One-Punch Man could never have been adapted into manga (and later into an anime) without gaining some online infamy...
Please add entries in the following format:
- The meme. [[labelnote:Explanation]]The explanation behind the meme, if necessary.[[/labelnote]] Explanation Like this.
- Further mutations and successor memes, if any.
- OK.Explanation Saitama's reply to Boros, after the latter loses his Power Limiter, has his badly drawn face with a speech bubble (See main pic.) Normally used as an unimpressed reply to other people or as a punchline.
- Genos is modern art.◊ Explanation Asura Rhino/Carnage Kabuto crushes Genos against a wall in an odd pose and Saitama calls it "modern art". The name of the chapter is even "Modern Art" after this!
- Related to the above, it became a running gag within the fandom on how Genos loses his limbs in almost all his fights. Explanation In the webcomic, he got damaged 7 times, extra chapters not included.
- The running meme. Explanation Saitama and Genos running to Dr. Genus's lab because neither can fly. Genos is running in a way that a certain ninja would.
- Their run to City J to confront the Deep Sea King is quickly catching up in popularity for similar reasons.
- Saitama's "...eh?" face. Explanation Saitama makes this one when he finds out that he'll be dropped from the Hero Registry if he's inactive for one week.
- Caillou Shippuden. Explanation Some have noted the resemblance Saitama has to a grown-up Caillou. With the premiere of the anime, the series has been affectionately called this by the fans.
- One popular meme for Caillou is to call the title character "a little bitch" or some variation of said insult, so now with the premier of OPM, jokes about Saitama being Caillou's badass older self have become rather popular.
- Saitama's face drawn on eggs◊ Explanation Someone had the idea of drawing Saitama's expression on eggs. Naturally this spread out and many followed suit. This puts the term "egghead" on a whole new level.
- "100 push-ups, 100 sit-ups, 100 squats, and 10km running... Every single day UNTIL YOUR HAIR FALLS OFF!!!" Explanation Saitama's personal Training from Hell, which most find severely underwhelming, considering his power.
- "(Shorten it to) 20 words or less!"Explanation This line went memetic after chapter 7, where Genos delivered his Wall of Text backstory within a single panel, leading an exasperated Saitama to yell this line. Now this is used as a reply to nearly all backstories or infodumps.
- Tumblr likes to associate Genos with him saying SENSEI! over the course of the anime adaptation, Genos has said Sensei 98 times.
- _____ of _____ Sonic Explanation Sonic's name is usually forgotten by Saitama whenever they met, calling him names like Joint of Bones Panic. People found creative ways of making fun of his ridiculous name.
- One _____ Man: Explanation replacing the word 'punch' with any verb became popular in certain forums, then spreading out to sites like Reddit and Tumblr to the point where it became a meme.
- ONE _____!!!: Explanation A variation of the above which started occasionally popping up after the anime began airing. It's based on the anime's OP, which begins with singer Masaaki Endoh screaming "ONE PUUUUUUUUUUUUUNCH!" in the hammiest and most hot-blooded way possible.
- Local man saves anime.◊ Explanation Just like Kill la Kill, people have been calling it the savior of anime.
- Saitama's Oppai Hoodie◊ has become quite memorable in the fandom, and it often crops up in fanart.
- Drawing Saitama's half-assed face on anything has also became a meme.
- The One Punch Man anime adaptation was for a while the highest-rated television series with at least 5000 reviews on IMDB, dethroning televised juggernauts like Breaking Bad or Game of Thrones. This fact by itself had become something of a meme and causes some controversy on the Internet. Since then, the rating of the series fell to 9.1 and it's now in 17th place (a significant plunge, but still impressive as it is still the highest-rated anime series on the list and the third highest-rated animated series in all).
- FOUND YOU!Explanation After almost letting a mole monster go, Saitama eventually scares it into submission by sticking his head underground, then making this face.
- Saitama's smiling face.◊ Explanation Saitama's reaction as Beefcake grieves over accidentally killing his brother. This is used as a reaction image in forums like Reddit.
