G.I. Joe, a Real American Hero #80

Direct

The Joes and Cobras battle over a new but unstable island that has emerged from the ocean close to the location of Cobra Island, risen up from the underwater quake the Joes caused back in issue #'s 41 and 42. Both sides fail to keep control due to the island mass eventually sinking back under due its instability, and as the Joes are airlifted out in time, the Cobras have to swim home, their air transports not returning in time (not to mention their possible aquatic transports, the two Bugg vehicles present, were destroyed by the Joes new heavy weapons vehicle, the Rolling Thunder).
