Well from all replies I have seen some people are writing somehow things that can be compared to an atrocity, maybe its lack of knowledge from Naruto series/manga or they watch it in Japanese. Well let’s do this by topics.
1st Topic: Pain can’t perform a “Katon”, at some point those persons were right, we’ve never seen a fire spell from Nagato , but THIS IS PATHETIC, if it wasn’t showed at the series, doesn’t mean he can’t! Those who have Rinnegan control ALL the 5 elements, including Yin-Yang. For those who think I’m insane, my tip: Watch pain story again, and they you’ll see Nagato using a “Fuuton”.
Btw, Deva was able to cast water jutsus and I’m sure it wasn’t because Yahiko managed to control it.
So people said that Nagato jutsus would have been useless against Kabuto water pool, THAT’S PATHETIC, and he doesn’t need to control the all the nature types… 2 single words: SHINRA TENSEI! If you laugh at this… you must commit suicide. ST repulses and pushes and matter (I meant to teach you guys some Physics) so if water isn’t matter I think I’m leaving in the wrong world. (Same applies to BT) Basically, it’s useless.
If taught you some Physics, I’m happy, because right now you know that the same applies to CT, if his “super-counter” to Nagato casts was useless to ST and BT that turns Kabuto vulnerable to CT. If 6-tails wasn’t able to resist to it Kabuto isn’t either, so his only option is damaging the Sphere of Gravity like Naruto and Bee did. Although is CT requires a lot of effort but we also know that in the short space of time between 8-tails and Seal restoration (which in my opinion is relatively small) Deva was able to use ST as well as BT, even though we’d probably shut down the other paths like with the ST that he used to destroy Konoha, I’m sure after CT caste he would restore them again. Summary: While Kabuto struggles to destroy the Sphere he is vulnerable to Pain’s attacks, in worst case scenario Kabuto dies.
(I think it’s pretty much impossible to Kabuto to resist the gravity push even though I made my thought above as an “if”, if he dodged that, what he would do?)
2nd Topic: Manda II, she’s a beast, way bigger than the entire summons that thus far Pain showed us. I’m not now teaching philosophy to you guys but “Size doesn’t mean anything” and I do agree, The Dog is somehow immortal and more you hit them, more heads/dogs spawn, but with Manda II size is somehow hard to imagine lots of Dogs killing it all alone. So Nagato’s show time! Nagato can summon a lot of Animals, so I’m sure he could over with that stupid snake! Killing the animal path is the only solution for Kabuto though it sounds impossible to me as Ninjutsu and Taijutsu don’t work, going Taijutsu is proved to be a very dangerous because of Human Path and we know that Kabuto is a smart guy so he’d figure out that Pain’s weakness is actually Genjutsus. Could Pain avoid Tayuya genjutsu? I’m sure he could and one more time it relies on the Physics, Sound spreads through air, and air molecules do have mass, so Deva could actually use is ST in order to repulse Kabuto’s genjutsu.
Ok that’s all, I’m not a Nagato fanboy, to be honest I do like way better Kabuto since he is such a persistent bug xd! But Nagato is the perfect counter for Kabuto ah! And he said that he couldn’t defeat a Rinnegan… And we know that Nagato knows a lot more of Rinnegan than Tobi so I must give the edge to Nagato.
