Doto Kazahana in Naruto

Doto, from the Land of Snow but later settled in Yukigakure, began a rebellion while searching for a treasure. This rebellion led to him killing his brother, Sosetsu Kazahana, who was the daimyo, or leader, of the Land of Snow then. Doto's niece, Koyuki Kazahana, fled from the Land of Snow and later adopted the actress Yukie Fujikaze's identity.

Doto is first introduced at his fortress, where he learns that Kakashi Hatake is protecting Koyuki. He then boards a train to find the princess. However, Sandayu Asama and other warriors from the Land of Snow confront the train, leading to a confrontation.

Doto uses a kunai-launching mechanism to attack the samurai, resulting in casualties. Eventually, Team Kakashi destroys the train, but Doto and his allies return later in a blimp, successfully capturing Koyuki.

When Doto discovers that Koyuki's necklace is a fake, suspicions arise. Koyuki believes Kakashi switched the necklaces while she was asleep. Doto plans to set a trap at his castle. Naruto Uzumaki and his team attempt to rescue Koyuki and confront Doto. Doto's followers overpower Naruto, leading to a confrontation where Doto intends to use a device called the Chakra Negator on Naruto.

Kakashi, Sakura, and Sasuke eventually come to rescue Koyuki, leading to a final showdown with Doto. Koyuki tries to give Doto the necklace before attempting to stab him. However, Doto was wearing a powerful Chakra Armour underneath his robe, making the attack ineffective.

It allows Doto to escape with Koyuki and he takes her to the rainbow glacier, believing it hides a great treasure that would give him an army to challenge the Five Great Shinobi Countries.

Naruto catches up with them, and after a series of battles, Doto manages to knock Naruto into a frozen lake. Sasuke arrives and damages Doto's chakra armor with his Chidori attack but is eventually defeated.

With the Nine-Tailed Demon Fox's chakra helping him recover, Naruto emerges from the lake with the Chakra Negator broken, allowing him to summon shadow clones. Frustrated, Doto tries to attack Naruto using his Ice Release: Twin Dragon Blizzard technique, but Naruto avoids getting hit and prepares his powerful Rasengan attack.

Having depleted his power, Doto attempts a feeble punch but only manages to hit a clone. Naruto hits Doto directly with his Seven-Coloured Rasengan, enhanced by Rainbow Chakra, breaking Doto's chakra armor and throwing him onto a Generator Wall, ultimately defeating him. This action breaks the ice covering the wall and briefly brings spring to the Land of Snow, fulfilling a wish of the Kazahana family.

Doto was ruthless and power-hungry. He's willing to do anything to achieve his goals, even if it means betraying his own family and causing harm to others.

Doto had long dark hair, a broad face structure, and a big nose and wore a grey cloak. He wears a black color Chakra Armour, which has a blue energy source component attached to it and wears green cloth below his waist.

Doto was a skilled shinobi who preferred to let his subordinates do the fighting, but he had impressive abilities:

Ninjutsu

Doto possessed powerful ice-based ninjutsu skills. He could manipulate ice and snow to create formidable black ice dragons to attack his enemies.

Nature Transformation

His ice techniques demonstrated his mastery of nature transformation, particularly in using ice-based attacks.

Prototype Chakra Armour

Doto wore a unique black prototype Chakra Armour, providing him with exceptional defense against ninjutsu and genjutsu. It even allowed him to withstand a Chidori attack, although it resulted in a crack in his armor. The armor also enhanced his own techniques and had built-in wings for gliding.

Other Abilities

Dotō was not just a formidable fighter but also crafty and manipulative. He excelled in strategy development and detailed planning, as seen in his preparations for Team Kakashi's attack.

Additionally, he had knowledge of foreign techniques. Dotō displayed considerable physical strength by shattering a large area of dense ice with a single powerful blow.
