Why is the blasting that didn't appear in 18 years in One Punch Superman still the first in S-class?

In the whole animation, blasting only appears in memories from beginning to end. As an S-class hero of the Heroes Association, he is also the first in the S-class. The real person has never appeared in the whole animation, and I don't know his real identity. But even so, blasting can still sit firmly on the throne of S-class. Why?

Personally, I think the blasting was Saitama.

What we know about blasting is that in our memory, the tornado was saved by blasting, much like when Saitama had hair. Personal Brain Supplement+Comprehensive Great God revealed by Teacher Murata. Blasting once fought with Great God, and they all lost in the end. In order to recover from the injury, he had to take a newly developed drug, change back to a young appearance and lose his memory. Blasting left many successors to deal with the geek before he lost his memory. One of them is the establishment of the Heroes Association and the selection of high-level candidates. Only a few of them know his identity.

The explosion of amnesia turned into Saitama, an unemployed youth. As a hero, he awakened his inner hero heart even more after the crab monster incident, so after three years of extreme training, he unexpectedly recovered his hidden strength with 100 push-ups, 100 sit-ups, 100 squats and 10 km running every day. For what Saitama did, the top leaders of the Heroes' Association knew that it was a memory loss due to blasting, but the hero's heart did not die out, and it still harmed the people. Saitama's true identity has not been announced.

This statement is not groundless. The Hero Club was founded three years ago, and the memory of the explosion has never been lost. Two years ago, the old centipede was badly injured by blasting. At this point, the memory of blasting has been lost. However, in the face of threats, some hidden forces in the body broke out unintentionally, so the old centipede may be seriously injured and there are no witnesses. Besides the top hero, the only weirdo who knows the identity of blasting is Elder Centipede. At that time, the king also told the centipede elder that the blasting was here, and before he could react, Saitama punched him to death. And this setting may imply that Saitama is blasting. Judging from the rescue of tornadoes by blasting 0/8 years ago, it is unreasonable for tornadoes to attack Saitama, but it is normal not to know him after more than ten years of changes and baldness.

The No.1 position of the S-class has been vacant, and blasting has not appeared in recent years. Even the fortune teller's prediction, the call of the Heroes' Association, and poros's invasion of the earth didn't force the blasting out, because it was far and near. Over the years, blasting has certainly killed many weirdos. Eighteen years ago, there was no organized attack on weirdos like this. The existence of blasting can be said to be the savior of mankind.

To sum up, blasting can sit on the first throne of S class all the year round. Blasting is the founder of Hero Club. He has been transformed by injury and turned into a bald man in a cloak. The credit of these two people is enough to sit on the throne of S-class.
