Gaia, the spirit of the planet, assembles a diverse team of "planeteers," who are able to combine their powers to summon an elemental warrior that takes on the appearance of superhero Captain Planet. He works with the planeteers to defend Earth from pollution caused by criminals and villains. As the show's theme song says, Captain Planet is "gonna take pollution down to zero" by defeating the villains, who include the likes of Hoggish Greedly, Dr. Blight and Looten Plunder. The animated series was co-created by media mogul Ted Turner, a noted environmentalist.
