"All I've seen the last few months...the last two nights...has challenged everything I ever believed in. It all comes down to one thing. Ethan. He was right. Gotham needs the Batman." ―Detective Ellen Yin

Ellen Yin is a detective for Gotham City Police Department created for the animated series The Batman.


Ellen Yin is a police detective with the Gotham City Police Department, formerly head of her department in Metropolis PD. She transferred to Gotham PD looking for a challenge (it is implied that she left Metropolis due to Superman's presence there). Yin is a career cop at the top of her game, simple and by the book. She is as physically adept at as any male cop she knows, and has proven to be skilled in hand to hand combat. She was initially assigned as a partner to Detective Ethan Bennett.

Yin quickly grows fond of her partner after being tasked with unmasking the Batman. Having shown to be an effective detective, she gains the approval of Chief Angel Rojas. She had a difficult relationship with the Batman initially, and not warming to his alter ego Bruce Wayne so easily either. Ellen doesn't have it out personally for The Batman. As a vigilante, he's breaking the law, and as Bruce Wayne she only sees a spoiled billionaire playboy, despising his seemingly silver-spoon arrogance. She also thinks Catwoman is similar to Batman. She tried to take down Joker, Penguin and Mr. Freeze, but Batman always beat her to the punch.

When her partner and friend Ethan Bennett is transformed into Clayface, due to Jokers putty. Yin loses one of her best friends in the city. Before she and Batman parted ways after fighting Clayface, Batman handed her a Batwave commlink, telling her to call him whenever she needed. Keeping the commlink, Yin later calls Batman her new "partner" during a coffee shop meeting with Ethan's best friend, Bruce Wayne.

Yin soon decides to test her new partnership with Batman, asking for his help in "The Cat, the Bat and the Very Ugly" as she investigates Catwoman and her mysterious new partner in crime. When Yin discovers that the mysterious partner is none other than the Batman himself, she questions her trust in the caped crusader. She decides to trust him though, after he and Catwoman stop one of Penguin's schemes to hold all of Gotham at ransom.

Yin and Batman

Her first true mission with Batman as partners came in "Riddled" when the Riddler planted bombs around Gotham, threatening to detonate them if Yin didn't play his "game". The two worked together to solve the riddles, with Batman communicating secretly with Yin through the Batwave. They are both eventually captured by the Riddler, upon discovering his true plans. Yin and Batman were able to break free and foil the Riddler's plan. Riddler later attempts to reveal Yin's partnership with the Batman to Chief Rojas, but Rojas ignores him, calling him a lunatic.

In the episode "Fire & Ice", Ellen attends a charity party hosted by Bruce Wayne. She tells Wayne that she knows his secret, and he initially thinks that she knows he's Batman. However, the "secret" is that Yin realizes that Bruce's "spoiled, arrogant playboy" persona is only a facade.

When her former friend turned villain, Ethan Bennett resurfaced as Clayface, he is apprehended by Batman and receives therapy at Arkham Asylum. He is later cleared for released after he was deemed safe to return to society, as long as he didn't use his abilities. Yin is relieved to have her friend back, but Bennett is still angry at the Joker and seeks revenge. Yin, along with Batman attempt to reason with him, but he loses control, deciding that it was easier to be Clayface than Ethan Bennett. In the end Yin is the one to take him down with a device given to her by Batman, immobilising him. Later Yin sadly says 'we've really lost him this time'.

Yin and Batman grow closer as partners, with each mission together. Yin starts to trust Batman more than her police colleagues, saving Batman from capture by her newly assigned partner Detective Cash Tankenson in "JTV". Yin is unwilling to accept Tankenson's brash behavior, but when he is targeted by the Joker, she fears that she will lose another partner to the Joker's madness, and orders Tankenson to stay away from him. Her new partner refuses to listen however, and becomes Joker's prisoner. Yin eventually saves him with help from Batman. Tankenson later transfers to a desk job, leaving Yin once again with Batman as her sole partner.

However, their partnership did not go unnoticed by the villains of Gotham, drawing unwanted attention to Yin. In "Strange Minds" in order to get his revenge on both Yin and the Batman, the Joker ambushed Yin in her apartment and knocked her out with a gas. He then kidnapped her and held her hostage at a secret location with bombs rigged to blow after eight hours. Batman attempts to save Yin by entering the Joker's mind to find out her whereabouts. Batman is able to save Yin just in time, after tricking the Joker into revealing where he'd trapped her.

Yin worked alongside Batman until "Night and the City", where her Batwave was destroyed by Rojas, and her badge confiscated. Yin and Batman are then briefly on the run from the GCPD, as well as the Joker, Riddler and Penguin. Her badge was later returned by Commissioner James Gordon at the end of the episode, and she was reinstated. Yin no longer appeared after season 2, though it is implied she becomes Police Commmisioner in the near future during the fourth season episode "Artifacts".

  • Though the character of Ellen Yin is largely original to the series, it appears that she, or at the very least her name, was likely inspired by the character Commissioner Ellen Yindel, from Batman: The Dark Knight Returns. Both displayed strong, anti-Batman beliefs at their introduction, and though never confirmed, it is implied that Yindel, like Yin, developed a certain respect for Batman, after seeing his heroics. It is also mentioned in the Time Skip episode, and likely a nod to the comic, that she became Commissioner.
  • Ellen Yin made her final appearance at the end of the second season and was replaced by Batgirl for the third season onward.
  • Ellen Yin bears a striking resemblance to Elisa Maza from Gargoyles, especially the maroon coat, black shirt, and jeans habitually worn by both.
  • Ellen Yin appeared in a total of 16 episodes in The Batman TV show.
