Arkham City Bio
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 had committed manu, crimes often themed around the book that inspired him and his love for hats and head gear, going so far as to implant his hats with mind-control chips to amplify his hypnosis skills.
Above all other headwear, however, he covets Batman's distinctive cowl and will stop at nothing to acquire it.

Additional Information
Tetch's obsession with Carroll's novels often leaves him quoting and making references to the books spontaneously, and sometimes even fails to discern between these stories and reality. His fascination with hats can also be severely extreme; when in the Secret Six, he would not eat a piece of food that does not have a hat on it, and refused to look at his naked teammate Knockout as she wasn't wearing any headgear. His quest to find Alice has pedophiliac tendencies, hunting down young girls (in one case, a young Barbara Gordon) and forcing them to dress for a Tea Party - though most will never leave alive.

Possible role in Arkham 3
After a series of kidnappings that included criminals, members of the public certain former Batgirl, Batman follows clues that lead him to the abandoned maze in Robinson Park. Batman would have to fight his way through brainwashed Wonderland characters to get to the centre of the hedge maze to find Mad Hatter having a tea party with a sedated Oracle (dressed as Alice). As Hatter sees that Batman is winning, he changes tactics and flips a 'suicide switch' on the brainwashed captives. Batman would then have stop them from hurting themselves by removing the weapons from their hands, stop them from jumping onto spiked ornaments and once close enough, remove the mindcontrol headgear.
