Miss Belial fpe

Taking the image as a reference and maintaining the essence of Belial from FPE, a female version could be described as follows:

Face: Her skin would remain bluish-gray, and she would have a serious, cold, and indifferent expression. Her eyes would still be red, with a tired or narrowed gaze that conveys superiority and little emotion.

Hair: Long and thick, parted in two colors: black on one side and bright red on the other. The bangs partially cover one eye, giving her a mysterious look.

Horns: Large, curved, and bright red, similar to the original design, sticking out from the hair.

Build: More slender and with a feminine silhouette, but without losing the character's intimidating presence. The posture would be relaxed, with slightly slumped shoulders and hands in pockets or at the sides.

Clothing: A fitted black turtleneck sweater, high-waisted black trousers, and a simple belt. All in dark tones to maintain Belial's understated aesthetic.

Colors: Black and red would predominate in the hair and horns, combined with bluish skin and completely black clothing.

Personality reflected in the design: Even in a female version, she would still appear distant, proud, and difficult to impress. Her expression would barely change, giving the impression that she is always judging those around her.

Overall, she would look like an elegant and intimidating female version of Belial, retaining all the character's iconic features (two-toned hair, horns, bluish skin and cold attitude), but with a more feminine figure and features.
