Saitama decided three years before the start of the story to become a hero for fun after saving a boy with a cleft chin from the monster Kanirante during a failed job‑hunting period.

He trained so hard over those three years that he lost all his hair and broke past his natural limitsbecoming an invincible being whose strength eclipses S‑Class heroes and even god‑level threats.

Despite his peerless mighthe initially works as an unregistered “hobby hero” who receives no recognition until Genos tells him about the Hero Association.

He then joins the Associationbarely passing the written test and starting at the very bottom of C‑Classeven though his physical exam scores break every record.

Saitama has a lean but muscular buildstanding 175 cm tall and weighing 70 kgwith a plaincompletely bald head and simple facial features that are actually fairly handsome when drawn seriously.

Most of the timehe is depicted with a comically simplealmost doodle‑like facebut when he gets serious his expression becomes sharp and “cool,” and the art tightens accordingly.

Casual Clothing

In daily life Saitama wears hoodies and T‑shirts with silly logos like “OPPAI,” paired with sweatpants or simple pants.

He owns more clothes than his slacker look suggestsmeaning he does care a bit about fashionbut his taste is offbeat by normal standards.

Hero Suit

As a heroSaitama wears a yellow full‑body jumpsuit with a front zippera short white capeand red gloves and boots.

This outfit was given to him by a friendly clothing‑store owner back when he still had hair and had just begun his hero activities; before thathe fought monsters in a blue tracksuit.

The yellow suit with red gloves is a deliberate color inversion of a certain famous bread‑headed children’s heroone of several tongue‑in‑cheek references in One‑Punch Man.

His costume is as indestructible as his body in practicesurviving atmospheric re‑entries and apocalyptic battles with barely any damage.

On the surface Saitama is lazydeadpanand socially awkwardoften more interested in garbage collection days and supermarket sales than in the monsters threatening humanity.

He is bad with ordinary social normshas little small‑talk skilland frequently forgets people he has met unless they left a very strong impression.

Howeverhe holds a firm private creed that “a hero is someone who stands up for the peopleeven alone and without any chance of winning.”

He respects and admires heroes whose actions match this idealsuch as Unlicensed Riderand will go out of his way to protect their dignityeven at the cost of his own reputation.

Saitama does not actively chase famebut he does possess some desire for recognition and validation.

He initially joins the Hero Association because being told “no one has ever heard of you” by Onsoku no Sonic makes him realize how unknown he is despite his efforts.

His extreme strength leaves him chronically bored and emotionally numb in battlesince almost every opponent falls to one strike.

This boredom becomes a genuine existential problem: he laments that nothing excites him anymoreand he starts seeking “a worthy fight” as if that would give his life meaning.

When he later confides this to KingKing calls this attitude arrogant: Saitama is looking for “fun fights” instead of focusing on helping peopleand refuses to grow or find other hobbies because he believes he has “nothing left to do” as the strongest.

King suggests that instead of just being the strongestSaitama should aim to become “the greatest hero,” pushing Saitama to at least begin rethinking his heroism.

MorallySaitama can be both noble and petty.

He will deliberately take the blame for collateral damage to preserve other heroes’ honorbut he will also stick Fubuki with the bill when he forgets his wallet or throw a tantrum and break a controller after losing at video games to King.

He is sensitive about his baldnessespecially because the Hero Association named him “Caped Baldy,” which he hates and never introduces himself by.

He always calls himself “Saitama” instead and is quietly hoping for a better hero name someday.

Saitama lives like a lower‑class bachelor and is almost always brokemostly because his rank and popularity lag far behind his actual contribution.

He obsessively hunts supermarket specials and gets genuinely upset when he misses a sale.

He is frugalrarely splurging even after Genos brings in plenty of money when he moves in as a live‑in disciple.

His favorite cheap luxury is a budget conveyor‑belt sushi chain called “Rat Sushi,” where he occasionally eats out with Genos.

