M51 Galaxy

From Power Rangers Universe

M51 Galaxy (also known as Gamma Vile) is Master Vile's home planet. On its rocky surface, Master Vile lives within a fortress around which a road spiraled up to its front gate. In its purplish sky above were three silvery moons, perhaps artificial.

Thousands of years ago, the people of galaxy M51 had hid the Zeo Crystal from Master Vile deep inside the Caves of Deception, beneath the surface of the Earth's moon, and placed a powerful forcefield around it to protect it from anyone not pure of heart.

All of Master Vile's guards wore imperial red uniforms and were either green-skinned dragon-men or brown goat-horned men.
