This is the Damien mini from Midknight Heroes upcoming Kickstarter (this is a 3D print of him that I got to paint).
With his whole demon aesthetic, I decided that he might fit with my Kingdom Death set. So I made him a face base, and painted him in the color scheme of the Dark Paladin artwork.
While I didn't convert this guy at all, I did consider what his bits might be good for. I'm going to have to grab a couple more when they come out. I've got a few ideas in store for him.
