"Crashing through the skies, comes the fearful cry... COBRA!" Heli-Vipers are a fearless unit of Cobra agents trained for the most perilous missions. They are the elite of the elite in Cobra aviators. A Cobra interested in becoming a Heli-Viper is personally selected and screened by Cobra Commander himself! One segment of their training involves preforming extremely risky aerobatic maneuvers under live fire, blind-folded and without any weapons. Needless to say, any candidate who does not pass this portion of the training is out of the program ... permanently!
