NAGATO'S APPEARANCE AND PERSONALITY

NAGATO'S APPEARANCE-

Nagato was a fair-skinned man with chin-length
red hair (a colour which is a trademark of the
Uzumaki clan) with his most noticeable trait
being his Rinnegan eyes. As a child, his hair
would regularly hang off his face blocking the
view of his eyes; his normal eyes are never seen. Nagato grew into a tall man, but after subjecting
himself to the Summoning: Demonic Statue of the Outer Path, Nagato was reduced into a withered version of his former self with chakra receivers implanted into his back, one in each of his
shoulder joints and smaller ones in his forearms.
Nagato uses a mechanical walker for mobility,
which could fire Chakra Disruption Blades for personal defence. He was the only Akatsuki
member never seen wearing the organisation's
uniform, until after his death, and he ceased
wearing a slashed out forehead protector after
defeating Hanzō. However, his Six Paths of Pain wore both in his stead.

NAGATO'S PERSONALITY-
Nagato was a sensitive, but kind boy, prone to
crying, and was traumatized by the idea of killing
others, even if it was to save his friend Yahiko.
Scared and unsure of his place in the world, he
desired to help those he cared about, but never
knew how. He was consistently respectful and kind to Konan, who he claimed to be his "angel"
in Amegakure. He was shown protecting her,
without request or hesitation from Jiraiya before
his battle with his former teacher. Apparently,
she was the only Akatsuki member that
addressed him by name. He was aware of Konan's feelings towards Yahiko and left them
alone to have personal time together.

As Pain, his personality was very different,
having become a calm, serious, aloof, and
detached man. Apparently believing traumas he
experienced in his youth had enlightened him to
the true meaning of pain and suffering, he
considered himself a deity, and believed he had evolved beyond a mere human being. He sought
to show the world the meaning of pain by using
an ultimate weapon to deter future wars, by
means similar to "mutually assured destruction",
and showed no moral qualms about his actions.
He was willing to kill Jiraiya to ensure the completion of his plans. He even went so far as to
proclaim himself a "god of peace", that had to
guide the world to maturity through pain. Finally,
he felt that no-one could understand true peace
unless they understood "true" pain, something
his childhood friend Yahiko believed. Minato Namikaze believed Madara Uchiha to have been using this philosophy in his favour, in order to
manipulate Nagato.

In the anime, Nagato is shown to be sensitive
when it comes to talk about "pain"; when Ibiki Morino used a special summoning jutsu that "linked them by pain" Nagato got furious
(through the Animal Path) and shouted that "he
had no idea of what true pain was" releasing
itself from the jutsu and attack Ibiki violently.

Nonetheless, he was seen to be quite respectful,
particularly to the fallen and the dead. Given the
Akatsuki members' frequent bickering, he often
quelled them and encouraged better relations
among members. He even suggested that they
mourn for Deidara after his passing, and reprimanded Kisame for calling Hidan and Kakuzu the "Zombie Brothers". After his battle with
Jiraiya, he held a moment of silence for his former
teacher, out of respect for his power. Because Konohagakure was partly responsible for the tragedies in his life, he held some form of
animosity for the village. Although Jiraiya's
influence improved his opinion of the village
during their time together, he eventually came to
believe that Konoha profited from the tragedies
of others and hated it and his former teacher.
