! Saitama, "Caped Baldy"
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/opm_saitama.png]]
->''"Just a guy who's a hero for fun."''
->'''Voiced by:''' Creator/MakotoFurukawa
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 absurdly 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 a multi-millionaire, who was motivated to establish the Hero Association when he heard about the incident.
-----
* 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 so lazy that not [[UpToEleven 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.]]
* AndThenWhat: Achieved his IJustWantToBeBadass dream and became so {{badass}} that nothing posed a challenge to him anymore. Which turned out to be incredibly boring.
* AntiHero: Definitely a KnightInSourArmor. He has the power to completely change the world, but is ''way'' too lazy to do so. He's also quite cynical about the hero business (not that he's wrong about said business). However, without a doubt, he will do the right thing.
* ArtShift: Saitama is drawn as either a weird, stick figure, a slightly more detailed stick figure, or a fully drawn, highly detailed normal figure that matches the art of the other characters. It's all part of the joke that most of the time he does not look like the type of protagonist you'd see in a {{Shonen}} manga and his normally unassuming appearance belies his strength.
* BadassCape: Arguably the only thing his old tailor got right with his outfit.
* BadassNormal: He managed to defeat a crab monster with nothing but his shirt tie before he ever even started training.
* BadassTeacher: Not that he wanted to be one, but Genos considers him such. Saitama even comments that, despite [[IndyPloy making it up as he goes along]], Genos is eating out of the palm of his hand.
* BaldOfAwesome: In that his awesomeness is the reason he became bald in the first place.
* BatmanCanBreatheInSpace: {{Downplayed}} during his battle with [[AliensAreBastards Boros]]. [[spoiler:While he does seem to still need oxygen given how he takes the time to hold his breath and pinch his nose shut, Saitama suffers no other ill effects from being on the moon's surface after Boros kicks him there, even casually taking his time in figuring out how he was gonna get back]].
* BerserkButton: People commenting on his baldness tends to irk him. But a much grander button for him is heroes who act cowardly.
* BigBrotherMentor: Plays this role to Genos. Although Genos originally joined Saitama to learn the secret behind Saitama's strength, he instead learns compassion, humility and heroism. Saitama is a positive influence that is helping Genos transition from a vengeance-fueled {{Antihero}} into a [[TheCape true hero]].
* BigDamnHeroes: A reoccurring theme and pretty much how most story arcs end. Saitama is usually late and if other heroes are involved, they have probably already been beaten or are in trouble when he arrives. Biggest example is when he defeats the Sea King. As this series is a [[AffectionateParody deconstruction]] of the whole super-hero genre, this is probably intended. Besides, he isn't aware that he was behind the foundation of the Hero Association for saving the big-chinned person's boy from a monster crab.
* BloodKnight: Part of his depression about being so goddamn strong is that no opponent can give him a challenge anymore. Whenever he faces a seemingly strong opponent and defeats it in one punch, he laments that the opponent "kinda got his hopes up", examples being Asura Rhino and the Deep Sea King. He even had a dream that had him really enjoying the rush of fighting an opponent he thought was on equal footing.
* BookDumb: Saitama is not stupid, but he did so poorly on the written portion of the Hero Association entrance exam that he was placed in the lowest possible category of hero, despite his record-shattering performance during the physical portion. He scored a 100 on the physical, and a 42 on the book. Thus, he got a 71 (the cut-off was 70 points).
* BrickJoke: While talking with Genos before the training session, he wonders what his superhero name would be and comes to the conclusion that he would be called Caped Baldy. Several chapters later, and he does end up getting called Caped Baldy. He doesn't really like that.
* BrilliantButLazy: Or in this case, unbelievable yet lazy. While skill wise and intellectually, Saitama isn't much higher than a regular person, his strength and abilities outrank the best of the best and if he wanted to, he could probably single-handedly hunt every mysterious being to the point of extinction. He's just way too lazy, bored, and laid back to even consider how his power and abilities could change the world.
* CallingYourAttacks: A more literal example as Saitama doesn't have named techniques. His [[ExactlyWhatItSaysOnTheTin "Consecutive Normal Punches"]] are [[RapidFireFisticuffs just a bunch of normal punches thrown in rapid succession]] and from what we've seen so far, his "Serious Series" is just him applying ''actual effort'' into a move.
* TheCape: Saitama is both an aversion and a straight send up of a classic superhero. He's often selfish and is only a hero because IJustWantToBeBadass. He's a bit of a BloodKnight at heart and he literally dreams of fighting something that can give him a challenge. His knowledge of the world he lives in is borderline nonexistent at times. However, he inspires devotion from the heroes around him for a reason. Genos, PersonOfMassDestruction and cliche android boy hero, regards Saitama as his teacher. He's the WorldsStrongestMan who lives in virtual obscurity, but doesn't use his absurd power for anything except being a hero. He doesn't care about the ranks as long as they don't inconvenience him, and he fought off monsters for years without realizing he wasn't getting credit for his work.
* CassandraTruth: When he first tells the secret to his success at becoming the strongest hero, those present don't believe him.
* CatchPhrase: He often introduces himself as "just a guy who's a hero for fun".
* CharacterDevelopment: Starts off as a PunchClockHero who only cares about [[BloodKnight the thrill of the fight]] and [[GloryHound the public's recognition]], but eventually grows into a genuinely heroic person who [[HeroWithBadPublicity makes himself unpopular]] so that other people can get the respect that they deserve.
* CharlesAtlasSuperpower: Played with. His training regimen isn't even that intense [[spoiler:(100 sit-ups and 100 squats aren't a big deal, and while running 10 km is more impressive it's still well within ordinary human limits)]]; his commitment to doing it every day is noteworthy, but when he tells people about it they react with incredulity that it could have made him so strong. Genos even notes it would be impossible for a normal human being to reach Saitama's level just by training.
* ClarkKentOutfit: While most of it is because of how he is drawn, Episode 5 shows that he is more muscular than he usually looks. Notably, he has a different build in Episode 2.
* CombatPragmatist: Saitama is all over this trope. He actively subverts TalkingIsAFreeAction, tends to use his ludicrous speed to get behind people before attacking, nearly always [[OneHitKill one shots]] his target, and will kill his opponent if he feels they're irredeemable. This is actaully part of the reason the public doesn't like him much as his pragmatism actually makes him boring compared to flashier heroes like Genos.
* ComicallyInvincibleHero: Played with and explored -- he almost had an existential crisis simply because he grew so strong he couldn't enjoy his hobbies anymore. By the way, [[Pantheon/HeroicArchetypes deified.]]
* CrouchingMoronHiddenBadass: While Saitama is NOT stupid, he is extremely lazy and bored with just about everything. Given that he is functionally indestructible (nothing has yet appeared strong enough to hurt him), this is understandable. Most of the time he barely pays attention or puts effort into anything which gives him the [[BrilliantButLazy APPEARANCE of being a moron.]] [[AwakeningTheSleepingGiant And then when someone like Boros destroys a city or the Sea King mocks the resolve of heroes...]]
* CurbStompBattle: He dishes them out regularly.
* CursedWithAwesome: He's [[SuperStrength insanely powerful]], [[SuperSpeed ridiculously fast]], and [[NighInvulnerable practically immune to damage]], to the point of shrugging off ''anything'' that is thrown at him and defeating ''anybody'' that he fights in, well, [[RunningGag one punch]]. This is exactly why he's so depressed about his superhero job, because there's literally no challenge for him no matter how strong and seemingly invincible his opponent is.
* DarkAndTroubledPast: Subverted example, as he doesn't care about his troubled life at all in the past.
* {{Deconstruction}}: Saitama deconstructs the BloodKnight type of hero that became so prevalent in the Shounen genre after Franchise/DragonBall, showing what might happen when such a character becomes bored with heroism because their main motivation was having exciting fights rather than doing the right thing.
* TheDreaded: Any sentient monster that becomes even somewhat conscious of Saitama's true strength will be ''absolutely terrified of him'', as shown early on with the ([[OrWasItADream real]]) Subterraneans, Ground Dragon, Armored Gorilla and Asura Rhino. Humans are generally less shaken. Even the virtually powerless and incredibly timid [[spoiler:King]] shows no real signs of fearing Saitama, since he never harms innocent people.
* 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 usual, Saitama does not have a hard time at all defeating them.]]
* 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. [[spoiler: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 there were no witnesses to see Saitama beat the monsters. 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.
* DullEyesOfUnhappiness: Almost always seen with a blank expression on his face due to extreme boredom and lack of passion, since he's so powerful that almost no one is strong enough to give him a proper challenge.
* EmbarrassingNickname: He's not pleased to know that the Hero Association gave him the hero name "Caped Baldy".
* EmpoweredBadassNormal: "Road to Hero" depicts Saitama being a hero while in the midst of training; while he's nowhere as strong as he is now, he still has far superior strength and reflexes compared to the average human, to the point where he can knock out most of his opponents in a single punch to the face. Key word being ''knock out''; he had yet to gain the power to pulverize his targets into split atoms.
* EnlightenmentSuperpowers: One reading of how Saitama got his godlike abilities, given the very Buddhist connotations of his baldness, training regimen, and his unwavering commitment to being a hero solely for the sake of being a hero.
* {{Expy}}: FlyingBrick powers? Check. Tights and cape? Check. The most powerful, unbeatable hero in the world? Check. Superhero who is a superhero because he just wants to do good? [[Franchise/{{Superman}} Check and check]]. Down to his jumping, since Superman in his early days didn't fly, but "just" jumped very high.
* FingerTenting: When he contemplates his lack of fame as a hero.
* FlashStep: Even the fastest beings in the story going at full speed are terrified when he casually outpaces them. Took this UpToEleven during his third encounter with Sonic through another of his "[[LetsGetDangerous Serious Series]]", called "Serious Consecutive Side Hops".
* FlyingBrick: Short of actual flight (he gets around that by jumping when he needs to), his only powers are that he's both preposterously strong and fast.
