With a few exceptions, the canon characters all look the as they did in Slayers TRY. It is safe to say that I do not need to include descriptions for Lina, Gourry, Amelia, Zelgadis, Sylphiel, Martina, Zangulus, or Naga. With other canon characters, some of the changes were based on practicality: i.e., Luna doesn't wear her waitress uniform while travelling, etc. I tried not to go too crazy with the changes that i did make, though.
First, let's start with Val:
Hair: still pale green, but instead of the gravity-defying do, he wears it as he did before Gaav made him a Mazoku. He does keep the black headband though, but only as an adult.....
Eyes: once again, no change here. he still has his orange peepers
Clothing: no idea has of yet.......definintly something that won't hamper his wings. Mabye a masculine halter top? ^_^ And pants, of course.
Other: no more scary horn, being reborn as an Ancient Dragon has the tendency to remove your Mazoku side, I would imagine. however, he keeps the scars on his face, kind of a constant reminder to everyoneof who and what he was. he also retains the ability to only partially change into dragon form, although now he can once again fully transform.
Next, we'll go with Anya Fa'sharn
Hair: red. the length is roughly between her shoulder blades and her waist, and she has layered bangs that frame her face. if that's not too clear, have a look at her picture in the gallery.
Eyes: leaf green most of the time, but when Anya is......um, how do I say this without dropping spoilers all over the place......? when Anya is "under the influence of chaos", her eyes are a scary, unnatural shade of blue.
Clothing: her shirt is white, with long loose sleeves that are tied in the middle of her upper arms with black ribbon. she wears tight black pants, and over her ensemble she wears an ankle-length coat the same shade of green as her eyes. the coat has no sleeves and only buttons to her waist, leaving the bottom open. (think of Rinoa from FFVIII) she also wears dark grey boots that come up to mid-calf, with the tops turned down.
Other: throughout the course of Slayers CHAOTIC, Anya gathers four pieces of jewelry: 2 bracelets, one belt, and one necklace. it's a matched set, so they all pretty much look the same, just bands of engraved silver with a single blue, diamond-shaped stone set into the metal. she also wears a silver circlet on her forehead that contains a similar blue gem.
Time for Filia:
Hair: no change here, just the same long blonde hair
Eyes: Filia's eyes look like they are caught between blue and gold at this point. I figured that if the other Golden Dragons that we've seen before have gold eyes and Filia has blue, then at some point in thier lives those eyes change, like when a kitten starts to mature. mostly they are still blue, but with gold radiating out from the pupil. See the picture for an example.
Clothing: one of those things that I felt it was necessary to change, if only for the simple reason that a dress is not the greatest thing to travel around and fight in. She now wears a white shirt with short, poufy sleeves that have ruffles below them, a dark yellow corset-type thing that laces up the front and back with brown ribbon, and dark, royal blue pants. Filia's pants are loose, flowing, and gathered at the ankles. she also wears brown ankle-boots with a low heel.
Other: Filia no longer wears her hat, and her pointed ears are now visible
Xellos's Turn
Hair: shoulder-length and purple
Eyes: violet, more "human" looking
Clothing: Xellos now wears a long, belted tunic (gray) over darker gray pants. The belt for the tunis is a deep blue sash, and he wears a heavy cloak over this. The cloak has a collar similar to his old one, but with a hood he can pull up to hide his face. The cloak is dark bluish-black, and patterned with silver stars. It also has silver fringe around the hems. His boots are black.
Other: He carries a staff made out of pale wood, the head fashioned to resemble a dragon with a milky-white orb held within its wings
