So, Gillian are Hollows that devoured each other. They are mindless (or overminded), so they don't think rationally. Adjuchas are Gillian that managed to evolve due to superior power of a single Hollow that was a chunk of Gillian. But, how does an Adjuchas evolves into Vasto Lorde? I always thought that Adjuchas becomes a Vasto Lorde by tearing of his mask. But that would make them Arrancar, and even a lowly Hollow can become Arrancar by unmasking himself. Also, 90% of Espada are Vasto Lordes, but, they are Arrancar as well. At the same time. So my question is: what is the difference between Arrancar and Vasto Lorde???
