Spoilers from included and/or represented works abound. Please read this fiction carefully.
"Ultra is the end." Ultra attempts to force the alliance into submission.
"Hold the line! Hold the line! Hold-" Cue Pulsefire Ezreal melts down. "...Theeee liiiiiiiiineee!"
"Disgusting!" The soldiers averted their sights.
"This is what the New Gentry is made for... no, made of!" The Anti-Life girl gloated. "What do we call this Equation?"
"Don't!" Reiji Arisu shouted.
"It doesn't matter. Nothing matters." Zero blasted the Father of Ultra, Ken. "Now, it's always over!"
"Father!" Ultraman Taro cried.
Father-Ultra crumbles down from the power of the Gentry. Infuriated and horrified, Taro immediately fired his Strium Beam, only for it to be deflected back by the Cube Queen, right to his Color Timer.
"ARRRRRGH!" Taro got mortally hit.
"Father!" His son, Ultraman Taiga witnessed that deflection. "NOOO!"
"Taro!" The rest of the Ultra Brothers are horrified.
"Defy us, and you all perish." Zero threatened the Ultras.
"What have you done!?" Ultraman Zero scathingly called out. "Oh, you have another of my name-"
"You're both too early and too late to stop us!" The Cube Queen countered before the Ultra is able to do his catchphrase.
Suddenly, the Beach quakes, and the horizon lit up in flames. The main Darkseid, who has already been automatically Gentrified as a result of the completion, has growled at the reaction.
"Gotcha." The voice trolled the Order.
"What?" Everyone are caught off.
"Hey, guys... do you read us or something? It's us. We have recruits." Another one called. "Can you hear us? On your back."
"Could this be..." Reiji noticed.
The gang and crew approached from a flame portal, alongside kombatants from all timelines, including fellow Titans. The alliance looked back on them at surprise. The giant ones also looked down in surprise.
"No." Damian barely reacted, still in disbelief of the glorious arrival.
System was the one calling, and she with the fierce-looking nod as everything gradually widens up.
The real versions of the earlier summoned Battle Pass guys landed around the members, triumphantly placing. Then came the Monitors from all of history, guided by Strange Supreme and Arrow's Nash Wells, the Pariah of that multiverse. Then all versions of the entire League of Extraordinary Gentlemen showed up, equipped with armories provided through OASIS.
"Everyone?" Travis noticed.
The entire OASIS, led by Wade Owen Watts "Parzival", gangs up against the Order... warcry: "Reality is ours!"
...and very soon the rest of the recruits came to the scene. From normies to superhumans and metahumans, creatures and monsters to eldritch creatures, cyborgs to robots, magicians and mages, sorcerers, fighters and hunters, aliens, wildlife (even extinct species), gods and angels and demons, all and all throughout space-time, basically all of the remaining existence against the omniversal Order. The empowered Shadow Demons also made their stand against the order, even holding metal signs saying "THE REAL VERSION OF YOUR FOUNDERS HATE YOU ALL, THAT ORDER OF THE PARIAH!" in various languages throughout reality. And not just the big names in any media, real or fictitious, are involved. Nor just there's the main timelines joining the fight.
"What?" The Anti-Life read the signs.
Yes, all of the remaining existence against the omniversal Order. The Crisis ones then leapt to the front of the entire alliance, making it clear they're opposing the Order itself. Then the remaining real-life armies arrived as a group, spanning across all of alternative histories (which at the time were being overridden by the Realitiers and the corrupted hordes) and possible futures (also at the time overridden), plucked out into here and armed with their weapons enhanced by fictions' powers for one last fight for the fate of the total continuum: all of history ended up uniting against the Order, even the goddamn Hitler! The fairy tales also showed up, landing in front of the corrupted and besides the alliance, with a furious expression in each character's face.
"Oh. My. Fic." Deadpool is flabbergasted.
Survivors of the rest of all mythos across all existence also arrived, with Greek!Kratos (who's the past self of Norse!Kratos, himself being part of the alliance before said self) on point. Alongside all these survivors joining the fight, are a... literal wishing star, who clearly notified all of them of the massive battle and obviously scanning the entire battlefield for the alliance.
