First, there are a few visual cues hearkening to Kingdom Come's relation to other mythologies. The redesigns of both the Flash and Green Lantern are of significance. The Apocrypha to Kingdom Come says the Flash "may hold all the spirits of the previous incarnations" (Waid Kingdom 220); he has become more of a supernatural blur than superhuman hero. In fact, on page 132, he is actually shown to be literally two place at once, "too fast to be contained by one plane of existence" (Waid). More strikingly, this Flash has reclaimed the winged helmet worn by the original Flash, Jay Garrick, as a tribute to the Olympian god of Speed, Mercury. His return to wearing the petasus reconnects Flash and alludes more strongly to this mythic origin. Likewise, this Green Lantern has adopted an Arthurian motif; the Spectre tells McKay that Alan Scott, the original Green Lantern, has fashioned his own orbiting castle in the sky and "commands a lonly throne...ever vigilant, ever waiting for signs of threats extraterrestrial" (41). This new suit of armor for the Green Lantern also comes with its own green lance, further cementing his image as a knight of the realm, defender of the kingdom. In fact, it is his conference room where the Justice League gathers, with Superman standing at the head of the circle, much like the Round Table of Camelot.Both the Olympian and the Arthurian fight side-by-side on the League. Even the newest incarnation of Hawkman appears to be more of a supernatural Native American animal-god than masked adventurer.

As mentioned with Superman, Christian mythos is prevalent as well. The title of Kingdom Come itself as well as the book's opening lines are a references to the New Testament. In the book of Matthew, Jesus Christ is recorded as having said: "Our Father in heaven, hallowed be your name. Your kingdom come. Your will be done, on earth as it is in heaven" (6:9-10). In fact, the promotional material for Kingdom Come seizes upon that reference; the poster displays dark portraits of Wonder Woman, Batman, Captain Marvel, Superman, and McKay all in the palm of a looming Spectre with a caption reading, "The Dreamer. The Thunder. The Bat. The Eagle. The Angel. Whose Will Be Done?" (Waid Kingdom 228). A biblical reading of Kingdom Come holds up in many other ways. The Spectre is the divine spirit of vengeance, an angel in a loose sense of the word. He comes to an aggrieved Norman McKay — modeled after Ross' own father, preacher Clark Norman Ross — at his church, Gethsemane Evangelical. This is, according to Jesse Nevin's Kingdom Come Annotations, a reference to "the garden outside Jerusalem mentioned in Mark 14 that was the scene of Jesus' agony."

Olympian, Arthurian, Native American, Christian, and even Nordic mythological echoes run all throughout Kingdom Come, leaving one to question, as I will in my paper, what connection Kingdom Come itself has directly to myth and whether there is a fabula or fabulae to which all mythologies adhere.
