User blog comment:Nonyy/Is hisoka a villan or an antagonistic?/@comment-5531609-20160409231254

Hisoka is the anti-hero of all the characters present in Hunter X Hunter, preferring to work towards meeting his own goals/making his latest prey stronger. He will do both good and evil, but at all times he's more of a chaotic neutral, working with the good guys occasionally so that he can either A) keep Gon alive, or B) raise Gon's strength and help him advance.

Hisoka has a sadistic personality and likes to only fight opponents that prove they're strong, like when he made Gon have to win a match in the 200s in order for him to accept Gon's challenge. The reason for this is reallly an unknown variable in Hisoka's past, and something that I wish we had more knowledge about.

It is also proven that Hisoka gets some sort of sexual satisfaction/gratification from the idea of killing strong opponents or seeing enemies with a great potential getting stronger. This might be just another extension of Hisoka's sadistic personality, but it might have greater implications for his character.

Also, it's been seen that Hisoka can be very caring about others, even if he's still being sadistic in the meantime; such as when in order to protect Gon from the Zoldyck family butlers Hisoka killed Gotoh, the head butler and one of the people Gon considered a friend of his.