* FoodAsBribe: Was bribed by Bang to eat at his dojo in hopes that he would learn some martial arts.
* FriendToAllChildren: He's shown giving a child lost in the mountains a ride home at one point, and his first heroic act was saving a child's life.
* FriendlessBackground: Before Genos came along, he's shown to not have any friends, not hang out with anyone, and have no desire to befriend others, even when he still was in school. He would spend most of his time training to become stronger, going out shopping, watching the news, or fighting monsters. However, as the series progress, he eventually makes new friends, though he views them as acquaintances.
* FromNobodyToNightmare: A heroic example. Once upon a time, Saitama was a recently-fired salaryman looking for work, until an encounter with a boy with a big chin and a crab monster changed his life. After [[TrainingFromHell three grueling years of training]], he became so powerful that he could defeat any foe with a single punch.
* FunTShirt: His infamous Oppai shirt.
* GoodIsDumb: Played with and subverted. While not the intellectual type (he horribly failed the written portion of the hero exam) he's actually quite insightful and perceptive.
* GoodIsNotSoft: While Saitama isn't ComicBook/{{the Punisher}}, and doesn't just go around killing bad guys, he has no problem turning sentient feeling creatures (albeit monsters) into piles of meat, bones, and gore. He also doesn't even give it a second thought after turning said creatures into piles of blood and offal. That said, he rarely ever goes for the kill right off and tends to give bad guys the chance to turn themselves in or run. If the bad guys turn out to be real [[JerkWithAHeartOfJerk jerkasses,]] [[ThisIsUnforgivable however...]]
* TheGreatestStoryNeverTold: Bordering on PerceptionFilter; most literally can't seem to see the things he does. Doctor Genus believes this is the true price Saitama paid for his vast power. It also helps that [[spoiler:King was erroneously given the credit for the sole reason of being the only other person present in those fights]].
* GroinAttack:
** Accidentally does this to Sonic at one point (Saitama just held out his fist, but Sonic's momentum carried him too far forward). Luckily for Sonic, he'd wanted to stop right before making contact instead of actually hitting him, otherwise Sonic would likely be nothing more than a red mess on a tree at this point.
** Accidentally does it to Sonic again in a special chapter, this time elbowing him in the groin (Sonic was trying to attack him from behind).
* 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.
** Thankfully this is mostly subverted 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 his physical exam.
* HeroismWontPayTheBills: He does receive 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. And despite Genos moving in with him and paying his rent his standard of living hasn't changed all that much.
* HeterosexualLifePartners: With Genos. He's not exactly thrilled by Genos following him around at first, but eventually warms up to him. It's helped by Genos paying part of the rent.
* HiddenDepths:
** Saitama originally comes across as a BrilliantButLazy type of individual, bored with everything around him. During his fights with [[spoiler: Boros]] and [[spoiler: Blizzard]], however, Saitama proceeds to show that not only is he much smarter and well versed than he appears, he also has an exceptionally strong moral core.
** Saitama has ''techniques'' that utilize his ridiculous strength. He calls them his 'Serious Series' and you have to be a ''special'' kind of villain for him to stop simply punching you and fight a little smarter.
** He was once [[spoiler: punched so hard he crashed into the moon (as in his starting point was Earth), and then he ''jumped'' all the way back to Earth, ''and landed almost exactly at where he started from''.]] There's ImprobableAimingSkills, and then there's GTFO.
* HumbleHero: He doesn't seem to care much about notoriety, and goes as far as to deliberately undermine his own reputation in order to ensure that weaker heroes (who were taking more serious risks than him even if they weren't able to win) get the respect he feels they deserve.
* IAmNotLeftHanded: Saitama's "Serious Series" of moves, where he actually bothers to put some effort into his attacks. Most of the time, he's so lazy and disenchanted he's ''barely trying''.
* IAmNotShazam: The series is named "One-Punch Man," obviously attributing the feat to Saitama. In-universe, he's never been called that.
* ImprobableWeaponUser: He once [[EyeScream defeated]] a giant crab monster using only his neck tie.
* InASingleBound: Saitama can't fly, so he usually has to jump using his SuperStrength to get places. [[spoiler:And since he can easily jump off the Moon all the way back to Earth, it's good enough.]]
* 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 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 (even by real life standards) tough training regimen.
* InvincibleHero: Deconstructed. Saitama is completely aware of this trope applying to him and the series deals with him coming to terms with this, eventually treating his superheroism more as a hobby than as the standard motive of eradicating evil.
* JerkWithAHeartOfGold:
** 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.
* JerkassFacade: He does not care too much about getting recognition for his deeds, since he does not really put a lot of effort into what he does anyways. But he does want other heroes, those who do risk their lives to save innocents, to be respected. And to achieve that, he will sometimes paint himself in a bad light for them to look better.
* KilledMidSentence: Not him, but most of his opponents are in the middle of introducing themselves and gloating about their awesome powers before Saitama punches their heads off.
* KirkSummation: To Blizzard:
--> '''Saitama''': 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!
* LastNameBasis: "Saitama" is his last name. His first name has yet to be revealed.
* LetsGetDangerous: Anytime he decides to pull out his Serious Series, which is where he puts in some actual effort into his moves.
** To a lesser extent any time he is drawn with the same level of detail as everyone else.
* LightningBruiser: Strong enough to kill most adversaries with one punch, faster than other heroes renowned for their high movement speed and he has yet to receive a single battle wound, even after taking some really heavy hits ([[spoiler:like getting ''kicked so hard he flew all the way to the moon'']]).
* LimitedWardrobe: He seems to have only a few sets of clothing, if you exclude the special chapters. There's also his iconic hero outfit, of which he apparently made himself.
* 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.
* LonelyAtTheTop: It's implied at different points that one of the prices for his power other than NoChallengeEqualsNoSatisfaction is that Saitama feels fundamentally isolated from basically everyone else as it's been so long since he had to struggle or feel challenged by anything he finds it difficult to relate to other people.
* MegatonPunch: Saitama often pulls these off when he's ''holding back more than ever'' to avoid killing a person. It's either smacking them to the ground so hard they leave their grin imprinted in the concrete, sending them flying into the sky, two with one punch, or simply sending them halfway through town. Again, this is when he holds back a lot. Any less and RealityEnsues in a rain of LudicrousGibs.
* 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, she berates him for getting rid of her sole source of income, and proceeds to kick him out anyways.
* NighInvulnerable: His training didn't just make him insanely strong, it also gifted him with incredible endurance, so much so that hitting him can actually harm his opponent.
* NightmareFace:
** Played for laughs when Saitama catches up to a mole-like enemy by punching into his tunnels, bursting out of the wall with a [[SlasherSmile horrific smile.]]
** Played straight later, while fighting Asura Rhino. As Asura attempts to attack him from behind, we get [[http://onepunchman.wikia.com/wiki/File:Saitama%27s_intimidation.png this shot of Saitama]] looking positively ''pissed'', and Asura Rhino jumps back in terror.
** During his first encounter with Sonic he moves his face so fast it blurs giving an incredibly unsettling effect
** During a later encounter with Sonic, Saitama bites Sonic's katana blade into pieces while Sonic is attacking with it. His face mid-chomp is very demonic-looking and unsettling.
* NoChallengeEqualsNoSatisfaction: Implied to be the real price for his unbeatable power. Being too strong robs the excitement of uncertainty and satisfaction from effort for any task (especially killing monsters and saving people).
* NonchalantDodge: [[SuperToughness Not that he needs to dodge]], but it does illustrate just how much faster he is compared to his opponents when they go all out with an attack and he sidesteps them as if by accident.
* TheNondescript: His baldness is the only strange thing about him, and even that just makes him look more like a cartoon stick figure.
* NonStandardCharacterDesign: While many characters in the series are subject to this, Saitama is remarkable in how ''unremarkable'' his appearance is, being distinct not from having particular facial features but from how simplistic his face is. His baldness just adds to the simplicity even further. See the series page image for a perfect example of how he stands out.
* NoSell: Being essentially invincible, he regularly tanks incredibly powerful attacks without flinching. In extreme cases, he doesn't even realize he's ''being'' attacked.
* NoSenseOfDirection: Despite his speed, he gets lost fairly easily, which is why he tends to be the last person to make it to a fight.
* OneHitKill: His specialty, as he can defeat ''literally anyone'' in with one punch. [[BlessedWithSuck Not that he's very happy about it.]]
* OneManArmy: Considering he almost single-handedly wiped out an alien invasion force AND beat their much more powerful leader with strength to spare, it's safe to say he's this.
* OOCIsSeriousBusiness: If Saitama gets angry then he's come across a ''truly'' despicable villain.
** In a more meta sense if the artist/animators bother to put in the effort with how much detail he's drawn with, it means he's more than a little worked up.
* OutsideContextHero: While the WorldOfBadass the series takes place in is no stranger to tough guys in costumes fighting giant monsters, Saitama is something different because of just how ''easy'' every single fight is for him.
* 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 also invokes this intentionally to himself, as he's 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.
* PersonOfMassDestruction: His "barely trying" punches turns monsters into LudicrousGibs and can leave massive holes in buildings, while his strongest seen punch split a planet-ruining KamehameHadouken, killed the one who fired it, and ''left a miles-wide split in the cloud cover of the planet until it reached the horizon''.
* PreAsskickingOneLiner: The two words you don't want to hear from him are [[LetsGetDangerous "Serious Series"]]. It means he is going to unleash a multi-megaton can of whoopass and turn your arrogant ass into paste.
* RapidFireFisticuffs: [[CallingYourAttacks "Consecutive Normal Punches"]]. [[ThereIsNoKillLikeOverkill And considering just one punch can kill pretty much anything...]]
* TheReasonYouSuckSpeech: He gives one to a whole ''city'' when the residents complain about his method of stopping the meteor that was going to hit the town. Never mind that he saved their city from total annihilation, the citizens started blaming him for the destruction. He wasn't happy about it.
