Oh. My. God. I just found this section. My life is now complete!

they all die at end ^^

soo anyways.
back to topic
what should we talk about O_O.

Kakashi's sharingan and if it contains the same qualities as, say, another persons. Keep in mind that kakashi got his sharingan by means of ANOTHER uchiha. So can Kakashi go blind from using the mangekyou?

If I remember correctly, in the past chapters Kakashi mentioned that using the mangekyou only caused him extreme exhaustion - I don't think anything about him going blind was mentioned, we never know though.

yeah but the extreme exhaustion is only because his natural powers aren't as epic as an uchiha.

well itachi asked him how bad his eye sight is when they met

so it would be better to speculate that he WILL go blind sooner or later although it's impossible to say for sure

Not entirely correct. His body wasn't MEANT to hold the sharingan, it's not to say that kakashi's body isn't as epic... it's just not as good of a fit for an uchiha eyeballz



ALSO! As we've seen with amazing feats from sasuke and itachi... their eyes BLEED (quite often) when they use the mangekyou. However, we have yet to see kakashi's eye cause anything more than exhaustion. So my question to you is... Is kakashi's ability as difficult to use as say Amaterasu or Susanoo (or however you spell it)? And does just having the mangekyou activated, but not using any abilities with it cause blindness? Continue!

when itachi was telling sasuke about madara he said that once you unlock mangekyou your eyes detoriorate slowly (inevitably lose their light) and using techniques hastens it.
the fact that kakashi knows about itachi's eye sight says that he suffers from it himself.
he would have no way of knowing whether mangekyou makes you blind or not because he doesn't know about the uchiha shrine and their secrets.
also, the only time itachi/sasuke bleed is when they use amaterasu, so i think it's safe to say that the bleeding is a side effect of amaterasu and not sharingan.
if you see the first time itachi unleashes amaterasu he bleeds before he feels the side effects or any flames come out.
i think he already is suffering from it, but not that much because he doesn't use it very much at all.
even when he uses it he activates the technique and goes right back into regular sharingan where itachi and sasuke keep it on through out the whole battle.
as for the transplant.. if i remember correctly you can only activate eternal sharingan with your blood uchiha brother's eyes so i don't think kakashi has it.
