Minato Namikaze was the Yondaime Hokage of Konohagakure and the man responsible for sealing the nine-tailed demon fox inside Naruto Uzumaki when he was born. Doing so cost him his life, and before dying he asked that the villagers not see Naruto as the monster within him, instead wanting him to be viewed as a hero, a request ignored by the villagers. "Namikaze" translates literally as "Wave wind." "Minato" translates as "Harbor" or "Port." Minato shares a number of traits with Naruto, namely in appearance and attitude. Such comparisons are common throughout the first part of the series, and in the second as well. The second part of the series reveals that Naruto is his son, hence the comparisons, born to Kushina Uzumaki. In his youth Minato, along with two other unknown Genin, was a student of Jiraiya. Prior to becoming Hokage, he was also the sensei of Kakashi Hatake, Obito Uchiha, and Rin Nohara. Minato is said to be one of the greatest ninja Konoha has ever produced, with natural talent that had not been seen in many years. He specializes in using the Hiraishin no Jutsu, a technique the Second Hokage, Tobirama created, which essentially allowed him to teleport to any location with the use of a special seal. By attaching the seal to a kunai or an enemy, Minato could teleport to the location of the seal unnoticed, allowing him to wipe out nearby opponents almost instantly. This ability led to his title as "Konoha's Yellow Flash," and it caused him to be seen as so dangerous that a flee-on-sight order was given in regards to him during the Third Ninja War. He also created the Rasengan, a technique that does not rely on hand seals but instead uses a concentration of spinning chakra in one's palm that causes immense damage to its victim on contact. Later in the series it is revealed that technique is actually incomplete. Minato had planned to add his own nature manipulation training to the Rasengan, making it even more powerful, but could not manage to prior to his death. Later during the war he is resurrected by Orochimaru with Edo Tensei alongside all the deceased Hokage on Sasuke's demand. After Sasuke chooses to protect the village, he goes and joins the battlefield along with his fellow Hokage to help the Allied Shinboi Forces in their fight with the Juubi.
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.
Woodruff first appeared telling Ash that he was free to catch the Heracross, but if he did he might be causing more harm to the forest than he knew, since the Heracross made tree sap available to the Butterfree. Woodruff introduced himself, stating that he was a ranger for the forest and wildlife bureau.
He is a fairy. He is a servant of Runa, just like Suneri
