Arch Majin

Arch Majin is a permanent evolution that eventually spun into it's own race, it is free usage(But your character has to've been an original Majin)

History
Hailing originally from Planet Zekonai, due to it's extremely powerful focus of magic, the first Arch Majin has become a form of dreams for the Majin. The first Arch Majin, who is named Arbadak, was extremely strong. He also possessed spiritual and magic powers beyond that of even well known mages of the time. The Arch Majin was so powerful that it literally burnt his ki out, limiting what would usually be a life of Eternal Age. Near the end of his death, he created sons, who had the Arch Majin energy in them as well. They didn't have as extreme of effects as their father, but soon their power would go down generation by generation of Majin.

In this age, the Arch Majin form is still very powerful, but not as intense as the original. It has stopped dividing it's power, and has reached a single point where it can't lower down through generations anymore.

Even Majin Buu had this power contained inside of him, but he never had a conscious in his original form due to his creator (though there are many Majin that do). This made it hard to get him to train, so his potential pretty much went stone cold.
