Black Heart's figure remains the same but her outfit reveals much of her skin. It is similar to her Orbital processor with the Angel processor color scheme. She has a white halo that extends in six directions, a pair of white double wings, a head necklace with a blue jewel, and two eggplant colored flower hairpins. Her attire is decorated with gold outlines and jewels that split between dark blue and sky blue.
Black Heart is a girl who thinks highly of herself and strives to be number one in everything she does, becoming quite competitive at times. Black Heart often does and say things but tries to play it off as if there is no more meaning behind her actions. It is possible that she is a very caring person at heart but masks it with snobby, arrogant attitude in the hopes people will not see through her facade.
