A/N: So, the final battle will be split into two chapters, this one and the next.

BARRY

"We need to push them harder," Barry said as he stood in the center of a room, keeping his hands behind his back as he stood tall, in front of him, Strange, Wong, and Mordo, the members that Kamar Taj's council comprised of, sat in chairs. "Dormammu and his Zealots could be invading at any moment, even right now. They need to be prepared every second of every day for when he comes."

"We can't just 'speed up' the training process, Barry," Strange tried to reason. "Learning everything we've learned, mastering the basics, it takes time."

"Time that we might not have," Barry argued back. "These trainees, these sorcerers, they may or may not be ready but it won't matter when Dormammu starts bleeding the Dark Dimension here."

Behind Barry, Matt leaned against the wall as he listened in to the conversation. Barry eyed the council as he awaited their response.

"You're certain you've extracted as much information from Kaecilius?" Wong asked. "While you were under his cover?"

"As much as I could," Barry replied. "He mentioned a sort of machine but he never specified anything."

"And can we trust your word?" Mordo inquired as Wong and Strange glanced at him with surprise.

Barry tilted his head. "You mean you don't trust me now? When I was the one who went out there and undercover…for all of you?"

"The Dark Dimension may have corrupted you for all we know," Mordo claimed. "Is there truly proof that it hasn't? After all, you did live amongst the Zealots."

"Yeah, I did," Barry cut off. "I lived with Zealots, I ate with, trained with them, I…I fell in love with one of them."

Barry looked down as he could already see the looks of surprise and shock on the trio's faces.

"Her name is Jaina," Barry continued. "She's-"

"Kaecilius' daughter," Wong stated as Barry looked up and faced the trio. "You fell in love with the daughter of Dormammu's most trusted Zealot."

"I did," Barry admitted. "And she's carrying my child…a daughter. Mine and hers."

"You even impregnated her," Mordo said with half-disgust. "What you've done is-"

"There are a thousand words that could describe what I've done," Barry interrupted. "It doesn't matter. Not right now. While we stand around here, debating what I've done, Dormammu is out there preparing to kill trillions."

"Our world can hold a defense against Dormammu," Mordo claimed confidently.

Barry glanced at him. "Just yours? Have you ever been to another Earth?"

"No," Mordo admitted. "But I've been majorly responsible for training and teaching the trainees what they have learned. Helping them - making them master what they've learned."

"Yeah, you did," Barry scoffed. "And yet, your best trainee lost 2-0 against a super soldier with a bouncing, large, metal frisbee. Clearly you weren't very good at your job."

Mordo angrily stood up from his seat. "You would dare to insult me?!"

Barry growled. "The single most smartest you've said in this entire conversation."

"Both of you enough!" Strange yelled, his voice overtaking the conversation as everyone else remained silent. "Look, we'll keep training everyone and when the time for Dormammu comes, we'll do the best we can. That's all we can do no matter how much we keep arguing,"

That was how the meeting eventually came to an end as everyone dispersed. Barry and Mordo shot each other a glare before Barry left the room, Matt walking beside him.

"You alright?" Matt asked. "You know what? Don't tell me, I think I've got my answer."

Barry leaned against a wall, his arms crossed as he looked at Matt. "Yeah, and what is it?"

"You're going through a lot," Matt claimed. "You're worried that the woman you love and your unborn daughter are out there…and there's nothing wrong with that."

Barry shook his head as he bit his lip. "I should've brought her here…even if I had to force her. Maybe she'd hate me for it, maybe she'd never look at me again but she'd be safe. Her and the baby. They'd be here, they'd be alive-"

"And they still are, Barry," Matt said firmly. "You once told me to have faith and I'm trying. Right now, maybe you should try to."

Barry ran his hands through his hair as he deeply sighed. "I told her I loved her…after I broke her heart and turned against her." He scoffed humorlessly. "How stupid is that? I betrayed the woman I loved, shattered her whole world and that was when I chose to tell her I love her."

"We'll find her," Matt promised. "One way or another. We're going to find her. Whether it's before or after all this is over-"

Suddenly, Matt paused as he tilted his head away from Barry, his eyebrows crunching. It took a few seconds of silence before Barry turned to look at Matt, seeing the look on his face. He knew that look.

