Harley Quinn was a pop psychologist turned supervillain over an infatuation with The Joker.
Harleen Quinzel hosted a talk show about love called "Heart to Heart with Harley." When the producers began doubting Harley's knowledge and the fact that she roasted Bruce Wayne on live television, they cancelled her show.
Joker, seeing the opportunity to take advantage of the woman, befriends her. Quinzel tries to do a psychological analysis of the Joker but the Joker is hesitant. When Quinzel earns Joker's respect, he suggests they have a night on the town. Harley is worried that she'll be seen with the Joker, so he gives her a red and black harlequin costume.
The two have a night on the town, killing squirrels in the park and throwing water balloons and squirting hoses at police officers. The next day, Quinzel notices that her talk show timespot has been given to a new talk show host. She gets Joker to help her attack the producers and this new host. However, the raid does not go as well as expected because Batman arrives and beats the two villains.
In the pandemonium, the building catches fire and Joker has to make a choice: save the unconscious Harley Quinn or make his escape. Joker chooses to escape and, when Quinn is captured by the police, the Joker leaves a whoopee cushion in the cop car telling Harley to keep smiling. Quinn forgives the Joker and the two share a laugh, her in the cop car and him somewhere else.
When the new vigilante Rumor attacks, Harley is abducted from jail and transported to the Rumor's own prison. When the Batman breaks out the villains, Harley Quinn and the Joker fight the hero but ultimately lose. They are both taken to jail this time alongside Rumor and the other villains.
In "The Metal Face of Comedy" Harley appears with Joker, Punch and Judy and Joker's new accomplice Marty Slacker. When Joker goes through an accident, nanobots replicate into Joker 2.0. Harley is skeptical about having a boyfriend made out of nanobots and is happy to see her real Joker return. Harley then starts to like Joker 2.0 more than the original Joker. However, when Joker 2.0 seemingly kills the original Joker, Batman and Robin Harley scolds him apparently "destroying her old puddin." when Joker is revealed to be alive Harley, Punch and Judy and Marty proceed to join the original Joker again. Joker 2.0 tries to kill them all but Batman stops him. The original Joker, Harley, Punch and Judy and Marty are captured by Robin and arrested while Joker 2.0 is sucked by into the game world and then killed off.
In "The End Of The Batman" Harley helps Joker steal a globe and the two manage to escape. Later in the episode she briefly appears again when she and Joker escape and drive off into the night after gassing Wrath and Scorn to stop them from revealing Batman's identity making her last appearance in the show.
