Name: Kakashi Hatake
Jutsu(s): Too many, sharingan, mangekyo sharingan
History:Like his father, Sakumo Hatake whose skills have been compared to that of the Legendary Ninja, Kakashi is considered a genius shinobi, graduating from the Ninja Academy at age 5 and achieving the rank of Chunin at 6. A few years after these accomplishments, Kakashi's father was disgraced by the village for abandoning a mission in favor of saving his comrades, which cost the Land of Fire dearly. Deeply ashamed and ostracized even by those he had saved, Sakumo committed seppuku, leaving Kakashi to bear witness to the event. After his father's suicide, Kakashi began to adhere strictly to the rules of the shinobi – in particular the rule dictating that the success of the mission must come before the well being of one's teammates, causing him to become arrogant, humorless, and by-the-book.
At the age of 13, Kakashi achieved Jonin status. As a reward for his accomplishment, he was assigned to lead his team on a sabotage mission to blow up a bridge in order to prevent enemy forces from attacking Konoha. Shortly after the mission started, Kakashi's teammate, Rin was captured by enemy shinobi. Kakashi's other teammate, Obito Uchiha immediately stated his intention to save her, but Kakashi said they had to focus on completing the mission, opting not to make the same mistake his father had. Though Kakashi believed that they had to complete their objective and they parted ways, a little reflection on Obito's words and Rin's prior kindness eventually convinced him that his father had done the right thing in saving his teammates. This revelation prompted Kakashi to turn back to join Obito in the rescue effort, although he initially claims that he did not believe Obito could survive on his own—a statement that is more or less supported by how his arrival coincided with saving his oblivious teammate from a ninja's attack.
During their attempt to save Rin, Kakashi lost his left eye as a result of taking an enemy ninja's attack for Obito. To protect Kakashi in return, Obito managed to awaken his Sharingan and killed their assailant. Soon after saving Rin, a rockfall technique was triggered and a rock struck Kakashi on his blind side. He would have been buried beneath the rocks had Obito not pushed Kakashi out of the way, getting the right side of his body almost completely crushed in the process. Shortly before he died, Obito had Rin (a medical ninja) implant his Sharingan eye in Kakashi's damaged eye socket as a gift. As his first act with his new eye, Kakashi avenged Obito by killing the enemy ninja with his now-perfected Chidori technique, bringing the Kakashi of today into being.
Years later Kakashi would become a member of the Konohagakure ANBU where he served as a squad leader. During this time, he had several kōhai, named Yugao Uzuki and Tenzo, and recognized the latter as the most successful of his kōhai. It is unknown when or why he left ANBU, but he still wears his gloves, a characteristic of ANBU uniforms.
