The Mooners is a race of people that lived the moon, with their distinct features being the large number of holes. They were frightful of Abstract Jester and pressured the Unknown Spectator to creating the Geo-Robo. They endured some casualties in regards to the fight between Abstract Jester and the Geo-Robo.
They seem to be in a similar state like the Unknown Spectator, being oblivious to the blank canvas until a flash of colors manifested their world and later their consciousness. The design that was brought is similar to the moon, holes that represent craters. Their legs are derived from a microbiotic organism that's able to survive on the moon.
