There are a few aspects of Batman that remain consistent. He is the secret identity of the wealthy Bruce Wayne, (usually now called a billionaire because of inflation). He has a butler, Alfred, who knows his identity and who took part in raising Bruce after the murder of his father and mother. Batman has no superpowers, but he’s intellectually gifted and makes use of gadgets, science and well-honed fighting skills and physical strength to defeat his enemies.
Batman’s origin story is the departure point for many different renditions of the character. In initial versions, he’s the inscrutable almost anti-hero, and in others, such as the 1960s television series, he’s a much more levelheaded guy living in a much less corrupt city. The 1960s series leaned heavily on camp, and prompted some to think of killing off the character forever. However, interest in this superhero revived in the 1980s, first with famous graphic novelist Frank Miller’s limited comic book series The Dark Knight Returns and then with the 1989 Tim Burton film. Both Miller and Burton were resolved on dispatching the image of the law-abiding television series superhero to return to his much darker beginnings, though Burton did so with considerable humor.
