Obito Uchiha

Obito Uchiha is a complex and fascinating character in the Naruto series. He is first introduced as a young ninja who sacrifices himself to save his friends, but is later revealed to be the real leader of the Akatsuki. Obito uses the alias of his benefactor, Madara Uchiha, and conceals his true identity with masks as one of the main antagonists of the series' second half. Obito's character has been praised for his portrayal as a child soldier in Kakashi's backstory as well as his fight scenes as an adult. However, his role as an antagonist has garnered a polarizing response from fans, particularly due to his perceived lack of motivation for his actions.
