The Harley Quinn animated series is a treat not just for Batman fans but DC fans as well, as it saw a number of fan-favorite characters across the DC universe reimagined to fit in with the hilarious Harley Quinn world. What's more, the show created some new original characters that have proved to be just as fun to watch.
With so many characters, some were not used as much as others, even if they did deserve more screen time. Whether these characters were particularly funny or had a lot of potential for further development, it wouldn't have hurt to put these personalities more in the spotlight. But with season 3 on the horizon, some of them could get that chance to shine.
Mr. Freeze
Mr. Freeze is a fan favorite in the Batman Rogues Gallery, partially due to his tragic reasons for turning to crime. Voiced brilliantly by Alfred Molina, Mr. Freeze was not introduced until the first episode of Harley Quinn season 2, in which he traps Harley in a block of ice.
He appears again a few episodes later, but in one of the most bittersweet moments in the entire series, Mr. Freeze sacrifices himself to save his beloved wife, Nora, proving to Harley that there is such thing as an act of true love. With his intentions revealed to be much less malicious than expected and his somewhat sweet and funny personality, it would have been great to have seen more of Mr. Freeze.
Alfred As The Maccaroni
Batman's loyal butler and father figure Alfred does not appear until the Bruce Wayne-focused episode "Batman's Back, Man," which is in the middle of season 2. Whilst Bruce and Alfred's exchanges are among the funniest moments in Harley Quinn, this is not the only reason why Alfred deserved more screen time.
For perhaps the first time in Batman's TV history, Alfred has taken on a costumed vigilante persona of his own called the Maccaroni, fighting crime when Bruce is physically unable to do so. While Alfred's costume is rather amusing, it is brilliant to see him defeat crooks and thugs without breaking a sweat. With his dry wit and dignified persona, watching the butler fight villains in his Maccaroni guise would have been a treat to see more of. Perhaps fans may see the Maccaroni return in season 3.
Queen Of Fables
A lesser-known DC villain, the Queen of Fables is introduced to the show in the third episode "So You Need A Crew?," in which she is trapped in a tax guidebook for trying to destroy Gotham in the 1980s. Initially a role model to Harley, it is soon revealed that the Queen is a ruthless villain who isn't afraid to cross boundaries that even the majority of Gotham's villains deem a step too far.
Despite her sociopathic tendencies, the Queen of Fables was a really fun and funny character to watch, thanks to her forthright personality, and the excellent voice work of Wanda Sykes. What's more, her use of fairy tale characters as arsenal opened up to some both awesome animation and some rather funny (yet sometimes very gruesome) gags. Whilst she ultimately deserved her fate, it was a shame to see her killed off in only the first season.
The Penguin
Oswald Cobblepot, also known as the Penguin, is one of Batman's oldest and most renowned villains. Yet, in the Harley Quinn series, he only appears in two episodes and is brutally killed by Harley at the end of season 2's first episode, the grim finale of one of the best fights in Harley Quinn.
Appearance-wise, Harley Quinn's Penguin isn't dissimilar from most other versions of the character. But personality-wise, he is funny and a delight to watch, partially because of the iconic voice acting of Wayne Knight. What's more, "A High Bar" (perhaps one of the best episodes in the entire series) shows a wholesome side to the criminal kingpin as he takes a night off being a supervillain to happily throw a lavish bar mitzvah for his nephew, Joshua. It would have been a lot of fun to see more of the Penguin, his family, and antics at the Iceberg Lounge.
The Legion Of Doom
In season 1, Harley's main ambition is to get into the Legion of Doom, an organization for the most elite supervillains. Yet aside from Cheetah and eventually Harley, Gotham's branch proves to be an all-male organization. It seemingly meets its end when Joker blows up its headquarters in "Devil's Snare."
The times focused on the Legion of Doom opened up to some of the show's best moments. This includes an ongoing legal battle with an adult store, kicking out Dr. Psycho because his use of the c-word "did not represent their brand of evil", and Bane trying to recruit Harley's crew as his own goons. It would have been exciting to see Harley spend more time in the Legion and make changes within the organization.
Tabitha
The episode "Bachelorette" revealed that fan-favorite King Shark has been betrothed for some time and must return to his underwater kingdom for an arranged marriage he doesn't want any part of. His bride-to-be is Tabitha, a chain-smoking gravelly-voiced hammerhead shark woman who has no interest in marrying him either. Yet to keep the peace between their families, the two agree to marry but can date other people.
Tabitha is an original character in the show and has a lot of potential to be one of the best. From her brief time onscreen, she is quite funny and good at heart. Furthermore, with King Shark as one of the best characters in Harley Quinn, it would be great to see more of their married life and their relationship, whether it remains platonic or not.
Bud And Lou
One of the most iconic elements about Harley Quinn is her beloved pet hyenas, Bud and Lou. Introduced alongside Harley in Batman: The Animated Series, the hyenas were not only loyal minions but Harley's pride and joy, and have been featured across various adaptations. So it would be expected for them to play a key role in Harley's own show.
However, the two hyenas are not introduced until season 2, where they are briefly seen as Harley's new pets on only a few occasions. There was a lot of missed potential with them, and they could have been used for a number of gags, particularly in Harley's misadventures and among her crew. As they are essentially part of Harley's core character, it's a pity not to see her "babies" much in the very show she is starring in.
Catwoman
Like the Penguin, Catwoman is one of Batman's most famous foes. Interestingly, Catwoman isn't introduced until the third episode of season 2, in which it is hinted she has some kind of past with Poison Ivy.
Whilst not the most iconic version of the feline anti-hero, Harley Quinn's Catwoman is certainly one of the funniest and perhaps underrated. She is very confident, self-centered, and aloof, openly turning her nose up at everyone around her. Regina George from Mean Girls comes to mind with this version, and while Catwoman gets some time in the Harley Quinn: The Animated Series: The Eat. Bang! Kill. Tour comic, it would be great to see more of her in season 3.
Joshua Cobblepot
An original character in the series, Joshua Cobblepot is the Penguin's nephew. He is given the chance to shoot Harley at his bar mitzvah after she accidentally wrecks it but Harley uses her psychology skills to undermine his confidence. He later puts a bounty on Harley as revenge using his uncle's Legion of Doom corporate card.
Being the nephew of one of Gotham's biggest crime lords who wanted him to the family business, it would have been cool to see Joshua potentially grow up to be a supervillain, especially as the same person who ruined his bar mitzvah also killed his uncle. What's more, the scene where Bane scolds Joshua for misusing the credit card is one of the funniest yet wholesome moments of the show. Bane could have been a great mentor to young Joshua.
Scarecrow
With his infamous use of fear toxins and his scary appearance, Scarecrow is one of Batman's most terrifying enemies. In fact, he is considered the scariest villain in Batman: Arkham Asylum. Yet in Harley Quinn, he is rather cheerful and oddly amiable to be around — even when he has Poison Ivy captive he is polite. And in the context of the Harley Quinn series, it works surprisingly well.
Scarecrow had some great memorable moments in the show, such as discussing an idea for a potential Pixar's Up sequel with Bane (which actually turns out to be a very good idea), and muttering how Joshua Cobblepot used too many adjectives in his speech. This made him a rather likable character who would have been fun to see more of in the series. Unfortunately, his thoughtful attempt to cheer up Joker by unmasking Batman costs him his life in the season 1 finale.
