“More powerful than a speeding bullet. . .” represents the persistent and frequently used “faith statement” that represents the identity of “Superman,” the name given him by early reporters on earth. As he walks among us, he is familiarly known as “Clark Kent,” the name given him by his adoptive family. His original name at birth, however, was Kal-El (Hebrew “Voice of God”) on the planet Krypton. This triple identity and the “faith statement” were first used in the Superman radio serials and Max Fleischer animated shorts of the 1940s as well as the TV series of the 1950s.
