Temujin

Temujin appeared in Naruto the Movie 2: Legend of the Stone of Gelel. His master, Haido, implanted a Stone of Gelel in him which allows him to manipulate Gelel Energy in a similar manner to chakra.

Plot overview
He encounters Naruto Uzumaki and they fight. They both end up as a tie and fall down from a cliff. He was then woken up with Naruto and was treated. He then went with the caravan for not a long time. He then wanted to show his master, Haido, who Naruto is. After the introduction, he was sent on a mission and his plan was found out by Naruto. After some fighting, he escapes. He is hunted down by both enemy and ally until fighting Haido after discovering he was the murderer of his family and home but is easily defeated. He, alongside Naruto, performs Twin Rasengan to finish off Haido. He saves his new friends from the collapsing castle and is saved by Naruto when falling to his death. He discovers a prophecy foretold him and Naruto defeating Haido as friends. As Temujin leaves for new land, he crosses paths with his new friend, Naruto, promising to meet again.

Abilities
Wishing to be of use to Haido, Temujin trained hard to be become a powerful battler. During his battle against Naruto, he demonstrated tremendous hand-to-hand combat prowess, being able to easily dodge multiple attacks from Naruto's shadow clones and simultaneously dispatch them. He also demonstrated great instincts, being able to dodge sneak attacks from Naruto and Shikamaru.

While under the influence of his Stone of Gelel, Temujin has regenerative powers almost as great as Naruto's and also showed surprisingly high levels of strength, easily being able to break free from most bindings. The pinnacle of his Gelel power is to unleash a tremendous stream of energy from his sword that can cause mass scale damage and equals the raw power of Naruto's Rasengan.

Trivia

 * Temujin's eyes are naturally green but they became red when the Stone of Gelel was implanted within him.
 * Temujin's character seems loosely based off Sasuke, further suggested by Naruto thinking about Sasuke near the end of the movie when Temujin was in danger. They both have shown great anger towards their pasts and a strong desire to take control of their future. They also initially looked down on Naruto and found him a bother. Temujin may also have been designed as an antithesis to Sasuke's decision of giving into his anger.
 * Temujin is the real name of the Mongolian Warlord, Genghis Khan.
