Planet Majin is a free world. It is the homeworld of the Majins.
The high god Amoon created the Majin race himself. He originally planned on using them to conquer the universe for him. Instead, their race did not develop into a sophisticated enough society to be easily controlled. The Majins formed into small clans across Planet Majin's rocky surface, often engaging in turf wars and bloody battles. Over the years, the Majins destroyed much of the surface of their homeworld, leaving only craters and broken rocks to litter the ground. As wars reduced the Majin populations, more and more started to leave the planet and search for others to destroy. The vast depopulation of Planet Majin occurred before the Majin species became endangered.
By the time of From Magic to Monsters, the planet was a dead world. No trees, foliage, or animals roamed the rocky ruins. The last remaining true Majins, however, did still use the planet to hibernate in. The Majins would go through brief periods where they would leave their planet, rampage through the universe, then return to their planet and hibernate for quite a long time. Over the years, many Majins were killed or lost during their rampages. When Bibidi found the planet, only three Majins, Majin Sesami, Majin Hocus, and Majin Buu, were still using the planet. Hocus soon died and Majin Buu was buried in a cocoon below the surface of Earth. Only Sesami remained, but even she did not return back to her homeworld after being prematurely wakened by Bibidi. Perhaps she chose a different planet to hibernate on.
In the years following, Majin Jaduu began to use the planet to hibernate on. In roughly 3000 Before Age, members of the Corvos League hired Len, that era's Legendary Super Saiyan, to help them awaken Jaduu. She was able to, due to her massive power reserves. However, Jaduu was impossible to control. He broke free, nearly killing Len. He murdered the Corvos League geo-turfers and then began to rampage across the universe (Len eventually hunted him down and incinerated him).
In Age 751, Soba and Anso visited the planet in their fused Ansoba state. Due to the planet's high gravity, they remained there for some hours, training.
- Planet Majin was once home to several million Majins, making it one of the most dangerous places in the entire universe.
- Characters who were born on this planet include: Majin Sesami, Majin Hocus, Majin Buu, Majin Forash, Majin Elhim, Majin Shemash, Majin Forash, Majin Walu, Majin Simbari, Majin Simbara, Majin Salubi, and Majin Maanutar.
- Planet Majin used to be a lush, tropical planet, but the landscape was destroyed by the Majins' constant warring. Now the planet is just a rocky, inhospitable world.
- Several aliens have crash-landed on this planet, but all of them soon died, for there was no food or water on the planet to survive on. Much of Planet Majin's surface is covered in partially-destroyed space ships and the skeletons of their pilots.
- Planet Majin's Majin population:
- At height: 14,116,502.
- At lowest point: 0.
Planet Majin is still around.
