Decades before the start of the
series, Hashirama struck a
peace treaty with the Uchiha
and its then-leader, Madara
Uchiha, and together the two
clans created the Hidden Leaf Village. When Hashirama died,
Tobirama was appointed as the
Second Hokage. During his
reign he was primarily
responsible for establishing
Konoha's organisational system. He established various
organisations such as the Ninja
Academy, the ANBU, the
Chunin Exams and the Leaf's
Military Police Force, the latter
of which he created as a sign of trust towards the Uchiha
who made up the majority of
that organisation. However,
according to Tobi, the Police
Force was actually established
to distance the Uchiha from the government of the village and
place the clan under a tight
surveillance by the ANBU. At
some point during his tenure,
he and the Second Raikage met
to form an alliance between the Hidden Leaf and Hidden
Cloud villages. However,
Kinkaku and Ginkaku, the
Cloud's Gold and Silver
Brothers, attempted a coup
d’état against the Second Raikage and were defeated by
Tobirama, who was left near
death after the fiasco. He also trained a three-man
team of his own, Team
Tobirama, which consisted of
Hiruzen Sarutobi, Homura
Mitokado, and Koharu Utatane. During a mission in the First Shinobi World War, on which
Team Tobirama performed with
Danzo Shimura, Kagami Uchiha
and Torifu Akimichi, they found
themselves surrounded by
twenty elite Cloud ninja, known as the Kinkaku Force. Tobirama then realised that the
only way any of them could
escape alive was for one of
them to be a decoy and
sacrifice themselves. Therefore, having faith that he had
trained his students well, he
chose to sacrifice himself after
he selected his prized student
Hiruzen for the position of
Third Hokage. Homura and Koharu would later become
Hiruzen's advisers. After giving
the title of Hokage to Hiruzen,
Tobirama went off to fight the
enemies where he died a noble
death. As the Second Hokage,
Tobirama was hailed as one of
the most powerful shinobi of
his era and was also the creator
of the Summoning: Reanimation
technique; however, some time after its creation he labelled it
as a forbidden jutsu and never
mastered it himself, though he
did use it enough for it to be
recognised by other Kage. By
simply touching the ground with his index finger, he could
detect the presence and number
of enemy shinobi. Tobirama
was primarily known for his
mastery of Water Style. He
could perform powerful water- style techniques in areas that
lacked bodies of water by
creating his own water out of
thin air or producing it from his
mouth, and perform some of
the most complex water-style techniques, such as the Water
Release: Water Dragon Jutsu,
with a single hand seal. This,
among other reasons, is why he
is revered as the greatest
known Water Style manipulator in the series.
