MLP Discord’s Ex-girlfriend Cosmos. Malice herself! (Humanized)  
My poor fluttercord-shipping heart was quit surprised when I found out about this lady!
 
I did add a few things to her appearance. According to the comic (75-77?) Cosmos was imprisoned into the stars and made into a constellation. I won’t tell the whole story, but I believe her constellation was made with six stars that formed a heart. So I gave her a tattoo of that. She also needs these stars to gain her complete form and get her powers. I gave her a necklace of this star so that she can hold a form, while the tattoo itself may have it’s own ability to keep her tamed. That being said, these facts are not true. I just added the tattoo and necklace to add more her her overall look.
 
Why is she back? No idea. Maybe to reform her - doubt it. I don’t think you can change the one who is the embodiment of Malice
 
I think it would be fun to draw her a bit. Maybe see how she would interact with Discord and Fluttershy? :)
