Itachi knows who Tobi really is!

[Ndias17]

itachi doesnt truely know who he is, all he knows is that tobi hated the uchiha clan and planned on getting revenge on them. tobi and itachi worked together during the uchiha clan massacre,so after itachi made the deal that sasuke was the only one to be spared, he knew that later on tobi would try to approach sasuke and get him to destroy konoha which is why itachi implanted amaterasu into sasukes eyes if he were to see tobis sharingan

Lol Kisame knew who Tobi was not Itachi

::sighs:: it was stated in literal black and white why Sasuke's MS went off.....go back and read it...

 

[Prime Rib]

actually it was meant to trigger when tobi eyes are showed not the face

 

[swa]

It was to go off at the sight of a Sharingan, because Itachi knew Tobi would go for Sasuke before anyone else, and he knew Tobi had a Sharingan. Unless Tobi is Madara, Itachi is still under the impression that Tobi=Madara because when Naruto told Edo Itachi what Sasuke was doing he was like, "So Madara told you about the Uchiha Incident".

yeah..!! right..

Kisame also referred to Tobi as Madara when Tobi took his mask off.

Doesn't mean that's who he is, I'm jus saying.

He is Obito,not because of the hair but because he has on his right eye the same power as Kamui that developed diferently.
