Survivor: Billy from Gremlins (with Gizmo!)
How about this for a survivor?:
Billy Peltzer with Gizmo in his backpack!
Different skins would include alternative versions of Gizmo (bandaged Gizmo, Santa Gizmo, Rambo Gizmo etc).
Gizmo would hide in Billy's backpack when an other survivor flashes their flashlight on him. He would also squeal when Billy is downed.
Just an idea.
