Ichigo has a lot more poweful back up. The only one that seems to be on par with Ichigo is Ishida and I do not know if that is really the case or not. I don't know how poweful Chad is, but he does not seem to be nearly as strong as a Ichigo. He has yet to fight, so I will not know his strength yet. So it is good that he actually has real back up that is strong, Shinigami's who are trained to fight. Chad and Orihime are not really made to fight, they just accidentally gained powers thanks to Ichigo's presence.

Does make you wonder if other Shinigami or Hollows would have a similar affect on people as Ichigo did on Chad and Orihime. It could be the way the Quincy were created. Though I do not know how you pass down fighting traits. I guess it would be a bloodline thing rather than something you would learn.

So do Arrancar remain in their form or do they change back to Hollow form? Since Ichigo seems to not be able to stay in the form from what you say. Do Vizards and Arrancar have similiar problems?
