Born on February 5th, 1993, Lisa Snart was the beloved sister of Leonard Snart and the alter-ego of Golden Glider, working together as members of The Rogues.
On the 13th of January 2013, after being captured by the One-Earth Regime, Wonder Woman publicly executed her. Her passing left Leonard full of resentment towards the Regime and its supporters, who actively cheered and celebrated her death.
Embittered by these traumatic events, he turned his back on The Rogues' no-killing code and joined Gorilla Grodd's Society, believing there was no point in honouring these rules when there were no Rogues left to abide by them.
Realising that Grodd was using The Society as puppets for Brainiac, Cold had a change of heart, concluding that Lisa would not want him to be responsible for mass destruction and genocide. Making amends with their former enemy, Barry Allen, aka The Flash, he collaborated with the Speedster to keep the streets of Central City free from crime. He hoped to honour her memory and make her proud of him.
