Crescent Eyebroll is a slim man who wears a helmet with a crescent moon on it. His suit also has a crescent symbol on the chest area.
He is shown to be a strong, determined and honorable hero as he immediately exclaimed about saving the hostage from the Monster Association and later claimed that the heroes are going to take back the district in Z-City.
Crescent Eyebroll is one of the heroes recruited to the Monster Association raid support team. While he fights the monsters, he is impressed by One Shotter's abilities and is later seen amazed at Green's ability to control plants coming out of his body. When Green constricts the monsters, he tells Crescent Eyebroll to finish the job, and he eliminates the constricted monsters with his saber.
Later, when Rhino Wrestler comes into the battle, he is one of many heroes to attack the monster simultaneously and uses his Crescent Moon Sweep, but is effortlessly batted away by the monster.
He stays above ground with the rest of the support team while the S-Class heroes infiltrate the Monster Association headquarters.
Nyan confronts the support team and defeats Crescent Eyebroll and the rest of the heroes.
Crescent Eyebroll is called for a meeting to inform several heroes and citizens of City A about a new apartment complex the Hero Association has introduced. Green accompanies him, and Crescent Eyebroll asks him what the meeting is about. Green replies by saying the Hero Association is raising funds by selling apartments as high-class property. Then, the speaker calls upon Green and Crescent Eyebroll to inform the crowd that they will protect the apartment complex from any dangers. Crescent Eyebroll is enraged that they're being treated as security guards, while Green laments that this was the reason why they made the rent free. As the presentation continues, a new security system created by Metal Knight is announced, and the speaker makes the assertion that Metal Knight's defense system can do more work than all the A-class heroes combined. Green states that the statement is quite a humiliating way to say it, and angrily stands by while the presentation continues.
