In the brief history of Elise it seems that she made her living at a young age as an assassin of sorts (seen in the picture where she murdered a teacher for a fellow student). When her mother found out about what she was doing, Elise killed her as well.
Kimble is later approached by Clock King to join the Terror Titans and become the Persauder due to her legacy to be the ancestor to the Persuader of the 31st century.
Kimble is one of the more aggressive and vicious of the Terror Titans members as compared to the other members. She constantly pushes her limits with the team's leader, Dreadbolt. She killed off Molecule (the teen version of The Atom) against orders.
Elise showed her sensitive side when her father came to visit her. Unfortunately, it was short lived when Clock King murdered her daddy. After her father's death, Elise didn't much recover. She was very angry up until the metahumans in the Darkside Tournament were freed by Miss Martian. In order to avoid being attacked by them, Bolt teleported himself, the Disruptor, Elise, and Copperhead away to Clock King's lair. Once there, they were abandoned by Clock King and soon captured by the freed heroes. Two weeks after she was captured, Elise was freed by Bolt and Copperhead. The three of them formed a friendship and vowed to go after Clock King and end his life.
Legion of Doom
Kimble resurfaced as a member of Superboy-Prime's Legion of Doom. She was defeated by Ravager and Speedy.
