Destructive capacity: At least continent+ (Attracted considerable amounts of the Seireitei all the way to the Soul King Palace and melded them together with the structures in the Soul King Palace to create "WahrWelth", a new "country". Is the absolute God tier of Bleach at the moment), likely moon+ || At least planet+ (Attempted to reshape Soul Society. Was stopped in the middle of the process.)
