several bot survivors wander the map like nemesis zombies, but are completely harmless until he possesses them at which point he gets different abilities (e.g., a fireman with an axe that can instantly smash pallets, cop that can taser survivors).
survivors can attack him in this and knock him out, but hitting an unpossessed bot kills them and inflicts the survivor with insanity that makes everyone now look like the unknown and starts dropping doctor-like fake unknowns, and finally it enables friendly fire.
keeps the survivors on constant guard, allows the unknown to have either an aggressive or stealthy playstyle at his own leisure, and allows him to still have a power that revolves around weird imposter shit even if the survivors are fucking around on a discord call, with a bonus backup that they can't trust visual information anymore if they try and deliberately kill npc's to cuck him out of a power
