He is a re-incarnate, and getting some of Hag's chakra reacted with his own and helped him awaken SPSM and his very own Six Paths chakra(which by no means is the same quantity or strength as Hagoromo's because Madara with the rinnegan had awakened Six Paths chakra yet he wasn't anywhere near as strong as Hagoromo period) he like Sasuke was able to awaken their own Six Paths chakra that their own bodies generate, the chakra that Hagoromo gifted them can only be regenerated by him therefor they do not have his chakra anymore after VOTE2. This is why I think they were so OP in the 4th War, with Sasuke needing to steal all 9 tailed beasts chakra to fight SPSM Kurama Cloak Naruto in an even battle.
