We begin this part far in the past, with the Great Lord of Lords and South Supreme Kai battling “Planet Eater Moro”, a robed warlock that kind of looks like a Saiyan great ape with ram’s horns. This master of magic has destroyed over 300 planets and added their power to his own, becoming nigh unstoppable. A strong introduction to a different kind of villain for this franchise.
Ultimately, the Great Lord of Lords manages to sacrifice most of his own power in order to seal away Moro’s magic and allow the Galactic Patrol to seal him away for 10 million years. 5 million years later, when Majin Buu went onto absorb the Great Lord of Lords and take on his fat and “innocent” appearance, the seal on Moro’s magic was released.
