Tom King is out. Never read his Batman run. Judging from the response to it I'm getting the feeling that his run was too deconstructionist? So if he were to come to Marvel what book would be perfect for him?
I'm thinking Moonknight
Why.
1. It's in his wheelhouse. Caped figure hiding in shadows? Throwing sharp objects at people?
2. Characterization doesn't matter only the costume, and I don't mean the Mr. Knight one. Search your feelings you know it's true.
3. The bar is very low. Before even writing one word King will instantly be a top five Moonknight writer. After one issue, top three. If his run manages to go there years he will be the best Moonknight writer ever.
4. If Moonknight is ever made into a movie his run will probably be used for the sequel. Synergy!
