whats up with Sasuke’s eye when him and naruto fight?

he’s still developing the curse. the other ones fully developed theirs and can spread it throughout their bodies. and it turns his eye yellow bc he has the sharingan activated.

Naruto Sasuke Eye

That’s just a sign that Sasuke has started being able to transform to the cursed seal’s level two.

Sasuke’s eye is yellow, because that’s the original eye-color of a cursed seal user. However, Sasuke can change that eye color by using sharingan. Therefore, that that moment Sasuke wasn’t using his sharingan, showing the natural eye of the cursed seal.

None of the other cursed-marked characters have that. As I said earlier Sasuke had yellow eye because it was a natural sign signifying that he begun his second level of his cursed-seal. Those other characters have already gone through that beginning level-two process a long time ago, although the manga or anime doesn’t show that. Because they get so exhausted every time they enter level two (currently), you can see that their bodies were quickly being devoured by the cursed seal due to their long acquaintanceship with it.

Sasuke clarifies that at some point in the fight.

His sharingan was being influenced by the curse mark.

Also notice the beast forms of the sound ninja’s eyes, Sasuke was using the power from his beast but he didn’t use a lot. That’s why one eye was dark.

when does this fight happen? i believe, when sasuke and naruto fight, sasuke turns into his second form, where the curse mark consumes him. the reason why the curse mark is sometimes only on one side of his head is because he is in a stage where he is using only a portion of the marks power. when uses its full power it covers up his body and he turns into another form.

Anko has managed to avoid using it’s powers.

Sasuke wants more power, he strives to become stronger, thus activating the mark to such an extent.

sasuke has a special ability that alows him to see better and copy others moves but in order to improve his eyes abilities he has to killl his closes friend thus the fight occurs but he believes he can find another way therefore he side with ichimaru

He’s Special?
