A derelict shopping center that has long since been abandoned and forgotten to time, the Gotham Mall is the replacement hideout that Harley Quinn and her crew took over after they were evicted from Ivy's apartment.
Long before the events of the series, Sy Borgman hid his sister, Mirielle Borgman in the basement of the old abandoned Gotham Mall to keep her safe after she was mutated into a Human-Octopus Hybrid. He kept her there in secret for many years always returning to feed her live goats. He also had a crematorium installed in a pizza oven and used the place to dispose of several bodies over the years including some of which that weren't dead yet.
When Sy found Harley Quinn, Poison Ivy, Doctor Psycho, Clayface and King Shark lying on the ground, seemingly dead and wearing 'Suicide Squad' shirts in Ivy's apartment he thought he had stumbled upon a suicide cult and decided to get dispose of the bodies. With help from former colleague Golda he moved the bodies to the Mall to have the cremated but they woke up just in time before they got burnt alive. As compensation for almost killing them, Sy agreed to gift the Mall to Harley as the new hideout for her crew in exchange for him getting to join in on some of their heists.
After Harley betrayed the crew by going back to the Joker and neglecting her crew members, they all quit the crew, thus leaving Harley and Sy as the solve residents of the Mall. However, they all ended up rejoining the crew in the finale after Harley earned back their trust and they returned to the mall.
However, they were ambushed by Penguin and Two-Face goons, claiming the mall was on their respective bosses territory. This inspired Harley to liberate the goons. The crew then used the mall as their base of operation while working to take down the Injustice League. After defeating the Riddler they took captive and used him to run on a hamster wheel, providing them with electricity.
After Doctor Psycho betrayed the crew and teamed up with Riddler, he started using the mall as his base where he controlled the parademon army, in an attempt to strike up a deal with Darkseid to rule the world. Doctor Psycho later managed to mind-control Ivy and forced her to battle Harley to death in front of them in the mall. Although, Harley eventually managed to loosen his grip on her and together they took him down. Psycho and Riddler were taken to Arkham Asylum.
After Harley and Ivy escaped from Commissioner Gordon, they safely returned to the mall as Harley sweeps off Ivy's feet and made love in a mattress store.
