|BriefSynopsis=Both G.I. Joe and Cobra obtain one of three pieces of the Weather Dominator. They now do battle to collect the third part, the Laser Core, at the icy Roof of the World.
To save the lives of Gung-Ho and Shipwreck, Lady Jaye throws a javelin, which strikes the side of the canyon, shoots a net across to the other side and catches Shipwreck and Gung-Ho. Shipwreck draws back the net with the aid of a hook and line and both he and his teammate are flung to the top of the earth.
Cutter orders Doc to create a smokescreen so that he can send a party to the other side of the island, and as soon as the Joe smokescreen is up, Cobra creates one of their own. Cutter then notices Freedom circling the waterfall and wonders what has happened to Spirit. Trapped inside a cavern, Spirit and Storm Shadow continue to fight until both realize that the fight is pointless since the amount of oxygen is limited in the cave. They sit down and begin to ponder the situation.
Roadblock and Honda Lou arrive at Cobra Temple and smuggle themselves inside by remaining in the trailer. Destro, meanwhile, reviews the progress of the Weather Dominator project until Cobra Commander enters the room. While reporting on the progress of the retrieval missions, Destro walks to a table projecting a hologram of the location of the laser core: the Roof of the World.
In the cavern on the Island of No Return, Spirit tells Storm Shadow that he has a solution to their predicament. Since the water forces the air out of the cavern, Spirit theorizes that there must be a blowhole on the island which they can use to escape. Each takes a deep breath and they are swiftly carried out of the cavern as they are under the Weather Dominator fragment. They escape and Storm Shadow thanks Spirit for saving his "unworthy life" by letting him have the component.
As Spirit climbs the side of a cliff, he is watched by Zartan, who is in a submarine with his Dreadnoks. Cobra's Master of Disguise fires a torpedo toward the island so the Cobra agents following Spirit are knocked off the cliff and will not catch him. The Dreadnoks are confused as to why Zartan would want the Joe to win. After all, they are on Cobra's side, aren't they? Zartan explains that they are - first and foremost - on their own side and that the Dreadnoks will understand his plan in due time. The island is soon destroyed by molten lava from cracks in the bottom of the ocean and the Joes escape by Dragonflies while Cobra flees in Rattlers.
