From the following American film villains, which one has no absolute/one identity?

Yeah ghost face doesn't! every time u see that mask I it is a different person behind it! that is why trust no one! because! everyone is a suspect! loved the remake! have watched all of the scream movies! so if they are making a new scream I want to be in it so y'all! know where I am at! if y'all need anything!

I don't like the ghost 👻 fav

I was really scared of pinhead !!!
