Bio-Viper
By far my favorite Mega-Marine figure and possibly my favorite in the 90s the Bio-Viper. Genetically enhanced soldiers created by Dr. Mindbender. I guess I should've mentioned at the beginning, Mindbender was behind the Mega-Monster research. Instead of combining the DNA of histories greatest leaders the Bio-Vipers have been combined with the oceans deadliest predators. Once former Cobra Eels who were "volunteered" Mindbender injected them with the DNA of great whites, giant squid and moray eel. They are also cybernetically enhanced in order for Mindbender to "control" some what. The Bio-Viper is almost twice as big as a regular G.I. Joe and has most of the articulation in the arms. The legs and head do turn. The action feature is a fin on the back that when press down grabs and holds figures in its deadly giant squid tentacles. Another gimmick standard with each Mega-Monster is "Monster Smell" a stinky musk sprayed on the plastic of each action figure. Finally the Bio-Viper includes a spring action weapon that fires a missile or torpedo. It was also the only Mega-Marine not to include play do.
