Ash is a SimulacrumPilot and a minor antagonist in Titanfall 2. Once an elite Pilot, she was severely injured, and her mind was transferred to a robot body. She was subsequently hired by Kuben Blisk and joined the Apex Predators. As one of Blisk's top lieutenants, Ash was given command of an IMC battalion stationed at a testing facility on Typhon. When not on assignment for Blisk, Ash spent the majority of her time at the facilities creating new combat simulations, often using captured Militia soldiers as test subjects.
During the events of Titanfall 2, Ash is first seen combating Lastimosa in her customized Ronin Class Titan, drawing Lastimosa's attention away from Blisk as he took him out from behind.
During the Battle of Typhon, Ash was destroyed by BT-7274 and Jack Cooper. After the battle, Vinson Dynamics rebuilt Ash. Many of her memories were lost after she was rebuilt. She believes that her lost memories lie in the Remnant Fleet databanks. She currently leads Vinson Dynamics mercenary pilots in the multiplayer.
