A classic Osamu Tezuka work! Three extraterrestrials are on a mission to see if Earth qualifies to be part of the Galactic Control. The Galactic Control is a select order of planets with strict admissions requirements. If Earth doesn't qualify, then the planet will be destroyed. To make progress in their mission, the three aliens abduct three earth animals as disguises for themselves. With their extraordinary powers, these aliens in animal skins are best known as the Wonder 3.
