Nier : Automata

Intro Earth is invaded by aliens and their Machine Lifeforms with humanity driven nearly to extinction; humans take refuge on the moon and build androids to retake Earth. YoRHa No.2 Type B: or just 2B, is one of the protagonists of NieR:Automata. She is a YoRHa android created to battle the Machine lifeforms that have invaded the planet on behalf of the surviving humans. She served during the 14th Machine War. 2B is an all-purpose battle android, deployed as a member of the automated YoRHa infantry. 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 9S. In the English audio, 2B occasionally expresses a notably sarcastic wit in the face of certain situations. YoRHa No.9 Type S: or just 9S, is one of the protagonists of NieR:Automata. He is the main character of Branches B and D, as well as one of the main antagonists and final boss of Branch C.9S is a scanner-type android who served during the 14th Machine War. He has an attack function, but is overall an investigative android—a member of the YoRHa automated infantry unit, which excels in hacking intelligence gathering.As a scanner model, 9S is naturally curious about the world around him - especially the machine lifeforms. Usually working alone, he is deployed on the front lines with other S-type models, acting as YoRHa's main intelligence gatherer. According to A2, 9S is a "high-end model", meaning that he is one of the newest scanner types. As the newest model, he tends to dig deeper into YoRHa's secrets than his peers, often asking questions that those around him think he shouldn't be asking.
