Alfred Pennyworth has been one of the most prominent supporting characters in バットマン since the early 40's. At first, バットマン was on his own, but he quickly got Robin as a sidekick and Alfred as a butler. Like the Batcave, it's been reported that Alfred was created for the original movie serial. He quickly became a character in the comics. Aside from バットマン himself, Alfred is the only character to appear in all of the official live action バットマン films. Commissioner Gordon was also in all of them, until 2016's バットマン V スーパーマン excluded him.
