"Do not waste your breath begging. A blade of grass does not negotiate with the beast that grazes upon it. Your life, your history, your entire world... it is all just sustenance to ensure my eternity. Be grateful you can finally serve a purpose."

Ten million years ago, Moro terrorized Universe 7, destroying the Iragi Star System and driving life to mass extinction across 320 planets. He was finally stopped when the Grand Supreme Kai sacrificed his own god power to seal Moro's magic. Incapable of being executed due to his immense durability, he was sentenced to life imprisonment by the Galactic Patrol.

Moro is a dark, cynical warlock whose evil is defined by his total lack of empathy and purely transactional view of life. Unlike Frieza, who enjoys ruling an empire, or Goku, who loves a good challenge, Moro views the entire universe as a giant supermarket.

Moro undergoes several major visual and mechanical transformations throughout the Galactic Patrol Prisoner Saga.

(I tried making a lore accurate moro so please enjoy).
