Obsessed from a young age with Lewis Carroll's Alice in Wonderland, Jervis Tetch, a brilliant neuroscientist, embraced a delusion that he was the incarnation of a character in the story, the Mad Hatter. Using his hypnotic skills for mesmerism, Tetch as 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 plant his hats, ranging from pith helmets to bowlers, with mind control chips to amplify his hypnosis skills. Above all other headwear, he covets Batman's distinctive cowl and will stop at nothing to acquire it.
