Battle for the Multiverse

"Well, this is it. This is the very ending of the very end. I was leading the charge for the Grand Alliance and all our fellow allies that're being unified against the Coalition of the Red Star and the Empire of Darkness. That could be one of the largest conflicts in history after surviving unending bouts of radiation. I hope this is gonna be it"

--Su Ji-Hoon, The Final Battle

"The Coalition of the Red Star wins by making us think we're alone. But we're not alone. Good people will fight if we lead them."

--Poe Dameron, to the Grand Alliance

The Battle for the Multiverse was the decisive final battle for the fate of Earth and the entire multiverse, fought among the Grand Alliance and their fellow allies united against the Coalition of the Red Star and the Empire of Darkness. The monumental scale of the battle makes it one of the largest conflicts in history.

It will be happened in during the final World War III that the Grand Alliance will defeat the enemies (this means that this battle will mark the official ending of the Great Interdimensional War).

Prelude
Initially giving into fear and exiling himself on Ahch-To, Alexander Pepper was motivated by the spirit of his mentor, Romulus Augustus, who encouraged him to face his fear. Pepper then traveled along a safe route to Exegol in a stolen Xi-class light shuttle, using a Sith wayfinder found on the ruins of the Death Star II and transmitted his plotted course to the Alliance, allowing them to travel along his passage. Through information acquired from D-O, a droid that had been owned by a Sith cultist, Ochi, the Alliance learned that the Sith armada required a signal from a navigation tower in order to deploy off of Exegol, and devised a battle strategy to take out the tower. Poe Dameron and Finn, who had become the leading generals of the Alliance after Leia Organa's death, sent General Lando Calrissian and Chewbacca on the Millennium Falcon to Alliance-aligned systems to try and recruit any of the free worlds to aid them. However, Lord Commander Reginar Albrecht arrived on Exegol on his Mega-class Star Dreadnought, the Lord Trethium's Wrath, which served as the Immortal Armada's command ship.

Meanwhile, back on Exegol, believing his foes defeated, Supreme Leader Victor Nevarez vowed to take great pleasure in using the Dark Empire's Sith fleet to conquer the multiverse as revenge against the Grand Alliance for interfering in his plans. Victor then mustered the full might of his army, composed of the Sinestro Corps, the Black Lantern Corps, the Red Lantern Corps, Decepticons, Nobodies, Heartless, Parademons, Xenomorphs, Terminators, Sith Troopers, Combine Soldiers, Battle Droids, Mordor Orcs, Gundabad Orcs, Easterlings, Uruk-hai, Chitauri, Sakaarans, Outriders, Chitauri Gorillas, and Leviathans, to the surface of Exegol.

Villains from other universes are summoned into the battleground, this includes the Trix, the Dazzlings, the Koopalings, the Knights of Ren, the Death Eaters, the Real Organization XIII, the Black Order, Lord Drakkon, Steppenwolf, Bane, Lex Luthor (in his battle armor), Deathstroke, Black Manta, Shinnok, Shao Kahn, Sindel, Mileena, Shang Tsung, Quan Chi, Voldemort, Saruon, Smaug, Witch King of Angmar, Azog, Bolg, Syndrome, Tai Lung, Lord Shen, Kai, Pitch Black, Valtor, Diaspro, Chimera, Jadeite, Steele, Mojo Jojo, Princess Morbucks, HIM, Sedusa, Bowser, Ganondorf, Grogar, Lord Tirek, Storm King, King Sombra, Queen Chrysalis, Quintessa, Sentinel Prime, Megatron, Starscream, and King Ghidorah; who lets out an alpha call that summons even more villains.

In spite of overwhelming odds, Su Ji-Hoon managed to rise to defiantly stand against the Supreme Leader's massive army, when he suddenly received a message over his communications from Falcon.

Shortly after, Sling Ring portals created by Doctor Strange and the Masters of the Mystic Arts began to open up behind them, revealing the allies of the Grand Alliance: the Future Alliance, the Sonic Alliance, the Buttertoast Alliance, the Coalition of the Red Phoenix, the Beleninsk Pact, the New Central Powers, the Sweet Allies, the White Lantern Corps, the Green Lantern Corps, the Blue Lantern Corps, the Power Rangers, the Alfea Fairies, the Homeworld Gems, the Shirai Ryu, the Lin Kuei, the Rohirrim, the Iskandar Army, the Fiore Army, the Rune Knights, the armies of Gondor and Narnia, the Dora Milaje and the Wakandan tribes, and the Masters of the Mystic Arts from all around the Earth, as well as Amazons, Atlanteans, Asgardians, and Ravagers.

