Warning: This list contains spoilers for Harley Quinn season 3.Season 3 of Harley Quinn is now airing on HBO Max, giving fans all the Harley Quinn/Poison Ivy romance they could want. This season, everything revolves around Ivy and her
goals to terraform the world, while Harley does her best to be a supportive girlfriend. They are accompanied by their crew, but as the altered end credits of episode 1 show, this is absolutely a series about Harley Quinn & Poison Ivy.
Despite being extremely focused on the two leads, season 3 has introduced many new characters to bulk up the landscape of Gotham, particularly since the Bat-family is becoming more significant as the show continues. While many of the characters seem to have been included as little more than fan service, a few have really been able to push the story forward, keeping the show on track despite its tendency to meander through tangents.
Jervis Tetch is a major player in Batman media, creating mind-control devices and slipping into rhymes and Alice in Wonderland references. However, while Batwoman‘s Alice came across as interesting and complicated, Mad Hatter tends to come across as creepy, which is what Harley Quinn highlighted.
In several stories, including Arkham Asylum: A Serious House on Serious Earth, Streets of Gotham #4, and Batman: Haunted Knight, Tetch displays an uncomfortable desire for children that makes the funny character into a real-world monster. With that comics’ history, fans are pretty happy when Harley decides to take care of him for good.
While the Suicide Squad has been referenced in Harley Quinn since Season 1, Amanda Waller’s first appearance came this season, when she was kidnapped by Harley after insulting Ivy. The character is famously abrasive, so it’s no wonder that she rubbed Harley the wrong way.
While Ivy seemed to respect Waller’s power, Harley just saw someone who had insulted her girlfriend. Though Waller was able to get away, the fact that the Suicide Squad didn’t really care that she was missing suggests that she will have far less power in this version than in Waller’s prior appearances. However, it seems likely that she will become a more significant figure later on, given how deeply Harley is tied to the Suicide Squad in other media.
Queen Elizabeth II actually has quite the history in pop culture, from her personal appearance as a Bond girl in the opening of the London Olympics to her likeness’s presence in Minions. In one of the last examples of this before her death, Queen Elizabeth II was portrayed as a comedic hostage of Harley Quinn.
The Queen was remarkably calm about the entire situation, answering Ivy’s questions about her gardening habits until the British air force came to take her back. It was a fun nod to the real world and presented the Queen with more dignity than most characters on the satirical show.
When Harley Quinn first started, it was obvious that the show was keenly anti-Joker, making him the biggest obstacle for Harley to get past. However, since he took a few trips through tanks of chemicals and got together with Bethany, he’s actually turned out to be a pretty good guy.
With that being said, it was fun to see the Joker pitted against Debbie, the stereotypical rich mom. The show transformed Joker back into a funny villain, rather than a grounded, realistic one, and that made it possible for him to go up against Debbie with dramatic flair. While Debbie is unlikely to get any fans of her own, she was a useful character to continue the Joker’s development.
Music Meister has been a fan-favorite character since his appearance in Batman: The Brave and the Bold, but his backstory is extremely malleable. In the CW’s DC shows, Music Meister is focused on fixing emotional damage more than global domination—and that seems to be the route the character takes in Harley Quinn.
Music Meister is Bruce Wayne and Selina Kyle’s couples therapist, which makes a lot of sense given his earlier appearances. He’s more of a plot convenience than a character, but that doesn’t make him any less enjoyable. His intervention helped Bruce and Selina learn why their dynamic wasn’t working, and it may be critical to helping Harley and Ivy find equal footing in their relationship moving forward.
Between his own show, his time on DC’s Legends of Tomorrow, and now an appearance on Harley Quinn, John Constantine is one of the biggest names in DC Comics media right now. He appears in the fifth episode of season three, offering to help Ivy find Swamp Thing if she and Harley will have a wild drinking competition with him first.
It’s only right that Constantine’s first appearance in Harley Quinn is in the Swamp Thing episode, because his first appearance in the comics was in Swamp Thing #37. He doesn’t get too much focus as a character in his own right, but fans do get to see him be as self-destructive as ever. As an added bonus, Harley Quinn‘s John Constantine is voiced by Matt Ryan, suggesting that it may actually take place in the CW’s Arrowverse.
Season 3 has had a better focus on Ivy than previous seasons, so it only makes sense that fans would get to see another major environmental character from the comics canon—Swamp Thing. His backstory changes with each version, but it’s great to see the character keep attention after his solo show was canceled.
In the show, Swamp Thing is vastly over-emotional, which leads him to go on a rampage when he gets rejected by Nora Fries. However, his relationship with Ivy is the heart of the episode, which ends up being important in later installments. He represents a more emotional version of Ivy, and having him there helps her learn to open up and be okay with imperfections.
Harley Quinn has provided multiple different versions of Bruce Wayne, including several animals that watch their Martha and Thomas Wayne look-alike parents die in front of them. But while Batman himself is constantly the source of mockery, season 3, introduced Bruce as a child, which specifically represents his mental state.
The series has done a lot with Harley’s psychological background, and Kid Bruce gives her the best opportunity to use it, as she enters his mind and rescues him from the recurrent memory of his parents’ deaths. The childhood version of the character is far more sympathetic and interesting than the standard presentation of Batman, and he feels authentic in a way few of the show’s characters ever achieve.
Ultimately, Golden Glider isn’t a major player in the comics, despite her brief time on The Flash, but she manages to make quite the impression with her appearance on Harley Quinn. She is pretty, kind, and compassionate, which makes her a perfect match for Kite Man. Fans who thought he deserved better than how Ivy treated him should be pleased to know he has such a supportive partner now.
Golden Glider is expected to be a key character in Kite Man’s spin-off Noonan’s and her time on Harley Quinn helped pave the way for that. Assuming she follows the broad strokes of her comic character, it should be interesting to see how her brother (Captain Cold) figures into her relationship and villainous path.
A classic member of the Bat-family, fans were excited to learn that Nightwing was coming back to Gotham. While the character has had flirtations with Harley in other media, however, he is played for laughs in Harley Quinn. He enters Gotham with a dramatic monologue, and his character is repeatedly lampooned from then on.
While Nightwing technically debuted in the spin-off comic Harley Quinn: The Animated Series – The Eat. Bang! Kill. Tour, his first animated appearance on the show focuses on his desire to be viewed as a serious, established hero in his own right. Though he can seem like a brat, the show is better for his presence, as he adds a layer of history to the Bat-family that Batgirl and Damian don’t have.
