DANZÔ SHIMURA'S Background

DANZO SHIMURA'S BACKGROUND-

Danzō was once friends with Hiruzen Sarutobi as early as his childhood, and despite his best
efforts, Danzō always felt inferior to Hiruzen. During the First Shinobi World War , Danzō, along with his team-mates, Kagami Uchiha and Torifu Akimichi, as well as Hiruzen and his team-mates, Koharu Utatane and Homura Mitokado, formed a squad led by the Second Hokage. At some point, the team was pursued by enemy Kumogakure ninja. They realized that one of them would need
to distract their pursuers, and that whoever did
so would die. Hoping to die for his companions,
just as his father and grandfather had,Danzō tried to volunteer but was paralysed with fear at
the prospect of his death. Hiruzen volunteered
before he could compose himself. Angry that
Hiruzen had once again beaten him, Danzō began to protest, but Tobirama decided to be the decoy
instead. Before leaving, Tobirama appointed
Hiruzen as the Third Hokage.

With Hiruzen having beaten him to the title of
Hokage, Danzō began planning to someday attain the title himself. To that end, he created the ANBU subsidiary named Root.[2] Although the group was later officially disbanded, it remained
secretly active. During the Third Shinobi World War, Danzō agreed to help Hanzō of Amegakure in order to receive help in claiming the title of
Hokage. He sent some of his forces to deal with
the Ame Orphans but they were all wiped out by Nagato. He would later betray Hanzō at some point in history.

After the Nine-Tailed Demon Fox attacked Konoha, Danzō was one of the elders to suspect that the Uchiha clan was involved in this incident and supported relocating the clan to a secluded
area of the village where they could easily be
monitored. When word reached Konoha's
leadership of a planned coup d’état by the Uchiha clan, Danzō took advantage of Itachi Uchiha's pacifist tendencies and convinced him to provide
him and the other elders with information of the
clan's actions. When Hiruzen's attempts to end
the coup diplomatically failed, Itachi was ordered to wipe out the Uchiha clan. However, Itachi refused to kill his younger brother, Sasuke Uchiha, and threatened to share everything he knew about Konoha with rival countries if Danzō ever harmed Sasuke. He met with Madara Uchiha around this time for as yet unknown reasons. [4] At some point after Shisui Uchiha was killed, Danzō implanted Shisui's right Sharingan and arm into his own body. He also worked with
Orochimaru to implant Hashirama Senju's DNA into his right arm, modifying his physical energy. Madara speculates this was done to allow Danzō to use his eleven Sharingan at once, with the
additional effect of allowing Danzō to use Wood Release ninjutsu and ultimately the forbidden dōjutsu: Izanagi.
