caus i think itachi would winxdxdxdxd
i would say itachi would win without a doubt if he really wanted to kill naruto... but considering what naruto stands for, itachi wouldnt kill him because him and itachi have a similar goal and that is to protect the leaf village and sasuke. so the two of them fighting it out to the death is highly unlikely. so in that case it would still be itachi who would win. naruto still struggles with genjutsu's as we saw when he fought itachi when he just wanted to talk to naruto. if it came down to an all out battle to the death, itachi has the tsukyomi, sharingan at a high level, a great amount of fighting experience/training, the ability to turn into to crows to avoid damage and or strike back, the amaterasu, and most importantly the susano. where as naruto has shadow clones, rasengan, raseng-shuriken,4-8 tails mode, and nine tails cloak mode, and finally sage mode. in the end itachi could defeat naruto, naruto may have defeated pain but pain didnt have the susano.
