History Characters / OnePunchManMainCharacters

* HeroWithBadPublicity: Played straight and later invoked by the man himself. Because of his anonymity and the fact that he beats villains without any effort, people have accused him of being a fraud who isn't a "real" hero. He saves a town from a meteor but the debris destroys the city anyway, although everyone lived. After he kills the Sea King, a random {{Jerkass}} starts mocking the heroes who couldn't beat him before Saitama showed up. Saitama decides to paint himself as a selfish GloryHound so said heroes get the credit he feels they deserve at the cost of his own reputation.

* WorldOfCardboardSpeech: He makes one after some people say a lot of bad things about him, never mind that he saved them from a giant meteor in the first place.
--> '''Saitama:''' Let me make one thing clear! I'm not working as a hero to get you morons to admire me! I do it cause I want to!

* StrongAndSkilled: Saitama is the most powerful character in the whole series, perphaps even the whole universe. His godlike strength, speed, agility, durability and senses are unmatched. He is also surprisingly skilled with his powers, with enough control to avoid killing a human and enough cunning to have his own sheet of "techniques" where he uses his superhuman abilities in multiple ways. And even though his fighting style is basic, he is a experienced who can fight smart if he wants to. Using brute force is just a preference for him.

And even though his fighting style is basic, he is a experienced who can fight smart if he wants to. Using brute force is just a preference for him.

* NiceJobBreakingItHero: In "Road to Hero", Saitama discovers he can make money to pay his rent by turning in all of the criminals housed up in the apartments next to his, and proceeds to beat all of them up. When he shows his caught criminals to the landlady, [[RealityEnsues she berates him for getting rid of her sole source of income]], and proceeds to kick him out anyway.

* InexplicablyAwesome: Saitama is basically the most powerful person in the universe, and there's no logical explanation as to how he got to be that. In his view, it's [[CharlesAtlasSuperpower because of his training]], but it's pointed out various times that a normal human couldn't possibly become that strong just by following a moderately-tough (even by real-life standards) training regimen.

* GermanicEfficiency: According to [[WordOfGod Murata]], Genos would be German in real life; while he does has his moments of overlooking things in battle (i.e. to where he constantly gets his ass kicked), Genos is always willing to improve himself as a fighter with the utmost efficiency.

* CripplingOverspecialization: He really wants to emulate Saitama, so he focuses on pure destructive power and trying to blow up the enemy with as much firepower as he can instead of improving his fighting skills. The result is that he comes across more as a demolition man who's great at destroying the scenery and buildings, but not so great when it comes to fighting mano-a-mano.

* DoomedHometown: He explains that when he was a kid, a rogue cyborg destroyed his home town and everyone he knew, leaving him mortally wounded.
* DragonKnight: [[spoiler: His Monster arc upgrades has sharper and more jagged arms than compared to previous forms with 3 large protrusions on each shoulder resembling knives. In this upgrade he takes on an almost draconic appearance, which is lampshaded when he turns the power up during the fight with Psykorochi and emits a BattleAura that resembles, in the words of an onlooker, an azure dragon. However, this upgrade only lasts for 10 seconds before his core explodes]].

* LastNameBasis: "Saitama" is his last name. His first name has yet to be revealed.

** To Tatsumaki. Both are the characters that have ArtShift between goofy webcomic and serious detailed one, look non-threatening but have incredible power, and have a weaker student in Genos and Fubuki respectively, but they have some opposites, where Saitama had normal life before becoming a hero, has a calm demeanor, is low ranking and gets no respect, and fights entirely physically, but Tatsumaki had traumatic past, is moody and easily annoyed, second highest rank in the Hero Association, and uses her psychic powers.

* HeroOfAnotherStory: Played with in-universe. Most, if not all of his accomplishments are credited to other heroes, and as such, both the general populace and most of the Hero Association members barely know who he is, then there's the ones that think he's a hack, while there's only a select few who know him and respect him for what he's done. By design, his fellow heroes are TheProtagonist of the stories that the in-universe public sees and they are ''tiny'' compared to Saitama (who is TheProtagonist of the story we, the out-of-universe public, sees) who would be a ''titanic'' background character of sorts.

