Yonbi: Son Gokū, the Four-Tailed Giant Monkey-Tailed Beast in Naruto
Yonbi, also known as Son Gokū, is one of the nine legendary tailed beasts in the Naruto series. A gigantic monkey-like creature with four tails, Son Gokū is one of the most distinctive and powerful beings in the world created by Masashi Kishimoto. His character combines immense physical strength, powerful chakra, pride, intelligence, and a complicated history with humans and jinchūriki.
The word Yonbi means “Four-Tails,” identifying Son Gokū by the number of tails he possesses. Like the other tailed beasts, he was created from the chakra of the Ten-Tails and became an important part of the history and conflicts surrounding the shinobi world.
Who Is Son Gokū?
Son Gokū is the Four-Tails, or Yonbi, and takes the form of an enormous red-furred ape or monkey with four powerful tails. His physical appearance immediately distinguishes him from the other tailed beasts.
Unlike an ordinary animal, Son Gokū possesses enormous intelligence and can communicate with humans. He has his own personality, opinions, emotions, and sense of pride.
Son Gokū is particularly proud of his identity. He dislikes being treated simply as a weapon or as a source of chakra. This attitude is shared by many of the tailed beasts, who have suffered from human attempts to control their immense power.
The Origin of the Tailed Beasts
To understand Yonbi, it is important to understand the origin of the tailed beasts.
According to the mythology of Naruto, the Ten-Tails was an extraordinarily powerful creature associated with the Divine Tree. The Sage of Six Paths, Hagoromo Ōtsutsuki, ultimately separated the Ten-Tails’ chakra into nine individual beings.
These beings became the nine tailed beasts.
Son Gokū was one of those nine creations. The tailed beasts therefore share a common origin but developed their own identities and personalities.
This history also explains why the tailed beasts are much more than conventional monsters. They are living beings possessing enormous amounts of chakra.
Son Gokū and His Personality
Son Gokū is proud, aggressive, and sometimes difficult to approach, but he is not simply an evil creature.
His pride comes partly from the way humans have treated the tailed beasts throughout history. Humans often attempted to capture, control, or exploit them because of their enormous chakra.
Son Gokū therefore has reasons to distrust humans.
He is particularly sensitive about being called a mere animal. His relationship with Naruto eventually demonstrates that the tailed beasts can form genuine bonds with humans when they are treated with respect.
Son Gokū’s personality also reflects his independence. He does not easily submit to others, and his cooperation has to be earned.
The Jinchūriki of the Four-Tails
One of the most important human characters associated with Son Gokū is Rōshi, a shinobi from Iwagakure, the Hidden Stone Village.
Rōshi became the jinchūriki of the Four-Tails.
A jinchūriki is a human who has a tailed beast sealed inside their body. The process gives the human access to extraordinary power, but it can also create enormous physical and emotional difficulties.
Rōshi spent many years learning to control the Four-Tails’ power. His relationship with Son Gokū was complicated, but unlike some other jinchūriki relationships, there was a degree of understanding between them.
Rōshi’s experiences demonstrate one of the central themes of Naruto: the difficult relationship between humans and the tailed beasts.
Son Gokū’s Monkey-Like Appearance
Son Gokū’s appearance is significant because he resembles a gigantic monkey or ape.
The character’s name also evokes the famous figure Sun Wukong, the Monkey King from the Chinese literary classic Journey to the West. Sun Wukong is a legendary monkey associated with extraordinary strength, magical abilities, rebellion, and adventure.
However, Son Gokū in Naruto is his own fictional character within Kishimoto’s universe. His design and personality are adapted to the mythology and storytelling framework of Naruto.
The connection creates an interesting layer for fans familiar with East Asian mythology and literature.
Son Gokū’s Abilities
As a tailed beast, Son Gokū possesses enormous chakra reserves and tremendous physical strength.
His size alone gives him an enormous advantage in combat. He can overpower ordinary shinobi through sheer physical force.
