Common costume features
A superhero's costume helps make him or her recognizable to the general public both within the comic-book reality as well as the reader's reality. Due to the serial nature of comics, the style and appearance of the title character often changes with the introduction of a new artist. To make the title character immediately recognizable from other characters within the title or from competing characters in other comic-book titles it is practical to make the costumed character flamboyant and therefore more iconic. Costumes are often colorful to enhance the character's visual appeal and frequently incorporate the superhero's name and theme. For example, Daredevil resembles a red devil, Captain America's costume echoes the American flag, Batman resembles a large bat, and Spider-Man's costume features a spider web pattern. The convention of superheroes wearing masks (frequently without visible pupils) and skintight unitards originated with Lee Falk's comic strip hero The Phantom.
