This Ten-Tails (十尾, Jūbi) is the combined form of Kaguya Ōtsutsuki and the God Tree, created to reclaim the chakra inherited by her sons, Hagoromo and Hamura. It is regarded as the progenitor of chakra, and is tied to the legend of the Sage of Six Paths and the birth of shinobi.
But since the power of the tailed beasts is measured by the number of their tails I could say that the eight tails is stronger than the nine tails if orochimaru did not release the technique but since he did then the nine tails is much stronger.
The 12 Tails are the main playable character classes of the 12 Tails Online game. The Tails, ordered in alphabetical order, are Bat, Bison, Cat, Chameleon, Mole, Monkey, Panda, Penguin, Rabbit, Sheep, Whale, and Wolf.
The Zero-Tails bears some resemblance to the spirit No-Face, a character in Hayao Miyazaki's Spirited Away. Despite the beast referring to itself as Zero-Tails and Shinnō referring to it as a tailed beast, it is not really one of the original tailed beasts due to the fact that it was not born from the Ten-Tails.
Will Kurama Come Back to Life? Sadly, there's no hint of Kurama coming back to life in the Boruto manga series when writing this post. So, it's safe to say that's how things will stay in the anime as well. In the manga, Kurama died in chapter 55, and episode 219 adapted 11 pages from the same chapter.
Hagoromo Otsutsuki created the Tailed Beasts by tearing off the chakra of the Ten-Tails from its husk and the. splitting it. Essentially, the Tailed Beasts are simply masses of chakra given form using Creation of All Things. However, the Creation of All Things could easily have given them a body as well.
Naruto, Sasuke, Sakura and Kakashi manage to seal Kaguya, who reverts into ten tails before being sealed spitting out Madara. Eventually, Madara dies because of the toll of both the tailed beasts and Demonic Statue removed from his body.
Not only did he have a powerful Mangekyo Sharingan with the ability of Kamui but he also had the Rinnegan as well. If that wasn't enough, he went on to become the Ten-Tails Jinchūriki, which easily confirms that his level of strength surpassed that of all the nine Tailed Beasts.
There were a total of nine tailed beasts in the Narutoverse, related essentially as siblings. However, the one-tail developed a rivalry with the nine-tails, causing them to always quarrel and try to surpass each other in everything.
Hashirama Senju was able to take on Madara and 'Kyuubi' cloaked in a Susanoo. His wood release is extremely powerful and he also has the ability to enter Sage Mode. Since Hashirama was able to beat Madara and Kurama cloaked in a Susanoo, he would be able to take on the nine tailed beast by himself.
