Earth-36 is based on Gary Carlson's Big Bang Comics. Carlson created Big Bang when he felt that modern DC Comics had become too adult-oriented, and he was nostalgic for the more innocent stories of his childhood. Optiman first appeared in the same assemblage of Superman analogues as Savior, Supremo, and Guardsman.
Earth-37 is the home of many stories written by Howard Chaykin, one of the most prolific Elsewords writers of the 1990's. These stories include BATMAN: THRILLKILLER, TWILIGHT, and IRONWOLF.
