Harley Quinn season 3 is almost here! Yes, not only do we have a release date confirmed by HBO Max, but a new teaser trailer as well. Let the HarlIvy "Eat, bang, kill" tour begin!

The biggest question, though, revolves around what DC will let this madcap series get away with. Yes, the zany animated show Harley Quinn is earning headlines for one potential scene that DC tried to veto, even though it totally fits. 

Harley Quinn, one of the best shows on HBO Max, has been one of our most anticipated programs of the coming seasons since we binge-watched its first two seasons. It starts as Harley and Mr. J broke up (again), and then follows Ms. Quinn through the trials one must go through to make a name for themselves in Gotham's supervillain ranks. 

All of your favorite Gotham regulars show up, but in very ... deranged versions of their comic book characters. Commissioner Gordon stands out among many, while we still have many questions for Bane. A must-watch for any HBO Max subscriber, here's what we know about Harley Quinn season 3. Oh, and (of course) expect spoilers for Harley Quinn seasons 1 and 2 below.

And there, once you dive into the series, you'll learn that this Harley is different (and a lot more adult) than the version seen in Batman: The Animated Series, where she debuted. For starters, she's got her own group of miscreant wanna-be villains, including the slightly-misogynistic Doctor Psycho. But it's King Shark and Clayface who have proven to be the true scene-stealers of the bunch.

Of course, Harley Quinn season 3 will likely revolve around the big news from the season 2 finale. When we last left Ms. Quinn, she and Poison Ivy were on the run ... from Ivy's own wedding. Yes, the relationship teased throughout all of season 2 has finally come true. We're curious about how Ivy's now-ex-fiancee Kite Man is taking the news.

Harley Quinn season 3 news and updates

  • Harley Quinn season 3 will debut on July 28!
  • We've got the first Harley Quinn season 3 teaser trailer!
  • Harvey Guillén (What We Do in the Shadows) is voicing Nightwing in season 3.

Harley Quinn season 3 teaser trailer

Accompanying the above trailer, HBO Max provided an official Harley Quinn season 3 description. It reads:

The mayhem and madness continue in season three of this biting and uproarious adult animated comedy series. Wrapping up their “Eat. Bang! Kill. Tour,” Harley Quinn (Kaley Cuoco) and Poison Ivy (Lake Bell) return to Gotham as the new power couple of DC villainy. Along with their ragtag crew – King Shark (Ron Funches), Clayface (Alan Tudyk), Frank the Plant (JB Smoove) - "Harlivy" strives to become the best version of themselves while also working towards Ivy’s long desired plan of transforming Gotham into an Eden paradise.

Harley Quinn season 3 release date confirmed

HBO Max announced that Harley Quinn season 3 debuts on Thursday, July 28, via a press release (opens in new tab). Three episodes will debut on July 28, with one per Thursday after that.

Even the people behind Harley Quinn season 3 don't have a firm answer. Showrunner Justin Halpern told the Masters of None (opens in new tab) podcast that "I think it'll probably come out either the very end of this year or the beginning of next, just because animation takes so long." So, that's either late 2021 or early 2022.

He also noted we'll get a standalone Joker episode in season 3, and that we'll spend another episode in a character's brain.

Oh, and expect Harley Quinn on HBO Max, and only HBO Max (which is on all the best streaming devices). As reported by Deadline, the show will not be on the DC Universe service where it debuted. That service is moving away from original programming. 

Harley Quinn season 3 cast

The rogue's gallery of villains and heroes in Harley Quinn has been as dense as in any show, and often times that's the point. Alan Tudyk doesn't just voice Clayface and Joker, he's also been Calendar Man, Doctor Trap and Condiment King.

We've got the expected gallery of folks expected back for Harley Quinn season 3 below, but there's also some news of new names behind the microphones. Patrick Schumacker (writer/producer for the show) announced on his Twitter (opens in new tab) that Sam Richardson (Veep) is joining the show. He omitted the character Richardson will be voicing.

As for who else could be heard? Halpern is looking to get a trio of villains voiced by the likes of Nathan Fielder, John Wilson and Joe Pera. Basically, "villains who have really meek, old men voices." Right after he said that, he confirmed that The Mad Hatter will be in Harley Quinn season 3.

As for Kite Man, Halpern and Schumacker told EW (opens in new tab) that the character will not be a threat to Ivy and Quinn's romance. That interview also revealed that Gotham is stuck with Bane, as that character will never be killed off.  Halpern specified that "We'll kill almost any character that's not Harley or Ivy, but we'll never kill Bane."

Harley Quinn season 3: Nightwing confirmed

Harvey Guillén, who plays Guillermo in What We Do in the Shadows, has been cast as the voice of Nightwing, according to Deadline (opens in new tab).

Nightwing is a character that originated in the Superman comics but is better known as Batman's sidekick Robin. In the Batman comics, he was introduced as orphan Dick Grayson. He takes the name Nightwing after he and Batman go their separate ways.

Harley Quinn season 3 controversy

As reported by Variety (opens in new tab), the folks at DC Comics tried to stop a certain risque act from showing up in Harley Quinn season 3. Halpern says "we had a moment where Batman was going down on Catwoman. And DC was like, 'You can’t do that. You absolutely cannot do that.' They’re like, 'Heroes don’t do that.'"

DC's team tried to rationalize by saying "we sell consumer toys for heroes. It’s hard to sell a toy if Batman is also going down on someone." It's unclear if the scene made it.

Harley Quinn season 3 sneak peek

This is not a trailer. But it's what we got for Harley Quinn at DC Fandome 2021. It's a rough set of storyboards and a nice visual asset of Ivy and Harley. Check it out for yourself, and get a chuckle at Gordon's continued chaos.
