This naruto papercraft is the Nagato (Pain), the paper craft model is created by rexxkentrix. Nagato, also known as Pain (Pein), was the recognised leader of Akatsuki and Amegakure and a major antagonist of the series. Referred to as "Leader" by all Akatsuki members, he directed the actions of the rest of the members and maintained authority over them. Later it was revealed that he had secretly collaborated with Tobi who was the real leader of Akatsuki.
According to Tobi, Nagato was a descendant of the Uzumaki clan. During the Second Shinobi World War, Nagato lived with his parents in a village somewhere near Amegakure. One day, two Konoha shinobi broke into their home, looking for food, unaware that the place was still inhabited. Nagato's parents, believing they were going to be killed, attacked the two so that Nagato could escape. Having mistaken them to be enemy ninja, the Konoha ninja killed his parents. In his grief, Nagato awakened his Rinnegan for the first time and killed the assailants. He came to consider this incident as the first great pain of his life.
With his family gone, Nagato wandered the country, going from house to house asking for food. In time he met a dog named Chibi and, later, met Konan and Yahiko, who began travelling with him in his search for food. One day, Chibi was killed in the crossfire from Hanzō's fight with several Konoha shinobi. Nagato and the other orphans later mourned its death. When the war ended, the three orphans ran into the Sannin and after hearing Yahiko's plea, rather than return to Konoha with his team-mates, Jiraiya decided to teach the three how to look after themselves.
Soon after Jiraiya began living with the orphans, Nagato and Yahiko were attacked by an Iwagakure ninja. Nagato reactivated his Rinnegan to defend Yahiko, killing the ninja. When Jiraiya found out about this, he decided to train them in ninjutsu. Nagato was very emotional about killing the ninja, and asked Jiraiya for help so he could protect Konan and Yahiko. Jiraiya's response was for Nagato to grow up and to use his eyes to find the peace that they both desired for the world. Three years later the orphans had become competent ninja, so Jiraiya returned to Konoha.
Over the years, news of the three's exploits would reach Jiraiya which often consisted of the death of someone who opposed them; eventually he received word that they had all died. In truth, Nagato, Konan, and Yahiko began a quest to find peace, by forming the organisation Akatsuki with Yahiko as its leader. They became full-fledged Amegakure ninja and gathered followers who shared their philosophies of an end to war.
Hanzō, the leader of Amegakure, viewed the group as a threat to his rule and schemed with Konoha's Root to eliminate them. Claiming to want to discuss peace, Hanzō lured Nagato, Yahiko, and Konan to an ambush. There he forced Nagato to choose between killing Yahiko or Konan. Not wanting to force Nagato to make the choice, Yahiko impaled himself with a kunai that was placed in Nagato's hand. With Yahiko's dying breath, he told Nagato to survive, because he believed in Jiraiya's words that Nagato would become the world's saviour. This incident would become the second great pain of Nagato's life.
Devastated, Nagato retrieved Konan and Yahiko's body and launched an attack on Hanzō's men. With the Summoning: Demonic Statue of the Outer Path he was able to kill all but Hanzō. However, the technique left Nagato emaciated, with numerous chakra rods embedded in his back; Hanzō's trap also injured Nagato's legs, which crippled his mobility for life. He severed his loyalties with Amegakure by scratching through the symbol of his Amegakure forehead protector, resolving to teach the village and the world his pain. Yahiko's body would later be incorporated into the Six Paths of Pain as the Deva Path. Nagato took over as leader of Akatsuki in Yahiko's stead.
Upon adopting the alias "Pain", Nagato led the rebelling forces in the Amegakure civil war, and took control of the village by assassinating Hanzō while using his Six Paths of Pain. He then solidified his leadership by systematically killing anyone who had ties to the former leader.
Nagato was a fair-skinned man with chin-length red hair 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 to an emaciated version of his former self with chakra receivers implanted into his back, one in each of his shoulder joints, smaller ones in his forearms and two metal-like screw under his collar bones, near his shoulder joint. 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. After Nagato used the Outer Path: Samsara of Heavenly Life Technique to revive all the Konohagakure citizens that had been killed during his invasion, his red-hair turned pure white due to the overexertion of his chakra. When reincarnated by Kabuto, Nagato was left in the exact state as he died - emaciated and with white hairs. The only exception were black rods that are no longer attached to his body. However, after Nagato uses his ability to absorb chakra from B Version 2 form, this chakra seemingly revitalises Nagato's body, restoring his muscle mass and restoring his hair colour from white back to the Uzumaki clan's characteristic red colour.
Nagato was a sensitive, kind boy, prone to crying, and was traumatised 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 became 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 Tobi to have been using this philosophy in his favour, in order to manipulate Nagato.
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 Combo". After his battle with Jiraiya, he held a moment of silence for his former teacher, out of respect for his power, and even told Zetsu to praise the latter.
Because Konohagakure was partly responsible for the tragedies in his life, he held a great deal of animosity towards 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.
After his reincarnation, Nagato has shown to be kinder and carefree to the point he was even willing to start making jokes, something which surprised Naruto. His opinion of Naruto also strengthened after he last saw him, pointing out to Itachi Uchiha that he wasn't surprised that Naruto was able to advance his control over the Nine-Tailed Demon Fox since they both had studied under the same master.
As the leader of Akatsuki, and one of the two sides of the Amegakure civil war, Nagato was an extraordinarily powerful shinobi, and recognised as the most powerful member of Akatsuki. His partner, Konan, had stated that he had never lost a single battle, and that he is "unbeatable". Fukasaku stated that without understanding Pain's power, no one could beat him, and even Tobi noted that Nagato was invincible while praising Jiraiya. Nagato even killed Jiraiya with relative ease, after revealing all six of his bodies. In praising his former teacher, Nagato attributes his ability to defeat Jiraiya to the secret of his Six Paths of Pain and the fact that he underestimated Jiraiya's level of genjutsu usage, stating he would not have won if Jiraiya had uncovered the secret behind his Six Paths of Pain technique. Zetsu expressed shock when Nagato was defeated by Naruto, stating he never thought Nagato would ever lose even in a weakened state. After being reincarnated by Kabuto Yakushi, he was able to easily overwhelm both Naruto Uzumaki and Killer B, despite Naruto being in his Nine-Tails Chakra Mode and Killer B having perfect synchronism with his tailed beast. He would have killed them both had it not been for the intervention of Itachi Uchiha while Kabuto was preoccupied with them. It took the combined efforts of Naruto, B, and Itachi to successfully defeat Nagato in the state of control Kabuto had him under. As a member of the Uzumaki clan, he also possessed the potential for incredible longevity. It has been noted at several points in time that Nagato possessed an unusually large amount of exceptionally strong chakra, to the point of after he decimated entire Konoha and fought Naruto Uzumaki, he still had enough strength to revive all of the people he had killed in Konoha.
Nagato's legs were greatly damaged in a battle against Hanzō. As a result, even though he can stand up by himself, he can't move as quickly. To make up for this while alive, Nagato used the Six Paths of Pain to fight for him while he stayed in one place in a mechanical walker. When he was reincarnated by Kabuto, he used various summons to move around and to keep himself out of range of the opponents' attacks.
