Koza in One Piece

Koza grew up in a village near Alubarna, primarily raised by his father Toto. When he was ten years old, he witnessed his village suffering from a drought. In frustration, he traveled to Alubarna to confront King Nefertari Cobra, believing the king was responsible for their suffering. Toto tried to stop Koza and begged for forgiveness for his son's actions.

Instead of punishing Koza, King Cobra admired his courage and love for his people. He promised to provide relief for the village and even offered to relocate Koza's family to Alubarna. However, Koza accused the king of not understanding their pain and stormed off. During this time, he had a confrontation with Princess Nefertari Vivi.

After moving to a farm on the outskirts of Alubarna, Koza formed a group called the Suna Suna Clan with many local children. Vivi, who had become friends with Koza, joined the group as the deputy leader after a rematch between them. This marked the beginning of Koza's close relationship with Vivi.

Koza and his Suna Suna Clan explored Alubarna and its ruins, even setting up a secret base in the city's clock tower. This was encouraged by King Cobra, who believed that Koza and his friends were positive influences on Vivi's development. Igaram, Chaka, and Pell also looked after the Clan.

However, their adventures took a dangerous turn when a bandit named Agotogi attempted to kidnap Vivi. Koza immediately ordered his friends to protect her with their lives. Despite their bravery, they were overpowered by the bandits. Koza managed to follow them and fought Agotogi, sustaining an injury over his left eye.

His efforts gave Cobra, Chaka, Pell, and Igaram enough time to arrive and defeat the bandits. Koza and the other children received medical care from Cobra's physicians, but Vivi was deeply moved by their willingness to risk their lives for her. This incident made Koza even more determined to fight for his beliefs and his loved ones, and he even asked Chaka for combat lessons.

After the Agotogi incident, Koza's father, Toto, accepted a proposal from King Cobra to turn the Yuba oasis into a proper town. Koza was excited about this idea and joined the effort, along with many other families. This marked the unofficial end of the Suna Suna Clan. However, Koza promised to stay in touch with Vivi and encouraged her to become a great princess.

Yuba initially showed promise as a new town, but it soon faced problems due to the actions of Sir Crocodile. Crocodile's organization, Baroque Works, smuggled Dance Powder into Alubarna and caused a drought in Arabasta. This, along with other acts of sabotage, led to armed rebellions in various villages and towns, including Yuba.

While Toto remained loyal to the king, Koza grew cynical and returned to Alubarna. He asked King Cobra to use Dance Powder to alleviate the drought, but Cobra refused, wanting to wait for natural rain. Koza accused the king of not understanding the suffering of his people and joined the rebellion.

As the drought continued, Koza became the leader of a rebel army consisting of hundreds of thousands of people. Unaware of Crocodile's involvement and the fact that Vivi and Igaram had left to investigate, Koza led the rebels in numerous clashes against Cobra's forces.

Despite his father's disapproval, Koza and his allies made Yuba their main base of operations. When the drought, worsened by Crocodile's sandstorms, made Yuba uninhabitable, they moved to the oasis-town of Katorea.

Arabasta Arc

On the day Vivi returned to Arabasta with the Straw Hat Pirates as allies and knowledge of Crocodile's plans, Koza believed that the rebellion had reached a critical point. He decided to launch a full-scale assault on Alubarna. However, he consistently refused to allow children to join the fight, even harshly rejecting a young shoeshine boy named Kappa.

At the same time, Baroque Works initiated Operation Utopia, during which they abducted King Cobra and had Mr. 2 Bon Clay impersonate him. The impostor king confessed to causing the drought and ordered the destruction of Nanohana. Despite his cynicism, Koza was deeply disturbed by these events. He traveled to Nanohana to seek an explanation, but the fake Cobra had him shot.

Koza survived the gunshot wound, losing whatever faith he had left in the king. As he moved through the burning Nanohana, he discovered some of his lieutenants caring for a severely wounded Kappa. Believing Kappa's injuries were due to the king's actions, Koza resolved to capture Alubarna as quickly as possible.

