An experimental radar-defeating automated stealth plane prototype named Viper has crashed landed on a remote island in the south Pacific. Viper's AI programming is severely damaged, making it attack the Bionic Six. Meanwhile, Dr. Scarab has created a Molding Ray, a gun capable of merging more than one being into one. Scarab hunts down the Bionic Six on that same remote island, where, instead of hitting the Bionic Six, he hits the experimental plane. The plane merges with a snake, and becomes a new metallic snake-like entity set to destroy the Bionic Six.
