The Vines of Evil

Cobra Commander has Duke and Snake Eyes fight each other in a gladiatorial combat in his "Arena of Sport". Cobra plans to assault Washington D.C., but Duke and Snake Eyes send a Morse code to their team. The Joes successfully defend D.C., but they destroy the weather device by splitting it into three pieces scattered globally. Weather patterns all over the world are in havoc; G.I. Joe must recover the three parts before Cobra, or all is lost.

"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.
