Three Cubes to Darkness

Tomax is captured by G.I. Joe, causing his identical twin brother Xamot to plan on rescuing him before Cobra can activate the final cube in the "Sea of Lost Souls". Shipwreck and Snake Eyes find an ally in a pop singer named "Satin", who helps them escape Cobra's troopers in Enterprise City.

"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.
