It has been stated before that Kakashi doesn't have the natural power of an Uchiha body despite having sharingan. I forgot where but I do remember it being said, thus the exhaustion. It has nothing to do with not having a mastery over the technique or the eye being alien to his body.

Their eyes bleed when using susanoo or amaterasu, I don't believe we have seen them bleed during just a mangekyo. His ability is not as difficult to use as amaterasu or susanoo, because it is a simple mangekyo which is the lowest level of uchiha epic. It has also been stated that once they unlock mangekyo their vision deteriorates until blindness, I doubt Kakashi giong blind will have a significant effect on the story though.

I hope Sasuke goes blind soon. He has been using susanoo non stop for the third fight now, on top of a crap load of amaterasu.

he is

to carry out this discussion.. what do you guys think itachi gave naruto???

prolly 1 of those weapons he was using in susanoo mode

good call. I'm thinking along the similar lines... either that or something crazy that I won't even bother mentioning XD

no shit. I just hope it happens soon. You state both the wrong and the obvious way to much XD

Or it could also be something to help prevent the sharingan to take control of the nine tails.

itachi was a fucking beast there is no telling what he put into naruto

hell it could even be some sort of gentsu that only acts when sasuke uses shargian on naruto to show sasuke some truth of itachi what he was really about or a going away message and to help break him from madara, he knew madara would go for him hence the amutrseu this could be abother anti madara step

itachi cared more for sasuke then the village its self i doubt he would give naruto a power to kill sasuke

itachi probably just gave naruto something that weakens sasukes attacks


and about itachi being a beast....iirc itachi was much stronger than sasuke and when they fought itachi sorta let him win.....which makes me hate sasuke even more


btw as far as i can remember, kakashi has used mangekyo more than sasuke and he still has his sight where sasuke is going blind

DEFINITELY agree. I don't think that whatever itachi gave naruto was a WEAPON... I think it would be more like a shield or some sort of defense mechanism.

iso when naruto learns that minato (4th hokage) was his dad

wanna check that out again
