[2] The Mad Hatter has been substantially adapted from the comics into various forms of media, including feature films, television series, and video games.

He has been voiced by Roddy McDowall in the DC animated universe and Peter MacNicol in the Batman: Arkham video game series, among others.

A variation of the character named Liam Crandle appeared in the third season premiere of the Arrowverse series Batwoman, portrayed by Amitai Marmorstein.

[3] Jervis Tetch is fascinated with hats of all shapes and sizes, as well as the Lewis Carroll's children's book Alice's Adventures in Wonderland and its sequel Through the Looking-Glass, particularly favoring the chapter "A Mad Tea Party".

[7] In the graphic novel Arkham Asylum: A Serious House on Serious Earth, it is strongly implied that he is a pedophile, though the book itself is a symbolic dream in Batman's mind, so this is dubious.

[8] His storylines in Streets of Gotham #4 and Jeph Loeb and Tim Sale's Batman: Haunted Knight also imply an unhealthy fixation on children, such as when he kidnaps a young Barbara Gordon and forces her into a tea party dressed as Alice, as well as kidnapping other runaway children and dressing them up like characters from Alice's Adventures in Wonderland.

Fearing the reaction of her extremely strict mother, Connie lies to her and claims she had been raped by someone on her high school's baseball team, the Gotham Hawks.

[11] In his first appearance as the Mad Hatter, Tetch attempts to steal a trophy from the Gotham Yacht Club, and begins a crime spree that ends when he is foiled by Batman while he is trying to rob spectators from a high society horseshow.

[15] During another early encounter with Batman, the Mad Hatter escapes from Arkham in time for Halloween, and makes his home in an old mansion that had been abandoned after a gruesome murder years before.

In Robin: Year One, millionaire third-world dictator Generalissimo Lee hires the Mad Hatter to kidnap a number of young girls using his mind control devices.

[18] Another plan consisted of implanting his devices in "free coffee and donuts" tickets he handed out in front of the police stations in Gotham.

Distraught at the news, Elle Littleton inadvertently tells her daughter Connie that Tetch had killed the team for her, to "avenge her honor".

[11] While working with Black Mask, the Mad Hatter implants a mind control chip directly into Killer Croc's brain, which causes him to mutate again due to the virus he had been injected with by Hush and the Riddler.

During Infinite Crisis, the Mad Hatter is first seen being roundly beaten by Argus, and then later fighting with the Secret Society of Super Villains during the Battle of Metropolis.

[20] Tetch's base of operations in Gotham City is destroyed following a search for an atomic weapon, by the former Robin, Tim Drake, and the current Captain Boomerang, Owen Mercer.

Prior to the events of Gotham Underground, Tetch falls victim to his own mind control devices at the hands of Tweedledum and Tweedledee.

[21] More recently, Mad Hatter appears in Gotham Underground #1 (August 2007), alongside Scarecrow, Hugo Strange, the Penguin, and Two-Face, who have gathered together to assist him in escaping Gotham in light of the disappearance of other villains due to the Suicide Squad and Amanda Waller kidnapping and deporting villains offworld in Countdown to Final Crisis.

He appears briefly during the final issue as the Parademons attack, and escapes the Hell Planet alive thanks to Lex Luthor's device.

In the first issue of DC Infinite Halloween Special, Hatter recounts a first-person perspective story of a small boy whose parents are murdered before his eyes by a blood-sucking humanoid bat.

In the 2008 DC storyline "Final Crisis", Dan Turpin has been approached by the Question with regards to a recent string of child disappearances related to a mysterious group called The Dark Side Club.

He is gathering a group of children together and infusing them with the Anti-Life Equation as part of his broader plan to enslave and devastate the human race.

In Final Crisis #2 (2008), Turpin discovers that Tetch played an instrumental role in assisting Darkseid in gathering the children together through the use of his mind-control hats.

Final Crisis Secret Files and Origins #1 also reveals that Darkseid's Justifiers helmets are a combination of Apokoliptic technology and the Hatter's mind control circuitry.

[volume & issue needed] Secret Six #6 (February 2009) reveals that Mad Hatter has hired the Six to break Tarantula out of Alcatraz, to deliver her as well as a "Get Out of Hell Free" card created by Neron to Gotham City.

[25] He uses his mind control technology to make a passenger train full of people commit suicide, assisted by his henchmen, the Tweed Brothers.

[28] The Mad Hatter resurfaces, selling his mind control hats all over Gotham and holding casting calls at his missile launch facility base, all to recreate a “perfect day” he had years before at a theme park with his childhood sweetheart, Alice.

[citation needed] The Mad Hatter becomes obsessed with Bruce Wayne's new girlfriend, Natalya Trusevich, and has the Tweed Brothers kidnap her.

[30] While the Mad Hatter has no inherent superpowers, he is a brilliant 'neurotechnician' with considerable knowledge on how to dominate and control the human mind, either through hypnosis or direct technological means.

This Mad Hatter first appeared in Detective Comics #230 (April 1956) by Bill Finger, and Sheldon Moldoff, and, unlike the original, was tall, red-headed, stocky and sported a gaudy mustache.

[38] The Jervis Tetch incarnation of the Mad Hatter appears in series set in the DC Animated Universe (DCAU), voiced by Roddy McDowall.
