dude your waaaaaaaaaay off there man zetzu has nothing to do with sasukes dad none wuts so ever zetzu always followed tobi not itachi theres no way in hell that zetzu would even help fukazu he is not powerful enough zetzu only recorded fights up now to now he is fighting so that theory is competely lame dude explain how obito right side body was crushed and explain why tobis right side of his body has zetzu huh that means zetzu connecting part of his own body to help obito and maybe the real madara ordered him to do it theres still a big whole with madara, tobi, and obito well its my opinning anyways but as i said before theres a possibility that is not obito and a possibility that it is and maybe just maybe izuna as well
