Out of all of Satanick's Subordinates, Roc has displayed the most violent and rough temperament though he is not the type to show much emotion on his face. Roc's facial expression always remains the same no matter his current emotion. He retains the same smile no matter how joyful he is. Even when he is really happy or really worried, Roc does not blush or turn pale. However, he laughs when he is killing angels. Roc's job also involves security, specializing in "seek and destroy" missions.