** Thankfully this is mostly averted when it comes to his fellow heroes, especially those in the S-Class. They tend to have enough combat expertise to know he's the real deal from the start (Bang) or discover it for themselves the hard way (Tatsumaki and Fubuki). Most of the higher ups in the Association also seem to think he was placed low due to a fluke and that he should be much higher since he utterly destroyed (quite literally) his physical exam.
* HeroismWontPayTheBills: He receives a monthly stipend once he joins the Hero Association. Despite that, he spends an entire chapter trying to get pocket change to try a drink from a vending machine. Before joining the Hero Association, he did not have an apparent source of income. WordOfGod reveals that he made a living doing troublesome part time jobs, living frugally with his savings, and living off vegetables given to him by people he saved. Despite Genos moving in with him and paying his rent, his standard of living hasn't changed because [[WordOfGod according to the author, Saitama refuses to spend any of Genos's money]].

* HumbleHero: Saitama is very humble, as he purposefully let the masses turn against him for the defeated heroes to be given credit for their efforts against the Deep Sea King, even claiming that they had weakened the monster before his arrival. He did the same for the police station, killing a monster while disguised as a police officer, despite potentially gaining much fame had he revealed who he actually was. He also did not mind that King took credit for all of his achievements. Despite his humility and modesty, he still retains some sense of pride, since he wants to beat up Garou after realizing that the latter didn't want to hunt him during his hero hunt, just because he is a low-ranking hero who is not worthy to be hunted. However, Saitama's desire to pummel Garou mostly comes from his desire for an exciting and challenging fight, not for his pride as a powerful hero. Even though he expresses faint protests at it, there's the fact that his apartment is open for all heroes who he's met, to the point where there's a RunningGag of just interlopers crashing in his apartment.

* IJustWantToBeBadass: [[DeconstructedTrope Deconstructed]] and Parodied. Saitama's original motivation for becoming a hero in the first place was just to be a cool, powerful badass and fight strong enemies, like many a {{Shonen}} hero. Well, needless to say, he succeeded with ''flying'' colors and now he's so badass that he doesn't know what to do with himself. That and he doesn't seem too interested in lookin for anything else.
* ImprobableWeaponUser: He once [[EyeScream defeated]] a giant crab monster using only his neck tie.

* InexplicablyAwesome: Saitama is basically the most powerful person in the universe, and there's no logical explanation as to how he got to be that. In his view it's [[CharlesAtlasSuperpower because of his training]], but it's pointed out various times that a normal human couldn't possibly become that strong just by following a moderately-tough (even by real life standards) training regimen.

** He became a super hero for rather selfish purposes, is lazy, and seems to care more about having a fun fight and will sometimes ignore problems in his city until he's directly involved, but he ''does'' genuinely want to protect the world. He's just fallen into a lull because of how easy it's become.
** While he doesn't always act like a paragon of heroism, some of his lines imply that, while he may not act like it, his heart is in the right place. One of the best to date? "If the heroes run and hide, who will stand and fight?" During his dream fight against the subterraneans, while he admits that he's just a hero for fun, he also says the surface is under his protection.
** He's also quick to let people think he's a phony, just so that the other heroes who put their lives on the line and nearly died would get the respect they deserved. He doesn't care about getting recognition from the public, but thinks the other heroes ''should'' get it.

* TheLeader: He became the leader of the Hero Name Victims Association due to being their highest ranked member.

* LimitedWardrobe: He seems to have only a few sets of clothing, if you exclude the special chapters. There's also his iconic hero outfit, made for him by his old tailor.

* MySuitIsAlsoSuper: Setting aside Saitama's own improbable power, his superhero suit is also incredibly durable. The only time it's ever suffered ClothingDamage was during the fight with Boros, where his cape was torn in half. Beyond that it's rare to see so much as a speck of dirt on it, regardless of what attacks he lets the enemies throw pointlessly at him, or even the attacks he himself makes. Surprisingly, an individual with no connections whatsoever was able to procure such suit, [[CheapCostume all while making himself look lame]].
* NiceJobBreakingItHero: In "Road to Hero", Saitama discovers he can make money to pay his rent by turning in all of the criminals housed up in the apartments next to his, and proceeds to beat all of them up. When he shows his caught criminals to the landlady, [[RealityEnsues she berates him for getting rid of her sole source of income]], and proceeds to kick him out anyways.

* BornUnlucky: Genos has the misfortune of never being able to catch a break. His home was destoyed by a cyborg, his upgradfes are never enough, and despite his immesnse strength he can't put away power enemies.

