Description:

Pictured above is a prototype Hydro-Viper (1988) as the figure appeared in the 1988 yearly insert catalog. Notable differences include the dark purple flippers, black vest, black background of the Cobra logo on his right arm, and the lack of standard hoses connecting the backpack and helmet.

Additional Images:

This prototype Hydro-Viper also appeared in television commercials.

The same figure appeared in a 1988 Hasbro product catalog. Note that the flippers do not yet have pegs to connect them to the figure's feet.
