A single Cobra Viper was present when G.I. Joe busted the Dreadnoks for dealing in Cybertronian hardware in Boston. He tried to fight back using a heavily armed and armored car, but his toys was quickly taken away from him by Snake-Eyes and his mech suit. The Viper was subsequently interrogated on Cobra's role in these illegal sales.
Several Vipers, including Percy, were present as Cobra tried to remotely hack into Teletran 3. This ended badly, as a G.I. Joe assault on the complex damaged their computer and warped everyone present to the planet Cybertron. Furthermore, it warped several Cybertronians into various points in Earth's history, causing a corruption in the timestream that threatened to destroy the Earth. Cobra and G.I. Joe were forced to join together, forming four teams that were sent through time and space to save their world. G.I.
