Hiruzen Sarutobi

was the. Together with Homura Mitokado and Koharu Utatane, he was the student of the first two Hokage, Hashirama Senju and Tobirama Senju, and the teacher of Jiraiya, Tsunade, and Orochimaru.

Background
As a child, Hiruzen was a prodigy who truly stood out in talent. He and his former teammates, Homura Mitokado and Koharu Utatane, were students of Tobirama Senju, who would eventually be chosen as the Second Hokage. He had somewhat of a rivalry with Danzō Shimura ever since the they were children, but Hiruzen always managed to pass milestones before Danzō. During the First Great Shinobi World War, Hiruzen, the rest of Team Tobirama, Danzō, Kagami Uchiha, and Torifu Akimichi were being pursued by enemy Kumogakure ninja. Knowing that one of them would need to distract their pursuers, a task that would result in their death, Hiruzen volunteered. Tobirama chose to be the decoy instead, but before leaving he appointed Hiruzen as the Third Hokage.

Later in his life, Hiruzen became the teacher of Jiraiya, Orochimaru, and Tsunade, who would go on to become known as the Sannin. In time, he became the father of two children, Asuma Sarutobi and one who has yet to be seen in the series. This unnamed child would later give Hiruzen a grandson: Konohamaru Sarutobi.

While Orochimaru was his student, Hiruzen came to appreciate Orochimaru's natural talent, and often told Jiraiya to be more like him. He also came to recognize an inner malice and a lust for power within Orochimaru, and tried to steer his student away from these personality traits. After serving as Hokage for many years, Hiruzen started looking for a successor to the title. While he hoped to be able to give the position to Orochimaru, it became apparent that Orochimaru was only interested in the role of Hokage for the power it offered. His first choice was Jiraiya, but due to Jiraiya's journeys, Hiruzen instead passed on the role of Hokage to one of Jiraiya's pupils: Minato Namikaze.

Soon afterwards, Minato sacrificed his life to seal the Nine-Tailed Demon Fox within his newborn son, Naruto Uzumaki, forcing Hiruzen to reassume the role of Hokage. He saw to it that the orphaned Naruto would be safe by keeping the identity of his father a secret. After reacquiring his title, Hiruzen began investigating a number of disappearances within Konoha. Upon reaching the source of the abductions, he found Orochimaru to be the one responsible. Having used those that he kidnapped as test subjects in his quest to gain immortality, Orochimaru allowed his former master a chance to kill him. Ultimately, Hiruzen was unable to bring himself to kill his former prodigy, allowing Orochimaru to escape.

Hiruzen was one of four Konoha elders involved in the massacre of the Uchiha clan. He tried to find a peaceful alternative, but negotiations fell through and, against his wishes, Itachi Uchiha was ordered to wipe out the Uchiha. Itachi proved unable to kill his brother, Sasuke Uchiha, so Hiruzen promised to keep Sasuke safe.

Personality
Due to the long life he had lived, Hiruzen served as a source of wisdom for much of the series, passing on the things he had learned to the next generation. As Hokage, he had also acquired a habit of attempting to end things peacefully, and did what he could to avoid bloodshed amongst his allies and his enemies. At the series' start, Hiruzen was one of the few people who saw Naruto as more than the container of the Nine-Tails, and, as such, became someone that Naruto truly admired, even thinking of Hiruzen as a grandfather-figure.

Despite his standing as Hokage, he seemed to have had some sense of lecherousness in him, as he spent much of his free time talking to young girls. When Jiraiya was still his student, he offered to help Jiraiya test the jutsu that would allow the user to spy on naked women unnoticed. Even Jiraiya, in this instance, noted his sensei's perverted qualities. He also fell victim to Naruto's Sexy Technique on more than one occasion.

Appearance
Hiruzen is one of two known Kage to always wear the official Kage uniform, the other being the Fourth Raikage. Since his time training Jiraiya, Tsunade, and Orochimaru, he has had a small goatee and short spiked hair, both being dark brown. He also has lines running vertically under each eye. Although an old man, age has not taken much of a toll on his appearance, as it has on his skills, as it would only appear to have given him some grey hair and very few liverspots. With age it would seem that he has also taken on smoking a pipe. When in combat he wears a black jumpsuit with grey shoulder armor a gauntlet on his right arm and Leaf forehead protector bandanna with really long straps and a ninja helmet which he wears under it or it's a part of the bandanna.

