A pony i made per request at my roleplay chat.
I asked them for something so i could make a pony OC, and someone suggested a red with grey pony.
So i came up with a grey pony with blood mane and tail. It's a blood magic user, and can control your whole body (just like that witch woman in avatar last airbender)
Name... because it sounds better then Cursed blood. and ... hum.. his own blood is black?
xD so story?
As a colt, he always was fascinated with blood, and the possebilities. It could heal, it could carry diseases, it had a huge impact on sight for ponies.... if you could control it.. you would control your life.... so he learned as much as possible of it...but in exhange of mastering blood.... he had to change his own, so only he could master it.... he turned his blood black, so it was immune to "all the useless magic" he enchanted his own tail and mane so he could use it, and absorb other's blood.... he has tasted the most common blood,,,, but he hungers for moe knowledge... alicorn blood.....
(fyi i just made this story up while typing)
