Suiryu

Suiryu (スイリュー, Suiryū) is a Martial Artist and user of the Void Fist. He is said to be a top contender in the Super Fight tournament.

Appearance
Suiryu is a young man with tan skin and brown hair kept in a low ponytail. He wears a traditional uniform used in Chinese martial arts, with a black and white top sporting long sleeves and has star shaped decor in front.

After Saitama blows up his clothes from the pressure his punch, he is shown to have a very muscular body underneath his clothes. Furthermore, he is also shown to have wear two armbands in both of his arms.

Personality
Suiryu is an easygoing individual usually seen smiling, but is very eager to fight tough opponents.

Suiryu is otherwise easygoing, addressing Max reason for fighting in a casual manner and claims that his reason for fighting was to live an easy life without worry. After defeating Max with one kick, he offhandedly apologizes for being too strong.

He is also perceptive, realizing Bakuzan's blood thirst. He was also quick to realize that most heroes do their job not for justice but only for self-satisfaction, pride and ego. Furthermore, he also believes strongly in the philosophy of natural selection, which the strong will always prevail no matters what, which reveals a cocky demeanor towards others, which might indicate that in a way he indeed feels superior to others.

Due to the power gap between him and some of the other contestants at the Super Fight Tournament, he is described by Sneck as strong to the point where he finds himself bored much like Saitama. As the result, he seeks to fight strong opponents to seek thrills in battle, which is a thing that he finds he and Saitama are in common. Furthermore, he also admire Saitama at the same time since he realizes Saitama only seek thrills not fame or glory.

So far, he has been seen acting different ways depending the situation, while in public he shows his easygoing traits while with his opponents and himself reveals a much more serious and cocky side of him. This leads to question his true motives and intentions. While he converses with Saitama, it is shown he has a more observant side, and he was immediately able to deduce Saitama was too powerful and bored with his power just by looking in his eyes. During their short conversation, it also appears they somewhat hit it off and have some similar traits.

As much he hates the cocky and fame-craving behaviors of pro heroes from the Hero Association, It is shown that Suiryu highly despises the hero lifestyle at the same time since he thinks all their heroic actions, benevolent preaching and their sense of justice are waste of time and boring. The reason behind this mindset is because he feels that no matter how strong or noble a hero, there is no way he or she can solve all crisis or destroy evil completely. As the result, he chooses a carefree and thrill-seeking lifestyle rather than fighting for justice.

History
When Suiryu was still training, he would mostly fight with his master and mess around with girls. He would also occasionally skip a few lessons. Throughout his life, his incredible strength makes his life easy to like but curses him with boredom since he cannot find strong opponents to seek thrills.

Suiryu won four consecutive Super Fight tournaments in the past. Afterwards, he is rumored to have been traveling for the past three years until he noticed the superb performance by the previous tournament's winner, Garou disguised as Wolfman. Since then, Suiryu has wanted to fight with Garou.

Monster Raid Arc
Suiryu is participating in the Super Fight Tournament in C-City at the C-City Super Stadium. This is the fifth time Suiryu has participated in the tournament. After Saitama defeated Zakos, he begins to wonder if Saitama will be his opponent in the final.

The audience is excited as Suiryu enters the stage. When Suiryu finally enters the stage he finds Max and seems disappointed to see him. Max tells Suiryu that Suiryu's strength is minuscule compared to the the Deep Sea King's. Suiryu admits that everyone has their reasons for seeking strength. When the match begins, Max charges at Suiryu. Max shows off his new move, but gets easily outmaneuvered by Suiryu. Suiryu proceeds to kick Max to the edge of the ring, knocking Max out. Everyone, except Saitama and Bakuzan, is impressed by Suiryu's performance. Suiryu apologizes to Max for being too strong. He is impressed when Saitama defeats Bakuzan in one strike, vowing to do the same.

Monster Association Arc
Suiryu and Sneck face off, with Suiryu casually avoiding Sneck's strikes and questioning his reasons for fighting. He taunts Sneck by telling him that he is ineffectual as a hero, and that he sought power with no particular agenda, with his nonchalant attitude enraging Sneck. However, Suiryu knocks him out with a single blow, musing that no matter what happens, the truly strong will always survive.

After defeating Volten, he will face Saitama (who is disguised as Charanko) in the final. During the fight, he uses multiple untouched kicking techniques on Saitama to warm up the battle, which makes Saitama extremely nervous to keep his wig from falling down from the air pressure generated by the kick. At the same time, Suiryu compliments on Saitama's strength and finds that they have the same dilemma in finding strong opponents to fight as well as the fact that Saitama only seeks strong opponents just like him not fame or glory.

As Saitama agrees on Suiryu's word, he starts to warm up with his fist and asks Suiryu to give him the true experience of martial arts since he's starting to get tired of ending his fights with one punch. Consequently, Suiryu begins to get serious and ready to offer Saitama what he really wants.

He begins to pummel Saitama with a power kick, which moves Saitama from a short distance, despite Saitama blocks his kick with his arms. After that, he initiates a barrage of kick forcing Saitama to dodge. Suddenly, he launches a powerful kick that launches Saitama into the sky and jumps in the air launches a rolling kick so strong that pins Saitama deep into the concrete layer of the arena. After that, he proceed to stomp Saitama's head deeper into the ground shocking the commentator and the audience.

However, Saitama gets up unharmed by his attacks. At the same time, Suiryu asks what was Saitama's routine, nearly exposing his hero identity by saying that he fights monsters. After this, Saitama tries to cover himself by saying that he intends to become a hero. At this time, Suiryu begins to express his disdain about hero lifestyle and persuade Saitama's not to become a hero since it is pointless and boring to do heroic justice and save the day instead people with great strength like Saitama should seek thrill like him.

Suiryu's words anger Saitama so much he lets himself exposed from Suiryu's kick that blows his wig off his head exposing Saitama in front of the crowd. Finally exposed, Saitama angrily throws a short range punch while exclaiming that if Suryu's goal is to seek fun, he shouldn't try to make himself stronger than he is currently. However, Saitama manages to restrain his punch, which creating a powerful air pressure that blows up Suiryu's clothes exposing his muscular body and leaves him in the state of deep shock.
