Saitama's rank in the web comic is sort of unconventional. His strength is off the charts, making it difficult to slot him into a specific rank. You could say he's in a league of his own, far above the typical rankings.
Saitama in One Punch Superman was a very powerful hero, but the reason he couldn't become an S-class hero was because of some problems with his personality and motivation.
Saitama was a very self-centered person. She had a very strong pursuit of her own strength, even at the expense of the interests of others. This kind of self-seeking performance often made him do some selfish actions, such as attacking other heroes or ignoring the safety of others in order to protect himself.
Saitama's personality also caused him to be unclear about some moral values. He did not care about the feelings of the other heroes. He only cared about whether he could become stronger. This kind of attitude often caused problems in teamwork because he did not understand the importance of teamwork.
In summary, Saitama's personality and motives were the main reasons why he could not become an S-class hero.
