Hope some fans read this and put out some comments - refer to when Hitsugaya explained to Ichigo what is Vasto Lorde and is he talking about the 10 Espada or just another Hollow Being of higher capabilities then the 10. Some fans even argue that from all the 10 Espada only Ulquiorra is of a Vasto Lorde qualities - so this is quite confusing. If Stark can matched Ukitake and Kyoraku, with what they fans all are telling then 1 (one) Vasto Lorde being is maybe equaled to 4 captain class shinigami same as like Aizen slashing 4 captain class shinigami at once.
I just find this facts is rather confusing. Could some one lend their thoughts on this one?
