Garou can do that because of cosmic radiation shi. Saitama has non physical interaction. Okhwang can just cut through them. Tathagata can use fate manip to defeat them. And they outscale the OPM characters vastly
Cosmic radiation is only part of the abilities, as is the control of space-time. The source of all powers is the knowledge of all the secrets of the universe given by God. And Saitama interacted with wormholes. Reread the manga.

Garou copied Saitama. And they can only copy martial arts.
