This was a four-issue limited series set in an alternate reality outside that of the mainstream DC Universe designated as Earth-22.

The setting for Kingdom Come took place some twenty years into the future of the year that it began publication. The older, more established super-heroes had gone into retirement, giving rise to a new generation of anti-heroes, who did not uphold the same noble values as their predecessors.

Mark Waid and Alex Ross wrote Kingdom Come as an indictment against the growing trend of violent anti-hero archetypes that had sprung out of the early 1990s.
