Cobra's Creatures

Cobra uses a special weapon called "Hi-Freq" given to them by an evil scientist named Dr. Lucifer, which a mind control device that takes over all animals in the animal kingdom, including Mutt's dog Junkyard. G.I. Joe has to stop Cobra's Hi-Freq device and save every animal in the world, especially Junkyard who isn't man's best friend, but Mutt's worst enemy.

"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.
