[Theory] sage and his brother vs juubi and ancesator Hyūga and uzumaki

[Obítō1]

ok guys this is my first theory so be easy on me pls so here we go

1) we now that kaguya was very powerful and she born 2 children on hogoroma and one his brother
we also know that they fought juubi and the fight goes on like that hogoromo was first juubis jinchuriki and his brother
was well known with his sealing techniques he had byakugan and he died battle with usuing reaper death seal he seals
juubi into hes brother and then died

2)i am shure things go like this kaguya born 2 children hogoromo was gifted with rinnengan and physical power and
his brother byukugan and power of sealing thats how they take down juubi and seal with hogoromo so
hogoromo created uchiha and senju
and his brother Hyūga and uzumaki

sorry guys short but its my first so be easy

His bro probably sealed it into him but who knows, Hagoromo has Rinnegan and can seal

bet the younger brother sealed it resembles the uzumaki sealing

 

[Obítō1]

bet the younger brother sealed it resembles the uzumaki sealing

who knows but its makes sense that he used reaper only kishi knows
