The next SO6P here are my reasons why
1. SO6P actually DEFEATED the FULL juubi while obito sealed an incomplete juubi in himself
2. Juubi took over obito soooo right now juubi is on a rampage NOT obito...just like how kyuubi used to take over naruto
3. Kyuubi has hinted that the next SO6P will guide them to the right path and he said it will be Naruto
4. Last but not least like I said Naruto will be the next SO6P
I'll bite.
1. Rikudou sealed the Juubi within himself much like Obito sealed it. There is still a noticeable power difference, but power doesn't make or break a character parallel. It is the feats, ideals, and character symbolization (including character relations)
2. This is not necessarily true. Obito still recognized his name and the only thing to confirm is that he has lost his sense of self. His new persona also displays some characteristics that aren't like the Juubi beast we know. There is more going on here.
3. Rikudou never stated they would be the next Sage, only that he will be surpassed. Rikudou stated that one day there will be someone who could lead the Bijuu down the correct path, unlike when they were within him, and that person will show them true power. The true power is hinted to be love, the power that the Younger Son believed in.
4. The most important thing is that being the Younger Son and Obito being a Sage/Anti-Sage does not deny Naruto of his destiny as successor. Like Rikudou, Obito is attempting to be God and has brought unification to the ninja world, but that will die with him like it died with Rikudou. Toward the end of his life, Rikudou believed love to be the answer, and the one who will bring true peace and power will use love as their means.
Naruto will be something greater than the Sage by the end of this. He will be the one that truly surpassed Rikudou, but through the Younger Son's means and philosophy.
