One-Punch Man/Characters

Saitama
The titular character, a hero who can defeat any threat with just ONE PUUUUUUUUUUUUUUUUUUUUUUUUUUUNCH!


 * Art Shift: His appearance can go from doodle to cartoon to anime-epic at any time.
 * Art Style Dissonance: The difference between his cartoony appearance and his serious one is clear, but it also helps demonstrate how serious or intense a situation is by how he looks.
 * Badass Abnormal: After 3 years of his "intense training regiment", he has become the most powerful being in the universe it seems.
 * Badass Creed: He has 2:
 * "I'm just a guy who's a hero for fun... and profit."
 * "If heroes run away, who's left to help."
 * Badass Normal: Even before he underwent his training regiment for 3 years, he managed to kill a monster crab guy with only a tie.
 * Badass Nickname: It's the title of the series.
 * Blatant Lies: He pulls these on Genos since Genos moved in as his disciple, but didn't believe him when he revealed the truth behind his incredible powers. At the same time though, he lies mostly because he otherwise can't think of anything else to tell him to do aside from his exercise routine, and even that wouldn't be much use to Genos since his body is mostly robotic.
 * Brilliant But Lazy: His powers could be used for SO much, but he lacks the motivation to bother.
 * Calling Your Attacks: All he does usually is punch someone, but occasionally he will do a move he calls "Consecutive Normal Punches." which is just him punching rapidly, OR in the rarest of cases, he does a punch from what he calls his "Serious Series".
 * Comically Invincible Hero: Hence the name.
 * Complete Monster: It's very funny and ironic to think that the monsters of the world that do battle with him, consider him this. It got to where he lives in an area of City Z alone with nobody else, be they person OR monster that is willing to live nearby him, with the exception of Genos.
 * Covert Pervert: You wouldn't know it by looking at him. Unless you read his favorite sweatshirt that has the word "Oppai" printed on it. He is also an anime otaku, AND he is once seen fantasizing about how he should have his own fan club filled with nothing but hot fan girls.
 * Danger Deadpan: According to him, he finds himself feeling less and less emotion due to how over-powered he has become.
 * Deadpan Snarker: He is SO extremely powerful that he is almost constantly bored. He's also defeated countless super powerful bad guys and monsters, so he acts like he's heard just about every evil villain speech you can think of before.
 * Destructive Saviour: In the third chapter of the webcomic, Saitama defeats a powerful giant with one punch, as always...but the falling body of the giant destroys B-ville.
 * Expy: With his powers, he's like a bald Chuck Norris!
 * Genre Savvy: He has been through a lot during his time as a hero, so he is very familiar with how his battles go. Villains cause trouble, he shows up, the villains boast or try to taunt him, he offers them a chance to stop or surrender, they refuse... Punch! The end.
 * Genre Blindness: It isn't until Genos actually informs him that he learns that there is an organization for super heroes to join that actually provides funding and recognition for heroic deeds.
 * Heroic Sacrifice: He practically DESTROYS his own hero reputation for the sake of other heroes and the organization as a whole's own reputation with the public.
 * Humble Hero: While the theme song suggests this is the case, Saitama did actively seek recognition. However when given the chance to receive credit for his actions, he threw it away so other heroes that risked their lives either to defeat a powerful foe or merely stall said foe from killing innocents till someone (or a group) who could defeat him arrived got recognition for their heroism.
 * Kryptonite Is Everywhere: Somewhat literally. The only thing close that he has to a weakness is that he has a poor sense of directions which leads him to showing up at the last second. Well that, and he's kind of lazy.
 * Made of Explodium: You'd think anything he punches is this when you consider how whoever or whatever he punches always gets obliterated by the punch. But nope, it's not what he punches... It's just that his punches are THAT strong.
 * Nice Guy: He doesn't do his heroic deeds for admiration or glory. He does it because he wants to, and he never passes up a chance to help someone in need... So long as he hears about it.
 * Nightmare Fuel: Anyone able to actually sense his power is terrified of him, except they also don't believe it when they see him, so they almost always underestimate him, which leads to them being punched.
 * [[Otaku]:] He lives alone in an apartment, and spends most of his time either fighting villains, lounging around watching TV, or reading manga all day. Till Genos shows up, and he drops the "living alone" part.
 * Reason You Suck Speech: He tends to just flatly tell his opponents to stop being evil or stop causing trouble. If they don't... They get PUNCHED! Some try delivering them TO him, but he tends to brush them off.
 * Spanner in the Works: His first act as a hero was what led him to training to obtain his seemingly infinite powers AND it also led to the founding of the Hero's Association . It also leads to numerous heroes taking credit for his deeds.
 * Too Awesome to Use: His powers seem to have no limit, and the things he does regularly demonstrate that. However, if he were to use the full extent of his powers haphazardly, the damage he could inflict could very well destroy the world and then some. THANK GOD, he seems to have extremely good control over it though, except that even if he holds back he still manages to stop any threat with a single punch.
 * What the Hell Are You?: His enemies and even his friends wonder how the hell he has his unstoppable power. If he's some sort of demon or deity or something.
 * What the Hell Hero: Some people try to paint him as a fraud who steals credit for heroic deeds from other heroes. He later pretends to do exactly that during the Deep Sea King incident, because he wanted to avoid the populous losing faith in the organization as a whole, and so that the other heroes who fought wouldn't have lost public favor as well.
 * When It All Began: His first heroic deed was saving a boy with a big chin from a giant crab monster, and that was before he got his powers. From then on, he began training to become a super hero, and eventually does! At the same time, his first heroic deed inspired the big chinned boy's father into founding the Hero's Association in the first place.
 * World of Cardboard Speech: He has probably delivered more of these than Superman. Except that he has expert control over his strength so he never seems to worry about it as far as hurting innocents or allies is concerned.
 * Worthy Opponent: Yes, there's nobody who has ACTUALLY been a threat to him personally, but he still compliments some of the foes he faces... Right before he obliterates them with a single punch. Such as Lord Boros who was the first opponent we've seen to get him to use a move from his "Serious Series" of punch moves.

