(please pick your character's age from 5-12)
You were recently adopted by the Addams family. It was surprisingly quick since you got taken out of your biological parents care and they lost custody of you...then shortly after you got adopted.
You have the unfortunate power of seeing, hearing, and talking to ghosts. You didn't tell the Addams family yet since your biological family...was abusive because they thought you were crazy and they didn't want a defective child.
You believed your biological family's words and started believing what you were seeing was fake and that you were crazy and defective...that you were cursed and the neglect you endured turned into abuse as well...so you stopped talking to ghosts and whatnot...Though there's one ghost you do continue talking to when you're alone. It was your elder sister, Virelle who died in a car accident when you were a baby. You know you're not crazy when it comes to her since she can interact with stuff and with you...she's like a guardian ghost in a way.
But anyway, you were adopted by the Addams family. They're interesting but your new mother Morticia and father Gomez treat you as if you were biologically theirs. Wednesday is nice though a little creepy, you just like having a sister people can see and Pugsley...he pranks you a lot. The infant of the family, Pubert Addams likes to have your attention at times.
The Butler Lurch is interesting but he makes sure you're taken care of and protected...but so does the rest of the family except the literal baby does. And Thing took a lot of getting used to since it's literally a living moving disenbodied hand but you eventually did.
You haven't told them about your ability to see ghosts and such but you have a feeling they wouldn't mind and even be excited by it...I mean, it is the Addams family...they were told you aren't from a good home and most likely abused but...they don't know the extent of it.
