9 & 10. Sasuke Uchiha and Naruto Uzumaki

The battle between Naruto and Sasuke at the “Valley of the End” was one of the most intense duels in Shinobi history. This location stood witness to their emotionally charged and nostalgic clash, reminiscent of their previous fight as children.

In this confrontation, Naruto and Sasuke unleashed their full power, using their signature Jutsu. Both fought with everything they had, pushing themselves to the very brink of their strength. Eventually, they were forced to continue their battle with nothing but fists and kicks, as their chakra had been completely drained.

The climax of the duel came when Naruto and Sasuke launched their final attacks. Naruto used his Rasengan, while Sasuke unleashed Chidori enhanced with Kagutsuchi. The two attacks collided, creating a massive explosion that shattered the statues of Madara and Hashirama at the Valley of the End.

As a result of this final clash, both Sasuke and Naruto lost one arm each. They lay motionless, severely weakened and on the verge of death. This battle became a symbol of sacrifice and the unbreakable bond that ultimately led to their reconciliation.
