Kage

Immortal shapeshifting wolf boy. (Can also shift into a hawk, cat, or wyvern) 

[notes] 

White all over, with pale green eyes. Fur is cold and spiky, similar to his personality. His cheek fur (or head fur, depending on whether he's drawn with any), tail, and a diamond on his forehead are all slightly brighter white than the rest of his body. Often drawn with lines under his eyes and rarely smiles; he's a grump, after all.
