I'd love it if there was more stuff like this in the comics, not a Superman/Batgirl pairing, but just the characters showing up/helping each other out more often. They all seem so isolated most of the time, which makes sense for Batman (because he got issues and scares everyone away) but why are all the other hero's constantly trying to handle stuff on there own? Anyway this just struck me as awesome because I've been toying with a story idea where Batgirl and Nightwing get in trouble and Superman (not Batman) comes to the rescue.