Iron Man, Captain America and Thor join the fight along with Black Panther, Shuri, Okoye, Falcon, Doctor Strange, Drax, Mantis, Star-Lord, Gamora, Spider-Man, Winter Soldier, Groot, Scarlet Witch, Vision, Quicksliver, Heimdall, Volstagg, Fandral, Hogu, Wong, Wasp, Pepper Potts (donning a blue-and-silver armor), Nebula, M'Baku, Valkyrie, Lady Sif, Korg, Miek, Howard the Duck, Kraglin Obfonteri, Ant-Man, Professor Hulk, War Machine, and Rocket.

Heroes from other universes join the battle as well, such as the Fantastic Four, the X-Men, the X-Force, the Defenders, the Watchmen, the Justice League, the Teen Titans, the Suicide Squad, the Incredibles and Supers, the Furious Five, the Powerpuff Girls, the Crystal Gems, Winx Club, Team Miraculous, United Heroez, Big Hero 6, the Pretty Cures, the Sailor Scouts, the Sailor Starlights, the Tokyo Mew Mews, the Ultra Guardians, the Cardcaptors, the Mysticons, the Star Guardians, the Maverick Hunters, Tuxedo Mask, Fujin, Nightwolf, Liu Kang (as a Fire God), Kung Lao, Kotal Kahn, Kitana, Jade, Sheeva, Baraka, Blade, Lobo, Kick-Ass, Hit-Girl, Supergirl, Hellboy, Punisher, Ghost Rider, Venom, Spawn, Silver Surfer, Duke Nukem, Master Chief, Bayonetta, Jeanne, Felicia, Ryu, Ken, Chun-Li, Cammy, Po, Master Shifu, Godzilla (resurrected), Mothra, Rodan, Kong, and even allies from other dimensions: Alita (from Alita: Battle Angel), Iron Giant (from The Iron Giant), Doom Slayer (from Doom Eternal), Kratos (from God of War), the Guardian (from The Terminator), and Dante & Trish (from Devil May Cry).

As their armies marched forward, their aircraft flying overhead and their leaders prepared, the war cries let out by them could be heard across the land, perhaps even the world itself as the fate of the entire multiverse hanged in the balance. Su Ji-Hoon stood firm and proud as his friends rallied next to him as he glared at his adversary. Nevarez's glare came back in full force as he and his allies realized that the real fight was just beginning.

As the heroes took their places, their powers, weapons and forces ready, with the sergeant calling Mjølnir back to his hand, Su Ji-Hoon then said five simple words, that spoke many volumes.


 *  "HEROES OF THE MULTIVERSE! Together." 

With that said, Thor yells a thunderous battle cry, as does Black Panther with Godzilla and Kong roaring in unison and the heroes charge forward. Victor, not wanting to be undermined by all of this, simply growled and held his Darksaber up towards the enemy, signalling his villainous forces to charge towards their foes before he joined along with them. The heroes continued to charge as they began what was perhaps their last battle, before they clashed with their enemies to a head in a massive assault.

Engaging the Armies
A violent battle immediately began between the Alliance, their allies and Nevarez's army. Both sides collided with each other on the ground and in the air, as a giant Ant-Man punched Smaug down to the ground. Iron Man and Pepper Potts fought together in the air, as Su Ji-Hoon and Thor traded Mjølnir and Stormbreaker as they fought off Sith Troopers.

Iron Man was ambushed by Cull Obsidian, but he was saved as Spider-Man grabbed the Black Order member with his web and caused him to fall, with the giant Ant-Man sending him flying by kicking him away. Spider-Man checked on his mentor and attempted to put him to speed on what happened after he woke up from a 20-year cryogenic freeze, but Iron Man quietly interrupts Spider-Man by hugging him, much to his surprise and returns the hug.

Air battle

 * "Welcome to Exgeol!"
 * --Poe Dameron

Later, an aerial strike team led by Dameron arrived on Exegol to find the Immortal Armada. They realized the fleet had the potential to conquer any world in the multiverse, since every starship in that fleet housed a military complement capable of annihilating any installation. Poe and Finn opted to launch a ground assault over an air assault in order to disable the navigation tower while at the same time avoiding being tracked. However, an officer spotted the assault force and informed Albrecht, who immediately recognized the threat and had the signal transferred to the Wrath, intending to lead the fleet out themselves.

