so after reading all the theories on who tobi is i was thinking, they all have some strong evidence going for them, is kishi gonna have to go back and tight up all the loose ends of evidence.
i think that the reason hyugas cant see tobi's face is because tobi's mask is actually a wood style tech. i say this because he can use both sharingan and rinnengan, anyways since its chrakra it acts as a shield IDK its what i think:shrug:
