Animorphs is a sci-fi series, primarily composed of a series of young adult novels from the 1990s and a television series adaptation. There are also a number of video games and toys.
The parasitic Yeerks are taking over the planet Earth, bit by bit, and the Andalites, who are fighting the Yeerks everywhere in the galaxy, don't have the resources to spare to save earth right now. Earth's only hope is a group of human teenagers, given the power to morph their bodies into animals by an Andalite hero. While they can only play the role of a gadfly at best, they hope to delay the invasion long enough for the Andalites to return and save the planet.
