Izuna Uchiha is Madara Uchiha&#039;s younger brother. He was alive about 70 years before the start of the series, even before the founding of Konoha. Standing at the top of the Uchiha clan with his brother, Izuna was one of the first to obtain the elusive &quot;Mangekyou Sharingan&quot; (along with Madara). However, Madara went blind due to the use of his. To alleviate this, Izuna gave up his eyes so that Madara would obtain a new, &#039;permanent&#039; Mangekyou.

Before Naruto's birth, a great demon fox had attacked the Hidden Leaf Village. A man known as the 4th Hokage sealed the demon inside the newly born Naruto, causing him to unknowingly grow up detested by his fellow villagers. Despite his lack of talent in many areas of ninjutsu, Naruto strives for only one goal: to gain the title of Hokage, the strongest ninja in his village. Desiring the respect he never received, Naruto works towards his dream with fellow friends Sasuke and Sakura and mentor Kakashi as they go through many trials and battles that come with being a ninja. 

Naruto: Shippuuden is the continuation of the original animated TV series Naruto. The story revolves around an older and slightly more matured Uzumaki Naruto and his quest to save his friend Uchiha Sasuke from the grips of the snake-like Shinobi, Orochimaru. After 2 and a half years Naruto finally returns to his village of Konoha, and sets about putting his ambitions to work, though it will not be easy, as he has amassed a few (more dangerous) enemies, in the likes of the shinobi organization; Akatsuki. <br><br>
