"Lil' Miss Malachite" is the name of a gangster leader from Mistral. She and her followers have a spider theme. She is also the mother of the twins Melanie and Miltia featured in the "Yellow" Trailer. 
Lil' Miss is a heavy-set middle-aged woman with light skin and short blonde hair kept in a bob haircut. She has a spider in its web tattooed on her left shoulder, a beauty mark under her right eye, lipstick on her upper lip and purple nail polish on her fingernails. The top of her dress is white and backless, with long sleeves and details, such as beads and straps, in purple. Below is a purple corset, and a long pleated skirt that is yellow on its top layer, purple in the middle one, and white in the lower layer. Her shoes are brown and decorated with a green ribbon.
From what is known from her initial appearance, Lil' Miss is quite efficient in running her organization despite fearing spiders in her early years. She does not allow anyone to approach her unless for business purposes, and she makes her displeasure known if she finds someone acting impetuously as Cinder Fall finds out upon meeting her.
She is also very cunning and devious, keeping Cinder in the dark about information she has on hand in hopes of doing business with anyone seeking Cinder herself.