* RequiredSecondaryPowers: He possesses ''ridiculous'' control over his own power. He can punch any adversary just hard enough to either kill or incapacitate them instantly, obliterated a mountain range while leaving Genos unharmed at the end of their sparring match (when his fist had stopped right in front of Genos' face, no less), and can control his strength to the point where he can do everyday tasks without issue... mostly. He did break one of the buttons on King's handheld console, after all.
* {{Salaryman}}: Was interviewing to be one, before he ran into Crabante and took up being a part-time superhero instead.
* SecretKeeper: He's fully aware of [[spoiler:King's true strength (or lack thereof)]]. However Saitama's so blasé that he doesn't bother telling anybody.
* SeeminglyProfoundFool: While Saitama does have plenty of genuinely wise views, at times Genos will read too much into the more innocuous things he says, slipping into this trope. It doesn't help that it's hard to tell whether he's doing it on purpose.
* ShounenHair: Before he went bald from training.
* SimpleMindedWisdom: Saitama is chock full of this. He's a very humble and down to earth kind of guy and often points out how complicated other people tend to make a situation. While he might not be the best intellectually speaking (he only just passed the hero exam due to his terrible written section), he's got the emotional IQ of Stephen goddamned Hawking.
* SkewedPriorities: Due to having overpowered strength, he doesn't really care for things like beating up monsters, only focusing on mundane things like supermarket sales. A good example of this is in Carnage Kabuto's fight, where he panics when he realizes that he missed the special Saturday sale.
* StealthMentor: Played with. Saitama never really intended on teaching Genos anything when Genos convinced Saitama to take him on as a student. Once he had revealed his training regimen to Genos, Saitama felt that he had nothing more to teach him. Genos still arduously tried to learn all he could from Saitama, even after learning this fact, and it paid off in the end. Being with Saitama has taught Genos a lot about selflessness and humility. Before he was only out for revenge, hence why he never registered with the Heroes Association, but now he also wants to protect people.
* StoryBreakerPower: A DeconstructiveParody. Saitama's life has become incredibly boring from winning all fights easily, but it's PlayedForLaughs.
* StylisticSuck: Saitama's model has a lot less detail than most other characters, almost as if he were drawn by a child. It's also the only way he stands out when he's on a manga cover and surrounded by larger, more well-drawn characters.
* SuperpowerLottery: He's just about the biggest winner in the setting, with SuperStrength so ridiculous he can OneHitKill literally anything, SuperSpeed that allows him to casually outpace even the fastest characters and [[NonchalantDodge avoid their attacks as if by accident]], and being so NighInvulnerable that [[NoSell he doesn't even feel an opponent's attack]]. The only drawbacks were the loss of his hair and 3 years of a simple (albeit arduous by reality's standards) training regimen to get there.
* SuperReflexes: He can casually keep up with Sonic's SuperSpeed, sidestep Genos' blasts during their sparring session, and even parry Lightspeed Flash's attacks (which, if said hero's name can be believed, should be physically impossible).
* SuperSenses: 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).
* SuperSpeed: He can casually dodge attacks faster than the speed of sound and can create nigh-infinite amount of afterimages with "Serious Consecutive Sidehops". And considering he can [[spoiler:jump from the Moon all the way back to Earth, which is about 384,000,000 meters]] in less than one second, he is faster than ''light itself''.
* SuperStrength: With a single punch Saitama can level mountains, fell giant city destroying monsters, cut planet destroying energy blasts in two and stop an object traveling at ''escape velocity''. And that's not even at his ''full'' power, which we've only seen a fraction of.
* SuperToughness: Verging into NighInvulnerable. He's only ever taken damage in a dream. [[spoiler:Boros hit him so hard once it knocked him to the surface of the moon; Saitama wasn't noticeably injured by the blow, the impact on the moon, exposure to vacuum, atmospheric reentry, or his impact on Earth.]]
** [[spoiler:The moon on the other hand...]]
* 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 normal-colored eyes.
* ThouShallNotKill: Played with. Saitama has no qualms about killing monsters because the monsters that he usually faces are always ChaoticEvil, out to kill people, or have already killed people. When he faces ''human'' opponents, all he does is incapacitate them, even if said human opponent is out for his blood like Sonic. [[spoiler: Even if the opponent himself acts in a way that all other people would consider too irredeemable to let live, Saitama still spares said opponent, believing that he's still a human and can change if given a chance, like Garou.]]
* TrainingFromHell: Subverted. Saitama claims the secret to his power is "100 sit-ups, 100 push-ups, 100 squats, and a 10 kilometer run, every single day". While it can be grueling for the average person, it's still well within the limits of ordinary human endurance. And for a person whose super power is the OneHitKill, it's rather anticlimactic.
* {{Troll}}: He has a gift for it.
* UnskilledButStrong: He has no formal combat training, and doesn't need any, due to being stronger, faster and tougher than anyone else.
* UnusuallyUninterestingSight: You'd think someone wearing a bright jumpsuit and a cape would attract people's attention, but he is often ignored, something he complains about. Justified, since there is actually an association for heroes and there are many more people wearing garish costumes, although Saitama didn't know that until Genos pointed it out.
* WarriorTherapist: While it's unknown if Saitama has reached enlightenment or not and has become a buddha, he certainly has a way with words when it matters and he uses his strength and speed to leave his opponents speechless as he verbally beats them down. If he thinks they are a danger to others or irredeemable, [[WhyDontYouJustShootHim he just kills them.]] That or he's panicking because he forgot about a sale. That being said, he usually either does give enemies a chance to surrender or he doesn't attack until they attack him first.
* WhatMeasureIsANonHuman: Played brutally straight, almost to the point of parody. Saitama kills obviously-sentient non-human monsters (even ones whose inhumanity is physically slight, like a CuteMonsterGirl) without the slightest hint of remorse; but he refuses to kill humans ever. [[spoiler:This is particularly obvious in the Garou arc, where Saitama decides that Garou is human and won't allow the heroes to kill him.]] Part of this is that some monsters were never human in the first place. Those who were human typically went crazy due to a particular trauma or obsession and mutated; after the mutation, the monsters have lost all humanity and will slaughter and kill without rhyme or reason, so Saitama shows them no mercy. [[spoiler: One reason he refuses to see Garou as a monster is that Garou won't kill other humans.]]
* 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.
* WhenAllYouHaveIsAHammer: Big bad monster terrorizing the neighborhood? Punch it. Unstoppable meteor plunging from the sky about to destroy the city? Punch it. Planet-busting energy blast being fired from a dimension-conquering alien overlord coming straight for you? PUNCH. THAT. SHIT.
* WholeCostumeReference: His costume is a color-inverted version of that worn by another bald superhero, Franchise/{{Anpanman}} (switched the colors of the gloves/boots and body, white cape instead of black).
* WillfullyWeak: He may end all his fights in one punch, but he only ever uses enough strength to do that. When using his Serious Series moves, he can casually create shockwaves that cross an entire ocean, and this is a mere fraction of his true power. Were he to go all out, the destruction would be cataclysmic, if not apocalyptic. He has yet to actually go all out because nothing so far has ever come close to forcing him to fight seriously.
* WorfHadTheFlu: He was actually knocked off his feet by a monster on his 300th day in training. Turns out it was just a bad tooth, and [[CurbStompBattle when said tooth was removed...]]
* 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!
* WorldsStrongestMan: Saitama is, to put it lightly, leagues above some of the strongest beings in the known universe, and far beyond the threshold of the S-Rank heroes to the point of single-handedly outclassing them during Boros's invasion. Even then, that wasn't even a third of his actual strength. As Boros puts it:
--> '''Boros:''' You really are... way too strong.
* ZeroApprovalGambit: [[spoiler: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 continue to get funding and donations, 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 popularity.]]

[[folder:Genos]]
!Genos, "Demon Cyborg"
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/opm_genos.png]]
-->''"Incinerate!"''
->'''Voiced by:''' Creator/KaitoIshikawa
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.]]
-----
* TheAce: Intelligent, cool-looking, and incredibly powerful. He even becomes one of the top 17 heroes right off the bat. It's just that Saitama blows him out of the water in terms of raw strength, speed and invulnerability.
* {{Adorkable}}: He's way too serious about everything, especially when Saitama is involved.
* AlwaysSomeoneBetter: No matter how many times he upgrades his body, Saitama will still surpass him in strength. So he asks Saitama to be his teacher in hopes of getting stronger just like him.
* AnArmAndALeg: It's not a proper fight if Genos doesn't lose at least one limb.
* TheApprentice: Officially Saitama's after the two of them became professional heroes.
* AttackAttackAttack: He focuses more on offense, and is always the first one to engage an opponent. While he can be successful in subduing lesser enemies this way, his bad habit of letting his guard down and underestimating his opponent means stronger opponents tend to capitalize on his poor defense.
* AwesomeMcCoolName: Might be a pseudonym.
* AwesomenessByAnalysis: [[spoiler: How he defeats the G4 robot. He used the steam to disperse the laser, enabling him to get close enough to connect the finishing blow.]]
* BadassInDistress: As mentioned above, Genos usually loses his body parts, making him helpless until Saitama or any other hero comes to his rescue.
* {{Bishounen}}: A slightly more masculine version than most.
* BlackEyesOfCrazy: subverted, he's a good guy and one of the heroes
* BriefcaseBlaster: Genos has a briefcase that transforms into a pair of arms for him to use to fire powerful blasts of energy.
* BullyingADragon: Hurled insults at Tatsumaki after she began insulting Saitama after the alien invasion. Needless to say, it didn't go well for him, to the point that he corrected himself after he tried calling her a brat even though she wasn't anywhere near him.
* CallingYourAttacks: ''"INCINERATE!"''
* CharacterDevelopment: Downplayed. He started off as a cyborg bent on having revenge on the mad cyborg, to a much more 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 had a master and a goal set.
* TheComicallySerious: Most of the humor involving Genos is that he's dark and serious about everything (like paying rent and peeling potatoes) in contrast to Saitama's apathy and lightheartedness.