- Saitama & Tatsumaki's meeting.◊Explanation Drawn in ONE's artstyle, making fun of how the two strongest people in the world are drawn. The meme inspired people to photoshop Tatsumaki with someone else. It's usually accompanied by Saitama's line 'What's with this sassy...lost child?'
- Sonic no longer has a dick/If Sonic wasn't female then, he is now. Explanation Some people actually mistook Sonic for a girl because of his bishounen appearance, but even after the reveal that he's actually male, people jokingly remarked that he's become a girl anyway after Saitama hit him with a Groin Attack.
- Alternately, One Nut Man.
- __________ is Blast! Explanation Due to the fact that the S-class rank 1 is shrouded in mystery, people have been speculating on who the mysterious Blast is. It reached the point where someone would just point out that a character is Blast and reason out why.
- Pictures of Saitama punching out characters from other series. Bonus points if it's a ridiculously powerful character like Superman or the Hulk.
- "I'm just a guy who's a villain for fun." Explanation A joke on Reddit asked which hero would be the most menacing if they did a Face–Heel Turn. People then realized how horrifying and hilarious an evil Saitama would be.
- Wow, these people need a hobby. Explanation Saitama's reaction to a rather nasty piece of hate-mail. In the anime, he said "Here's a guy with free time." This line is usually used against trolls.
- "I'm pussy????" Explanation Raspberry Chainsaw did a photo with figurines of Bruce Lee and Saitama, which was exploited for a lot of memes.
- Bruce Lee:... Saitama: Acaso yo...? (Did I by chance...?)Explanation In Mexico, Colombia and Argentina, the photo was first used for couple situations and then after arriving to Spain it was used for any situation; the format in Spanish-speaking countries was that Bruce Lee does a complaint and Saitama answers with an Armor-Piercing Question.
- King is really the strongest hero.Explanation While being completely powerless In-Universe, the fans disagree and state the opposite. It's because he unknowingly indeed has the greatest power...which is the ability to have Saitama near him whenever he is in danger.
- Showed this to ________, now he is _______.Explanation The anime's main theme, ~Seigi Shikkou~ is very catchy and uplifting, making it perfect for being a Theme Song Power Up. This template is used a lot for various before/after situations.
- Leg bands Explanation Suiryu wears arm bands around his upper arms to suppress his strength. When he gets serious, his muscles bulge so much that they break through the bands. Fans began joking about how he still hadn't gotten serious because he still had his leg bands on, even though he actually doesn't have any.
- Mike Wazowski.Explanation Many people on Reddit nicknamed Manako as Mike Wazowski before her name was revealed, due to her single eye and small stature.
- Farewell, special blade-testing monster Explanation Atomic Samurai suffers a complete Curb-Stomp Battle against Black Sperm because the monster's splitting ability makes him the worst matchup for a swordsman who can only cut up things. When Atomic Samurai gets bailed out by Tatsumaki, he says this fake badass one-liner in an attempt to save face and pretend he just didn't get his ass kicked. Fans immediately began applying variations of the line to other characters acting cocky right after they've just been stomped into the ground.
- "If we win, I'll sit on your face" Explanation Born from a photoshopped edit of chapter 147 of Genos being inspired into a Heroic Second Wind by a promise of face sitting by Tatsumaki. This meme has grown significantly over time and even been attached to the anime with multiple videos on youtube including a soundtrack and even voice acting
- What's my name? One Punch Man!Explanation The lyrics came from a rap song that was in ad for new mobile game, which gained it's following thanks to popular twitter post. Catchy lines and Dunkachinno vibes got So Bad, It's Good status for good reason.
- Sandbag Atomic SamuraiExplanation Atomic Samurai's loss against Black Sperm has turned him into a Memetic Loser in the fandom, not helped by the fact that even after the fact he is still incredibly arrogant. As such, fan art and manga edits showing him losing to all manner of different characters has cropped up.
