I didn't see Killua as an Ne-dom. In fact, I think Gon might be more of an Ne user than Killua is. Killua was always the more down-to-earth one between the two, and I suppose one of them had to be since otherwise they would've gotten themselves killed more than once with Gon's off-the-wall plans. Kurapika's type looks spot on though. Here's what I'd guess:Gon: ESFP - clearly
Killua: ENTP Trickster.
Kurapica: ISFJ -Revenge and solitude(I/F), Ryodan Pride (SJ). IxFJ's "Spider's" holocaust.
Leorio: ESTP - I concur.
Hisoka: ENTP Yet another Trickster.
Gon - ENFP - Think he showed a lot of evidence of using Ne.
Killua - ISTP - Seems to prefer to keep to himself more. Although that could be more of a by-product of his training than his actual nature...
Kurapika - ISFJ
Leorio - ESTX
Hisoka - ENTP - Doesn't the fact that he was able to come up with a horde of different uses for two seemingly plain abilities speak volumes about his Ne use? Very creative, and even more psychotic.
Kuroro - someone upthread said he was ENFJ, and I'm inclined to agree. He seemed more T when I first saw him, but after he, a hardened criminal, cried for his friend's death and then proceeded to demonstrate actual care for his subordinates, I changed my mind. Not to mention that he's freakishly good with people.
Too lazy to type the others, hah.
