Who is the most powerful ninja in naruto?

Answer 1

Either Orochimaru or Hiruzen Sarutobi. While Orochimaru's life mission was to learn every jutsu, he actually did not live a longer life than Hiruzen Sarutobi, who was known as the Professor for his vast knowledge of jutsu. Orochimaru may have surpassed Hiruzen due to Orochimaru's willingness to delve into forbidden techniques and the fact the Hiruzen spent much of his later life serving as hokage rather than actively creating new techniques in combat.

Answer 2

Naruto, he has more chakra capacity than Kakashi, more powerful taijustu than Guy when he's in Nine Tails mode, and he destroyed ALL Six Paths of Pain
