Some of the S-class heroes including Saitama, Fubuki, Psykos, and Garou reacting to Saitama vs. awakened Garou.
Note: by the way, this fight is the webcomic version which means I'm doing this first, and after that I will make Saitama vs. tatsumaki reaction (manga version or murata version), and finally Saitama vs cosmic Garou, soon they will be made.
Disclaimer: I don't own opm, ONE owns opm. Plus the cover page of this fanfic, it doesn't belong to me too, it belongs to someone in DeviantArt which I forgot his /her username in DeviantArt but go check out his/her art.
Also this is the part 1 of opm reaction.
