Who Was Omni King before Zeno?
Before Zeno, it was Beerus, but it was always clear that Goku was just a little bit away from catching up to Beerus. Who was the first Omni King? It is stated by Goku that Da'at is the First Omni-King in existence and as such Da'at is the most powerful god of 13 multiverses. Da'at is also the First Saiyan to exist in the 13 Multiverses and is thus the progenitor of the Saiyan race.
