Captain Planet and the Planeteers (1990)

S2E6 The Ark

An alien named Collectore, believing he is acting for the greater good, abducts the Planeteers, convinced that Earth is on the brink of destruction. He aims to gather human specimens to add to his collection of various extraterrestrial creatures. The Planeteers face the challenge of persuading Collectore that Earth still has hope, all while racing against time to stop Dr. Blight and Hoggish Greedly from annihilating a forest, which would lead to the extinction of the tiger population.
