I think that Weapon is most important

All of the above. .....I can't make up my mind. x'D _{And they gotta be hot if male. :L}

To me, the color of the cloths is the most important part.

 

One of the things I didn't like all that much about the BbS characters design was the color of their cloths. The colors were boring, weak and most of it felt very, grey...

Aqua and Vanitas had some good colors to their cloths but still, something just didn't feel right about the colors.

 

Sora, Riku and Kairi had a good mix of bright and strong colors, at least in their KH1 attire. The KH2 and KH3D cloths are good too in terms of colors, better than BbS, but not better than KH1.

 

I feel like I'm unable to properly say what I mean. Hmm... Anyways I'm done rambling.

in kh? lol da hair its not even a question

Hair and they already ruined Riku's…

I think eyes should be a choice. I love the eyes.

 

Anyway, I say clothes. They've sort of become trademarked. (Can anyone even imagine Sora in a different style of clothes?) They're really true to the characters' personalities, and it's always a shock (not in a bad way) when they're in different outfits. Besides, this is one of the ways you can tell the characters apart (like Ven and Roxas). So...

The clothes are pretty damn important. Clothes are basically what attracts a person most to an anime character. That and their hair. And in KH the clothes actually have plot relevance. Eg. Sora's KH2 clothes, everybody who's worn an organization cloak, DiZ's outfit. All of that is actually relevant to the plot which is pretty unique in something like this.

The hair tends to be the most important, defining feature of a character when it comes to JRPGs.

yea i agree, lately it seems to be the hair. each character in the series seems to have a distinct hairstyle. my favorite btw has got to be riku from KH2 or axel's.

The hair easily. Just look at all of their hair. They use only the best hair gel for it.

Their personality...?

 

The eyes are the most important part for me in any animation, as they convey the most emotion and character. Sadly, Kingdom Hearts kind of misses the mark on this more often than not: the eyes tend to be too static and unmoving.

Their hair.  Definitely the hair.
