(Not Fully organized) Jessica Afton is the daughter of the blood thirsting, child murderer, William Afton, other known as Purple Guy himself.
When she was two, her father bossed a 'human' known as Yandress. He had the ability to 'grant wishes' but nobody could have the same, unless the holder of the power dies. William told him to give him the power of anonymous, to never figure out that he is the child murderer. He asked Yandress to give Jessica the same power, but couldn't. He gave Jessica a different power instead, the power to seek the future; there was a side-effect. Every time she looks in the future, she either broke, sprain, or bled. In three months, Yandress crafted a necklace for her; A dreamcatcher necklace. The main part, prevents her to have bad dreams, the right feather prevents her to have any injury or pain, the one on the left prevents her to ever see her first friend in her memories, her middle feather prevented to see ANY memory with Yandress in it, and lastly, a blue bead that connects the middle feather to the circle, gives her immortality.
At the age of 4, Jessica figured out that her father was the child murderer as she saw him slaughter a little boy in the Parts & Service Room with an ax. Many years of trying to keep her father's secret, she grew insane each and every day.
On November 27th, 1980, when Circus Baby's Pizza World finally opens, she had enough of keeping everything a secret. She wanted to show her father the pain all the other families felt when he stabbed the hearts out of the children. So, she went to the room that her father made the animatronic 'just for her' and stabbed herself in the chest, what she didn't know was, she only killed her insane side, which got her in a coma for 21 years.