* {{Cyborg}}: Of the WeCanRebuildHim variety. It's not made clear how much, if any of him, is still organic. He seems to have a spine, and some muscle in the shoulder area, but beyond that...
* {{Determinator}}: He definitely qualifies. He will attack monsters without fear until his parts are destroyed. Even losing body parts doesn't stop him from fighting. To the point that he was christened as Demon Cyborg by the Hero Association as a nod to this trait.
* {{Deuteragonist}}: If Saitama's not in the spotlight it's usually him being the focus in the earlier chapters. [[AdaptationExpansion And he's got more screentime in the anime.]]
* DidYouGetANewHaircut: In addition to an exchange of parts, he also had his hair replaced with heat and shock proof fibres. [[BaldOfAwesome Saitama notices]].
* DistressedDude: Whenever he loses his limbs. He'll be at the [[MonsterOfTheWeek Villain of the week's]] mercy until someone will come and distract the monster from killing him.
* DoomedHometown: He explains that when he was a kid, a rogue cyborg destroyed his home town and everyone he knew, leaving him mortally wounded.
* EatingOptional: His body is mostly mechanical and has its own internal energy source, but he has the ability to taste and can convert any organic food into biofuel so he can still eat if he chooses to.
* {{Expy}}:
** Of ''[[Anime/NeoHumanCasshern Casshan]]'', the boy android. Also his backstory is very similar.
** His manga design seems to be a combination of various characters from Manga/{{Eyeshield 21}}, Murata's previous work.
* EvenTheGuysWantHim: Puri-Puri-Prisoner sees the meeting of the S-class heroes as a chance to get closer to Genos.
* FanOfUnderdog: He's Saitama's first and biggest fan.
* FatalFlaw: He has the habit of usually letting his guard down. Ultimately, this causes him to be instantly wrecked by whoever he's fighting. Genos acknowledges this himself.
* FunnyAfro: When Asura Rhino turns one of Genos' attacks back on him, it makes his hair into this. It stays that way for the rest of the arc.
* GlassCannon: He is powerful, as shown in some of his fights, can create powerful blasts that can destroy enemies and surroundings, and is fast enough to keep up with Sonic. Unfortunately his durability leaves something to be desired. Once his arms are destroyed his fighting prowess lowers considerably. Also, he usually fights enemies that are out of his league.
* GoodThingYouCanHeal: He was designed to be easily repairable, which means that he'll be back on his feet in no time.
* HandBlast: He has blasters [[PowerPalms on his palms]].
* HeroicBSOD: [[spoiler: Had a small one when he realized he was no match for the Dragon-level monsters in the Monster Association arc. He also begins to doubt himself after he thinks he's weak because he gave up his human body and relied on artificial enhancements alone.]]
* HeroWorshipper: He idolizes Saitama to the point that he feels the need to pay attention to everything he says in the belief that there is some sort of lesson to it and is willing to be his live-in maid.
* HeterosexualLifePartners: Forces the matter with Saitama by offering to pay him an exorbitant amount of money for rent, just so he can figure out how Saitama became so powerful.
* HorribleJudgeOfCharacter: Didn't realize that he was talking with a mob boss in the second OVA. He also believes Saitama to be much more wise and profound than he actually is.
* HotBlooded: Downplayed. He may look like a stoic person but he actually has an aggressive streak. Dr. Stench and Amai Mask remark on this trait.
* HunterOfHisOwnKind: Hates a mad cyborg that destroyed his hometown, and for revenge became a cyborg himself in order to find and destroy it. He doesn't really resent or deny this fact -- he just distinguishes himself as a "cyborg of justice" instead.
* HypercompetentSidekick: He's smarter, works harder and generally is more reliable than his teacher. The fact that he was admitted into S-class is a testament to his abilities while Saitama failed the written portion of the test. [[ArsonMurderandJaywalking Plus, he even does household chores!]]
* ImmuneToBullets: In the 2nd OVA, a mob boss and half a dozen henchmen unload their weapons at him. He doesn't so much as flinch.
* InnocentlyInsensitive: Usually comments on Saitama's hair problems, much to the latter's frustration. A good example is him telling Saitama that kombu doesn't help in making hair grow, thinking that he bought so many for that purpose.
* IOweYouMyLife: To Dr. Stench, who saved him after he was nearly killed by the cyborg that destroyed his home town and to Saitama, who saved him from Mosquito Girl.
* IronButtmonkey: Spends an awful lot of his on-screen time in multiple pieces, thanks to any given MonsterOfTheWeek.
* KillItWithFire: He is capable of creating a huge wall of fire thanks to his arm cannons. He also uses this to roast his enemies to ashes.
* TheLancer: To Saitama. As well as being his self-proclaimed sidekick, Genos is also everything Saitama is not; namely the serious, cool, good-looking kind of guy you'd expect a superhero to be.
* MadeOfIron: Literally. Aside from that, he's survived a major genocide in his hometown.
* MotorMouth: This is how he fits the entire length of his life story in one panel, and in the case of the anime, under four minutes. Thankfully this is the only time he did it.
* MrExposition: In contrast to Saitama's cluelessness within the Hero Association. He's usually the one explaining the inner workings of the association.
* MrFanservice: Having a cyborg body doesn't stop him becoming one thanks to his [[{{Bishonen}} bishonen face.]]
* MundaneUtility: Can blow-dry dishes using his hands, and one of his fingers can transform into a potato peeler.
* NoSocialSkills: In the second OVA, he's shown to be this. He didn't even realize that he was facing criminals, thinking they were following a procedure and would give him the keys of the apartment back after he talked. The Mob boss even lampshades it.
* NotSoDifferent: Realized that Amai Mask could have been him if it weren't for Saitama.
* NotSoStoic: During their fight with Carnage Kabuto, Genos expressed irritation and raised his voice at Saitama when he told him the secret of his strength.
* OverlyLongGag: His entire backstory, as rendered to Saitama. It's incredible how he manages to be so repetitive in terminology and motivations.
** In written form, it's a WallOfText.
** In the anime, it's a more proper form of this: The tone is shifted to serious for a very rapid descent into parody of a montage, as he tells his life story with emotional music in the background and the scene cutting from random background shots showing the passage of time to Saitama becoming increasingly exasperated.
* OvershadowedByAwesome: Zigzagged as he, Saitama and a few others know who's stronger between the two, but most people think that he is the stronger one and assume that Saitama is using someone else's (possibly Genos's) fame, particularly in the entrance exam when the examiner thinks Saitama is nothing to write home about but sees Genos as being pretty impressive.
* PerpetualFrowner: He's never seen cracking a grin on-screen.
* PersonOfMassDestruction: It's downplayed, since this is a gag comic and since he's overshadowed by Saitama, but his arm cannons are ''ridiculously'' powerful. Early on, he effortlessly blows up an area several city blocks in radius, and later he destroys the entire House of Evolution (aside from the underground lab) with one hit; during his fight with Saitama, he blows up entire mountains ''by accident'' when his attacks miss.
* RapidFireFisticuffs: His Machine Gun Blow.
* RealMenWearPink: Does the household chores for Saitama. Bonus points that he wears a pink apron. Murata really likes to draw him either with an apron or doing chores.
* RedBaron: Demon Cyborg.
* RocketPunch: Thrusters on his shoulders and elbows allow him to add more power to his attacks.
* RunningGag: By the end of every arc, Genos invariably ends up losing one or more limbs. He almost broke this trend during the Alien Mothership attack, where he was one of the few to to remain relatively unscathed by the end of the battle. [[BullyingADragon Then he called Tatsumaki a brat]], and she threw him into a wall. The anime made sure to continue the gag by having Saitama accidentally yank his arm off while trying to help him back out.
* SleevesAreForWimps: Always, to show off his robotic arms. Also justified, as sleeves would never survive his bigger attacks, so having them in the first place would be a waste.
* StalkerWithoutACrush: He stalked Saitama for 5 days trying to find the secret to his powers.
** Implied in an extra chapter. How else would he know that Saitama has been staring at a vending machine?
* TheStoic: Nothing fazes this guy, even if his body is wrecked by the monster of the week.
* SuperSpeed: He actually manages to keep up with Sonic when the two fight, though Sonic ultimately proved to be faster.
* TakingTheBullet: He takes a head-on globule of acid that melts through a good portion of his back in order to protect a little girl.
* TakingYouWithMe: When he's overwhelmed by Mosquito Girl, he attempts to detonate his core so she'll die along with him. He's saved from that when Saitama turns her into a bloody smear on his apartment building wall.
* TechnicolorEyes: Black sclera and gold irises.
* UndyingLoyalty: No matter the choices Saitama makes or how he acts, he will always be loyal to him and gets his back when he needs it and he's not afraid to stand up for him. After Saitama defeats the Sea King and puts up a JerkassFacade to ensure that the other heroes get recognition, he has this inner monologue.
-->'''Genos''': Master Saitama. Are you really okay with this? But if this is the path you choose to take, master, I will accept your choice without a word. However, once you've turned the masses against you will you even be able to work as a hero anymore? I can't help but worry about what's to yet to come. If Master Saitama should ever find himself completely cornered, if it should ever come to that, I will.
* WaveMotionGun: In episode 7 of the anime, he gets prototype arm attachments that let him fire a powerful incinerating blast, which he makes all the more stronger by [[CastFromHP attaching his core to his arm and drawing power directly from it]]. [[TheWorfBarrage It fails to stop the meteor he was using it against.]]
* WhyDontYouJustShootHim: Invoked, then subverted. Upon arriving at the base of operations for the House of Evolution, Genos immediately vaporizes it, much to Saitama's surprise. However, it turns out that most of the base is underground.
* TheWorfEffect: Despite being considered very powerful by a lot of characters he tends to be defeated quite easily by named villains.
* YankTheDogsChain: It looked as though he was actually going to manage to get through the Alien Invasion arc without getting worfed, only for him to call Tatsumaki a brat and get embeded in a wall. Saitama completes the running gag by accidentally ripping his arm when trying to pry him free.

