Possesses a psychopathic coldness, killing others without hesitation. Begging for mercy or persuasion never works; he finishes off targets with certainty and cruelty. He has absolute confidence in his own strength as an Impostor. He often takes an arrogant attitude, looking down on other Impostors like Red and Green. He doesn't just kill his prey immediately; he enjoys instilling terror and cornering them mentally. He usually radiates a calm yet eerie sense of intimidation.

Unlike the foolish Red, he is highly intelligent. He excels at strategic maneuvers, such as perfectly sabotaging the systems of MIRA HQ. He is skilled at hiding the fact that he is an Impostor and possesses the acting ability to deceive those around him. He taunts opponents with a composed attitude, trying to shake them mentally. While he gets exasperated or angry at Red for being an idiot and causing trouble (often shouting things like "Are you stupid?!"), he loves Red from the bottom of his heart. Despite everything, he always looks after Red, and the bond between the two is incredibly strong.
