Hokage

The Hokages
Hokages (火影, Fire Shadow) Are the leaders of Konoha. They are generally the strongest in the village, although idealogy and renown plays a large part in their being chosen for the position.

Five shinobi have gained this title so far.

First Hokage
The First Hokage (Shodaime Hokage) was the founder of Konaha, the older brother of the Second, and the grandfather of Tsunade, the Fifth Hokage of Konaha. Together with his brother, the Second Hokage, he trained the future Third Hokage Sarutobi. The First was famous for his Mokuton jutsus, which allowed him to convert chakra into lifeforce and grow trees with ninjutsu. In conjunction with a special crystal that reacts only to his chakra, he could use this ability to suppress the Tailed beasts chakra. He saw the people of Konoha as a part of his own family, and his legacy takes a firm root in the village.

Later it was revealed that Orochimaru had implanted the First Hokage's DNA into sixty test subjects in an attempt to gain access to his Mokuton techniques and ability to control bijuu, producing Tenzo (later given the code name Yamato). However, he lost track of the test subjects and didn't realize that one had survived. At some point in the First's life he fought Kakuzu but the nature of this fight is unknown at this point. He also battled with and defeated Madara Uchiha at the Valley of the End, despite Madara being capable of summoning the Ninetailed Fox itself.

He is later revived from the dead by Orochimaru using Impure World Resurrection to fight the Third Hokage during the Destruction of Konaha arc. His soul is eventually sealed into the stomach of the Death God, along with his brother and Orochimaru's arms.

Second Hokage
The Second Hokage (Nidaime Hokage) is the younger brother to the first Hokage and Tsunade's great-uncle. He was also, along with his brother, the teacher of the Third Hokage. He was very proud of his superior combat ability and his excellence with water jutsus, which allowed him to, among other things, use a water wall at full strength without a water source.

He is later revived from the dead by Orochimaru using Impure World Resurrection to fight the Third Hokage during the Destruction of Konaha arc. His soul is eventually sealed into the stomach of the Death God, along with his brother and Orochimaru's arms.
