Slick was hired by Harleen Quinzel to steal a truck full of military armor. During his attempt, something went wrong and he was captured by Detective Jesse Reese and his two colleagues. In the police station, he attempted to buy himself free by offering them $30 million, but they refused and spellbound him to a bench. They left to do paperwork and Slick transformed into water to escape through an air vent. Slick traveled through the pipes and appeared naked in Harleen Quinzel's shower while she was showering. She became mad, as Slick had been caught, hurting him by squeezing his testicles. She soon calmed down, deciding to give him one more chance.
Slicks went after the police officers, killing the first one by drowning him somewhere in the city, far away from any water. Some hours later he appeared in the police station as a puddle on the ground and followed the second officer. He turned back to his solid form, surprising her. Before she could do anything, Slick turned his arm and then the rest of his body into water to drown her within a few seconds. He flowed back to Harley, becoming solid in her office again when she wasn't watching. He asked why she is wasting her time as a therapist, with her replying that she loved to create chaos and fear, not expecting him to understand. She instructed him to kill the remaining cop from his arrest, in order for them to continue with their plan.
Slick flowed into the pool of the police station's gym that Reese was swimming in. He was talking to Helena Kyle, who was there to warn Reese about Slick. He attacked her after he realized that she knew about his abilities and tried to drown her. While he was wrapped around her body, she grabbed a fire-extinguisher and sprayed him. The cold substance forced his body to turn back to solid and they continued fighting with their fists. He soon realized that she was too strong for him when he was solid, jumping back into the pool to warm up and vanished. A few seconds later, he jumped out in liquid form and hunted Helena and Reese through the gym. Both hid in the sauna, while Slick followed them in solid form. He tried to enter the sauna as a puddle threw the door slot, but shied away because it was too hot for him inside and feared evaporation.
With no one to stop him, Slick stole the truck he had originally intended. He drove it to a warehouse where his henchmen were waiting to offload it. He jumped out of the truck along with the body of the driver he'd drowned, proudly saying that the truck is everything but not waterproof. Helena and Reese soon appeared, and his henchmen began fighting them. Reese attempted to punch Slick, but his fist went right through his liquid head. Using his liquid form to his advantage, he began to drown Reese. Suddenly, Dinah Lance appeared, helping an overwhelmed Helena by knocking out some henchmen. Overwhelming the remaining one, Helena grabbed a nearby flamethrower, boiling Slick to a puddle. Slick attempted to reform to his human shape, but remained a liquid. Unable to solidify while he was still boiling, Slick screamed in pain while turning into steam.
Powers and abilitiesEdit
- Liquid transformation: Slick had the ability to turn his entire body or just parts of it into water. This power was controlled by changing his body temperature. Warming up turned him liquid and cooling down turned him solid again. Extreme temperatures forced his body to transform. While in liquid form, Slick was in full control of his "body", able to form and shape into any possible form. His ability made him invulnerable and immune against any physical harm. He was able to get to any place water was able to get, flowing through pipes, holes, slits and vents, and passing every obstacle.
