Wonder World is the home planet of Turbo Thunder. It is inhabited by a race of people called Meta-Humans, and everyone in this world has super powers. It was one of the first planets destroyed by the Darkness.
It is an average sized planet that looks gold from space, with three orange moons surrounding it.
Turbo Thunder lived with his parents happily until the Darkness appeared. The inhabitants attacked the Darkness with rockets, so in turn, it sent The Eliminators to attack the planet. During the attack, his parents were absorbed by the Darkness, after they sent Turbo Thunder into the space. The whole planet was absorbed by the Darkness.
Turbo Thunder himself as seen at the end of Part 1: The Big Beginning.
