Tobi

Tobi is a major antagonist alongside Sasuke Uchiha and a warrior of the Uchiha Clan.

The former Team Jin member, Tobi rises to become a powerful Akatsuki leading figure and later a pseudo-jinchūriki. Due to Goddess Vishnu's purification, Tobi was freed from the Will of Hatred and later became an anti-villain for the rest of the series. He later became Hokage after Kakashi Hatake was sixth Hokage. (This is all cap)

Beginnings
Born without knowing his family, Obito strived for greatness, but was held back by his lack of abilities. Throughout his trainings, he was met by Jin Kariya who recruited him and Rin Nohara. Throughout the Second Warriors War, Obito was killed in an ambush and was saved by Madara Uchiha. Due to his training with Madara, he called himself Tobi and became the leading figure of Pein's faction known as Akatsuki.

Before Minato Namikaze's death, Tobi went to a village where he murdered friends and families of Kenshin Himura.

Akatsuki-Espada War
Tobi first entered the Second Warriors War since the invasion of Organisation XIII led by Xemnas who mistakenly assumed Akatsuki was once a member of the parent faction. Tobi waged war with Organisation XIII. With victory at hand, he went to search for the tailed beasts while Pein led Akatsuki to battle another rival faction known as Espada.

Fourth Warriors War
Remembering Pein's death and Konan's desertion of Akatsuki, Tobi and Aizen moved to kill Konan and gotten hold of Pein's rinnegan. Kabuto summoned a number of undead warriors with the use of Summoning: Impure World Reincarnation, Zetsu clones were amassed by the Demonic Statue of the Outer Path.

With everything prepared, Tobi, Aizen, Kabuto, Yue, Sasuke Uchiha, Zetsu and the horde of undead warriors were mobilised.

On the Crashing Wave Coast, Tobi unleashed Demonic Statue of the Outer Path to decimate a huge portion of the warriors. Jūgo, Suigetsu and Sasuke attacked the other parts where Luffy, Ivankov and Jinbei repelled them. InuYasha and Sesshōmaru repelled the life-sapping bolts with Sōryūha, forcing Tobi to retreat to Hueco Mundo.

Hunt for Nine Tails
As dawn breaks on the second day of the war, Tobi prepared the undead jinchūrikis for the right time.

Iritated by the fact Naruto Uzumaki was killed by InuYasha, Tobi was in search for Nine Tails. He saw Usagi Tsukino, Rei Hino and Ami Mizuno fighting against a demon to save Tomoe Mami. Tobi later captured Rei and escaped. To block his escape, Suigintou in Alice Form faced Tobi who eluded her.

He met Sailor Galaxia, at some point, who promised him the location of Nine Tails which was Tamamo-no-Mae. As Tobi entered Noihara, he spotted Himari Noihara and subdued her and captured the Nine Tails. Once the capture was done, he warned Galaxia not to underestimate Suigintou. Tobi gathered Kabuto, Sasuke, Beatrice, Kazuma and Kyubey and discussed the following plans to revive Ten Tails.

Showdown between InuYasha and Tobi
On the following afternoon, Tobi and the undead jinchūrikis landed and faced InuYasha. After being beset by the jinchūrikis, InuYasha was rendered exhausted. What was left was the battle between the man who initiated Fourth Warriors War and the leading figure of the allied warriors. Seeing, InuYasha was brutalised by the Demonic Statue of the Outer Path, Jin Kariya appeared to lend support to him by facing Tobi.

Later, Bankotsu joined in the fight alongside InuYasha and Jin against Tobi. By nightfall, Tobi continued the fight. InuYasha's iron claws unmasked Tobi. Seeing the true face of Tobi when unmasked, Bankotsu and InuYasha blamed Kakashi for letting Rin Nohara die to which Jin held them back and pleaded for Tobi to come back to his senses.

With the arrival of the undead Madara Uchiha, Bankotsu demanded about Byakuya Kuchiki and Zaraki Kenpachi along with the five kages who were incapacitated.

Tobi as Ten Tails' jinchūriki
During the fight with Oda Nobunaga, Kakashi and Tobi temporarily teamed up with each other and fought the warlord. With him finished, Madara used the forbidden power, Outer Path: Samsara of Heavenly Life to drain Tobi's life. However, he proceeded to seal Ten Tails inside him before Madara becomes properly revived. Tobi as jinchūriki now annihilated the enemies such as: Meruem, Takemaru and the undead warriors.

Tobi's path to be Hokage
After the clash, Kikyo called to Goddess Vishnu to help guide Tobi on the right path. Due to Goddess Vishnu's purification, Tobi was freed from the Will of Hatred and regretted for the deaths of those he murdered in the past. As he sought to revive those he killed as penance, Zetsu appeared and drained Tobi's life thus allowing Madara to become a living being. Weakened after the Demonic Statue of Outer Path was painfully extracted from him, Tobi was now left to fight the enemies led by Madara who became jinchūriki stole rinnegan.

With both rinnegan acquired, Madara as jinchūriki now activated Rinne-Sharingan and at last started a large-scale genjutsu and ended the war, leaving an incapacitated Tobi, Kakeru Satsuki & his group, Dark San, Yue, Suigintou and some other warriors were spared.

With Madara betrayed by Zetsu and Kaguya's defeat, Tobi brought back the warriors to the real world where the tailed beasts, undead warriors, Hagoromo Ōtsutsuki, the near-dying Madara who was deeply depressed due to the Eye of the Moon Plan failed thus allowing him and Hashirama to reconcile before death.

After the sun rose, Yurika Nijino restored Tobi's energy. For his assistance in the fight against Kaguya and Madara, Kakashi now allowed Tobi to be Hokage. And now he was made Hokage for the rest of his life.
