Hisoka doesn't even hide his game anymore. There's nothing normal about his look at Gon, it's something completely sick and disturbing. When he stares at it, he looks like a hungry predator staring at ripening prey, a fruit he refuses to pick right away so the pleasure will be more intense later.

His madness and excitement explode as soon as Gon exceeds his limits, and his psychopathic patience in waiting for the perfect moment to break him makes the character super creepy
