Spoilers for Dark Nights Death Metal: Rise of the New God #1 ahead!
DC’s Death Metal event has resurrected the New God Metron just in time to play a critical role in saving the Multiverse. In Dark Nights Death Metal: Rise of The New God #1 - by writer James Tynion IV (Batman) and artist Jesus Merino (Wonder Woman) - a mysterious representative from outside the Multiverse called The Chronicler revives Metron and what Metron tells him could turn the tide of the battle against The Batman Who Laughs, now endowed with omnipotence and infinite power, essentially making him a god.
Metron was created by Jack Kirby in 1970 and initially appeared in DC’s Fourth World titles. Usually depicted as riding the cosmos in his Mobius Chair, Metron functioned as an observer of the multiverse, occasionally getting involved, but always maintaining a cool and calculated demeanor. During the New 52 era, readers learned Metron was not the original possessor of the Mobius Chair. At one time it belonged to the villainous Anti-Monitor. Metron was seemingly killed by Doctor Manhattan in Justice League #50, but now with the Multiverse on the verge of collapse, he's returned.
The issue opens with The Chronicler, a mysterious representative from the Omniverse (a larger group of multiverses) arriving to observe the end of this multiverse. Initially keeping a cool and detached air about him, he quickly realizes that of all the Multiverses he’s observed, this one is different thanks to the heroes and villains residing in it. The Chronicler wonders why a universe of such powerful beings is headed toward destruction and what could have gone wrong. His search for answers leads him first to Roger Hayden, aka The Psycho Pirate, notable for being one of the few DC characters to remember every Crisis event. Not satisfied, Chronicler then goes to Brainiac 5 of The Legion of Super-Heroes, but still does not find an answer. His quest ultimately leads him to revive Metron, a being truly powerful enough to have the answers he seeks.
After bringing him up to speed on what has happened, Metron appeals to The Chronicler for help, noting that the Chronicler is several degrees above him in power levels. Metron tells him of his days as a passive observer, and how he played his part in the cosmic drama. The issue ends with Metron showing The Chronicler the history of the Mulitverse.
The issue makes several mentions of how powerful The Chronicler is, being a representative of the Omniverse. It is not too much of a stretch to believe that he may be more powerful than both The Batman Who Laughs and Perpetua. Metron was wise to point out the similarities between himself and The Chronicler, as this appeal may draw The Chronicler, and others like him, into the battle. With such powerful entities in their corner, the heroes of Death Metal just may finally have a chance against The Batman Who Laughs and the forces of the Dark Mulitverse
