Fan Casting Batman in Ben 10/Justice League: The Series

In most of his incarnations, Batman is a dark and grim hero with a personal vendetta against criminals. Batman has sworn to rid Gotham of the criminal elements that took his parents from him. He is very paranoid and obsessive, but Batman has proved to have a great love for humanity and created an oath of vengeance that is tempered with the ideal of justice, that killing does not make him any better than the criminals he fights. He's a detective, able to see things others could not see.
