Reference sheet for Belatrix, done by  oli_snowpaw. Belatrix is a Clydesdale Unicorn.

She is a tough lady who takes any task requested of her very seriously. Her draft horse instincts can cause her to become completely focused on a given task and make her become very annoyed at any distractions. However, when she is not working, she is a friendly person to be around. Though she doesn't have much of a sense of humor she still enjoys being around others. This dichotomy of dead serious vs easygoing personality has resulted in her having the nickname "Sweet-N-Sour".

Her occupation is that of an airplane mechanic at the local airport. The seriousness of making sure airplane maintenance is done right fits well with her personality. She loves taking advantage of her Clydesdale strength at every opportunity, not so much to show off, but because she enjoys it.

Note about her featherings. The hair on her featherings, head, and tail grows white from the root and then turns purple partway to the tip. So what color is where depends on how gravity/wind/etc is pulling the hair. Arms at her side, the purple will be by her wrists. Arms above her head, the purple will be by her elbows.
