You mean, survived the annihilation of the Quincy 200 years ago?

It could well be that Bazz-B will reveal BG9's epithet, like you proposed. Somewhat like Starrk, when he indirectly confirmed Shunsui's guess that Harribel was the 2nd Espada, and indirectly revealed Baraggan as the 2nd Espada.

Cang Du is pretty much like BG9, only that he looks all human and haven't said anything at all yet.
