First Hokage

The First Hokage (初代火影, Shodai Hokage?, literally "Founding" or "First Hokage") was the founder of Konoha and used his unique Mokuton abilities to create the village. He was the older brother of the Second, and the grandfather of Tsunade. During his life he fought Kakuzu, but the details of their battle are never elaborated upon. He saw the people of Konoha as a part of him, and put them before anything else. His spirit even now takes a firm root in Konoha. He was resurrected and summoned by Orochimaru to battle the Third Hokage, who is eventually forced to seal away his soul to defeat him. Prior to this defeat, the First uses Bringer of Darkness Technique (黒暗行の術, Kokuangyō no Jutsu?, English TV "Infinite Darkness Jutsu") to cause the Third to see nothing but total darkness, allowing the First to attack him unseen. In earlier years Orochimaru injected the First's DNA into 60 test subjects in an attempt to replicate his Mokuton abilities. Only one of the test subjects, Yamato, survived and retained the First's abilities.
