Is your OC a Mary sue?

Christine M. kastivava/Black cloud-Creepypasta Oc (something i forgot to post

Creepypasta OC
Creepypasta OC
/Name: Christine M. Kastivava
Nice name.
/Nickname: Most commonly known as Black Cloud. This is because her dark aura that most surviving victims of her's explain and her intimidating feeling just like that of a major storm that you can see with the dark clouds.
Seems like the feeling you get around a serial killer
/Age: Rumored to be about 25 to 29
*bows down at your perfect age*
/Height: 6'3
Tall.
/Gender: Female
/Looks: Christine has no known eye color or hair color & length because most don't live to tell about and if it is told, it's kept a secret. She has an oval shaped head with no distinct jaw shape or facial features, and she's skinny as all fukin hell to the point of unhealthy-ness, possibly hinting starvation of some sort.
How come it's a secret? Jeez, slender man Jr.
/Clothing: It varies on the day, and who she's killing. She likes to play around with social mechanics of other humans, therefore, she tests out how others react with different styles.
Awesome! Finally not just a routine outfit.
Personality: Christine has a odd tendency to play around with humans, almost like social experiments before killing them in many different ways. She is very intelligent and if anyone questions her intelligence, she gets angry really quick. Christine's pride is a factor in that and can get her into trouble sometimes. If you're not her target, she will tend to stay away from you and be a little nonsocial emo. It's not a faze mum I kill people ankfkdkwkqkp She may come out directly to her targets and act like a kind, playful, and energetic girl to befriend them. After a while of learning about them, she will choose how to kill them.
Seems like a correct way to murder someone.
Likes: Though she's a killer, it doesn't mean Christine has a bit of a humane side. She loves reading, drawing, nature, likes black roses for some random reason, i.e, no one knows why. Dislikes: Her intelligence being questioned and when her kills don't work like she wants them too. She actually doesn't like killing and doesn't like blood and the only reason she's a killer, is because she's forced to kill for fear of her own life.
Usually murderers like murdering.
Weaknesses: She's never really shown any, but it is known that whenever she is killing, Christine doesn't show too much joy in it, meaning that if she has to kill to many people at once, she may mentally start to breakdown. This is not insanity, it's just a breakdown of stress and fear. Another thing, she doesn't work well under stress.
No one does, chrissy.
Backstory: There are many rumors about how she became a killer. Some say Christine was abused and became a killer out of rage, which is sooo not true might I add. Others say that she is part of a killer group (not the Slender Mansion crap), *bows down to you* and she's forced to kill or she would be killed herself. Along with these two theories, there are other stories that branch off of them. If anyone does find out, they are usually dead or they disappeared.
Extra: Christine does have a few disorders including Autism, Asperger's Syndrome, a slight bit of depression from having to kill, Sensory Processing Disorder, and ADHD. (I only put these here because I have these disorders and I do sometimes accidentally express symptoms of these disorders. I try not to express them because I know the sensitivity for others that have this because of what people will do with the disorders. (i.e, romanticize them, make fun of them, self-diagnose themselves, etc)
Commentary: She's pretty original, and she's the closest to a real serial killer I've seen.
