|Weiss, you dumbass!|
SPOILER ALERT - Plot details for NieR follow.
Devola and Popola are revealed at the end of NieR to be androids, and that their purpose was to monitor the Replicants and facilitate Project Gestalt, along with many other Devola's and Popola's in other cities. They failed in their duty, however, as when Devola was killed by Nier, Popola is driven to insanity and attempts to kill everyone. She failed to kill Nier, however, so he went on and killed the Shadowlord, sealing the fate of humanity and causing Project Gestalt to fail.
For Devola and Popola's part in the extinction of humanity, nearly all other models of Devola and Popola were destroyed, with the exception of the two that appear in 11945.
|That is why you, the YoRHa forces, exist:|
SPOILER ALERT - Plot details for NieR:Automata follow.
YoRHa is an operation that resulted in the production of a special type of android several years prior to the events of NieR:Automata. It is revealed that the true purpose of YoRHa is to perpetuate the lie that humanity is still alive, despite having gone extinct thousands of years ago as a result of Nier killing the Shadowlord. The announcements heard throughout the game is actually a recording made by YoRHa to make others think humanity is still on the moon.
It is also revealed towards the end of Automata that YoRHa android's Black Boxes are actually made from the cores of machines, as it was deemed inhumane to use traditional androids in the project, as the intention was to kill every last YoRHa unit once the machines were defeated. This, along with humanity being extinct and 2B's death, causes 9S to fall into insanity by the end of the game.
