Mad Hatter
This would be yet another secondary role for Andy Serkis, but as the Mad Hatter, he’d be able to surprise audiences when going against the Batman. Despite his small stature, this villain went toe-to-toe with the Dark Knight in the comics.
The Mad Hatter is a brilliant neuroscientist, and could serve as an underling for the main antagonist of the film, using his mind-controlling devices to provide the necessary edge.
On the other hand, if Matt Reeves decides to use just one major villain in the movie, The Mad Hatter could be a minor criminal who’s subdued by the main antagonist prior to attracting the Caped Crusader’s attention. This could work pretty well, especially given The Hatter’s history in the comics with other villains from Batman’s rogues gallery.
