Hatter, a.k.a. Jervis Tetch, is a Bat Family villain. His gimmick is mental manipulation, usually through little devices that allow him to control the minds of his victims. That's the only reason why I don't think he'll appear just yet. They just did a mind control storyline, they probably won't be so keen to do another.
