Background Information and NotesEdit
Edison is the first character of his kind, in which Batman must reach out to outside help to build vehicles or gadgets. Harold Allnut later performed similar functions but actually lived in the Batcave. Edison seems to be the inspiration for the Earl Cooper character in Batman: The Animated Series. After the movie Batman Begins changed the Lucius Fox character from a mere businessman to genius level engineer, he seems to fill this role in all media due to his brand recognition value.
