After experiencing an upsurge of intense emotion, Saitama's rate of growth increase exponentially so that he rapidly outclassed
Third, Some people say Saitama has infinite power. That is not true as in the manga and the anime; it was said that Saitama has infinite potential, not infinite power, meaning he can grow infinitely strong as long as he trains.
By breaking his limiter, does Saitama get stronger every day without him and the others knowing? Yes. This was confirmed in Chapter 168.
- Saitama growing exponentially is consistent with the whole narrative in opm about him being limitless - Mathematically, the limit of an exponential graph is unbounded, which means it can grow indefinitely. - Saitama is stated to be able to always oneshot himself of the previous day.
He is immortal, so he must live forever... His power isn't all about his body, but he is rather healthy, considering he's still doing his workout, so i reckon somewhere above 100 years, considering he's as normal as everyone else when it comes to basic human things.
Immeasurable Strength: Saitama possesses an immeasurable amount strength and as a result is capable of destroying powerful monsters and villains with a single one punch (though this strength is not limited to punches).
Immense Durability: Boros was shown to be amazingly resilient, to the point of being the first opponent of Saitama to survive after being hit directly by his normal punch, despite having his full power sealed by his armor.
That being said, Saitama hasn't used his full power in any of the fights in One Punch Man. However, fans expect him to go all out at some point in the story and are eagerly waiting for the character or the entity that will push Saitama to his absolute limits.
Whether an enemy is as strong or even stronger than him when the fight begins, Saitama will surpass their level at some point. Saitama will never reach his maximum power because he does not have a maximum, he will just keep increasing his power infinitely, like he did in One Punch Man Chapter 168.
Gravity is about 1/5th as strong as Earth's on Io, so with a mass of 89.3 x 10^21 kg (half of Io canceling out the one-handedness), Saitama at the time could probably effortlessly lift 16 quintillion tons on Earth.
A leading fan theory regarding the source of Saitama and most characters' strengths is that they trained and dedicated themselves to an inhuman level. The result of their high-level dedication is supernormal strength that is unusual for a human. In fact, many heroes in One-Punch Man can be linked to this theory.
[ Still trying to do the math on how, the only thing to ever actually damage Saitama in the series is a cat scratching his face.
If we calculate this distance over time, Saitama speed comes up at 150 9236 miles per second, which is quite close to the speed of light. It's safe to assume that he merely jumped. with no charging up, which means he can be faster. In short, Saitama can travel at the speed of light.
Saitama was an ordinary person with no talent or potential but, through effort alone, removed his natural limits and achieved strength not measurable even by the genius Dr. Genus. However, his strength made him bald and left him with an overwhelming sense of alienation.
“Too much power becomes unbearable and overwhelms its host, turning it into a mindless, rampaging monster.” Therefore, any being surpassing said limits would be, by definition, a monster. Saitama has long since surpassed this so-called, God imposed Limiter.
Fans were led to believe that Saitama's strength was a plot device that made the protagonist simply "stronger than everyone else", but the latest chapter of the manga revealed that, in fact, Saitama can still improve and become even stronger, making him a completely different kind of character.
Goku has his transformations and innate Saiyan traits. On the other hand, Saitama has overwhelming raw strength that, so far, surpasses anything that Saiyans can do. This matchup is too close to decide with absolute certainty, but, in all likelihood, Saitama would claim victory.
If Saitama is able to block an attack that would canonically eradicate the surface with his air pressure alone like its a walk in the park, his full power would be too much for the earth.
In terms of powers, The One Above All's are limitless, so much so that they are beyond the scope of understanding. If Saitama were to punch him, the blow would not even phase him. In fact, the only way to even weaken One Above All is to cause some form of multiversal imbalance.
Going by the facts offered by the last chapter, it can be argued that Goku has fought against opponents with equal or more strength than Saitama's in Dragon Ball's history. So a single Serious Punch from the bald hero would not be enough to destroy him as of yet.
Goku is an extraterrestrial being who has to lose a fight in order to get stronger. Saitama is a man that can defeat any foe with a single punch. If the two of them were to face off in a one-on-one battle, Saitama would easily win.
According to Saitama, he became strong due to his rigorous workout routine. It consisted of 100 push-ups, 100 sit-ups, 100 squats and 10 kilometers of running. Saitama pushed himself and worked out everyday for about three years, which also led to hair loss.
Super Saiyan 3 Goku at full power has a battle power of 24,000,000,000, 2 billion above Kid Buu's level.
To sum things up, Saitama hasn't received a promotion to S-class as of chapter 164, but it is very likely for him to receive one after defeating a considerable amount of strong characters.
