He awakened the Sharingan when he was 8 years old. It is hard to conceive how much grief has been reflected in those eyes...
In addition to the obvious doujutsu and genjutsu powered by the Sharingan, he is also very skilled in taijutsu and ninjutsu.
 Itachi became an anbu squad leader at 13. He killed his own clan soon after that.
Actually Itachi had a girlfriend. But he killed her at the night he cleared the whole clan.
[Mangekyou Sharingan]
Itachi sacrificed himself, and by having his brother witness his death with his own eyes he left him the "Mangekyou Sharingan". "I will always exist with you"—Itachi arranged everything so that even after dying he could still protect Sasuke.
