[12] In 2004, it returned to the all-reprint format with a Weird Secret Origins special featuring Doctor Fate, the Spectre, Animal Man, Enchantress, Metamorpho, Congorilla, El Diablo, and Bizarro World.

The first issue featured the origins of Superman, Supergirl and the Dick Grayson version of Robin.

[14][15] Additionally, there was a belated Secret Origins 80-Page Giant issued in 1998 (ISBN 1-56389-440-8), that focused on the members of Young Justice.

The focus was on DC's major characters: the origins of the Justice League of America (from #32), the Flash (Barry Allen, from Secret Origins Annual #2); Green Lantern (Hal Jordan, from #36); J'onn J'onnz, the Martian Manhunter (from #35); and Superman (from The Man of Steel #6).

Beginning with #37, each issue of Countdown featured the origins of a supervillain, written by Scott Beatty.
