Wang Ya Se (王亞瑟) is the son of the gangster leader Wang Tu Long, who has control over "Tu Long Bang" (土龍幫) - a powerful organization of gangsters. He is one of the protagonists of KO One.


Rich, powerful, self-centered, and his concerns are his looks. Although he has an insightful personality, often has opinions on certain touchable subjects.

Ya Se's most notable habit is to quote authors like Shakespeare. His favorite quote being "To be or not to be, that is a question".


KO OneEdit

Main article: KO One

Ya Se transferred from Tai Ping High School in the western region to the Ultimate Class after he was kicked out for beating up a supervisor.

The incident that made Ya Se famous is the 'Midnight 12 a.m. Jie Yun (Transport) Incident', in which he beat up the whole clan of Hei Shou Gang all by himself because the leader, Dao Ba Jie Sen, insulted him.

Lei Ke Si's Identity Edit

He is the first person to find out that Lei Ke Si is KO 2, although nobody seems to believe him. He has been framed by Lei Ke Si for an assortment of malicious attacks on fellow classmates, and has left the class at a point in the storyline to prove his innocence. When Lei Ke Si finally reveals his identity, he exonerates his name and returns to school.

Key of Evil Edit

Sometime in March 2006, Ya Se's weapon's power runs amok after the stone that contains the demon inside it runs out of power. He tries to shove away the sword demon by repressing it, but it only endures until he loses control. At first, he only attacks those who anger him, but as its power increases, he begins to attack people randomly. Later, he finds out that Hei Long, the final antagonist, is waiting for Ya Se to become one with his Sword in the Stone so he could use their power to become the king of evil.

He gains control over the sword when a girl named Cai Wu Xiong transfers the magical Bear Pearl into his body to help him suppress the sword demon. But when he finds out that Wu Xiong is aging rapidly by the loss of the pearl, he decides to return it to her, which allows the sword demon to take over his body once again.

Key of SolutionEdit

In the final episode of KO One, Ya Se becomes one with the sword demon in hopes rescue his father, Da Dong's parents and Duan Chang Ren, who were all captured some time by the Martial Arts Syndicate. But at the same time, Da Dong, Xiao Yu and Lei Ke Si find a solution to win the battle, and arrive just in time to join forces with Ya Se to infuse themselves with dark powers.

The battle ends with a powerful explosion generated by Wu Xiong's Bear Pearl and strips all fighters off of their powers, thus preventing Hei Long from fulfilling his plan. However, Ya Se and his friends are also rendered powerless.

The X-Family Edit

Main article: The X-Family

In The X-Family (終極一家), he becomes a secondary character who only appears when Xiu, the leader of Dong Cheng Wei, pays them a visit. Picking where the first series left off, Ya Se has lost his powers since the last battle and is waiting to have them restored. The main reason behind Xiu's help to restore their powers is because he is hoping to use their powers to turn against the darkness that is enveloping the universe, which has already inhabited most worlds.

Though he desires the return of his powers, he admits that being powerless has its good sides.

K.O.3an Guo Edit

Main article: K.O.3an Guo

He takes Liu Bei back to his world for medical treatment while Xiu takes his identity until he recovers from his injuries.

Powers Edit

Like many characters, he displays abilities of super-speeding and telepathic communication. He can also shoot offensive energy from both his weapon and his hands to attack his enemies.

He on one occasion produced a force field to protect his gang from harm. (Episode 3)

His other special ability is his super-speed (a regular ability that most people are capable of), which he confirms as well-known, probably means that he can run faster than most people.

Weapon Edit

Sword in the Stone (石中劍)Edit

Shi Zhong Jian

Sword in the Stone

In KO One, Ya Se mainly utilizes a small sword called the Sword in the Stone (石中劍) - a spiritual dagger created by the wizard Merlin and used by King Arthur (only in legends). When he removes the stone from the dagger, the sword demon will possess Ya Se, allowing him to instantly gain evil powers at the expense of losing control over his own actions.

The sword runs amok after the stone that contains the demon inside it runs out of power. As the sword demon inhabits his body slowly, he begins to attack people randomly.

During the final battle, Ya Se becomes one with the sword demon just as Da Dong, Xiao Yu and Lei Ke Si arrive to infuse themselves with dark powers. In the midst of the battle between Hei Long's army and the KO fighters, Cai Wu Xiong releases the power of the Bear Pearl inside her which generates a powerful explosion that strips away all dark energy and the sword demon is finally vanquished.

In K.O.3an Guo, Ya Se manifests energy through his hand instead of drawing out his sword. This indicates the sword is definitely gone after its power core was removed.

Alternate Counterpart Edit


Lan Ling Wang

Lan Ling Wang (蘭陵王)Edit
