Nicknamed "Hisoka the Magician," he is obsessed with fighting strong opponents and will kill without hesitation, whether for his own goals or on a mere whim. At the same time, he has a unique philosophy toward those whose talents he recognizes, choosing to wait for them to "ripen" before destroying them—sometimes even fostering the growth of Gon and his friends. Currently fixated on battling Chrollo one-on-one, he worked behind the scenes during the Andosa incident to prevent Chrollo from encountering Kurapika, who seeks revenge against him.
