Earth-Forty



Earth-Forty is the official name of the oldest official alternate reality of DC comics.

History
Earth-Forty's first hero was Superboy though he was raised and worked out of Metropolis rather then Smallville.

In 1940 Billy Batson gained superpowers and took up the name Captain Thunder.

During the 1940s Batman, Superman, and Wonder Woman all had adventures during WWII. In one of them Wonder Woman first encountered a blond haired Giganta (who like her Earth-Two and Earth-One counterparts was an artificially evolved ape).

Batman married Batwoman (Katherine Kane) and eventually retired passing the mantel of the Batman to his son Bruce Wayne, Jr. sometime in the 1960s.

It was eventually revealed that this was a hypertime reality meaning it was not effected by Crisis.
