Big Bang Comics was comic that homage the Golden and Silver Age of Comic Books. The comic was originally published Caliber Comics. The series was cancelled and picked up by Image Comics. Now, the comic is independently published. The characters for the series are homages to various Golden Age and Silver Age superheroes. The Silver Age stories took place on Earth-A, but the Golden Age stories took place on Earth B. Some characters of note are Ultiman (Superman homage), Knight Watchman (Batman) and Dr. Weird (Mr. Justice). A notable feature of Big Bang Comics is its use of metaficiton. In the Big Bang universe, there are several imprints (that in reality never existed) that published the characters. This was used to give add more depth and development to the series' characters.
