Chuunitrixx is easy to answer for, as Tree and I have a back and forth about how much power she can amass at a given moment overtime.
So, from the top:
Enderall is, effectively, a Zerg Cerebrate from StarCraft, and Chuunitrixx follows the Population rules of said game -- Traptrixx was a massive RTS mark, and StarCraft is one of my Top 5 RTS with Age of Empires and Age of Wonders, which heavily influence Project Necropolis Gothika.
Anyways, Enderall has an effective Population of 500. Each Unit takes up a Unit Pop, depending on its value.
Survivors of the Apocalypse have a Unit Pop of 1; they are a dime a dozen, basically, Zerglings. Enderall throws them as stuff, and they savage it.
Sentries have a Unit Pop of 3, and act like Hydralisks; shooting down targets with deadly efficiency. Proxies have a Unit Pop of 4, because they are, effectively, upgraded Sentries; like the Lurker is an upgrade Hydralisk, and, despite its limitation, it's far deadlier.
Concreep Mixers have the highest, current, Unit Pop for Enderall, at 5. They are moving Creep Colonies, supplying Enderall and her Units with constant healing. They are meant to be protected, zealously.
Now, the Upgraded Survivors have a Unit Pop of 2, save for the Overseer, with a Unit Pop of 3, which grants them advanced levels of automony, and for an Overseer, free will.
The Draft Horses and Dogs have a Unit Pop of 1. They literally exist to serve a function, and nothing else.
The Eggs had a Unit Pop of 25 each, because they are under Chuunitrixx, who has a Unit Pop of 50; if the Eggs are Ultralisks, then Chuunitrixx is a Brutalisk. Nothing is stronger.
So, there is, at any given moment, some combination of Survivor, Upgraded and Normal, Sentries, Proxies, and Concreep Mixers with a combined Unit Pop of 450.
Now, each of the Village has a Unit Pop that supports, fairly, 50 Upgraded Survivor Units or 100 Units in total, which is an upgrade from the Hamlet that had a Unit Pop of 20 Upgraded Survivor Units or 40 Units in total. Each upgrade requires Chuunitrixx to get explicit premission from Rodias, requires time to surplus Units, and the time to move them into place within a decent combination that protects and normalizes them.
And, lastly, Mimic don't sleep or eat. They mimic sleep and eating, but, they don't need it. So, they work and work and work. It isn't unreasonable to assume, 20~30 Survivors, working, around the clock, without need to sleep or eat, could very well accomplish what they have in a small amount of time with their oversight and lack of, significant, distractions.
It's a lot of numbers, but the numbers help me play fair with Chuunitrixx, because her Units are inexhaustible, so long as she has a steady supply of food and power to her Chapter.
