Batman: Gotham Knights was a monthly, fictional comic book series published by DC Comics. The original intent of this book was to feature the exploits of Batman and his extended family - Alfred Pennyworth, Batgirl, Nightwing, Robin, Oracle, Catwoman, etc. The latter section of the run, however, came to focus much more upon his enemies. The series also featured the popular "Batman: Black and White" back-up strip, which allowed various artists with widely varying styles to do their take on the Dark Knight in a black and white format. These back-up strips are also collected in trade paperback form. Contributors to this section include Jim Lee, John Byrne, John Buscema, Eduardo Risso, Jordi Bernet, José Luis García-López, Kyle Baker, Dave Gibbons, Gene Ha, Gene Colan, Enrique Breccia, Claudio Castellini, Dick Giordano, Christian Alamy, Jason Pearson, Mike Wieringo, Alan Davis, Chris Bachalo, Denys Cowan, John Watkiss, Mike Kaluta, and Whilce Portacio.