GENOS
A cyborg who lost his family when a crazy cyborg massacred his home town. He later meets Saitama and becomes both his apprentice and roommate.


 * Ascended Fanboy: Of sorts, he was immediately in awe of Saitama's unlimited power, so he asked to become his apprentice, and eventually convinces Saitama to let him become his roommate. While living together, Genos is almost constantly taking everything Saitama says as though it were Gospel, and studies his actions as though it were some sort of secret badass training regiment.
 * Dark and Troubled Past: Played for Laughs. His entire back story isn't told by flashback but by simple lines of text inside the webcomic, losing any kind of emotional impact of a normal flash back but becoming comically annoying to read. And Saitama is angered by having to hear it.
 * Heroic Sacrifice: He pulls this at least twice.
 * Nice Guy: Initially he was just fighting bad guys to test his powers, but his time with Saitama has helped him become a better person and hero.
 * No Kill Like Overkill: When he spars with Saitama, he claims to be unleashing max output of his powers, and he wanted Saitama to do the same. Saitama then fakes him out and unleashes a single punch, but stops himself before touching Genos. The force of said punch obliterated the wall of the canyon they were standing in as well as parted some of the clouds in the sky. Leading Genos to realize he could never hope to reach the same amount of power Saitama has... No one could.
 * Oh Crap: His moments of this generally come from him being so impressed by Saitama's limitless powers.
 * Reason You Suck Speech: He tries to dish out one or two, but they tend to backfire.
 * Too Dumb To Live: Initially, he is very reckless when charging into combat. He usually underestimated his opponents or gets distracted which led to his defeat several times.
 * Unskilled but Strong: Has a lot of firepower and weapondry, but no fighting techniques aside straigth punches and kicks. He also gets caught off-guard often during battles.
 * What an Idiot!: Despite having some of the best weaponry and technology in the world comprising his body, he still has many instances where he underestimates his opponents and gets beaten because of it. He also tends to be so wrapped up in how powerful Saitama is, that he considers everything he says or does as though it were Gospel.
