Planet M-2 was once inhabited by a highly advanced, technological race of humanoids who were all destroyed by the Machine Mutants. The race living on this planet seemed to be highly advanced and sophisticated, but were described in General Rilldo's story to be "unperfect", thus did not fit into Dr. Myuu's plan, and therefore they were murdered by "a more superior race"; which was apparently the machine mutants. The planet was then taken over and transformed by the Machine Mutants' creator Dr. Myuu around Age 760-770. A lot of parts on the planet are wastelands, but there is a huge city as well. The inhabitants are all robots or Machine Mutants.
In the Black Star Dragon Ball Saga, the Machine Mutant Giru guides Goku, Trunks and Pan through this planet as the plot revolving around his loyalty unfolds. There, Goku fights and defeats the Sigma Force and General Rilldo.
