Naruto is the younger brother who has inherited the Sage's body/spiritual chakra.

It's just a battle from long ago, the one that created hatred. It's always the same.
Y son vs O son -> Hashirama vs Madara -> Naruto vs Sasuke.
Hashirama got the spiritual energy allowing him to make wood, possibly creating life.
Madara received MS(first of his clan) and first ever to achieve EMS.
Naruto currently has the cloak, longtivity and insane chakra.
Sasuke currently has MS and crazy eye techniques and is currently awaiting to use his EMS.
If this keeps up, Possibly to be synced with the Demonic Statue you might need the Rinnegan and since Madara only took one, he might combine Sasukes EMS with the other Rinnegan and sync him with the statue.
....It's all a giant DeJa Vu....
