Chapter 1- Battle Over

Dark Multiverse

Earth(-1)

Apokolips

Thunder echoed as the sky was darkened. But it wasn't your run of the mill night sky, no, it was a bloody red sky, gushing through the earth's atmosphere as waves of ferocious winds powered by velocity reaching at high speeds as the man stronger than a locomotive himself: Superman and the god of lightning himself: Thor, race side by side at an extravagant group of Parademons and distinguished Chitauri Aliens.

Thor bellows a war cry as he flies with Stormbreaker in his hand, blue mesmerizing lightning circling around his chainmail suit along side his cape and muscles as his eyes fire up with lightning, his hands tightened around the shaft of his mystical axe. He raises Stormbreaker and summons a ray of lightning and shoots it directly at the disturbing scaly grey aliens, blowing them to bits until all that's left is their purple gulps, intestines all scattered across the battle field with their blood oozing into the seams of the ground on planet Apokolips, some of their heads ripped clean off their lifeless bodies and thrown across the field.

Meanwhile, The man of Steel is hovering in the air while the Parademons who are scattered in the air are forming a huge formation in front of him with their alien advanced energy rifles in hands, aiming at Clark ready to shoot with content. Unfortunately for the Apokolipian Aliens, Clark is faster and narrows his eyes, feeling his heat vision starting to kick in. When it does, Clark bellows as he fires his heat vision, enlighten red rays aiming at every single Parademon in sight, burning right through their skulls, their brain guts flying out of their heads and falling to the ground, making a disgusting smooshing sound as they do.

But Clark's not done. He clenches his fists, with a face of determination, and that's when he flies straight at them with his fist in front of him, tons of strength built up in him. As he gets closer and closer, Clark yells before finally reaching them. He begins to throw violent, deadly and strong punches at the Parademons, breaking every single bone in their body, crushing their heads together, sending blood and guts all over Clark's face who was weirdly...satisfied.

But those aren't the only heroes who have joined the battle field. Along side Clark and Thor joined, The man out of time; Captain America, the Bat of the future; Batman, The Scarlet Speedster; The Flash, and the genius billionaire playboy; Iron man. Who are also joined by; The Scarlet Witch, Wonder Woman, Green Lantern, Aquaman, Green Arrow, Black Canary, Spider-man, Hulk, Falcon, War Machine, Black Widow, Hawkeye, Cyborg, Vision, Martian Manhunter, Supergirl, White Canary, The Atom, Nightwing, Redhood, and Antman.

They are all were doing their own damage across the war zone; Diana slices half of a Chitauri's face off with her sword, Barry phasing his hands through Parademons and Chitauri's chest, crushing their guts from the inside, getting a mix of purple and green blood plastered on his hand, Clint and Oliver shooting multiple arrows back to back, impaling them right between their eyes or sometimes in the balls-mostly Clint, Hal using his will green lantern ring and conjure a shit amount of Willpower to create multiple green constructs such as a big ass anvil, trains, and even a fucking bear trap that he used in the air to impale multiple Chitauri and Parademons out of the air and get stabbed repeatedly by the bear trap, soon enough, bits and pieces of both Chitauri and Parademons were splattered on Green Lantern. In short terms it was absolute chaos.

But then came the final blow.

Lightning and Thunder stuck down on Apokolips as the Kryptonian connects his fists on the Apokoliptian God's jaw; Darkseid.

Darksied growls as he's taking back by Superman's strength. Clearly, he underestimated him and now look where that's gotten him; Kneeling on one knee, holding his jaw, defeated.

Darksied's invasion lasted for a week throughout the multiverse and it was up to the world's greatest heroes and earth's mightiest heroes to form together and take down the God. Darksied has been destroying planets with the help of his Parademons and no one was brave enough to face-that was until 5 years ago, where Barry Allen; The Flash made a mistake and rewrote the timeline, changing many events. After realizing what he's done he went back in time but only to come back where everything was different. There he discovered; there was a new team of heroes called the Avengers, Barry was apparently in a team called the Justice League with him being a founding member alongside with Oliver and Kara who seem like they been in the league since the beginning, And the horrifyingly one making it feel like his word ended. His girlfriend Iris was...dead.

