"We see the evolution of a new Batman," Ben Affleck says. "Inspired by Superman's sacrifice, he's moved on from lone vigilante to recruiter and leader." However, co-leader may be more fitting, as Gal Gadot addresses the relationship between Wonder Woman and the Caped Crusader, saying, "In a way, they are a perfect match as partners."

The segment also features Jason Momoa, Ray Fisher and Ezra Miller, who, wearing a hot with a lightning-bolt logo, introduces himself simply as "Flash, the Fastest Man Alive." Clearly he's having fun with the role.
