It's back to the future for Superman and the Legion of Super Heroes. The cosmos-spanning team of young heroes has been part of the DC Comics universe for almost 50 years. It has seen more than its share of changes, with a series of updates and reboots. Now the Legion has a new home: the world of Saturday-morning cartoons."Superman is our entrypoint character, as they like to say," said James Tucker, a producer on the show. This, though, isn't yet the Superman we all know. He's a young hero still learning about his powers. The Legionnaires want him on their team, but they have to be careful in their dealings with him, Tucker said.
