10 Most Insane Open World Game Enemies You Must Find

Batman has a lot of incredibly creepy villains. But, to be fair, as a superhero, that comes with the territory. The Batman: Arkham series flawlessly captured the Caped Crusader's array of crazy bad guys. Still, one of the absolute scariest - but most exciting - was the demented Professor Pyg, who featured as a Most Wanted criminal in Batman: Arkham Knight.

This opera-loving psychopath was a deranged scientist who would kidnap people and perform invasive surgeries on them. These procedures turned them into his personal brand of mindless servants known as Dollotrons. As if that wasn't bad enough, he also murdered anyone he took who didn't match his perfectionist standards.

Getting to confront this villain required you to complete a slew of deep tissue scans on Pyg's victims, who were strewn about Gotham in monstrous displays. The brutality of these investigations really set you up for the eventual horrorfest showdown with this enemy.

The encounter with this obscure yet captivating DC villain had you battling against his Dollotrons and being forced to listen to the terrifying voice performance from Dwight Schultz. It's one of Batman: Arkham Knight's best Gotham's Most Wanted missions - if you like a bit of the spooky stuff.

This monster absolutely fits the insane enemy bill in the most literal of ways.
