The Copy Ninja Kakashi Hatake
Kakashi Hatake is a fictional character and one of the main protagonists in the Naruto manga and anime series created by Masashi Kishimoto.Kakashi is depicted in Naruto as an eccentric but highly skilled shinobi for the Hidden Leaf Village.
Initially cold and calculated due to the suicide of his father, Sakumo, Kakashi eventually began to warm up in his youth with the help of his teammate Obito Uchiha, while they are under the tutelage of Naruto's father Minato Namikaze. It is through Obito that Kakashi obtains the Uchiha clan's Sharingan, which he
uses to copy the abilities of his opponents and make his own, but also drains his energy. Kakashi is one of the most well-respected characters in the ninja world. Not only is he held in high regard in Konoha but he's also held in legendary light across all the shinobi Nations. This is evident from the various instances where just a glimpse of his face told people that he was Konoha's Copy Ninja.
Anbu black cops
During Kakashi's membership in the Konoha's elite ANBU program, he becomes assigned to various missions. Aside from a new outfit, Kakashi's membership into the ANBU means he's become part of Konoha's mysterious black ops shinobi team. However, unlike other ANBU, Kakashi would become a member of Team Ro, the Hokage's personal black-ops unit. In Team Ro, Kakashi would often partake in "the black" - missions that include not just investigation and infiltration, but also assassination.During his membership, Kakashi would eliminate hostile shinobi from various Lands and Villages. Likewise, Kakashi and Team Ro would participate in Itachi's elimination of the entire Uchiha Clan. While they wouldn't lay a hand on the Clan itself, Team Ro would intercept the Clan's coup, treat sole survivor Sasuke Uchiha, and even dispose of the Uchiha Clan's corpses.
Team 7
Kakashi known as best of the mentor of Konoha 11's Team 7. In this team, Kakashi would mentor Sasuke, Naruto Uzumaki, and Sakura Haruno. It seems the Third Hokage at the time handpicked Kakashi's members given his relationship to Minato and involvement in the Uchiha Clan Massacre. In turn, the Third Hokage deemed Kakashi fit of not just honing the skills of Team 7, but also unite them. Whereas Kakashi introduces Naruto to Jiraiya (who will eventually teach Naruto the Rasengan), he mentors Sasuke and teaches him the Chidori.
Despite the strong wills of his students, none of them would ever make it to Chunin rank. Moreover, Sasuke's desire for power and vengeance would lead him to defect to Orochimaru. However, despite these failings, Kakashi would instill a sense of teamwork and loyalty to his students, something Minato also passed down to him.In Part 2, Kakashi would submit documentation to Hokage Tsunade to rename Team 7 into Team Kakashi. His team would comprise of members Naruto and Sakura, albeit this time treated as his equals.
6th Hokage
Hashirama Senju created Konoha with the aim of achieving peace and protecting children from dying in wars. Despite creating the village and establishing himself as the Hokage, he failed to accomplish all his goals. Just like him, most of his successors failed to achieve peace as well, until the 4th Great Ninja War finally saw all nations collaborate.
Kakashi Hatake's time as the Sixth Hokage saw the world remain largely at peace. It goes without saying that his time as Kage was the most peaceful out of all the known Kage in the village's history. Even his successor, Naruto Uzumaki, couldn't maintain peace as the likes of the Otsutsuki and Kara started their attacks soon after.
