who is the strongest character in this series?

Hesoka cause he is super smart/strong and good with cards .

My bet goes on either Hisoka (cause his hawt) or Kuroro (i love the darkness that he is)

I like to explain more, but i guess i dont wath HXH anymore *sighs*

Hisoka rules ,i mean he's nearly unbeatable though i would take Kurapaika into consideration as well.

Hesoka the best !!!!!!! :smile::smile::smile::smile::smile::smile::smile:

Killua's father and grandfather, because in the last episodes they showed thirs true strength agains the boss of the Roydan :D:

For me kurapika because he is good to his power and also he is smart !

i gotta give it to oji-san killua's grandpa he just is one crazy old man haha
