Re: Kakashi Vs. Akatsuki
Considering this is a IC Kakashi
Konan- Kakashi wins (considering she has no prep)
Hidan- Kakashi wins
Deidara- Kakashi wins Kakashi managed to connect a Kamui onto Deidara's arm when he was first using it. Since then he's managed to train his Kamui speed and accuracy to the point where he can warp away a Susanoo arrow, something Danzo couldn't even dodge.
Lightning affinity also gives him a boost over Deidara's earth affinity.
Itachi- Kakashi loses
Pein- Kakashi loses
Sasori- Kakashi wins. Remember Sasori is stationary when he is controlling the 100 puppets, and his heart thing is really obvious so Kakashi should have no problem Kamuing it away. Kakashi mid-high difficulty since he wont use kamui right off the bat.
Kisame- Not sure in all honesty.
Kakazu- Kakashi wins with extreme difficulty.
A few points.
Kakashi himself said to Naruto how he would've been forced to use the Mangekyou to sort things when they were talking later on after the fight. He wouldn't claim he could do it, if he couldn't in actuality. He seemed to be sure he'd end up at the hospital, but he would've managed to take Kakuzu out with his MS.
He was able to activate his MS instantaneously to blast away the Susano'o arrow sent at him by Sasuke, that too at very close range. Let's not forget that this is the same arrow which caught Danzo, too and would've killed him had he not had Izanagi, which effectively kept him immortal. All in all, Kakuzu was still holding onto Kakashi and was charging his attack. The time window in which Naruto and Yamato intervened with their combo, Kakashi could've used Kamui. The feat against Sasuke proves he's capable of such a thing. And since Kakuzu was standing right there in front of him, he would've had a clear shot at his head.
Also, also, he warped away a missile sent at Choji by Asura Path, when he was himself half buried in rubble. That tells you about his focus and accuracy with Kamui, getting a moving projectile so perfectly when he was at the verge of death himself. Kakuzu was standing riiight there in front of him, stationary, even if he was shooting off a jutsu. Judging from him countering the Susano'o arrow and warping the missile, Kakashi seems quite capable of such a feat (i.e. just blasting Kakuzu's head off with Kamui).
Pein is on another level compared to Kakashi, he did great against him.
Before the Akimichis arrived, Kakashi was actually about to kill both God Realm and Demon Realm. Demon Realm was paralysed by Kakashi's Raibushin, and because God Realm had just used Banshou Tenin he was unable to use any of his gravity powers for another 5 seconds. Not only this, but God Realm was completely unaware of Kakashi's location (as he was hiding within the rubble) and both God Realm's and Demon Realm's back were turned to him. This means that neither Realm would have been able to see where Kakashi was coming from, and being that one was completely paralysed and the other was unable to use his jutsu, they would of had no way of evading Kakashi's surprise attack. We saw that even with Kakuzu (a ninja with far more experience than either Nagato or Kakashi), Kakashi was able to easily sneek up on him without the slightest detection from Kakuzu. I don't see God Realm and Demon Realm being able to detect Kakashi in such a situation. Everything was completely to Kakashi's advantage. Once you break down the facts and not look at it in such a simplistic fashion, you will realize that Kakashi was actually about to solo both Realms completely on his own, before the Akimichis even showed up....without Kamui.....and needing less than half his chakra.....