He tried to renew everything, just fix all of it, but turns out there are consequences with Time Travel. He found out the hard way when his supposedly friend and leader of the JL; Batman confronted him about his antics and beat the living hell out of him until he spilled the beans. He reminds him of Oliver but turns out in this new timeline, Oliver wasn't even the shit no more. There was a new Vigilante. And it was the Dark Knight himself.

In defeat, Barry just decides to make way and try to live in this new timeline. At least he was still owner of the amazing and the future of science studies; Star Labs. On top of that, he still had his friends; Caitlin, Cisco and Harry. Luckily Barry also still had his job as a forensic at CCPD, where now Joe is the Captain of the force.

But just as Barry was starting to like this new timeline, The Justice League was called upon to a mission down at New York about a villain destroying the city that never sleeps known as Knull. Turns out the Justice League weren't the only ones who were called on this apocalypse.

The Avengers- a group of remarkable people that can fight the hard battles that no one ever could, was after Knull for months, trying to gain a way to take him down but they been having no luck. It was then the Justice League and Avengers soon met up and after a disagreement, a big conflict happened.

They fought.

It was a full out Civil war between The Justice league and The Avengers. It was never determined on who won but it didn't matter. They both had the same goals; to protect the people. That motto made them settled their differences and now the Avengers with the help of the Justice League, managed to take down Knull with a little bit of help from a man on a silver surfboard. And the crisis was averted.

Later, the Justice League and Avengers realized their ways are similar, causing them to befriend them.

Sure some were little iffy about it such as Tony and Clint since he was threatened by Oliver's looks and skills, which Barry found amusing.

Some of the Avengers really liked the Justice League so much that they even suggested that some move over to their earths. But their leader; Captain America says that it would be better for the world if all the Avengers were in the same world. But that gave Barry and Clark an idea.

After days of researching back on his earth, Barry and Clark managed to find a way to change the frequencies of those earths or in simple terms: found a way to merge earth-99 and earth-1, making it so the Avengers and Justice League were as one.

And as years went by, Barry, Oliver, Kara and even Caitlin found themselves some new loves with some of the Avengers as they did aswell. Oliver married Natasha, Kara married Pietro, Caitlin was having a child with Steve and Barry was married to a bright auburn haired girl who gets him a lot more than Iris: Wanda Maximoff.

Maybe this time line isn't so bad.

Or so he thought.

As Darkseid stands defeated, Diana reaches to her side and pulls out her shiny glowing lasso before throwing it over at Darksied's neck, tightened it around his throat.

"You will leave this earth now!" Clark demands as he stands over Darksied with fists clenched, glaringly intensely at him.

Steve steps forward and says, "You will not return to our world,"

"Say it!" Diana snarls, tightening her hold around the Apokolian god. "The lasso of truth compels you,"

Natasha who has her guns pointed to the back of Darksied's head says with a slightly intimidated tone, "I'd listen to her. You do not want to get on her bad side, I learned that the hard way,"

Clint notches an arrow and and loads it into his bow, aiming at Darksied. "Uh I think it would be easier for him to speak if Superman hadn't just broken his mouth," Clint mocks.

"Your seriously need to learn about dramatic threats, Hawkeye," Black Canary says, starting at Clint from behind.

"Touché," Clint simply says earning a shake of a head from his friend and similar archer: Oliver Queen.

Darksied growls before raising his armored hand to his neck and begins to tug on the lasso until finally, it let goes of him. "I will not return. I have no need. For the truth is..." he trails off, turning around, raising his hand and summoning a huge orange swirly portal that feels like the huge portion of it was made out of fire with blinding lights. He takes a step forward then turns his head half way as he grins. "I have what I came for." He cryptically says as he steps through the portal, disappearing as the portal closes moments after Darkseid walked through.

"Well that wasn't very ominous at all," Clint quips, slackening his arrow on a bow string.

Alright I know your gonna hate me for the short chapter but I need to get this book started and so one chapter will do. Hopefully I did good on explaining how the Avengers and Justice League teamed up, and with the fight scenes.

Don't worry I'm uploading my next when I finish with it. But hope you liked this opening.

Please leave reviews and let me know what you want to see in my book. Till next time.
