Despite King being viewed as one of the mightiest heroes in One Punch Man, he possesses no superpowers. Is this assertion accurate?
One Punch Man employs a clear hero classification system, akin to My Hero Academia's Pro-Heroes Association. The Hero Association evaluates heroes not solely based on strength but also on their contributions to society and monster eradication. Unlike My Hero Academia, these classifications utilize letters to categorize classes. Those in the S-Class are individuals with exceptional combat capabilities.

However, within the S-Class exists a hero whose position is attributed to Saitama's merits. He accomplishes nothing, lacking even super strength. Despite lacking combat skills, theoretically, King may possess the strength deserving of an S-Class rank.
King often inadvertently appears at the precise time and location of monster sightings. He doesn't actively seek them out but is somehow drawn to them. Of course, King doesn't engage in combat with the monsters; he merely happens to be present. This earns him recognition for monster extermination, enough to warrant an S-Class rank. This coincidence repeats to the point where many fans question if he's genuinely as useless as he seems.

It's highly probable that King possesses an unparalleled superpower: extreme luck. Consequently, he manages to appear just as Saitama defeats monsters. Through belief and fear, King has even managed to eliminate a monster through his anxiety-induced vibrations, known as the King’s Engine.
A quintessential example of King's luck is when he precisely employed his shouting technique just as Garo regained consciousness, defeating numerous high-ranking members of the Monster Association.

Currently, it seems that King cannot control his luck, although it continues to enhance his reputation. However, King's luck appears unrivaled - it may even grow more potent over time. In the latest developments, King has become more confident, trusting in himself and acting based on others' perceptions of him.
In reality, King lured Centichoro towards Saitama, enabling the bald hero to vanquish the monster. Additionally, King has been fortunate in unintentionally taking actions that lead people to mistakenly believe he played a significant role in countering the Monster Association's assault. Suppose King could control his luck; perhaps One Punch Man would become even more intriguing.
