between their fingers and subcutaneous fat production is stimulated by chemical injections to provide natural insulation. The long term effects of these procedures is known to be psychologically destabilizing . . . |
"I'm sorry, those guys just aren't human anymore. They have a handshake like a dead mackerel and they leave damp spots on all the furniture. I realize that they are virtually unbeatable in underwater combat, but so is a great white shark—and I'll bet the shark is friendlier!"
