Gary Carlson's first major independent comic occurred in the 1980s with a black and white title called Megaton. Erik Larsen's Savage Dragon, Rob Liefeld's Youngblood both debuted in Megaton. In the 1990s Carlson wrote Berzerker for Caliber Press; one of the first canonical appearances of a Big Bang Comics character was by the Knight Watchman in Berzerker #1. Gary co-created the Big Bang anthology series alongside artist and writer Chris Ecker. Until 2005, Big Bang published 35 issues of Big Bang through Image Comics, followed by seven "special" comics.
