A good hero is defined by their villains and the characters of the DC Universe are no different. Heroes like Superman and Batman are made great by villains like Lex Luthor and the Joker and their fights make for some of DC's best stories.
With decades and decades worth of comics, DC has a lot of villains though. While some have deservedly been forgotten (looking at you Ten-Eyed Man), there are plenty of lesser known bad guys who have the potential to be used a lot more than they currently are.
These villains have interesting powers and backstories and in a lot of cases plenty of fans, but they'll always end up pushed aside in favour of the more popular bad guys, especially when it comes to the movies.
Sure they might not be as recognisable as the likes of Darkseid and Deathstroke, but they still deserve a lot more attention than they're currently getting. And with the DC Cinematic and Television Universes bringing more exposure to minor characters, now is the perfect time to highlight them.
