SPOILER WARNING: The following article contains major spoilers for Dark Nights: Metal #6 by Scott Snyder, Greg Capullo and Jonathan Glapion, on sale now.
DC Comics' wild, multiverse-spanning Dark Nights: Metal event has now concluded, and its final issue provides a revelation that gives a little more meaning to the series' title.
From the start, Scott Snyder and Greg Capullo's nightmarish story has centered around the various cosmic metals of the DC Universe, among them the long-known Nth Metal, now also referred to as the Ninth Metal. Issue #4 of the series also revealed the existence of the so-called Tenth Metal, as revealed to Batman and Superman by Dream, aka The Sandman.
The series has shown that this newly-unveiled material consists of nothing less than the very substance of the multiverse's creation. Need, this "metal" is the raw material used in the Forge of Creation, where the various worlds of the multiverse are hammered out to populate the array of worlds known as The Orrery. This issue, though, reveals that the Tenth Metal is hardly a new discovery, and in fact has played a significant role in past DC Comics continuity.
Of Course! The Tenth Metal is Also...
Any substance that's at the center of all creation is clearly one that's been utilized by the gods themselves. Such a material has already long been in place in the DCU – Carter Hall's journal states that the Tenth Metal is revealed to be another moniker for Element X, long part of the technology wielded by The New Gods. It's a correlation that's cleverly established by Snyder, as the element is one already associated with godly entities, just as the Tenth Metal was shown to be in Metal #4.
And "X," of course, being the Roman numerical equivalent of ten, meets halfway Snyder's earlier extrapolation of "Nth" into "Ninth." If nothing else, Metal establishes a connection between two elements that happily ignored each other throughout their existence in the DCU. Yes – Nth Metal is an impure form of Element X, an exciting revelation for any continuity buffs who also dabble in metallurgy.
