The answer is no; Saitama does not have a limit, as revealed by the One Punch Man manga series. Saitama stands out as the most powerful hero in the anime. He is able to defeat any opponent with just one punch, and his strength is unparalleled. The source of Saitama’s immense power is his ability to break through the limiter, the power system that rules the one-punch world.
In episode 3 of One Punch Man, Saitama showed his unwavering dedication to his rigorous training regimen. Despite the difficulties and challenges he faced, he never gave up and constantly pushed himself to the brink. Through his relentless effort, his body underwent a transformation, becoming stronger, faster, and more durable. As a result of this transformation, he broke through his limiter and achieved a level of strength that could not be measured. With this newfound power, he was now capable of defeating any opponent with just a single punch.

In chapter 15.1 of One Punch Man, a throwback to when Saitama still had hair faced yet another opportunity to test his limits. After battling Personification Of A Light Pull Cord, he was overpowered and badly beaten. Despite the intense pain he was feeling, Saitama determined that he needed to push past his limits. With a smile on his face, he got back up, proclaimed that he was all better, and then dealt a near-fatal blow to his opponent with just one punch.
The topic of Saitama’s hair loss has been a source of speculation among fans. It is believed that the loss of his hair may be a symbol of his limits being broken.

The Limiter Explained
The concept of a limiter is a theoretical barrier that restricts the physical growth of a being. This concept was first introduced in chapter 89 by the character Dr. Genus in the manga series. He explains that the limiter is used to describe how the main character, Saitama, obtained his unparalleled strength.
According to Dr. Genus’ theory, every being in the universe has a power limitation placed on them by God. This limitation serves to prevent beings from losing their purpose and becoming overpowered. In Saitama’s case, he broke through this limiter and became the most robust character in the series.
The idea of a limiter is an intriguing one, as it touches on the larger theme of the consequences of power and the purpose of life. By placing a limit on power, the concept of a limiter raises the question of what happens when a being surpasses their limitations and reaches their full potential.

Garou and Saitama’s Limiter
The battle between Saitama and the divine-empowered cosmic Garou serves as a vivid illustration of the distinction between breaking one’s limiter and truly being limitless. This chapter contributes to the ongoing discourse and speculation about Saitama’s actual power
A sudden boost in power is showcased, with Garou revealing Saitama’s ability to grow exponentially when faced with much more formidable opponents. In chapter 165, Garou believed that by copying Saitama’s techniques and breaking his limits, he would be able to defeat the hero. However, the reality was far from his expectations. Saitama’s rate of growth was so tremendous that he quickly surpassed Garou’s level of strength, leaving the villain in a state of shock and disbelief.
