Thank you for posting this!
Okay...
This is exactly why the logic of Naruto/Sasuke being over any juubi jin makes no sense at all (with all due respect), even if the manga says so, the power equation makes no sense. Keep in mind I am arguing from a logical point of view and not necessarily from a feat point of view for this thread (few people understood that).
Then it just means you need more explanation.
Let me illustrate what I mean, you said JJ power > Rikoodu power, glad we agree.
Nope. JJ power > half of Rikodou power, that's what I said. And BTW, this equation is not general, it only goes for JJ Madara and Rikodou Naruto & Sasuke with their specific level of chakra maturity.
To judge how Rikodou Naruto and Sasuke compare to JJ Madara, we've to first compare Madara to Hagoromo (non-JJ version), since he is the one from whom Naruto and Sasuke received their powers. There are two versions of non-JJ Hagoromo i.e. pre-JJ Hagoromo and post-JJ Hagoromo, the latter is significantly stronger than the former despite having the same powers due to a much more powerful chakra.
Post-JJ Hagoromo said that Madara was attempting to gain Kaguya's power. But after he obtained Kaguya's power, we saw that he was quite inferior to her. Similarly, Hagoromo implied that Madara has gained a power close to mine when he had one Rinnegan, which means that after gaining the second Rinnegan, technically Madara should be equal to Hagoromo as per assumptions. But just like how he was weaker than Kaguya after obtaining her complete set of powers, he was also weaker than post-JJ Hagoromo after acquiring the same powers as him. If anything, he should be on pre-JJ Hagoromo's level, who was significantly weaker.
That also makes sense from a logical perspective. Pre-JJ Hagoromo had Rinnegan+RSM whereas 2R Madara had only the Rinnegan. Being a JJ on top of that (which makes him 2R JJ Madara) just granted him the additional boost of RSM, which logically puts him on par with non-JJ Hagoromo (pre-JJ version).
After acquiring the Shinju however (which makes him 3 eye Madara), he got the boost from the Shinju's chakra which presumably puts him close to post-JJ Hagoromo's level, stronger than pre-JJ Hagoromo. JJ Hagoromo is obviously far stronger than any version of Madara to date.
Therefore,
JJ Hagoromo >
Post-JJ Hagoromo = 3 eye Madara > Pre-JJ Hagoromo =
2R JJ Madara
Adult Naruto and Sasuke have fully matured Rikodou power, which is essentially half of post-JJ Hagoromo's power. Which means Adult Naruto (RSM only) and Sasuke (Rinnegan only) individually are = 1/2 3 eye Madara. And since we're talking about JJ Madara w/o Shinju, therefore, Adult Naruto (RSM only) and Sasuke (Rinnegan only) are > 1/2 2R JJ Madara.
Then you said Half of Rikodou power + Ems/Kyuubi > JJ power, now here is where this scheme makes no sense (including if Kishi himself says so, because you can't make 2 + 2 = 3 no matter how hard you try),
There was never an equality, but an inequality.
As established above, Adult RSM-only Naruto and Rinnegan-only Sasuke = 1/2 3 eye Madara. Add Kurama and EMS respectively, and their combined power surge enough to put them individually on 3 eye Madara's level. They not only add more power to Naruto and Sasuke, but they actually combine together with their existing powers making all of those powers stronger as well due to a resulting increase in the power of chakra.
That's why Adult Naruto = Adult Sasuke = 3 eye Madara > JJ Madara individually (in power). And note that this is theoretical. By feats, Naruto and Sasuke are even stronger.
you are assuming that both juubito and juudara lack anything else other than the juubis power.
No, I'm not assuming that.
JJ Madara has the juubi power which is by it self > half of Rikodou power, but he also has at the very least the rinnegan, which is superior to kurama or ems.
No, that's false. Juubi's power is NOT > half of Rikodou power. Juubi's power is just Rikodou Senjutsu = RSM = Naruto's half of Rikodou power. And the Rinnegan = Sasuke's half of Rikodou power. Which means JJ+Rinnegan > half of Rikodou power = JJ = Rinnegan. And that's also theoretical. By portrayal, Rinnegan Madara < Teen Rinnegan Sasuke < JJ Madara < Adult Sasuke.
Let's also factor in the fact that by exact definition both Juubito and Juudara have Narutos exact same powers (aside from the individual bijuu abilities like roshis lava) but instead theirs is powered by the juubi + their own massive chakra.
Yes, they're equivalent, but not exactly equal.
In short the juubis jin have not only the juubis power which is > half of the sages give away power, but also superior ad ons like the rinnegan (and bigger bijuu source) when compared to either of the two.
That's false as addressed above.
And that's why Sasuke and Naruto being > any juubis jin makes no sense to me, even if the manga says so. Kishi didn't follow the correct algorithm.
It does, bro. Naruto and Sasuke did not just have half of Rikodou's power which is superior to Madara's power, they had the EMS and Kurama boost as well.
