Well, op characters. At least Battler and Erika have their limits and weaknesses. Battler's weakness being that he purposely holds back and Erika's weakness is her overconfidence.

While I don't have the specifics of Erika and Battler, I do know that witches in Umineko can create and break down entire universes with ease. Even Bob/Deus can't do that.
