Captain Planet and the Planeteers - Season 2 (1991)

On Moghal Island, Looten Plunder plans to open a factory and hires Dr. Blight to use her cloning-ray to give him many workers so he won't have to pay them much. The Planeteers don't know exactly what the two are planning as go to investigate, but after they arrive and meet an ambitious but unappreciated local girl named Leela, they're just in time to see her lazy brother Vico captured. Blight and Plunder didn't get to keep their first test-subject, a locust, to see how and what would happen when it clones, but use the ray on Vico anyway. The Planeteers and Leela get ...

Gi tells Ma-Ti the shark he thought was attacking him during their swim on vacation was a plant-eater, but a Florida Keys local overhears and misunderstands part of their conversation and soon the town believes the beach is overrun by man-eating beasts. Argos Bleak takes advantage of the promises of a reward for someone who will keep the people safe by vowing to kill all sharks. Ma-Ti and Gi try to warn people that harming sharks will mean harming the environment when the animals they control become too populous, then attempt to stop Bleak's hunting, but they are ...

The Planeteers are trying to save the tigers whose habitat is being destroyed by Greedly and Blight, when suddenly they are abducted by an alien who collects endangered animals.

Professor Apollo invents a solar beam which can power anything, but Duke Nukem steals the beam and converts it into a deadly radiation ray to power himself. The Planeteers must stop Nukem before the ray destroys the island.

Hoggish Greedly introduces "dynamite-fishing" to the Philippines, since fishing by placing explosives in the water quickly kills fish...and is the perfect cover for him to dig in the coral reef their ocean ecosystem thrives on and steal and sell its remains. The Planeteers arrive to caution the locals to stop using explosives before the reef, and ultimately their way of life, is destroyed. They have trouble convincing Marcaria, a fisherman's wife, that any gains made will be overshadowed by the losses of sea-life and the length of time the reef would take to grow back...

In San Francisco, many are falling sick to poisonings of what look like various toxins and chemicals. The Planeteers go to investigate. Ma-Ti's obsession for old mystery novels makes him eager to prove how good a detective he is. However, none of them notice Verminous Skumm's presence when every place they examine is sabotaged and those they get information from sicken. Ma-Ti's distractions don't help the others learn everything soon enough to solve the problem, so they have him stay behind while they meet a talking mime who invites them to a restaurant at the Bay ...

The Planeteers get shrunk to microscopic size and put into polluted water, which Kwame drinks. They battle hideous water-borne parasites in Kwame's body so that he can recover, and the Planeteers restore themselves to proper size.

The Planeteers visit an organic farm to see how natural insect-repellents are used on crops, but Joe, a neighboring illiterate farmer too ashamed to admit he can't read, receives a job offer operating sprayers from Looten Plunder and Argos Bleak. Their machines are full of pesticide that not only kills the insects, but also other animals. This nearly causes a mass- poisoning when a cloud of it heads for the town. The Planeteers succeed in warning Angela, a schoolteacher, and her students, and Captain Planet removes the gas before leaving. The Planeteers decide to ...

While touring the desert, Ma-Ti is surprised how many animals live there - but is even more shocked to see that it's the spot Hoggish Greedly has chosen for his off-road racing, despite the threats his guide Josh says it gives to the animals there. Gaia reveals also that even small vehicles cause bad damage by unleashing much sand that will be eroded during a rain and prevent plants and animals from surviving. The other Planeteers join Ma-Ti and Josh to find Greedly already attacking, getting a young dirt-biker named Pete on his side by claiming there's nothing to ...

During a boating voyage, Hoggish Greedly and Verminous Skumm land on the Galapagos Islands after Greedly accidentally knocks a toxin over Skumm's rats, causing them to grow and mutate form. They find some endangered Galapagos tortoise eggs, and plan to use them for food. The Planeteers, sent by Gaia to a museum with a camera-operated robot called JASON which can explore anywhere, see the two poaching and fly out to stop it. They have to defeat Greedly, Skumm, and the mutant rats, and even Captain Planet has to get past their supply of toxins in order to help.

After rescuing George, a miner whose leg is caught in an area under construction, the Planeteers are horrified to see how strip-mining is used for finding minerals, proving disastrous to the environment and dangerous for people. They investigate the mine and find that while Hoggish Greedly is in charge, he is actually working under the mine's owner, Sky Runner, a Native American musician Gi and Linka like who is supposed to be an environmentalist. They go to meet him and learn that strip-mining wasn't his idea, and he goes to confront Greedly. He is kidnapped along ...

The Planeteers go to investigate and meet a local journalist, Sam, who is also trying to figure out why nobody is riding the metro. There have been claims of disappearances, though no missing-person reports, while some cars vanish and the ones that operate see appearances by what look like phantoms and go for crazy roller-coaster rides on hidden tracks. Kwame and Wheeler sneak back to walk through the tunnels, and discover that Looten Plunder has ...

Linka and Ma-Ti go to visit his ornithologist friend Juan in Central America, and explore a valley of many birds with Juan's parrot, El Profesor. However, he and all the other birds end up following a bird that is actually Hoggish Greedly's robot to lure them into his trap for smuggling them off. When they attempt to free the birds, Ma-Ti and Linka are captured, and Ma-Ti strikes his head against a pole so finds it too painful to contact the others. The other Planeteers hear that they are missing so go after them, and El Profesor escapes and is able to let the others ...

Zarm joins forces with Hoggish Greedly, Looten Plunder, Sly Sludge, Duke Nukem, Verminous Skumm, and Dr. Blight. Zarm tricks the Planeteers into giving up their rings and zaps Gaia into human form, aging her and destroying the planet.

But when an earthquake strikes, they go north to Santa Teresa to rescue victims - and during an aftershock, Wheeler is knocked on the head by stone and, found and rescued by a couple moving to the city, awakens to find that he has amnesia. He hears Ma-Ti calling to him in his head but doesn't know his voice, so is suspected to be mad and flees the hospital he is left at. He falls in with Teresa, a young woman who attempted to be his guide earlier, and learns ...

Hoggish Greedly uses a large machine to uproot trees from the ground and grind them at the same time so he can have a quick, easy supply of wood to sell furniture. The Planeteers arrive to see what is causing the destruction of forests that is believed to be a "flying saucer", with the help of Jenny, a local teen birdwatcher whom Wheeler finds attractive. They must fight Greedly's machine causing destruction for themselves and others...and they may have to do it alone, since when Captain Planet is caught and injured in the grinder while rescuing a nest of birds, he ...

A roofless dictator decimates the land to fight the opposition, with total disregard to the environment and human life. But there is more to the story than meets the eye. The dictator is really an old foe of the Planeteers in disguise.

Venice's population is relocating due to its pollution and smog affecting the land and structures - but also because of a large mutated group of rats whose bites sicken their victims.

But it isn't until Ma-Ti is bitten, and badly suffers, that they learn that Skumm is doing it through a substance placed in processed cheese that causes the rats and whoever they ...

Looten Plunder leads a whaling operation with Dr. Blight aboard attempting to concoct the perfect poison, and the Planeteers are enraged to see that it is legal for him to kill whales with calves - as the Japanese whaler Masuyo would rather not do - simply because he claims that he is "experimenting whale-repellent". Masuyo's son Tykoshi fails to plead with his father not to hunt so resorts to stowing on the Whale-B-Gone ship, but is accidentally knocked overboard by one of Blight's beakers, and rescued by the Planeteers. They join forces to try and find evidence that...
