The Joker shows his face in Gotham teaser video

Gotham star Cameron MonaghanGotham fans can now get a sneak peek at guest star Cameron Monaghan as The Joker—just in time for April Fool’s Day. The Fox show will air its two-part series finale on April 18 (titled They Did What?) and April 25 (titled The Beginning…). The Joker will appear in the final episode of the show, as it ends its fifth season with a bang.

The terrifying, scarred, and balding Joker, who is shown in both a prison jumpsuit and the character’s a signature purple suit, appears in a new teaser video against a backdrop of disarmingly jaunty music.

Monaghan previously stole the series when he played twin characters Jerome and Jeremiah Valeska. The twins, children of a nymphomaniac circus performer, served as an homage to the Joker character—comic book’s most terrifying comedian. Monaghan, who is known for his role on Shameless, won accolades for his performance as the ominous twin brothers.

The Joker is comic books’ scariest comedian

This is the first time that Batman’s ultimate nemesis will appear in the critically-acclaimed series. Instead, the series has spent its earlier episodes focusing on origin stories for other well-known villains such as the Penguin, Riddler, and Catwoman.

In another twist on the villain, Joaquin Phoenix is starring in the upcoming film simply titled Joker. That film will feature Phoenix as a failed stand-up comic who resorts to a life of crime. That film is reportedly inspired by Martin Scorsese’s dark cult-classic The King of Comedy starring Robert De Niro.

More recently, Academy Award-winner Jared Leto portrayed the villain in the DC blockbuster—but almost universally hated—Suicide Squad. The Joker character was heavily edited down, according to Leto, and there were talks of a potential standalone Joker movie starring Leto.

Watch Gotham on Fox on Thursdays at 8:00 p.m. ET.
