"Do you cuties need some counseling? I'm a trained therapist."
—Harley Quinn to John Diggle and Lyla Michaels[src]

Harley Quinn was a rejected member of the Suicide Squad. She had been deemed too deranged to be trusted on the Suicide Squad's mission to appropriate the nerve agent from Gholem Qadir in Markovia.[1]


While John Diggle and Lyla Michaels were arguing outside of A.R.G.U.S. holding cells, Harley Quinn offered to help them through their problems, claiming she was a trained therapist. Amanda Waller then hit her door to silence her.[1]

Behind the scenes

"I want to manage expectations with respect to Harley Quinn. She was always intended to be an Easter egg. I don’t want people to go in with incorrect expectations and walk away from Episode 16 disappointed. But there is an element to the Easter egg that was not spoiled by the promo, that I think people will find a lot of fun."
Marc Guggenheim[src]
  • Producer Marc Guggenheim admitted that although the character was indeed Harley Quinn, a long-time enemy of Batman, the character was simply an easter egg for fans and was instead credited as "Deranged Woman" in the end credits of "Suicide Squad".
  • Harley is voiced by Tara Strong, who uses the same voice she uses for Harley Quinn in various DC properties since 2011.
  • In the 2011 rebooted comic incarnation of the Suicide Squad, Harley Quinn appears as a member.
  • According to Stephen Amell, Harley was planned to appear in the Season 2 finale, "Unthinkable" but the scene was cut due to time.[citation needed]
