A2

YoRHa Type A No.2, or just A2, was a prototype of the YoRHa android line. All 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. A2 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 No.2. Unfortunately, A2 ended up being the last survivor of the YoRHa squadron after the mission, causing her to be declared a traitor and deserter by YoRHa Command due to the secrecy of the prototype YoRHa line. A2 then spends an unknown amount of time surviving alone, driven on by vengeance to defeat any machines and YoRHa units she comes upon on the way. Because of this, A2 refuses to interact with the other Androids on earth and develops a habit of never speaking unless she needs to.
