Harley Quinn was once an intern psychologist at Arkham Asylum, who became obsessed with one of her patients. This unnamed individual, whom we know as The Joker, became her mentor and partner in crime. Together, they wreak havoc on the streets of Gotham City.

Seductive, violent, and creepy, Harley Quinn is a central figure in Batman video games. She most often is the villain, but she has also played the hero. Did you know that Harley Quinn once joined the Justice League, DC Comic's team of fictional superheroes? "A-Okay, Mr. J." This is ranking the ten best video games with Harley Quinn.

10 Lego Batman 2: DC Superheroes

Harley Quinn appears as one of the bosses in the game, which makes her appearance even more special. LEGO Batman 2: DC Super Heroes lets you choose between fifty playable characters—and ten more with DLC. Each character is polished, as they each have a moveset unique to their style.

The game's open-world is a joy to explore. It's the first time that developer Traveller's Tales attempted an open-world game with spoken dialogue; the result is groundbreaking.

9 The Adventures of Batman & Robin

Back when Konami was in the biz of developing and publishing Batman games, The Adventures of Batman & Robin stood out.

The game released for platforms such as the Super Nintendo Entertainment System (SNES), Sega Genesis, Game Gear, and Sega CD. There are substantial version differences, but each features a variety of Batman bosses, including the fantastic Harley Quinn.

8 Batman: Vengeance

The plot of Batman: Vengeance surrounds the mysterious death of Batman's archnemesis, the Joker. Naturally, Harley Quinn appears in the game as a central figure. Batman: Vengeance begins with a disguised Harley Quinn, so you won't have to go far into the game to encounter her.

The game is based on The New Batman Adventures animated series, which is a continuation of Batman: The Animated Series.

7 Injustice: Gods Among Us

Harley Quinn appears in Injustice: Gods Among Us as a character with a variety of weapons and gadgets at her disposal. These weapons and gadgets are dangerous in her hands. They include booby-trapped items, a revolver, and a giant hammer. How she manages to have all these items on her person is perplexing.

Despite the game's exaggerated realism, it is one of the best fighting games of our generation. The story is set parallel to the DC multiverse.

6 Batman: Arkham Knight

Batman: Arkham Knight is not the most exceptional Batman game, but it might be the best Harley Quinn game. This game contains the Harley Quinn Story Pack add-on, which lets you play as Harley Quinn for the first time in the Arkham series.

Gripping a baseball bat, Harley Quinn attempts to rescue her villainous friend Poison Ivy. The opportunity to play as the bad guy (or in this case girl) makes this DLC stand out. It's a short DLC, but Harley Quinn appears in the main story as a villain too.

5 Batman: The Enemy Within

Although the original Batman: The Telltale Series received mostly mixed reviews, it is widely agreed that Batman: The Enemy Within tells an extraordinary story. It has a wider variety of Batman villains than the first, and the gameplay is more immersive.

While the Batman: The Telltale Series is more of an origin story, Batman: The Enemy Within includes villains like Harley Quinn, who were added later in the comics. If you skip the first or decide to play it later, Batman: Enemy Within is a must-play.

4 Batman: Arkham Origins

Batman: Arkham Origins had a rocky launch and was unplayable for a bunch of players when it released. They fixed most of the bugs, so what remains is an intriguing origin story. It also features multiplayer, which is a first for the series.

Batman: Arkham Origins takes place before the other Arkham games. Batman encounters Harleen Quinzel before she became Harley Quinn. At Blackgate Prison, she is in-training under the psychiatrist Dr. Hugo Strange.

3 Injustice 2

Injustice 2 is related to the comic book of the same name. The game features the widest variety of villains for the series. A great deal of polish was put into each character. The gameplay mechanics are refined to create seamless fights between favorite DC characters.

Harley Quinn is a playable character in Injustice 2. Shockingly, she is an in-training member of the Justice League. Led by Batman and others, Harley Quinn uses her gadgets and weaponry to fight for the good guys.

2 Batman: Arkham Asylum

The game that started it all had a more narrow focus than other Batman: Arkham games, but laid the foundation for the rest of the series. Depending on the player, a story-based linear game could be more appealing. The detective work aspect of the game is refined like no other Batman game. With Harley Quinn as one of the villains, we highly recommend playing Arkham Asylum.

Batman: Return to Arkham is 2018's remaster of Arkham Asylum and Arkham City. Although it's not the remaster we hoped for, it is the best way to play these games.

1 Batman: Arkham City

If you're looking for the top video game with Harley Quinn, then look no further. Batman: Arkham City took the linear-based Batman: Arkham Asylum and added an immersive open-world. Its usage of stealth mechanics is masterful.

Harley Quinn appears in a story-based DLC titled "Harley Quinn's Revenge," as well as the main story. The DLC takes place after the events of Batman: Arkham City and lets you play as Batman's sidekick, Robin.
