Uchiha Madara is the legendary co-founder of Konoha Village who later defected. He is mentioned as attacking Konoha with the Nine-Tailed Fox after leaving the village. He had a bond with Hashirama Senju but did not trust Konoha without him. He is considered alive even after Hashirama's death, a source of worry for Tobirama. He advocated for the military unification of the Ninja World through force. His departure was a major event in Konoha's history, and his potential return looms over the village's security.
