Ruby is a black eyed demon. She is a servant of Lucifer. As a human, she lived around the time of the plague, 1350. She sold her soul and after being totured in hell, she was being reborn a demon. She owns a demon killing knife.
The outfit is supposed to be a mix of what both 'Rubys' are wearing. It's more leaned towards the one at the top though.
In my opinion, I liked Katie Cassidy more in the role of Ruby. Genevieve (Padalecki now) is a great actres, she's really pretty and her and Jared makes an amazing couple, but the way that Katie potrayed the demon, was brilliant. When Katie was Ruby, the demon kicked more as.s
