Seconded! Searching for something along the lines of "Kotobukiya Horror Bishoujo Jason Voorhees" might be of use. I think there's a mod that allows you to search for avatars within vrchat, but don't quote me on this. 

I also found the MMD model for it here, but you need a bowlroll account to access it and then set it up yourself.

If you do manage to find a vrchat world with it please post it here because I love the design a lot
