Saitama is a superhero who saves people for fun. Later in the series he has joined The Heroes Association, also known as the Superhero Society.
Once a young man leading a fairly mundane life on the job circuit, a chance meeting with a crab-like mutant threatening a young boy reawakened Saitama's childhood dream of being a superhero. After saving the child from the mutant, Saitama embarked upon a brutal training regime that cost him all of his hair but granted him a superhuman constitution. He has, however, become a victim of his own success as he is now so strong that any opponent he faces is defeated with one punch, which leaves his super heroic pursuits deeply unsatisfying.
Saitama was created by a mangaka who uses the pseudonym "ONE" for his webcomic One-Punch Man in 2009. In 2012, ONE was approached by Yusuke Murata to consider a collaboration between the two, and the One-Punch Man remake was the result.
Saitama is quite a short, plain-looking man in his mid-twenties with no hair. He often appears quite slightly built, but when he is shown with less clothing it is apparently that his body is actually rather well-toned. While working as a hero, he wears an all-yellow body suit with either a white or red cape and red gloves and boots.
Saitama is usually a casual, somewhat lackadaisical and down-to-Earth sort of person. He can however be annoyed by fairly minor things, and seeks to avoid fuss. Although he is sometimes touchy about his hair, he is usually comfortable in his own skin, and seeks no-one's approval, what he looks for from his superhero endeavours is his own satisfaction. Although Saitama doesn't always seem particularly serious about it, he does show concern for others, and won't let someone come to harm if he can easily stop it.
So far, Saitama hasn't had recurring contact with anyone in the series apart from Genos. He has found the young cyborg's keenness and seriousness irritating at times, especially when he first met him, but they seem to have developed a genuine friendship since, and Saitama tends to look out for his self-appointed disciple when he's in trouble.
As Saitama is watching TV, he notices on the TV that the city is under attack by weird explosions. The destruction is done none other by Vaccine Man as he was rampaging throughout the city. When Vaccine Man wonders about Saitama’s identity, Saitama replies that he’s an average hero. Vaccine Man explains that he was created due to human pollution, and he will wipe out humanity for their crimes but Saitama easily defeats him with one punch.
As Saitama is depressed as he doesn't any kind of emotion be it anger or joy or even excitement since because every time he face a monster he wins by just one punch, it's like their insects in his eyes, at that moment he tried to smack a mosquito but evaded him so he tried multiple times but couldn't hit it and got enraged in the act. In that time Mosquito Girl was fighting Genos, as they fought Mosquito girl was able to summon every mosquito whiten a radius of 50 Km to infuse the blood they sucked into her making hr more powerful. as she attacked Genos , she was suddenly slapped by Saitama sending to her through a building and into the sky.

Sonic who was nervous from his defeat challenged him for another duel after he trained which Saitama accepted. As Saitama returned to his home explaining his story to Genos, he noticed that nobody have realized his deeds, due to him not registering to the national super hero registry. Saitama then decided that he and Genos would take the exam.

As Genos was called to the hero association he discovered From the super hero Bang that a meteor is descending to their city and that their the only S class heroes available. They where tasked to destroy the meteor. As the citizens got evacuated Genos went to face the meteor as he equipped he's arms with he's new weapons but got interrupted by the appearance of the S rank superhero Bofoy.

As the citizens who witnessed the act they were doubting the hero's association efficiency, Saitama acted as if he's the one to take the credits from the other super heroes to tried to help.
As Saitama and Genos were visiting the super hero Fang, they got suddenly an emergency call from the hero association to assemble , including every S ranked hero. As they gathered, they discovered that Lady Shibabawa who predict any of their disasters died, but before died she predicted that a disaster is upon earth within the next half year. After awhile they got attacked by a massive space ship that destroyed the city but the hero association was still intact. The heroes went outside to face the invaders as they confronted one of them, called Melzalgald. As the heroes were fighting, Saitama infiltrated the space ship killing anyone who opposed him. By this time Saitama finally faced their leader, Lord Boros. Saitama was surprised when Lord Boros survived his punch. As the fight escalated Saitama was sent to the Moon by Boros. Saitama has easily returned to Earth by a single jump which resulted in the downfall of the spaceship. He then used his Serious Series Punch technique to defeat Lord Boros.

When King ran away from G4, Saitama followed him. Saitama climbs to 22nd floor, and enters into King's apartment trough the window which was left open. King then recognizes Saitama as the B-class from the S-class meeting. Saitama and King then play a video game, when a giant bird, disaster level demon crashes into King's building. Saitama stops it with one hand. Saitama then asks is it true that all the rumors about him were a lie. King then realizes that it was Saitama who defeated all those monsters that he was given credit for. Saitama asks King if he is going to keep on telling lies. King then says that he doesn't have the guts to decide. Saitama responds by saying that he will not have to decide if he really becomes strong. Then he says that he might come from time to time to play video games with him and then he leaves.
Saitama has phenomenal physical prowess, particularly his strength. He destroyed walls, smashed superhuman beings into pieces and even destroyed a gigantic meteor, all with a single punch in each case. This strength also allows him to make superhuman leaps. He is likewise too durable to be harmed by virtually any form of physical attack displayed so far, and was fast enough to keep up with and out-maneuver the ninja Speed-of-Sound Sonic, a ninja famed for his speed, and also outclass Genos sensors. He also seems to have high amount of endurance as he was thrown to the ground and stomped by a giant and didn't have any expression of pain.
