Moon

Moon is the only moon from the Earth. It can be seen in the night of episodes of the series.

The Moon is a big gray rock seen in the night with a white light shining upon the earth. Some aliens work at this location, like Lu. In The Return it is mentioned that Max was intended to be the first man on the Moon, but Neil Armstrong traveled to the Moon and not Max.

During Paradox, Professor Paradox travels with the team to an alternate timeline's future moon to show the gang what Earth would look like if he did not stop the time-traveling creature.

The moon is rarely visited by the team. During the episode Birds of a Feather, an Intergalactic Communications Station is revealed to be inhabited by Lu, and used a Crystal as a power source.

At the end of the videogame Ben 10 Ultimate Alien: Cosmic Destruction, Albedo in his Evil Way Big form is knocked by Way Big into space, reverting hi to human upon landing on the surface of the Moon. After cursing Ben out, Albedo is attacked by Lu.
