New oc: crimson princess/scarlet

Name: crimson princess/scarlet
Gender: female
Age: chronologicaly-317 physically- 12
species: unicorn/vampony
Appearance: small 12 year old looking body with a scarlet coat and black hair her eyes are naturally purple and she has a broken horn and a set of mechanical wings.
cutie mark: blank flank
Personality: scarlet is very nice and caring and smart. She would do anything to protect her friends as long as it does not involve hurting them. She is mentally 12 years old so she is moderately emotionally unstable. The crimson princess which is the vampiric personality is very unpleasant and generally only surfaces when scarlet is agitated or she needs to feed. She looks at ponies as food and generally doesn't avoid killing unless the pony in question is essential to helping her survive.
Random info: the two are fully separate personalities and you can tell between them by the color of her eyes and the appearance of her fangs. She is a shadow lord very similar to my other oc summerset. When she cries her tears are blood.

BIO: until 305 years ago scarlet lived the life of a homeless teenager. But it all changed when she got invited to a cave tour and went to star guides cave and ventured in with him... That's when she opened up a shadow lord tomb and got attacked by a vampire hybernating within. After the even star guide took her to a hospital where the crimson princess made her first appearance killing and fully draining the nurse. Needless to say, scarlet was fully freaked out. Realizing that scarlet could no longer live as a normal pony star guide brought her to live in his house. He treated her like his daughter for 70 years until he died of old age. When he died scarlet moved to an abandoned castle deep within the everfree forest and occasionally kidnaps ponies to use as a blood farm, however every year on the date of star guides death she returns to his house and pays her respects.
