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 encountered Naruto Uzumaki, and they fought. They both ended up at a draw, and fell off a cliff. He later woke up next to Naruto, after having been treated. He then continued to travel with the caravan he had woken up on for a short time. He wanted to show his master, Haido, who Naruto was. After the introduction, he was sent on a mission, but his plan was found out by Naruto. After some fighting, he managed to escape. He was hunted down by both enemy and ally until he fought Haido after discovering that he was the murderer of his family, but was easily defeated. He, alongside Naruto, performed Twin Rasengan to finish off Haido. He saved his new friends from the collapsing castle, and was saved by Naruto whilst falling to his death. He discovered a prophecy had foretold him and Naruto defeating Haido as friends. As Temujin left for a new land, he crossed paths with his new friend, Naruto, where they promised to meet again.

Abilities
Wishing to be of use to Haido, Temujin trained hard to become a powerful fighter. 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 reflexes, 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 large-scale damage, and equals the raw power of Naruto's Rasengan.

Trivia

 * Temujin is the heir to the main branch of his clan.
 * 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 of 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, along with 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.