Saitama sees three meals a day as part of his training; breakfast can be as minimal as a bananabut he eats regularly.

He is not a huge eater: he fails a “mega‑sized ultra‑spicy udon” challenge that Genosbeing a cyborgfinishes without trouble.

His sense of guilt is surprisingly normal when he accidentally destroys other people’s property while fighting.

He will sometimes attempt to compensate or help out afterwardthough usually in his awkwardlow‑effort way.

For Saitamabeing a hero is fundamentally a “serious hobby” he does because he wants tonot because society expects it.

He insists that even if no one knew his namethat alone wouldn’t make his work meaningless.

His ideal hero is someone who faces overwhelming evilnever gives upand wins by pouring in everything they have right at the last second.

This makes him resent how easily he wins; he often feels cheated when a seemingly promising opponent goes down with one punch.

Despite thisSaitama does not think heroism is just about fighting.

He casually helps people in small ways and will spare monsters that are harmlesspeacefulor have surrenderedlike tamed dogscowed monstersor creatures that simply want to live quietly.

At the same timehe can be disturbingly unconcerned with collateral damage and broader consequences.

His battles indirectly contributed to the destruction of entire city districtsand he occasionally only realizes the financial cost afterward and panics.

During his clash with Terrible Tornadohe becomes much more visibly attentive to nearby property damagetelling her not to “wreck other people’s stuff.”

This hints that his outlook is slowly shiftinginfluenced by King’s lecture and the growing scale of the disasters around him.

Three years before the main storySaitama was a job‑hunting young adult repeatedly rejected by companiesdrifting without purpose.

When he happened to encounter Kanirante attacking a boyhe barely managed to save the child despite being badly beatenand this reignited his childhood dream of becoming a hero.

Determinedhe began a brutal but comically simple training regimen:

– 100 push‑ups every day

– 100 sit‑ups every day

– 100 squats every day

– 10 km running every day

– Do this every single dayno breaksregardless of weather or illness

– Eat three meals a day

– Never use air conditioning or heatingto “train the mind”

He attributes all his strength to this routineand he sincerely recommends it to others seeking power.

Everyone who hears thisincluding monsters and scientistsis baffled and refuses to believe that such mundane training could produce a being like Saitama.

Dr. Genus (Genus‑hakase)the founder of the House of Evolutiontheorizes that Saitama is a normal human whoby repeatedly surviving near‑death battlestore off his own biological limiter and evolved into something beyond.

Even before fully awakening his powerSaitama had above‑average toughnesssurviving multiple hits from tiger‑level Kanirante while only bleeding slightly.

Saitama is the single strongest character in the seriesfar surpassing S‑Class heroes and even god‑level monsters.

He is functionally invulnerable in combat: he may get dirty or knocked aroundbut he almost never takes visible damage.

His basic punches casually obliterate dragon‑level monsters or send them flying over the horizon.

He has no formal martial arts training and fights with simpledirect movementsbut his raw strengthspeedreaction timeand perception render technique differences almost irrelevant.

He can see and react to movements that are invisible to normal humansand even in deep darkness he can clearly perceive distant objects.

He shrugs off psychic forces powerful enough to bend citieshas resisted reality‑cutting dimensional blades with two fingersand can casually interfere with space‑time “gimmicks” like dimensional portals.

Saitama’s strength also appears to have no upper limit and grows explosively when his emotions spike.

During his battle with cosmic‑powered Garouhe rapidly escalates from already absurd levels to the point where a “serious sneeze” blows away the gas layers of Jupiter and a fart becomes a rocket‑level propulsion system for spaceflight.

By the narration’s own admissionhis power curve during that fight increases to more than 100 times his pre‑battle leveleven though he was already overpowered before.

This terrifies Garouwho has himself one of the highest growth rates in the series and still cannot keep up.

Despite all thisSaitama’s intelligence and knowledge remain extremely average.

