M: Vasto Lordes aren't Arrancar. They are the strongest Menos Grande Hollows.

Xilinoc: While it is true that it has never been stated that Zangetsu's full Hollow form is a Vasto Lordes, thus it can not be confirmed that is is, I believe that Kmbfsu11k's assumption is a reasonable one. Vasto Lordes are the strongest Hollows and are about the size of a human. That definitely sounds like Zangetsu's full Hollow form. I personally also think that it is a Vasto Lordes.
