User blog comment:Aizen.sama/Are Espadas, Vasto Lorde(s)?/@comment-2017812-20100420173155

i think ulquiorra is the only vasto lorde as he has two release forms and it has already been shown that grimmjow is an adjuchas, and ichigo's hollow could be a vasto lorde because he had one hollow form when he was fighting his inner hollow and another one when he killed ulquiorra.
