Matatabi

Matatabi, more commonly known as the Two-Tails, is one of the nine tailed beasts. It was last sealed within Yugito Nii of Kumogakure. Matatabi and the tailed beasts first came into being in the waning days of Hagoromo Ōtsutsuki, who used his Creation of All Things Technique to divide the Ten-Tails' chakra into nine separate bodies and giving each a name. Some time after being created, the Sage explained to the young tailed beasts that a link existed between them despite their separation. He also foretold of a day when they would be brought together again - though not as they were - and that at that time someone would emerge to show them what true power is. After Hagoromo's death, the tailed beasts drifted apart, apparently due to Kurama's belief that their number of tails was an indication of their strength. Like Shukaku, many people believed that Matatabi was once a human that turned into a living ghost.

Matatabi eventually fell into the possession of Kumogakure and was sealed within Yugito Nii when she was two years old. She was placed into a detestable training program in order to learn to control Matatabi's power. In the anime, Yugito agreed to have Nekobaa collect Matatabi's paw print for the Paw Encyclopaedia. In a cavern behind the Falls of Truth, where jinchūriki learn to control their tailed beasts' power, there are wall murals of Matatabi and Gyūki, which indicates how long they were associated with the Land of Lightning. Compared to most of the tailed beasts, Matatabi has shown to be respectful and polite towards others, speaking in a formal manner using "watashi" when referring to itself and using honourifics when addressing Naruto while introducing itself to the young shinobi. Matatabi is a bakeneko that is completely engulfed in blue flames. It also has a right yellow eye and a left green eye, similar to an odd-eyed cat without pupils. When forced to transform by Tobi, Matatabi increased in size compared to when Yugito unleashed it. During the last remaining days of the Sage of Six Paths' life, Matatabi was a young flaming kitten much smaller than its present-day self, but was still much larger than the Sage. As a tailed beast, Matatabi has an enormous supply of chakra that it can transfer to others and can create the Tailed Beast Ball. As its appearance suggest, it can use Fire Release, which it can lend to its jinchūriki. Matatabi also has flexible muscles, which grant it great speed despite its large size. Matatabi's raw strength can easily crush an opponent or send them flying with one swipe of its paw. When combined with the other tailed beasts' tails, it could shatter and completely obliterate a senjutsu-enhanced complete Susanoo. Soon after her introduction, Yugito was captured by two Akatsuki members, Hidan and Kakuzu, although it is unknown who was specifically assigned to capture her. Despite luring her two pursuers into a closed space, sealing the exits, and transforming herself into the Two-Tails, Yugito was overpowered and rendered unconscious by the two Akatsuki members. Zetsu later arrived to take her off their hands. After three days of the Akatsuki extracting the Two-Tails into the statue from Yugito and getting sealed, its jinchūriki died afterwards as a result of having her tailed beast extracted.

After Son Gokū was resealed into the Demonic Statue of the Outer Path, Tobi, who was intent on going all-out from that point on, forced Yugito to fully transform into the Two-Tails. The opposing tailed beasts prepared to attack the shinobi, but they were rebuffed by a fully-transformed Naruto. Wasting no time in their attacks, the Two-Tails attempted to pounce from behind while Naruto and Kurama were incapacitated by the Six-Tails, but both the giant cat and slug got slammed with such force that they were sent flying. The opposing beasts regrouped and then prepared a collaborative Tailed Beast Ball, which was met by one from Naruto and Kurama. As Naruto entered a deeper plane of the tailed beasts' consciousness, he met the remaining five tailed beasts and their jinchūriki. Summoning Naruto before it, the giant cat told the young shinobi that it intended to keep the promise it made to Son Gokū. As it told Naruto to stretch out his hand, Matatabi introduced itself. Later, as Matatabi was freed from the chakra receiver, it affirmed Kurama's belief that Naruto was the person the Sage of the Six Paths had spoken about so long ago before being resealed into the Demonic Statue of the Outer Path. Matatabi appeared alongside the other tailed beasts with the exception of Gyūki and Shukaku when the Ten-Tails looked down at Naruto. The image of the tailed beasts, along with a silhouette of the Sage of Six Paths, drove the Ten-Tails to a fit as it evolved further. Later, Naruto, with the help of the remaining Allied Shinobi Forces, managed to free Matatabi by pulling its chakra out of Obito's body, alongside that of the other tailed beasts. When Madara ran towards the tailed beasts, both Shukaku and Gaara conjured numerous sand bullets and were able to restrain the Uchiha's movements. Using the opportunity to attack, the tailed beasts each took a swing at their opponent, giving sand-manipulating duo an opening to use their Desert Layered Imperial Funeral Seal, but Madara managed to escape the sand pyramid with his Susanoo. As Naruto in Tailed Beast Mode pinned Madara down with a tail, Matatabi and the other tailed beasts joined in and did the same to increase the damage, but the Uchiha survived their attacks and retreated to a safe distance. After he received his own right Rinnegan eye from a White Zetsu clone, Madara quickly summoned the Demonic Statue of the Outer Path from Obito's body, and used the Rinnegan to repel the tailed beasts. With the tailed beasts stunned, Madara then chained them up and sealed them back into the Demonic Statue. Later, the chakra Matatabi transferred to Naruto earlier, manifested within Naruto's subconscious along with the other tailed beasts to speak with the young jinchūriki and the spirit of Hagoromo Ōtsutsuki. There, they all voiced their shared belief to the Sage that Naruto was the child of prophecy. After Madara's ambitions were cut short by Black Zetsu, who revealed to be the silent manipulator of shinobi history since it was first created by Kaguya Ōtsutsuki, the black entity used Madara's body as a medium to resurrect its creator. During the battle against the tyrannical princess, Matatabi and the other tailed beasts continued to support Naruto by giving him their combined power to overwhelm her. Ultimately, Kaguya was defeated by Naruto and Sasuke, who used the Six Paths Chibaku Tensei to eject all the tailed beasts from her and seal her away inside a newly-created moon within her own dimension. After the spirits of Hagoromo and the past Kage summoned both the tailed beasts and Team 7 back to the real world, the tailed beasts began to discuss their plans for the future since they were finally free. Sasuke, however, made his own intentions known: removing as many people as possible who could get in the way of his plans of leading the world through a revolution to do away with current shinobi systems, including killing all the current Kage and tailed beasts. Just as Sasuke swiftly subdued the tailed beasts with his Rinnegan and sealed them within his Chibaku Tensei, Naruto reassured the tailed beasts that he would save them once again. After Naruto was able to defeat and reform Sasuke, the two dispelled the Infinite Tsukuyomi and Sasuke released Matatabi, along with the other tailed beasts, from their prisons.
