2B_9S_A2
2B, 9S, and A2 were all created by the YoRHa, an alliance of humans and androids, to fight in the war against the machines that had taken over Earth. 2B was the most skilled fighter of the three, with her emotionless demeanor making her a formidable opponent. 9S was the most agreeable and easy to be around, with his calm nature often putting others at ease. A2 was the most reserved and typically quiet, but when she fought, she was aggressive and fiery.
