An bat pony royal guard OC from a story I wrote a while ago.  
I messed up his mane, it should have been dark blue, almost black.
 
Here is his description from the story:
 
While we were talking, I took the opportunity to get a look at him, most people think bat ponies are scary, there is all these old legends that say they were once pegasus who were driven out of their homes in the skies and were forced to hide underground and to feed on blood in these dark lands devoid of vegetation, or how they kidnap children during nightmare night to offer them in sacrifice to Nightmare Moon. Lies and foolish superstitions, all of it, these kind of story probably originated from the fact the bat ponies always lived on the fringes of our society, answering to no one except for princess Luna, who was the only pony that has ever got their trust. I, on the contrary, found them fascinating, they were always surrounded by an aura of mystery, like if after living in the night for so long, they had absorbed it’s secrets into their very being.
 
Our friend Buried Star was a fine specimen of his kind, he was of an average size, smaller than an unicorn but taller than a pegasus. His two golden eyes looked like sunlight coming through the cloudy sky of his cinder coat. His fur was short, with the exception of the base of his neck, which looked like those fancy scarves that the nobles of Canterlot love to wear. Each time he opened his mouth to talk, I could see shining with the light of the crystal tower, two strong and sharp canines that made me glad he was a vegetarian. His calm and low voice was mixed with a faint rattling like a cricket. At some point, he shifted the position in which he sat and stretched his wings, very different from a pegasus ones they had no feathers, instead, they were made of a very thin flesh membrane, the elongated bones making it’s frame were visible and, illuminated by the light of the huge phosphorescent crystal beside us, I could see a scarlet maze of tiny veins coursing through these wings that looked like the decaying claws of a corpse.
