I think everyone who watched Naruto (even the first part) has at least heard of Hashirama Senju. In case you didn’t hear/remember him, there’s a short description.
Hashirama Senju was the First Hokage of Konohagakure. He was famous in life as the God of Shinobi for his unmatched ninja prowess. Despite that, Hashirama only wanted peace, and to that end founded Konoha with his childhood friend and rival, Madara Uchiha. Although he was not able to achieve peace during his lifetime, his legacy would live on to continue to shape the village for decades after his death.
