After a falling out with the Joker, she goes into a murderous frenzy, directed towards people responsible for the Joker's imprisonment. Captured by the Black Canary, she is forcibly inducted into the Suicide Squad by Amanda Waller. However, when she discovers that the Joker is rumored to be dead, it takes a further toll to her already-addled mind, and betraying the Suicide Squad, she puts their safety and secrecy at risk by turning herself into the Gotham Police Department in a plot to gain access to the skinned face of the Joker. Her plan apparently pays off and she manages to recover the face, though in a further psychotic episode, Harley captures and ties up Deadshot and places the skinned face of the Joker over Deadshot's face, so that she can carry on a "conversation" with her dead lover. Deadshot lures Harley in close, shooting and severely injuring her during the conversation. After the Joker returns to Gotham in the "Death of the Family" story line, he forces her to disguise herself in his old Red Hood costume and trick the Batman into coming to the chemical plant where they first met. The Batman then falls into a tank and demands Harley to tell him where the Joker is. But she only replies, in tears, that he is no longer the Joker she had fallen in love with.
