"Let's face it, it's beyond mythological to have Superman and our new Batman facing off, since they are the greatest super heroes in the world," Snyder said.
At a Comic-Con panel exploring Superman's history, and his future, a team of creators who have written the character, and actors on the shows and films about him, spoke Saturday about Superman's relevance and invulnerability to obsolescence.
"Like Batman, this is a very malleable character that can change and still be his core influence," said writer Grant Morrison, whose take on the character in the pages of "All-Star Superman" was critically lauded.
Morrison said that as times change, so too, has Superman, serving as a mirror not to a Phantom Zone, but to contemporary real life.
That was a nod to the darker tone in "Man of Steel," a grittier take on not just Superman, but his upbringing and influences, too.
"He's just reflecting a general tendency, as he always does. Superman has to reflect what people are feeling. I think it's an inevitable part of his development," Morrison said. "If he's dark now, it's because we're all a little bit dark."
With 75 years now passed, DC Entertainment co-publisher Dan DiDio said that the comics will continue their retelling of his early days, which in the New 52 universe that launched in 2011, includes a budding romantic relationship with Wonder Woman, a return trip to Krypton and more.
"Superman is such an identifier for who we are and what we are about — not just DC Comics but just comics in general," DiDio said. "He is just as strong and probably more vibrant than ever."
