How Could Kabuto EDO TENSEIed Madara since he had no DNA?

[JaffaTalk]

Obito should have wrapped in moulds Madara's body in some safe place anyway, so HOW could Kabuto dare to obtain it?

Or may be there's an another way to perform Edo Tensei, since Kabuto, while revealing it to Obito, stated that It's a former method....:scorps:

Black Zetsu? Who cares, it happened.

 

[~Puppet Master~]

I'm pretty sure Madara's body was kept for Rinne Tensei, Kabuto must've found it.

Kabuto has got a detective fashion...=D

orochimaru probably just stole some dna

Oro has his ways of obtaining these things. It is more likely that he got it than Kabuto.
There is the possibility that Black Zetsu contains Madara's DNA.
It is entirely possible that they got the DNA from Nagato's Rinnegan because it is Madara/Izuna's original eye

Because Kishi says so, he does what he wants because it's his own story.
