We should keep the webcomic stuff in spoilers.
! IIRC Garou was clearly fooling around vs Flash and when he got serious he rekt him, and Atomic Samurai has as much wins on screen as TTM and PPM(Zero).
Remember guys, hero rankings in OPM mean NOTHING. MB has worse ranking than Atomic Samurai but has better feats and is a better overall fighter.
! Rankings are not perfect, that is true, but despite some misplacements they do mean something.
! I also do not agree that Metal Bat is above Atomic Samurai, MB is powerful, but his ability requires the fight to extend, MB wasn't getting a single hit on Garou when the fight started, he was hurt when it began, but that's what it actually take for his power to increase, only in the end he was going to connect the blow and win the fight, he could eventually surpass Samurai if the fight dragged on, but that's a condition that might not happen in some fights. Atomic Samurai 2 fights were against regenerating enemies, one which he fought alongsider MB, and the way i saw, he was very deadly, but, he was in a matchup where cutting enemies wasn't going to help.
! Darkshine fought an already more advanced version of Garou and even stated that, had Garou encountered some of the high ranked S-class, he would've lost before even being able show his techniques, and transformed Garou acknowledged that fighting Flash prior to his transformation, would've been trouble.