He routinely fails written examsmisjudges social cuesand is almost comically bad at strategythough his battle instincts are sharp in a straightforward way.

Saitama rarely needs techniques because his casual attacks are enoughbut the series gives names to a few “moves.”

Basic Techniques

Normal Punch

A simple straight punch.

Almost any monster hit by this either explodesdisintegratesor is hurled far into the distanceusually dying instantly.

Consecutive Normal Punches

A flurry of rapid punchesoften delivered with both hands.

Anything struck is reduced to paste or shredded into bits; this is still considered “normal” by Saitama’s standards.

“Serious” (Maji) Series

These are Saitama’s named “serious” moveswhere he stops holding back quite as much.

The names sound plainbut the raw power behind them turns each act into a cataclysmic technique.

Serious Punch (Maji Naguri)

Saitama’s first and most iconic serious move: a full‑power punch (still not necessarily his absolute maximum).

Its shockwave alone can tear apart planet‑busting energy beamssplit oceansand slice apart clouds stretching over continents; when clashed with Garou’s copythe combined blast would have annihilated multiple stars if not redirected.

All‑Directions Serious Punch

A rapid‑fire barrage of serious‑level punches from all directionsusing afterimages and extreme speed.

It overwhelms enemy defenses and saturates the battlefield with destructive force.

Serious Sideways Jumps

Saitama performs lateral shuttle‑runs so quickly that he creates numerous afterimages and devastating shockwaves.

He uses this to casually blitz speed specialists like Onsoku no Sonicdefeating them simply by crossing their path.

Serious Table Flip

He overturns the “ground” over an enormous area like flipping a dinner tablesending terrain and debris flying high into the air.

In the remade manga he even peels up the surface of Jupiter’s moon Io with thiserasing vast stretches of its crust.

Serious Headbutt

Saitama meets an incoming attack with a headbutt at full strengthusing it as a devastating counter.

Given his durabilitythe opponent always loses this clash.

Serious Water Gun

Saitama mimics a child’s “water pistol” hand motionbut channels immense power through liquid.

Using magma instead of waterhe casually cancels out Orochi’s planet‑level “Gaia Cannon” energy beam.

Serious Sneeze

An involuntary sneeze that now carries power greater than his earlier Serious Punch.

Used after his growth during the Jupiter battleit blows off Jupiter’s outer gas layers and horrifies Garou.

Serious Spin

Saitama rapidly spins his bodygenerating a tornado‑like vortex that destroys surrounding foes.

He uses it to clear hordes of robots in an instant.

Serious Whack‑a‑Mole

He stomps repeatedly at high speedcrushing multiple underground or small enemies at once.

Serious Squat

He performs a powerful squat jump in midairkicking or launching an object with his legs in the process.

Other Notable Moves and Concepts

“Water Flowing Carbonated Fist”

A fake martial arts name Saitama improvises when he enters a martial arts tournament disguised as Charankohaving misremembered Bang’s “Water Stream Rock Smashing Fist.”

It is not a real ; he continues to fight with his usual plain punches.

Zero Punch (“Zero‑Pan”)

A conceptual “punch” tied to time travel.

Empowered by the technique he learns from GarouSaitama reaches a state where his decisive blow effectively lands “before it is thrown,” reversing causality and letting him undo an apocalyptic timeline.

Saitama demonstrates a wide range of absurd feats beyond simple punching.

He has:

– Survived being kicked from Earth to the Moon and backjumping from the Moon to Earth using precise trajectory control.

– Remained calm and functional in vacuum and near absolute‑zero temperaturesonly complaining that it is “a bit cold.”

– Used a fart for thrust in space to catch up with Garou’s teleportation jumps.

– Physically grabbed and kicked around dimensional portals and forcibly entered other dimensions.

– Casually bench‑pressed barbells with miniature black holes as weights in a color spreadimplying the ability to lift objects with mass comparable to or greater than planets.

