Mona "Delilah" Lanius grew up in a very privileged and lavish lifestyle, her parents being insanely rich as they are the inheritors of a pharmaceutical empire. Living together in a literal mansion and in a mostly white, gated community no less. She had a relatively average childhood, her parents, although having a tendency to be distant due to working all the time, were supportive of Mona and gave her absolutely anything she could ask for.

Mona lived as a recluse however due to her deformities and an extreme sensitivity towards sunlight that forced her to stay inside at all times, usually cooped up in her bedroom, painting and drawing the day away, having exhibited great artistic talent at a very young age which her parents encouraged.

Mona's unusual appearance is due to the fact that she's a product of incest, the Lanius family having practiced inbreeding for generations, believing in a false notion of keeping it within the family in order to keep their bloodline "pure" and while Mona's parents looked completely normal they were emotionally and mentally stunted and had a lot of health problems that they mitigated with their practically limitless access to drugs.

Mona meanwhile is the complete opposite as she is extremely intelligent and has superb health but is heavily deformed. Her deformities include full body vitiligo, extreme photophobia (a skin condition identified by an allergy towards sunlight), Marfan Syndrome (longer than average limbs) in her arms, legs and fingers, extreme ocular albinism resulting in her black colored irises and silver pupils, as well as larger than average eyes, a minor cleft lip and Kyphosis (hunched back).

On top of being a budding, talented painter, Mona has many other skills and talents that she acquired through her rich parents encouraging to take up as many hobbies as possible in an effort to make her more "cultured" and make up for her physical appearance. These hobbies included sculpting, photography, sewing, gymnastics, hunting (as well as cutting and dressing meat) and musical talents with the violin and piano as well. Her high intelligence allows her to pick up on things quite fast.

Although having a love for art, Mona had aspirations of being a surgeon when she grows up, having a lifelong fascination with organs and blood even at a young age but also having a strong desire of being appreciated and accepted by others in spite of the way she looked. Mona would spend her days reading medical books and "practicing" on her stuffed animals, tearing them apart and stitching them back together.

Mona also developed a fascination with drugs and narcotics and the effects they have on people and would sometimes experiment with them by slipping one of dozens of substances she could easily gain access to due to the nature of her parent's career into the drinks of house guests or friends of her parents, doing so not out of malice but because she was a curious child who didn't know better.

It also didn't help that her parents didn't do much in teaching young Mona about morals or boundaries and although Mona was an intelligent, shy and even gentle child who wouldn't hurt a fly if she could help it, Mona would end up doing a lot of questionable things during her informative years such as taking roadkill into the house and pretending they were her pets and breaking into people's homes in the dead of night out of curiosity of how they lived.

Young Mona became something of an urban legend in her community due to her appearance and reclusive nature, people who would see glimpses of her from her bedroom window believed she was a ghost due to her chalk white skin and dark hair. Even her parents rarely acknowledged her in a public light, no one outside of the gated community they lived in even knew of Mona's existence.

The neighborhood children would throw rocks at Mona's window while the braver ones would even try to break in and get a good look at her, those who did were either frightened or would mock her relentlessly, calling her a "monster" or "freak girl", breaking her beautiful paintings and even physically assaulting her, such as pulling her hair.

The worst thing these brats have done was force her out of her home during the day after becoming aware of her sensitivity towards light, the harsh rays of the sun caused Mona's skin to literally boil, causing her to scream and cry from the worst pain imaginable as she began to smell like burnt sausage.

It took months for the the burns to properly heal.

Severe social detachment, relentless bullying from purebred white kids and living with a distant and equally vapid and egotistical family who secretly resented the way she looked would all culminate in Mona becoming extremely resentful and emotionally detached from people to the point where she began to view the world and humanity as a whole as just "ugly and wrong", which would play into her complete lack of empathy and morals as an adult, as well as her motives as a serial killer.

By the time she was thirteen years old, Mona held a vehement, deep-seated hatred for people, every person she ever came across at this point hated her for just existing when she did nothing to them. The only human beings she didn't feel this way towards was her parents, who she loved very much and deemed them as the only good people in her life and possibly the world… until one fateful night.

The tipping point for Mona would come when she secretly listened onto a conversation between her mother and father while they were shitfaced drunk, mocking their daughter and relentlessly criticizing the way she looked, calling her a disappointment and even a "freak". Mona was immeasurably heartbroken at the words that her own parents, the only human beings she thought actually loved and cared about her have said.

Something inside Mona had finally snapped.

In a rage, Mona murdered her parents with an axe, relentlessly hacking away at their bodies long after they died in a hellish fury of blind rage, her screams of rage and despondent cries were suddenly turned into maniacal laughter that contrasted the streaks of her tears pouring from her black eyes.

Mona, now completely covered in the blood of her parents, lied on the floor with her bloody hands covering her face as she struggled to catch her breath, a whirlpool of powerful, conflicting emotions and thoughts scrambled her brain. She then looked upon the chopped up pieces of her hacked up parents and in the scattered gore she felt an overwhelming sense of inspiration in the gory display. She retrieved a needle, lots of thread, paint and a canvas from her room.

Mona stitched together the many scattered limbs and pieces of her mother and father together in a two-headed, frankensteinian doll and then painted an abstract depiction of this monstrosity on her canvas, titling it "Mother and Father".

Mona was in awe of the works of art she created, she took something as ugly as her vapid parents and turned them into something that was, in her mind, beautiful and worthwhile. Her tears, once of profound hurt and sadness, become tears of joy as she gazed upon the beauty of her creations.

Mona has found her calling, she has decided that she will use her talents as an artist to twist the ugliness of the world around her into beautiful works of art, maiming, butchering and gutting her victims and then immortalizing them in her paintings, capturing the beauty of her murders and the pain she inflicts forever. After burning down her house with her parents remains inside, Mona took nothing but the clothes on her back, some cash from the family vault and a few art supplies and jumped the gates of her neighborhood, disappearing into the night.

It was at this moment, that the most infamous serial killer in American history was born.
