    Joker References "The Killing Joke" Arc

    In Harley Quinn, Joker says he paralyzed Police Commissioner Gordon's partner and is now seeking revenge. This isn't exactly what happens in the comic Batman: The Killing Joke, but it's extremely close. In the comic, Joker paralyzes Gordon's daughter, Barbara Gordon. Either way, Joker paralyzing someone close to Gordon is most certainly canon.

    Joker Killing Jason Todd Is Canon

    In a flashback sequence, the audience gets to see the first meeting between Dr. Harleen Quinzel and Joker. Batman brings him in and interrogates him about a rogue bomb the only way he knows how, with his fists, of course. Joker answers, "Why don't you ask Robin? Oh, wait. Jason Todd is dead, that's right, because I killed him."

    This quick line makes this tragic comic arc canon in Harley Quinn.

    Harley's Past As A Gymnast

    It's no secret Harley used to be a gymnast, before she even became a doctor. Her flexibility and gymnastics skills faired well in the comics, as she's light on her feet and able to (literally) do backflips over her enemies. In a flashback in Harley Quinn, the audience sees this side of Harley, as she was apparently good enough to compete in the Olympics.

    Adam West's Shark Repellent Comes Back

    In Batman: The Movie (1966), Adam West as Batman heroically goes head-to-head with a shark, and comes out victorious by using a spray can of "Shark Repellent." This handy invention makes another round in Season 1 of Harley Quinn, when Batman uses it on a ferocious King Shark.

    The Suicide Squad Keeps Trying To Recruit Harley

    Early in Season 1, Harley's crew gets a package full of Suicide Squad merchandise. King Shark asks if it's their new name, but Harley responds, "Ugh, it's a group that keeps trying to get me to join." They do wear the shirts the entire episode, though.

    Bane's Petty Reason For Blowing Up Gotham Stadium

    One of the best parts about Harley Quinn is Bane. The design is straight out of The Dark Knight Rises, and the only thing on his mind is blowing stuff up. The smoothie guy who gets his name wrong? Blow him up. Insulted at a party? Blow it up. And apparently, he only blew up that stadium in The Dark Knight Rises because it was an answer to a trivia question he got wrong.
