[Spoilers] Idk my only explanation...

[ShadowBandit]

For me, the only explanation for Madara being able to use all these justus, survive all this damage. It has to be some form of Izangai, he's able to heal his wounds, deflect attacks, and summon the susanno because he's able to turn his dreams into reality. Thats why he keeps closing his eyes, to access the Izangi power, maybe from the stockpile of eyes he has back at his base.

Idk, farfetched I know. But Kishi has some explaining to do about Madara.

For survivng as long as he has, that is.

Itachi could do susanoo without eyes as well.

Oh well... The Jutsu of Creation uses Yin and Yang Energy, and Madara got both energies.

It's logical to think that he used some variation of this jutsu (being Izanagi one of the possible answers).

The jutsu of creation isn't used with Doujutsu as far as we know, it only needs yin and yang energy.

So you might be right.

Kishi, give us a hell good explanation for Madara's spamming in chapter 658 so that we can start believing again in you.
