Hashirama Senju

Hashirama Senju (千手柱間, Senju Hashirama) was the First Hokage (初代火影, Shodai Hokage; Literally meaning "First or Founding Fire Shadow"). He helped create Konohagakure along with his younger brother, Tobirama, and the Uchiha clan.

Hashirama was originally the leader of the Senju clan. Under his leadership the Senju clan came to be regarded as one of the two most powerful clans in the world, rivaling the renowned battle-oriented Uchiha clan. Because of this, when someone hired the Senju clan, the opposing side would hire the Uchiha clan and vice-versa, causing frequent battles between the two. Eventually growing tired of the constant fighting, Hashirama and his clan approached the Uchiha and offered a truce with them. Allied with Madara and his clan, the two groups founded Konohagakure.
When deciding who should become the leader of Konoha, the villagers selected Hashirama over Madara for the title of First Hokage. Fearing that Hashirama would oppress the Uchiha, Madara left the village, and challenged Hashirama's rule. After an intense battle that included the Nine-Tailed Demon Fox, Hashirama defeated Madara; and Hashirama's wife Mito became the Nine-Tails' first jinchūriki by sealing it within herself.^[2] In the aftermath of their battle, Madara was believed to have been killed, and the Valley of the End was created. Madara would later state that he fought that battle in order to obtain Hashirama's abilities. To commemorate the battle, two statues, of Madara and Hashirama, were carved into the earth surrounding the valley.

During his time as Hokage, Hashirama came into possession of a scroll filled with kinjutsu, which he sealed away in order to keep the jutsu within a secret. He also defeated Kakuzu, who had been sent to assassinate him by Takigakure. At some point, Hashirama gained control of several tailed beasts. He spread these beasts to other, newly-formed villages in an attempt to maintain peace and equalize the powers between the nations, but it did not stop the outbreak of the First Great Shinobi World War. Thinking about the future of Konoha, he and his younger brother, Tobirama Senju, trained the young Hiruzen Sarutobi. Hashirama would eventually die during the war, but not before passing on the title of Hokage to Tobirama.
