Fourth Shinobi World War: Climax ArcEdit
When Hashirama was first revived by Orochimaru during the war, he explains that he and Madara first met when they were children, and since then they became very close friends. They used to spend time together at the edge of the river where they first came across, talking, sparring and sharing their ideas. However, their friendship was not long to last, as Butsuma soon discovered from Tobirama that his son had been meeting with Madara. Revealing to Hashirama that Madara was in fact an Uchiha who had killed several of the Senju's strongest shinobi, he ordered his son to use his meetings with Madara to spy on him and, if necessary, to kill him.Still, Hashirama could not stand to betray his friend; when the two boys met again. they warned each other that a trap had been set for the other, but as they fled, they looked back in shock to find their fathers and younger brothers standing across from each other, fully ready for combat. After Hashirama and Madara intervened to protect their respective younger brothers, Hashirama was devastated to see Madara end their friendship and declare them mortal enemies. As the years passed, Hashirama was forced to battle his once-friend many times before they eventually became the leaders of their clans. Sometime afterwards, Madara and Izuna fought Hashirama and Tobirama, where Izuna was mortally wounded by Tobirama. Madara retreated and Izuna died from his wounds but left Madara his eyes, granting him the Eternal Mangekyō Sharingan. Madara later confronted Hashirama again with his new found ocular prowess, but nonetheless, after a day-long battle, he was finally defeated. Noting that he could not trust them any more, Madara told Hashirama that the only way to regain this trust was to either kill himself or his brother. When Hashirama resolved to kill himself, Madara stopped him, noting his courage and accepted the truce.
The Senju and Uchiha clans formed many other alliances with other clans and began to create the Hidden Leaf Village. Hashirama and Madara's relationship began to become more and more like it had been when they were young. While looking at the construction of the village from the mountain point they had sparred on as children, Hashirama expresses his desire for Madara to become the village's first Hokage. Madara denies, saying that the Uchiha still lacked everyone's trust. He points out that Hashirama will most likely be the first and then his younger brother the second.
Later, Madara overhears a conversation between Tobirama and Hashirama. Angered by Tobirama's distrust towards him, Madara leaves. Eventually, Madara defects from the village and attacks it several times. Finally, a battle between him and Hashirama takes place. During the battle, Hashirama showed reluctance to kill his former friend, but eventually severely wounded him, ending the battle in what appeared to be Madara's death.
When leaving to the battlefield to once more battle against his former friend with the rest of the Hokage, Hashirama stops at the same mountain that him and Madara had sparred on several decades before. He admits that while he is disappointed, he is quite excited to see his rival once again.
When the hokages arrives on the battlefield, Madara senses that Hashirama has elsewhere been brought back to life. Excited at the prospect of fighting his rival again, Madara eagerly awaits his arrival. When he arrives, Hashirama sends only a wood clone to face him, being too busy restraining the Ten-Tails. Madara decides to sit out the fight until the real Hashirama is ready. When the wood clone persists, Madara easily defeats it.Madara tries to forcing obito to revive him but obito is able to resist his control. Madara is done waiting,Hashirama is no longer preoccupied, so Madara forces him into a fight. As their battle rages, Hashirama tries to convince Madara to postpone, but Madara repeatedly refuses. Nevertheless, he keeps track of Obito's progress and growing control of the Ten-Tails' power. After Obito's defeat, Madara is restrained by Hashirama's wood dragons and the Alliance moves in to seal him.
As Sasuke is about to go after Madara, Hashirama offers to give him a jutsu that can be used to cancel the senjutsu chakra Madara has taken, stated that he resembles Madara's brother and that maybe will remind Madara of the kind person he used to be before Izuna's death.
