Zeus was in a now destroyed alternative universe where he attempted to reason with Yahweh until a series of construction and deconstruction events happen to him, He snapped and destroyed Yahweh in a altered form.
Now these days he sits by himself a lot and has a hard time cope with those events. On Rare events he begins to sob about the situation.
Outside of his PDSD he is fairly free spirited and enjoys helping out the earth in any way he can. One word can describe him. Multicultural.
