Planet Obidon is the fourth planet visited by Sonic and his friends. It was originally home to an unknown species of anthromorphic creatures. However, with the invasion of the Metarex, the planet's civilization was destroyed, and its Planet Egg stolen, leading to there being little to no life present on the planet.
