Alright, well, MK vs. DCU is happening, whether we like it or not. However, I'm sure a whole lot of MK fans out there are still scratching there heads and going, "Okay, there's Superman, Batman, Wonder Woman.... and who else?"

This thread is basically a bit of a database for some of the more important, but lesser known, heroes and villains of the DC Universe. Please, please feel free to add any additions you can think of, but I figured I'd take the initiative to make a more comprehensive database in one thread rather than leave it purely to speculation and random google searches.
