Hashirama was originally the leader of the Senju Clan of the Forest. At some point in his life he fought Kakuzu but the nature of this fight is unknown at this point. In his early years, after they and their clans had been fighting constantly, he had his clan allied with Uchiha Madara, and the two of them, with their clans, founded Konoha. Later on, Madara left the villige over the policies of the village and his clan. This conflict resulted in battle with Uchiha Madara and the nine-tailed fox at the Valley of the End.

To commemorate the battle, two statues, of Madara and Hashirama, were carved into the earth around the waterfall. It is for this reason that Naruto Uzumaki and Sasuke Uchiha's fight at that location was noted to be ironic.

However the war still waged on, and unsure of the title of Hokage he would not only appoint his brother as his successor as the Second Hokage (Nidaime Hokage), but in a common decision with his brother they also decided that one of their students Sarutobi should become the Third Hokage (Sandaime Hokage), which in turn seemed like a wise decision as both brothers would eventually die during the wars.

He was most famous for his unique Wood Release techniques, a kekkei genkai that is a mixture of earth and water-natured chakra that creates this new element. By converting chakra into the source of life, he was able to create trees, causing them to grow to great sizes and manipulate them to diverse shapes and battle uses at will. In an instant, he could shape the entire battlefield for his own uses.
