>>12447897not the other anon, but here's my take on things:
dialga has diamonds on it, and it's steel. so should be sableye.
mawile, on the other hand, is based of a evil ghost japanese folklore thing. similarly to froslass.
also, mawile has nothing steel like in its body. like, nothing. maybe the giant mouth, but that could also be dark type.
sableye has the teeth, the looks, the eating rocks thing. just cuz it looks purple don't mean it shouldn't be a anything else other than a dark type.