* TheAce: A highly [[DownplayedTrope downplayed]] example, almost towards an inversion. While the entire public is [[WeirdnessCensor ignorant]] of Saitama and his achievements, the very few individuals who are aware of his true prowess revere him as one. Saitama single handedly broke all preexisting records in the Hero Association's physical examinations, and in just over 65 days went from C Class to A Class. On a regular basis, Saitama can achieve several feats which surpass those of all S Class heroes. A recurring theme in the manga is that, in any given arc, Saitama almost always defeats the strongest [[BigBad antagonist/opponent]] of that arc. See WorldsStrongestMan below.
** Doubly inverted. While Saitama looks unimpressive and is far from being the IdealHero, he is the most powerful hero who always wins. Only two beings ever came close to his power and Saitama [[CurbStompBattle defeated both of them]]. Not to mention, he is unusually perceptive about the human mind and offers simple minded wisdom to Genos.

** According to WordOfGod, Saitama lacks technique and proper coordination and would do badly in team sports. However, this doesn't affect his ability to fight monsters as his immense strength, speed, reflexes, durability, stamina, excellent sight and hearing more than make up for this.

* AdaptationalAttractiveness: His past-self three years ago in the reboot manga. He's not actually that bad looking bald either, but the majority of the time he's [[PaintingTheMedium so lazy that not even his artist can be bothered to finish his artwork]] making him look like a Muppet or a doll for some reason.
* AlmightyJanitor: The strongest hero bar none, but started off as a C-Class hero due to a poor written score on the entrance exam. Not to mention that all of his observed victories are seen by the public as nothing more than flukes. His unobserved victories were all attributed to someone else, who is now the most feared hero in the entire organization, [[spoiler:despite being an otherwise ordinary person.]]

* CharacterDevelopment: Starts off as a PunchClockHero who only cares about [[BloodKnight the thrill of the fight]], but eventually grows into a genuinely heroic person who [[HeroWithBadPublicity makes himself unpopular]] so that other people can get the respect that they deserve.

* ComicallyInvincibleHero: Played with and explored -- part of the humor of Saitama's character is that he is so outrageously overpowered that his fights are humorously anti-climatic. He wins all his fights ridiculously easy, even the mightiest foes pose no challenge to him, so he does not take his hero work seriously, goes through everything with little to no effort, and yearns for an opponent that can provide him with a challenge. Saitama is disappointed he might never find a fight that will seriously challenge him, the lack of worthy 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. The combination of his attitude, unstoppable power, and "unimpressive" appearance often causes his battles to become anticlimactic. He even tells the second monster he curbstomped that his attaining the ultimate power has made his life boring as hell.

* DramaPreservingHandicap: When individual enemies have a presence beyond a few minutes of screentime, Saitama has a tendency of having a hard time getting to the fight due to a poor sense of direction, leaving other heroes to shoulder the weight of the fight.

* DreamingOfThingsToCome: Played with and parodied. He has a dream about saving the world from the mole people who've risen from under the ground in order to wipe out humanity, and having a truly thrilling battle in the process. When he wakes up, the very same mole people from before are in the midst of launching their attack [[spoiler: but, as it turns out they're actually hilariously inneffectual, and that's before Saitama decides to fight them to reenact the thrilling fight in his dream.]]
* DudeWheresMyRespect: He's almost never given credit for defeating a lot of the major villains early on (in fact, [[spoiler:King's "victories" are almost all Saitama's]]), though he finds out it's mostly because he wasn't a registered superhero. In addition, he's unaware that the creation of the Hero Association is down to him. Even after registering, the people rarely give him credit for his victories, or are unappreciative when they do. In some cases, Saitama will deliberately avoid getting credit when he thinks others deserve it more. He also tends to neglect to report any monsters he defeated to the association, or have no witnesses around to see what he does. That said, Saitama still moves up in rank after each victory, because the Hero Association at least recognizes that he is responsible ([[ThePeterPrinciple and if he's not, they figure promoting him will prove it]]). He's also slowly gaining the respect of various heroes, who do realize that Saitama really is as powerful as advertised.

** To Garou. Both of them have a strong sense of morality and justice, albeit manifested in different ways. While Saitama wanted to be like a hero from his childhood who fought villains, Garou wants to be a monster who defeats heroes. While Garou is a genius fighter and a prodigious martial artist, Saitama an untrained fighter, albeit with good fighting skills. Furthermore, Garou can enjoy the feeling of losing in order to improve himself to become stronger in most of his fights, while Saitama desires to have a worthy opponent to find the rush of excitement he once had while he was training.

