8 Batman Villains Who Haven't Appeared In A Movie Yet

When you look at the list of Batman villains, you start to notice that a lot of them are twisted reflections of various parts of Batman's character. Joker is the chaos to Batman's order, Two-Face is a twisted version of Batman's sense of justice, Scarecrow reflects Batman's use of fear, etc.

But Prometheus is perhaps the most literal interpretation of that philosophy, as he is pretty much the reverse-Batman. Growing up, Prometheus was raised by his parents, who happened to be criminals. One day, the police tracked them down, and his parents forced the cops into a shootout. Prometheus' parents were killed right in front of him as a result, traumatizing him and motivating him to travel the world in order to learn how to be the world's greatest assassin.

Now, Prometheus hunts down and kills any police officer or authority figure he can find, causing him to clash with Batman more than once. He's a bit obscure in comparison to other villains, but he's definitely one that could definitely fit into a gritty Batman film.
