Mangle is the last model we get from the Dumpster diver. She is one who finds her looks very important (Think Roxy) she uses beauty as a coping mechanism do to her trauma from the bite

She is was Nessa's Childhood favorite model even tho she was not performing tapes of her were all over the internet (including the bite) 

Mangle is Smart and loves to make sure she is always Fabulous but deep down she is fear full of being scraped do to her past actions she is also besties with Toy Chica
