Tweedledum and Tweedledee are a duo of supervillains appearing in comic books published by DC Comics, primarily as enemies of Batman. Dumfree and Deever Tweed made his live-action debut in the third season of Gotham, portrayed by Adam Petchel and Happy Anderson. Publication history Tweedledum and Tweedledee first appeared in Detective Comics #74 (April 1943), and were created by Bob Kane, Jerry Robinson and Don Cameron. Fictional character biographies Dumfree Tweed and Deever Tweed are cousins who resemble each other so closely that they are often mistaken for identical twins. The pair are known as Tweedledum and Tweedledee, both as a play on words on their real names, and because they closely resemble Sir John Tenniel's depictions of the characters in Lewis Carroll's Through the Looking-Glass. The two Tweeds always conduct their criminal activity in partnership with one another. They prefer to mastermind criminal schemes and let their henchmen carry out any necessary physical activity. The Tweeds will often use their extraordinary resemblance to trick their opponents into thinking there is only one of them. Tweedledum and Tweedledee first encountered Batman and Robin when they began a crime spree in Gotham City. Batman and Robin have fought against the Tweeds and have overcome them on subsequent occasions. The pair makes an appearance in Arkham Asylum: A Serious House on Serious Earth as inmates in Arkham Asylum. In this incarnation, they appear attached to each other by a pair of electroshock helmets, with Tweedledum representing the right half of the brain, and Tweedledee the left. Although Tweedledum and Tweedledee are most often depicted as being the leaders of their own criminal organization, they sometimes are reimagined as the henchmen of the Joker. In a shoot-out with the GCPD during War Games, Dum is shot in the head. During the Infinite Crisis, Tweedledum and Tweedledee appear as members of Alexander Luthor, Jr.'s Secret Society of Super Villains. Joker refers to them as "Tweedledee and the new Dum" implying that the original Tweedledum is either dead or still incarcerated. It was later confirmed in Detective Comics #841 that Dumfree Tweed had died and his twin brother Dumson Tweed had taken his place. The new Tweedledum and Tweedledee were part of the Wonderland Gang. Originally believed by the public to be run by the Mad Hatter, it was revealed that the Tweeds really ran the gang using one of Tetch's own mind control devices
