Overall Rem's got about three shapes he can take, one that looks fully human, a half shape that resembles a Naga and his full Wyvern form, which is similar to a Chinese dragon but smaller. His 'mane' i just the top of his head and a little down the side then down the ridge of his neck. He had front leg/hands but no back ones and he does not have wings like the western dragons. He's very much land based.
His scales are closely interlocking scales, like snake skin. He's a very good swimmer and enjoys being in water. (he can hold his breath a long time) has no horns, his claws are stunted. and his colors are not very bright (he's more white/grey and some brown. Sometimes I paint his hair with brown in it, but most often just grey)
I'll explain about his nateral defences in the next picture LOL.
No matter what form he's in, he tends to keep his genitilia tucked in a front pouch. His human form having this pouch that unless he's engaged in sexual activity sorta gives him a featureless look of a ken doll LOL.
His penis though is like some animals actually has a bone, gives him a different shape and he can in heightened peeks actually 'swell' and get 'knotted' with his partner. But it passes after only a few minutes.
But he is fond of cuddling, partly to make sure he had not harmed his partner, and to fill that dragonic instinct to guard and protect a mate from other males.
He is a creature of pleasure. Enjoys reading (he has to ware glasses when he reads, I think they look cute!) soft things (fabrics, the warm flesh of a woman (or your man, he's not picky!) fine food and good books!) and the smell of books. He surrounds himself with luxeries, building his nest with many comforts.
Size difference between his different forms is very minor. The Wyvern of course being the biggest is possibly only about 15 feet long, and most of it is all tail. The half way is smaller, but still all tail, and the human form is closer to 7 foot, but still retains the same weight as the full form.
Rem is vegetarian. He does not eat meat. He holds nothing against those who do. It doesn't creep him out or anything, just if you invite him to dinner, pass him the fruit salad ^_^
