Whenever asked to describe One Punch Man, what usually comes to mind is its explosive action sequences, god-tier battles, and the effortlessly overpowered protagonist, Saitama. But beneath the chaotic narrative lies its humor. What sets this series apart from other shonen genre anime is how it satirizes the very genre it belongs to.
Saitama is an insanely powerful hero, yet he does not care about being famous. Moreover, his laid-back attitude toward being a hero and his deadpan reaction make his situation seem very absurd, which contributes to a unique brand of humor that fans adore. Whether he's casually destroying planets or zoning out during someone's tragic backstory, Saitama manages to turn even the most intense situation into a laugh-out-loud moment.
In this article, let us look into 10 such hilarious Saitama moments in One Punch Man that managed to make its viewers laugh out loud.
List of 10 hilarious Saitama moments in One Punch Man
1. Saitama mistakes Tatsumaki for a lost child

When Saitama mistook Tatsumaki for a lost child, it was the most unintentionally insulting and funny interaction between the two of them. He is so nonchalant that Saitama just took a look at her for a second and came to this absurd conclusion.
Tatsumaki is a petite but fiery S-Class Rank 2 hero, and he just genuinely did not recognize or acknowledge her. Additionally, his deadpan tone just infuriated further, and that added more humor to his scene in One Punch Man.
2. Saitama kicks Garou away for interrupting his chat with King

In one of the funniest displays of misplaced priorities, Saitama was casually chatting with King about how he does not feel anything because he is that powerful, and Garou showed up trying to attack King and withoughithout missing a beat, Saitama delivers a swift, effortless kick that sends Garou flying, completely unbothered by his opponent’s menace.
The absurdity of Saitama casually swatting away a top-tier threat just because he does not want to be interrupted makes this moment unforgettable and a peak moment in One Punch Man humor.
3. Saitama casually punches Speed-o'-Sound Sonic

It is during one of the earliest and funniest moments in One Punch Man, Saitama faces Speed-o'-Sound Sonic, a self-proclaimed rival ninja. Sonic performs his flashy speed-based attacks, expecting admiration or fear. Saitama lets him run around a little, but then he wants to end this fight with one punch.
It was aimed to stop him, but unfortunately, this punch landed between Sonic’s legs. Sonic, facing his crumpling defeat, is comedic gold. What makes it funnier is Saitama explaining that he did not mean to punch him at that spot.
4. Saitama struggles to keep his wig on during the tournament
Saitama enters the Super Fight Tournament disguised as “Charanko,” wearing a cheap wig to conceal his identity. While he defeats every opponent effortlessly, he constantly has to adjust his fake hair during combat.
What is hilarious about him in this is how, each time his wig goes flying off, Saitama needs to readjust it before he can continue his fight. He flicks enemies into the air with one hit, then calmly reaches up to pat his wig back in place.
5. Saitama loses all his hair due to his intense training regimen

One of the most iconic and unintentionally hilarious backstories in anime history is revealed when Saitama discloses his secret of becoming overpowered. Fans were expecting some intense secret routine, but instead, it is an incredibly monotonous, simple routine.
He did 100 push-ups, 100 sit-ups, 100 squats, and a 10 km run every single day. And because of this so-called intense workout, Saitama got powerful but lost his hair. Genos takes the story seriously, while viewers are left wondering if Saitama is just trolling.
6. Saitama randomly shows up in King’s apartment uninvited

We discover that Saitama has developed a quirky friendship with King, the so-called “Strongest Man on Earth”. King is terrified of actual battle, but Saitama enjoys visiting him, not to train, but to play video games.
Moreover, the first time he went to meet him, Saitama entered through his window. It is hilarious because King lived on the 22nd floor. Saitama was unfazed by the height, and that added more to the gag.
7. Bang desperately tries to recruit an unbothered Saitama

When the S-Class hero called Bang (Silver Fang) recognizes Saitama’s overwhelming strength, he tries to recruit him to his dojo multiple times in One Punch Man. Bang uses all his seniority and charisma to persuade him, assuming Saitama would be honored.
But Saitama could not be bothered with this request. Bang dramatically talks about martial discipline and duty, while Saitama is just not interested.
8. Saitama accidentally destroys Jupiter’s moon with a sneeze
This is one of the most over-the-top and hilarious moments that happened in One Punch Man. During his god-tier battle with Garou, Saitama lets out a sneeze on one of Jupiter’s moons.
The result of the sneeze was a full-blown planetary explosion. The idea that a human can sneeze and destroy a moon is so absurd, it loops back around to being brilliant.
9. Saitama zones out while Genos monologues about his tragic past

In One Punch Man, Genos wanted to passionately recount his tragic origin story to Saitama, hoping to inspire and bond with his master. But Saitama was completely overwhelmed by the information.
The scene is cut from Genos rambling about his past to Saitama thinking this is a long story and zoning out. The timing is comedic perfection. Genos remains completely earnest, unaware that his master has mentally checked out.
10. Saitama loses to an insect
One of the most underrated yet hilarious moments in One Punch Man is when Saitama, the man who can obliterate world-ending monsters with a single punch, finds himself utterly defeated by a common housefly. As the insect buzzes around his apartment, Saitama tries swatting it with increasing frustration. He punches, swats, and slaps with absurd speed and power, but the fly always escapes.
In conclusion, Saitama may be the strongest hero in anime, but he’s also one of the funniest. From mistaking powerful allies for children to destroying moons with a sneeze, each moment not only highlights Saitama’s ridiculous strength but also his unmatched ability to make fans laugh.
One Punch Man is a brilliantly written series that constantly makes the audience laugh, as it is a blend of parody, making it one of the most unique premises in the shonen genre.
