I finally came across with designing the O.C. someone gave me. So, I decided to name her Crystal Quartz and she's a Dracony.

So yeah, this is Crystal Quartz. And she's a blank flank intentionally. That's because of her dragon heritage so she was never able to get her cutie mark.

Backstory:

Her mother, an average Earth Pony, was a scientist, and she volunteered to do a experiment that had to with mixing genetics. So as a result, her genetics and the genetics of a dragon were mixed together and then implanted into utero. From there, they decided to wait and see, and a few months later, her mother found out she was pregnant, which meant it was successful, but it was unknown how the foal would turn out. Several months later, Crystal was born and immediately, the scientists and doctors took immediate interest in her, for the fact that she had a mixture of dragon and pony features. She had the hooves and anatomy of a pony, but has the fore hooves, tail, wings, teeth, and eyes of a dragon. She was treated like a specialty throughout her childhood due to being a surviving experiment and for the fact that she's a hybrid. But at school, she was bullied for her heritage. She discovered she had fire breath when she got tired of the bullied and stood up for herself, but it resulted in the bully nearly getting burnt as Crystal exhaled fire for the first time. Her core body temperature is much warmer than normal so she's lava proof and is able to swim in hotsprings that could kill normal ponies. She's allergic to Dragon Sneeze Trees.