When the lander realized the signal had been transferred, Finn reached out with the Force to identify the new source of the command signal. Identifying the Wrath as the source because it stood out among the Sith Star Destroyers, they carried forward with their ground assault and landed on the hull of the Mega Star Destroyer instead. Albrecht ordered a large group of Combine Elites and Sith Troopers onto the hull to stop the boarders, along with an electromagnetic pulse to disable their speeders. To his disbelief, another officer told him that they weren't using speeders; instead, they were using orbak mounts. The strike team managed to disable the tower after a brutal battle. Albrecht was not concerned, and simply ordered it to be restarted. As the Allied strike team prepared to leave, Finn and Jannah stayed behind to stop them from resetting and switching the signal to another Star Destroyer. Poe then ordered the starfighter pilots to launch an attack on the Sith Star Destroyers until Calrissian and reinforcements arrived.

Destruction of the Deathshead

 * "F.R.I.D.A.Y., what are they firing at?"
 * "Something just entered the upper atmosphere!"
 * --Tony Stark and F.R.I.D.A.Y.

Back on the surface, when Victor is quickly overpowered by Scarlet Witch, he orders the crew of the Deathshead to rain fire upon the battlefield. Corvus Glaive protests, pointing out that their own troops will suffer in the bombardment, but Nevarez, on the verge of being overwhelmed, orders the attack regardless. They comply and the Deathshead starts to fire all of its weapons onto the battlefield, and Scarlet Witch is blown aside, ending her her face-to-face melee with Victor. As the lasers fall, the Masters of the Mystic Arts summon Tao Mandalas to protect their allies from the bombardment.

As Spider-Man is being greatly outnumbered by Outriders, he is saved by Su Ji-Hoon throwing him Mjølnir to hang on to, he is then grabbed by Pepper Potts in her Iron Man armor, who then throws him onto Aragorn, who is being ridden by Valkyrie.

The villains laugh in joy as the heroes are suppressed by the airstrike, but every weapon suddenly stops firing at them and aims at the sky instead. Confused, Iron Man is told by F.R.I.D.A.Y. that something suddenly entered the atmosphere. It is then that Captain Marvel arrives from above, which the heroes are relieved while the villains are shocked, and single-handedly destroys the Deathshead, ending the airstrike while a bewildered Nevarez looks on not long before sensing Pepper through the Force, he retreats back to the Sith Citadel.

Iron Man then meets up with Doctor Strange and asks if this is the outcome they win. Doctor Strange answers that if he tells him, it won't be.

Showdown with the Dark Emperor

 * "Long have I waited...For my new heir to come. I never wanted you dead. I wanted you here... Emperor Zuskelgar II."'
 * --Victor Nevarez, welcoming Alexander Pepper

While the battle raged outside, Pepper entered the Sith Citadel and found Victor; who was possessed by Dark Emperor Torvivum Zuskelgar, in the throne room, which contained an arena filled with Sith loyalists. Nevarez expressed his satisfaction at finally seeing his nemesis, while telling him that the Alliance's strike team was walking into a trap. Above the throne of the Sith, he opened the ceiling, revealing an outnumbered and outmatched aerial strike team and its seemingly imminent failure against the Sith armada. Victor exploited Pepper's feelings for the Alliance, telling him that the only way to save them would be for him to strike him down in anger, calling him "Emperor Zuskelgar II" and encouraging him to take his rightful place on the throne of the Sith. This would ensure the Sith Lord's essence's transferal to Pepper's body, renewing the Coalition for the reign of a new Dark Empire. Pepper was faced with a confrontation of wills as the desire to save the Alliance as well as his uneasiness of turning to the dark side collided in his mind. With the Sith loyalists chanting, Nevarez prepared to be killed by Pepper.

However, a glimpse of hope came when Pepper sensed that Ruby Ramirez has arrived on Exegol. Landing her hijacked Lambda-class T-4a shuttle next to the Xi-class light shuttle, which Pepper had used to reach Exegol from Ahch-To, Ramirez made her way into the Sith Citadel. Ramirez somehow contacted Pepper through the Force and nodded. Pretending to strike down Victor, Pepper instead used the Force to transfer his own lightsaber to Ramirez as he ignited the lightsaber of Romulus Augustus in defiance of the Dark Lord, forcing the Rhyme Bunch and a cohort of Dark Thunder Guards armed with Tesseract-powered rifles to attempt to take down Pepper. Ramirez later arrived at Trethium's lair and reunited with Pepper, who had just finished the attackers off.

