One possibility is that he's the one behind the attempted kidnapping of Hinata when she was a child, and his eyes actually belonged to Hiashi. Maybe he needs the eyes of a main branch Hyuga for his goal. As I speculated in the other thread, it's possible that like Naruto and Sasuke, he constitutes one of the two halves of Hamura's descendants, and in obtaining a "pure" Byakugan he hopes to awaken Hamura's power.

At any rate, it makes the most sense if this villain would comparable to the combined might of Naruto and Sasuke. If he's the reincarnation/transmigrant of Hamura, that might well be the case.

I'm really curious for new details, now.