– Broken the “fourth wall” by commenting on how many panels a scene tookhinting at meta‑awareness.

He can precisely adjust the force of his attacks when ordered to limit collateral damagesuch as crushing a giant meteor so that the fragments miss the city as much as possible.

Yetmore often than nothis sheer presence leads to massive unintended destruction around him.

Interestinglyweak or arrogant characters almost always underestimate him on sightwhile truly powerful beings (dragon level and above) often sense something terrifying and “unknowable” about him at a glance.

Those who survive long enough to realize his true level are usually left in shock or despair.

Saitama is a loner by nature and seldom seeks companionshipbut strong or interesting people gravitate toward him.

Genos

Genos is Saitama’s self‑proclaimed disciplea serious young cyborg who idolizes him as “Sensei.”

After seeing Saitama casually slap away Mosquito MusumeGenos begs to become his student and later moves into his cramped apartmentbringing money and appliances.

Saitama treats Genos in a mostly hands‑off manner but will scold him when he causes troublesuch as doing reckless “private duels” with Sonic.

Genos’s faith is absolute: he believes that if Saitama ever losthumanity would already be doomedand he constantly seeks Dr. Kuseno’s upgrades in hopes of approaching his master’s level.

Onsoku no Sonic

Onsoku no Sonic is a self‑proclaimed rival who isin realitycompletely outclassed by Saitama.

Their first encounter ends with Saitama accidentally smashing Sonic’s groin while deflecting an attackand subsequent rematches see Sonic defeated by nothing more than Saitama’s shuttle‑runs or casual counters.

Saitama mostly finds Sonic annoying and often forgets his nameonce calling him something like “Joint Panic.”

StillSonic trains obsessively for a rematchconvinced that he can one day surpass this “unknown” hero.

Bang

Bang (Silver Fang) is an elderly S‑Class martial arts master who recognizes Saitama’s true strength almost immediately.

He repeatedly tries to recruit Saitama (and Genos) into his dojoeven offering them room and boardand treats Saitama as a friend.

Bang sees enormous untapped potential in Saitama and views him as someone who still has room to grow despite already being beyond S‑Class.

He occasionally hangs out at Saitama’s placecooks hot potand even unintentionally annihilates Saitama’s beloved cabbage in the process.

Unlicensed Rider

Unlicensed Rider is a C‑Class hero with no powers who bravely faces impossible threats on a bicycle.

Saitama’s respect for him is deep because Rider embodies Saitama’s own image of a hero: someone who stands and fights despite having no chance to win.

After Rider is nearly killed by Shinkaiou (Deep Sea King)Saitama personally carries himpraises his gutsand later visits him in the hospital.

The two are hinted to have been middle‑school classmatesthough neither seems to realize it.

King

King is widely known as the “strongest man on Earth” but is secretly an ordinary otaku whom Saitama once saved.

Saitama and King are now close friends who spend a lot of time playing video games togetherwith Saitama almost always losing.

King is one of the few people Saitama opens up to about his boredom and existential angst.

IronicallyKing—who has no real combat power—delivers some of the most important lectures to Saitama about heroism and personal growth.

Fubuki

Fubukileader of the Blizzard Groupinitially approaches Saitama as a “rookie crushing” B‑Class top‑ranker who wants to recruit him.

Her psychic attacks fail completelyand Saitama turns the tables by criticizing her reliance on her group and her obsession with rank.

After thisshe becomes a recurring “acquaintance” who often drops by to recruit him againdrag him into Association politicsorunintentionallypay for his meals when he “forgets” his wallet.

Saitama treats her with a mixture of indifference and mild concernsometimes running away and leaving her to pick up his tabsbut he also steps in to protect her and her team from Terrible Tornado and other threats.

Terrible Tornado

Terrible Tornado is Fubuki’s elder sister and an overwhelmingly powerful esper ranked second among S‑Class heroes.

