Kozuki Momonosuke

Kozuki Momonosuke is an inhabitant of Wano Country and the son of the late daimyo of the Kuri region and patriarch of the Kozuki Family, Kozuki Oden. He was born 28 years before the present day, but traveled 20 years forward in time when he was 8 years old. He was first mentioned when Kin'emon told Sanji that he came to Punk Hazard to rescue his "son". His given name was revealed when the samurai was asking if the captive children in the Biscuits Room had seen him, and his clan name was revealed when Kin'emon spoke of his true heritage.

In his first appearance, Momonosuke was seen in his full animal form, an Eastern dragon with a long, pink, slender body. This form has yellow eyes, horns, and scales along his back. In his human form, his appearance matches the stereotype of all samurai found in ancient Japan, with a topknot and the top of his head shaven. As a child, Momonosuke is quite short. Kin'emon used his Devil Fruit ability to give him a pink kimono with peach designs on it, matching his name ("momo" means "peach" in Japanese.) He also wears a red scarf, a purple obi, and a pair of geta.

Momonosuke has a prideful and stubborn personality, as he was unwilling to communicate with the other kidnapped children due to his status as a samurai. He also refused to eat any of the food or candy they offered him. Ironically, this attitude is what prevented him from getting poisoned by NHC10. Despite his pride, he also cried when he thought Kin'emon had died. He claims that he is the man who will become the Shogun of Wano Country. He also claims that he is not afraid of anything and even threw a fit when Luffy asked him if he is afraid of heights. However, he is terrified of Doflamingo after having witnessed his cruelty. Despite his pride and stubbornness, Momonosuke did not deny his fear of him.

Momonosuke loves his parents dearly and bears immense hatred and resentment towards Kaido for murdering them. Momonosuke was also utterly frustrated at his powerlessness for not being able to avenge his parents or protecting his retainers. His immaturity and emotional outbursts initially prevented him from assuming authority, but after being spurred on by Luffy, Momonosuke has begun learning to take charge and fulfill his role as the Kozuki Family's leader. Momonosuke is also very sharp for his age as despite desiring to reunite with his sister, he understands the danger of Orochi learning of her whereabouts and thus opted to search for Hiyori after Orochi's defeat.

Momonosuke's Perverted Side

Despite his age, he seems quite interested in older women like Robin and Nami, and has used a combination of fake innocence and flattery to get the women to treat him maternally, allowing him to get away with things for which grown men would be considered perverted. While it initially appears he really is just innocent, the look that he gives Kin'emon, Brook, and Sanji makes it clear that he knows what he is doing, clearly showing an extremely perverted nature on his part.

As the heir of the Kozuki Family, Momonosuke has authority over its six retainers. Due to this, he is one of the main leaders of the Ninja-Pirate-Mink-Samurai Alliance, which would not have formed without him requesting Luffy and Law's assistance as their equal. As two of his retainers are the mink rulers Inuarashi and Nekomamushi, Momonosuke also has sway over the Mink Tribe, a race of powerful warriors who are very loyal to his clan to the point that they would die for any member or retainer.

He has the ability to communicate with the giant elephant Zunisha, being capable of seeing through its eyes and giving it orders, which is the only way it can do anything but walk. Should Momonosuke order it to attack, he is in command of a powerful weapon capable of wiping out fleets in a single blow. Like his father, Momonosuke also has the ability to hear the "Voice of All Things".

Momonosuke ate Vegapunk's man-made 

Mythical Zoan-type Devil Fruit that was considered a failure. It transformed him into a serpentine dragon which allows him to seemingly fly, when in actuality he somehow produced clouds that he was able to grab onto and climbed up that way.

However, as he has only eaten this fruit recently, he does not seem to have much control over it yet, and in fact transformed unwillingly into his full animal form shortly after consuming the fruit. He did not know that he could produce and climb clouds, as he told Luffy he was stuck in the garbage dump when they met there. When he was frightened by a hunger-induced hallucination, he unconsciously used his cloud ability to escape with Luffy clinging to him.

He also did not know he could switch forms until Luffy told him. It is also possible, though, that he has no conscious control over his power because the fruit was artificial and a failure. He showed the ability to revert back to his human form when he reunited with Kin'emon. However, Momonosuke is shown to switch forms from time to time.

