He may have given him something, but not Sharingan.
perhaps itachi uchiha gave naruto uzumaki the power to escape the amaterazu
He gave naruto the power to destroy the susano'o
something to free sasuke from mandaras influens my quess is mesage to him with genjutsu + some short of power
in naruto 1,2,3 itachi was 18 and in naruto shippuuden he was about 21 and i dont know kisame's : p but u may find it if u searched at "narutofan.com"
It was Kotoamatsukami, Shisui Uchiha's ultimate genjutsu, set to activate when Itachi's Mangekyo Sharingan was used on Naruto. Knowing that Sasuke would probably implant his eyes into his own, Itachi left one of his crows containing Shisui's eye (the other one was stolen by Danzo), as a means to "protect Konoha". However, this genjutsu was later used on Itachi himself when he attacked Naruto under Kabuto's control, thus freeing him.
Itachi gives Naruto some of his power, though it is yet unknown what exactly the 'power' was.
no one
perhaps itachi uchiha gave naruto uzumaki the power to escape the amaterazu
It was some of Itachi power that can be used against Sasuke. This was Itachi's to make Sasuke change his mind, and do something good for a change ¬.¬' But the power that Itachi gave Naruto has not been reviled yet.
He handed it out before he died
It was more chakra for him to use in the future.
no itachi never caught naruto
Wait and se
It is unknown which powers Itachi gave Naruto. It might be revealed soon as the long-awaited battle Naruto vs Sasuke is about to begin. what itachi gives naruto is uchiha shisui 's eye. shishui 's eye is very powerfull and it can control a person without him knowing he is being controlled. he was a gifted uchiha.danzo has his right eye and naruto his left. itachi puts acrow inside naruto,that crow has the sharingan of shisui. that crow will come out if someone activate amaterasu or tskuyomi which itachi feels will save naruto from sasuke's sharingan 's power. That power is called koto amatsukami.
itachi is better than naruto without sage mode but with sage mode naruto is stronger and faster
no it is not it came from itachi but people say it came from naruto but is really came from itachi. (:
itachi is in the lake where kakashi beated naruto in the first place
