Description taken from DA

Had to heavily tone down Derpy's chest for this image since she's normally drawn with them much larger by me. I didn't have time to expand on this more with today being the anniversary of Star Wars so I did a quick drawing of Derpy from MLP as a Sith Lord for the Separatist Army.

Derpy was approached by the Emperor and promised a role as a Sith Lord despite her being pure-hearted. He saw her derpy potential regardless of her standing. She refused, but then joined immediately after she was promised muffins. Now Derpy is going across the galaxy doing her duties as a Sith, capturing planets and fighting the Jedi scum in the most derpiest way possible...all in the name of muffins. She's very tough to defeat as well do to her derp derp nature. The remaining Jedi Order are having a hard time bolstering the Republic defenses against such derpiness.

May the 4th be with you all today.