Momonosuke was born 28 years before the present day. According to him, he met the pirate Gol D. Roger at some point. At the age of eight, his family was removed from power by the shogun of Wano Kurozumi Orochi as well as Kaido of the Yonko. After Oden was executed in the Flower Capital, Momonosuke was with his sister and mother inside Oden Castle when it was set ablazed by Kaido. When the retainers returned, Toki sent Momonosuke and the retainers 20 years into the future. After arriving in the future, they went around Wano Country and discovered how much it changed over the years. However, they discovered allies they could still count on and began forming a plan to take back Wano Country. Momonosuke and his retainers also decided to travel to Zou to enlist the aid of the Mink Tribe, but when they left Wano Country, they were spotted by the Beasts Pirates.

While sailing to Zou, but ended up shipwrecked, in which they got separated from Raizo and drifted ashore to Dressrosa. While in the country, Momonosuke witnessed Doflamingo's brutality as he tortured a gladiator for putting an unsatisfying show at the colosseum. The samurai were later pursued by Doflamingo's men. Momonosuke hid himself in a ship and the ship set sail before Kin'emon could reach him.

Momonosuke was taken to Punk Hazard where he was placed in the Biscuits Room with the rest of the children. Despite the other children's kindness to him by offering him food and candy, he refused to take "another's charity" and told no one his name.

Sometime after sneaking out of the Biscuits Room, he wandered into a "secret room," which in reality was Vegapunk's former office. There, he saw the scientist's man-made Devil Fruit inside of a glass display case. Due to his hunger, he smashed open the case and ate the fruit. Soon after, a little girl found him inside the room and talked to him upon entering. Momonosuke told her that he needed to escape and that he had something he needed to accomplish. He listened to her as she talked until they heard the guards coming. She ran away to hide after telling Momonosuke to do the same.

By the time the guards got there, Momonosuke underwent an unconscious transformation into his dragon form. After escaping the guards, he saw his reflection and, upon realizing that he was the dragon, screamed in shock and continued to run away. Running past Caesar Clown's office, Momonosuke overheard the deranged scientist talking about the newest batch of children and how they were only good for about five years of experiments, after which they would die. He was going to warn the other children, but he thought to wait in the garbage dump where he ended up becoming trapped.

Eventually, Momonosuke left Zou for Wano Country and managed to successfully reunite with his retainers. While at Wano, he practiced his swordsmanship with a wooden sword. Sometime later, he reunited with Luffy's group after Law brought them to the ruins of Oden Castle.

Inside the castle, Momonosuke listened as Kin'emon explained more about the story of Oden, how Momonosuke's group traveled to the future, and what they did right after arriving at present time. After Kin'emon explained about the Fire Festival, gave Luffy's group new clothes and tasks to do, and summoned Shinobu, Law alerted everyone in the castle to Kaido's sudden arrival at Kuri. The group was surprised to see Kaido and Momonosuke was terrified. After Luffy rushed off with Law following him and Kin'emon and Kiku left to rescue Tsuru, the rest tried to escape as Kaido approached the castle and destroyed it with a fire breath. Momonosuke and the other males in the group were saved by the kunoichi Shinobu's jutsu which sunk them into the ground.

At Mt. Mt. Atama, Momonosuke witnessed Shutenmaru and Inuarashi's clash as well as Kin'emon's declaration to make Shutenmaru an ally. While Momonosuke was practicing swordsmanship in Amigasa Village, Tama asked him about his sister. Momonosuke believed that his sister is still alive but could not reunite with her until the shogun and Kaido's defeat.

Momonosuke, Tama, Chopper, and Kiku then went to Kuri Beach, where they encountered an amnesiac Big Mom. Momonosuke was shocked to learn from Chopper on who she was and worried about what might happen if she regain her memories. On the following morning, Momonosuke's group took Big Mom to Okobore Town. After Tsuru fed her, the group planned to take her to Udon.

The group then traveled to Udon, with Big Mom having tamed a Wanizame to carry them there. While practicing swordsmanship on the way there, Momonosuke used a certain shout that he learned from Zoro. Kiku was alarmed and she advised him not to use it. After night fell, the group eventually arrived at Udon.

On the next day, Momonosuke's group arrived at the Prisoner Mines after Big Mom broke through the front gate. Kiku told Momonosuke and Tama to hide before proceeding with Chopper. When the emergency gates were closing, Momonosuke and Tama entered the Prisoner Mines.
