Melanie is an hellborn from the greed ring, she is a demon shark Cyan and emo, she has a brother named Chaz that is taller but younger than her and is a complete idiot. 
Melanie has always to take Care of Chaz and always help him resolve the troubles hè gets in because of his reckless and pervy nature. 
Sometimes people think that Chaz is the older one because Melanie is friggin' short. 
Her parents are dead so Melanie has to do everything herself because Chaz is a lazy greedy idiot and a bitch.
