User blog comment:Kuopiofi/Saitama - Absolute or Supernatural?/@comment-4714517-20160906191402/@comment-24053170-20160908001442

The opponents/monsters/villians in the series are ranked by disaster levels, most of the opponents saitama fights are barely mid way up the ladder in terms of destructive power.

In fact saitama has yet to face any opponent at the top of the scale.

In pratical terms he is the equivalent of a level 100 character fighting 10th level monsters.

So in actuality he really isn't all the strong, they say he is a user of absolute strength but its more like the opponents he fights aren't really all that impressive.

Basically if you look at the bigger picture of the series, nothing he has fought to date are anywhere near the level of opponents that most fictional characters deal with on a daily basis.