Abilities
Hiruzen was one of the most powerful shinobi in history. In fact, he was so immensely powerful that he was admired as the in his prime. According to Iruka, he was said to be the strongest Hokage Konoha ever had. Enma commented on his battle with Orochimaru, saying that it was "miserable" compared to his prime, even though he had clearly been able to hold his own against Orochimaru and two former Hokage without losing his composure. He was also the longest living and longest reigning Hokage, and apparently had an undefeated streak, having defeated all foes that came before him until he sacrificed himself in order to stop Orochimaru.

Jutsu
Hiruzen was called, due to his mastery of all forms of shinobi combat, and his vast knowledge of jutsu, purportedly knowing all the techniques within Konoha. The first technique he was seen using was the Telescope Technique, which allowed him to observe others through his crystal ball over long distances. With Roof Tile Shuriken, he could launch nearby tiles at an opponent with varying intensities, and by throwing a single shuriken at an opponent, he could replicate it to surround the opponent through Shuriken Shadow Clone Technique.

The more battle-oriented techniques he was seen using primarily consisted of elemental attacks, as he had an affinity for fire and earth. Fire Release: Fire Dragon Flame Missile allowed him to exhale a stream of fire from his mouth. Earth Release: Earth Flow River created a river of mud beneath the opponent to throw them off balance, and he could use the mud with Earth Release: Earth Dragon Bullet, which creates a dragon's head that launches mud balls at an opponent. He had also been shown to be adept in elemental collaboration jutsu, as seen when he ignited the mud ball projectiles with Fire Release: Fire Dragon Flame Missile, creating a stream of lava that can melt nearly anything. Earth Release: Earth Style Wall allowed Hiruzen to spit a stream of mud that solidifies into a protective shield.

Orochimaru showed some surprise that he didn't use more of the Shadow Clone Technique during their battle. An ANBU agent watching the battle scene from nearby mentioned that Hiruzen's chakra levels had dropped to a point where he couldn't use it as much. While this might contradict the large amount of techniques he used in his battle with Orochimaru, it could also show his great chakra control, needing only the minimum amount of chakra to use each technique.

Taijutsu
Despite being a man of very accumulated age, he still was able to display considerable striking power, such as in the fight with Orochimaru, using the Enma Pole to smash through even Hashirama's Mokuton successfully and besting even Orochimaru, who was armed with the Kusanagi.

Summoning Technique
Hiruzen also had a personal summon: Enma, the Monkey King. Enma could turn into a diamond-hard staff, which could alter its length and width at will. This staff was Hiruzen's weapon of choice, and he showed great proficiency in wielding it.

Invasion of Konoha arc
When the invasion began, Hiruzen was forced to battle Orochimaru, who infiltrated the village and planned Konoha's destruction just so he could kill Hiruzen and kidnap Sasuke Uchiha. Soon after the battle began, Orochimaru resurrects Hashirama and Tobirama, so that Hiruzen could feel the enjoyment of fighting his former masters. In his old age, Hiruzen was unable to be much of a match for the two Hokage, and was further inhibited by his desire to not hurt either. Orochimaru's presence also impeded Hiruzen's fight, as seeing just how monstrous his treasured student had become broke his heart. Although he used his summon, Enma, to help him in battle, Hiruzen was unable to defeat the two Hokage, as any damage that was done was simply regenerated.

Having no other choice, Hiruzen used a combination of shadow clones and the Dead Demon Consuming Seal to seal away the souls of his former masters. As he bid a heartfelt goodbye to his teachers, he turned his attention to Orochimaru. Charging at Orochimaru, and throwing aside his former pupil's Kusanagi, Hiruzen attempted to seal Orochimaru's soul as well. Sensing what Hiruzen was trying to do, Orochimaru called his Kusanagi to him, stabbing Hiruzen in the back.

Despite the fatal injury, Hiruzen continued to try to remove Orochimaru's soul, unconcerned with the sword in his back, due to death being guaranteed as a result of using the Dead Demon Consuming Seal. After an hour passed, Hiruzen came to terms with the fact that he was too old and weak to completely remove Orochimaru's soul. Doing what little he could, and hoping to rectify his mistake of allowing Orochimaru to escape years earlier, Hiruzen sealed Orochimaru's arms, to ensure that he would never again be able to use jutsu, a punishment for Orochimaru's obsession with power.

As Orochimaru began to curse his former master for what he had done, Hiruzen bid Orochimaru farewell, and expressed the hope that they would meet again. Knowing that the village was saved, and seeing Orochimaru as the boy he once was, Hiruzen died with a smile on his face.
