CS2 Sasuke owned Kyubbi at the Valley of the End.
Naruto ehm no, sasuke
Sasuke's mangekyo sharingan.
yes and no. Naruto AND Sasuke will become the strongest ninjas, their strengths will be approximately equal. Naruto will become stronger than his father. IDASHI UCHIHA IS THE STRONGEST NINJA of course he will!
The Sage Of Six Paths was the strongest ninja ever to set foot on Earth and invented Ninjutsu. Hiruzen Sarutobi is also very strong as he was the Third Hokage and the strongest of the Hokages. Pain is also very powerful (with his rinnegan) and Tobis serious form is also very powerful so we cannot determine the strongest ninja.
I will assume you are speaking of Naruto. None are really the strongest. They are all weak against some natures, and strong against others.
Im going to note, chidori is a fictional jutsu made up in the Japanese anime Naruto. Kakashi first invented it, but it is later taught to Sasuke Uchiha.
sasuke because he is in orochimaru's hands and sasuke now has mangekou sharingan
No he is not. The strongest ninja is the sage of six paths. He is the one who invented the ninja world and jutsu and beat the ten tailed jinjuriki.
No Naruto isbut sasuke has the cooler skills :Dlol you suck here is the info: [[Q/Who is the strongest naruto character&updated=1&waNoAnsSet=2|http://wiki.answers.com/Q/Who is the strongest naruto character&updated=1&waNoAnsSet=2]]No the strongest character is the 1st Hokage seeing as how he defeated the strongest Uchiha in history the 1st user of the EMS as well as the Nine Tailed Fox at the same time.
Well this all depends. Before Naruto Shippuden was released, Sasuke was stronger than Naruto. But around the middle of the Shippuden series, Naruto started to grow up, and received exclusive training. (as did sasuke, he just didn't have the results that Naruto did) Which increased his skill greatly, surpassing Sasuke for the moment. Now when Naruto is in Sage mode, he is no doubt the strongest in the villiage (in my opinion) (besides danzo, because we don't know how strong he is yet.) But this topic is very debaitable and will be debated until proven in the series. My opinion:::: Naruto
no... naruto is the strongest charcter (ninja) in the ninja world
Sasuke

In my opinion, Naruto is. I hate Sasuke.