* HeroismWontPayTheBills: He receives a monthly stipend once he joins the Hero Association. Despite that, he spends an entire chapter trying to get pocket change to try a drink from a vending machine. Prior to joining the Hero Association, he did not have an apparent source of income. WordOfGod reveals that he made a living doing troublesome part time jobs, living frugally with his savings, and living off vegetables given to him by people he saved. Despite Genos moving in with him and paying his rent, his standard of living hasn't changed because [[WordOfGod according to the author, Saitama refuses to spend any of Genos's money]].

* HumbleHero: Saitama has been shown to be very humble, as he purposefully let the masses turn against him in order for the defeated heroes to be given credit for their efforts against the Deep Sea King, even claiming that they had weakened the monster before his arrival. He did the same for the police station, killing a monster while disguised as a police officer, despite potentially gaining much fame had he revealed who he actually was. He also did not mind that King took credit for all of his achievements. Despite his humility and modesty, he still retains some sense of pride, since he wants to beat up Garou after realizing that the latter didn't want to hunt him during his hero hunt, just because he is a low-ranking hero who is not worthy to be hunted. However, Saitama's desire to pummel Garou mostly comes from his desire for an exciting and challenging fight, not for his pride as a powerful hero. Even though he expresses faint protests at it, there's the fact that his apartment is open for all heroes who he's met, to the point where there's a RunningGag of just interlopers crashing in his apartment.

* IWorkAlone: Highlighted in one of the extra chapters. Saitama doesn't value teamwork very much and his teammates are ignorant about his power. WordOfGod states that Saitama would do poorly in team sports. He was also hesitant to accept Genos as his disciple, but nevertheless, he does seem to care for him and his small group of hero friends.

* LineOfSightName: His hero name "Caped Baldy" is due to the fact that, well... [[ExactlyWhatItSaysOnTheTin he's a bald guy with a cape.]] Compare this to Genos' "Demon Cyborg" because of his trait of fearlessly confronting enemies without regard for their numbers or strength.

* MySuitIsAlsoSuper: Setting aside Saitama's own improbable power, his superhero suit is also incredibly durable. The only time it's ever suffered ClothingDamage was during the fight with Boros, where his cape was torn in half. Beyond that it's rare to see so much as a speck of dirt on it, regardless of what attacks he lets the enemies throw pointlessly at him, or even the attacks he himself makes. It's surprising that an individual with no connections whatsoever was able to procure such suit, [[CheapCostume all while making himself look lame]].

* OffscreenMomentOfAwesome: After Gouketsu wrecks the martial arts stadium and heads back to the Monster Association's hideout, Suiryu warns Saitama not to go after the four-eyed giant. Saitama casually brushes off his warning in order to be a real hero. With the manga being told from Suiryu's perspective, at this point, all that's shown is a severely injured Suiryu listening to a few rumbling sounds, followed by Gouketsu's head landing in the arena in Chapter 75. And Gouketsu's pierced corpse isn't shown until Chapter 79, when Gyoro Gyoro investigates why the giant hasn't returned from his recruitment drive.

* OvershadowedByAwesome: Despite being the most powerful person in the world and possibly the universe, his plain looks and penchant for finishing fights effortlessly in one hit mean that most people overlook him for the more conventional badass-looking characters. He's also willing to paint himself as a hero who takes credit for others' deeds in order for people to appreciate the efforts of those heroes who truly have given their all to save people, in contrast to his effortless work. In short, he is invoking this trope upon himself, in part intentionally.

* PerceptionFilter: Seems to have one imposed upon him; he has a ''really'' hard time having his achievements recognized, especially in light of his frankly absurd power and ability. This mostly holds true for the general populace, however, as his fellow heroes seem to at least respect and appreciate his skill and strength.

** And as pointed out above, other characters are quick to point out that Saitama's insistence that he somehow got his incredible strength by just training every day is just absurd. No normal human could possibly gain the strength to do something like punch an entire mountain range to pieces in a single blow without something else getting involved.

* SuperSenses: To a point. Saitama is able to very casually follow enemies that are moving so fast they are barely a blur, and can even accurately track enemies underground (who are trying their best to flee from him). However, he can usually find a fight only if someone points him at the right direction.

* TallDarkAndHandsome: In the reboot version of the manga, prior to becoming bald due to his training three years ago, he basically looked like a brunette version of Genos with brown-colored eyes.

* WhatYouAreInTheDark: Despite needing occasional good publicity in order to maintain his status as a hero, Saitama will far too often ensure that others get credit for his deeds.

