Reverse Flash and Earth 90 Flash ran around Gotham of Earth 14 at phenomenal speed, causing confusion for Gothamites. Batman spotted the red and yellow streaks of lightning on the streets below and went to investigate. Reverse Flash pinned Earth 90 Barry down.
"You've never faced me before, Barry Allen," Thawne said, "This world will end soon, and it will all be thanks to you. The Anti-Monitor will see to it.
Upon a seeing Reverse Flash ready to impale Earth 90 Flash with a vibrating hand, Batman threw a batarang at him.
"What's that supposed to do?" Reverse Flash asked, as he was momentarily caught off guard.
"This batarang's been laced with nanites, courtesy of Wayne Enterprises," Batman said, "They're disabling your speed. You're not gonna be running around for quite a while."
"I don't need speed to take you down, caped freak!" Thawne yelled, as he started fist-fighting with Batman, but Batman knocked him out with a swift punch to the jaw.
"Good job, kid" Earth 90 Flash said, as Batman helped him up.
"Yes, most impressive indeed," came a familiar voice. Batman and Flash turned to see Hugo Strange standing before them.
"Strange!" Batman growled, "What are you doing here?"
"Mr. Thawne came and got me," Strange replied, "I admire his vision of the future, and this Anti-Monitor is most intriguing. Have you, by chance, met my associates? Dr. Destiny and the Psycho-Pirate. We'll be leaving with the Flash."
"Not if I have anything to say about it!" Batman said.
Dr. Destiny sprayed Batman with a chemical agent.
"That should take care of our caped friend for now," Strange said.
"Don't think you're getting rid of me that easily," Flash said.
"Oh no," Psycho Pirate said, "We have a special prescription for you, Flash!" He knocked him out with another hallucinogen.
Later, Earth 90 Flash woke up. He was on next to some sort of treadmill.
"Where am I?" he asked, groggily.
"WELCOME BACK TO EARTH 1, FLASH!" came a booming voice.
"Who are you?!" Flash called out.
"I AM CALLED THE ANTI-MONITOR!" came the reply, "MAR NOVU SENT YOU TO EARTH 14, BUT WE FOUND YOU! YOUR SPEED IS REQUIRED!"
"And if I refuse?" Barry asked.
"THEN THE MULTIVERSE WILL BE DESTROYED IN A PICOSECOND!" the Anti-Monitor replied.
Earth 90 Flash reluctantly got on the treadmill and started running, the anti-matter canon started activating.
MEANWHILE, ON EARTH 66, TERRY ARRIVED AT SELINA'S APARTMENT.
"Ms. Kyle," he whispered, "I need to speak with you."
"She's unavailable right now," Fish Mooney said, coming out from behind a curtain, "You'll have to deal with me instead."
"And who might you be?" Terry asked.
"My name is Fish Mooney," she said, coming closer to him and putting her hand around his cowl. "Ms. Kyle and I will rule this city."
"Mr. Powers might disagree with you there," Terry said.
"Well, he's not here," Fish said.
"I need to speak with Ms. Kyle about her daughter," Terry said.
"Well, you'll just have to wait, bat-boy," Fish said. She smashed a vase over his head, knocking him out. "I could have fun with him later."
"What have you done?" Selina asked, coming out to see the unconscious body of Terry in the bat-suit.
"Don't worry," Fish said, "We're one step closer to getting what we want now." The Monitor suddenly appeared. He engulfed Terry in cosmic energy and sent him away.
"The anti-matter canon has been activated," the Monitor said, "It's imperative we get to Earth 99 right away."
"We're not going anywhere," Fish said.
"What?" the Monitor asked, "But the multiverse—"
"…Will be just fine," Fish said, "We're taking orders from you or anyone else. This city will be ours."
"Then you have doomed yourselves." The Monitor said,
Back on Earth 14, Reverse Flash had comprised his newly assembled Legion of Doom, comprising of the Riddler, the Scarecrow, and Victor Zsasz.
"What's our next move?" Scarecrow asked.
"Well," Eobard said, "First, we must—"
"I am red as blood, and bring only devastation. Once I enter your world, it ceases to exist. What am I?" Riddler asked, interrupting him.
"Ed, this is no time for riddles!" Thawne replied, as they pointed out the window. He turned around to see the sky had turned bright red, crackling with electricity.
"What do we do now?" Zsasz asked.
"We can't do anything more, Nimbus," Thawne said.
"I'm sorry?" Zsasz asked.
"Sorry, Zsasz," Thawne said, having confused him with his Earth 1 doppelganger, Kyle Nimbus aka the Mist, "Crisis is upon us."
Meanwhile, at Police Headquarters, Jim and Harvey had captured Dr. Destiny and Psycho-Pirate.
"This yahoo keeps repeating the same thing," Harvey said.
"Worlds will live, worlds will die," Psycho-Pirate said, "And the universe will never be the same!"
"Harvey, look outside!" Jim said, as they stared at the red skies.
"Holy Mother—" Harvey said, "Guess the religious fanatics were right! Gotham has truly gone to Hell!"
Psycho-Pirate opened a breach and both he and Dr. Destiny escaped.
"Hey!" Harvey shouted, "Where'd they go?" Suddenly, Penguin burst through the door.
"Jim!" Penguin shouted, "First, that speedster takes Ed, now the skies are red and the world is ending. What's going on?"
"I don't know, Oswald," Jim said, "I think we just have to brace for the end."
Other worlds were wiped out by the red wave, including Earth 5, where Batman, Superman, Wonder Woman, Aquaman, Cyborg and Shazam looked up in shock at the red skies, and then on Earth 25, where Batman and Catwoman had just defeated Scarecrow.
"I'm glad you decided not to fully retire," Selina said, "But at least you've got that Robin guy to help you, the cop who helped us stop Bane and Talia." They looked up and saw the red skies and were immediately wiped out.
Back on Earth 66, Terry was flying through the skies in the Batmobile.
"Looks like the Batcomputer was right, Dick, the anti-matter wave is gonna hit our world in 20 minutes." Terry said, "I guess it's pointless to continue looking for Inque and Catrina now."
"Bruce would want you to continue the fight to the bitter end," Dick said, "I'm gonna go take Ace for another walk. I have faith you'll stop it, Terry." Later, as he was the walking the faithful Bat-hound, the anti-matter wave washed over the city.
"Holy Crimson skies of Death!" Dick exclaimed, as he looked up at the sky, embracing his impending doom. He was thankful that Bruce had since gone on to eternity and didn't have to witness this.
