There is a man, though I am hesitant to call him that...so mighty is his knowledge of the Caped Crusader/Dark Knight that he must surely have transcended into the realm of Lesser Deity by now. This Man-Deity goes by the name of Chris Sims and he has taken it upon himself to gift us lesser morals with fictional images of comic book characters, seen through the loving prism of the 8-Bit era of the NES.
I really love all of these pics, but my favorites are Archie/Burgertime and Hellboy/Castlevania.
Make sure to check out Chris's personal blog, http://www.the-isb.com/ which always has some great and amusing sequential art related information.
Or take a look at the site he happens to write for, Comics Alliance, if you like what you see posted above, they too have all manner of comic book related stories. http://www.comicsalliance.com/
