The obscure Rebecca from Murder Drones

I wouldn't blame you if you forgot about this character's existence, even though she has a cute design.

Prompts: RebeccaMD, 1girl, solo, robotic, dark blue hair, blue eyes, mask, helmet, tied shirt, skirt, colored sclera, short hair, black boots.
Negative prompts: blurry, lowres, bad quality, text, watermark, human, nose, background characters, multiple characters, ears.
Other useful prompts: metallic limbs (or metallic arms + metallic legs), striped limbs, white hands, white neck, choker, chest mark, black girdle/corset, mini skirt or short skirt (if the outfit is too long), no human + no nose (if negative prompts are not enough).

Side Note: This model was trained with images from her camp outfit (blue shirt and skirt) as well as her cheerleader outfit (red skirt and top). This means you can probably get the outfit you want if you adjust the prompts.
