You’ve probably seen a dozen versions of Harleen Quinzel by now. Most people think they know her: the high-pitched voice, the toxic obsession with Joker, and the chaotic "anti-hero" energy from the Suicide Squad movies. But Gotham Knights Harley Quinn is a completely different beast. Honestly, it’s a bit jarring at first.
She isn't a sidekick here. She isn't pining for "Puddin."
In this game, Harley is older, wiser, and significantly more dangerous because she’s finally operating with a full deck—or at least, her own twisted version of one. If you’re jumping into the game expecting the bubbly gymnast from the Arkham series, you’re in for a massive wake-up call.

The Harley Quinn Nobody Talks About
The developers at WB Games Montréal did something pretty bold. They skipped the "finding herself" phase. When we meet her in Gotham Knights, she’s already a veteran of the criminal underworld. She has a history with Batman that’s finished. With Bruce Wayne out of the picture, she isn’t grieving; she’s capitalizing.
She’s basically running a high-stakes psychological experiment on the entire city.
Instead of just hitting people with a hammer (though she still does that), she uses her background as a psychiatrist to manipulate Gotham’s citizens. She’s selling a fake "self-improvement" lifestyle, using neural implants to "free" people from their inhibitions. It’s essentially a cult-leader vibe, and it makes her feel way more grounded and scary than the usual "clown girl" trope.
Why the Voice Sounds Different
Kari Wahlgren takes over the role from the legendary Tara Strong, and it’s a deliberate shift. The voice is lower. It’s raspier. It sounds like a woman who has spent decades screaming in Arkham and finally found a tone that commands respect. Some fans find it weird, but if you listen to how she talks to Nightwing or Batgirl, there’s this condescending "auntie" energy that’s just... chef’s kiss... perfect for a mentor-turned-monster.

How to Actually Beat Her (Because She’s Tough)
The boss fight with Gotham Knights Harley Quinn at the hospital is a notorious difficulty spike. If you aren't prepared, she will absolutely wreck you with that electrified sledgehammer.
Here is the real talk on how to handle her:
- Ignore the "Freaks" (Mostly): She floods the arena with her devotees. They are there to distract you. Use your momentum abilities to clear the small ones quickly, but don’t let them bait you into a corner.
- The Bomb Phase is the Killer: This is where most players fail. Harley sets off bombs around the room. You have to disarm them while she’s actively trying to cave your skull in. Priority one: The Bombs. If the timer hits zero, it’s game over.
- Perfect Evades are Mandatory: You cannot tank her hits. Her hammer has massive reach and deals elemental shock damage. You need to time your dodges to trigger "Perfect Evade" attacks. This is the only way to reliably chip away at her health without getting flattened.
- Character Choice Matters: Red Hood’s ranged attacks make this fight significantly easier because you can stay out of her hammer’s radius. If you're playing as Batgirl, use her drone to keep the mobs busy while you focus on the bombs.
The "Third Act" Villain
What most people get wrong about this version of Harley is thinking she's just another "Case File" to check off. The game frames her as a mirror to the Knights themselves.
Think about it.
The Knights—Dick, Barbara, Jason, and Tim—are all trying to figure out who they are without Batman. Harley has already done that work. She’s the "graduated" version of a sidekick. She tells the heroes that they need a villain like her to define them. It’s a meta-commentary on the Batman mythos that actually carries some weight.
She isn't just "crazy" anymore. She’s intentional.
Limitations of this Version
Is she perfect? Nah. Some players feel the "implant" plotline is a bit of a stretch for her character. And honestly, her boss fight can feel a bit repetitive if you’re playing solo. But in terms of character design, seeing her in a more "mature" supervillain costume—heavy leather, structured diamonds, and a tactical hammer—is a refreshing break from the skimpy outfits of the early 2010s.

Next Steps for Your Playthrough
If you're struggling with the Harley Quinn arc, make sure you've hit at least level 18 before tackling the "Chaos in General" mission. It’s worth unlocking your Knighthood Tree first so you have your specialized traversal (like the Glider or Teleport) and your Ultimate ability. Once you beat her, check the Belfry for the unique gear blueprints she drops—the "Freaks" inspired gear usually has some of the best elemental resistances for the mid-game.
Don't let the hammer hit you twice. One hit stuns; the second one sends you back to the checkpoint. Good luck.
