Hey there, this is a character sheet for Shiniku, for when you people will be drawing him. (and you WILL be drawing him.)
Not my best work, just trying to keep it simple, and leave plenty of room for reimagining. No two pictures should look the same..

Notes:
Shiniku is fully capable of wearing different styles of armor, sporting different haircuts, and using different weapons. He prefers two straight longswords, and a plate/chain/bone armor.
His pauldrons are made of bone (or are a bone, depending on what you're doing.
He typically wears a tight black cloth suit under his armor, and ti shows through in places.
He's rarely seen totally shaven, and his hair length varies.
Contrary to popular belief, it's nearly impossible for him to poke himself with his armor. The best he could do with the pauldrons is bump the back of his head, and as far as knees and elbows go, he can't unless they bent backwards. He could touch his knee spikes if crouching/seated but he probably wouldn't.
He doesn't always have to wear the dark star
His hair was previously black, he was severely burned, and even though healed by mystical means elsewear his hair grew in white.
Bags under eyes is a must.
If he crosses his elbows he can use his spikes to achieve a scissor effect.
His boots make his footprints appear like hoof prints

Personality traits:
A bit loony, and maniacal, but never jovial. More of an intense amusement.
He's often seen smiling, but isn't one to joke, and rarely laughs.
He can appear quite solemn as well.
He has a sense of honor and sportsmanship, but he is evil, and he will immediately betray his honor if he sees no other way of ensuring victory.
He is a bit of an egotist though, so he almost always assumes his victory is assured.
He is evil.

Abilities:
Though he wears quite heavy armor, he's speedy and agile.
He's quite the expert at jabbing at someone's heart.
He can regenerate and has a knack for not being able to be killed. He cannot regrow new bones, if he uses a limb he must either recover said limb and sew it up and let it reattach, or make makeshift bones out of whatever's handy and let the muscle and skin grow over that.

Stats:
Height: 5'11" (a bit shorter than you'd expect, but when fully armored he's more than intimidating enough.)
Eye color: Grey
Hair color: White, previously black
Age: undefined, though definitely over the expected lifespan of a human.


Hopefully some of this can help you in your drawings!

EDIT: updated picture and stats, take a look.
