2x7 - Captain Planet and the Planeteers

The Planeteers are saved from crashing by a solar beam, created by Dr. Pollo. He and his daughter live on an island, creating new and innovative ways to use solar power. Kwame falls in love with his daughter, while also becoming suspicious of their lab assistant, who turns out to be Leadsuit, sidekick to Duke Nukem. Nukem's plan is to turn their solar convertor box into a nuclear device, so he can feed on the nuclear energy generated by the beam that saved the Planeteers earlier. The Planeteers and Captain Planet stop Nukem in his tracks, but shocks from the nuclear energy erases Dr. Pollo's memory, prompting him to set out to rediscover his inventions.
