The Ten-Tails is a fictional character from the popular Japanese anime and manga series called “Naruto.” It is a powerful and malevolent creature known as a Tailed Beast or a Bijuu, and it plays a significant role in the story’s overarching plotline. The identity of the entity responsible for killing the Ten-Tails is a complex and multifaceted topic, involving multiple story arcs, characters, and events. To provide a comprehensive answer, let’s delve into the rich lore and history of the Naruto universe.

The Ten-Tails is the most powerful of the nine Tailed Beasts, also known as Bijuu, which are creatures with immense chakra (a form of energy) sealed inside them. The Ten-Tails possesses immense power and is capable of causing mass destruction, making it a fearsome and formidable entity. The story of the Ten-Tails’ demise is a pivotal plot point that occurs during the Fourth Great Ninja War, an epic conflict that spans across the Naruto series.
The Fourth Great Ninja War involves multiple factions, including the Allied Shinobi Forces, led by the Five Great Nations of the Naruto world – the Hidden Leaf Village (Konohagakure), the Hidden Mist Village (Kirigakure), the Hidden Cloud Village (Kumogakure), the Hidden Rock Village (Iwagakure), and the Hidden Sand Village (Sunagakure). These factions unite to combat the forces of the villainous organization known as Akatsuki, which seeks to capture and control the Tailed Beasts, including the Ten-Tails.
Throughout the Fourth Great Ninja War, various characters from the Naruto universe engage in battles against the Ten-Tails. One of the key characters involved in the Ten-Tails’ defeat is Naruto Uzumaki, the series’ protagonist and a powerful ninja from the Hidden Leaf Village. Naruto, along with his friends and allies, including Sasuke Uchiha, Sakura Haruno, and Kakashi Hatake, play critical roles in the Ten-Tails’ downfall.
As the story progresses, Naruto and his comrades face numerous challenges and confrontations with the Ten-Tails, as it evolves and becomes more powerful. The Ten-Tails is controlled by various antagonists throughout the series, including Obito Uchiha and Madara Uchiha, who manipulate its power for their nefarious purposes.
Obito Uchiha, also known as Tobi, is a former comrade of Kakashi Hatake and a member of Akatsuki. He is initially revealed to be the one responsible for orchestrating the Fourth Great Ninja War and controlling the Ten-Tails. Obito seeks to create a world of his own design, using the Ten-Tails’ power as a tool for his plans. However, his motivations are eventually revealed to be more complex, and he undergoes a change of heart.
Madara Uchiha is a legendary ninja from the Uchiha clan and one of the main antagonists of the Naruto series. He is initially believed to be dead, but it is later revealed that he orchestrated events behind the scenes, including manipulating Obito and controlling the Ten-Tails. Madara seeks to use the Ten-Tails’ power to achieve his vision of an ideal world.
However, as the story progresses, Naruto and his allies confront both Obito and Madara, engaging in epic battles against them and the Ten-Tails. They work together, using their unique abilities and strategies to combat the overwhelming power of the Ten-Tails and its controllers. The conflict involves various plot twists, character development, and emotional moments, as the fate of the Naruto world hangs in the balance.
