Well I have plenty of OCs but I'll go with Black in the future I might add more.
Seeing as Black casted was able to cast the god spell and spells that would instantly melt a ponies soul as soon as they looked at them I would say the entire universe of MLP would be instantly in peral chaos.
God Spell: This is a spell that when casted a pony will have control of universes, planets, destinies, etc.
