Shepherd Ju Peter

Saint Shepherd Ju Peter is a member of the Five Elders, who are the heads of the World Government. He possesses the title of "Agriculture Warrior God".

Along with the other Elders, he is an overarching antagonist of the entire One Piece series, being one of the primary antagonists in the Final Saga.

Appearance
Ju Peter looks considerably younger than the other Elders, having blonde hair and no wrinkles. He has a short mustache and beard, and is rather tan. He wears a very dark maroon suit and pants, and under his suit is a white collared shirt. He lacks a tie, and his shirt's collar is very low, exposing much of his chest. He has a scar on his chest going down from his lower neck toward his right armpit.

Personality
Like the other Elders, Ju Peter cares about the balance in the world maintained by the Three Great Powers and wishes to maintain it; he expressly wishes to prevent the chaos that would arise from such a downfall. He has been shown to give great thought regarding the impacts of vacancies in both the Seven Warlords and Four Emperors. He also wishes to preserve the image of the World Government by keeping the events of the Void Century a secret, and he and the other Elders will immediately have anyone destroyed who is found to be studying it; notably, Ju Peter was the one who gave the order to kill Clover, doing so while the archaeologist was still discussing his findings. Like the other Elders, he has little tolerance for people of lower rank challenging their authority, as shown during the Elders' meeting with Marine Fleet Admiral Sakazuki.

Ju Peter is quite knowledgeable regarding the Hito Hito no Mi, Model: Nika and takes its threat quite seriously. When Walcury questioned its existence, Ju Peter quickly countered his assertion with the strong belief that past actions regarding the fruit guaranteed that the World Government intended it to be erased from history, expressing this view very passionately.

Abilities and Powers
As a member of the Five Elders, Ju Peter is one of the few to have the "highest authority of the World Government", being above even the World Nobles. He has control over every facet of the World Government, including the police, the Marines, and Cipher Pol, and even the Fleet Admiral of the Marines is incapable of challenging his power. As a result, he has authority to declare a Buster Call, and he and the other Elders can use their great degree of power to manipulate the media and withhold facts from the general public, including erasing entire segments of history, most notably the Void Century. The only known person who seems to outrank the World Nobles is Imu.

Transformation
Ju Peter has an ability that allows him to transform into a giant creature with a large mouth. In this form, he could withstand a point-blank blast of fire from Sabo without difficulty. It is unknown if this power is related to a Zoan-type Devil Fruit.

Weapons
Ju Peter carries a flintlock, which he intended to use to execute Nefertari Cobra for seeing Imu.

Past
As recognition for his genius inventions in MADS, Dr. Vegapunk was invited to Mary Geoise for an audience with the Five Elders.

Twenty-two years ago, the Five Elders spoke via Den Den Mushi to Professor Clover, an archaeologist from Ohara who was revealed to have been studying the Poneglyphs. Clover revealed that he knew too much about the Void Century, and Ju Peter immediately ordered for the Cipher Pol unit on Ohara to eliminate him. The Five Elders then gave the command for a Buster Call to destroy Ohara and its historians.

Jaya Arc
A Marine came to the Room of Authority to report that Shanks had made contact with Whitebeard. However, the Five Elders' top priority was finding a replacement for Crocodile in the Seven Warlords of the Sea, with Ju Peter saying that they could not allow the Three Great Powers to crumble.

Long Ring Long Land Arc
The Five Elders got a call that Marine Admiral Aokiji had gone off on his own.

Post-Enies Lobby Arc
The Five Elders received a report that Shanks had successfully met with Whitebeard himself, to their shock.

Post-War Arc
The Five Elders talked about the aftermath of the Battle of Marineford, and said to wait for pirates to emerge in the changing New World when considering potential new Warlord candidates. They then talked about Blackbeard's rise to power, and Ju Peter said that little could likely stop him aside from the other Emperors and the remnants of the Whitebeard Pirates.

