Native inhabitants of the Earth's moon, the lunar moths become protectors of the baby MiM. When MiM was still very small, a moth came to him every night and flew him into the stars so he could see his parent's constellation. The Lunar Moths remain MiM's constant friends to this day.
The Glowworms are giant worms that light up bright enough to read a story by. When MiM was a tiny baby, the Glowworms gathered around his mother so she could read to him from The Primer of Planets. When MiM is older, the Glowworms gather around him on the moon so that he can tell the Guardians his plans for protecting the children of Earth.
The Moonbots were the crew of MiM's ship, Moon Clipper. Dedicated to serving and protecting MiM and his family, the Moonbots are loyal companions, although sometimes the dry air of the moon leaves their robot joints creaking.
The Moonmice are some of MiM's oldest friends. When MiM was a very small baby and his mother and father told him stories of the Golden Age, the Moonmice gathered along side him to listen too.
