Home to a Superman that debuted in 1938 and a Batman that first appeared in 1939. Unlike many of the worlds of the Multiverse, time passes on Earth 38 as it does on Earth Prime; its Worlds Finest team and other heroes aged over the course of passing decades, and eventually ceded their roles to their successors and children, beginning a heroic legacy that would continue well into the 30th century.
Knight-Wing (grandson of both Superman and Batman), as well as potentially other heroes of this Earth, joined in the battle for the Multiverse against the forces of The Gentry.
