Astro Boy: The Glorious Earth

Original title: ASTRO BOY 鉄腕アトム特別編 輝ける地球（ほし）〜あなたは青く、美しい…〜

A boy is chased by a robot through some ruins. There, he finds an Earth ruled by a computer called "Gaia," who has lost patience with humans who repeatedly cause war and environmental destruction. While desperately trying to escape, the boy discovers Atom, which had been put on display 200 years ago after it had finished its role.
