Dotō Kazahana

Doto Kazahana is the leader of the Land of Snow and the primary antagonist of Naruto the Movie: Ninja Clash in the Land of Snow

Background
Doto started the revolt in the Land of Snow in search of a treasure which resulted in him killing his brother Sousetsu Kazahana, the daimyo. His niece Koyuki Kazahana fled from the Land of Snow and became an actress named Yukie Fujikaze.

Plot overview
The train he was on was responsible for killing off Sandayu Asama and the other rebel ninjas until it was taken out by Team Kakashi. Though he returns in his blimp where Nadare successfully snatches Koyuki. When Doto finds out that the necklace Koyuki is wearing turns out to be a fake, she suspects that Kakashi Hatake switched them while she was sleeping. Thus, Doto plans to set a trap at his castle. When Naruto Uzumaki raided the blimp to rescue Koyuki, Doto's followers easily took him and his Shadow Clones down. Doto is persuaded to use his Chakra Negator device on Naruto.

When Kakashi, Sakura, and Sasuke rescue them, they are confronted by Doto. Koyuki then gives the necklace to him before stabbing him. This failed as is wearing the "newest prototype" of Chakra Armor (which is black, as opposed to the gray versions that his subordinates wear) underneath his robe. When he does make off with Koyuki in the climax, her necklace turned out to be a key that activates a generator that would lead to the transformation of the Land of Snow into a Land of Spring, much to his dismay as he thought it was material treasure. When Naruto caught up, Doto managed to knock Naruto though the ice of the lake they were standing on, causing him to sink beneath the waters. Sasuke suddenly shows up and manages to damage the armor before being defeated.

With the Nine-Tailed Fox Chakra recovering him, Naruto emerged from the lake with the Chakra Negator fractured allowing him to summon his clones. Frustrated by Naruto's persistence, Doto tries to hit him with full power of his chakra armor, Naruto however manages to avoid it and get his Rasengan formed. Out of power due to his last attack, Doto feebly tries to punch at Naruto but only hits his clone before he hit directly by Naruto's Rasengan, enhanced by the Rainbow Chakra, breaking his chakra armor and throwing him with great force onto one of the Generator Walls. Breaking the ice covering it and allowing spring to briefly come to the Land of Snow (ironically fulfilling Kazahana's wish). Whether this was the death of him was not confirmed.

Abilities
While it is unknown how proficient a battler he is due to his single desire to be a ruler, Doto has shown access to some very powerful ice-based jutsu. He has also shown to be quite strong physically from how easily he crushed Kakashi's fake crystal. Besides fighting abilities, Doto has proven to be a very crafty and manipulative man. He is further shown to be rather adept in developing strategies and planning things out with great detail from how he prepared for Team Kakashi's attack.
