Chapter 14

 (お前など知らん, Omae Nado Shiran) is the fourteenth chapter of the OnePunch-Man manga series.

Summary
Saitama, looking for The Paradise Group had ended up in the woods outside Mr. Monier's mansion, when he comes upon Hammerhead. Hammerhead stops in front of Saitama, who then challenges him to a fight. Hammerhead throws a punch and smashes Saitama in the face, but it hardly even moved him and only left him with a mildly perplexed look on his face. Saitama expresses his disappointment in Hammerheads strength. This enrages Hammerhead who then puts his suit on full power and uses his "windmill attack," which reminds Saitama of how he used to fight as a child. Saitama then reaches out and easily stops Hammerheads attack and then punches him in the stomach, causing his suit to shatter. Hammerhead then runs off in the nude, promising to not do anything bad anymore. At that point Sonic arrives and asks where Hammerhead went. Sonic then throws a kunai at Saitama who catches it, and then attempts to stab Saitama who stops him by grabbing the blade and breaking it. Saitama attempts to explain that he isn't a member of The Paradise Group but is instead a superhero, but Sonic doesn't believe him. Sonic then notes that the problem now isn't who Saitama is, but instead the fact that Saitama had managed to block two of his attacks. Sonic then challenges Saitama, stating that his pride won't allow him to lose, but Saitama then calls him out on the fact that he just wants to try out techniques on him and that he could tell by the childlike smile on his face. The scene then shifts to Hammerhead, who is being beaten up by two robots. The robots berate him for stealing the battle suits from "The Organization" and then leave him for dead.
