Kakashi hAtake's BackGround

KAKASHI HATAKE'S BACKGROUND -

Kakashi is the only son of Sakumo Hatake, also known as the "White
Fang of Konoha". His
mother apparently died
when he was young.
Kakashi has been known
since a young age as an extremely gifted prodigy,
regarded by many as the
best of his generation. He
had received top marks
and had shown an innate aptitude for the ninja arts while in the academy.
This permitted him to graduate from it in a single
year at the top of his class at the age of 5, and then
becoming a chūnin a year later.

Despite his own success, his father fell into
disgrace after choosing to save his comrades
rather than complete an important mission, causing
Konoha to suffer in the war effort. Dishonoured,
Sakumo took his own life after a deep depression
and a drop in his skills, which caused Kakashi to lead his life strictly by the ninja code.

After graduating,
Kakashi was then
teamed with Obito Uchiha and Rin under the
leadership of Minato Namikaze, the future Fourth Hokage. Kakashi's relationship with
Obito and Rin was
noted to be very
similar to that of Sasuke's relationship with Naruto and Sakura respectively, as he is known as the indifferent genius who shared a complicated
relationship with his team-mates, that later
developed into a close friendship. Years later
during the Nine-Tails' Attack on Konoha, he along with the rest of his peers were barred from
participating in the defence of the village by
Kurenai's father and other older shinobi.

KAKASHI GAIDEN -

At the age of 13,
soon after becoming
a jōnin, Kakashi was assigned to lead
Obito and Rin on a
mission that would
benefit Konoha in the
ongoing Third Shinobi World War . They were to destroy the Kannabi Bridge, which was being used by Iwagakure forces to move into Kusagakure. This would also be Konoha's first huge offensive move
in the war. On their way to the bridge, Rin was
kidnapped by two Iwagakure ninja named Kakkō and Taiseki. Obito immediately suggested that they rescue her, but Kakashi disagreed on the basis that
they needed to complete their mission, opting not
to make the same mistake his father did. Obito
would not hear of it and stubbornly left to save
Rin, but not before mentioning that he believed
Kakashi's father, the White Fang, was a true hero. Shortly after parting ways, Kakashi reflected on
Obito's words and Rin's prior kindness. He realised
that his father was not wrong after all, which
prompted him to join Obito in the rescue effort.

Kakashi arrived in time to save Obito from Taiseki,
using his father's blade to combat him. Despite the 2-to-1 disadvantage, Taiseki was able to attack
and damage Kakashi's left eye, who took the blow
that was intended for Obito, giving him a
permanent scar. In sheer terror and desire to
protect Kakashi, Obito finally awakened his Sharingan, allowing him to see through his opponent's camouflage jutsu, kill the attacker, and
continue on to Rin. Once they located Rin and
Kakkō, Kakashi and Obito teamed up to defeat the latter. Kakashi and Obito freed Rin, but just as
Kakashi's team was about to leave, Kakkō attempted to trap them with a crushing technique, causing a cave-in.

While trying to escape, Kakashi was hit in his blind
side by a rock, causing him to fall. Obito pushed
Kakashi out of the path of a falling boulder, causing
himself to be crushed beneath it instead. Knowing
his life was at an end, Obito instructed Rin to
implant his left Sharingan into Kakashi's damaged eye. Rin complied, and as soon as the surgery was
completed Kakashi used the Sharingan and his Chidori to kill Kakkō. He then returned to Obito to see if there was anything he could do for him, but
the place was turning into shambles, forcing
Kakashi and Rin to leave him behind. With the help
of Minato, they ultimately completed their mission,
allowing them to mourn Obito's death.

Following the success of his first mission as a jōnin, Kakashi became well-known among all five great
countries for the extensive use of his Sharingan,
gaining him a reputation as "the man who has
copied over a thousand jutsu," hence his nickname.
Kakashi joined the Konoha ANBU a few years later. He later left for unknown reasons, but maintained
strong connections with the ANBU. He once had a
mission wherein one of his team-mates, Iruka Umino, was injured, paving the way for the latter to become an instructor at the Ninja Academy. When Iruka was having doubts at being assigned
to be the homeroom teacher of Naruto Uzumaki, Kakashi served to remind him of his real reasons for wanting the post in the first
place.

Kakashi eventually became a team leader, and tested many genin. As the Third Hokage told Iruka, Kakashi had never passed any of them due to their inability to live up to his expectations of
working as a team.
