Taehoon is a stoic individual with a cold exterior, who can be brazen and reckless. He doesn't seem to care much about how his actions affect others and doesn't hesitate 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 to give them something he wants by hitting his friend in front of them. He shows a strong belief that he only needs Taekwondo to beat everyone and dominate the UFC with him.
