Naruto has had the seal of the nine-tailed fox on his body since he was a child. Of course, this seal will accompany him throughout his life. Whenever the nine-tails explode, it is the most uncomfortable time for Naruto. It is also the time when the celebrity is very powerful. But Kyuubi must be suppressed. If he cannot be suppressed, Naruto may die suddenly and Kyuubi will cease to exist. Of course, there are a few powerful people who can restrain Kyuubi. Six Paths Sage, Senju Hashirama, Uchiha Madara, Uchiha Obito, and Sasuke, these five people can be completely suppressed.
Sasuke, Naruto's former good friend and training partner since childhood, turned black because of Orochimaru. Sasuke has a kind of eye power, which can penetrate deep into Naruto's body. Seeing the Kyuubi and communicating with it to achieve suppression. Of course, this power can only suppress a small number of tails. If the Kyuubi appears, it may not be able to suppress it.
Six Paths Sage, the creator of Kyuubi, is fully capable of suppressing Kyuubi. After all, he is Kyuubi's biological father. Although he appears very rarely in the anime, he is still a very powerful one. Character, many ninjas are a little afraid of him. Senju Hashirama, he has the ability to control tailed beasts. Nine-tails is also a kind of tailed beast as the name suggests, so Nine-tails can be completely controlled by him. Uchiha Madara possesses the ultimate Mangekyō Sharingan. This Sharingan is arguably the most powerful Sharingan among Hokage, and it is easy to suppress the Nine-Tails. Uchiha Obito's genjutsu is also a very powerful ninjutsu. He can completely conjure up a genjutsu to talk to Kyuubi and suppress Kyuubi.
Although these five people can restrain the Kyuubi, these five people are not good people. Suddenly, I feel that Naruto is really pitiful.
