Battle for Terra (2007)

Mala and her friend Senn are young creatures of an alien race that inhabits Terra, a peaceful, near Earth-like planet that is part of a star system in the Milky Way galaxy and has a rich and advanced culture. One day, a large, mysterious object partially blocks the Terrian sun, piquing the Terrians’ interest. Mala, who is inventive and headstrong, goes against the Terrian rules that ban the development of new technologies without the approval of the ruling council and creates a telescope. She takes it outside the city and uses it to view the object. A lot of scout spaceships emerge from the large object, come down to the city and start abducting Terrians. Some willingly offer themselves to the spaceships mistaking them as their new “gods”.

After Mala’s father, Roven, is abducted, she lures a ship into a trap, causing it to crash. She saves the pilot, a human named Lieutenant James “Jim” Stanton. After his personal robot assistant, Giddy, warns Mala that Jim will die without oxygen (which the Terrian atmosphere does not contain), she scavenges suitable plants and creates a tent in which Jim can breathe. In exchange, Giddy teaches her human language. Jim awakes and finds out his ship is damaged beyond repair. Giddy tells Mala why the humans have come: centuries beforehand, both Mars and Venus were terraformed and colonized by humans for their natural resources.
