is a planet-sized Machine MutantDragon Ball GT: Perfect File, 1997 in Dragon Ball GT. It is Giru's home planet, as well as where Dr. Myuu keeps the One-Star Black Star Dragon Ball.
==Concept and creation==
The planet's name comes from the first letters of each word in "Machine Mutant".Dragon Ball GT: Perfect File Vol. 1, 1997
==Overview==
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", 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 the planet is composed of wastelands, but there is a huge city as well. As a result of their take-over of the planet, the inhabitants are all 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.
M-2's functions are linked to General Rilldo, who can merge with the planet as Meta-Rilldo to become the Planet of Metal. After Rilldo is dealt with the story continues to its peak upon Myuu's Planet.
