Hammerhead prepares to fight Saitama by powering up. Saitama punches his entire suit off, seemingly feeling sympathy for him. Hammerhead runs away naked. Then Sonic shows up and tries to attack him, but Saitama explains that he's not one of Hammerhead's followers.
But now that Saitama has blocked his attacks, Sonic still feels he must beat him. Saitama accidentally punches him in the crotch. Sonic then declares that he will train until he can beat him, while he barely stands from that one punch.
