Who is Behind Harley Quinn Season 4?
Harley Quinnwas originally created, written, and executive-produced by the trio ofJustin Halpern,Patrick Schumacker, and Dean Lorey. They all ultimately worked together as showrunners on the series for the first two seasons. With Season 3, however, Lorey could not return to the series. This led to new co-showrunnersChrissy PietroshandJessica Goldsteinstepping in to fill his role alongside Halpen and Schumacker.
Leading up to Season 4’s production, there were more behind-the-scenes changes. Halpern and Schumacker stepped down as co-showrunners to dedicate their focus towardsaHarley Quinnspin-off series, titled ‘Kite-Man: Hell Yeah!’ (formerly announced as Noonan’s). This series will focus on the titular Kite-Man and his new girlfriend, Golden Glider, first introduced in Season 3, as they run a popular bar for Gotham’s criminal population together. The spin-off series does not have a release date yet.
In their absence,Sarah Peters, who has previously worked as a writer and producer on the series, was promoted to the showrunner role for Season 4. She will be accompanied by series directors such asCecilia Aranovich,Juan Joe Meza-Leon,Vinton Heuck, and an extensive team of writers.

What Happened Previously on Harley Quinn?
At the beginning of Season 3, Harley and Ivy have fully embraced their official new status as a couple, taking time away from Gotham to embark on their ‘Eat, Bang, Kill Tour.’ Upon their return to Gotham, though, cracks in their relationship began to show once they made plans to terraform the planet and allow plant life to thrive supreme again.
Meanwhile, Batman kidnaps Frank the Plant for his secret experiments. He wants to try resurrecting his parents, having never gotten over their tragic loss. This leads to Harley learning that he is Batman, a secret she struggles to keep as the experiment accident unleashes a zombie apocalypse. Harley collaborates with the Bat-Family (Batgirl, Nightwing, and Robin) to undo Bruce’s actions. Ivy hopes to use the zombies to fulfill her own terraforming plans after significant setbacks.
Season 3 ultimately ended with Ivy forgiving Harley for ruining her plans and helping save the city.Harley is nowpraised as a hero and realizes she enjoys being good. She then joins the Bat-Family at Bruce’s request as he goes to jail for his actions. Harley keeps this hidden from Ivy, who Lex Luthor approaches with an opportunity to lead the Legion of Doom’s branch in Gotham.
Additionally, we saw a few significant side stories. The first was Commissioner Gordon’s campaign for mayor. Two-Face was manipulating Jim to become the district attorney again. However, after discovering this, Jim withdraws from the election, allowing a now family-oriented Joker to win the position. More absurdly, Clayface also disguised himself as Billy Bob Thornton! Why? It was to secure a role as Thomas Wayne in abiopic film directed by a fictional James Gunn. Last, but not least, King Shark also saved his home (the Shark Kingdom) from being sold to their enemies, but this came with the tragic cost of his brother, Prince Shark’s life.
A bonus Valentine’s Day special was also released earlier this year. Set after the Season 3 finale, this special explored the many romantic relationships (or attempts to form one) of different heroes and villains across Gotham City. While it didn’t have any major set-ups for Season 4, it placed a great spotlight onHarley and Ivy’s evolving relationshipas they continue to grow closer as a couple.
What Will Harley Quinn Season 4 Be About?
Regarding a series likeHarley Quinn, all bets are off on trying to predict where a storyline could be heading at any moment. Just as one example, who could have imagined the Joker becoming a caring father figure who becomes the mayor of Gotham? It’s crazy, to say the least, but fortunately, we know a few seemingly ‘normal’ storylines will be important in Season 4.
The first of which will be further exploring Harley’s time with the Bat-Family. Being a hero is no easy task! Though she has potential, it will likely be a learning curve for Harley as she adjusts to hero life and working within this new team. It will also be interesting to see how long she can hide her hero side from Ivy and the rest of the gang.
Speaking of Ivy, we don’t know if she will accept Lex’s offer. By running the Legion of Doom’s Gotham branch, she would gain significant power and resources compared to other villains in the city. Following the failure of the terraforming plan, this offer may prove to be all the incentive she needs to create a new ingenious plan.
Also, while King Shark and Clayface’s storylines are impossible to guess, other characters like Bruce, Jim, and Joker will likely continue to have supporting roles in Season 4. Whether it’s through Bruce’s redemption in jail or seeing Jim operate the GCPD under Joker’s watch, it will be surprising to see if and how they will tie into the bigger storylines moving forward.
