Sting is a rather calm individual and is usually seen smiling; he rarely ever loses his temper. Sting believes that people who abandon their comrades are scum and does not hesitate to punish them for their acts. Curiously, however, he was angered when Natsu Dragneel said that fighting for his comrades was his reason for entering the Grand Magic Games. Sting seems to have no qualms about having killed his own foster father, thinking that it is natural for a Dragon Slayer to kill a Dragon. As such, Sting thinks that Dragon Slayers who are defeated by a Dragon are nothing but a disgrace.Also, as a Dragon Slayer, Sting stereotypically, yet comically, suffers from motion sickness, describing the phenomenon as one befitting of a "real" Dragon Slayer.
