BIO-VIPERS were once a battalion of ordinary COBRA EELS, until COBRA COMMANDER ordered them to "volunteer" for DR. MINDBENDER's experiment in DNA alteration. Dr. Mindbender bio-genetically crossed the Eels with an assortment of the ocean's deadliest predators, turning them into ferocious Mega-Monsters that stink like low tide! They have sandpaper skin like a shark, razor-sharp piranha teeth, and the strength and tentacles of giant squid! They became so violently out of control, Mindbender had to add computer integrated body & brain implants to control them! Now, when Cobra Commander needs vicious reinforcements, he calls the Bio-Vipers up from the depths and unleashes them on G. I. Joe. When they're not at work for Cobra, Bio-Vipers enjoy polluting the ocean, disrupting vital shipping lanes, and hunting innocent sea life! They must be stopped! But until they are, DON'T GO SWIMMING ALONE!!!!
