Re: Madara's "plan" to use Nagato which was Fail anyway
When the reincarnation jutsu is used i believe you are revived in excellent health and full chakra. But also nagato said his power was only a fraction of rhe original sage. That being said Madara might have know something else about the ressurection jutsu.
Also Madara PROBABLY wanted Nagato to bring him back right after he died, BUT Obito rather Nagato bring himself(Obito) back.
Question if Obito is brouht back after death by either Edo or RG will he have Both of his eyes? Alao with hahi DNA shouldnt he had grown his eye back in that left socket?
