As the Batman Who Laughs reshapes the DC Universe in his nightmarish image in the crossover event Dark Nights: Death Metal, one of the most fearsome, powerful Dark Knights isn't the villain's lieutenant -- its a loyal servant to the omnipotent Perpetua. Meet The Omega Knight.

The new villain is an amalgamation of the Omega Titans that the heroes and villains of the DCU first encountered in the 2018 miniseries Justice League: No Justice, barely securing a victory at great cost. No Justice co-writer Joshua Williamson will helm a five-issue storyline in the pages of the main Justice League title, tying directly into Death Metal. The story arc features a ragtag Justice League roster confronting the Omega Knight to destroy Perpetua's main power source, which is her throne.

"The Omega Knight is Perpetua's guard for her throne that powers her and allows to destroy parts of the Multiverse. It's in the Metal-Verse but they constantly move it around and it always has this Omega Knight protector, watching over it, and what it is -- again, tying into No Justice -- it's one of the Omega Titans," Williamson explained in an upcoming interview with CBR. "Perpetua's taken them and brought them back together as this sort of Frankenstein, resurrected nightmare monster."

Led by Nightwing and Lex Luthor, the Metal-Verse's Justice League will find themselves considerably shorthanded in comparison to their last battle against an Omega Titan, a celestial invader from beyond the Source Wall that laid waste to everything caught in its path. According to Williamson, the upcoming battle against the Omega Knight, and its combined powers of composite Omega Titans, may prove to be "impossible."

"It was created in the Dark Multiverse and has been brought to protect the throne. It's an impossible challenge: You go back and look at No Justice, how much it took just to destroy one of them; one of them destroyed [Brainiac's home world] Colu, one of them came to Earth and was going to destroy Earth," Williamson continued. "And all the steps it took to try to destroy one was nearly impossible and it took so many members of the Justice League and, in this case, you don't have that, you don't have that exact same team. They have the experience of fighting one but they don't have that exact same team and so it's like what can they do to try to take on this giant, monstrous thing."

Written by Joshua Williamson and illustrated by Xermanico, Justice League #53 kicks off "Doom Metal" on Sept. 15 from DC.
