Mad Hatter

Bio
Jervis Tetch is a big fan of Alice in Wonderland, so he turned himself into his own version of the Mad Hatter. He uses tech he made to send signals the headwear (typically hats) that let him control the mind of the person wearing it.

History
When Miss Masquerade visited his manor pretending to be Alice, Jervis drugged her tea and then once that took effect put one of his mind control devices on her head.
