Violet was an employee at the Eternal Youth Spa.
Violet and Lily served under Poison Ivy during her operation of the Eternal Youth Spa. To the outside world, the girls appeared to be hosts, but in reality, they helped Ivy with her plan to turn wealthy but wicked industrialists into trees.
Though they were handy help against industrialists, Batman proved a tougher opponent. Violet was first to be bound, and Lilly shortly after.
