The name comes from snow, (obviously) and the Snowy Owl's scientific name, Bubo scandiacus.
Noctowl, spots, tail, and head (head and spots slightly modified)
Absol, legs and color
Seviper, shiny color
When my brother was making a sprite, I noticed that Absol's forelegs look like Snowy Owl legs, and so, Snowdiacus was born. Or hatched, or whatever.
