Captain Planet S4 Ep 5 - F2F Body Swaps

Season 4 Episode 5 The Unbearable Blightness of Being
Dr. Blight succeeds in constructing a machine, which switches the minds of two affected bodies. Using this machine, she gets into the body of Gaia (as well as Gaia gets into hers), in this way gaining Gaia's powers of nature and also fooling the Planeteers. Imprisoned in Blight's body, Gaia has to find and convince the Planeteers, if she wants her own body back.
