10 Villains Better For Ben Affleck’s Solo Batman Movie
7. Clayface
Another one reliant on effects work, but again if they can pull it off then Clayface could be a superb foe for the solo Batman outing.
The character has never been adapted for a live-action film before, so there's a chance here to do something really unique, both in terms of a villain relatively new to audiences and in terms of the challenge he'd pose to Batman.
His size and power mean he's a considerable enemy for Bats to try and fight as it is, but he becomes truly special by the way he can shape-shift and mimic others, so he could take on the identity of other Batman villains, or the mental challenge of someone close to Batman. Clayface provides a great dual test that means he'd be capable of really testing Affleck's Batman, and be visually interesting and different at the same time.