"What is it?" Barry asked. "What're you hearing? Talk to me."

"There's some commotion outside," Matt said as he and Barry walked to the outside of Kamar Taj.

Barry suddenly stopped as he saw it. Several sorcerers and the Avengers surrounded a pregnant woman, one who appeared to have been experiencing contractions, ready to give birth at any moment. He recognized her voice as she groaned in pain, her long, thin, chocolate-brown hair. Barry instantly rushed into the crowd until he was finally in front of Jaina, helping her stand. It felt different seeing her in her current state, her pregnancy had nearly reached the end of its course. By the end of tonight, Barry and Jaina's daughter, Lily, would've been born. Only, Barry was still worried if either of them would make it out alive. The pair locked eyes as Jaina cupped Barry's cheek before throwing herself at him as they hugged, Barry wrapped his arms around her as he kissed her brow.

"I'm sorry," Jaina whispered as Barry could hear her sniffing. "I'm so sorry."

"It's alright," Barry said immediately as the two pulled away from the hug and held her shoulders. "Come on, we have to get you inside."

Everyone had eventually headed inside as Barry helped Jaina to a room where she could lay down, Bruce had followed them to the room, having been a doctor, him and Strange could potentially have helped.

"She's already nine months through?" Bruce questioned.

"The baby has my speed," Barry explained as Jaina groaned. "Pregnancy only lasted four and a half months, everything else with the baby should be normal."

"These people can help her," Strange said as he and a couple sorcerers entered the room. "They'll take care of her. Barry, you need to see this."

Barry turned to Jaina as he held her hand and stroked her cheek. "I'll be back. You and the baby will be safe, I promise."

Jaina nodded. "Just…just come back to me."

He kissed her briefly before he nodded his head as she nodded back.

Barry, Matt, and Strange went to the outside of Kamar Taj as they met up with the rest of the Avengers and tens of sorcerers who also happened to be outside as well. He looked up to the sky in horror as he saw what he had been fearing for the past four and a half months. The sky appeared to have tears through it as if it were being ripped open across multiple areas, behind the tears there were realms of dark purple, purple energy with hints of green throughout it. The Dark Dimension. Barry thought.

"It's happening," Barry said. "Dormammu's bleeding the Dark Dimension into the multiverse…and he's starting with this Earth."

A few minutes later, Barry found himself, the Avengers, Strange, Wong, and Mordo in front of the grand staircase and behind the main doors inside the London sanctum. While carrying Morgan, Tony used his suit, which he had laid on the ground, to project a blue hologram that showed a three-dimensional view of New York City.

"I broke through one of S.H.I.E.L.D.'s old satellites and checked their security systems," Tony explained. "It was able to detect Dark Dimension activity all over the world, wherever it was bleeding into our world. However, I find something a little more interesting."

"What?" Wanda asked.

"A radioactive, Dark Dimension heat signature," Tony explained. "Right here, in New York. And, kiddos, if you look closely…"

Tony used one hand to zoom in to the map of New York City as the map zoomed in on the coast. The now-zoomed-in map revealed a large, canon-looking machine. Almost the size of an entire city block, the colored heat signatures revealed spikes of radiation and Dark Dimension energy coursing through it as orange, yellow, and red colors glistened over it.

"That's what's causing all this?" Barry asked.

"Yep," Tony deadpanned. "And the longer it happens, the faster this whole process speeds up."

"If the Dark Dimension bleeds in our world long enough," Strange warned. "and if it reaches the end of its stage within the machine…"

"Then what?" Natasha asked.

"What happens then?" Steve added.

"It'll set off an explosion," Wong stated. "One powerful enough to wipe out the entire multiverse in one go and then…Dormammu will replace the infinite space the multiverse once took with his Dark Dimension…a realm beyond life, death, and time itself, beyond the spatial coordinates of the multiverse."

"How long do we have?" Matt asked.

"No way of knowing for sure," Tony explained with a sigh. "The rates are speeding up inconsistently, there's no way of knowing for sure. At the most, if we're lucky, we have an hour."

