Mad Hatter

Jervis Tetch, aka Mad Hatter, according to his file at Arkham Asylum, is 'obsessive-compulsive, and highly delusional. He's got an immature self-image, so he identifies more with children than adults. Oh and he's a genius, too.' He used to be a research scientist at Waynetech, until his delusional fixations got the better of him. His idolation of the works of Lewis Carroll has driven him to take the appearance of the Mad Hatter from Alice in Wonderland, which would be harmless, but for the fact that Jervis Tetch is one of the foremost neuroscientists in the world, having developed hardware that can control the brain and create a hypnotic state. The mind control devices are usually kept in his hat and on 10/6 cards which he places on his unwilling victims.