At first, Victor intended to kill both of them, but realized that Pepper is a God of the Force; something he had not seen for generations. Noting that their powers combined would allow him to fully evolve to his true form and finally ascend to godhood, Nevarez used the Force to drain the life energy of Pepper's and Ramirez's. As triumphant thoughts invaded his mind as he harnessed the power of both the dark side and all the Sith who preceded him, Victor pulled more life energy from them as if he was flowing from a river of light so only he, the one true Dark Emperor, would be restored. Drained of their powers, Pepper and Ramirez collapsed to the floor.

The multiversal fleet arrives

 * "My friends.... I’m sorry, I thought we had a shot. But there’s just too many of them."
 * "But there are more of us, Poe. There are more of us"
 * --Poe Dameron and Lando Calrissan

Up above, the Alliance was taking heavy losses, as Finn and Dameron continued to lead the fight. Temmin Wexley was shot down by Sith TIE fighters, making Poe realize that they were losing the battle. However, Calrissian arrived in the Millennium Falcon, bringing with him the Free Worlds Fleet, a massive armada comprised of over 16,000 ships from all points across the multiverse. The heroes are delighted to see that the inhabitants of the multiverse had come to aid the Alliance in their hour of need. Poe ordered the fleet to target the weakspots, to considerable effect. Albrecht was stupefied at the appearance and size of the fleet, arguing that the Alliance had no navy. Admiral Firmus Piett, on the other hand, realized that it was not a navy but just people that had finally had enough of their tyranny and banded together to bring them down. Sith Star Destroyers began falling to cruisers and fighters alike, with one being brought down single-handedly by a lone Y-wing piloted by Zorii Bliss, who had escaped the destruction of Yavin 4 along with her crew.

End of the Sith

 * "YOU ARE NOTHING! A FRENCH BOY IS NO MATCH FOR THE POWER OF THE DARK SIDE!! I AM THE LORD OF ALL VILLAINS!!!"
 * "And I... *calling back Romulus Augustus' lightsaber* ...am the Lord of All Good Guys."
 * --Victor Nevarez and Alexander Pepper, shortly before the former's final defeat

Exclaiming revenge for his first defeat at the hands of the Kids Club, Nevarez used the Force to pick up Ramirez, scornfully telling her that she would fall as the last Preschool Girl and threw her into a nearby abyss to an apparent death. Victor, having been fully evolved to his true form, told the Immortal Armada to not fear the feeble attack of the Allied fleet as no one will stop the Dark Empire's return. He then proceeded to ignite a powerful display of red-colored Force lightning into the air, which disabled or destroyed most of, if not all Allied starships up to the size of Venator II-class Star Destroyers, including those of Finn, Poe, and the multiversal fleet, and sending them plummeting towards the ground, along with the USS George W. Bush, the Earth Defense Fleet and even the legendary Tantive IV (which gets obliterated, killing everyone onboard). Much to Poe's shock, he realized he was losing control of his X-wing. Weakened and seemingly defeated, Pepper heard the voices of past Jedi, including his predecessor Romulus Augustus, Luke Skywalker, Luke's father Anakin, Leia Organa, Obi-Wan Kenobi, Yoda, Qui-Gon Jinn, Ahsoka Tano, Mace Windu, Luminara Unduli, Aayla Secura, Kanan Jarrus, and Adi Gallia encouraging him and lending him the strength to carry on against the new Dark Emperor.

Pepper then stood up, with his new courage received from the Jedi before him and the reformed Kids Club appearing behind Pepper to fight alongside him. Nevarez, noticing this, ceased his Force lightning attack on the Allied fleet as he gathered the members of the Legion of Evil. Poe, having realized that his starship's systems were back online, regrouped the allied forces and resumed their assault on the Sith fleet, stating that they had one chance to take out the armada of Sith Star Destroyers. Telling Pepper that his death will be the Alliance's final word, the Supreme Leader pulls out his Darksaber and ignites it before the two sides engage in a fight, Trethium eventually gains the upper hand soon after, resulting in Victor successfully striking Pepper with lightning which slammed him against a large rock and caused him to momentarily lose consciousness.

