Natasha Flank is a Half Earthpony half Wolf. She lives in her town of Mac Tíre-bhaile, or Mactíre as most of the residence of the town call it. It's a little town just out side the boards of Equestria. Natasha was known in the town as Mare le asal mór, or, Mare with a big rump. Fitting name for her considering her normal phasic. Of course, her name also comes from her power, an ability to cause herself to grow bigger, and that's what her human colt friend is about to find out about.
