Captain Planet and the Planeteers

Hoggish Greedly builds his son, Junior, a Road Hog for his birthday. When the locals see it and decide they want one of their own, Greedly suddenly sees dollar signs. He hijacks a factory run by Dr. Goodair, the creator of a fuel-efficient automobile, so he can assemble more Road Hogs to be sold. With smog polluting the air, only ones capable of stopping him in his tracks are the Planeteers.
