I think there was a similar formula like that once, but anyway, I’d like to discuss the possible capabilities of both Byakugan and Sharingan user. I mean, in one of the interviews Kishi mentioned that a child of a Byakugan wielder and a Sharingan wielder ( Hyuga offspring/kinda an Uchiha) would possess Byakugan one and one Sharingan. Unfortunately, we’ve never got to see such a mix eyes, but this thread is meant to speculate what kind of power a shinobi like that would have. Particularly.
How the doujutsu awakening itself would proceed, since Byakugan and Sharingan differ in terms of awakening the former develops through intence stress and feelings while the latter doesn’t have specific requirements and can be seemingly accessed from the earliest age.
What abililies of the Byakugan and Sharingan can become a workable combination together and how powerful the person wielding them can get.
If the Byakugan Sharingan wielder would be inferior to the users of only Sharingan/Byakugan or not according to Madara Uchiha, doujutsu can display their fullest potential only in pair, but he spoke only about a pair of the same doujutsu. In other words, could Make a combo of the different doujutsu cause some problems by the user and lower his level compared to solely Byakugan/solely Sharingan users? Or, on the other hand, could it give some advantages to shinobi that would allow it to gain the edge against either Byakugan or Sharingan user?
The possible drawbacks of Byakugan Sharingan breed together, also based on the drawbacks which Byakugan and Sharingan demonstrated separately.
If the further evolution of the Byakugan Sharingan is still possible. More specifically, it includes the question if Sharingan can evolve into the MS (Mangekyō Sharingan) despite its pair being a different doujutsu. Tenseigan/Rinnegan evolutions are here as well, although their requirements are more specific and thus achievable only in special cases.
