Krystal's OC:

(Drawn by Krystal himself)
His name is Sunrise Flammenwerfer, he wields an M60 and his coat is made out of gun cutie marks collected from only the most badass ponies.
He's like the duke nukem of Equestria and Fluttershy is his AR-15 Semi-automatic Assault Waifu. He also
has sadomasochistic love in his basement with Fluttershy and to top it off he says loco and amigo all the time.
