For some awkward reason, it seems I have the only logical and sane interpretation of Chapter 224, page 10, panel 4, second sentence. (-Link) What confuses me so much is why basically everyone assumed once reading that, that he in fact -activated- the Sharingan at age 8, instead of mastering it. Now well, you might read this and think, "So, what does it matter? We can still safely assume he got the Sharingan at age 8, he did nothing important prior to that and now he has the Mangekyou so... no reason to debate this". However, what passively accepting this false belief creates is the logical deduction that at age 7, he graduated from the Academy of purely his own skill, giving him false credit... That is not the case, as I will prove through simple reasoning and logic. I feel the need to do this because I met with such... opposition when I stated that Itachi is awesome because of his Sharingan, and -only- awesome because of it that it suprised me to know that the forum base can be so misleaded. I won't debate the fact of whether it means activate or master because... well, it says it in the manga so you have really have two choices 1)Stick to your misconception about a false interpretation 2)Re-read that and see for yourself what the manga says So, for those of you who chose 1), you can leave now, for those who chose 2), let me further enlighten you... Him mastering the sharingan instead of merely activating it at such an early age holds much importance regarding just how Itachi got so strong. Obviously, since he had the Sharingan at such an early age, he had an advantage at movement predicting which made him develop confidence. That same confidence which allowed him to face enemies and copy their techniques, thus becoming strong himself. All he had to do was see the teacher do the Bunshin no Jutsu and that was it, he learned it and he could take the graduation test. Same for the bells, he would watch both of his teammates try to get the bells and the technique that they used that made them almost successful, then he would take each of their techniques and use them both and it would act as "teamwork" but from a single person. In the Chuunin Exam, he was easily exposed to a massive number of tai- gen- & nin- jutsu skills that would prove useful in later times. Along the line, he copied so many techniques and became so powerful that he despised his clan for caring about useless things. This is when he wanted to test himself to see if he was really this powerful. Which indeed he was, for proof... I refer you to him beating the FUCK out of not 1, not 2, but 3 Uchihas, all with their 3-tomoe Sharingans activated and ready. (-Link, and -Link). So, from this, we can safely say that he was moving more then triple the speed of Kyuubi Naruto @VotE. Must've copied Shishui's mirage techinque.
