Two months before joining Young Justice, Jinny was a regular girl in Dripping Springs, Texas. After seeing her girlfriend having fun with another girl, Jinny storms off and accidentally walks into a robbery at a local bowling alley. Taking control of the situation, Jinny disarms the robbers and stops them before they can get away. She returns to her house, where her mother shows her the trunk that was owned by Jinny's great-great-grandfather, Jonah Hex, full of things that he had collected over the years. She would later use these artifacts in her own superhero career.
- Jonah Hex's Trunk: The items gathered inside this trunk by her ancestor grant its possessor a set of powers. These items include:
- Prior to joining Young Justice, she had a girlfriend with whom she broke up after catching her having fun with another girl.
