Hammerhead manages to escape from Speed-o'-Sound Sonic after their fight and flee from the scene. Eventually he finds Saitama roaming in the woods and meets up with him.
Saitama asks where his followers are, but Hammerhead just punches him. The punch is able to do damage to the area behind Saitama, but he is ultimately unharmed. Saitama says that it was a letdown, so Hammerhead starts to use the full power of the suit as he was waiting to use it. Hammerhead uses his Spin Attack which reminded Saitama of himself. Instead of killing Hammerhead, Saitama slightly elbows the suit to destroy it.
Saitama tells Hammerhead not to do bad anymore. Hammerhead then runs off into the woods once again.
