they thought there was only 10 tailed beasts but there was a 11 tails who appeared 100 years after the war that Naruto, Sasuke, Sakura, Obito, Kakashi all fought in against Kaguya Otsutsuki. the 11 tails is stronger then the 10 tails and stronger then Naruto, Kaguya, Sasuke, The Sage Of Six Paths combined (frightening right?). this is an OC story in the Naruto World ^^.