When they first meetshe dismisses Saitama based on his rank and tries to push him aroundwhile he mistakes her for a bratty child and calls her “kid,” infuriating her.

Their later fighttriggered when Tornado tries to kill Fubuki’s prisoner Psykos in front of herbecomes a sprawling clash where Saitama tanks her full telekinetic wrath and drags her out into a desert to minimize civilian damage.

He lectures her for recklessly destroying property and for treating allies poorlyand although she blustershis words and his immovability clearly get under her skin.

Hero Name Victims’ Association

Because he hates being called “Caped Baldy,” Saitama joins a group of heroes whose official names are embarrassing.

They accept him as an executive member and try to organize a protest against the Association’s naming divisioneven threatening to “tear down the organization” if they do not get an apology.

The group also leans on Saitama’s hidden combat power when situations get dangerousrelying on him as their strongest member.

Senkou no Flash

Senkou no Flash is an S‑Class speedster ninja who quickly notices Saitama is far stronger than he looks.

He insists on “training him as a disciple” after a sparring match that he technically “wins” but that makes it clear Saitama is holding back.

FlashGenosand Saitama end up bickering over who gets to follow or train whomwith Saitama ignoring most of it and using Flash for directions in the labyrinth beneath the Monster Association.

Flash’s pride is repeatedly shaken as he realizes just how casually Saitama keeps pace with him.

Black Sperm and Overgrown Rover

After the Monster Association arca severely weakened Black Sperm and Overgrown Rover (now small and dog‑like) end up following Saitama.

Rover becomes his petwhile Black Sperm tries to survive by grovelingacting cuteand clinging to Saitama in the Hero Association apartments.

Saitama is mildly fond of Rover but finds Black Sperm annoying and creepy.

Neverthelesshe tolerates them as roommates/petsunintentionally sheltering former dragon‑level threats.

Manako

Manako is a smallmulti‑eyed monster from the Monster Association who ends up guiding Saitama and Flash through the underground.

Saitama treats her like a walking flashlight and snacks companionsharing hunger complaints and talking about food.

He later worries a bit about what happened to her after the Association fallsbut when Flash suggests going to look for herSaitama initially tries to blow it off as “too much trouble.”

Eventually they do find hershowing that even his laziness has limits when a familiar face is on the line.

Blast

Blastthe elusive number‑one herocrosses paths with Saitama only briefly.

Saitamawho barely pays attention to rankingssimply calls him “that Blast guy” and wonders why he knows teleportation tricks.

Blast recognizes Saitama’s terrifying raw power and is careful around himwarning others not to get close during the Saitama vs. Garou clash.

He and his companions have to work together to redirect the energy of Saitama and Garou’s clashing Serious Punches away from Earth.

House of Evolution

Chasing a mosquito that annoyingly escapes him leads Saitama to cross paths with Genos fighting Mosquito Musume.

After Genos nearly self‑destructsSaitama casually slaps the monster out of the sky in a single hitastounding Genos and setting up their teacher‑disciple relationship.

When House of Evolution monsters like KamakyuriKaeru OtokoNamekujarasuGround DragonBeast King (Juu Ou)and Armored Gorilla attackSaitama crushes them with ease—using Consecutive Normal Punches to reduce Beast King to chunks and digging Ground Dragon back out of the earth just to finish him.

He and Genos then storm the House of Evolution basewhere Saitama annihilates Asura Kabuto with one punch after explaining his “routine” to a disbelieving audience.

Hammer‑Head and Onsoku no Sonic

When Hammer‑Head’s “Paradisers,” a group of bald anti‑work terroristsappear on TVSaitama is furious that they are ruining the image of bald guys like himself.

He hunts them downeasily crushes Hammer‑Head’s battle suitand lets him go after extracting a promise never to return to crime.

Onsoku no Sonic then mistakes Saitama for a Paradiser and attacks him.

Saitama treats Sonic as a nuisancedismissing his cred and accidentally smashing his groin in a counterprompting Sonic to swear eternal rivalry.

