Marceline

Is actually a creepypasta I made up and I'd thought it would be cool to make her.

So she is actually 17, but when she died from a car accident.
She died and was found by Slenderman.
He brought her back to home with her and introduced her to everyone and told her she was like them now.
She has a little scar over her left eye (but it's not visible to most), and bruises everywhere, and has stitches on her face and arms and legs.

She wears

The hoodie and this

She is not really a slut.

She tries to get Jeff pissed off and gets in fights with him often until Slendy separates them.

She is actually pretty kind to the others and will tease them sometimes.

She is pan
And has a crush on Jeff, Toby and you.
She doesn't show it tho....

She kinda liked kids, cause she had to babysit for the neighbors.
She hated her parents, and has bruises from her dad abusing her when ever he was drunk.
So one night she decided to kill him and she almost got away with it.
But the police found out and chased her, that's when she ran into a car and got tore up badly and died.
