One Punch Man is a renowned comic series featuring the main character, Saitama, an extraordinarily powerful hero capable of defeating any opponent with a single punch. The work started as a webcomic created by the author ONE in 2009 and was later adapted into a manga illustrated by Yusuke Murata in 2012. Upon its release, One Punch Man became a global sensation.
Despite Saitama’s overwhelming strength being a key aspect of the story, it isn’t fully acknowledged in the way he handles battles. However, the mystery surrounding his power is gradually being unveiled. Recent developments in the latest chapters show that the series no longer intends to conceal the secret of Saitama’s strength from the wider world.

In Chapter 183, Saitama returns home to change clothes after an exhausting battle against Tatsumaki. While at home, he encounters a group of A-Class heroes who come to approach him. It turns out they witnessed Saitama’s battle with the S-Class heroes in the hospital and are eager to build a relationship with the notoriously uninterested hero.
We also see Child Emperor—another S-Class hero—getting closer to uncovering Saitama’s secret. While rewatching footage of the battle at the Hero Association headquarters, he realizes there’s more to Saitama than meets the eye.

Up until now, not many people recognized the full extent of Saitama’s power, nor the achievements he has accumulated. However, more heroes are beginning to realize that Saitama is indeed the “dreadful” individual he is often portrayed to be. Dr. Bofoi (Metal Knight) was the first S-Class hero to discover Saitama’s secret by reviewing security footage from the battle.
Currently, Child Emperor is the second individual to unveil Saitama’s secret. As a result, the number of high-ranking heroes aware of Saitama’s true strength is steadily increasing, including characters like Mumen Rider, Fubuki and her team, King, and others.
Given these developments, it is clear that One Punch Man is building towards a revelation regarding Saitama’s immense power. Fans are keen to see whether this will alter Saitama’s position in the hero community or lead to further significant developments in the storyline of the series.
