9. Batman/Captain America
A crossover book that's also an Elseworlds? Why, thank you very much!
This one is a Batman/Captain America team-up that takes place during World War Two. And it's a fun little throwback to that era of comic books. Plus we get the forties Batmobile, and that is always a cause for celebration for me.
Cap and Bats have a natural chemistry, and, while both are pretty one-note in their portrayals, that sort of "stock heroic white dude" persona is kind of a hallmark of golden age comics, so it's understandable. Bucky and Robin bounce off each other well as respective teen sidekicks, and Red Skull and Joker complement each other well as villains.
Of course, the most notable scene in the book is the one in which Joker discovers that Red Skull is a Nazi and loses his mind over it. The idea that the Joker, even as bad as he is, still can't stand the Third Reich, is kind of great.
