Ladybug's Darkside

Marinette snaps after so much abuse from her peers and her parents throwing her out on the streets, she's still every Parisian's favorite hero by day, but to feel safe and pay for everything she needs to survive she has turned to illegal underground fighting matches. She has worked her way up to the top where every match she fights is no holds barred, meaning no rules against anything, even killing and weapons are allowed. Her changes don't go unnoticed by those around her, but nobody cares enough to ask if she's alright, instead of caring they just laugh at her and poke more fun at her fueling her anger.

Chloe and Zoe are full blood sisters in this.