"Terrific." Sam commented, dryly and sarcastically at that.

"Look, guys," Tony said. "I'd be out there if I could but with Morgan, I…"

"Hey, Tony," Barry said slowly as he put a hand on his friend's shoulder. "It's okay, I understand. We all do. You've done enough, really. Now be with your daughter."

Tony nodded as he patted Barry's shoulder. "You're a good man, Allen…and keep yourself alive out there. I'm not the only one who's got a kid waiting for me."

Barry nodded back. "Take Morgan and get to Kamar Taj, stay with Jaina and the sorcerers there. Keep yourselves away from the fighting."

Barry turned around and faced the rest of the Avengers.

"Everyone else," Barry said confidently and loudly. "Gear up. Now's the time. We go out there, we make our stand, and we stop whatever the hell Dormammu and his servants have for us."

"What makes you think we can?" Rhodey asked.

"Allen, we don't know who this guy's fought," Frank pointed out. "We don't even know what he's fought."

"I don't give a fuck who or what he's fought," Barry spat. "I don't care if he's fought demons or the devil. What I do know if he hasn't fought us. Not us together, not us together. We go out there, we stand and we fight and we make him fall…he's not invincible, he's not unbeatable. I can beat him. We can beat him. You have two choices…you give up on this fight before it's even begun…or you stay and fight so that we all get to see another day. So that the new world we're so desperate to find gets to see one. The choice is yours. Fight or don't. Either way, I'm fighting. Even if I have to do it alone."

Refusing to wait for an answer, Barry turned his back as he walked out of the main room, heading up to the higher levels of the sanctum as he went for the roof.

Barry stood at the very edge of the roof where thousands of Sorcerers and the Avengers stood behind him. At the very top ledge of the roof stood Barry, Strange, Wong, and Mordo. Barry stood in the middle, dressing in fairly normal clothing: sneakers, black jeans, and a black t-shirt. He had a sheathed sword that hung on his shoulders and rested on his back. A sword he had taken from the main sanctum. It appeared to be normal but Barry had learned that the sword was capable of absorbing energy and outputting it into single-strike, powerful blasts. The entirety of New York City had appeared to be a destroyed, apocalyptic wasteland. Even from the Sanctum, Barry could see the Dark Dimension canon as it blasted energy from the ground to the atmosphere, speeding up the process of the Dimension bleeding into the multiverse.

The clouds became dark as thunder roared, lightning flashed through the cloudy atmosphere as rain poured heavily. The storm only added to the fear of the sorcerers along with the Dark Dimension, as Barry could see, it even added to the intensity of the situation. Much like everyone alongside him, Barry could see the thousands of Zealots and Hydra agents as well as hundreds of runners standing by the canon. The runners appeared to have been remotely mind-controlled with special devices on their heads. Thawne. Barry realized. Him, Ward, and Hydra had been working with Dormammu for whatever sick, twisted reason. Barry didn't know if he could manage it but he would do his best to take care of Thawne, the runners, and even the canon if he had to. As for the Zealots and Hydra agents, the Sorcerers and the Avengers would have to manage them on their own.

Barry turned around to face the Avengers and the sorcerers as he pointed to the canon before raising his voice loudly. "See that? That's the weapon of destruction. This whole world, this universe, the entire multiverse…it dies at the hands of the Dark Dimension."

"There's nothing we can do!" one sorcerer cried.

"Yes there is!" Barry roared as they all went silent, the only sounds that could be heard for a brief moment were the pouring rain and the occasional roar of thunder until he spoke again. "What we can do, what we will do is go out there, stand our ground and fight…I'm not asking all of you to fight for me, for my team, for the universe, or for the multiverse. I'm not asking you to fight for fame, glory, or wealth…you won't get any. I'm asking you if you're going to fight for yourselves…it's your lives that're at risk, your friends that'll die right next to you if you let yourself cower away. Now I know that it seems like there's no chance, but there is. If you go out there, you stand your ground, you tell yourselves that…you are the shield that defends this world, and nothing can stop you."

