The Palace of Doom

Cobra and the Joes head for "The Palace of Doom", an alleged cursed Aztec temple, to retrieve the first fragment, the "Ion Correlator". Cutter, Wild Bill and Spirit along with Doc, Torpedo, Clutch and Rock 'n Roll head to an unstable island in the Pacific called the "Island of No Return" to retrieve another fragment, the "Hydro Master", and are opposed by the Baroness, Firefly and Zartan. The Joes retrieve the correlator, but they lose the fragment to Major Bludd during an earthquake.

"Now you know. And knowing is half the battle." The Sunbow run closed every episode with a public-service spot delivered by a Joe character, addressing kids on a real-world hazard or virtue. The cartoon's deeper ethic, threaded into the writing across the run, was that Cobra's worldview was based on fear and the Joes' was based on responsibility.
