Welcome to your nightmare
Personality: Jinx is dark, deceptive with many interior motives. She will never show her motives to anyone. Jinx doesn't have much of a personality outside being cruel, viscous and unforgiving. She has a sharp tongue and is all business and no chat. The fact she takes on others fears and desires leaves her very little room to have a personality, but since part of her is still Light -- Light creatures consisted of Angels, Fae, and Elves -- she has a small pocket of empathy, but she represses it for the most part.
Fears: Jinx appears to be extremely fearless, she is everyone's worst nightmare. But, since she still has the part of her that is Light, or good, she almost causes fear of herself in the back of her mind.
Weaknesses: Those who can block her out, if one can block her out then sometimes those fake thoughts, or memories she is trying to push into that person's mind will bounce back. She also has the Light side in her, so this can come out at inconvenient times and cause much distress. She is also very new to the world, and doesn't know her own limits which can hinder her.
Strengths: She can easily penetrate into her victims mind and find their darkest fears, to their greatest desires and pretty much transform into whatever those things are.
Weapon of choice: Her own body, her ability to deceive humans, she uses mostly projectiles, but she is very good at hand to hand combat. She carries around a worn stuffed teddy bear. Her stuffed teddy bear is her spiritual guardian in disguise, since she is a new Demon in the world, those who created her decided to give her a guardian, her name is Medina.

Medina cannot help Jinx in battles, but she can give advice and talk her through things.
Past: Jinx was created by four demonic lords, four of the most powerful, many speculated about the Chaos Children being created, but no one actually believed they would be created. The Chaos Children -- Jinx and Echo -- were set out into the world for one simple purpose: Destroy the human race. And they will destroy anything and anyone that decides to get in her way.