Koza's army grew to nearly two million, with additional weapons from a Baroque Works freighter after the Nanohana attack. Vivi and her allies attempted to intercept and reason with Koza's forces at Alubarna's main gate. Anticipating this, Crocodile had Baroque Works agents try to stop them. While the elite agents were occupied by the Straw Hats, a Royal Army infiltrator fired a cannon prematurely, allowing Koza and his troops to pass by Vivi without encountering her.

As the rebel forces advanced on Alubarna, Koza rushed to the royal palace, hoping to convince Cobra to surrender. However, when he reached the palace, he discovered Cobra impaled by Crocodile and Miss All-Sunday in the palace gardens. Most of the palace guards, including Chaka, had been defeated, and Vivi was the only one left standing to defy Crocodile and Miss All-Sunday.

Crocodile revealed his manipulations to Koza, explaining that Cobra was innocent. Chaka, despite his injuries, warned Koza that Crocodile intended to unleash a massive bomb on the city square. Chaka held off Crocodile, allowing Vivi and Koza to arrange a mutual surrender between their respective factions.

Following Vivi's orders, dozens of royal soldiers joined Koza outside the palace, waving white flags and declaring their desire for peace to the approaching rebel forces. However, several Baroque Works infiltrators among the soldiers shot Koza from behind, reigniting the rebels' suspicions. The situation became even more chaotic due to one of Crocodile's sandstorms. Despite Koza's desperate pleas for peace, the fighting resumed with increased intensity.

Only when Monkey D. Luffy personally defeated Crocodile, coinciding with a sudden rainstorm, did the conflict finally come to an end. Shortly after this, Koza was reunited with Vivi. Despite his injuries, he remained optimistic about recovery and pledged to help his father rebuild Yuba.

Upon returning to Yuba, Koza recovered relatively quickly and was able to hear Vivi's coming-of-age speech.

Gedatsu's Accidental Blue Sea Life

Koza was later seen at Ukkari Hot-Spring Island, which is owned by his uncle Goro. He spent time there with Gedatsu, a former high priest.

From the Decks of the World

By the time of the Straw Hats' reunion on Sabaody, Koza had become Arabasta's Environmental Minister. He smiled while reading about the Straw Hat Pirates in the newspaper.

Zou Arc

When Vivi and her father left Arabasta for the Levely, Koza was there to see them off.

One Piece: Stampede (Non-Canon)

He attended the Pirates Festival with others.

Koza's key traits are his deep love for his country, family, and friends. This love drives him to take significant risks to protect what he holds dear. Even as a child, he was willing to risk his life to safeguard his friends in the Suna Suna Clan. As an adult, he leads an entire army to defend his homeland. King Cobra noticed Koza's unwavering devotion to the country from a young age, and despite the years that passed, Koza's commitment remained unchanged.

He is a natural leader and has held leadership roles both as the captain of the Suna Suna Clan in his youth and later as the head of the Rebel Army. Koza's influence is apparent, as he managed to gather a massive army of 2 million warriors to challenge the Royal Palace. After the timeskip, he continues to hold a prominent position as the Environmental Minister of Arabasta.

Koza is a courageous individual who consistently strives to protect his friends, village, and country whenever he believes they are in danger. His readiness to confront a bandit threatening Vivi as a child is a clear example of his bravery. His friends and followers trust and admire him for his unwavering dedication.

He has a short temper and is unafraid to defy rules that conflict with his sense of justice. This willingness to stand up for what he believes in led him to rebel against the king, even when his father advised against it. Nevertheless, Koza's motivations are always pure, driven by his desire for the prosperity of his country and the well-being of his friends.

His actions, such as his efforts to halt the war between the royal army and the rebels after uncovering the truth about the Baroque Works conspiracy, reflect this commitment to justice and the welfare of his homeland.

Koza typically dons purple-tinted glasses and bears a scar on his left eye, a memento from a childhood brawl with Agotogi. During the Battle of Arabasta, Koza sported a dark purple jacket extending down to his ankles, complemented by a white shirt adorned with an ornament hanging from his neck. His attire also included black pants and a yellow sash around his waist.

