6 – Madara Uchiha
Co-founder of the Hidden Leaf Village and rival to Hashirama Senju, Madara Uchiha is acknowledged in-universe as one of the most powerful Naruto characters in the series. Hailing from an age before ninja villages were established, his legendary strength required the combined forces of the current leaders of the Hidden Villages simply to match him for a time. It is for this reason that he holds Rank 6 in this list.
5 – Hashirama Senju (First Hokage)
Hashirama Senju, the co-founder of the Hidden Leaf Village and First Hokage, holds the Rank 5 spot in this list. In his youth, he faced off against his former best friend Madara Uchiha a number of times before the two joined forces to help form the Hidden Leaf Village. However, things between them grew tense and the two inevitably clashed once more, with the battle carving out the waterfall that would become known as the Valley of the End. Hashirama possess great strength and skill with his ability to manipulate wood, enough to make even the arrogant Madara consider him his true equal.
4 – Kaguya Ootsutsuki
The mother of Hagoromo (who would later become the Sage of Six Paths) and Hamura, she became the first being to use chakra and attained god-like power to bring about peace. Sadly, she is corrupted by all that power and turns into the Ten-Tails until her children defeat and seal her away. When she returns at the climax of the Fourth Shinobi World War, her numerous abilities help demonstrate just how powerful she is.
3 – Sasuke Uchiha
Taking Rank 3 in the list by storm is Sasuke Uchiha, a member of Team 7 along with Naruto, Sakura, and Kakashi. Having been orphaned at a young age by his brother’s ‘betrayal’, he dedicated himself to becoming strong enough to kill him. While he makes many questionable decisions over the course of the series, he undeniably becomes one of the most powerful characters in the franchise with his skills, along with both the Sharingan and Rinnegan eyes.
