Warning: contains spoilers for One-Punch Man #168
The hit manga One-Punch Man revealed that even an over-powered protagonist like Saitama is afraid of something. Recent, dramatic developments in the series made Saitama a much more relatable and «serious» character, including that he is afraid of losing his humanity, and relied on one person only to avoid that.
Saitama is so strong that he has no real challenges, making him constantly bored and uninterested in what is going on around him, which is pretty unusual for a protagonist and makes One-Punch Man stand out as a manga. The digital manga remake of the original One-Punch Man webcomic, written by One with art by Yusuke Murata, has further developed the Saitama character beyond this original premise, especially in the most recent chapters. Saitama recently showed strong emotions for the first time, after witnessing the death of his best friend Genos, proving that he is more human than what he looked like, despite his unreal power.

Chapter #168 of One-Punch Man further proved that Saitama is not the emotionless automaton that he appears to be. When Garou laments having caused the death of the innocent boy Tareo, despite wanting to save him, Saitama rebuts that, rather than saving the kid, Garou was only clinging to him for support. The Hero Hunter realizes that this is exactly what Saitama was doing with Genos, symbolized by the fact that he is still holding on to his cyborg friend's core unit. Garou then thinks that "There is no way that a person with that kind of power can keep his right mind", and realizes that this is what Genos represented for Saitama.