! Saitama, "Caped Baldy"
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/opm_saitama.png]]
->''"Just a guy who's a hero for fun."''
->'''Voiced by:''' Creator/MakotoFurukawa
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 absurdly 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 a multi-millionaire, who was motivated to establish the Hero Association when he heard about the incident.
-----
* 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 so lazy that not [[UpToEleven 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.]]
* AndThenWhat: Achieved his IJustWantToBeBadass dream and became so {{badass}} that nothing posed a challenge to him anymore. Which turned out to be incredibly boring.
* AntiHero: Definitely a KnightInSourArmor. He has the power to completely change the world, but is ''way'' too lazy to do so. He's also quite cynical about the hero business (not that he's wrong about said business). However, without a doubt, he will do the right thing.
* ArtShift: Saitama is drawn as either a weird, stick figure, a slightly more detailed stick figure, or a fully drawn, highly detailed normal figure that matches the art of the other characters. It's all part of the joke that most of the time he does not look like the type of protagonist you'd see in a {{Shonen}} manga and his normally unassuming appearance belies his strength.
* BadassCape: Arguably the only thing his old tailor got right with his outfit.
* BadassNormal: He managed to defeat a crab monster with nothing but his shirt tie before he ever even started training.
* BadassTeacher: Not that he wanted to be one, but Genos considers him such. Saitama even comments that, despite [[IndyPloy making it up as he goes along]], Genos is eating out of the palm of his hand.
* BaldOfAwesome: In that his awesomeness is the reason he became bald in the first place.
* BatmanCanBreatheInSpace: {{Downplayed}} during his battle with [[AliensAreBastards Boros]]. [[spoiler:While he does seem to still need oxygen given how he takes the time to hold his breath and pinch his nose shut, Saitama suffers no other ill effects from being on the moon's surface after Boros kicks him there, even casually taking his time in figuring out how he was gonna get back]].
* BerserkButton: People commenting on his baldness tends to irk him. But a much grander button for him is heroes who act cowardly.
* BigBrotherMentor: Plays this role to Genos. Although Genos originally joined Saitama to learn the secret behind Saitama's strength, he instead learns compassion, humility and heroism. Saitama is a positive influence that is helping Genos transition from a vengeance-fueled {{Antihero}} into a [[TheCape true hero]].
* BigDamnHeroes: A reoccurring theme and pretty much how most story arcs end. Saitama is usually late and if other heroes are involved, they have probably already been beaten or are in trouble when he arrives. Biggest example is when he defeats the Sea King. As this series is a [[AffectionateParody deconstruction]] of the whole super-hero genre, this is probably intended. Besides, he isn't aware that he was behind the foundation of the Hero Association for saving the big-chinned person's boy from a monster crab.
* BloodKnight: Part of his depression about being so goddamn strong is that no opponent can give him a challenge anymore. Whenever he faces a seemingly strong opponent and defeats it in one punch, he laments that the opponent "kinda got his hopes up", examples being Asura Rhino and the Deep Sea King. He even had a dream that had him really enjoying the rush of fighting an opponent he thought was on equal footing.
* BookDumb: Saitama is not stupid, but he did so poorly on the written portion of the Hero Association entrance exam that he was placed in the lowest possible category of hero, despite his record-shattering performance during the physical portion. He scored a 100 on the physical, and a 42 on the book. Thus, he got a 71 (the cut-off was 70 points).
* BrickJoke: While talking with Genos before the training session, he wonders what his superhero name would be and comes to the conclusion that he would be called Caped Baldy. Several chapters later, and he does end up getting called Caped Baldy. He doesn't really like that.
* BrilliantButLazy: Or in this case, unbelievable yet lazy. While skill wise and intellectually, Saitama isn't much higher than a regular person, his strength and abilities outrank the best of the best and if he wanted to, he could probably single-handedly hunt every mysterious being to the point of extinction. He's just way too lazy, bored, and laid back to even consider how his power and abilities could change the world.
* CallingYourAttacks: A more literal example as Saitama doesn't have named techniques. His [[ExactlyWhatItSaysOnTheTin "Consecutive Normal Punches"]] are [[RapidFireFisticuffs just a bunch of normal punches thrown in rapid succession]] and from what we've seen so far, his "Serious Series" is just him applying ''actual effort'' into a move.
* TheCape: Saitama is both an aversion and a straight send up of a classic superhero. He's often selfish and is only a hero because IJustWantToBeBadass. He's a bit of a BloodKnight at heart and he literally dreams of fighting something that can give him a challenge. His knowledge of the world he lives in is borderline nonexistent at times. However, he inspires devotion from the heroes around him for a reason. Genos, PersonOfMassDestruction and cliche android boy hero, regards Saitama as his teacher. He's the WorldsStrongestMan who lives in virtual obscurity, but doesn't use his absurd power for anything except being a hero. He doesn't care about the ranks as long as they don't inconvenience him, and he fought off monsters for years without realizing he wasn't getting credit for his work.
* CassandraTruth: When he first tells the secret to his success at becoming the strongest hero, those present don't believe him.
* CatchPhrase: He often introduces himself as "just a guy who's a hero for fun".
* CharacterDevelopment: Starts off as a PunchClockHero who only cares about [[BloodKnight the thrill of the fight]] and [[GloryHound the public's recognition]], but eventually grows into a genuinely heroic person who [[HeroWithBadPublicity makes himself unpopular]] so that other people can get the respect that they deserve.
* CharlesAtlasSuperpower: Played with. His training regimen isn't even that intense [[spoiler:(100 sit-ups and 100 squats aren't a big deal, and while running 10 km is more impressive it's still well within ordinary human limits)]]; his commitment to doing it every day is noteworthy, but when he tells people about it they react with incredulity that it could have made him so strong. Genos even notes it would be impossible for a normal human being to reach Saitama's level just by training.
* ClarkKentOutfit: While most of it is because of how he is drawn, Episode 5 shows that he is more muscular than he usually looks. Notably, he has a different build in Episode 2.
* CombatPragmatist: Saitama is all over this trope. He actively subverts TalkingIsAFreeAction, tends to use his ludicrous speed to get behind people before attacking, nearly always [[OneHitKill one shots]] his target, and will kill his opponent if he feels they're irredeemable. This is actaully part of the reason the public doesn't like him much as his pragmatism actually makes him boring compared to flashier heroes like Genos.
* ComicallyInvincibleHero: Played with and explored -- he almost had an existential crisis simply because he grew so strong he couldn't enjoy his hobbies anymore. By the way, [[Pantheon/HeroicArchetypes deified.]]
* CrouchingMoronHiddenBadass: While Saitama is NOT stupid, he is extremely lazy and bored with just about everything. Given that he is functionally indestructible (nothing has yet appeared strong enough to hurt him), this is understandable. Most of the time he barely pays attention or puts effort into anything which gives him the [[BrilliantButLazy APPEARANCE of being a moron.]] [[AwakeningTheSleepingGiant And then when someone like Boros destroys a city or the Sea King mocks the resolve of heroes...]]
* CurbStompBattle: He dishes them out regularly.
* CursedWithAwesome: He's [[SuperStrength insanely powerful]], [[SuperSpeed ridiculously fast]], and [[NighInvulnerable practically immune to damage]], to the point of shrugging off ''anything'' that is thrown at him and defeating ''anybody'' that he fights in, well, [[RunningGag one punch]]. This is exactly why he's so depressed about his superhero job, because there's literally no challenge for him no matter how strong and seemingly invincible his opponent is.
* DarkAndTroubledPast: Subverted example, as he doesn't care about his troubled life at all in the past.
* {{Deconstruction}}: Saitama deconstructs the BloodKnight type of hero that became so prevalent in the Shounen genre after Franchise/DragonBall, showing what might happen when such a character becomes bored with heroism because their main motivation was having exciting fights rather than doing the right thing.
* TheDreaded: Any sentient monster that becomes even somewhat conscious of Saitama's true strength will be ''absolutely terrified of him'', as shown early on with the ([[OrWasItADream real]]) Subterraneans, Ground Dragon, Armored Gorilla and Asura Rhino. Humans are generally less shaken. Even the virtually powerless and incredibly timid [[spoiler:King]] shows no real signs of fearing Saitama, since he never harms innocent people.
* 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 usual, Saitama does not have a hard time at all defeating them.]]
* 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. [[spoiler: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 there were no witnesses to see Saitama beat the monsters. 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.
* DullEyesOfUnhappiness: Almost always seen with a blank expression on his face due to extreme boredom and lack of passion, since he's so powerful that almost no one is strong enough to give him a proper challenge.
* EmbarrassingNickname: He's not pleased to know that the Hero Association gave him the hero name "Caped Baldy".
* EmpoweredBadassNormal: "Road to Hero" depicts Saitama being a hero while in the midst of training; while he's nowhere as strong as he is now, he still has far superior strength and reflexes compared to the average human, to the point where he can knock out most of his opponents in a single punch to the face. Key word being ''knock out''; he had yet to gain the power to pulverize his targets into split atoms.
* EnlightenmentSuperpowers: One reading of how Saitama got his godlike abilities, given the very Buddhist connotations of his baldness, training regimen, and his unwavering commitment to being a hero solely for the sake of being a hero.
* {{Expy}}: FlyingBrick powers? Check. Tights and cape? Check. The most powerful, unbeatable hero in the world? Check. Superhero who is a superhero because he just wants to do good? [[Franchise/{{Superman}} Check and check]]. Down to his jumping, since Superman in his early days didn't fly, but "just" jumped very high.
* FingerTenting: When he contemplates his lack of fame as a hero.
* FlashStep: Even the fastest beings in the story going at full speed are terrified when he casually outpaces them. Took this UpToEleven during his third encounter with Sonic through another of his "[[LetsGetDangerous Serious Series]]", called "Serious Consecutive Side Hops".
* FlyingBrick: Short of actual flight (he gets around that by jumping when he needs to), his only powers are that he's both preposterously strong and fast.
