User blog comment:Kuopiofi/Saitama - Absolute or Supernatural?/@comment-24053170-20160909172539/@comment-24053170-20160909174527

In fact, a lot of the users of both peak human condition and enhanced condition have accomplished almost all the same feats (and more) as saitama. And several of them have fought and won battles against literal gods and immortals (and a few of them have even beaten actual planet busters)

Based on that, this drops saitama so called invinciblity and unlimited strength ranking down a few pegs.
