"Naruto" became famous for its exceptional villains, challenging the heroes not only in battle but also in their ideals. However, not all villains were well-received. One criticism of "Naruto Shippuden" was the introduction of Kaguya and the unexpected demise of Madara. Despite this, Kaguya's appearance had been foreshadowed, and her role helped expand the series by introducing dimensions and the powerful Otsutsuki clan. The fight against Kaguya allowed characters like Sakura, Kakashi, and Obito to shine, proving their importance in the series. Naruto and Sasuke had to surpass their limits to defeat Kaguya, leading to a memorable final battle. While Madara was a beloved character, Kaguya's role was essential for the story's progression and the creation of the sequel series, "Boruto." The decision to feature Kaguya instead of Madara ultimately benefited the franchise's longevity.