Joining the Hero Association

After Sonic points out that nobody knows Saitama despite his featsand Genos explains the hero licensing systemSaitama agrees to take the Hero Association exam.

He scores perfect marks on the physical tests but nearly fails the written examentering as a bottom‑ranked C‑Class hero with only 71 points out of 100.

His dismissive attitude toward Association lectures angers A‑Class hero Sneckwho attempts a “newcomer crushing” ambush.

Saitama defeats him effortlessly and later spars with Genosstopping a death‑blow at the last moment and vaporizing the landscape behind himproving to Genos just how massive the gap between them really is.

Deep Sea King (Shinkaiou)

When the Deep Sea King and his army invade J‑Citymultiple heroes fall before him.

Unlicensed Rider makes a hopeless last standand Saitama arrives just as Rider is crushedlifting him and praising his courage.

Saitama one‑shots Deep Sea King with a single punch that pierces the monster’s torso.

He then deliberately claims he only won because the previous heroes had weakened the enemytaking all the credit and blame himself so that civilians will continue believing in the injured heroes.

Dark Matter Thieves and Boros

When the alien armada of Lord Boros (Boros) annihilates City ASaitama leaps onto the massive spaceshiptears through traps and alien elites like Groribas and Geryuganshoopand confronts Boros in his throne room.

Boros is the first opponent who survives Saitama’s opening Normal Punch thanks to regenerative abilities and sealed armor.

Their battle sees Boros reach “Meteoric Burst” modekicking Saitama to the Moon and attempting a planet‑destroying beam“Collapsing Star Roaring Cannon.”

Saitama responds with a Serious Punchblowing away the beamripping apart global cloud coverand ultimately killing Boroswho dies satisfied that he finally met someone far stronger than himself—and bitterly notes that Saitama was still holding back.

Martial Arts Tournament and Gouketsu

Disguised as Charanko to enter the Super Fight martial arts tournament and “study martial arts,” Saitama casually humiliates fighters like ZakosSour Face (Niga‑mushi)Chozeand the dragon‑level Bakuzan with effortless slaps and throws.

He loses by technicality when his wig is knocked off mid‑fight with Suiryubut then returns when monsters attack the stadium.

Saitama rescues Suiryu from Bakuzan and Gouketsuobliterates Bakuzan in front of himand decapitates Gouketsu off‑screen with a single blowhis severed head landing back in the arena.

Suiryuinspired by Saitamaswears to become a real hero and even begs to become his disciplean offer Saitama flatly refuses.

Hero Hunter Garou and Monster Association

Throughout the Garou arcSaitama repeatedly encounters Garou without realizing who he isknocking him out with casual chops on multiple occasions.

Meanwhilehe participates in the Association’s raid on the Monster Associationwandering the labyrinth in search of a “boss” worth fighting.

He beats Overgrown Rover with a single hitscares the dragon‑level dog so badly it becomes docileand kills the Monster King Orochi underground with essentially no effort—without even realizing that Orochi was the King.

Along the wayhe teams up (reluctantly) with Senkou no Flash and the monster Manakousing Manako as a flashlight and snack‑talk buddy.

He is present for many of the chaotic battles undergroundcasually dispatching revived monsters like Gale Wind and Hellfire Flame and bailing out child hostage Waganma with minimal fuss.

He later destroys Elder Centipede (Elder Centipede’s ancestorElder Centipede itself in the remake) with a Serious Punch after King lures it into positionstunning everyone watching.

Cosmic Garou and Time Reversal

In the climaxGarou accepts power from an entity called “God” and awakens into a cosmic form capable of nuclear‑scale attackscopying Saitama’s techniques and striking him hard enough to draw a rare drop of blood.

Saitama’s anger and grief after seeing Garou kill Genos and other heroes cause his power to skyrocketand Blast teleports both combatants to space to prevent Earth’s destruction.