After a two-year interval, Koza reemerged in Yuba, showcasing a more robust physique. His ensemble consisted of a short-sleeve shirt paired with black pants. Notably, he retained his distinctive purple-tinted glasses and desert goggles, worn around his shirt collar. He additionally carried a pistol attached to his belt and wore gloves on his hands.

Koza has remarkable courage and leadership skills. As a child, he demonstrated these qualities and later as an adult, he led a massive army against the reigning monarch of Arabasta. He could also bring that same army under control with a single command, showcasing his strong leadership.

In terms of physical abilities, Koza's strength and speed do not appear to exceed the capabilities of an average human. However, he exhibits exceptional endurance and stamina. Despite being shot multiple times in the torso, he not only survived but was also able to continue speaking and fighting less than a day after the ordeal, underlining his resilience.

As a youth, like others from the Suna Suna Clan, Koza used a crude wooden club as a weapon. Despite his small size, he could wield it effectively enough to knock out a grown man. Later, as the leader of the rebel army, he utilized several firearms and a sword. His swordsmanship, which he learned through childhood training from Chaka, was competent, even if it was not particularly exceptional. In his role as the Environment Minister, Koza still carries a pistol, emphasizing his familiarity with firearms.

Nefertari Cobra

Initially, Koza had a confrontational relationship with King Cobra. He believed the king was responsible for the suffering caused by the drought in his village. However, after his confrontation with the king, it was evident that Koza's anger and frustration stemmed from a deep concern for his people.

King Cobra admired Koza's courage and offered to help his village, even suggesting they move to Alubarna. This gesture indicated that King Cobra respected Koza's love for his people, even though Koza accused him of not understanding their pain.

Nefertari Vivi

Koza had a complex relationship with Vivi. Initially, he confronted her in frustration and later formed a close friendship with her after she joined the Suna Suna Clan, becoming the deputy leader. This close association with Vivi continued throughout their adventures and struggles.

Koza cared deeply for Vivi and was determined to protect her at all costs. Their bond strengthened during the rebellion, and Koza's actions demonstrated his commitment to both his beliefs and his loved ones.

Suna Suna Clan

Koza formed the Suna Suna Clan with local children, and they became like a family to him. His friends within the clan, including Vivi, shared in his adventures and endeavors to protect their homeland. The clan's existence was encouraged by King Cobra and others who believed they were positive influences on Vivi's development.

Toto (Father)

Koza and his father Toto had fundamental differences in their approach to solving the problems caused by the drought. While Toto remained loyal to the king, Koza grew cynical and joined the rebellion. Toto tried to stop Koza's actions, but their differences created tension between them.

Baroque Works and Crocodile

Koza believed that the actions of the Baroque Works organization, led by Sir Crocodile, were causing the suffering of the people in Arabasta, which fueled his determination to lead the rebellion against the organization. Koza was initially unaware of the true extent of Crocodile's manipulations, leading to tragic consequences for his forces.

Straw Hat Pirates

While Koza didn't have direct interactions with the Straw Hat Pirates, he indirectly benefited from their actions when they supported Vivi in her efforts to thwart Crocodile's plans and bring peace to Arabasta.

In addition to the One Piece manga and its anime adaptation, Koza also appears in One Piece video games.

He appeared in One Piece: Going Baseball and One Piece: Gear Spirit as a playable character and a supporting character respectively.

He also appeared in the following games as a non-playable character:

• Grand Battle! 2

• One Piece: Grand Battle! Rush!

• One Piece: Dragon Dream!

• One Piece: Pirates Carnival

• Despite his significant role in the events of the Arabasta Arc, Koza never met any of the Straw Hat Pirates, except for a brief encounter with future member Nico Robin.

• Koza's birthday falls on May 26, and it is derived from his name, as 5-26 can be seen as Ko-za.

• His favorite foods include fully grilled yakitori and Yuba water.
