Saitama

"I'm just a guy who's a hero for fun."

- Saitama

"100 push-ups, 100 sit-ups, 100 squats, and a 10km run EVERY SINGLE DAY!!!"

- Saitama describing the secret behind his power

"You won't survive. You don't get what hero means. There's a lot of incredibly strong bad guys in the world. Those who oppose them are called heroes. Even if they are alone. You, who gathers weaker subordinates to feel strong, won't make it. At this rate, you are gonna cry sooner or later. When a monster stronger than you shows up, none of your subordinates will save you. Factions? Newbie crushing? Keeping your ranks? They have nothing to do with anything! Do not look down on heroes, you moron!"

- Saitama to Fubuki after closing in on her.

Saitama, (a.k.a. Caped Baldy), is the titular protagonist of One Punch-Man, and the most powerful being ever alive in existence. Having apparently trained himself to go beyond superhuman condition, Saitama faces an existential crisis as he is now too powerful to gain any thrill from his heroics.

He is registered with the Heroes Association as a B-Class Superhero (A-Class in the webcomic) and is tasked to defend Z-City against Mysterious Beings.

He is voiced by Makoto Furukawa in Japanese version and Max Mittelman in the English version.

Appearance
Saitama is a slim, bald man of average eyes. He notably wears a yellow jumpsuit, with a black belt, round, gold buckle, white collar, short zip, red gloves, red boots and a cape (red in the manga, white in the anime) that is attached by dark grey buttons.

Saitama is drawn in a simpler style than other characters in the series, having an oval-shaped face, and a simple mouth and eyes. However, when drawn in a more serious style, with more detail, Saitama is revealed to have sharp features and a muscular body.

Saitama initially had messy, black hair and brown eyes, but claims to have lost all of his hair, suddenly, as a result of his intense hero training.

Personality
Saitama is described to be quite indifferent. Even the mightiest foes pose no challenge to him, so he doesn't take his hero work very seriously and defeats monsters as if as he is swatting insects. Since his superhero work has begun to bore him, he is constantly searching for an opponent that can actually provide him with a challenge. The lack of any such opponents has led him to suffer from a self-imposed existential crisis, and he claims that his ability to feel any and all emotions has dulled considerably. He stated that he just became a hero because it was his dream and for self-satisfaction and that before becoming one, he used to suffer from anxiety issues. Despite his boredom, Saitama goes out of his way to stop crime.

"If the Heroes run and hide, who will stay and fight?"

- Saitama to Genos

The combination of his attitude, unstoppable strength, and distinctively simple and "unimpressive" appearance frequently cause his battles to become anticlimactic. Saitama will usually allow his opponents to rant/gloat about their motives and power up into their strongest forms before obliterating them with a single punch. However, if they begin to ramble on too much then he will either interrupt them or just punch them.

A running gag about Saitama is his inability to remember certain people's faces and names, as seen when he forgot Sonic's name and could not remember who Tanktop Tiger was. Because of this, he always ends up pronouncing their names incorrectly.

As of some special chapter during his time participating a costume contest, appearances don't matter to him. The only thing that matters to him are his abilities and his desire to be the superhero he's been training for. That being said, he does care about his own cleanliness, as the only thing he ever really complains about is how he gets dirt on his clothes or blood on his gloves. Though he usually doesn't care about appearances, he has shown dislike towards his assigned hero name, Caped Baldy. Thus, even after receiving it, he always refers to himself as Saitama.

Saitama has been shown to be very humble, as he deliberately let the masses turn against him, for the sake of the defeated heroes to be given credit for their efforts, even claiming that they had weakened the Sea King before his arrival. He did the same for the police in the Special Chapter, dressing as one of them and killed a monster, despite potentially gaining much fame had he revealed who he actually was. He also didn't mind that King took credit for all of his achievements.

Another unusual thing about Saitama is that he is surprisingly tactful and insightful, being well able to discern situations and character traits from the people and environment around him fairly easily. Having picked up a number of hints to Sonic's own persona on their first meeting and when two tank top heroes jealously plotted to ruin him after the meteor event that there were irate and self-serving hero types like them, as well as discerning Fubuki's forced offer of submission or destruction just before his crackdown on how the hero world really works than how it is currently run.