One of his most important abilities is the use of lava-based chakra techniques.
Son Gokū possesses the ability to manipulate Lava Release, a powerful nature transformation associated with fire and earth-based chakra.
His lava techniques can produce extremely destructive attacks. This ability makes the Four-Tails particularly dangerous in large-scale battles.
He can also use the characteristic tailed-beast technique known as the Tailed Beast Ball, an extremely concentrated sphere of chakra capable of causing massive destruction.
Tailed Beast Ball
The Tailed Beast Ball is one of the signature abilities associated with the tailed beasts.
It is created by combining positive and negative chakra in a particular ratio and compressing the resulting energy into a highly concentrated sphere.
When released, the attack can cause enormous destruction.
For Son Gokū, this ability is especially significant because of his immense chakra reserves. The attack demonstrates the enormous difference between the power of a tailed beast and that of an ordinary shinobi.
Son Gokū and Naruto
Naruto Uzumaki eventually develops relationships with several tailed beasts, including Son Gokū.
This is an important development because Naruto does not regard the tailed beasts simply as weapons.
Instead, he attempts to understand their suffering and individuality.
Son Gokū initially remains suspicious of humans, but Naruto’s determination gradually changes his perspective.
Their relationship reflects one of the most important messages in the Naruto story: cooperation can replace hatred when individuals are willing to understand each other’s experiences.
Naruto’s ability to connect with Son Gokū also becomes important during the larger conflict involving the Fourth Great Ninja War.
Son Gokū During the Fourth Great Ninja War
During the Fourth Great Ninja War, the tailed beasts become central to the conflict.
The Akatsuki had previously pursued the tailed beasts because their members wanted to collect their immense chakra. The organization eventually contributes to a much larger plan involving the Ten-Tails.
Son Gokū becomes involved in the war after being used through a jinchūriki-controlled form.
Naruto’s encounters with the tailed beasts during the war help reveal their individual personalities and histories.
The conflict is therefore not simply a battle between armies. It also represents a struggle over the freedom and identity of the tailed beasts.
Son Gokū’s Relationship With the Other Tailed Beasts
Son Gokū shares a special connection with the other eight tailed beasts because all nine originated from Hagoromo’s division of the Ten-Tails’ chakra.
They are essentially brothers and sisters in the mythology of the series.
Each possesses a different number of tails, appearance, abilities, and personality.
The One-Tail, Shukaku, resembles a giant tanuki-like creature, while the Eight-Tails, Gyūki, has the appearance of a combination of an ox and an octopus. Kurama, the Nine-Tails, resembles an enormous fox.
Son Gokū’s monkey-like form gives him a particularly memorable visual identity among them.
What Yonbi Represents
Son Gokū represents several themes within Naruto.
First, he represents freedom. The tailed beasts repeatedly resist being controlled by humans.
Second, he represents prejudice and misunderstanding. Humans often fear the tailed beasts because of their destructive power without considering their individual personalities.
Third, Son Gokū represents the possibility of cooperation.
His eventual relationship with Naruto demonstrates that even beings who have experienced generations of hostility can form bonds based on mutual understanding.
Conclusion
Yonbi, Son Gokū, is the Four-Tailed giant monkey-like tailed beast in Naruto. He is one of the nine beings created from the chakra of the Ten-Tails by Hagoromo Ōtsutsuki and possesses enormous physical strength, immense chakra, Lava Release abilities, and the devastating Tailed Beast Ball.
His history with Rōshi, his interactions with Naruto, and his relationship with the other tailed beasts make him much more than a powerful monster. Son Gokū is an individual character with pride, distrust, intelligence, and a desire for recognition.
His monkey-like design also evokes the broader cultural tradition of the Monkey King, while his story remains firmly connected to the mythology and themes of Naruto.
Ultimately, Son Gokū’s importance comes from the way his character contributes to one of Naruto’s recurring ideas: power does not determine a person’s nature, and understanding can transform relationships that were once defined by fear and hostility.
