Sasuke Uchiha was everyone’s favorite bad boy in the original Naruto Shippuden run. At first glance a cold-hearted killer and bitter rival of hero Naruto Uzumaki, viewers were slowly introduced to Sasuke’s violent backstory.
Most of the early episodes involving Sasuke saw him locked in a deadly quest for vengeance against his older brother after the latter had murdered most of his clan. After teaming up with Naruto, Sasuke came to consider him his only friend – endearing the antihero to viewers.
But Sasuke’s ambitions to be the strongest shinobi ran deep, leading to his betrayal of Naruto. In episode 476, the pair fought a titanic battle. They charged at each other with such force that both lost an arm in the crush – Sasuke his left and Naruto his right. “The Final Battle,” as it is known, knocked some sense into Sasuke as he quickly abandoned his lust for power. While Naruto accepted a prosthetic arm after it was over, Sasuke chose not to do this, believing that the loss of his arm was just punishment for his many misdeeds.
In Boruto: Naruto Next Generations, there are no signs that Sasuke will change his mind. Even so, he is still a skilled warrior, using his katana to deadly effect. Even without his arm, Sasuke is still considered one of the strongest shinobi of all-time alongside Naruto himself. It is thought that, together, the pair have the power to destroy the world.
But the shinobi-infested world of Naruto is a dangerous one, and it remains to be seen if the reformed Sasuke will survive.
