Here is the coolest character of the series - and no, you cannot argue this. Even though the picture is bad.

Gender male.

Age = About 12 years of age.

Physical Description= Hair is whitish lavender with spikes which are unrealistic, though not quite so unrealistic as Gon. Eyes are dark blue and Hiei style, except cuter. Is a little bit taller than Gon. From time to time his eyes turn REALLY creepy, mostly whenever he is about to kill someone or threatening to kill someone - seriously.

Personality = Killua is sort of two-faced, as he shows different faces to Gon and to the rest of the world(ie, family, Clapika, Reorio, whoever else he meets with) which is respectively a fun-loving kid who doesn't really like murder or killing and a cold-blooded murderer who will stop at nothing to achieve his goals. Well, perhaps he tones it down a little for Clapika and Reorio, but for his family that's normal and the way they expect him to be. He has a lying problem, that's for sure, and can lie with a very straight face (so straight that Togashi has to tell us when he's lying). But he is also a fun loving kid, and laughs a lot, which is probably why Gon can stand to be with him. (Other than the fact that Gon is the male version of a ditz...) I am kind of confused about whether I like him as a character or not, because in recent developments he has shown that he is not above using Clapika to get money to help Gon out in his search for his father... which is disturbing because Clapika is supposed to be one of his friends, as well....

Clothes = In the Hunter tests he wore a dark turtleneck under a lavender T-shirt along with ordinary shorts, but after the tests he changed clothes frequently.

Weapons = Killua doesn't have any hand held weapons, nor does he need any. The Zoldicks have been doing either weird genetic experiments or selective breeding for many generations, so their entire body can become like weapons. For example, Killua can transform his normal hand into a veiny clawed hand, and do major damage to almost any opponent.

Nen = Killua is Henge Nen, which means that he is lying and shifty naturally as a personality. He wasn't happy when this was pointed out to him, but he accepted it in the context. (Besides, he knew it was true.)

Family= Oh boy.... where shall I start? Killua's entire family is a bunch of trained assasins who work only for cash. They're not afraid of anyone... except maybe the Ryodan, but they stay out of their way when possible. Killua's father is an older, buffer Killua. Killua's grandfather is a really old, wizened Killua. It's a genetic thing. But his mother must have thrown a work into the genes because before Killua she had Illumi, Milluki, Kalluto(or Cult) and another child that must have already left the house. And they're all weird. (There is absolutely no brotherly love, either. It's dog-eat-dog. The strongest child - who can beat, if not kill, all the others - is the one who inherits the family buisness.) The entire family lives on top of a mountain in a guarded facility, and inspire very direct loyalty from their staff. Killua beat up his mother and his brother Milluki when he ran away from home to go to the Hunter tests.

Quest = Killua had no quest when he entered the Hunter tests; they were just a lark for him. Mostly he wanted to go and do something away from home, and he just used going to the tests as an excuse to run away. After the tests, he still had no goal(even though he failed them) and is currently helping Gon to find his father.

My Opinion = Well, like I said before, Killua is a so-so character for me. I definantly think he's one of the most interesting characters, that won't change. No way this child assasin that for some reason has renounced his family and killing too for no direct reason could be anything less. But it will be interesting to see if a character that is naturally lying and shifty can ever be a real good guy. I just hope that Gon won't let him use Clapika for money, because that's UNETHICAL!!
