Antique Jewels

Greedily is a clone of Rarity created by Dr. Nefarious in order to bare one of his Elements of Disharmony. Thanks to using harnessed magic from Discord, Nefarious made Greedily Rarity's mental opposite. Greedily is greedy, wants and steals anything valuable, and will refuse to share it with others. She has no cutie mark due to being freshly born.

History
Obtaining Rarity's DNA, Dr. Nefarious created a clone the same age as her. Using a machine fueled by harnessed power from Discord, Greedily became greedy and thievous, wanting anything that is worth value. But even with these dark personas, Greedily prefers to become a lesser threat with only her clone friends. And wanting to become not much of a threat indicates she still has good inside.
