If we're going to move into the territory of overpowered characters, we might as well just stop it.I was talking about the worst kind of viable character type to face in a battle. You know, the kind you could expect to see approved into the list.

In that case I'd just go with the character I posted at the top of this page.

As for OP, the latest battle in Bleach is all you need to see. One of them can bring anything he imagines to fruition (if he's to be believed), and yes, he has even brought out a meteor out of thin air now. Then there's his opponent who will be even more OP to be able to beat someone with the power of imagination. And you know he's going to win somehow.
