Planet FM

Planet FM is a fictional planet from the Mega Man Star Force series. It is home to the FM life forms, or FM-ians, a race of aliens who have EM bodies who usually bear names of constellations and feed on human negative emotions. They are the main villains in the 1st installment, having destroyed the similar Planet AM and planning to destroy planet Earth due to their King's paranoa, although some of them are not evil and by the end their King decides to stop his actions and make up for his crimes. Their king is called Cepheus.

Andromeda is an FM-ian planet destroyer. It destroyed Planet AM and is the final boss of the 1st installment of the series, as it attempts to destroy Earth. It has a ball of loneliness at it's center, and it devours other EM beings. It's named after Andromeda, a constellation of a mythological princess, although it's gender is never revealed, as everyone refers to Andromeda simply by "it". However, it's more likely named after the Andromeda Galaxy than the constellation, as it is themed after a space planet-eating monster, then it transforms into a space-themed robot. Wether it's originally an FM-ian or it was built by the FM-ians itself remains unknown, but it seems to have a legendary reputation among them.
