A manic and impulsive criminal from Zaun, Jinx lives to wreak havoc without care for the consequences. With an arsenal of deadly weapons, she unleashes the loudest blasts and brightest explosions to leave a trail of mayhem and panic in her wake. Jinx despises boredom and gleefully brings her own chaotic brand of pandemonium wherever she goes.
Jinx grew up in Zaun as an innocent girl who was good at tinkering with machinery and never quite fit in. However, a tragedy changed her into a completely different person who delighted in acts of destruction.
Jinx eventually became a widely known criminal, first gaining notoriety through her anonymous “pranks” on the citizens of Piltover, particularly those with connections to the wealthy merchant clans. These pranks ranged from mildly annoying to extremely dangerous, causing chaos and mayhem throughout Piltover and Zaun. Law enforcement attributed these to other gangs in Zaun, and Jinx was annoyed by this, deciding to make it clear that her future "pranks" were going to clearly mark her as their perpetrator from then on. Soon, word of her began to spread around and she became the most widely known criminal in Piltover and Zaun, causing mayhem and destruction wherever she went.
Jinx continues to cause mayhem around Piltover and Zaun wherever and whenever she can with seemingly no regard for the property damage or potential victims she would create, only occasionally being thwarted by enforcer Vi or the sheriff.
Jinx is a slender, sinewy, and light-skinned woman. She wears common punk street fashion typical for Zaunite youth. Her most noticeable features are her tattoos of stylized clouds, pink eyes, and natural blue hair.
Jinx is an eccentric inventor and criminal, taking pleasure in inventing and causing mayhem and destruction. She has become the most notorious and feared criminal in Zaun and Piltover, delighting in her criminal activities.
