- "Glory to mankind."
- — 2B
Her official title is Glory to Mankind.
2B was created an unspecified amount of time before the events of the game as part of the new line of YoRHa androids. She was given the designation of 2B as a cover by the YoRHa Commander, who gave her orders to observe one of the new Scanner models in action during YoRHa's operations against the machines. In reality, she is an Executioner model, 2E, rather than a Battle-type android as she is named.
2B's role was to ensure that 9S would not discover the true nature of Project YoRHa by executing him in case he dug too deep because of the natural curiosity programmed into him. Over the course of hundreds of operations, 2B was forced to kill 9S and wipe his memory countless times, an act that she came to hate for the pain it caused her after bonding with him over that time. The said project was supposed to assert that the human race still exists and that units like herself was to protect what was then, the remnants of humanity.
2B is a blade of quiet determination. As a combat android, she does not encourage idle chatter on frivolous subjects and is generally reticent towards others. She also has high respect for the chain of command and rarely questions her orders, unlike her partner. However, 2B occasionally expresses a notably sardonic wit in the face of certain situations and can even be hot-headed at times.
2B is prone to letting her emotionless guise slip in certain situations. As she and 9S become closer, she becomes more sociable and willing to engage in conversation. For example, she humors 9S when he talks about taking her shopping after the war with the Machines has ended and even uses his preferred nickname of 'Nines', though she quickly takes it back. 2B also exhibits thinly-veiled jealousy when 9S agrees to help the Resistance member in the Amnesia side quest, accusing him of falling for her. In the final battle against Adam, she expresses pure rage and raw hatred for the Machine Leader when she witnesses 9S's critical condition, swearing she would kill him.
In numerous moments throughout her adventure, 2B expresses frustration and pain with her true role in relation to 9S, hating the cycle they are locked in. She becomes emotional at having a chance to finally save the 9S she knows from Engels' attack at the beginning of the game but later shows anger at learning that his memory after their initial rendezvous was lost.
She is equipped with a multitude of weapons for close quarters combat and can attack from range using the Pod support system.
