Man, its a fictional story after all, anything can happen ...sooo bz controling obitos body and saying he'll record their deaths means something else to you? bz and obi not freinds
Many sons betray their fathers LOL, even your sperm betrays you sometimes U_UMadara's sperm (black zetsu) isn't going to betray Madara guys :|
Well, i can and can't be...Guy, don't you know that Kishimoto is not them?
And even so, Kishi already had someone betray Madara. That was Obito. And then BZ took control of him to give Madara his eye.
I'm sorry, it's just too improbable for BZ to turn. He's literally a living manifestation of Madara's will. If he did, Kishi's writing will have been declared inconsistent and shit. Many already think this.
But let me tell you this : What if Naruto did something to BZ with his power , and cut his bond with Madara ? Is this acceptable ?
After all, anything can happen, it's Naruto (OP)
I know lolBZ is madaras will lol
