할리퀸 Harley Quinn S01E08 L.O.D.R.S.V.P.

After Harley's crew steal Atlantean jewels, they are invited to join the Legion of Doom. Luthor even allows Psycho to be reinstated so long as he does not fight any female superheroes. He secretly reveals to Ivy however that he is not actually interested in Harley and will not let her join unless she joins as well. Ivy refuses and tries to warn Harley of Luthor's treachery. Suddenly, Aquaman breaks into the Hall of Doom and beats up several villains while seeking revenge for Harley's theft, but she tricks him into breaking an aquarium and focus on saving the fish. As thanks, the Legion inducts Harley as an official member. Harley accuses Ivy of lying to her and they angrily part ways. Meanwhile, Psycho and Borgman deal with a mutant monster in their lair's basement. When Psycho tries to kill it, Borgman stops him; revealing it's his sister Mirielle, who got mutated because of him. Psycho uses his powers to let the siblings communicate and reconcile, but Mirielle is released into the streets and goes on a rampage. The next day, Harley and her crew minus Ivy go to the Hall of Doom, only to encounter Joker.
