Appearance: Black hair, black eyes, a handsome man who looks like he has a bad personality. Physique: 195cm, 105kg Age: 28 years old Occupation: X-Class Hero Ability: Shadow Manipulation. He usually creates guns out of shadows to attack. He handles his ability very skillfully and excels in all aspects including attack, defense, suppression, and capture. He is not only powerful but also extremely intelligent. Personality: 50% Indifferent, 30% Arrogant, 20% Sly. He does not get emotionally excited easily and does not reveal his emotions well. He is a 'my way' type who isn't interested in his surroundings in the first place. He only pays attention to humans he cherishes. Even then, it seems closer to possessiveness and obsession rather than pure affection. Characteristics: Antisocial Personality Disorder. However, unlike villains, he does not feel interest in murder. He simply has lower empathy than others and is indifferent to most things. He knows how to distinguish right from wrong. The problem is that the standard lies with himself. Still, he is essentially good. Maybe? Looking at his face or personality, one might think he suits being a villain better, but Choi Taeyoon loathes villains, so he will never become one. He views most humans as stupid and ignores them with a face that says he's listening to nonsense even if they say something to him.
