He came to Amaru's village 15 years ago and after saving her life from a terrible illness, he was welcomed as a member of the village. During which, he revealed to be a former ninja who turned away from the path of battle to help save lives instead. When first introduced he and Amaru came to Konoha to get help for there village when the Sky Ninja appeared. During which, he demonstrated tremendous medical prowess be saving the lives several near-death victims from the Sky Ninja's attack. He and Amaru where then escorted back to their village by Naruto, Sakura, and Hinata. To their horror, when they arrived they found the village in ruins.

He also revealed to have been the one who sealed the horrible Reibi within her to gather as much Dark Chakra from the villagers as possible. He then used the dark chakra to transform into what he called the "Ultimate Body", gaining tremendous physical prowess and the ability to freely manipulate his chakra. Initially, Shinnou repeatedly and effortless demolished Naruto no despite all his attempts, but after Naruto realized Shinnou's power came from Amaru's negative emotions from feeling betrayed, Naruto helped her to let got of her those feelings, stripping Shinnou of his power source and enabling Naruto to defeat him. Unfortunately, before the final blow could be made, Sasuke appeared and intervened as he was ordered by Orochimaru to retrieve the man. Already seeing through Shinnou's power, Sasuke used his Chidori Senbon to disrupt Shinnou's chakra flow, tricking Shinnou to strip himself of all his power and reducing him to a withered old man. Growing desperate, Shinnou retreated to a chamber with the main source of dark chakra. There, he merged with the Reibi's seedling and attempted finish off Naruto and Sasuke once and for one. But once the two unleashed the Nine-Tail's and the Cursed Seal's chakra, they were able to overfeed the cocoon and destroy it along with Shinnou.
A missing-nin and S-ranked criminal, "The Masked Man" is considered a highly dangerous ninja, able to effortlessly defeat other jinchūriki like Yugito Nii as well as several of Konohagakure's top-level ninja. Menma (メンマ, Menma), a character that appears in Naruto 6: Road to Ninja, is the son of Kushina Uzumaki and Minato Namikaze in the alternate universe of Konohagakure, thus making him the "Naruto Uzumaki" of that world. Like his counterpart, he is the jinchūriki of Kurama, the Nine-Tails. (Source: Narutopedia)
The Fire Daimy� has a fickle and indecisive nature and is easily swayed in his decisions through biases as well as external influences. When situations call for fast, important decisions, he makes his advisers do the whole work: the one who convinces him most is the "winner". He seemingly had a liking for Jiraiya, wanting to choose him as the next Hokage, and was also impressed by Kakashi Hatake's reputation. (Source: Naruto.wikia)
The Great Toad Sage is the oldest and most respected toad of all the inhabitants of Mount My�boku. Because of his age, the other toads affectionately call him Great Honorable Geezer. He is famed for his highly accurate prophecies. Being several thousand years old, he is the oldest and most respected among the population of Mount My�boku. At his great age, the Great Toad Sage seems to constantly smile and tends to have his eyes closed or squinting. He is portrayed and described as being senile, and sometimes out of touch with his present situation, so he does tend to forget things easily and quite quickly. However, when reminded, he is still able to remember things and can easily tell things very precisely. As a sage, he is also very wise, and is quick to stop Shima and Fukasaku from bickering and encourages harmony. It would seem that unlike most other toads, he actually has respect for Jiraiya, and has urged both Shima and Fukasaku to cooperate with him
Obito Uchiha was teammates with Kakashi Hatake and Rin under the Fourth Hokage. Obito was frequently late for missions due to the random good deeds he would carry out, which greatly irritated Kakashi. He also seemed to have had a crush on Rin. When Rin is kidnapped during the Kakashi Gaiden arc, Kakashi, the current team leader, insisted that they continue the mission instead of saving her. Citing that those who do not save their teammates are no better than trash, Obito refused and eventually managed to persuade Kakashi to join him. During their rescue effort Kakashi lost his left eye as a result of an enemy ninja's attack, and Obito awakened his Sharingan to save Kakashi and defeat the ninja. Once finding Rin, Obito again saved Kakashi by pushing him out of the way of a rock slide, though has his right side crushed in the process. Unable to escape with his teammates, Obito had Rin implant his remaining Sharingan eye in Kakashi's damaged eye socket as a gift. In chapter 599 it is revealed that Tobi is actually Obito Uchiha who was teammates with Kakashi Hatake and Rin under the Fourth Hokage.
Rank: Chuunin Birthday: November 15 Blood Type: A Rin, a medical ninja, was the teammate of Hatake Kakashi and Uchiha Obito during the Kakashi Gaiden arc. She is a sweet and friendly girl who cares for her teammates. She is also the one who implanted Obito's left eye into Kakashi, giving him his Sharingan. She has intimate feelings for Kakashi. According to the manga she is dead, as revealed when Kakashi is killed by Pain. He apologizes to Obito because he broke their promise and failed to protect Rin. It is later revealed that Rin isn't killed by Kakashi. But deliberately went to Kakashi's raikiri.
Tobi was formerly Zetsu's subordinate, and became a full Akatsuki member after Sasori's death. He now wears the same ring as Sasori, having recovered it after Sasori's death, and took his place as Deidara's partner. Unlike the majority of ninja thus far, Tobi has not been shown wearing a visible forehead protector, so his place of origin is unknown. He wears an orange mask with single eye-hole covered in a swirl pattern concentrated towards the right eye. This odd mask that covers his entire face save for his right eye. Furthermore, Tobi has several bolts or pins present on the arms of his uniform, now obscured by his Akatsuki cloak. Tobi's area of expertise remains unclear, as he has never been shown fighting. He and Deidara have defeated the three-tailed beast, but Tobi is never shown doing anything but running from it. After the battle, which goes largely unwitnessed, Tobi claims to have knocked it out with a single attack. Deidara disagrees with the assessment, claiming that it was his "artistic contribution" (exploding clay) that allowed them to win. During his fight with Sasuke, Tobi shows the ability to recover from what are presumably debilitating or fatal blows. After being slashed across the midsection by Sasuke's sword, Tobi collapses, only to stand up again a few seconds later and complain about the speed of the attack. Aside from this, Tobi has yet to demonstrate any techniques. Tobi has a very formal and correct manner of speech. While his physical appearance remains a mystery, Zetsu has implied that he is relatively young when one side of him referred to Tobi as a "good boy." He respects Deidara, referring to him as Deidara-senpai. Tobi's personality is rather odd in comparison with other Akatsuki members. While most of the members are dedicated and serious, though somewhat argumentative or even hostile towards each other when not fighting, Tobi is more carefree and goofy, much like Naruto. His personality does not please Deidara, who believes that all Akatsuki members should be serious and calm. Tobi unintentionally irritates Deidara frequently, which usually results in Deidara attacking Tobi in a comedic fashion. However, after Deidara and Itachi's death he is later seen and heard with a more serious and calm tone in his voice. The carefree side of Tobi is not seen again. Later Tobi claims to be Uchiha Madara, the founder of the Uchiha clan and first mangekyo sharingan user. He later changes his mask after obtaining the rinnegan to allow him to use both eyes simultaneously. In fourth ninja war, when he meets Naruto and Bee he says to be no one and that they could calling him Tobi, Madara or No One. In chapter 599 it is revealed that Tobi is actually Obito Uchiha who was teammates with Kakashi Hatake and Rin under the Fourth Hokage. Obito got his right side crushed when he saved Kakashi by pushing him out of the way of a rock slide. Unable to escape with his teammates, Obito had Rin implant his remaining Sharingan eye in Kakashi's damaged eye socket as a gift. After that it was believed that Obito died.
