Impossible. He isn't Indra's transmigrant. He might have stronger chakra but it won't be Rinnegan.
I guess if Obito took Mad's DNA, he would have gotten Rinnegan.
Hashirama already died, hence why the Ashura chakra is nonexistant until Naruto was born. Madara was basically Kaguya at that point without the tree. Otherwise Obito would have won already.He would have gotten Indra chakra in him. He probably has Ashura's chakra in him too.
He doesn't need a Rinnegan. His MS alone counters 95% of Rinnegan Jutsu's and infact it counters like 95% of all the Jutsu's in NV.
Just image how powerful Obito would be as a JJ with 2MS
Kamui solos he just needed his other eye back
He doesn't need the Rinnegan, his MS solos. If he had both of his eyes Madara couldn't do anything to him and he would be OP.
Indra wasn't inside madara at that time, he was inside sasuke
Obito Ain't ashura, and if he is, then kakashi is indra
Obito's MS> most of the Rinnegan jutsus
