The tentacles had many years where they were the dominant race on earth, after taking over they controlled humanity entirely. Tentacles are intelligent creatures who created and utilized technology to help manage the humans as well as help terraform the land to be more optimal for their lairs; the ZZ model is a reproduction assistance model which directly work with the young tentacles and the humans.
Xozz or Model ZZ Unit 10 as it is called in 'Fresh Meat' likely knows the location of the other ancient technologies and has worked to restore them between Overlord and Apocalypse, that is what 'the habitat' was, a restored facility for researching and creating androids; it has since become a lair for the red tentacles, a race of superior tentacles with the best traits from all of them.
The red tentacles are essentially the 'tanks or bombers', in terms of physical strength, speed, intelligence and endurance, they are the most advanced creature on each, with Olivia's Matriarch seed having helped create them.
Currently at the end of Apocalypse, Xozz recognizes the potential demon invasion as the biggest threat to the world, and he understands that only Elly is capable of stopping it because she can cross into their realm which is why he spends Alumae after her in order to rescue her from Olivia.
There is a whole lot of crap happening in the blue tentacle plains, Olivia and Ella have arrived, Sylvia is currently raiding that land, Laura is backed into a corner, and Alumae is coming to rescue Ella from the superior Olivia, on the other side of the continent Xozz, Rachel, Cecilia and The Black overlord all have their plans and April gets taken as a slave as Orange declares it's fealty to black all while the world is close to being invaded by a ruthless race of demons come to destroy them all.
who will prevail?