Saitama has been shown to feel empathy for his enemies before, particularly ones who can give him an actual fight and don't go down in one hit. One such example of this being Boros, for whom Saitama sympathized with him due to suffering from similar circumstances. Though in the end, Boros still couldn't draw out Saitama's full power.

Saitama does not actually care if people insult him and he usually ignores them and says that they need a hobby; the only insult that could at the very least get a what could be called reaction out of him is when anyone mentions/makes comments about his bald head. He also shows a measure of concern when it comes to bargains and deals, as seen when he fought Carnage Kabuto, when he was more shocked upon the realization that he was going to miss a bargain sale, rather than his opponent, who had undergone a transformation and was whacking him around. Despite his general indifference to most things, Saitama was genuinely shocked when he realized that no one actually knew of him, despite his achievements (although this could be attributed to the fact that he never stuck around after saving the day).

Saitama shows impressive restraint with his power, considering that he is easily capable of splitting the sky, or jumping from the moon to earth. He manages to beat nearly all of his opponents with a single punch, though occasionally causes more devastation than necessary. While he has no problem killing monsters, Saitama has yet to be seen killing another human, and only ever uses enough strength to knock them out, which still results in them ending up either being severely or critically injured.

Despite his willingness to give the credit to other heroes and not being a hero for fame or glory, Saitama has been shown to enjoy the few moments of fame when he is moved up, such as when he was shocked at the drastic promotion from the lowest C-class to the high C-class. Saitama also expressed jealousy when it turned out that Genos was listed in the top 5 handsomest heroes in the Hero Association and was the 6th most popular hero.

A very fatal flaw of Saitama is that he get extremely furious whenever he loses or is unable to get something done properly. In fact, Saitama nearly killed Bang, one of the top members of the Hero Association, simply because he couldn't control his anger at losing a trivial game. In his dream, he yelled to the Subterannean people that he never loses, further implicating this negative aspect of himself.

Powers and Skills
Hence his moniker, Saitama is the titular character of One-Punch Man and the strongest character in the entire franchise. So far no enemy has been able to injure him in any way and almost no enemy is even able to survive from a single earnest punch from him. The origin of Saitama's immeasurable strength remains mysterious and unclear. Although he tells everyone he got his incredible power through mere physical training, no one believes him at all. According to Saitama, after a year and half of 100 daily push-ups, sit-ups, and squats, plus 10 km daily running, he had achieved some level of superhuman strength. This training was apparently so intense for Saitama that he at times felt he might die, and claims that it is what caused all of his hair to suddenly and eventually fall out. He apparently continued his training for another year and a half before beginning his hero career. Genos believes that Saitama doesn't actually know or understand how he gained his power, and hopes to learn the secret by sparring with and observing him, while Dr. Genus (on the other hand) believes that Saitama worked out with said training regimen so hard that he had removed his natural limiter completely, granting him access to unlimited power. It should be noted, that Saitama would complete all parts of the training one after the other without breaks and was battling mysterious beings that appeared during that time, which would have made completing the training more intense than would normally be expected.


 * Immeasurable Strength: Saitama possesses an apparently limitless strengh and as a result is capable of destroy powerful monsters and villains with a single one punch (though this strenght is not limited to punches). Until now, the exact raw of power of this strenght remains unknown, since Saitama most of the time only uses a small porcent of his power to destroy enemies and weird are those occasions where Saitama needs more try to defeat enemies. It is shown that the level of power of this strenght is so big, that only the shockwave from his punches is enough to completely destroy a mountain and smash buildings and other superficies where he land on, it is shown that Saitama can control his force but still tends to exaggerate and cause a lot of destruction but luckily never killing any innocent in the process. The destruction level of Saitama's strength its been confirmed as multi-planetary at its minimum, so it is mighty possible he has yet a lot to show.
 * Enhanced Leap: Saitama's inability to fly is somewhat compensated by his immense leg strength, allowing him to leap tremendous heights and distances at high speeds. This can be seen when Saitama smashed his head through the ceiling of a gymnasium during the hero tryouts simply by jumping. He was also able to smash a building into its foundation just by leaping off from its roof. His greatest feat in this regard, however, was when he jumped from the surface of the moon and ended up back on Earth at a specified point, leaving a crater on the moon's surface in the process. Murata has stated that if Saitama hadn't striked the moon, he could have jumped from the empty void of the space instead.


