How did the disassembly drones even defeat earth in the first place?
I don’t believe the disassembly drones received any training before fighting the military. In the show we see them acting as nothing more than common hunting animals, there isn’t any coordination, no grand plan, no objectives. They go apeshit and that’s pretty much it.
So how in blazes did they wipe out the military on earth. Most of cyn’s fighters weren’t even disassembly drones, just infected worker drones. And before someone says that “cyn is an eldritch horror that we see rip apart an attack helicopter in the show”. Cyn can only ever be in one place at one time, everywhere else should in theory be a slaughter for her drones.
On top of that, let’s say cyn turns out to be too strong. Mankind has enough firepower in the form of nukes to reduce everything on earth to rubble. Even if cyn won, how did she and her disassembly drones survive a near enough nuclear doomsday