On Jupiter’s moon Io and in spaceSaitama grows absurdly stronger in real timematching and surpassing Garou’s rapidly evolving martial arts and energy attacks.

He counters Garou’s copied Serious Punch with his ownunleashes Serious Table Flip and Serious Sneezeand literally splits Jupiter’s gas layers by sneezing.

Garou eventually realizes that Saitama’s growth is exponential and unbeatable; in despair and regret over the collateral damage he caused (including killing the child Tareo)he passes Saitama a technique to manipulate his own subatomic particles and travel back in time.

God kills Garou to reclaim its powerbut Saitama successfully time‑jumpsmerges with his past selfand lands a decisive blow that strips Garou of God’s influence before the dark future can occur.

The only trace of the erased timeline is Genos’s damaged core that traveled with Saitamawhose recorded memories of the doomed future flow into present‑day Genos.

Genosnow the only one who remembers everything that “never happened,” tries to explain it all to a confused Saitamawho mostly tells him to stop because the explanation is giving him a headache.

Neo Heroes and Moving to A‑Class Housing

After the Monster Association arcSaitama is promoted to A‑Class 39th and given a new official residence in a high‑grade Hero Association apartment complex in City A.

While salvaging his belongings from the ruins of City Zhe encounters a shrunken Black Sperm and a much weaker Overgrown Rover and ends up taking them in as pseudo‑pets.

Back in City ASaitama and his entourage accidentally destroy part of the Association’s robot security systemleading to a brief interrogation.

He then meets three A‑Class neighbors—Butterfly DXChain’n'toadand Forte—who attempt to haze him but are themselves humbled when Forte is accidentally run over while challenging Saitama to a fight.

Saitama accompanies Fubuki to the secret monster prison where Psykos is heldending up embroiled in Fubuki’s confrontation with Terrible Tornado over Psykos’s fate.

He spends most of the resulting Tornado vs. Fubuki Group chaos punching out escaped monstersthen hauls Tornado far from cities to keep her destruction away from civilians.

When Tornadoalready injured from prior battlespushes herself too far and nearly collapsesSaitama helps Fubuki’s team frame this moment as their one chance to break free from Tornado’s overbearing control.

Laterhe chases after Tornado to talkonly to get into a fresh argument when she accuses him of hiding his true strength and insists she could beat him “in five seconds” if she were healthy; Saitama just looks at herunimpressed.

Saitama’s face is notoriously simple in the original webcomicoften resembling a quick doodleand even in the anime characters jokingly say he looks like someone you could draw in 20 seconds.

Howeverwhen he becomes seriousthe art tightens into a much more detailed and handsome designemphasizing the gap between his usual slacker vibe and his true nature.

The city he lives inCity Zis drawn to roughly resemble the shape of Saitama Prefecture (a pun on his name).

His name literally comes from Saitama Prefectureas the creator wanted a mundanegeographically inspired name.

In both the original and remade mangaSaitama struggled to fit into groups even in middle school and nursed a rebellious resentment toward the unfairness of the world.

Before becoming a herohe worked various odd jobs like construction day labor and convenience store part‑time shiftsbarely scraping by.

Within Japanese anime culture (in‑universe and out)Saitama has become an archetype of the “overpowered protagonist done right”: unbeatable but emotionally groundedmore concerned with grocery sales than glory.

Even other series reference him: in The Vampire Dies in No Timeobvious parodies of Saitama and his “Serious Punch” show upand in crossover fan discussions he is often compared to other “strongest heroes” like those from major comic universeswith “One‑Punch vs. everyone” debates becoming a meme.

In the video game One‑Punch Man: A Hero Nobody KnowsSaitama’s in‑game power is so extreme that the designers make him arrive late to battles.

Players must survive with two weaker heroes until Saitama finally shows upat which point he can one‑punch almost any foe while barely taking damage himself; the only counterplay is to win before he arrives or run out the clock.
