Zeus

Lore
Before he became a god, Zeus was born as a wingless and powerless angel.. He trained hard and for a very long time to become what he is today..

Zeus as the Almighty created everything. He recreated the angels and created lots of rules to limitate their interaction with Humans. The law of the vessel was made so Angels can never reveal their true identity so their vessel would simply be destroyed at the exact moment they do. If an angel's true name is revealed it's vessel will be banned forever. Zeus renamed the Relic of the Knowledge into the mighty Zeus thunder to aid humanity in the great wars. He also created the first Seraphim (who became Hades later) as the Almighty.

As a god, he is powerfull but he is one of the 2 gods that could use their kamui in their vessel. As a angel, he stole the relic of knowledge from Chronos the Destrution and freed the world from humanity's dark ages
