75 of the Dark Knight's greatest allies and villians to celebrate 75 years of Batman
24. Mad Hatter
The Mad Hatter, created by Bill Finger, Bob Kane, Lew Schwartz and Charles Paris, is an odd little figure in Batman history. He debuted during the Golden Age but then didn’t appear again until the 1980s (he was even replaced by another Mad Hatter for a time). It seemed like he was poised to be just a one-off villain.
