Umm I don't think he would come back with the Juubi's power
Obito still had his Truth Seeking Balls despite no longer being a jinchuriki.
He wouldnt be Shinju madara
They would come back in their current state.
Like Nagato and Hiruzen.
Even Madara came back with the rinnegan.
Madara's last state was a blind oldman
He got fixed by Kabuto as stated in the manga.. But since he came back alive and surpassed his prime
The the point of becoming the Juubi jin. He would revive in that state.. like all the other edos did.
Madara already came back alive for 2 tines but he was about to revive SHINJU MAdara
With edo tensei... Lmao he would **** things up badly.
