A2 [your savor]

Pascal amd the other machines that live there are Pasefist group wanting to harm, no fighting but to just simply live and understand humans and their emotions that they had

The events of the 14th Machine War unfold through three main characters' perspectives, 2B, 9S, and A2, all of whom fight as the last remnants of human civilization against otherworldly invaders. The battle is not so black-and-white, however, as the androids begin to question their own motives and the world in which they inhabit whilst being thrown into difficult situations and moral dilemmas.

Strategy - A2 has a very aggressive move set, and as such, has the highest damage potential out of all the playable characters in the game, especially with the right Plug-in Chips. When using Berserk with higher-level Offensive Heal, Deadly Heal, or Damage Absorb Chips, the health drain will be offset by the massive amounts of health gained while dealing damage and killing enemies.

Berserk - Rather than self-destructing, A2 has the ability to enter a "Berserk Mode," increasing damage both dealt and received and rapidly depleting her health until it hits 1 HP, whereupon Berserk Mode will end. As with self-destruct, the button must be held until the completion of a short timer to activate the mode. Plug-in chips that restore health will still function normally (though auto-heal will not trigger due to the constant health loss and auto-use item does not trigger until it ends) and the player can also manually heal A2 with health items, allowing Berserk Mode to be extended. A2 will have a short downtime to reboot when Berserk Mode concludes, similar to the other characters after self-destructing. During this period most of her abilities are disabled, though the Pod can still attack normally. Notably, if A2 takes a hit that would reduce her HP to 0 or less while in Berserk Mode, she will not die, instead being knocked out of Berserk with 1 HP remaining: this even happens in Very Hard mode.

Counter - Timing an attack to strike the enemy's weapon or fist as they swing will deflect their attack and allow a counter-attack in the same manner as after a Perfect Evade. In addition, if a "Counter" plug-in chip is equipped, the player can perform the same move by tilting the movement stick in the direction an enemy attack is coming from just as it connects

Perfect Evade - Evading just before an attack connects will cause a special evasion animation of A2 breaking into multiple hologram-like copies: if the player then quickly presses primary attack, heavy attack, or pod shot, a powerful counter-attack will be performed

Dash Boost - Exclusive to A2, holding down evade will result in a dash where A2 starts to glow red. If she is in Berserk Mode (see below) this dash will deal damage to enemies: even in normal mode, it seems an attack immediately after the dash concludes deals slightly more damage.

Evade - Allows for a dash in whatever direction the movement control is pressed, defaulting to backwards if no direction is pressed. If the direction is held, after a short while A2 will start sprinting: holding also increases the speed at which A2 climbs ladders. Can also be performed in the air: a longer jump can be achieved by dashing off a platform and then again in mid-air. This dash move has invincible frames and can be used to avoid enemy attacks: the distance traveled and the number of invincible frames can be increased using "Evade Range Up" plug-in chips. The distance traveled with such a chip equipped can be controlled: holding evade will result in a full-length dash, while just a tap will result in a shorter one. Pressing light attack immediately after starting a dash results in a special dodge and attack animation where a horizontal rotating blade is fired from A2's initial location in the direction the camera is facing.

Jump moves - A2 can evade in mid-air (see below) and jump a second time in mid-air: if she falls off a ledge rather than jumping, she can perform two jumps in the air. Holding the jump button causes A2 to grip onto the Pod to slow her descent. She also has two mid-air special moves: the first is a quick twirl which gains a small amount of additional height, which is performed by pressing light or heavy attack while gripping the Pod. Note that performing this move removes A2's ability to grip the Pod unless she performs one of her other air moves afterward. The second move has A2 use the Pod to slingshot herself forward, functioning like a second air evade: this is performed by pressing jump and Pod shot at the same time while in mid-air. Combining these moves is essential to reach some objects in the game.

Aerial Attack - Primary attacks in the air will keep A2 in the air as long as the combo lasts, which varies depending on the selected primary weapon while using a heavy attack will result in powerful downward strike. The power of the latter is enhanced by "Down-Attack Up" plug-in chips.

Heavy Attack - Basic heavy attack, does more damage, but is slower and has shorter combos. A heavy attack can be inserted as a finisher at any point in a light attack combo, with the type of heavy attack depending on the equipped primary and secondary weapons. Jumping and then immediately pressing heavy attack will perform a launcher move, with the precise move depending on the selected secondary weapon. Holding the heavy attack button with a spear or large sword set as the heavy attack weapon will charge a powerful attack, which has two levels, the second of which will have an extended attack if it connects. The latter is enhanced by "Charge Attack" plug-in chips.

