A Netherwing drake from World of Warcraft. If you're interested, you can view the in-game model here.

I'll be getting one of these, soon. I remember my old one from my account I had as a kid, and I'd always fly around with him in the Outlands and see how far I could reach off the map without dying of fatigue. I'm excited to fly with my new one around Azeroth now that it's possible to do so!