* FoodAsBribe: Was bribed by Bang to eat at his dojo in hopes that he would learn some martial arts.
* FriendToAllChildren: He's shown giving a child lost in the mountains a ride home at one point, and his first heroic act was saving a child's life.
* FriendlessBackground: Before Genos came along, he's shown to not have any friends, not hang out with anyone, and have no desire to befriend others, even when he still was in school. He would spend most of his time training to become stronger, going out shopping, watching the news, or fighting monsters. However, as the series progress, he eventually makes new friends, though he views them as acquaintances.
* FromNobodyToNightmare: A heroic example. Once upon a time, Saitama was a recently-fired salaryman looking for work, until an encounter with a boy with a big chin and a crab monster changed his life. After [[TrainingFromHell three grueling years of training]], he became so powerful that he could defeat any foe with a single punch.
* FunTShirt: His infamous Oppai shirt.
* GoodIsDumb: Played with and subverted. While not the intellectual type (he horribly failed the written portion of the hero exam) he's actually quite insightful and perceptive.
* GoodIsNotSoft: While Saitama isn't ComicBook/{{the Punisher}}, and doesn't just go around killing bad guys, he has no problem turning sentient feeling creatures (albeit monsters) into piles of meat, bones, and gore. He also doesn't even give it a second thought after turning said creatures into piles of blood and offal. That said, he rarely ever goes for the kill right off and tends to give bad guys the chance to turn themselves in or run. If the bad guys turn out to be real [[JerkWithAHeartOfJerk jerkasses,]] [[ThisIsUnforgivable however...]]
* TheGreatestStoryNeverTold: Bordering on PerceptionFilter; most literally can't seem to see the things he does. Doctor Genus believes this is the true price Saitama paid for his vast power. It also helps that [[spoiler:King was erroneously given the credit for the sole reason of being the only other person present in those fights]].
* GroinAttack:
** Accidentally does this to Sonic at one point (Saitama just held out his fist, but Sonic's momentum carried him too far forward). Luckily for Sonic, he'd wanted to stop right before making contact instead of actually hitting him, otherwise Sonic would likely be nothing more than a red mess on a tree at this point.
** Accidentally does it to Sonic again in a special chapter, this time elbowing him in the groin (Sonic was trying to attack him from behind).
* 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.
** Thankfully this is mostly subverted 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 his physical exam.
* HeroismWontPayTheBills: He does receive 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. And despite Genos moving in with him and paying his rent his standard of living hasn't changed all that much.
* HeterosexualLifePartners: With Genos. He's not exactly thrilled by Genos following him around at first, but eventually warms up to him. It's helped by Genos paying part of the rent.
* HiddenDepths:
** Saitama originally comes across as a BrilliantButLazy type of individual, bored with everything around him. During his fights with [[spoiler: Boros]] and [[spoiler: Blizzard]], however, Saitama proceeds to show that not only is he much smarter and well versed than he appears, he also has an exceptionally strong moral core.
** Saitama has ''techniques'' that utilize his ridiculous strength. He calls them his 'Serious Series' and you have to be a ''special'' kind of villain for him to stop simply punching you and fight a little smarter.
** He was once [[spoiler: punched so hard he crashed into the moon (as in his starting point was Earth), and then he ''jumped'' all the way back to Earth, ''and landed almost exactly at where he started from''.]] There's ImprobableAimingSkills, and then there's GTFO.
* HumbleHero: He doesn't seem to care much about notoriety, and goes as far as to deliberately undermine his own reputation in order to ensure that weaker heroes (who were taking more serious risks than him even if they weren't able to win) get the respect he feels they deserve.
* IAmNotLeftHanded: Saitama's "Serious Series" of moves, where he actually bothers to put some effort into his attacks. Most of the time, he's so lazy and disenchanted he's ''barely trying''.
* IAmNotShazam: The series is named "One-Punch Man," obviously attributing the feat to Saitama. In-universe, he's never been called that.
* ImprobableWeaponUser: He once [[EyeScream defeated]] a giant crab monster using only his neck tie.
* InASingleBound: Saitama can't fly, so he usually has to jump using his SuperStrength to get places. [[spoiler:And since he can easily jump off the Moon all the way back to Earth, it's good enough.]]
* 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 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 (even by real life standards) tough training regimen.
* InvincibleHero: Deconstructed. Saitama is completely aware of this trope applying to him and the series deals with him coming to terms with this, eventually treating his superheroism more as a hobby than as the standard motive of eradicating evil.
* JerkWithAHeartOfGold:
** 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.
* JerkassFacade: He does not care too much about getting recognition for his deeds, since he does not really put a lot of effort into what he does anyways. But he does want other heroes, those who do risk their lives to save innocents, to be respected. And to achieve that, he will sometimes paint himself in a bad light for them to look better.
* KilledMidSentence: Not him, but most of his opponents are in the middle of introducing themselves and gloating about their awesome powers before Saitama punches their heads off.
* KirkSummation: To Blizzard:
--> '''Saitama''': 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!
* LastNameBasis: "Saitama" is his last name. His first name has yet to be revealed.
* LetsGetDangerous: Anytime he decides to pull out his Serious Series, which is where he puts in some actual effort into his moves.
** To a lesser extent any time he is drawn with the same level of detail as everyone else.
* LightningBruiser: Strong enough to kill most adversaries with one punch, faster than other heroes renowned for their high movement speed and he has yet to receive a single battle wound, even after taking some really heavy hits ([[spoiler:like getting ''kicked so hard he flew all the way to the moon'']]).
* LimitedWardrobe: He seems to have only a few sets of clothing, if you exclude the special chapters. There's also his iconic hero outfit, of which he apparently made himself.
* 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.
* LonelyAtTheTop: It's implied at different points that one of the prices for his power other than NoChallengeEqualsNoSatisfaction is that Saitama feels fundamentally isolated from basically everyone else as it's been so long since he had to struggle or feel challenged by anything he finds it difficult to relate to other people.
* MegatonPunch: Saitama often pulls these off when he's ''holding back more than ever'' to avoid killing a person. It's either smacking them to the ground so hard they leave their grin imprinted in the concrete, sending them flying into the sky, two with one punch, or simply sending them halfway through town. Again, this is when he holds back a lot. Any less and RealityEnsues in a rain of LudicrousGibs.
* 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, she berates him for getting rid of her sole source of income, and proceeds to kick him out anyways.
* NighInvulnerable: His training didn't just make him insanely strong, it also gifted him with incredible endurance, so much so that hitting him can actually harm his opponent.
* NightmareFace:
** Played for laughs when Saitama catches up to a mole-like enemy by punching into his tunnels, bursting out of the wall with a [[SlasherSmile horrific smile.]]
** Played straight later, while fighting Asura Rhino. As Asura attempts to attack him from behind, we get [[http://onepunchman.wikia.com/wiki/File:Saitama%27s_intimidation.png this shot of Saitama]] looking positively ''pissed'', and Asura Rhino jumps back in terror.
** During his first encounter with Sonic he moves his face so fast it blurs giving an incredibly unsettling effect
** During a later encounter with Sonic, Saitama bites Sonic's katana blade into pieces while Sonic is attacking with it. His face mid-chomp is very demonic-looking and unsettling.
* NoChallengeEqualsNoSatisfaction: Implied to be the real price for his unbeatable power. Being too strong robs the excitement of uncertainty and satisfaction from effort for any task (especially killing monsters and saving people).
* NonchalantDodge: [[SuperToughness Not that he needs to dodge]], but it does illustrate just how much faster he is compared to his opponents when they go all out with an attack and he sidesteps them as if by accident.
* TheNondescript: His baldness is the only strange thing about him, and even that just makes him look more like a cartoon stick figure.
* NonStandardCharacterDesign: While many characters in the series are subject to this, Saitama is remarkable in how ''unremarkable'' his appearance is, being distinct not from having particular facial features but from how simplistic his face is. His baldness just adds to the simplicity even further. See the series page image for a perfect example of how he stands out.
* NoSell: Being essentially invincible, he regularly tanks incredibly powerful attacks without flinching. In extreme cases, he doesn't even realize he's ''being'' attacked.
* NoSenseOfDirection: Despite his speed, he gets lost fairly easily, which is why he tends to be the last person to make it to a fight.
* OneHitKill: His specialty, as he can defeat ''literally anyone'' in with one punch. [[BlessedWithSuck Not that he's very happy about it.]]
* OneManArmy: Considering he almost single-handedly wiped out an alien invasion force AND beat their much more powerful leader with strength to spare, it's safe to say he's this.
* OOCIsSeriousBusiness: If Saitama gets angry then he's come across a ''truly'' despicable villain.
** In a more meta sense if the artist/animators bother to put in the effort with how much detail he's drawn with, it means he's more than a little worked up.
* OutsideContextHero: While the WorldOfBadass the series takes place in is no stranger to tough guys in costumes fighting giant monsters, Saitama is something different because of just how ''easy'' every single fight is for him.
* 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 also invokes this intentionally to himself, as he's 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.
* PersonOfMassDestruction: His "barely trying" punches turns monsters into LudicrousGibs and can leave massive holes in buildings, while his strongest seen punch split a planet-ruining KamehameHadouken, killed the one who fired it, and ''left a miles-wide split in the cloud cover of the planet until it reached the horizon''.
* PreAsskickingOneLiner: The two words you don't want to hear from him are [[LetsGetDangerous "Serious Series"]]. It means he is going to unleash a multi-megaton can of whoopass and turn your arrogant ass into paste.
* RapidFireFisticuffs: [[CallingYourAttacks "Consecutive Normal Punches"]]. [[ThereIsNoKillLikeOverkill And considering just one punch can kill pretty much anything...]]
* TheReasonYouSuckSpeech: He gives one to a whole ''city'' when the residents complain about his method of stopping the meteor that was going to hit the town. Never mind that he saved their city from total annihilation, the citizens started blaming him for the destruction. He wasn't happy about it.