Barry could see the sorcerers nodding their heads as he looked down to his fellow teammates, glancing at them. Wanda giving him a nod, Matt and Natasha holding hands, Sam, Rhodey, Steve, Logan, Frank, Thor, and Hulk standing beside each other. Barry nodded his head as the skies darkened, the freezing cold rain pouring harder, thunder booming as lightning flashed across the sky.

"There's an army of psychopaths, murderers, and runners out there," Barry said as he pointed to where Thawne, Hydra, the Zealots, the runners stood a quarter mile away. "Make them fall!"

A wave of roaring and cheering followed Barry's words as the sorcerers opened several portals with their sling rings, the portals taking them to the center of the battlefield where the runners, Zealots, and Hydra agents met them. The thousands of sorcerers went through before the Avengers followed, one by one the portals closed as Barry unsheathed his sword, throwing away the sheath. Sword in his right hand, he ran through the final portal, into the battlefield, before the portal closed behind him.

Everything that followed was a blur of movement, even with his own enhanced reaction time and senses, Barry couldn't think about the fight. All he could do was react. His body charged with orange lightning as he cut through thousands of Hydra agents and Zealots, slicing some in the stomach, cutting off their limbs, even killing a few of them. The runners charged towards Barry as he charged back his trail of orange lightning directly cutting through their clumps of red lightning. Barry kept his body moving, dodging avoiding hits from the runners, barely dodging scratches and bites. Barry swung his sword over and over as he cut through many of the runners, his adrenaline kept him going, his endless stamina keeping him from tiring whatsoever. The adrenaline built up in his body as Barry grabbed one runner on the shoulder with his left hand before using his right to plunge his sword through the runner's chest as he looked up to the sky and let out a roar through the storm.

Time passed as Barry cut the head off the last runner in the battlefield, he held the hilt of his bloodied sword with his right hand as he turned and saw twenty Zealots charging towards him. In the next half-second, Mjolnir flew through the air as it collided with the Zealots, knocking them away, killing a few. Mjolnir flew to Barry's left, returning from the direction it came as Barry looked to the origin. Barry and Thor stood close, both of them being drenched in the pouring, heavy rain as the storm continued to roar with lightning and thunder. Their weapons had blood that the rainy water washed away to the best of its ability.

Thor patted Barry's left shoulder as he yelled to him, trying to speak through the sounds of battle that surrounded them. "The battle goes on, my friend…you are a true leader!"

Barry nodded in response, his gratitude and respect to Thor. "We need to find the machine and stop this!"

Suddenly, a ringing sound echoed in Barry's head as time slowed to a complete halt. The rain froze in the air, drops of mud froze a few feet off the ground, everyone and everything around Barry was frozen, the lightning in the clouds remained still and unmoving. Without having orange lightning course his body, Barry had managed to move so fast that he perceived everything around within attoseconds. Every attosecond that passed in the real world, Barry could make it last over a minute. Within 'Flashtime', the term Barry had for this level of speed, Barry ran at super speed through the crowds as he reached the machine, a canon-looking one that was the size of an entire city block as the energy it blasted into the sky had been frozen still in time along with everything else, even the many pocket, tear-portals to the Dark Dimension in the sky. Barry looked at the very heart and center of the canon as he could see the main energy in it in complete still motion. Barry sighed in horror as the realization struck nearly as hard as the lightning bolt that gave him his powers. The explosion had gone off.

"No." Barry whispered.

"Oh yes, Barry," Thawne's voice brutally shivered down his spine as Barry turned around and saw Thawne standing a few feet away from him. "Oh yes. The bomb's gone off."

"Thawne…" Barry growled.

"As always, Flash," Thawne chuckled menacingly. "You're too late."

A/N: Yes, I am introducing Flashtime as one of Barry's abilities in this series. No, I will not be repeatedly using it for him and that will be explained in the next chapter. Also, like in canon, Barry can move at his real-time super speed within Flashtime, I'll explain that in the next chapter.

If it hasn't clicked in it, I am doing something similar to 4x15 of The Flash, only it's going to be consistent and not stupid. The next chapter should conclude this fight and the battle.
