I don't believe White is VL and never be one, basically you will became a VL through consumed other Hollows and keep maintain your intelligence. Also, there's a stage that you have to pass, from Gillian to Adjuchas then you became VL. I read the definition of VL on databook its describe - "Adjuchas that have evolved even further by consuming more of their kind. Roughly the same size as a human. It is said their combat ability is superior to a Soul Reaper captain." - MASKED (Viz Version), Terms Explanation p.252. What I say, a VL Hollow formed by natural ways. Except that, in the UNMASKED the term that Kubo give to masked-horned-long haired Ichigo is just Kanzen Horouka or Perfect Hollow, not 'Vasto Lorde' form
.....
Logically, if Aizen could freely developed a VL Hollow, he must didn't have to command to search VL throughout Hueco Mundo to be Arrancarized. I still believe White is a special Hollow, created through experiment and has a certain goals. So, no wonder if he have Cero, Sonido etc that similar to Menos class Hollow. I agree White now is completely in different form from he was. He is merged with Ichigo Shinigami power and becoming his Zanpakuto, proved with his appearance as a opposite color of Ichigo. The bad news is never exist a Zanpakuto merged with a Hollow, even he have wild and stronger will than his master. I don't know what happen with Visored Zanpakuto, but in Ichigo case must be different than what Visored experienced. We can call White a VL but still wrong to me if we call Ichigo full Hollowfication is VL.
....
The problem is when people called that because its appearance only, when Ichigo become a Lizard-like Hollow, he already can fired a Cero. Do you think he was a Gillian or Adjuchas back then? And when he goes berserk Hollowfication against Ulquiorra, you immediately call he is a Vasto Lorde without any explanation. I never see term Vasto Lorde along Ichigo Hollowfication neither on databook, manga or anime. I think it's just when some fan-artist give a catchphrase Vasto Lorde to their art, that's when this all begin. I don't give a damn if people name that cause it's just a name, all have their reason but I still insist White is not VL Hollow and Ichigo hellknight is not VL form. Otherwise, Kubo give some damn clear explanation.
