This Earth is the only known planet so far, and it's Earth number is unknown due to not being said yet and just being called Earth in the show. It supposedly has only one moon, but there are myths that there is more. Ben Tennyson rules this Earth, and is like a tyrant, willing to do or kill anything to get his way. Albedo leads a task force to overtake Ben Tennyson with the help of friends. There are elsewhere places on this Earth unknown to most of the planet where Ben has no control. This includes the land of Ooo, which has no set ruler and is broken up into kingdoms that are largely unaware of the outside population.
