Dial H for Hero
Dial H for Hero is a comic book feature published by DC Comics about a magical dial that enables an ordinary person to become a superhero for a short time, such as an hour, by selecting the letters H-E-R-O in order. Each time it is used, the dial causes its possessor to become a superhero with a different name, costume, and powers. These superheroes are usually new, but on one occasion the dial caused its user to become a duplicate of Plastic Man. Some versions of the dial, like the original, contain additional letters, allowing other kinds of transformations. The title of the series is a play on the title of the 1954 American crime mystery film directed by Alfred Hitchcock titled Dial M for Murder.
