they all look suckers if they are compared with the 13 captains. Yeah they will show some of their powers which will be more powerful than the 13 divisions.
But I think Juha Bach will conquer Ichigo somehow to deal with these Zero Division Captains.
Ichigo may kill them using Complete Hollow Form or his newly known Quincy powers(???)
Later, he will be brought back to senses and will fight against Juha Bach.
