I'll do this for Lupus here.
*Lupus always has white hair, though with two distinct styles. When long, he often wears it in a low, loose ponytail, when short, it hangs loose and messy.
*He has a birthmark below his right eyes of his family's crest, a crescent moon over a four point star.
*He has a golden furred tail
*His eyes have three distinct colors/styles. they are either solid red and glowing, a bright pale blue, or yellow.
*He has a long, thin scar angled down his right side, starting just below the arm pit and ending near his navel.
*At times, he has a pair of bat-like wings. The membranes are white and tattered, and the skin around the supporting bones is a dark purple.
