Possesses a psychopathic coldness, killing others without hesitation. Begging for mercy or persuasion never works; he finishes off targets surely and cruelly. He has absolute confidence in his own strength as an Impostor. He sometimes takes an arrogant attitude, looking down on other Impostors like Red and Green. He enjoys not just killing his prey immediately, but driving them into a corner mentally through fear. He usually gives off a calm and 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 teases 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 (shouting things like "Are you stupid?!"), he loves Red from the bottom of his heart. He ends up looking after Red no matter what, and the bond between the two is extremely strong.

Has the dishonorable official setting of being the "weakest and dumbest" among the Impostor faction. He doesn't know how to load a gun and is fatally bad at hiding the fact that he is an Impostor. He acts immediately without thinking deeply. He is extremely loyal and head-over-heels in love with his partner (and lover), Green Impostor.
