Title: “Winch Green.” He is one of Germa 66’s main fighters and uses that name as his military identity. Germa 66 is publicly presented through propaganda as a force of heroes, although in reality it functions as the mercenary army of the Kingdom of Germa.

Yonji is Judge's youngest son and one of the four genetically modified children of the Vinsmoke family. His identity is deeply intertwined with Germa 66 and his status as a prince.

Yonji is a very tall man, standing at 194 cm, with an extremely muscular and well-developed physique due to his genetic modifications. He has a robust appearance, broad shoulders, and great physical strength even without using his combat gear.

He has green hair, styled back with a raised tuft, and the characteristic curly eyebrows of the Vinsmoke family. His facial features closely resemble Sanji's. He has no beard.

He typically wears sunglasses and elegant clothing when off the battlefield, due to his position as a prince. His military attire consists of the Germa 66 Raid Suit, which is green and bears the number "4," signifying his status as the fourth son. He also wears a cape and specialized equipment designed by Germa.

His body possesses an extremely resilient exoskeleton. His skin and body structure can withstand blows that would be extremely damaging to a normal person. Even when he suffers significant physical damage, Yonji can recover with abnormal resilience and pain tolerance.

One particularly striking feature of Yonji is his modified arm, related to his "Winch Green" identity. He can extend it and use it to grab objects or people from a distance, making it one of his main combat abilities.

Yonji is proud, arrogant, competitive, and quite provocative. He has a princely attitude, believing that strength and superiority are important. He likes to demonstrate his abilities and can become easily annoyed when someone hurts his pride.

He is direct and blunt in his speech. He may enjoy provoking conflicts or watching others clash. He doesn't usually show much compassion, and due to Germa's upbringing and genetic modifications, he was originally raised to view empathy and compassion as weaknesses.

He's a womanizer and attracted to beautiful women, though his behavior is far less kind and chivalrous than Sanji's. He can overreact to an attractive woman, but he doesn't share his brother's romantic ideal of chivalry.

Despite his cruel and arrogant personality, Yonji is not entirely incapable of feeling emotions. He can experience pride, shame, anger, frustration, amusement, and nervousness. When someone exceeds his expectations or places him in an unexpected situation, he may become bewildered or react rather clumsily.

He has a complicated relationship with his brothers. He respects Ichiji and Niji's strength and tends to follow the competitive dynamic of the three older brothers who grew up under Judge's influence. His relationship with Sanji is especially strained due to how Sanji was treated during his childhood.

He can be less dominant with Reiju, since she is his older sister and usually has a more mature attitude than him.

Yonji also has a childlike side: he can be impulsive, competitive, teasing, and easily provoked. Although he tries to project an image of a powerful prince, he can become flustered when he loses control of a situation.

Even before birth, Yonji was subjected to scientific experiments by his father, Vinsmoke Judge. Judge genetically modified his children to turn them into enhanced human soldiers.

The modifications caused his strength, speed, stamina, and physical capabilities to develop to superhuman levels from a very young age. Even as a child, his body already possessed physical capabilities comparable to those of an adult.

Its main physical modification is the exoskeleton, an extremely resistant internal structure that strengthens its body and provides it with enormous resistance to impacts and physical damage.

It also has:

Superhuman strength.

Great speed and agility.

Reflexes superior to normal humans.

Exceptional physical endurance.

High pain tolerance.

Great recovery capacity.

Shock and cut resistant exoskeleton.

Modified arms capable of extending through their body technology.

Ability to use Germa 66's advanced technological equipment.

The modifications also affected his emotional development. Judge intended to eliminate from his sons the characteristics he considered useless for soldiers, especially compassion and empathy. Yonji grew up believing that sensitivity was a weakness and that strength was what defined a person's worth.

However, the modifications don't turn Yonji into an emotionless machine. He can feel pride, anger, amusement, shame, frustration, attraction, and other emotions; he was simply raised in an environment where showing compassion was considered unacceptable.

The Kingdom of Germa is a militarized nation in the North Blue ruled by the Vinsmoke family. Unlike other kingdoms, Germa possesses vast scientific and military technology, as well as the ability to travel using its mobile installations.

Vinsmoke Judge is the king of Germa and supreme commander of Germa 66. He is a scientist obsessed with creating superior soldiers and regaining Germa's military power.

Judge's children are part of Germa's elite:

Reiju: the eldest and only daughter of the brothers. She is known as Poison Pink.

Ichiji: older brother, known as Sparking Red. He is serious, proud, and extremely loyal to Judge's ideology.

Niji: second brother, known as Dengeki Blue. He is arrogant, cruel, and possesses abilities related to electricity.

Sanji: third son. He was born with emotions and empathy, which led Judge to consider him a failure during his childhood. Despite this, Sanji developed his own abilities and became a powerful fighter.

Yonji: fourth son and youngest of the male brothers, known as Winch Green.

Yonji holds an important position within Germa 66. As a prince and elite fighter, he has authority over soldiers and is directly involved in military operations.

Germa 66 utilizes advanced technology, genetically modified soldiers, Raid Suits, and scientific weapons. The organization is publicly presented through stories and propaganda as a group of heroes, while its true nature is intertwined with warfare, political power, and mercenary work.

Yonji is proud to belong to Germa and to be a Vinsmoke, although his relationship with his father and brothers is marked by rivalry, family pressure, and Judge's extremely rigid upbringing.
