When a group of surviving androids attacked the facility, 2B took her chance and broke out of her prison. Surprisingly, there were far less guards than she had anticipated, but 2B didn't let that dissuade her from escaping. It wasn't long before she made it to the ruins of the outside world.
Free from the grasp of the machines, 2B took a breather and began examining her heavily modified body. Despite everything that happened, 2B admitted that the machines had done a wonderful job in upgrading her. Her capabilities now far exceed a normal android, and she had gained the ability to adjust her physics at will. Curious, 2B soon started playing with her own body and soon had getting addicted to the feelings. However, she soon began subconsciously increasing the sensitivity of her body, ultimately resulting her OS getting overwhelm and got shut down.
When 2B woke up, she felt something had changed within her OS. Due to the shut down, the virus inside of her had partly merged with her OS, causing 2B's thoughts to become distorted. As the result, 2B became proud of her new modifications and power, but now, she desired even more. She soon tracked down a lone female android and ambushed her, grabbing her from behind. She then immediately began uploading the virus onto the android, causing her body to change and her clothes to disappear. The android trying desperately to break free, but 2B's strengths and the effects from the virus caused all her attempt to fail. Once she had been fully infected, 2B began upload her own OS into her minds, gradually overwriting her own and caused her body to change once more. When the upload was finished, the android had been transformed into a near perfect copy of 2B. However, she no longer had any thoughts of her own and 2B was now in control of her movements.
After a few practice, 2B had gotten used to controlling her doppelganger. Looking into the face of her double, 2B was satisfied with the results. However, her hunger for power could not be sated so easily, and she soon began plotted her next moves.
