It seems that the only way is to show a chronological order.
I will start with the Kakuzu bow until I end up in the war.
Well, we see kakashi surprising Kakuzu (Yes, Kakuzu was on his back),
but Hidan and the others don't even see Kakashi's trail, and he was using raikiri, meaning no one saw or reacted to Kakashi with raikiri.
At physical speed, Hidan accompanied Kakashi, and he is MHS+ just like Kakashi, but previously Hidan did not see him visually and much less physically.
Resumo, neither of them got over the reaction.
<Hidan> Accompanied Kakashi at physical speed (MHS +) and had no reaction to Kakashi with raikiri
(Now let's go to the arch of the dome of the 5 kages.)
Chapter 484: Sasuke MS vs Kakashi fight begins.
the brief fight ends in chapter 487. I don't need to narrate much here, because the only thing that really matters is that Kakashi didn't have a physical reaction to Sasuke's arrow, but just visual with Kamui.
In chapter 488, everyone goes back to Konoha, including Karin
In chapter 489, ''
the prep for war begins. There all the shinobi are gathered. ''
From chapter 490 to 514, they are Obito and Kabuto revealing the akatsuki edos, flashblacks of Invasion of the kyuubi in Konoha, konan vs Obito and Guy vs Kisame.
In chapter 515,
the battalions are already divided, and even Kakashi is a leader of a battalion
You may be wondering why I showed you these chapters. Well, from chapter 488, in which Kakashi and the others go to Konoha, until chapter 515 that the battalions are already formed, there is nothing more than the 5 kages gathering forces and Obito and Kabuto preparing the Edos Tensei and the white zetsus . Anyway, what I mean is that the shinobi came together for the war, that is, everyone was very busy with the preparations. And that supports what I always said here that Kakashi, like all the others who were in the alliance, he is in the same shape as before the war.
And a good example that sustains Kakashi being in the same shape is the fact that he fights against Zabuza edo.
In chapter 521,
Kakashi from the war again accompanies Zabuza in the edo version, and in
chapter 522 too.
As far as I know Zabuza is MHS +.
Zabuza
Speed: Massively Hypersonic+ (Kept up with Kakashi)
Anyway, let's recap?
* Kakashi's fight against Kakuzu and Hidan: He accompanied Hidan, both MHS +, and no one had a reaction to Kakashi with raikiri.
* Kakashi from the war against Zabuza: He accompanied Zabuza, another MHS +.
Conclusion: Pre-war Kakashi was accompanied by MHS + shinobi, and Kakashi from the war is accompanied by Zabuza, who is also MHS +.
What everyone has unusual about Kakashi is that no one was able to accompany him with the raikiri, with the exception of the Guy with 6 gates.
