It’s Harley Quinn season. She’s become a mega draw for Hollywood and a huge part of the DC fandom, mostly because of Margot Robbie’s portrayal of the character in “The Suicide Squad” (the 2021 version, let’s forget about the original, shall we?) and “Birds of Prey.”

But Harley Quinn has been an integral part of the DC universe since her introduction in the now legendary “Batman: The Animated Series.”

In fact, she’s quickly become an absolute fan favorite, taking part in multiple DC projects. However, despite her growing fame, it wasn’t until 2019 that she finally deserved her standalone TV project – the “Harley Quinn” animated series.

This Harley Quinn animated series follows the character as she tries to step out of the Joker’s shadow and make a name for herself. In this article, we’ll clue you in on what you can expect from this racy and critically acclaimed cartoon series and who some of the people behind the scenes are. 

And as season 3 just had its premiere on HBO Max, now is the right time to catch up with what you might’ve missed by not watching this amazing adult-animated series set in Gotham city.

About DC’s “Harley Quinn” TV Series

Unlike TV shows like “Justice League” and “Batman: The Animated Series,” the ultra-violent and raunchy “Harley Quinn” is not meant for children. After Quinn’s boyfriend, the Joker, escapes a fight with Batman and leaves her behind to fend for herself, she realizes the clown will never see her as an equal. She decides to make a clean break from the Joker and sets out to become a respected criminal overlord. 

Her goal is to join the Legion of Doom alongside esteemed villains like Lex Luther, the Penguin, and of course, the Joker. Harley decides to put together a ragtag team of other villains you may recognize from the Batman universe, like King Shark, Sy Borgman, Clayface, Doctor Psycho, and Poison Ivy, to wreak havoc in Gotham City.  

Of course, becoming a Gotham City crime overlord isn’t the easiest thing, and the adult-animated series follows Harley as she struggles to achieve her goals, often finding herself in hilarious situations.

The first season of the series started airing in 2019 on DC Universe to critical acclaim, with critics praising the show for its humor, animation, dark tone, and voice acting, especially the performance of the leading voice actress – Kaley Cuoco.

The series became an instant success, with the second season premiering a year later in April 2020. The show was officially renewed for the third season in September of the same year, moving to HBO Max due to the restructuring of DC Universe.

Season 3 had its American premiere on July 28, 2022, and is available on HBO Max along with the first two seasons.

Who Are the Executive Producers of DC’s “Harley Quinn” Series?

DC’s “Harley Quinn” is a Warner Bros. franchise. The show was developed by executive producers Justin Halpern, Patrick Schumacker, and Dean Lorey. The group has a lot of experience writing in the comedy sphere.

  • Justin Halpern is also a well-known comedy writer. He’s the author of the best-selling book “Sh*t My Dad Says” which was turned into a sitcom starring William Shatner (which Halpern also wrote for). 
  • Patrick Schumacker is a producer and writer who has worked on several comedy shows like “Cougar Town,” “iZombie,” and “Surviving Jack.” The latter was also based on a book by Halpern (“I Suck at Girls”).  
  • Dean Lorey has written for and produced some hilarious comedy shows like “Arrested Development” and “My Wife and Kids.”

This isn’t the first time the trio has worked on a DC series together. The team was also behind a short-lived DC sitcom that ran on NBC in 2017 called “Powerless.” Like “Harley Quinn,” the live-action show was a subversive superhero comedy. 

It followed a group of engineers within the DC universe as they tried to make products to protect normal humans from superhero battles. The show starred Vanessa Hudgens, as well as a few actors who would eventually do voices on “Harley Quinn,” like Ron Funches and Alan Tudyk. Unfortunately, the comedy was canceled midway through its first season. 

Who Are the Main Characters of “Harley Quinn”?

The main characters of “Harley Quinn” include:

Harley Quinn:

DC Harley Quinn - Kaley Cuoco

Dr. Harleen Quinzel grew up in an extremely dysfunctional atmosphere. Still, she somehow managed to become a psychiatrist. She first met and fell in love with the Joker when he was her patient at Arkham Asylum. He transformed her into his ideal girlfriend, a bubbly, violent, anarchic psychopath.

Eventually, Harley ends up in Arkham before breaking out. When Harley understands that the Joker is just using her and doesn’t really love her, she becomes obsessed with proving to him and everyone else that she’s a criminal force to be reckoned with.

The title character is voiced by Kaley Cuoco from “The Big Bang Theory” and “8 Simple Rules.” Her outstanding portrayal won her the “Best Voice Actress in an Animated Series” Critic’s Choice Super Awards in 2021.

Poison Ivy:

Poison Ivy

Dr. Pamela Isley was a brilliant botanist who was born with green skin and the ability to control plant growth. She eventually became an ecoterrorist and ended up in Arkham Asylum, where she met Harley, and the pair became best friends.

The character is voiced by Lake Bell from “In a World…” and “How to Make It in America.” 



Basil Karlo is a disgruntled former actor who gained the ability to shapeshift after a pottery incident. He uses his abilities whenever the crew needs a spy.
