Nibi

The Nibi, also known as the Two-Tailed Beast, is a powerful demon that was sealed within Naruto Uzumaki during his childhood. The Nibi is a very dangerous and destructive creature, but Naruto has learned to control its power and use it for good. The Nibi was originally sealed within a young woman named Kushina Uzumaki, who was the wife of Minato Namikaze, the Fourth Hokage of Konohagakure. Kushina was a powerful kunoichi, and she was able to control the Nibi's power for many years. However, when she was pregnant with Naruto, the Nibi escaped from her control and attacked Konohagakure. Minato and Kushina were able to seal the Nibi within Naruto, but they both died in the process. Naruto grew up with the Nibi sealed within him, and he was often bullied and ostracized by the other children in the village. However, he eventually learned to control the Nibi's power and use it to protect his friends and family. The Nibi is a powerful and dangerous creature, but it is also a symbol of hope and strength. Naruto has learned to control the Nibi's power, and he uses it to protect the people he loves.
