Honkai Impact 3rd playable character.
Terminal Aide 0017 "Prometheus" was a Previous Era super AI created by Dr. MEI to predict and manage Honkai attacks. Its exact fate after the coming of Finality is unknown, although Mobius is recorded as having spoken to it shortly before that. The version relevant to the Current Era originates from a bubble universe, albeit one almost identical to the main universe.
Appearance-wise, it greatly resembles Bronya Zaychik, to the point that a certain character mistook it for Haxxor Bunny, but has red eyes and robot joints and lacks the crossed bangs. It is also voiced in Japanese by Asumi Kana, but with a robotic filter.
