Anyone who has been in the creepypasta fandom long enough knows about Nina the Killer. She is called a Mary Sue by many, including me. Everything's a mess.
First off, her story is a complete rip off of Jeff's. The only difference is that her bullies didn't set her on fire; it was Jeff. And she stitched her eyes open instead of burning the lids off. Other than that, not much is different.
Another thing is her outfit. She kills in a mini skirt. Coming from a girl's point, I would say that it would be incredibly hard to kill in a mini skirt. Especially since a lot of people in the situation would struggle and fight for their lives. I know I would.
The biggest problem is that she is a fangirl. The type that I would never want to be. All she wants is to become Jeff's girlfriend or something. You can tell by the looks. It is very cringey to think about. Fangirls are already a huge problem in our community and they keep multiplying. There are so many who want to marry a pasta or go to the Slender Mansion, which is fan made, might I add.
I'm sorry this is so short, I just didn't have much to say about Nina. Until next time, guys!
EDIT : I recently read a rant that said Nina's concept was actually pretty original, and I have to agree. The crazed fangirl isn't used as a basis for a character in Creepypasta much, so I have to give props to the creator for that. However, doesn't mean I automatically like her. She is still annoying.
