One Punch Man-A Hero Nobody Knows, Just like in the anime and manga, Saitama can instantly KO any opponent with just one punch, and is invulnerable to any attack. As this would make for a one-sided fighting game, matches with Saitama employ a special mechanic.
If Saitama is selected for a player’s team, he will not immediately be playable. Instead, a timer will appear at the side of the screen, showing Saitama running to the scene of the fight. If the player can keep their remaining two fighters alive until the timer runs out, Saitama will appear and can be used to win the battle. (Unless the opponent also has Saitama on their team, in which case the two can only punch each other ineffectively until the match timer runs out) Performing combos and perfect counters will shorten the timer.
1. He does not take credit
In One Punch Man season 1 episode 9, after Saitama defeated the Deep Sea King, there is a civilian badmouthing Saitama. At first, the other civilians didn’t agree with the badmouthing civilian but then Saitama chose to claim that the monster is weak and he just took the bounty… But the monster is not even WEAK!
Q. Why would Saitama choose this path?
Saitama clearly likes getting credit and being appreciated. However, I believe the reason he did that in this particular situation, is because he cared more about how the civilians were viewing the other heroes and didn’t like the way they were belittled despite them putting their lives on the line. We sort of see this from Saitama, especially after Mumen Rider gets beaten up by Deep Sea King. Saitama clearly knew the former at least in terms of power, was practically useless. However, he is still appreciative and acknowledges the effort put in by Mumen Rider as you can see here.
Another important factor to note is that, unlike other professional heroes, Saitama doesn’t walk into a fight with anything at stake or anything to lose. He isn’t in a situation where his life is at risk or he’s doing something extremely difficult compared to the rest of the Heroes who are literally putting their lives on the line. We can see this side of him when he’s surprised that his ranking went up significantly after smashing the meteor which he didn’t consider as big of a deal
2. Sitama Power Source.
He did his hero training regiment every day for 3 years. This consisted of 100 push-ups, 100 sit-ups, 100 squats, and a 10 km run every day.
He would also eat 3 meals a day, and never use A/C or heat in the summer or winter to strengthen his mind.
Although the training regiment seems easy and simple, it was revealed that it was very intense for Saitama causing his body to ache, vomit blood, and nearly kill him. After training for 1 and a half years, Saitama went completely bald and achieved super strength. He then trained for another year and a half before becoming a hero for a hobby. It should be pointed out that Saitama wouldn’t take breaks in between workouts and he often fought Mysterious Beings that appeared during his training.
However, the underlying reason why Saitama become so strong was he removed his limiter. The limiter is the natural growth limit that every living being has that limits how strong they can become or how much they can grow. No matter how much effort one puts in, one can never surpass their limit. Saitama, on the other hand, put in so much effort that he somehow achieved the impossible and broke his limiter completely.
