Well they cant clone them without DNA, duh.
Maybe they are like danger holograms. If someone comes who is not Zealian and is like an intruder, an image of them will be shown to who it is.
BTW, whenever you edit your chracters using one of the emulator keys, other things are revealed to you, you know. Like monsters in the background for no reason which shouldn't even be there, cut off sprites, etc.
