This is long but it's all important, especially his dagger and necklace:

Kosuke stands at 6'2" and his entire body is lean, toned muscle. He has black hair down to his waist that he usually keeps tied up in a ponytail. However, there is one lock of hair that just doesn't like cooperating and hangs along the side of the face (not lower than the chin). Atop his head are two fluffy black wolf ears. His eyes are an icy blue that seem to stare straight into your soul. He has a long black wolf tail that he doesn't bother hiding, he simply pokes a hole in his pants so he can stick the tail through it and be comfortable. His canines are slightly elongated, giving him fangs rather than regular teeth. His nails also grow stronger and sharper than regular human nails, growing to a point, giving him claws rather than nails. He usually wears a black tank top with some sort of alchemic-looking symbol in blood red on it (although in reality it is more of a satanic alchemic symbol), black cargo pants with a couple belts and chains clipped to them, black boots, and a black trenchcoat. If he was to take off the trenchcoat and tank top, scars littering his body would be revealed (although these can be hard to see). He has a particularly large one diagonally down his back from a fight. There is one scar he can't hide with clothes. He has a scar that goes from the top right of his face, across his nose and down to the left side of his chin. He had been lucky with that one, if it had been an inch lower he would have lost sight in his right eye. Another reason for his black trenchcoat is that he always has a small dagger strapped to his thigh. The black handle is ornamented with gold flames coming out of a blazing silver skull at the base. He also wears a thin silver chain around his neck with a tribal-looking pendant on it, something of a tribal phoenix. He also has a gold hoop earring through his left ear. He changes between a fire user, a darkness user, and a necromancer depending on the story.

Excellent ref, everything except trench included (I almost like it without the trench this time): http://i294.photobucket.com/albums/mm102/mwang7/Rescreatu/kosukechains.png

Choice 2:

Kosuke Omni:

I know Kosuke is stardusted on my profile, he shouldn't be in the pic. He's kind of a darker, more violent sort of Creatu. Usually he'll have a dagger and maybe some chains. His symbols are different from a normal Omni as well. He's definitely the fighter of the group and is stronger than any other of my Creatu. At the same time, he's very protective of those he cares about.If possible, having Kosuke wearing the special pendant he always wears (it's an important symbol for him) and maybe incorporating his ear piercing (but if it looks dumb that's unimportant) would be nice.

Here's more details about Kosuke:

Symbols: alchemic-looking symbol in blood red on it (although in reality it is more of a satanic alchemic symbol)

Body: he has several scars from battle, many are nearly impossible to see but the most prominent are a particularly large one diagonally down his back from a fight and a scar that goes from the top right of his face, across his nose and down to the left side of his chin.

Dagger: The black handle is ornamented with gold flames coming out of a blazing silver skull at the base

Important Pendant: a thin silver chain around his neck with a tribal-looking pendant on it, something of a tribal phoenix.

Earring (optional): He also has a gold hoop earring through his left ear.

Depending on the rp/story he can be a fire user, darkness user, or a necromancer, just to give a little more of an idea of his personality. Because of this, he tends to have tendrils of energy flowing around him (see reference for these)
