Wow, it's almost like SPSM isn't what causes the sage marks on the back. Incredible.

That power is the juubi’ own chakra, also called rikudo senjutsu. It’s the exact power both obito and madara gained after sealing each biju(or their fragmented power) inside of the gedo statue, and then into themselves. This made them become juubi jinchuriki which granted them the power to achieve rikudo sagehood through transformation. Naruto was also consider a juubi jinchuriki because with cooperation of those 9 fragments he achieved the same power, juubi chakra aka rikudo senjutsu.
