2B (short for "YoRHa No. 2 Type B") is one of the protagonists and initial player character of the 2017 video game Nier: Automata. A humanoid combat android created as part of the YoRHa squadron, her mission is to liberate Earth from hostile machine lifeforms created by an unnamed alien race. Her Type B designation indicates that she specializes in front-line combat, and she is able to wield two weapons and use a large variety of combat styles. Her personality is cold, collected, and quick-thinking in dire situations, a trait of her model line that was inherited from her predecessor A2, whom she resembles perfectly. She disdains open displays of emotion, believing them to be unnecessary, although she hides emotional trauma and anger over the missions she is forced to complete.
