Houndoom

Houndoom the name says it all and the first dark type pokemon that raised a controversy in the christian community along with Murkrow, because of its sinister appearance, horns, and a skinny tail with a triangular tip at the end. In numerous dex entries it said they travel in packs and alpha males fight over the position of leader by butting heads or fighting like wolves for supremacy. When they breath fire the flames have toxic properties, and some people said its howl was the call of the grim reaper.
