Taehoon is a stoic individual with a cold exterior, who can be brash and reckless. He doesn't seem to care much about how his actions affect others and shows no hesitation to be violent towards other people, whether they get in his way or not. He likes to beat people up for his own enjoyment, sometimes even threatening them to give him something he wants by beating thr friend in front of them. He shows a strong belief that he only needs Taekwondo to beat everyone and dominate the UFC with it.
