I originally drew this for the Pokemon on Kommand meme, as my favourite dark type.
I love Hydreigon's design, and the fact that he sounds like he yells its japanese name (sazandora) in its cry.

I've always wanted to draw a "standing on the ground" hydreigon since he apparently doesn't have legs able to sustain its weight, so i've draw it standing on its legs, tail, AND heads.