Primary Attack - Basic light attack, does less damage, but is faster and has a higher combo potential. The precise nature of the attack depends on the equipped primary weapon: large weapons equipped as primary will still be slow. Holding down and releasing light attack does not perform a stronger short attack combo, as this control is instead used for A2's taunt move.

A2 is first encountered by 2B and 9S killing Immanuel. Pod 153 warns the pair that A2 is a wanted android and is recommended for annihilation. 9S questions the directive while 2B initiates a battle against the mysterious A2. Following A2's defeat, 9S asks her why she betrayed them. A2 mentions that Command was the one who betrayed them and escapes. 2B and 9S attempt to give chase but realize she's already gone.

After the defeat of Adam and Eve, when a corrupted 2B is being accosted by androids of YoRHa, A2 appears and disposes of her assailants. Realizing there's no hope for survival, 2B relegates her sword and memories to A2. A2 stabs 2B with her sword while 9S watches her take the sword out of 2B's bloodied corpse. 9S has a mental breakdown and angrily proclaims that he will kill the rogue android. A2 cuts her hair with 2B's sword in a style reminiscent of the deceased android. As he runs towards her, he falls off a bridge while gigantic pillars rise from the ground, forming the Tower. A2 is caught within the pillars' movements and is knocked unconscious.

A2 wakes up on a piece of debris with Pod 042 greeting her a good morning. A2 wonders about the Pod following her and is told that 2B's final order insisted that Pod 042 should assist A2. A2 scoffs at the notion of needing help and tells the Pod to shut up. After requesting her motives several times, A2 finally relents and tells the Pod that her goal is to destroy machines. He then directs her to the desert.

A2 arrives at the desert and encounters a Goliath-class Machine named Hegel. She defeats the machine and hacks into its mainframe, ultimately annihilating its core. A mirage of 2B appears to her and tells her that she and A2 are the same, with A2 angrily rejecting the notion by throwing her sword at where 2B appeared. After falling unconscious and reawaking, Pod informs A2 that her filter is full of sand and must be replaced. After heading to the Resistance Camp, A2 meets Pascal

A2 was part of the experimental YoRHa squadron deployed on the Pearl Harbor Descent Mission during the 14th Machine War.[5]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.

continued existence. However, her self-imposed mission of vengeance also serves as a means to distract her from her inner turmoil and regret as she privately longs to be with her dead comrades.

Pod 042 has also insinuated that A2's AI parameters are not to the standard of current YoRHa models, as she often requires him to simplify terms for her to understand.

A2 is initially depicted as mysterious and taciturn. However, it is eventually shown through her interactions with Pod 042 that she possesses a socially awkward personality and speaks in informal language. She has a propensity towards reckless behavior, as she will dive headlong into dangerous situations without consideration for strategic evaluations or her own personal safety. In the English audio, she tends to be more blunt, impatient, and foul-mouthed when speaking to others, almost resembling Kainé.

Just like 2B, A2 also has a hidden kind nature. She accepted 2B’s request to take care of the rest, and mercifully killed her before the logic virus deteriorated her mind. She eventually bonds with Pascal’s Village in spite of her virulent hatred for machines when she realizes that they are docile, like when she accepted the Machine Children’s request to play with her. She also went far enough to risk her life and desperately tried to protect the Machine Children in the Abandoned Factory. And when it turned out the Machine Children killed themselves after being consumed by fear, she expressed grief over them as well as sympathy for Pascal. She continuously spared and reached out to 9S, despite the latter's numerous attempts on her life, in the hopes that he could return to his kind-natured self. A2 can be ruthless and pragmatic, such as her act of killing a defenseless machine baby, Immanuel, in what was seemingly an act of vengeance, but in actuality a tactic to disorganize the Forest Kingdom’s army formation (as elaborated upon in the Short Story Long novel).

It is revealed in the Short Story Long novel that A2 (previously called Number Two) was a rather cheerful, naïve and somewhat incompetent android before the Pearl Harbor incident. It is also stated in "Beasts of Slaughter" that she absolutely abhorred violence and killing. After the death of her squadron, her hatred for machines and desire for their destruction become encompassing and define the rest of her

Due to her status as a deserter and a lack of maintenance, A2's attire can be classified as threadbare. The only clothing she technically wears is a velvet-like cloth around the midriff.

Large sections of A2's artificial skin are missing, revealing segments of the android's black protective undercoat.[6] The stripped layers are a rubber-like material and are most prevalent on A2's arms and legs, though pieces of skin are also missing from her torso and waist.[6] The exposed hypodermic areas resemble gloves, a sleeveless shirt, and hotpants with thigh-high boots.

A2's hair is long and wild, left to grow out within the years of her desertion. Her hair is cut short later on in Nier:Automata. A2 bears a strong resemblance to 2B, having pair of cold, light blue eyes and a beauty mark on the left side of her mouth.
