8 Batman: Harley and Ivy

By Paul Dini, Bruce Timm, and More

Harley Quinn is no stranger to animation. In fact, her debut is in Batman: The Animated Series, and she eventually transitions into the comics. For those who want to go all the way back to the first animated iteration of Harley Quinn, they can rewatch the iconic cartoon, or they can pick up Batman: Harley and Ivy, a comic from the creators of Harley Quinn, Paul Dini and Bruce Timm.

Batman: Harley and Ivy is all about the friendship between the titular women...

Batman: Harley Quinn & Poison Ivy is all about the friendship between the titular women, with Harley doing everything in her power to help Ivy out with her big plan to save the environment, causing a little mayhem and chaos along the way. Harley and Ivy are opposites of each other personality wise in this comic, but that does not undermine their friendship, even when they get under each other's skin.

7 Harleen

By Stjepan Šejić and Gabriela Downie

While Harley Quinn is often a humorous character, there is a dark and tragic side to her, especially when it comes to her origin story. Max's Harley Quinn does take a look at her origin, as well as the complicated feelings Harley has toward it because of her past with the Joker. For a more in depth and serious look at her transition from Dr. Harleen Quinzel to Harley Quinn, look no further than the DC Black Label series Harleen, a visually stunning comic that is a beautiful nightmare at times.

Harleen retells Harley Quinn's origin as a doctor in Gotham and the early days of her relationship with the Joker from her perspective. This miniseries is a great look into the psyche of Harley Quinn, and it is also a nuanced depiction of her origin and the toxic, abusive relationship she had with the Joker. There is even a parallel to her and Batman, as both do not want to give up on the criminals of Gotham, but the paths they end up taking are drastically different.

6 Harley Quinn: No Good Deed

By Stephanie Phillips, Riley Rossmo, Laura Braga, and More

After watching the recent season of Harley Quinn, fans may want to dive directly into her current comic run, which is nearly fifty issues long as of the time of writing. While there is a jumping in point with Harley Quinn #44 as part of the DC All In soft relaunch, some may want to go back to the very beginning, which features a different creative team than the one currently tackling her more recent issues.

In addition to her own #1 from 2021, Harley Quinn was also heavily featured in the Batman run from that year, especially in the Fear State event.

The first six issues of this run are collected in Harley Quinn: No Good Deed. Like in the Max series, Harley Quinn is no longer a straight-up villain. Instead, she is back in Gotham City, and she is ready to atone for her past transgressions and crimes, but she's going to do so in her own, unique way. Phillips and Rossmo are a dream team for Harley Quinn, with the former capturing Harley's distinct voice and the latter complementing it with a zany art style.

5 Harley Quinn: Hot in the City

By Amanda Conner, Jimmy Palmiotti, Chad Hardin, and More

Harley Quinn's animated series pulls inspiration from her long comic and cartoon history; however, it is also telling its own story. That being said, there are still some specific comics that it is pulling heavy inspiration from, including the New 52 Harley Quinn run, which has issues #0 through #8 collected in Harley Quinn: Hot in the City.

This iconic run has influenced a lot of contemporary iterations of Harley Quinn, including Margot Robbie's portrayal of the character and the Max series' iteration of the character. In this run, Harley Quinn starts a new life for herself on Coney Island, leading to plenty of chaotic antics with new characters and familiar faces, like Poison Ivy. This comic is another essential Harley Quinn read, as it is unapologetically Harley.

4 Harley's Little Black Book

By Amanda Conner, Jimmy Palmiotti, and Six Superstar Artists

Fans of Harley Quinn's New 52 run will also want to pick Harley's Little Black Book, which sees Harley team up with some heavy hitters from DC Comics, like Wonder Woman, Green Lantern, Zatanna, Superman, Lobo, and the DC Bombshells. The power writing team of Amanda Conner and Jimmy Palmiotti continues the character's story, capturing her comedic voice yet again.

The Max animated series sees Harley Quinn interact with DC characters from all across the DC Universe, like Superman, Wonder Woman, Lex Luthor, and more, so this series is perfect for fans who want to see Harley Quinn cross over with other DC characters outside the world of Gotham City - all depicted by some superstar artists to boot, like Neal Adams and Simon Bisley.

3 Birds of Prey

By Kelly Thompson, Leonardo Romero, Jordie Bellaire, and More

For another Harley Quinn team up, fans of the Max series do not need to look any further than the first arc of the 2023 Birds of Prey series, now collected as a trade paperback. In Season 4 of Harley Quinn's animated series, she tries to work alongside the Bat-Family, eventually realizing that team may not be exactly what she's suited for. In the comics, though, she does find a heroic team she folds into much better, despite some hesitation from her teammates.

Said team is the Birds of Prey, led by none other than Black Canary. Also on board are Big Barda, Batgirl Cassandra Cain, Zealot, and Harley Quinn herself. Black Canary has assembled this team to save her younger sister, with each member - even Harley - bringing something essential to the mission. The series' first arc set the bar high for Birds of Prey, which continues to be a fan-favorite series in DC's current line.

2 Poison Ivy

By G. Willow Wilson, Marcio Takara, and Many More

While Harley Quinn is the titular character of the Max series, her co-lead is none other than her girlfriend, Poison Ivy. Their relationship is one of the strongest points of the show, and Poison Ivy stands out even beyond her relationship with Harley Quinn. For anyone who adores Ivy in the cartoon, they will love her in her ongoing series, which began in 2022 as a miniseries, only to be so successful that it was granted ongoing status, raking in accolades and awards.

Wilson and Takara have been on this series since the very beginning, and they have been winning readers over with every single issue, including those with guest artists. At the start of the series, Ivy sets out on a road trip to save the world by taking out humanity with a deadly fungal infection. That's just the beginning of one of DC's best comics of the 2020s, and it's perfect for anyone wanting more Ivy post Harley Quinn's animated series.

1 Poison Ivy: Thorns

By Kody Keplinger and Sara Kipin

Another Poison Ivy comic fans of Harley Quinn's animated series can turn to is going to be a young adult graphic novel. In the animated series, Harley gets a glimpse into Ivy's relationship with her father, which is also addressed in Harley Quinn: The Animated Series - The Eat, Bang, Kill Tour. To get another take on this familial relationship, look no further than Poison Ivy: Thorns.

Poison Ivy: Thorns is a unique Gothic romance about social outcast Pamela Isley and goth girl Alice Oh. However, Pamela's father has plenty of secrets, which threaten this budding relationship as well as the girls' well-beings. While not part of the main continuity, this graphic novel still captures Ivy's trust issues and rage, as well as a softer part of herself reserved for a few humans, like Alice and Harley Quinn.
