4. Sasuke Uchiha
Sasuke Uchiha is one of the two legendary war heroes of the Fourth Great War, along with Naruto Uzumaki, the seventh Hokage of Konohagakure. He plays just as much a role in protecting Konoha as Naruto. Sasuke is known as the Other Hokage, or the supporting Hokage.
He has received special powers from the sage of Six Paths, which include the Six Paths Yin Chakra, and the Rinnegan in his left eye. Further, he also has his Eternal Mangekyou Sharingan in his right one from which he can produce Amaterasu, black inextinguishable flames. Apart from this, he’s very strong in Taijutsu. Overall, he is one of the strongest shinobi of all time, and is quite a candidate for 8th Hokage.
