Plot:
Several skystrikers land right before Cobra attacks. Returning to the air, the Joes drive the fiendish reptile group away.
In Cobra’s secret base, Destro is getting chewed out by Cobra Commander. They plan to test the mass device which is powered by
3 elements.
General Flagg meets with Duke and Major Juanita Hooper, the penny pincher.
"I see my double-chinectomy is in 5 minutes."
The Joes are to insure that a new satellite is secure until it’s launched. Immediately, the Joes quickly break through the security and into the
room with the satellite. Hooper places a homing device on the satellite.
Destro beams in an army of Cobra soldiers to seize the satellite. Hooper is actually the Baroness. The Joes are driven out of the
room. Before Destro beams out, Duke is caught and beamed off with them, too.
In the Cobra base, Duke is quickly overpowered. The satellite is sent into orbit. Now they can use their mass device with the satellite
without using homing devices. Cobra Commander has the Eiffel Tower beamed away.
Cobra Commander broadcasts on all the TV stations his demands. Surrender or else.
In the slave pits, Duke awakens. Everyone wears headbands and wander around aimlessly. Baroness explains the slaves are
mindless but Duke will have to fight in the ARENA.
The Joes try to find Dr. Vandermeer who created the mass device. It is a trap by Cobra which the Joes manage to evade. They find
Vandermeer. Only another mass device can counter Cobra’s one. However, it is powered by 3 extremely rare elements.
In the arena, Destro controls Duke and has him fight a giant.
"By CROM, THUNDARR shall fall at my feet..."
Back at Joes base, Vandermeer explains the first element is a radio active crystal found only in the Arctic Circle.
Cobra Commander learns that the world has refused to surrender and the Joes are going after the elements.
In the slave pit, Selena, a slave girl, offers to help let Duke escape and show him how to block the headband controls.

the mass device running low on fuel. Cobra Commander heads back to the Arena.
At the Arctic mine, the Joes are fighting the giant Cobra robots.
Back at the Arena, Cobra Commander and Destro start arguing. Duke uses the time to jam his headband before escaping. Selena

Back at the mine, Major Bludd send in a robot to retrieve the crystals. They’re surprised when Snake Eyes wanders out. Bludd is sure
he’ll be dead from radiation poisoning in a few hours and lets him go.
The Joes are over the deepest trench in the ocean to retrieve the heavy water before Cobra.

mountain man takes Snake-Eyes
to the cabin.

defend the satellite. Snake-Eyes return with the crystals. The canister suddenly starts emitting some gas. All the Joes collapse.
Timber is able to rouse Cover Girl who gets the canister away before it explodes. They plan to go after the final element which is in the
ring of fire. The Joes are also ordered to surrender. Cobra Commander overhears the order.
However, the Joes anticipated their communications would be tapped and used this as a diversion to get enough time to retrieve the
element.
In the volcano, the Joes start to lift the meteor up. Cobra shoot the meteor free and try to force the volcano to erupt.
At the Cobra base, Cobra Commander decides to destroy New York City and launches the mass beam at the city. Selena sees and

and board. Scarlet chases Destro who is retrieving some of the element. He captures Scarlet and uses her as a shield to get away.
