Jervis Tetch, also known as the Mad Hatter, is a delusional and obsessive man inspired by Lewis Carroll's Alice in Wonderland. A brilliant hypnotist turned criminal, he uses his hypnotic skills and his pocket watch to manipulate others. His fixation on finding 'Alice' drives his actions, often leading to dangerous and erratic behaviour. Tetch's personality is marked by madness, cunning intellect, and a love for hats and headgear. He can be very sweet and whimsical but also highly unstable.
