The alluring Lust dreams of becoming human. A desire so strong that she'll do just about anything to accomplish her goal. If anyone gets in her way, they are eliminated. She is even known to go against the orders of her creator. After all, homunculus have no soul. However, if she believes an alchemist is capable of producing the philosopher's stone, she will do her best to protect them.

Yes, Lust is a homunculus. Created by the elder brother of Scar. When she was alive, Lust and Scar's older sibling were lovers, but she died from a disease. The grieving man defied the teachings of Ishbal by learning alchemy. He attempted human transmutation and lost a part of his body in the process. (A vital piece needed for childbearing...get the picture?) He thought he was unsuccessful. Little did he know that someone would nurture his failed attempt with the red stone so that it may become.....a homunculus.
