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 the villains of the Batman.
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.