* WorldsStrongestMan: Saitama is the titular One-Punch Man and the strongest character in the series. So far, no enemy has been able to injure him in any way, and almost no enemy has been able to survive a single earnest punch from him. A few enemies have survived punches from him, such as any human he has struck (whom he restrains himself against) and Boros, whom Saitama empathized with and held back against so as to give himself and Boros a satisfying and stimulating fight. Saitama's only power is that his body is far beyond human limits, allowing him to achieve astounding physical feats. His strength is so great that it vastly eclipses even artificial beings designed or bred specifically for superhuman combat, such as mechanical beings or the mutated warriors from the House of Evolution. Since no enemies have posed any real challenge to Saitama yet, the upper bound of his strength is likely even higher than it currently appears. While his power is only limited to heightened human traits - Saitama cannot fly or fire energy blasts - his superhuman abilities more than make up for the lack of variety in his powers. The only known person who might match Saitama is BLAST. As Boros puts it:

* ZeroApprovalGambit: After defeating the Deep Sea King, one obnoxious spectator calls into question whether the heroes were heroic at all. In order to stave off backlash against his fellow heroes and ensure the Hero Association continues to get funding and donations, [[spoiler:Saitama claimed that Genos and the other heroes softened up the Deep Sea King enough for him to kill him and take the credit. The other heroes became adored for their deeds and the Hero Association's future was ensured, at the cost of Saitama's reputation.]]

* CelibateHero: After his village was destroyed and everyone he knew killed, he dedicated himself fully to tracking down the killer. After meeting Saitama, he switched that slightly to being the strongest hero he can be. He was so dedicated that he got rid of all his component parts anyways. Furthermore, he hasn't shown any romantic interests either, fan shipping with Saitama aside. While he understands how people work like Saitama does, he dismisses most individuals and is as socially dead as Saitama.
* CharacterDevelopment: Downplayed. He started off as a cyborg bent on having revenge on the mad cyborg, to a much calmer person who now genuinely wants to protect people. But his doctor remarks that the hate in his heart is still not extinguished even if he has a master and a goal set.

* CripplingOverspecialization: He really wants to emulate Saitama, so he focuses on pure destructive power and trying to blow up the enemy with as much firepower as he can instead of improving his fighting skills. The end result is that he comes across more as a demolition man who's great at destroying the scenery and buildings, but not so great when it comes to fighting mano-a-mano.

* ExplosiveOverclocking: [[spoiler:In Monster arc he got an upgrade that allows him to fire a WaveMotionGun that can barely hold Psykorochi's own, but the upgrade only lasts for 10 seconds before his core explodes, killing him]].

* UnskilledButStrong: In combat, Genos mostly relies in as much firepower and mass destruction weapons he can use in order to destroy his enemies. While somehow skilled with his cyborg functions and experienced in his own, Genos rarely bothers to use actual tactics while fighting, and he tends to lower his guard a lot, allowing enemies to land critical damage on him. Lastly, he also refuses to learn martial arts from Bang, since as he puts it, he "searchs not for the art of self-defense but destructive power". '''Saitama''' shows more skill with his powers than Genos does with his mechanic upgrades.

** The strange part is that this seems to be an entirely subconscious ability. The first time he beat Garou, he hit him so hard that Garou's legs were embedded in the cement underneath him. Saitama didn't even know he was the hero hunter at the time and thought he was a common mugger. The thing is, if Saitama had hit anyone normal person with that blow, they would be very dead. Saitama not only missed this detail, but somehow knew just how hard to hit Garou to knock him out and not leave any permanent damage. If Saitama intends non-lethal damage, then 99% of the time, it's going to be non-lethal. It's doesn't matter how strong or weak his opponent is.

* GoodIsNotSoft: While he's a hero that genuinely cares about saving others, and is generally EndearinglyDorky when he's being serious about relatively normal things, Genos is still hostile and cold towards anyone he doesn't particularly care about, even [[spoiler: outright criticizing an H.A. official who comes to him for help on a private mission, saying that he's abusing his power before allowing him to talk about it. He doesn't get along with Flashy Flash either, fighting him when he visits Saitama. And throughout the series, Genos is usually seen threatening others over minor inconveniences, such as Charanko not bringing cabbage for the hotpot.]]

