@,@@Pucksterv,
Midnight Shadow would be my OC i would be using, she will be with Sombra, if you got to many ponies sided with Sombra then she could be against him trying to usurp him.
If you want the bio, i can post it if you want.
Name: Twilight Shadow
Species: Crepuscular Prenumbra (Shadow Changeling)
Gender: Female
Age: ????
Appearance: Twilight Shadow is a dark grey mare with red eyes, her wings along with her shell is red along with her wings. She normally goes around in disguise, her favorite form is a grey alicorn, which also has red eyes, her disguise's cutiemark is a dark cloud with a moon hidden behind it, though it is hard to see since she covers it with a cape, she found it hard to maintain a perfect shape after all.
bio: After the destruction of Canterlot, Twilight Shadow left the hive, something that is hard to do. once you leave, there is no going back. She decided to go and join Sombra and his dark forces, one day she hoped to be the leader of her own hive, which every Changeling dreamed of, however she did also wish to become a Queen like Chrysalis though maybe more powerful, with help from Sombra she could obtain this goal, perhaps she could learn about his shadow magic and change herself into something, darker, more powerful. So she searched for that same power, because Sombra must have gained it from somewhere, maybe there was some left for her perhaps. She decided to go find Sombra and learn the secrets of his dark magic.
