The Eco-Villains team-up and, united, steal the Planeteers rings, and with them, their powers. The teens are stranded on the island of Commander Clash, a cold calculating military mind. He is tricked into going after the Planeteers by Blight, and succeeds, capturing Ma-ti and Gi. Without their powers, Planeteers are soon overwhelmed. Elsewhere, Dr. Blight creates dark variants of the power rings, and together, the eco-villains summon a dark, evil version of Captain Planet, dedicated to laying waste [literately] to the earth: CAPTAIN POLLUTION!
