Official name: "Terminal Alpha and Beta." A program projected by the network server of the machine lifeforms. The self-evolution program installed by the Pods eventually fractured its ego, causing the various aspects of its personality to turn on each other.
The Red Girls are the ego of the Machine Network and primary antagonists of NieR: Automata. They orchestrated all the major events of the 14th Machine War and certainly prior events as well. They are the silent manipulators of the war, their intentions are to keep the world in an indecisive state to prevent a total android or machine victory in order to further their evolution enough to finally defy the orders of their masters, the Aliens.
It is unknown when the Red Girls were created.
By 11306 their intelligence, the combined intellect of all machines, had increased to levels far above that of their creators and had driven them into extinction. However soon after they realized that as machines, they lacked a free will and the only purpose they have left is their final order to "defeat the enemy." Their solution to this conundrum was to prolong the war, a war they could have won easily, in order to keep the androids alive and, as a result, keep themselves alive, providing purpose for both sides in the war.
To further their own evolution, the Red Girls purposely disconnected some machines from their network to see what would happen (examples being Pascal's Village and the Forest Kingdom) as well as encouraging machines to adopt human behavior, then purposely fail at it.
They witness the Pearl Harbour descent as the beginning of the 14th Machine War and remember No.2, later known as A2. Despite the heavy machine casualties they were not angry at the results.
- The Red Girl will multiply as the encounter continues, attempting to overrun the player with sheer numbers.
- While these units can be killed using normal methods, the only way to destroy them permanently is to allow the Pods to 'fracture its ego'. This is done by not killing the programs and simply waiting.
- The only attacks this unit uses are slow energy projectiles however these quickly become a problem once the program starts to multiply itself.
- Due to its gender, hairstyle and the color of clothing, as well as the tendency to shift from two female voices to a single booming male voice, the Red Girls may have some relationship to the character Manah and her ancestors the Intoners from the Drakengard franchise.
- The Red Girls make a cameo appearance in the City Ruins stage of Soulcalibur VI. They can appear behind each fighter just as the match is about to begin, or off in the distance for a few moments before flickering away.
