P A S T

Even though Itachi has a cold and cruel personality in the present, in the past he was not always that way. He was admired and praised by all the fellow villagers and was even looked on as the true successor of the Sharingan eye of the Uchiha clan. His little brother is, of course, Uchiha Sasuke, who followed him around every chance he got. However, even Itachi's parents wondered what Itachi was hiding within himself because he was always to himself and wasn't the type to attract friends.

One night, Sasuke comes back home to the Uchiha part of the village and sees everyone slaughtered on the street. He runs home and sees a figure over the bodies of his dead parents and realizes that it's Itachi. Confused and terrified, Sasuke asks Itachi why he murdered everyone and Itachi simply replies he just wanted to test his strength. When Itachi turns around to face Sasuke, you no longer see his cool demeanor but a murderer with angry Sharingan eyes. Itachi then attacks Sasuke mentally with his eyes, making him relive the moment of his parents' death for what seems like three days in a period of a few seconds.

Itachi then leaves a mentally broken Sasuke with an order to live his life full of anger and hatred and to avenge the Uchiha clan by becoming strong and killing him. His intentions of not killing Sasuke and leaving him with such a statement are still unknown, but it is hinted that Itachi had a bitter grudge against the Uchiha clan (and not necessarily the Konoha village).

Since then, Itachi has been on the run in the shadows, a wanted fugitive by the Konoha village. One of the most powerful members of the Akatsuki terrorist group, Itachi arrives in Konoha village once again, not to face Sasuke, but to release the nine-tails demon inside Naruto.
