They are know throughout the world for their powerAt least, the Uchiha-clan would be the most powerful if it still existed. A terrible tragedy has overcome this clan. Uchiha Itachi, Sasuke's older brother, single handedly wiped out the entire clan. He left only one survivor: Sasuke.
After the massacre Itachi left the Leaf and continued his quest for power. Sasuke on the other hand, was left behind alone and confused. Now he lives only to take revenge on his brother and try to revive the Uchiha-clan once more.In Itachi more then Sasuke, you can clearly see the pure power and genius that flows thought the blood of all members of the Uchiha-clan. Not to mention the fact the that they have Sharingan (the most wanted advanced bloodline ability of all!), they truly are natural born ninjas/killers. At the very young age of 10, Itachi became a chuunin. And now he might even be the most powerful ninja alive. Although Sasuke isn't quite as impressive as his older brother, he still is one of the most talented rookies around.
