Hold on guys! Let's review this matter with a little more rationality here shall we?
Kakashi Hatake:
1. He can use Kamui at least of 6 times during a battle and still have enough chakra for another Kamui. Kamui requires a lot of chakra to be performed and iThink Kakashi has come a long way since the 1st time he used it.
2. Kamui's accuracy is pinpoint, able to warp a fast moving needle launched by Pain.
3. He can use Kamui in rapid succession (twice or thrice iForgot) as seen against Sasuke's Susanoo Arrows. He was still fit for combat after that.
To tell you the truth guys, Kakashi's only chance of winning against the 3 Sannin is through his Kamui.
iDon't think his dogs or Thousand Years of Pain will help him out..
In conclusion:
Kakashi is a natural genius right?
He needs to come up with a plan to beat the 3 Sannins fast and effectively before the battle drags out far too long.
He needs to use Kamui to end the battle fast IMO.
He has 6 tries or more to end it.
Obviously the Sannins won't just sit there and get their heads warped away right?
This is where he needs to rely on his speed (4.5/5) which is on par with J-Man & Oro, coupled with his Sharingan (predict movements especially) & Kamui, there may be an ounce of hope for Kakashi.
What do you think?
1) No he stated the most he can use Kamui was 3 times and has to be hospitalize for a week or two (can't remeber which but most likely 2 weeks since Yamato had to take over for him).
2)Kakashi has gotten better with his targeting with Kamui but the needle Pain threw was going in a straight line and the Sharingan allowed Kakashi to see it so he could use it accordingly.
3) It was 1 arrow that Kakashi teleported, Sasuke was about to shoot a 2nd one but his Sasunoo ran out then Sakura was about to kill Sasuke until she chickened out. Kakashi was still to weak after Kamui usage and couldn't make it in time but Naruto speed was great enough to save Sakura and Kakashi praised Naruto's speed being greater than his.
Yes Kakashi is a genius but Orochimaru was the "Genius" in his group and lived up to it until he was sealed by Itachi. Jiraiya is the Strongest Sannin and it was even stated that Akatsuki didn't go after Naruto in the 2 1/2 year time skip because he was with Jiraiya. The Sannins got way more battle experiences, chakra, stronger summons and have knowledge on Kakashi and wouldn't take him lightly. ( Ororchimaru doesn't know about Kamui but if caught might be able to stretch his body then shed his skin to escape. Kakashi would do better if he had a larger chakra reserve.
Tsunades speed is 3.5 while Kakshi is 4.5
Clearly Kakahi is faster than her and yes!
It would be interesting!
Lets take in the fact that when he's running at her she can punch the floor to disrupt his running then attack him lol She has battle experience and most likely had to fight ninjas faster than her lol
