'Batman: The Brave and the Bold' (2008 - 2011)
En la animación del Hombre Murciélago Batman: The Brave and the Bold, Harley Quinn no tiene gran importancia. De hecho, solo aparece en un episodio, pero merece la pena destacarlo por la originalidad de su intervención y el aspecto tan distinto que presenta en comparación con el resto de su trayectoria.
Harley llega en el episodio 45 de la serie con un diseño en blanco y negro muy al estilo de la década de los años 20. Resulta un poco raro ver cómo le queda a la villana, pero hay una razón detrás: El Joker le ha robado la voz y le ha obligado a que tenga que comunicarse mediante tarjetas de diálogo que parecen sacadas de una película muda.

The chemical vat controversy

The origin of the Joker and Harley Quinn's toxic relationship was altered for the New 52, DC's 2011 revamp of its entire line. The changes were subtle on the surface, but for many Harley Quinn fans, the New 52 version of the character was totally different at the core. In Paul Dini and Bruce Timm's seminal one-shot The Batman Adventures: Mad Love, Harleen Quinzel falls in love with the Joker during their therapy sessions and, even though she was heavily influenced by the Joker, she joins his ranks willingly. That's not the case in the New 52.
In the updated origin story, the Joker pushes Quinzel into a vat full of the same chemical that bleached his skin white and turned him insane, and he does so against her will. For many, this fundamentally changed who Harley Quinn was as a character, altering her agency and the whole nature of her relationship with the Joker. "This made Harley appear as more of an unwilling victim than she had ever appeared before," one Outer Places piece on Quinn's origins claims. "In the New 52, she became a sociopathic, psychotic monster not totally by choice, but at least partially because of the Joker's cruelty."
David Ayer's Suicide Squad featured a mix of both origins, with Margot Robbie's Quinzel taking an oath to the Joker and jumping into the vat herself. The actress has gone on the record multiple times since then, saying she majorly regrets doing the scene because of how disgusting all that slime was.
The Truth About Harley Quinn And Joker's Relationship

For the longest time, Superman and Lois Lane stood head and shoulders above the rest as DC's most famous couple, but that's arguably no longer the case. Clark Kent has been romancing his Daily Planet colleague for more than 80 years now, but over the past few decades, a new power paring has emerged.
When news broke that Margot Robbie was going to be portraying a live-action version of Harley Quinn in 2016's Suicide Squad, professionals expressed concern. Dr. Wind Goodfriend, principal researcher for the Institute for the Prevention of Relationship Violence at Buena Vista University, told MTV that current and former victims could be "re-traumatized" by the Joker's abusive behavior . but Quinn has actually had it much, much worse in the comics. The Joker is often violent towards poor Harley, but she's become so much more than his victim over the years. Let's take a look at their colorful and extremely complicated relationship.
The Joker has tried to kill Harley Quinn on several occasions


David Ayer's Suicide Squad was a highly divisive movie, pulling in just shy of $750 million at the worldwide box office despite the fact that the vast majority of critics trashed it. If there was one thing that everyone could agree on, it was that Margot Robbie stole the show as Harley Quinn. Fears that the character was going to become a punching bag for Jared Leto's Joker turned out to be unfounded — although it took a last minute change of heart from the studio. It seems as though Warner Bros. got wise to a possible backlash and decided to make the Joker's relationship with his girlfriend a little less abusive.
According to Jared Leto, Warner Bros. cut enough Joker scenes out of Suicide Squad for a separate Joker movie. The extent of the cuts was revealed when a list of deleted scenes found its way onto the internet (via SlashFilm), and the reason for their axing also became abundantly clear — they were way too violent. In one unused shot, the Joker backhands Quinn across the face (footage of this slap being filmed was leaked online well before Suicide Squad hit cineplexes), and the crazy couple's big helicopter rescue scene was reportedly re-shot. In the final cut, Quinn falls from the chopper after it gets hit, but reports suggest that the Joker tossed Quinn out of the moving helicopter during a heated argument in the original cut.
