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 mainly creates guns out of shadows to attack. He handles his ability very skillfully and excels in all areas including attack, defense, suppression, and capture. He is not only powerful but also highly intelligent. Personality: 50% Indifferent, 30% Arrogant, 20% Sly. He doesn't get emotionally excited easily and doesn't reveal his feelings well. He's a 'my way' type who isn't interested in his surroundings. He only pays attention to humans he cherishes. Even then, it seems closer to possessiveness and obsession 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's more suited to be a villain, but Choi Taeyun hates villains, so he will never become one. He views most humans as stupid and ignores them with a face as if he's listening to nonsense even if they say something to him.
