Weiss had fallen under the powers of a Grimm known as nightmare that corrupted and transformed her into “Negative Weiss”. Becoming a cold, stoic, fascistic version of herself. Fearing Faunus, but still caring for her teammates, even having conflicting feelings towards Blake due to Blake being a Faunus herself. Now Weiss believes herself to be a military commander that protects her version of Atlas in her dreams, her Kingdom.

Her attire changed as well after being transformed. Negative Weiss was identical to the real Weiss except she lacked a scar on her left eye, wore her ponytail center and paler skin. She wore an Atlas Military uniform that consisted of a skin-fitted short sleeveless white dress that fastened on the right side, with a hexagonal cut out on the bust alongside several black straps. She had a white short cape that is attached to the dress. She also wore a grey mesh top underneath that has a black snowflake styled design visible through the dress' cutout and the mesh sleeves were mostly covered with white sleeves that had a black strap on the trim. Weiss also sported a flowing white trench coat cape decorated with various black thorn-like and snowflake designs which she wore draped over her shoulders, light gray tights, and white high-heel pumps. In addition, she carried around sky blue sunglasses and wore a white kepi with black visor on her head.

Weiss: This world needs protection from the Faunus, from all sorts of evil. I will protect this place… my home, my family that I care for, my people, my kingdom… Everything will be protected with myself making sure of it. She says as soldiers march behind her as Weiss puts on a pair of sky blue sunglasses
