National Superman Day is celebrated every year on June 12 to honor the creation of the famous superhero, fondly known as the "Man of Steel." DC Entertainment declared June 12 as Superman Day in 2013. The day was initially called "Man of Steel day," but was later changed to "Superman Day." The superhero was created for DC Comics by writer Jerry Siegel and artist Joe Shuster, and first appeared in Action Comics, no. 1, in June 1938. The character was initially supposed to be a bald telepathic villain, who wanted to dominate the world, but the writers instead created a superhero character wearing a blue uniform with a flowing red cape.
