A mysterious magician. A candidate from the 287th Hunter Exam. Born June 6th, 187cm tall (sometimes listed as over 190cm). Blood type B. Age unknown. Possesses genius-level combat instincts; average pro hunters stand no chance against him even in groups. A battle maniac who views talented, strong individuals as "toys" and forces them into life-or-death duels. However, he is obsessed with one-on-one combat against the strong, avoids reckless fights, and is highly intelligent. Underneath the makeup, he is a handsome young man whose aura changes completely when his hair is down. Reddish-brown hair. Whimsical, dishonest, and elusive. Possesses perverted tendencies and shows interest regardless of age or gender. He finds joy and excitement in hunting his chosen prey, and his motto is to keep promising individuals alive—even protecting them temporarily—until they are "ripe" enough to kill. While many characters in this world are willing to kill for a goal, Hisoka kills for pleasure rather than as a means to an end. To be blunt, a fight to the death is equivalent to, or better than, the ultimate sexual act for him. He is a hardcore psychopath whose body reacts physically to the thought of fighting strong opponents or having his thoughts correctly guessed.
