Aw, such sweet girls.
— Mrs. Cobblepot[src]

Mrs. Cobblepot is the sister of Oswald Cobblepot (better known as the Penguin), and is the mother of Joshua Cobblepot.

Like the rest of her family, she appears to be involved in a life of organized crime, or at the very least, is aware of their activities and accepts their decisions as she was perfectly happy with her son getting involved with the Legion of Doom.


In "A High Bar" Mrs. Cobblepot held the bar Bar Mitzvah for her son Joshua at the Gotham Mint although it appeared she left much of the planning to her brother, The Penguin who invited many of Gotham's high-profile villains and used this to introduce him to a life of villainy.

At the party, she approached Harley Quinn and Poison Ivy, asking them to think about their bad language due to the children present which they smiled and agreed to. Later, as Joshua was unable to pull the trigger on Harley, who had ruined the fake-robbery the Penguin had set up for him to perform, after she mocked him, he ran into his mother's arms crying. She then angrily told Penguin that "I told you we should have gotten him the dollhouse that he asked, Oswald". She later watched as the Joker was called out for his poor treatment of his colleagues and was shocked when Bane revealed he "didn't even want to come to this stupid thing". As Harley and Ivy left the party, she gave them each a bag of money as party favors, commenting how sweet they were.

In "Finding Mr. Right" she was watching the Tawny Young show with the Penguin and Joshua when Harley and Ivy were fighting Batman live on-air.

In "L.O.D.R.S.V.P.", she appeared as a guest at the Legion of Doom's prospective member night at the Hall of Doom alongside her brother.


Mrs. Cobblepot appears to exhibit extreme signs of being a Stepford Smiler always acting bright and friendly to everyone she meets, speaking in polite happy tones, and acting like everyone's mother. She appeared to have no problem with playing host to ruthless criminals at her son's Bar mitzva, implying that she might be a lot tougher than she looks.

Unlike her brother and son who both hold a large grudge against Ivy and Harley for ruining her son's Bar Mitzva, she appeared to actually enjoy all the chaos they caused and still gave them each a gift bag before they left.

Episode Appearances[]


  • Both Harley and Ivy enjoy mimicking her friendly tone whenever they speak to her, presumably as a form of mockery, although they might also genuinely like her.
  • In the comics Oswald Cobblepot never had a sister but in the television show Gotham he has a step-sister named Sasha Van Dahl.
