When Hercules and the God Squad needs to make their way to the Skrull gods' realm during the "Secret Invasion" storyline, they require a map of the Dreamtime, and barter with Nightmare for it. Nightmare agrees, in exchange for access to the fears of the five gods; however, he actually intends to use these divine fears to conquer the world. Hercules and the others escape his realm, having stolen the map via trickery as Mikaboshi had created a shadow duplicate of himself to fool Nightmare. Nightmare summons up an army of monsters to attack them, but they escape.
