Will the Saitama from One Punch Man Have you ever been defeated?
Since the hype of the first season of the anime and its manga, OPM has been gaining more and more fans.
Many theories arise around the protagonist regarding his strength, but everyone forgets that he cannot be compared to any manga or anime character, as he is a satire on the most famous characters.
Alert! Contains spoilers for the two released anime seasons and the manga as well.
And that must be one of the reasons why the animation has achieved a lot of success more the characters that are part of the OPM like Tatsumaki, Fubuki, Garou among others.

Origin of One Punch Man
The series One Punch Man started in 2009 with the webcomic created by the mangaka who uses the pseudonym One.
The lines/drawings made by One were not pretty, but even so, the story was very successful in its publications on its website.
Your inspiration for creating the main character was from the anime of Anpanman that has been on air in Japan since 1988 and is aimed at children.
In 2012, manga began to be published in partnership with another mangaka named Yusuke Murata, which captured even more public attention due to the quality of his drawings.
For those who are not yet familiar with Saitama (not to be confused with the Saitama province in Japan), he is the "main character" of the manga/anime One Punch Man who trained so hard that he became so strong that he defeats his opponents (usually monsters) with just one punch.
After enrolling in the Hero Association, he started at C-Class, but is currently at B-Class rank 7.
His daily training that made him extremely strong was:
- 100 push-ups;
- 100 sit-ups;
- 100 squats;
- 10 km run;
- Eat 3 good meals (sometimes I would only eat a banana for breakfast);
- Did not use the air conditioning, even though it was very hot;
This type of training, according to Saitama, was what made him strong, but as a result all of his hair fell out, leaving him completely bald.
Not only has he gone bald, but he's always bored because he can't find anyone who can measure up to him or take more than a punch from him.
Evidently we will never know the truth (only the One) of what is the source of its strength. As the entire OPM universe is satire, so we already have the answer to that question.
Anime
The popularity increased even more after the big Japanese animation studio Madhouse made the adaptation of the manga, producing in 2015 the first season of One Punch Man.
In 2019, in the second season produced by the studio J.C.Staff, the animation quality left many people disappointed, as it did not come close to the previous one.
However, the story managed to faithfully deliver the essence that is the universe of OPM, with its parodies of shounen anime and many funny moments.
Where to watch?
Unfortunately, we have few streaming services that make it available to watch the seasons released by OPM here in Brazil.
- One Punch Man season 1 has 12 episodes and 7 ROE;
- 2nd season has 12 episodes and 6 OVAS;
We can only watch the 1st and 2nd seasons on Netflix and also on Crunchyroll.
It was recently announced that there will be a 3rd season, but the date has not been disclosed yet.
Now let's get to the point and show 4 times that Saitama from One Punch Man was defeated.
Saitama vs Genos
Saitama on the outside may be invincible, but on the inside his organs are apparently normal like any other human being.
In episode 5 of season 1 of the anime, he sees an ment in the restaurant where he is and decides to challenge his disciple Genos (ジェノス), a cyborg, S class hero rank 14.
After Genos accepts the challenge to see who can eat the entire bucket of udon and win the prize, Saitama can't take it and gives up.

From what is shown in the episode, Genos could eat a lot more.
Saitama vs Bang
In OVA 5 (Bang, Who is Too Overbearing - 強引すぎるバング), which takes place after the events of episode 7 of season 1, Silver Fang (シルバーファング), also known as Bang, begins to observe Saitama and Genos.
In a first approach he invites the two to go to his dojo, but neither of them appears.
He doesn't give up and keeps watching them and makes the invitation again (after they lost the meat they bought in an accident) saying that his dojo has top quality meat, and the two end up accepting.
The dispute is nothing more than jokenpo and whoever loses needs to put on the helmet in time to protect themselves from a hammer blow (toy hammer).
Genos loses in the first round and then Saitama loses all the following rounds to Bang.

Getting more and more nervous behold, after several defeats Saitama puts scissors and Bang paper, with this "victory" he tries to take the hammer, but it slips from his hands giving Silver Fang time to dodge, predicting that a hammer would come with extreme force.
Saitama vs King
We've already seen that Saitama is not an ordinary hero like we see in other anime.
Its main features are:
- Live bored and unmotivated
- Doesn't have one of the best uniforms compared to other more popular heroes
- It's too simplistic and clunky
In episode 10 of the second season, this becomes evident when he is invited by the S rank hero class 7 King to play a video game at his house.
He always sticks to the one-button tactic and King realized he's not good with games. In a few commands he defeats Saitama in the fighting game.

Saitama vs Mosquito
Mosquito? Yes, amazingly Saitama with all his super strength, agility couldn't kill a mosquito that was bothering him while irrigating his plant.
This happens at the beginning of episode 2 of the first season, after trying to "eliminate" the mosquito, when he runs after it with some kind of insecticide and accidentally ends up swallowing it.
It doesn't make much sense that he can't kill a mosquito, but with a slap he eliminated Mosquito Girl. The universe of One Punch Man has these things that don't have a logical explanation.
So far we've seen some defeats he has suffered, even though it's not necessarily a battle.
On his journey to being the strongest hero he suffered a lot from his training as a child.
child Saitama
At the age of 12, a special chapter of the manga is shown which was the first monster he faced and caught a lot.
A characteristic that he has from that time until today is the bored/inexpressive face.
Gabi Xavier tells in more detail in the video below:
Curiosities
In the fight against Lord Boros, after taking a punch from Saitama he loses his protective armor, releasing his hidden power, and while describing this we saw that face that became famous on the internet as saitama ok.

In the original audio in Japanese he says "そうか" which means something like I understand/really and in the Brazilian dubbing he says "oh I see."