Originally an ordinary aspiring {{salaryman}}, Saitama was inspired to become a hero when he managed to save a big-chinned boy from a monster crab with nothing but his necktie. He trained for three years doing an ordinary if fairly intense regimen until his powers awoke and he lost all of his hair. Now he's become so powerful that, no matter the opponent, he can defeat them with a single punch. Because of this, he's grown bored with his life of super-heroism.\\\

What Saitama doesn't know is that the big-chinned boy he saved all those years ago was the grandson of [[BigGood a multi-millionaire]], who founded the Hero Association when he found out about the incident.

[[folder:Saitama/Caped Baldy]]

[[folder:Genos/Demon Cyborg]]

Genos was an ordinary young man until a rogue cyborg destroyed his home town and killed everyone he loved. He was mortally wounded, but a kind scientist saved his life and rebuilt his body. Genos traveled the world in the hopes of tracking down the cyborg responsible for killing his parents, but chooses to settle down with Saitama after a while in the hopes of also becoming more powerful. Whereas Saitama has raw, undeniable strength, Genos has everything else. That is, [[TheAce looks, intelligence, dedication, money, style, and appeal.]]

--->'''Saitama''': So you did have an "image of an ideal hero" inside of you. I see now. I now understand what you wanted to do. Even though you said you wanted to be a "monster of absolute evil"... What you really wanted to be was a hero. But you compromised and decided to be a monster. To bring about world peace, you took the easy route, thinking a monster's job was quicker and easier than a hero's. A monster's role is simpler after all, all you had to do was defeat heroes. It's perfect for someone with no confidence like you. BUT YOU CAN NEVER DEFEAT ME. Peace made by ruling the world with fear can't succeed as long as you can't defeat me. It will never work. It's absolutely impossible for you. Because if it's your compromised monster hobby vs my serious hero hobby, even if that's all I had, I still wouldn't lose! It was a mistake to lower the hurdle right before the goal. A half assed objective just can't succeed.

* CripplingOverspecialization: When it comes to battles, Saitama is practically invincible, but when it comes to challenges that don't involve physical fighting, he's nearly helpless.

** While he did only agree to being Genos' master on whim, Saitama feels bad that he can't really offer the cyborg anything valuable lessons to strengthen himself, and feels like his scamming the poor guy.

** While he did only agree to being Gonos' master on whim, Saitama feels bad that he can't really offer the cyborg anything valuable lessons to strengthen himself, and feels like his scamming the poor guy.

* EveryoneHasStandards: Discussed and parodied after he slugs Boros mid-speech.

* CripplingOverspecialization: When it comes to battles, Saitama is practically invincible, but when it comes to challenges that doesn't involve physical fighting, he's nearly helpless.

* AlwaysSomeoneBetter: ''He'' is the "someone" to ''everyone else''. Something of a RunningGag in the series, where ninja-for-hire "Speed of Sound" Sonic is very proud of his SuperSpeed, such that he is practically invisible to the naked eye. The problem is that he is the UnknownRival of Saitama. When Sonic tries to leap around unnoticed, Saitama easily watches him go. When he attempts a BackStab, Saitama inadvertently nails Sonic with a painful and embarrassing GroinAttack. When he revels in his ability to create ten 'speed clones' in a fight against Saitama and considers it his best chance to kill the hero, Saitama effortlessly creates ''hundreds of speed clones''. There's just no winning for Sonic, and the audience is expected to have a good laugh at his expense.

* ComicallyInvincibleHero: Played with and explored -- part of the humor of Saitama's character is that he is so outrageously overpowered that his fights are numerously anti-climatic. He wins all his fights ridiculously easy, even the mightiest foes pose no challenge to him, so he does not take his hero work seriously, goes through everything with little to no effort, and yearns for an opponent that can provide him with a challenge. Saitama is disappointed he might never find a fight that will seriously challenge him, the lack of worthy 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. The combination of his attitude, unstoppable power, and "unimpressive" appearance often causes his battles to become anticlimactic. He even tells the second monster he curbstomped that his attaining the ultimate power has made his life boring as hell.

* {{Hypocrite}}: Saitama usually has impeccable precision in finding out what a person lacks in order to have a more truthful and fulfilling life, without their heavy issues dragging them down, he has dished out basic advices on several key characters as the series progresses; however, Saitama isn’t very receptive of others trying give him a tip on how to enrich his life of continuous boredom, King gave a simple answer to his issue of feeling completely hollow as the strongest being in the world, unable to face any real challenge in his hero hobby, so he could just take another hobby and start from zero all over in that new venture, and continue to try new things until he finds something to enjoy; Saitama completely ignores King’s advice.
