Dark Nights: Metal #6 (2018)

As Earth-0 is falling into the Dark Multiverse, The Batman Who Laughs unwraps the bandages around his prisoner's face, showing him what he and Barbatos have achieved. Most of the heroes of Earth are defeated and being carried away by the Dark Knights. Only Wonder Woman and Lady Blackhawk still stand against the hordes of the Dark Multiverse, who have now invaded Earth. As the two heroines support each other in their fight against despair, Kendra advises Diana to clash her Eighth Metal bracelet against the Ninth Metal mace that once belonged to Hawkman, so that she may be heard by the other members of the Justice League. The idea works, as Hal, Aquaman, Mister Terrific and Deathstroke wake up and fight back against the Dark Knights. Terrific manages to convince Plastic Man to wake up from his egg form, giving a huge advantage to his allies. As Diana and Kendra fly over the battle, Plastic Man hints at the presence of a source from the Dark, which the duo spots near Barbatos himself. Diana jumps inside the hole leading to the Dark Forge, while staying linked to Kendra through the Lasso of Truth. When Diana reaches the ground, she's confronted by Barbatos's Dragon, who actually seems to start getting his conscience back as soon as Kendra arrives and calls him by his true name: Carter Hall. Barbatos promptly subdues Carter, reminding him of his role, when suddenly behind him comes Flash and Cyborg aboard the Ultima Thule, carrying with them reinforcements from other realities, including the newly discovered 53rd Earth. Diana resolves to go even deeper to find Batman and Superman, while leaving Kendra with the Lasso to deal with Carter. Kendra screams his name again, this time managing to reignite the Forge of Worlds. Barbatos isn't concerned by this, though, since he deems it impossible for them to win down in his territory. However, Wonder Woman resurfaces with Batman and Superman, all of whom are dressed in a glowing metal: the Tenth Metal, coming directly from the Forge of Worlds. Barbatos manages to strike the Thule down, but Cyborg says he's spotted the Cosmic Tuning Fork, which the Trinity can use to channel the Tenth Metal. Batman punches one of the Joker-dragons attacking them and tames him, so that he can get to the Tuning Fork faster. He then strikes Aquaman and Green Lantern with Tenth Metal Batarangs, which give them the same armor as their friends. In fact, the Tenth Metal is the prime constituent of the Forge of Worlds, meaning it is pure possibility. Meanwhile, Doctor Fate leads a team tasked with freeing everyone from the Fork. As Barbatos watches all of this unfold, he decides he'll use the final measure to definitively lower the Earth into darkness: simply scream out his anti-music. Before he can build up his cry though, Carter Hall rises from the Forge and attacks him. Barbatos, enraged, calls for the help of The Batman Who Laughs, who's now freed his prisoner from his bandages: he's the Over-Monitor, who's only starting to recover from the last Multiversal Crisis. The final plan is to destroy everything by colliding the Over-Monitor's positive energy, the Anti-Monitor Brain's negative energy, and The Batman Who Laughs' dark energy. That way, nothing but darkness will ever exist again. Suddenly, Batman turns up behind Who Laughs, but his armor isn't working in the enemy's cave because the dark energy cancels it out. The two Batmen fight until Who Laughs shoots Batman in the abdomen, saying he's the one winning because he's free from Batman's moral code. Unexpectedly, though, Who Laughs is shot himself in the back by... the Joker, who for once sides with Batman. As Laughs is prepared for anything Bruce Wayne would be prepared for, he's surely not prepared for a team-up with his own arch-nemesis: as he approaches the lever that will activate the machine, Who Laughs, realizing his position, starts laughing maniacally. He's assaulted by the Joker, while Batman runs away with the Over-Monitor. Outside, the Justice League, armored with Tenth Metal, manages to defeat the remaining Dark Knights, while Barbatos has subdued Carter once again. Diana throws a piece of Tenth Metal at Kendra, who grabs it and flies through Barbatos, ripping a hole in his chest. While Barbatos is down, Batman arrives with the Over-Monitor, who says they don't need the antenna to raise the Earth back up. Since every living thing has trace amounts of Tenth Metal in it, they can use the spark retrieved from the Forge to connect the traces in everyone on Earth, reveal a path out of the dark, and raise the planet as one. The League unites in an embrace and they let the power of the Tenth Metal flow in everyone. The power spreads across the Earth, putting it back in its proper place and destroying Barbatos's power. On top of that, it lets them reach the Source Wall, the extreme limit of the Multiverse, and shatter it.
