No, Itachi is dead now and why would he fight Lee?
Naruto did fight itachi when he was a kid but barely. But now he is dead so it ain gnna b a real fight. :P
No, Sakura does not. She does however, appear in a battle against a fake itachi.
yes [warning spoiler sasuke kills itachi in shippuden]
They never fought.
saskue and itachi fight, and in the end itachi died, in order to save and protect his younger brother
Pain
Yes by Itachi dying in the hand of Sasuke it awaken the Mankeyo Sharingan.
Itachi and Pain never end up fighting each other.
Not once has Itachi interacted with Sakura, she's only seen him once and didn't do anything to fight him.. All she did was sit and watch the fight, so no.. Itachi did not save Sakura from falling, though I have no idea where she's fallen and where it even suggests Itachi was involved with saving her.
They fight in manga naruto in chapter 141-142
Itachi did not fight with Guy instead he fought Kakashi somewhere in 80+.
No. Deidara dies before they could even fight. If Kabuto revived Itachi in part 3 then maybe they could have had an epic battle. (Deidara gets revived by Kabuto)
