Supergirl Trailer: 25 Easter Eggs And References You Need To See

13. John Byrne's The Man Of Steel

The majority of comic book fans consider John Byrne's The Man of Steel to be the definitive origin story for Superman. It featured many of the iconic moments which have since become a staple of Superman's early years and remained an official part of DC Comics continuity for decades. Supergirl wasn't included, but the trailer still pays homage to it. In the series, Superman was forced to reveal his powers to the world to save a space craft which was plummeting to Earth long before he had a costume or secret identity. Kara does exactly the same thing in the trailer, revealing herself to National City and suddenly thrust into the public eye. It's not a huge reference, but is no doubt what inspired this scene.
