"I'm just a desperate cop that got backed into too tight a corner."
—Liza to Quentin Lance[src]

Liza Victoria Warner is a police sergeant of the Star City Police Department, and the leader of the Rogue Task Force.


Early life

Liza Warner studied Forensic Criminology at Starling University.[1]

The Task Force

In 2012 she was one of the original recruits for the specialized Anti-Vigilante Task Force. The Task force was created to hunt down the unknown vigilante archer known as the Hood.[1]

In 2014 Quentin Lance was promoted to Captain and disbanded the taskforce as he deemed it was no longer necessary to hunt down the vigilante now known as the Arrow.[2][1]

When (an impostor dressed as) the Arrow killed Mayor Celia Castle the Task Force was reinstated again and a huge manhunt for the Arrow began.[3][1]

Going rogue

In 2015 she and five of her teammates decided to go rogue. They began to target drug dealers and other criminals. Killing them and stealing their merchandise, which they would then sell to other criminals. By this way they wanted to make enormous amount of money and then flee the city which they believed was beyond saving. After one heist two SCPD detectives showed up who were surprised by their presence as they had not called a SWAT team in. Liza quickly drew her firearm and shot them both. One of the detectives managed to shoot her in the vest which made her lose a phone. She quickly killed him and fled the scene but left the walkie talkie behind.[1]

The Rogue force learned that Thea Queen was going to buy a huge amount of drugs. They closed in on them but got ambushed by Black Canary and Green Arrow. During the fight her team defeated Diggle and Thea. Liza engaged Black Canary in single combat and quickly defeated her. She blocked the arrows shot by Green Arrow but took one in the vest. Liza and her team took the drugs and quickly fled the scene. While fleeing the scene Liza noticed Captain Lance was part of the group that had ambushed them.[1]

The group confirmed the drugs were real and some members wanted to kill Captain Quentin as he was a risk. Liza drew her firearm and told them they were not criminals and they would not kill cops. She offered a solution in which they would use Lance to their advantage.[1]

The group tracked Lance down to a building and captured him. His daughter Laurel Lance came to his aid but they quickly tassed her and left.[1]

They brought Captain Lance to the SCPD disposal facility and used his fingerprints to get in. Captain Quentin called her a criminal but Liza said she was simply a desperate cop backed in a corner.[1]

After loading in the drugs she cuffed Captain Quentin who told her to kill him as he would hunt them down with everything he had. Liza replied that they will leave the city. Team Arrow attacked them again. Green Arrow confronted Liza. She blocked a shot but got ensnared with a trick arrow. As Green Arrow freed Captain Quentin she cut herself loose. She blindsided Green Arrow and threw a knife in his back after which she started to strangle him with the wire of the trick arrow. Keeping him hostage she told Quentin she would cut his spinal cord. Captain Quentin gave a speech and told her that they were all desperate and doing all desperate things. In order to save their home they would have to save themself first. He reminded her that she had put on that uniform as she had believed in justice just like he had. Touched by his speech she let go of Green Arrow and allowed herself to be arrested by Captain Quentin.[1]

Leading a crusade

During her time at Iron Heights Liza witnessed Quentin confession of working with Damien Darhk, this caused her to become disillusioned leading her to ally herself with Carrie Cutter and China White. They then broke out of the prison bus they were on in order to locate money left behind by Tobias Church after his death. The three of them first hit the Chinese Triad, leading to a massacre. They then targeted the Bertinelli crime family only this time the Green Arrow and Quentin intervened, leading to Liza being shot with an arrow and fleeing the scene. Though not before being confronted by Quentin about her return to crime, angrily telling him it was because of his previous ties to Darhk. After interrogating more gangsters about the money's location Liza hired more gangsters in order to get away with the money. Arriving at the location the three of them were about to escape before the arrival of Team Arrow and Quentin stopped them. After a brief sparring match with them Liza called upon her gang members to fight the vigilantes. During this fight she managed to beat Curtis Holt before the arrival of the ACU stopped her from getting away. She was then arrested and taken to the precinct where she had one final talk with Quentin before being sent back to prison.[4]


Liza Warner is highly driven to be a cop and serve justice. However, as during the years the city started to wear down, she slowly lost her faith. This caused her and her partners to go rogue and serve themselves. 

Even while killing criminals and stealing she still believed herself to be a cop and tried to avoid killing cops or civilians. Captain Quentin Lance reminded her of her beliefs and that they had to work together for the greater good. Touched by his speech she surrendered.
