doesnt fit in? he couild beat deidara, kisame with extremely high diff, hidan, possibly sasori and kakuzu
Deidara>>>Kakashi
Kakuzu>>>>Kakashi
Sasori>>>>Kakashi
Kisame>>>>Kakashi
The only person Kakashi might have a chance against is Hidan because Hidan an Idiot.The rest of them would destroy Kakashi with low to mid difficulty.Once Kakuza releases his heart, Kakashi has no way to counter him.Sasori Has literally thousand of puppets at his disposal, but he wouldn't need them because Kakashi doesn't have the phyical strength needed to take on the Third Kazekage's iron sand or deal with Sasori's poison.Kisame doesn't even need an explanation, that's just a joke to even bring Kakashi in the same sentence with Kisame.As for Diedara, I assume you think Kakashi could beat him base off of Kakashi taking Diedara's arm with Kamui.But you must remember, Diedara was only trying to get Kakashi away from naruto.In a fight, Diedara wouldn't be just flying calmly overhead giving Kakashi a chance to used Kamui.Diedara would be attacking with the same amount of force he did when he fought Gaara.ANd unlke Gaara, Kakashi has no defense for Diedara homing bombs.He might be able to used Kamui a few times, but in the end, Deidara has more bombs than Kakashi has the ability to used Kamui.
