In the second issue of Dark Nights: Metal (the fourth overall, counting the two Dark Days specials), the Justice League goes up against Batman (again), with the Leaguers getting more than they expected when he's finally caught. There's fewer groundwork-laying and more actual story, but still lots to discuss.
Dark Nights: Metal #2 was written by Scott Snyder, pencilled by Greg Capullo, inked by Jonathan Glapion, and colored by FCO Plascencia. We're guessing that Steve Wands lettered it, but he's not credited in our copy. Dave Wielgosz is the assistant editor, and Rebecca Taylor and Eddie Berganza are the editors. [Note: We're not counting the two-page credits spread in our page number references.]
Let's Give Krona A Big Hand (Page 1)
Narrator Carter Hall is recounting the classic DC multiverse origin story from October 1965's Green Lantern #40, written by John Broome and drawn by Gil Kane. There, we learned that against the wishes of his colleagues, the Oan scientist Krona created a time-viewer that would let him see the origins of the universe. Consequently, the viewer showed him a giant hand casting whole galaxies across the limitless void. However, in addition to signaling six million weeks of winter, Krona's experiment unleashed evil into the universe, and the Oans (who naturally felt responsible) began creating galactic police forces to fight said evil.
When Marv Wolfman, George Pérez and Jerry Ordway revisited this tale in October 1985's Crisis On Infinite Earths issue 7, the real effects of Krona's experiment became clearer. His live look-in at the first moments of creation had also somehow created a) the infinite positive-matter Multiverse, b) the singular Antimatter Universe and c) their avatars, the Monitor and Anti-Monitor.
Largely put on the proverbial shelf for 20 years after COIE ended, the Monitors (now plural) got dusted off about ten years ago for the buildup to Final Crisis, and the last Monitor (Nix Uotan, whose name anagrams to An Ion Tux) starred in Grant Morrison and friends' Multiversity. Arguably the Anti-Monitor has had more exposure, being featured in a few high-profile Geoff Johns-written storylines: 2007's Green Lantern arc "The Sinestro Corps War", 2010-11's Brightest Day miniseries and 2015-16's Justice League epic "Darkseid War."
We'll get back to "Darkseid War" before long, but let's pause a moment to reflect on how this might relate to the Dark Multiverse. Basically, if the Dark Multiverse is the dark-matter equivalent of the universe we know, it must be at least as old, if not older than, our universe. In fact, it might even be older. Thus, we're thinking that when Krona's experiment did its dirty deeds (dirt cheap, since this is Metal), all of those effects pulled something from the Dark Multiverse. That would make the infinite Multiverse itself a microcosm, as it were, of the Dark Multiverse's infinite potential. By extension, the Antimatter Universe would be a relatively pale imitation of said potential, and that would be saying something.
