-- The Joker src


Bianca Steeplechase was a ruthless gangster also known as the Joker. During the dynamic duo's final case, Bianca framed Bruce Wayne for the murder of Selina Kyle, and killed Robin with a fatal kiss (tongue was dabbed with poison). With Bruce on the run from the law, and Barbara in desperate need of a partner before she goes on the verge of a mental breakdown, they become a team, with Bruce donning the bat mantle. As for Bianca Steeplechase, she's dead. All there's left is Mrs. Gregory Wilson, the new wife of the mayor.

Powers and Abilities


  • Toxicology: Bianca has a penchant for poisoning her cosmetic products. She poisoned her nails and sliced at her enemies and even poisoned her lipstick to murder Robin.
  • Leadership: Bianca is a ruthless gang leader, coming up with schemes and plans to sew her influence and have her fun.
  • Singing: The night of Robin's murder, the Joker was singing to entertain a crowd of onlookers.



  • In Bianca's first on panel appearance she names herself as Blanca Steeplechase, a misspelling of Bianca.
  • Bianca is in a relationship with Harley Quinn, while Bianca is also married to the mayor of Gotham City under her alias. The Joker, a mysterious character with equally strange motives, is not tied down by regular rules and as such the nature of her relationships is open to question.
  • This is one of only two villainous Joker incarnations to be female instead of male, the only other being Martha Wayne.
