Arkham Sirens

The Gotham Sirens conducting a mission

The Gotham Sirens or Gotham Girls are a group of female villains consisting of Poison Ivy, Harley Quinn and Catwoman. They have worked together in the past in order to commit crimes but over the years, the group slowly separated and became less reliable as each member became more preoccupied with their own motivations:

  • Harley Quinn became more preoccupied by the Joker and his schemes which Catwoman and Poison Ivy strongly disliked.
  • Catwoman sided with Batman more often which made her untrustworthy to Harley Quinn and Poison Ivy.
  • Poison Ivy became more preoccupied with the welfare of her plants rather than humans so she increasingly distanced herself from Harley Quinn and Catwoman.

Despite these differences, the Gotham City Sirens would still support each other as friends, particularly Harley and Ivy.

Arkham Origins Incident[]

During the events on Christmas Eve, Dr Harleen Quinzel was a trainee psychiatrist who interviewed the Joker for a psychological report. Selina Kyle was an unknown criminal during this time and Dr Pamela Lillian Isley was working for GothCorp.

Formation of the Gotham Sirens[]

After the events of Batman: Arkham Origins, Harley Quinn fell in love with the Joker and assumed her own criminal identity and Poison Ivy was poisoned by Jason Woodrue leading to her transformation. Selina Kyle began theming her crimes around cats and named herself as the master thief, Catwoman. At some point, the three villains met and befriended each other, realizing the potential success of their crimes if they worked together. This led to the inevitable formation of the female trio known as the Gotham City Sirens.

Criminal Career[]

While Catwoman enjoyed the team-up with Harley and Ivy, she secretly felt the partnership was doomed to end. Eventually, Harley and Ivy felt that Catwoman's relationship with Batman was the catalyst for the break-up.

Arkham Asylum Incident[]

During the Joker's takeover of Arkham Island, Harley Quinn met Poison Ivy in her cell in the Penitentiary. Ivy begged Harley to be let free, as she sensed her "babies" were in danger. Harley seemed reluctant, since Ivy was not on Joker's party list, but gave in due to their friendship. Ivy was set free and made her way to the Botanical Gardens. Harley was later defeated by Batman and locked away. Ivy became was infected by TITAN, which caused her plants to destroy Arkham Island. Shortly thereafter, however, she was defeated by Batman as well and sent back to her cell. Catwoman was not present on the island, presumably having escaped prior to the Joker's return.

Before Arkham City[]

After the Arkham Asylum incident, Harley Quinn's primary focus was treating the Joker so she had no contact with her fellow Sirens during this time. She and her "Puddin'" escaped their cells and stole a boat which ended up in Arkham City. They made the Sionis Steel Mill their hideout and enacted their schemes from there.

After surviving the effects of TITAN, an enraged Warden Sharp sent Poison Ivy to Arkham City. Catwoman, however, rescued her from the TYGER guards, allowing Ivy to kill the guards in revenge. She then dropped Ivy off at Gotham Park, with Ivy making her promise to water her plants.

Catwoman later went to Sharp's office at the asylum to take Two-Face's pictures of the blueprints of Arkham City. When TYGER guards burst into the room, Catwoman was pulled to safety by Batman. However, when she noticed the card of Two-Face's camera was missing, she looked down and saw Two-Face swallow it. Furious, Catwoman jumped down and knocked Two-Face to the floor, before being surrounded by TYGER guards. She was then taken to Arkham City.

Arkham City Incident[]

During the events of Arkham City, Harley remained separated from the other Sirens as she was too busy looking after the terminally ill Joker.

Meanwhile, Catwoman decided to call in Ivy's help when she needed a way to enter the Confiscated Goods Vault with a "woman's touch". Upon meeting her, an angered Ivy entangled Catwoman with her plants and was tempted to kill her for not looking after Ivy's plants. When she explained this to Catwoman, though, the latter proposed to get Ivy's plant if she could help her into the vault. Ivy reluctantly agreed and helped Catwoman into the vault.

Inside the vault, Catwoman came across Ivy's plant, though she killed it as revenge for Ivy tying her up in her plants. When she returned to talk to Ivy, she blamed the death of the plant on Hugo Strange.

After Arkham City Incident[]

After retrieving her stolen goods from Two-Face, the activities of the trio was largely unknown. Harley escaped custody and returned to the Steel Mill, plotting her revenge against Batman for supposedly killing the Joker.

Later, Harley Quinn broke Poison Ivy out of Bludhaven. However, she was ambushed by Nightwing who was taken down by Poison Ivy's plants.

Arkham Knight Incident[]

When Scarecrow returned to Gotham City with a plan to destroy the Batman, he recruited some of the Dark Knight's most dangerous villains, including Harley. Ivy refused, having decided that she would now permanently distance herself from humanity. This angered Scarecrow and led to her being locked up inside a safe house in the Chinatown district of Gotham where Batman eventually saved her. He then brought her to GCPD Lockup, but later needed her help in ridding Gotham of Scarecrow's Fear Toxin. She aided him voluntarily and successfully saved Gotham, albeit with the apparent cost of her own life.

Harley, meanwhile, attacked a quarantine zone Batman and Robin had set up to attempt to cure the "Joker Disease" which affected five people. While Harley managed to override Batman's security and free the "Joker clones", she and the clones were eventually caught by the Dynamic Duo and Harley was locked up in one of the quarantine cells.

Catwoman was not involved in the night's events, as she was inside the Pinkney Orphanage, being held captive by the Riddler. She wore a special necklace, which required nine keys to unlock and would cause her head to explode if she chose the wrong key. She was eventually rescued by Batman and aided him in taking down the Riddler, before heading off into the night.

After Arkham Knight Incident[]

When Batman and the GCPD reclaimed control over the city, Harley was presumably arrested and taken into custody.

On the place where Ivy lost her life, a flower started growing - a small memorial for what she did for Gotham.


  • Both Harley Quinn and Catwoman call Poison Ivy "Red", due to her hair color.
  • All three sirens named each other mostly by their criminal name (or part of it). The only exception to this is Catwoman, who Harley and Ivy usually call Selina.
  • Never in the Arkham games have the Gotham Sirens worked together as a trio. However, they have in the Arkham Unhinged comic book series.
  • Ironically, Ivy died saving many people, even though she said that she would destroy every so-called "meat sack" on the planet.
  • Interestingly, all three members have at one point in time assisted Gotham during a crisis. Harley Quinn assisted the GCPD during the Arkham Origins incident when performing a psychiatric evaluation on the Joker, Catwoman occasionally assisted Batman in his endeavors and Ivy assisted Batman in stopping Scarecrow from spreading his Fear Toxin across Gotham City.
  • It is unknown how Harley and Catwoman reacted to Ivy's passing.
