"The interesting thing about the Man of Steel was that regardless of how extraordinary the mortals of Earth thought him to be, the Kryptonians didn’t think of themselves as super at all when they were together on their home planet. Why? Because on Krypton, everyone was strong. Gilbert and Sullivan said it best in their operetta, The Gondoliers, when the Grand Inquisitor proclaimed, “If everybody’s somebody, then no-one’s anybody.” But when a Kryptonian left the home planet and came to live with the mortals of Earth, the difference was striking."