Laughing contemptuously at his opponent, Nevarez taunted Pepper with the fact that the Jedi were all but extinct. Suddenly, Pepper quickly recovered and responded with a Force push that sent Victor flying back to the throne. Pepper asserted that Nevarez's reign of terror was over, and Victor attempted to flee. Pepper then hindered his way and ignited his own lightsaber, challenging that Nevarez had no need to leave if he was as powerful as he proclaimed he was. Realizing he would have to fight the Jedi Master blade-to-blade, Victor called his Darksaber back, ignites it, and snarled that Pepper could not stop him because he became even more powerful than Pepper and his friends. In response, Pepper stated that his faith in the Sith and in the dark side itself made him completely arrogant. With nothing left to be said, both fighters engaged in a final duel before the Darksaber is knocked off Nevarez's hand, leading to Victor and Pepper struggling for control over the infamous lightsaber that once belonged to Tarre Vizsla, causing the crystal inside of it to shear apart, unleashing a wave of energy that tore the lightsaber in half before consuming the arena in a flash of brilliant, blinding light. Angered over the loss of the Darksaber, Nevarez unleashed a barrage of Force lighting at Pepper in a fit of rage.

Pepper then attempted to block the Supreme Leader's electric attack with his own lightsaber, but Victor mocked Pepper that he was "no match for the power of" the dark side and that he is the "Lord of All Villains." However, Pepper retaliated by telling Nevarez that he is the "Lord of All Good Guys," calling back the Augustus lightsaber and igniting it, using the two lightsabers in tandem to deflect Victor's lightning back at him. Unable to tolerate the strain of the immense energy reflected back at him, Nevarez screamed in agony and horror as he was disintegrated under his own energy. In a massive explosion that decimated the entire citadel, Victor himself, and all of the Sect of Eternal Darkness gathered inside, Darth Trethium—the man who wrought evil throughout the multiverse for decades—was ultimately destroyed along with Zuskelgar's spirit that possessed him, aborting the Dark Empire's return and permanently ending the ancient Sith-Jedi conflict once and for all.

However, the sheer amount of power required to utterly destroy Nevarez caused Pepper to faint; an event felt by Finn. Ramirez had somehow survived the earlier ordeal with Trethium, and climbed up the cliff from the abyss, running back to Pepper as she realized he was weakened after vanquishing the Supreme Leader. Finding Pepper completely tired, Ramirez and Pepper shared a hug as Jean-Marie Dupont arrived to rescue his former commanding officer.

Fall of the Immortal Armada
With the Supreme Leader's lightning attacks ended thanks to Pepper, the Alliance and the rest of the multiversal fleet continued to press the attack against the remaining forces of the Coalition. Meanwhile, Finn and Jannah took control over the turbolaser cannons on the command ship and fired them at the bridge of the Wrath, killing Albrecht and destroying the tower. The Wrath began to explode and descended towards the ground of Exegol with Finn and Jannah still on board, but they were rescued by Calrissian and Chewbacca onboard the Falcon.

With the Wrath destroyed before it could transfer the signal to another friendly ship, the entire Sith armada was trapped on Exegol. The Alliance and the multiversal fleet destroyed the rest of the Sith Star Destroyers in a similar fashion to the Wrath, by blowing up their weakspots. With the Dark Empire defeated and all the ships falling to the ground in ruins, Pepper, the Alliance, their allies and the multiversal fleet emerged victorious and left Exegol to return to Earth, where they celebrated the end of World War III.

Aftermath
As the Alliance and their armies left Exegol, they learned that across the multiverse, people were rising up as the weakened Coalition began to collapse without the Sith armada to reinforce them. Across the multiverse, where the Coalition had deployed Star Destroyers to distant worlds to try to force them into submission or destroy them, people rose up and destroyed the Star Destroyers. The heroes and their allies returned to the Alliance's headquarters on Earth, where they celebrated their victory, among them Pepper, Ramirez, Su Ji-Hoon, Finn, and Dameron.

The end of the battle saw the ushering of peace across the multiverse. Through Pepper and Ramirez, the ancient conflict between the Sith and Jedi finally ended in a Jedi victory as the deaths of the last two Sith Lords as well as the collapse of the Dark Empire marked the end of the threat of any Sith rule across the multiverse. Through Finn, Poe, Lando, and the rest of the multiversal fleet, the entire Sith armada collapsed on Exegol, with no threat of return. Their actions also ushered in a new sense of hope and courage across the multiverse as people gathered the will to rise up and destroy the last remnants of the Coalition.
