kakashi never used his mangekyou sharingan in part one of naruto,WHY

[amsy]

it had came to my attention that kakashi awoke his mangekyou sharingan immediately after piercing Rin with the raikiri in the chest before even the begining of the series but yet in the part one of the series he let uchiha itachi torment him so greatly that he was useless for days while in reality he could have counterd itachi's mangekyou with his,but he didn't.now all of a sudden we saw a young kakashi killing his best freind and awakening the thing but never actually uses it untile the start of the 2nd part of naruto,i think that didn't fit with story of kakashi as a whole in the anime of both naruto and naruto shippudden alike,so what do you think guys??:D:D:D

1. He could hardly handle the regular Sharingan
2. He didn't get into any real SERIOUS fights except for Zabuza


Only reasons I can think of.

[zesto]

because he didn't have it simple, the eye needs to be upgraded by entering a serious fight or witnessing something serious/bring hatred towards you

[AP2k]

He probably didn't have the chakra, he could only use chidori three times a day.

[BelphaZar]

yeah kishi has some explanations to do im sure will tell us.

This. And you saw what using it on Deidara in part 2 did to him.

[Nazivon]

I agree with AP2k. Maybe he didn't had enough stamina.

[‡Mudo‡]

How can Kamui counter Tsukuyomi?

[theRPGdude]

He would be dead in the floor.

Way to fail

[Champ]

Common sense once Kakashi unlocked MS he fainted and forgot, so he obviously needed another traumatic experience to re awaken it

[stinkey]

because the sky is so high and no one knows why

[amsy]

I agree with AP2k. Maybe he didn't had enough stamina.

that is true,considering that he was not an uchiha,afterall the real owner of the eyes made full use of them from the begining

[Sephy100]

He needed more chakra control and his stamina is sub-par. That timeskip made everyone get better so that's most likely the reason.

[Kingsigel]

Its because he could not control it, When he summoned it vs Deidra it took a while to activate it and in the other fights he went right into it. Also the two eyes where by each other only an Uchiha can really control the optical power like that.

exactly it's like sasuke who awakened his tomoe sharingan at like 7 when itachi was running away from massacre; he thought it was all a dream and because of tsukuyomi he got mind f***** so badly that he forgot he had it so either kakashi forgot or it takes too much stamina to use

[Kingsigel]

It was neither one of the answer you just suggested. He could not control it what tramatic experience happened when they resucued the one tails host. Nothing at all, and his stamina has been the same the whole time they are at their peak. If anything you all have said was valid why didnt Guy just do the tiger strike before why wait until that one fight.

[★The Shogun]

it was just like when itachi wiped out the uchiha clan. sasuke and kakashi were having serious stress and was exhausted when their sharingans awakened so then it would take time to awaken it. Kakashi during the time skip and sasuke during fight with haku

[KGB Kakuzu]

Because Kakashi mentioned during the Deidara chase that he had a new eye technique then I am assuming the fact that he passes out right after it awakens probably means he doesn't recall it ever happening! And he has never had extreme chakra reserves untill the recent chapter (due to fighting one of the main antagonists )

[KingHashirama]

He could barerly use normal sharingan and fight for long time..

[Staarkk]

He was unaware of its activation, can't you see he knocked out right after he awakened it?

[amsy]

you are all probably right,thanks for your opinions

[KGB Kakuzu]

you are all probably right,thanks for your opinions

No problem! That's why the base is here :D

Such confidence, such tenacity.
such failure.

That was my best guess when they started questioning why he didn't use it in part one.