* RequiredSecondaryPowers: He possesses ''ridiculous'' control over his own power. He can punch any adversary just hard enough to either kill or incapacitate them instantly, obliterated a mountain range while leaving Genos unharmed at the end of their sparring match (when his fist had stopped right in front of Genos' face, no less), and can control his strength to the point where he can do everyday tasks without issue... mostly. He did break one of the buttons on King's handheld console, after all.
* {{Salaryman}}: Was interviewing to be one, before he ran into Crabante and took up being a part-time superhero instead.
* SecretKeeper: He's fully aware of [[spoiler:King's true strength (or lack thereof)]]. However Saitama's so blasé that he doesn't bother telling anybody.
* SeeminglyProfoundFool: While Saitama does have plenty of genuinely wise views, at times Genos will read too much into the more innocuous things he says, slipping into this trope. It doesn't help that it's hard to tell whether he's doing it on purpose.
* ShounenHair: Before he went bald from training.
* SimpleMindedWisdom: Saitama is chock full of this. He's a very humble and down to earth kind of guy and often points out how complicated other people tend to make a situation. While he might not be the best intellectually speaking (he only just passed the hero exam due to his terrible written section), he's got the emotional IQ of Stephen goddamned Hawking.
* SkewedPriorities: Due to having overpowered strength, he doesn't really care for things like beating up monsters, only focusing on mundane things like supermarket sales. A good example of this is in Carnage Kabuto's fight, where he panics when he realizes that he missed the special Saturday sale.
* StealthMentor: Played with. Saitama never really intended on teaching Genos anything when Genos convinced Saitama to take him on as a student. Once he had revealed his training regimen to Genos, Saitama felt that he had nothing more to teach him. Genos still arduously tried to learn all he could from Saitama, even after learning this fact, and it paid off in the end. Being with Saitama has taught Genos a lot about selflessness and humility. Before he was only out for revenge, hence why he never registered with the Heroes Association, but now he also wants to protect people.
* StoryBreakerPower: A DeconstructiveParody. Saitama's life has become incredibly boring from winning all fights easily, but it's PlayedForLaughs.
* StylisticSuck: Saitama's model has a lot less detail than most other characters, almost as if he were drawn by a child. It's also the only way he stands out when he's on a manga cover and surrounded by larger, more well-drawn characters.
* SuperpowerLottery: He's just about the biggest winner in the setting, with SuperStrength so ridiculous he can OneHitKill literally anything, SuperSpeed that allows him to casually outpace even the fastest characters and [[NonchalantDodge avoid their attacks as if by accident]], and being so NighInvulnerable that [[NoSell he doesn't even feel an opponent's attack]]. The only drawbacks were the loss of his hair and 3 years of a simple (albeit arduous by reality's standards) training regimen to get there.
* SuperReflexes: He can casually keep up with Sonic's SuperSpeed, sidestep Genos' blasts during their sparring session, and even parry Lightspeed Flash's attacks (which, if said hero's name can be believed, should be physically impossible).
* SuperSenses: 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).
* SuperSpeed: He can casually dodge attacks faster than the speed of sound and can create nigh-infinite amount of afterimages with "Serious Consecutive Sidehops". And considering he can [[spoiler:jump from the Moon all the way back to Earth, which is about 384,000,000 meters]] in less than one second, he is faster than ''light itself''.
* SuperStrength: With a single punch Saitama can level mountains, fell giant city destroying monsters, cut planet destroying energy blasts in two and stop an object traveling at ''escape velocity''. And that's not even at his ''full'' power, which we've only seen a fraction of.
* SuperToughness: Verging into NighInvulnerable. He's only ever taken damage in a dream. [[spoiler:Boros hit him so hard once it knocked him to the surface of the moon; Saitama wasn't noticeably injured by the blow, the impact on the moon, exposure to vacuum, atmospheric reentry, or his impact on Earth.]]
** [[spoiler:The moon on the other hand...]]
* 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 normal-colored eyes.
* ThouShallNotKill: Played with. Saitama has no qualms about killing monsters because the monsters that he usually faces are always ChaoticEvil, out to kill people, or have already killed people. When he faces ''human'' opponents, all he does is incapacitate them, even if said human opponent is out for his blood like Sonic. [[spoiler: Even if the opponent himself acts in a way that all other people would consider too irredeemable to let live, Saitama still spares said opponent, believing that he's still a human and can change if given a chance, like Garou.]]
* TrainingFromHell: Subverted. Saitama claims the secret to his power is "100 sit-ups, 100 push-ups, 100 squats, and a 10 kilometer run, every single day". While it can be grueling for the average person, it's still well within the limits of ordinary human endurance. And for a person whose super power is the OneHitKill, it's rather anticlimactic.
* {{Troll}}: He has a gift for it.
* UnskilledButStrong: He has no formal combat training, and doesn't need any, due to being stronger, faster and tougher than anyone else.
* UnusuallyUninterestingSight: You'd think someone wearing a bright jumpsuit and a cape would attract people's attention, but he is often ignored, something he complains about. Justified, since there is actually an association for heroes and there are many more people wearing garish costumes, although Saitama didn't know that until Genos pointed it out.
* WarriorTherapist: While it's unknown if Saitama has reached enlightenment or not and has become a buddha, he certainly has a way with words when it matters and he uses his strength and speed to leave his opponents speechless as he verbally beats them down. If he thinks they are a danger to others or irredeemable, [[WhyDontYouJustShootHim he just kills them.]] That or he's panicking because he forgot about a sale. That being said, he usually either does give enemies a chance to surrender or he doesn't attack until they attack him first.
* WhatMeasureIsANonHuman: Played brutally straight, almost to the point of parody. Saitama kills obviously-sentient non-human monsters (even ones whose inhumanity is physically slight, like a CuteMonsterGirl) without the slightest hint of remorse; but he refuses to kill humans ever. [[spoiler:This is particularly obvious in the Garou arc, where Saitama decides that Garou is human and won't allow the heroes to kill him.]] Part of this is that some monsters were never human in the first place. Those who were human typically went crazy due to a particular trauma or obsession and mutated; after the mutation, the monsters have lost all humanity and will slaughter and kill without rhyme or reason, so Saitama shows them no mercy. [[spoiler: One reason he refuses to see Garou as a monster is that Garou won't kill other humans.]]
* 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.
* WhenAllYouHaveIsAHammer: Big bad monster terrorizing the neighborhood? Punch it. Unstoppable meteor plunging from the sky about to destroy the city? Punch it. Planet-busting energy blast being fired from a dimension-conquering alien overlord coming straight for you? PUNCH. THAT. SHIT.
* WholeCostumeReference: His costume is a color-inverted version of that worn by another bald superhero, Franchise/{{Anpanman}} (switched the colors of the gloves/boots and body, white cape instead of black).
* WillfullyWeak: He may end all his fights in one punch, but he only ever uses enough strength to do that. When using his Serious Series moves, he can casually create shockwaves that cross an entire ocean, and this is a mere fraction of his true power. Were he to go all out, the destruction would be cataclysmic, if not apocalyptic. He has yet to actually go all out because nothing so far has ever come close to forcing him to fight seriously.
* WorfHadTheFlu: He was actually knocked off his feet by a monster on his 300th day in training. Turns out it was just a bad tooth, and [[CurbStompBattle when said tooth was removed...]]
* 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!
* WorldsStrongestMan: Saitama is, to put it lightly, leagues above some of the strongest beings in the known universe, and far beyond the threshold of the S-Rank heroes to the point of single-handedly outclassing them during Boros's invasion. Even then, that wasn't even a third of his actual strength. As Boros puts it:
--> '''Boros:''' You really are... way too strong.
* ZeroApprovalGambit: [[spoiler: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 continue to get funding and donations, 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 popularity.]]

[[folder:Genos]]
!Genos, "Demon Cyborg"
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/opm_genos.png]]
-->''"Incinerate!"''
->'''Voiced by:''' Creator/KaitoIshikawa
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.]]
-----
* TheAce: Intelligent, cool-looking, and incredibly powerful. He even becomes one of the top 17 heroes right off the bat. It's just that Saitama blows him out of the water in terms of raw strength, speed and invulnerability.
* {{Adorkable}}: He's way too serious about everything, especially when Saitama is involved.
* AlwaysSomeoneBetter: No matter how many times he upgrades his body, Saitama will still surpass him in strength. So he asks Saitama to be his teacher in hopes of getting stronger just like him.
* AnArmAndALeg: It's not a proper fight if Genos doesn't lose at least one limb.
* TheApprentice: Officially Saitama's after the two of them became professional heroes.
* AttackAttackAttack: He focuses more on offense, and is always the first one to engage an opponent. While he can be successful in subduing lesser enemies this way, his bad habit of letting his guard down and underestimating his opponent means stronger opponents tend to capitalize on his poor defense.
* AwesomeMcCoolName: Might be a pseudonym.
* AwesomenessByAnalysis: [[spoiler: How he defeats the G4 robot. He used the steam to disperse the laser, enabling him to get close enough to connect the finishing blow.]]
* BadassInDistress: As mentioned above, Genos usually loses his body parts, making him helpless until Saitama or any other hero comes to his rescue.
* {{Bishounen}}: A slightly more masculine version than most.
* BlackEyesOfCrazy: subverted, he's a good guy and one of the heroes
* BriefcaseBlaster: Genos has a briefcase that transforms into a pair of arms for him to use to fire powerful blasts of energy.
* BullyingADragon: Hurled insults at Tatsumaki after she began insulting Saitama after the alien invasion. Needless to say, it didn't go well for him, to the point that he corrected himself after he tried calling her a brat even though she wasn't anywhere near him.
* CallingYourAttacks: ''"INCINERATE!"''
* CharacterDevelopment: Downplayed. He started off as a cyborg bent on having revenge on the mad cyborg, to a much more 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 had a master and a goal set.
* TheComicallySerious: Most of the humor involving Genos is that he's dark and serious about everything (like paying rent and peeling potatoes) in contrast to Saitama's apathy and lightheartedness.
