Why are you adding him a white getsuga tenshou? he used the black-red one didnt he? Since it's said that Ichigo is only using it from his Hollow form.
There shouldn't be a new Hollow form on him. We didnt saw anything nearly like that yet. He is the Hollow inside Ichigo and the mask is for controlling him like the vizards. Everything containing Hollow transforms and new attacks belong to Ichigo.
