Raven is a dark and troubled character, being half demon. Her power is drawn from her infernal side but when she loses control of her emotions, her demonic heritage takes over. She is a magical super-hero that uses powers such as telekinesis, telepathic and empathetic magics and dark energy. Raven is usually dressed in the colour of her name-sake, blue-black and adorned with red gemstones in gold fixings. Her iconic hooded-cloak is pointed, reminiscent of a bird's beak.
After further researching Raven, also known as Rachel Roth, I discovered a past fraught with conflicts with her infernal family and her own dark side. She has been host to her father, Trigon on more than one occasion and fought on both sides of the good/evil divide. Her darker manifestations show her with her father's 4 eyes, pointed ears, teeth and claws and sometimes red skin but the most common appearance change due to her power seems to be glowing eyes. Her forehead is adorned with a red gem known as a chakra, bestowed upon her by her pacifist mentor to help control her dark side. Raven's outfit was changed to white at one point to signify her victory over her father's influence and she is also sometimes coloured with black and purple or black and red, unlike her traditional costume. Fan art and cos- play often provide inspiring variations on a character while maintaining what they consider to be iconic or fixed features.
