There have been some rumors that The Man of Steel and Justice League are going to take place in the same continuity as Nolan's Batman trilogy, but I don't see this happening because Warner would be giving up future Batman sequels. There would be no going back to bank robbers and terrorists once you drop aliens like Superman and Darkseid into the world. The next Batman film begins with Robin Blake becoming the new Batman, Scarecrow on the loose, and Gordon waiting beside the new bat signal. The Suit: The new suit that Blake creates; with the help of Lucius Fox, should reflect how he works differently from Bruce Wayne. Robin isn't the physical machine that Bruce Wayne was; even with the exoskeleton technology that Bruce employed in Dark Knight Rises. Robin's Batman should be about stealth and flexibility. The body of the suit should be a stretchy material to allow for better fight scenes. As in the Batman Beyond series, the face should be entirely covered and the memory material created in Nolan's continuity should be built into the arms and back of the suit and deployed as a wing. The Villains: There would be three villains-- Scarecrow, Riddler, and Penguin The Scarecrow character serves as a metaphor for the terrorist in his obsession with fear. The Riddler, however, would be misconstrued as a terrorist by detonating an EMP, descending the city of Gotham into darkness on Halloween (with references to The Long Halloween story and the real life blackout caused by hurricane Sandy in 2012) when in fact he/she is planning a huge heist (or some other crime) and the blackout and chaos that follows are purely a distraction. It would draw a contrast between a terrorist and someone who does something for money or other gain. Penguin's role is simple-- he is the marriage of the organized criminal and politician; two different character types in the background of all three of Nolan's previous Batman films. The Penguin's motive should be to achieve the office of mayor under the pretense of bringing security (read, Brother Eye) to the city. He could be in league with The Riddler or he could simply exploit him; as well as Batman, to rise to power and profit. In a potential sequel, the Penguin would have made a police state of Gotham, with cameras everywhere and cops using armored tank-like cars. It would be about the escalation that Gordon alluded to at the end of Batman Begins. The Cast: I would cast Javier Bardem The Penguin, and Cate Blanchett as The Riddler (never confirming the character's sex).
