I am confident that Edogawa's post effectively counters everything in the following posts, so I will not just rehash the same points. However, I have a few specific points to bring up in response, in addition to Edogawa's great counterargument.
When did Human path do anything to Jiraiya in SM?
Hidan overwhelmed Asuma and was on Par with Kakashi both of which are loads faster than the Jounin Human path had to ambush from the shadows.
I was referring to the page where Human Path blocked Jiraiya's punch. Also, the other Pain bodies were easily keeping up with Jiraiya and Naruto. At the very least, Human Path alone is a ninja who has been shown to blitz Jonin, which Asuma is, and keep up with high level shinobi such as Naruto in Sage Mode and Jiraiya. By itself, that should support that Human Path is on the level of Hidan, if not far beyond.
I am curious how you both will attempt to answer the idea that Human Path has his own speed, and it is not simply the speed proportional to the chakra Nagato puts into the bodies. I do not need to discuss the speed of Nagato himself or the other paths as Human Path is well fast enough from just what we have seen. Regardless, why would you take the stance that any of Pain's bodies have a different level of speed to one another? Is there support from the manga that says such?
No. Nagato wouldn't be able to dodge them with ease if he were to fight like Hidan. Nagato won't be able to land attacks as well on Yugito if he fights with Hidan's scythe.
Its not just about speed. Its about reflexes, taijutsu, weapons specialization, dexterity, etc. which Hidan is skilled at. Comparing them to how they would fair against similar opponents is like apples & pears. If you use only speed as a factor which includes attack speed, reflexes, etc. then I would give it to Hidan.
I am quite astounded that you believe Hidan is remotely near such high level shinobi's speed when he has only shown being on the level of Kakashi during that time, and neither shinobi vastly out-sped the other. Meanwhile, everything that Edogawa stated is true and Nagato was able to keep up with shinobi who were on A and Minato's level of speed.
It was stated nagato's reaction speed improved after he got his real body. You cant take that for human path reflexes , human gets beheaded .
Out of curiosity, where was this fact stated in the manga? I do not recall ever reading this. Perhaps you are referring to when Nagato was resurrected with Edo Tensei and was restored to his original form before he was bound by Gedo Mazo (though, admittedly he was still a cripple)?
I can perceive no reason why the chakra Nagato puts into his paths would be significantly slower than his own speed, and if you disagree I would appreciate if you could support it; despite that, Human Path and the other Paths of Pain have demonstrated enough speed that can stand on their own merits without relying on Nagato's speed.
Yeah because he was talking about his footspeed rigggggggght??? Learn to decipher simple words, and end your mindless rambling. He was *****ing asuma up even while dodging the extremely fast kagemane, shikamaru himself said he cannot keep up with hidan's speed and you can see him sweating heavily. Human path doesnt come close , he ambushed , which anyone can do , hidan was overwhelming a jounin level shinobi while evading the kagemane which someone as fast as kakuzu had trouble evading. Hidan might be the slowest in attacking but his attacks have a tricky manner of hitting his targets considering he beat yugito and chiriku who were said to be extremely strong , while the latter being beaten was incomprehensible by asuma. You're thinking hidan's body is just immortal, lmao you're wrong, not even once was he injured without the kagemane restricting his movements. Manga says he is invulnerable, which means physical attacks dont work against him. It only worked because shikamaru used his yin release : kagemane to hold neutralize his power as the databook says he has "black power" and you know what that means, yin yang.
I apologize if my points were not clear in my posts. You all seem to be very desperately caught up about Human Path and Hidan's speed in comparison to each other, but I did not mean to suggest Human Path would be able to vastly out-speed Hidan. Although I do believe that to be the case, as Nagato had kept up with some of the fastest characters in the manga while Hidan only matched some Jonin at best (if he were much faster, he could have blitzed them which never happened), my arguments are not reliant upon that being the case. I am only saying that, granted that Human Path cannot out-speed Hidan, neither has Hidan displayed the necessary criteria for being as fast as characters along the lines of KCM Naruto. Therefore, Human Path must be at least as fast as Hidan, or, put another way, Hidan, if faster, is not extremely faster.
If the two are even around the same speed, then I stand by the initial argument that Human Path merely needs to touch Hidan in order to kill him, and Human Path, as long as he is anywhere near the speed of Hidan, that is, not completely out-sped in every sense, which is clearly the case, then Human Path should be able to touch Hidan a single time. Further, Hidan would never be able to kill Human Path because he is required to stand still to perform his ritual. Human Path would never stand still and allow Hidan to kill him; he would easily be able to touch Hidan in that time and Hidan has no realistic way of preventing Human Path from touching him.
Thus, I conclude that the only way Hidan could possibly win is if you are able to support the idea that Hidan is much faster. The concept itself poses a great puzzle for me, so are you capable of supporting the idea that Hidan is so much faster than Human Path that he will not allow himself to be even touched? If not, the why do you all still posit so strongly that Hidan would win?
