Mad Hatter (Batman: Arkham Origins)

"Welcome to Wonderland, Batman!"

- Mad Hatter

Obsessed from a young age with Lewis Carroll's book Alice's Adventures in Wonderland, Jervis Tetch, an expert hypnotist, embraced a delusion that he was the incarnation of a character in the story, the Mad Hatter.

Using his skills for mesmerism, the Mad Hatter has committed many crimes, often themed around the book that inspired him and his love of hats and headgear, going so far as to implant his hats with mind-control chips to amplify his hypnosis skills. The Hatter was also a prolific rapist and murderer, brainwashing countless women who he believed to be "Alice" and later murdering them when he was finished with them.

Batman: Arkham Origins
The Mad Hatter appears as a side mission on Gotham's Most Wanted List. Shortly after the Joker's robbery of the Gotham Merchants Bank, Batman encounters three henchmen in rabbit masks, singing that he is invited to the Mad Hatter's party. After they collapse, Batman receives a message from the Mad Hatter, saying that he's kidnapped a girl which he calls "Alice". Batman heads to his lair in the Bowery and confronts Tetch, but Mad Hatter traps him with his hypnosis, making him end up in "Wonderland". Batman manages to navigate through "Wonderland" and break free of Tetch's control, only to find him threatening to kill "Alice". Batman throws a Reverse Batarang at him and knocks him out. If Batman returns to his lair, he will notice Tetch still unconscious, and he will notice the girl crying after what she has gone through.
