Listen up! Mercy might've thought he had it all figured out with those magic powers and speed tricks, but Saitama’s got the muscle to back it up! When it comes down to it, Saitama ain't just a hero – he’s a one-man army. His “Serious Punch” is not just some fairy tale magic; it’s got the force to wipe out entire multiverses with a single swing of his fist. Mercy may disable moves and play games with reality, but against Saitama in serious mode, he’d be facing an unbreakable wall of strength and durability. Saitama’s got zero time for nonsense and can adapt to anything thrown at him. Magic? Please! He laughs in the face of magic! So when it comes down to brawn versus sorcery, I’m gonna tell you straight – if Saitama lands one of those serious punches, Mercy’s gonna be sent packing into oblivion, magic or no magic. Game over!