Dressrosa Arc
Fleet Admiral Sakazuki came to the Room of Authority to question the Five Elders about why they let Donquixote Doflamingo use the World Nobles' authority to misinform the entire world. The Elders reminded Sakazuki of his place and reprimanded his insolence, with Ju Peter stating that the matter had been entrusted to Cipher Pol. A Marine then came in and revealed that Luffy and Trafalgar Law's alliance had taken down Doflamingo, and that their victory had been broadcast to the entire world, shocking the elders and Sakazuki.

Levely Arc
As the Levely was beginning, the Five Elders were approached by Shanks. Because of his position, they reluctantly allowed him to talk to them about a certain pirate. After meeting with Shanks, they headed toward the Empty Throne, and talked about how king Nefertari Cobra of Arabasta had requested to meet with them. Upon reaching the Empty Throne, they knelt before its occupant Imu as they requested that Imu tell them the name of the "light" that needed to be extinguished from history.

Wano Country Arc
Shortly following their meeting with Imu, the Elders granted Cobra the audience he requested at the Empty Throne. Cobra brought up his ancestor, Nefertari Lili who was one of the First Twenty founders of the World Government, and explained how she disappeared following her decision to abdicate living in Mary Geoise; he asked if the Elders had any records of what became of her. The Elders claimed to have no answer for this, and Cobra then asked about the meaning of the initial D., revealing to the Elders' shock that a letter from Lili had been passed down through the Nefertari Family. Imu then entered the room and sat on the Empty Throne, and the Elders were shocked at Imu's decision to be revealed to Cobra. Imu talked with Cobra about Lili and the D., and the Elders drew flintlocks as they intended to execute Cobra for seeing Imu. Imu was the first to strike Cobra, but then along with the Elders was attacked by Sabo using Hiken. Following the attack, the Elders and Imu transformed into beastly forms and pursued Sabo as he fled the room with Cobra. Following another strike by Imu, Cobra sacrificed himself to allow Sabo to flee and was promptly killed; the Elders then noticed that Wapol had been spying on the affairs in the room through a small peephole.

Following the Levely's conclusion, the Five Elders discussed the Raid on Onigashima, namely the orders they had given to eliminate Nico Robin and prepare to have the Marines assume control of Wano Country in the aftermath of the battle. The Elders then discussed the potential of the Gomu Gomu no Mi, which was consumed by Monkey D. Luffy, actually being the renamed "Hito Hito no Mi, Model: Nika" and awakening; a course of action they did not wish to occur. Walcury dismissed the existence of the Hito Hito no Mi, Model: Nika as a legend, but Ju Peter countered by asking why the World Government had bothered to change its name if it was, saying the objective was likely to erase the fruit from history. The Five Elders commanded Guernica to interfere in the battle between Luffy and Kaidou to eliminate the former, and Guernica sacrificed himself to allow Kaidou to inflict a deadly blow on Luffy.

The Five Elders' attempt to eliminate Luffy proved a failure, as they later came to learn that the Gomu Gomu no Mi had indeed been awakened and Kaidou and Big Mom had both fallen in battle. Because Wano's borders were not opened as was initially expected, the Elders called off the Marine invasion but maintained the order for Robin to be captured.

Egghead Arc
The Five Elders were in the Room of Authority discussing Sabo and the growing issues with Vegapunk on Egghead when they received a call from Imu, who wished to test out Vegapunk's Mother Flame invention; Nusjuro advised to test it on a forested area rather than in the sea. Imu told them to test it on the Lulusia Kingdom, and Nusjuro and Ju Peter both noted how useful the weapon could be to quell long conflict if they could one day use it freely. Imu also gave them the command to find and seize Nefertari Vivi. Later, the Elders received a call from Marine Headquarters revealing they had traced Sabo to Lulusia, and the Elders took note of this stroke of fortune as the Lulusia Kingdom was completely annihilated by the Mother Flame soon afterward.
