itachi hasn't shown us his true power yet!!

[Easyfathom]

I can imagine that he is gonna pull somert else out of his crows xD
But be a tad rediculous to give him even more :S

 

[Chief Toad]

Of course Itachi has some tricks up his sleeve the only reason why you think you know is because of how he did sasuke but really he was just showing him the ins and outs of the mangekyou sharingan you think Kishi would let itachi put all his tricks out on the table against sasuke when he knew he was coming back that wouldnt be very clever of kishi and he's very clever indeed

Agreed on how he did his little bro but please let him have one more badass jutsu that Sasuke will never be able to copy just to make him the official GOAT (Greatest Of All Time) Sharingan user only because no one has seen Madara use Amaterasu or Tsukutomi.

 

[soulless uchiha]

he hasnt gotten serious yes

We haven't saw itachis full power but at the end of the day he blitzed the uchiha clan with kunais and shurikens because he was extremely skilled. I haven't saw no ninja in naruto that can match or has better skill in Kunais and shurikens that uchiha itachi

 

[GofOfNothing]

we never saw him going 100%
even now kishi doesnt let us see him how strong he is when he fights 100%

itachi doesnt need any more power -.- not only do people think he is a GOD already, but he seems to know everything about everything...kabuto reveals something nobody knew existed...."just as i thought!!"....seriously what els could u possibly give him!!? rinnegan?? a tailed beast???? wtf -.-

 

[Jorge95]

Some people here are exaggerating, I think we haven't seen him in full-potential because of his disease and the fact that he had decided to be killed by Sasuke (my opinion); and the last chapter left us some info that he could have one more awesome technique.

the only thing we need to see more from him is his arsenal and thats it, he most likely has more jutsu.
