From the Free Radical Design (RIP) FPS series TimeSplitters, it's robotic semi-protagonist Gretel. Sourced from around 50 images consisting of screengrabs from each game in the series, concept art, and what minimal key art exists of the character(s).
0.7 - 0.9 weight plays nicest. lower than this tends to generate more human-like features
helper tags: feminine robot, mecha, robot joints, white eyes, bald, mouthless* (see note)
seems to be fairly permissive with regards to types of metal you can make her skin. i like brushed steel and polished chrome myself
*note: highest recommendation for the "mouthless" lora in the "suggested resources" section to discourage mouth/nose generation
outfit:
for mk2: hood, cloak, red gloves
for mk3: white "13" hoodie, track pants, sneakers, short red gloves
recommend adding hair to negative to discourage her hood being interpreted as a weird bob haircut