 * Immeasurable Speed: Not only he is insanely strong, but he's also a terrifyingly fast. He is shown to effortlesly surpass Sonic in speed, no matter how hard the latter trains to improve his speed Saitama always remains as the fastest. An impressive feast of his speed is left afterimages behind him due to how fast he is ruuning, this allows him to create "speedy-clones", even Genos was fooled by one of them during their sparr and had problems to find him even with his sensors at MAX. After Sonic shows up and challenges him again he use his speed to create about 10 clones of himself, which impress Fubuki who states that's a S-rank technique. Saitama, stoic, uses his "serious mode" to do the same but creating tons of copies of himself, which alone shocks and beats Sonic easily. He's shown able to move any part of his movie but not full body at amazing speeds and easily dodge attacks that travel even fastes than light.
 * Afterimages: Saitama is so fast that he leaves afterimages when moving at high speeds, and is agile enough to dodge Beast King's Lion Slash: Meteor Shower while moving in for the kill.undefinedAfter assaulting Saitama with a flurry of punches in his practice fight, Genos realized that he was only fighting his afterimages.
 * Supernatural Dexterity: Saitama is capable of moving any of his limbs at extremely fast speeds without even flinching, not stopping until his target is completely obliterated. This is seen when Saitama flawlessly whacks all moles on a Whack-A-Mole machine and destroys it during the Hero Association exam.


 * Immeasurable Agility: Saitama is seen able to make high acrobatic and agile maneuvers, possessing great athleticism, being even more agile than Genos.


 * Supernatural Reflexes and Senses: He effortlessly sees attacks beyond light speed and can hear, see, and smell much more than normal humans ever could. Nevertheless, Saitama's senses seems to not have the same degree of "resolution" that some of Genos sensors, still he is able to pick up on chatter from various bystanderts while fighting. He is also able to see in the dark, as he was able to spot a kid a great distance away during the night. His tracking capability is also astonishing, as he can concentrate on a fast-moving object for a long time and still not lose sight of it, as seen when he was the only person to see Garou escaping. He seems to have developed a sixth sense, being able to avoid danger without even noticing it, because of this, he is able to dodge or defend himself against enemies without even realizing he's been attacked.
 * Immense Stamina: Saitama has never been shown to get tired when fighting villains. Even when unleashing a punch more powerful than a planet-destroying attack, Saitama showed no signs of fatigue. The only time in which Saitama was shown to be panting and out of breath, he recovered just seconds later.