* {{Cyborg}}: Of the WeCanRebuildHim variety. It's not made clear how much, if any of him, is still organic. He seems to have a spine, and some muscle in the shoulder area, but beyond that...
* {{Determinator}}: He definitely qualifies. He will attack monsters without fear until his parts are destroyed. Even losing body parts doesn't stop him from fighting. To the point that he was christened as Demon Cyborg by the Hero Association as a nod to this trait.
* {{Deuteragonist}}: If Saitama's not in the spotlight it's usually him being the focus in the earlier chapters. [[AdaptationExpansion And he's got more screentime in the anime.]]
* DidYouGetANewHaircut: In addition to an exchange of parts, he also had his hair replaced with heat and shock proof fibres. [[BaldOfAwesome Saitama notices]].
* DistressedDude: Whenever he loses his limbs. He'll be at the [[MonsterOfTheWeek Villain of the week's]] mercy until someone will come and distract the monster from killing him.
* DoomedHometown: He explains that when he was a kid, a rogue cyborg destroyed his home town and everyone he knew, leaving him mortally wounded.
* EatingOptional: His body is mostly mechanical and has its own internal energy source, but he has the ability to taste and can convert any organic food into biofuel so he can still eat if he chooses to.
* {{Expy}}:
** Of ''[[Anime/NeoHumanCasshern Casshan]]'', the boy android. Also his backstory is very similar.
** His manga design seems to be a combination of various characters from Manga/{{Eyeshield 21}}, Murata's previous work.
* EvenTheGuysWantHim: Puri-Puri-Prisoner sees the meeting of the S-class heroes as a chance to get closer to Genos.
* FanOfUnderdog: He's Saitama's first and biggest fan.
* FatalFlaw: He has the habit of usually letting his guard down. Ultimately, this causes him to be instantly wrecked by whoever he's fighting. Genos acknowledges this himself.
* FunnyAfro: When Asura Rhino turns one of Genos' attacks back on him, it makes his hair into this. It stays that way for the rest of the arc.
* GlassCannon: He is powerful, as shown in some of his fights, can create powerful blasts that can destroy enemies and surroundings, and is fast enough to keep up with Sonic. Unfortunately his durability leaves something to be desired. Once his arms are destroyed his fighting prowess lowers considerably. Also, he usually fights enemies that are out of his league.
* GoodThingYouCanHeal: He was designed to be easily repairable, which means that he'll be back on his feet in no time.
* HandBlast: He has blasters [[PowerPalms on his palms]].
* HeroicBSOD: [[spoiler: Had a small one when he realized he was no match for the Dragon-level monsters in the Monster Association arc. He also begins to doubt himself after he thinks he's weak because he gave up his human body and relied on artificial enhancements alone.]]
* HeroWorshipper: He idolizes Saitama to the point that he feels the need to pay attention to everything he says in the belief that there is some sort of lesson to it and is willing to be his live-in maid.
* HeterosexualLifePartners: Forces the matter with Saitama by offering to pay him an exorbitant amount of money for rent, just so he can figure out how Saitama became so powerful.
* HorribleJudgeOfCharacter: Didn't realize that he was talking with a mob boss in the second OVA. He also believes Saitama to be much more wise and profound than he actually is.
* HotBlooded: Downplayed. He may look like a stoic person but he actually has an aggressive streak. Dr. Stench and Amai Mask remark on this trait.
* HunterOfHisOwnKind: Hates a mad cyborg that destroyed his hometown, and for revenge became a cyborg himself in order to find and destroy it. He doesn't really resent or deny this fact -- he just distinguishes himself as a "cyborg of justice" instead.
* HypercompetentSidekick: He's smarter, works harder and generally is more reliable than his teacher. The fact that he was admitted into S-class is a testament to his abilities while Saitama failed the written portion of the test. [[ArsonMurderandJaywalking Plus, he even does household chores!]]
* ImmuneToBullets: In the 2nd OVA, a mob boss and half a dozen henchmen unload their weapons at him. He doesn't so much as flinch.
* InnocentlyInsensitive: Usually comments on Saitama's hair problems, much to the latter's frustration. A good example is him telling Saitama that kombu doesn't help in making hair grow, thinking that he bought so many for that purpose.
* IOweYouMyLife: To Dr. Stench, who saved him after he was nearly killed by the cyborg that destroyed his home town and to Saitama, who saved him from Mosquito Girl.
* IronButtmonkey: Spends an awful lot of his on-screen time in multiple pieces, thanks to any given MonsterOfTheWeek.
* KillItWithFire: He is capable of creating a huge wall of fire thanks to his arm cannons. He also uses this to roast his enemies to ashes.
* TheLancer: To Saitama. As well as being his self-proclaimed sidekick, Genos is also everything Saitama is not; namely the serious, cool, good-looking kind of guy you'd expect a superhero to be.
* MadeOfIron: Literally. Aside from that, he's survived a major genocide in his hometown.
* MotorMouth: This is how he fits the entire length of his life story in one panel, and in the case of the anime, under four minutes. Thankfully this is the only time he did it.
* MrExposition: In contrast to Saitama's cluelessness within the Hero Association. He's usually the one explaining the inner workings of the association.
* MrFanservice: Having a cyborg body doesn't stop him becoming one thanks to his [[{{Bishonen}} bishonen face.]]
* MundaneUtility: Can blow-dry dishes using his hands, and one of his fingers can transform into a potato peeler.
* NoSocialSkills: In the second OVA, he's shown to be this. He didn't even realize that he was facing criminals, thinking they were following a procedure and would give him the keys of the apartment back after he talked. The Mob boss even lampshades it.
* NotSoDifferent: Realized that Amai Mask could have been him if it weren't for Saitama.
* NotSoStoic: During their fight with Carnage Kabuto, Genos expressed irritation and raised his voice at Saitama when he told him the secret of his strength.
* OverlyLongGag: His entire backstory, as rendered to Saitama. It's incredible how he manages to be so repetitive in terminology and motivations.
** In written form, it's a WallOfText.
** In the anime, it's a more proper form of this: The tone is shifted to serious for a very rapid descent into parody of a montage, as he tells his life story with emotional music in the background and the scene cutting from random background shots showing the passage of time to Saitama becoming increasingly exasperated.
* OvershadowedByAwesome: Zigzagged as he, Saitama and a few others know who's stronger between the two, but most people think that he is the stronger one and assume that Saitama is using someone else's (possibly Genos's) fame, particularly in the entrance exam when the examiner thinks Saitama is nothing to write home about but sees Genos as being pretty impressive.
* PerpetualFrowner: He's never seen cracking a grin on-screen.
* PersonOfMassDestruction: It's downplayed, since this is a gag comic and since he's overshadowed by Saitama, but his arm cannons are ''ridiculously'' powerful. Early on, he effortlessly blows up an area several city blocks in radius, and later he destroys the entire House of Evolution (aside from the underground lab) with one hit; during his fight with Saitama, he blows up entire mountains ''by accident'' when his attacks miss.
* RapidFireFisticuffs: His Machine Gun Blow.
* RealMenWearPink: Does the household chores for Saitama. Bonus points that he wears a pink apron. Murata really likes to draw him either with an apron or doing chores.
* RedBaron: Demon Cyborg.
* RocketPunch: Thrusters on his shoulders and elbows allow him to add more power to his attacks.
* RunningGag: By the end of every arc, Genos invariably ends up losing one or more limbs. He almost broke this trend during the Alien Mothership attack, where he was one of the few to to remain relatively unscathed by the end of the battle. [[BullyingADragon Then he called Tatsumaki a brat]], and she threw him into a wall. The anime made sure to continue the gag by having Saitama accidentally yank his arm off while trying to help him back out.
* SleevesAreForWimps: Always, to show off his robotic arms. Also justified, as sleeves would never survive his bigger attacks, so having them in the first place would be a waste.
* StalkerWithoutACrush: He stalked Saitama for 5 days trying to find the secret to his powers.
** Implied in an extra chapter. How else would he know that Saitama has been staring at a vending machine?
* TheStoic: Nothing fazes this guy, even if his body is wrecked by the monster of the week.
* SuperSpeed: He actually manages to keep up with Sonic when the two fight, though Sonic ultimately proved to be faster.
* TakingTheBullet: He takes a head-on globule of acid that melts through a good portion of his back in order to protect a little girl.
* TakingYouWithMe: When he's overwhelmed by Mosquito Girl, he attempts to detonate his core so she'll die along with him. He's saved from that when Saitama turns her into a bloody smear on his apartment building wall.
* TechnicolorEyes: Black sclera and gold irises.
* UndyingLoyalty: No matter the choices Saitama makes or how he acts, he will always be loyal to him and gets his back when he needs it and he's not afraid to stand up for him. After Saitama defeats the Sea King and puts up a JerkassFacade to ensure that the other heroes get recognition, he has this inner monologue.
-->'''Genos''': Master Saitama. Are you really okay with this? But if this is the path you choose to take, master, I will accept your choice without a word. However, once you've turned the masses against you will you even be able to work as a hero anymore? I can't help but worry about what's to yet to come. If Master Saitama should ever find himself completely cornered, if it should ever come to that, I will.
* WaveMotionGun: In episode 7 of the anime, he gets prototype arm attachments that let him fire a powerful incinerating blast, which he makes all the more stronger by [[CastFromHP attaching his core to his arm and drawing power directly from it]]. [[TheWorfBarrage It fails to stop the meteor he was using it against.]]
* WhyDontYouJustShootHim: Invoked, then subverted. Upon arriving at the base of operations for the House of Evolution, Genos immediately vaporizes it, much to Saitama's surprise. However, it turns out that most of the base is underground.
* TheWorfEffect: Despite being considered very powerful by a lot of characters he tends to be defeated quite easily by named villains.
* YankTheDogsChain: It looked as though he was actually going to manage to get through the Alien Invasion arc without getting worfed, only for him to call Tatsumaki a brat and get embeded in a wall. Saitama completes the running gag by accidentally ripping his arm when trying to pry him free.
