AlienWarlord
He got all the smarts and people to make a Prison similar to Arkham for super powered people and magic users especially if one of the cells is linked to the mirror universe and locked in that specfic space so no damage is done to the outside while still being in the regular universe. Being that with runes they could if they wanted to nullify certain powers such as access to magic and using tech to null meta powers also if the runes donât work.