 * Absolute Invulnerability: Nothing has ever been close to harm him in any possible way, not even attacks confirmed to be multi-planetary like Boros's final attack are a warn to him. During his training with Genos, when the cyborg almost manages to bure him with one of his attacks, Saitama was more concerned about his costume not getting burned instead of his own safety, which proves he was never in danger to being with. Hilariously, despite his invulnerability he was hurted by a cat he rescued and scared by accident, though he does not exhibits reals signs of pain aftermath.
 * Phychic Immunity: He is shown to be inmune to phychic attacks, even from extremely powerful phychics like Fubuki, Tatsumaki and Geryuganshoop, who created an atmosphere with the gravity of a blackhole to suck and kill him, Saitama didn't even blank.
 * Enhanced Lung Capacity: Although Saitama cannot breathe in space, he has considerable control over his breath. Even in outer space, Saitama manages to hold his breath effortlessly, and he even made a jump back to the Earth to the Moon in seconds without showing any signs of suffocation or symptoms. It also takes some time for Saitama to realize he is in a vacuum environment, although it seemed to have little to no effect on him.
 * Vacuum Adaptation: Saitama's body has been shown to survive the effects of a vacuum unscathed. Several factors like a lack of atmosphere are at play here, although Saitama has been unable to be affected by any of them.
 * Temp Immunity: Saitama is immune to all types of temperature-based attacks. In fact, he is immune to temperature energy in general. When Genos created a huge, spherical blast of flame to kill Mosquito Girl's mosquitoes, Saitama remains standing right next to him totally unharmed and unperturbed (though his clothes were destroyed).undefinedAlso, after Boros, in his fully-powered state, punched Saitama to the Moon, Saitama, unharmed in the process, jumped back to Earth in just seconds, and upon atmospheric re-entry, his clothes started to burn, but he remained unscathed.
 * Pain Supression: Even before becoming powerful, saitama was still able to supress pain during battle.
 * Expert Hand-to-Hand Combatant: Although saitama had never received formal training, he does shows extraordinarily high levels of proficiency and ability as a combatant. Due to his boredom, saitama usually doesn't care about finesse or style and makes use of attacks poor executed and flawed; however, once serious, Saitama becomes an incredible formidable and skilled combatant, swiftly combining his incredible physical abilities in order to overwhelm his opponents. Saitama's attacks and methods are very basic, but solid and efficent thanks to his superhuman prowess, he is able to make strikes with great control and precision and possess vast amount of combat experience, having fought countless criminals, evil organizations and supernatural monsters during the three years of his training. Having excellent battlefield awareness, Saitama is able to easily read, dodge and counter moves and techniques from enemies immeasurable fast and dangerous like Sonic, Genos and Boros, or even highly skilled and experienced combatants like Garou. He uses wrestling and street fighting techniques to grap and takedown his opponents and is an extremely dangerous fighter in close combat, Saitama also has some knowledge of karate, as showed in his fights with garou and sonic, where he knocks both of them with a clean (albeit basic) karate chop.
 * Normal Series: Saitama's Normal Series consists of techniques in which he puts little to no effort into attacking. Even though his attacks are flawed and wasted (Garou even called him an amateur for such poor style), most opponents tend to be finished off easily due to Saitama's extreme strength and speed.
 * Consecutive Normal Punches: Saitama launches a volley of quick, single-handed punches from his right hand. These blows have been shown to be powerful enough to blow strong or large body types apart into pieces. Depending on the power of the attack, this technique can occur in an instant.
 * Two Handed Consecutive Normal Punches: Saitama launches a volley of quick punches from both hands instead of one.
 * Serious Series:  Saitama's Serious Series consists of techniques in which he puts effort into attacking. While he normally punches without putting in much effort, when Saitama gets serious in a fight, his techniques become tremendously powerful.
 * Serious Punch: Saitama throws an extremely powerful punch. The full extent of this attack is unknown, as it never directly hit an opponent. It was so powerful that it completely negates Boros's Collapsing Star Roaring Cannon, a beam capable of wiping out an entire planet.undefinedThe shockwave alone from the punch was powerful enough to part clouds on a global scale, as well as deliver the final fatal blow to Boros. The dying Boros then also declared that Saitama's fatal attack on him was not even anywhere near Saitama's true power, and that Saitama wasn't even trying.
 * Serious Side Hops: Saitama hops from side-to-side rapidly. Doing so allows him to create a multitude of afterimages. He has been shown to be able to walk forward while doing so, and the shock wave caused by it was enough to break Sonic's Ten Shadows Burial.
 * Serious Table Flip:  Saitama digs his fingers into the ground and flips a large amount of landmass thousands of meters into the air. He first used this technique against Garou, to which the effect was so great that Garou's sense of gravity was severely warped as a result.
 * Serious Headbutt: Saitama headbutts his target. He uses this to counter a punch from Garou, destroying the latter's arm.
 * Strategist: While Saitama usually relies on raw power to beat his enemies, he is also shown to be an smart and adept fighter able to use strategy when require it; such when he killed his first monster with skillfully use of his tie despite being just a normal human without powers, and when he managed to make Garou unable to predict his moves through tactic use of his speed, agility and the enviorenment before knocking him off with a punch.
 * Indomitable Will: Saitama has been shown to possess incredible willpower, it is most evident in the flashback to his hero training regime. Even if he was in great pain, or could barely move, or vomited blood, he continued his training; through sheer willpower and effort, he removed his natural limiter.
 * Accelerated Healing Factor: While it's never specificated if Saitama does possesses a healing factor, he is able to restore himself in a surprising short amount of time. Better shown during his training, where despite all the pain and nausea from his constant battles and training routine, he quickly recompose himself and returns to action with apparently no injuries.

Fighting style
Saitama's fighting style mostly consists of basic and improvised fighting techniques, like punches and kicks, these basic moves make full use of his physical prowess and turns into deadly attacks.

Weaknesses
He isn't skilled in martial arts, which comes as a high disvantage when fighting Garou, a prodigious and refined martial artist with high amount of power and the ability to predict any kind of fighting move, no matter how mundane or technical is.

He also can't breathe in space (like normal humans couldn't) although he is seen capable of hold his breathe about an indeterminated time while still being able to fight.
