A2

YoRHa Type A No.2, or just A2 is a prototype of the YoRHa android line, and combat data from her and her comrades were used to create the superior current lines, including YoRHa No.2 Type B and YoRHa No.9 Type S. She doesn't like to speak and often keeps to herself. Three years prior to the events of NieR:Automata, she was a member of the first YoRHa squadron deployed to Earth as part of the Pearl Harbor Descent during the early years of the 14th Machine War. Her alias at the time was No2 which is parsed in Automata as "Number Two".
