The thing with Bendis is I think they need to create a space just for him in the DCU with some minor characters he can play with. I know he’d be great on Batman, but both Batman books are occupied right now. Batman’s kind of too big for Bendis type books. So maybe he’d be better with Nightwing, or even a Commissioner Gordon book. Gotham Central, or just a book on Gotham itself with Batman only a rarely occurring character. The idea of taking what he did with Malev in Daredevil and writing something like that for Gotham would be great.
There’s characters he shouldn’t touch. In the same way he kind of knew he should stay away from Hulk & Thor, he need to stay away from Superman & Green Lantern. Bendis should just stay away from space. Which means I think he should avoid JLA. It’s not his thing. And I don’t want him near Joker - we don’t need a Gilmore Girls type exchange with Joker mixing in pop culture references.
He needs to find his Daredevil, Jessica Jones, Cage and Spiderman. I could see him making Cyborg an interesting property. I’d give him Talia Al Ghul, Nightwing or Damien. While he’d be great on Blue and Gold, I don’t think they part of DC’s plan. He’s clearly going to want Green Arrow - that’s his type of character.
By this point Bendis must know himself pretty well. DC want to take the most advantage of him. And maybe the biggest advantage is elevating a C lister to an A lister and creating a new property everyone is excited about. That’s where I’d use him.
