Jervis Tetch is a delusional criminal who believes he is the reincarnation of Alice in Wonderland's Mad Hatter. He uses his background in hypnotist to commit crimes, and even has a device in his hat that aids with this (how? No idea). In the game, he is a side mission where Batman has to rescue a woman Tetch has kidnapped and dressed up as his "Alice". Later, Batman fights on a massive clock while battling goons with White Rabbit heads. It's pretty creepy! He also has a Most Wanted DLC mission in Arkham Knight. I like his design, with all the patchwork coat and generally grubby look. He's kind of perfect for who he is! I rarely enjoy appearances by him in comics, shows or films but in this case it was a fun little side story.
This figure is a pretty good representation though aside the articulation, I wish the hat fit better. He is the Mad Hatter after all!
