Hisoka Morrow

Hisoka is portrayed as a cocky, boastful, hedonistic, and self-serving man. He has an insane lust for blood and enjoys fighting strong opponents. While he does like Gon, Killua, and many others, he has stated that, for him, what is valuable one day could easily become trash the next, and he will not hesitate to kill anyone should they not meet his standards.

He kills people he deems "unworthy," regardless of age or sex. In a way, he is more amoral than evil, despite his sociopathic and malevolent nature. Despite his lust to fight strong opponents, Hisoka knows his limits - since he didn't try to attack Netero when he left his guard down or stated that fighting Chrollo Lucilfer was actually too much for him to handle. Hisoka is also shown to be a highly manipulative, cunning, crafty, and deceitful magician.

Throughout the series, he wears "women's" shoes and uses an alluring and seductive speech style typically reserved for females in Japanese. In the manga, he ends nearly every sentence with a suit symbol.
