Snake Eyes must save Scott Abernathy and Spud while fighting Storm Shadow. Meanwhile with their headquarters destroyed the other Joes try to stop COBRA's new plan "Cobra Coast".

Baroness races against the Joes to secure a stone of power.

It seems that there are mysterious natural stones that have amazing technological powers that both Cobra and GI Joe are on the hunt for. When Zartan finds a Power Stone, it's up to Snake Eyes and Spirit to defeat Zartan and claim the Power Stone.

Vacation - The Joes take a vacation in Las Vegas where they end up stumbling onto a plot by Destro to use a casino as a front for developing a super-laser for Cobra Command.

Duke and the Joes head to Antarctica to infiltrate a Cobra Fortress. As Duke climbs perilous ice mountains to break into the fortress, the rest of the Joe team are fighting their way through legions of Cobra B.A.T.s with the Sigma Six Ice Saber vehicles.

When a Power Stone is discovered on Mount Arashikage, Snake Eyes competes with Storm Shadow to get to it. Meanwhile, Jinx and Kamakura fight the Dreadnoks.

When Scott Abernathy and his friends are visiting Cape Douglas rocket base, Cobra Command takes over the base and plans to launch a massive rocket into space to wreak havoc on the Earth.

Utilizing the Power Stones, Cobra Command creates the Zeus, a giant robot of unstoppable power. To help power the Zeus, Storm Shadow kidnaps Spud.

The Joes have to come together and use their combined technology to rescue Spud and destroy Zeus before it destroys the city.