"Absolute reference overload. One overwhelming army." Parzival uses his e-god status to aggravate the Order. "Cavalry at its logical extreme."
With all the recruits all willing to aid the alliance in fighting the Order, all emerging from gateways of light - rifts, portals, Cross Gates, you name it - like gods reawakened in all their splendor, all just to unite against eldritch destructor army, really made it look like a miracle just happened. And when the star floats down, who else is there to help? The Chronicler. That's right, the Omniverse overseer, who was never allowed to deal with the dead, only to record and move on, was forced to directly intervene because all of existence is in beyond-infinite danger, not just the trillions of multiverse he ever recorded, thanks to earlier Metron and now the recruits; now going up against an omniversal terrorist organization, going as far as to break his rules and aid the alliance.
As the alliance look in awe and relief, all versions of the Crime Syndicate lands, glaring their rage at the Order. Not even the mortally-inverted ones would tolerate the massively-omnicidal shit the Realitiers tried to cause. Cue the Titans the heroes look frightened and aroused, halfway in full surprise.
"Is that everyone?" Irene Adler asked.
"Y'all wanted more?" An ultra-advanced AI version of Nightmare Eclipse is baffled.
Then, the giants not previously used by CXA during Zerobreaker war made appearance as well. All of them. Yes, even Demonbane: Dead End leading infinite army of Elder God Demonbanes, each leading an infinite army of Demonbanes.
"You brought 621 and the Rubicon too!?" Deadpool lampshading Armored Core VI: Fires of Rubicon in shocked. "Infinite reference overload! Even the finale isn't complete until Demonbane helps us!"
"No... how could you?" Titan Shang tsung is shocked. "Our victory was complete! This can't be!"
"And why can't I erase you immediately!?" Ultra Comics is furious.
"How's this for an army, you omnicidal monsters?" AkaRed, real Tommy Oliver and the real Kamen Sentai Go-Rider (the heroics one, who recently took back their titles and powers from the evils) yelled, while leading all Kamen Riders, Super Sentai and Power Rangers.
From the look on the Order's faces, it's obvious that the terrorists absolutely hate the sight and sound of the force that has come to back CXA up, and within midnight, to boot. What's more, the arrival of the assembled... everything, completely back ups the rebooted girl's suspicions and throws the Order's statement about their omnicidal terrorism being the salvation to all reality right back to their collective ass as they all themselves witness to just how many realities and space-time their actions have negatively impacted; for all of them, it wasn't just personal, it's literally far eviller than thou (TV Trope intended). Now all the remaining survivors are here and they're all gunning for them and Project Mobius.
"Traitors and resistance a like... becoming gods yet again just to defy everything again..." The Zerobreaker is disgusted. "All gathered together in one place, all for one final damnation. The last Armageddon, where we'll win."
"Ragtag bunch of misfits stood before Crisis itself. An omniverse came together to stand by their side." Chronicler closes his Codex and pilots a B.R.U.T.E., empowering it with his powers. "That's the beauty of the most ambitious crossover ever, a meme from the real world that transcends fiction."
In response, the queen spitefully forced Titan!Shang into plucking the room out immediately and show its content to the alliance, which exposed the Mobius Chair to all. The Titan sorcerer obliged because he's fed up with Liu Kang at this point. The first thing she and he saw are the One Who Laughs and Pariah, and the Fire God respectively.
"You... not even you!" The queen is disgusted. "Founders, why would you side with the CXA!?"
"Liu Kang, you don't deserve to exist at all." Titan!Shang is disgusted. "Project Mobius is our only way. Because we're the final solution. You have no real place in continuum."
"There's nowhere to run, the Queen of Hearts." The man in black pulled a gun. "Nowhere to hide. With nothing to change."
"You made me and my beloved suffer in Borderland, taking over it as part of this Beach, with the adapted rules applied to already terrorist group." The woman in black called the queen out. "All that, on top of the Dark Multiverse of madness?"
"Your soldiers is why I lost my real life. My kingdom. And nearly my existence." The rebooted flips out the Order. "The son of thunder were right to betray you and leak your infos."
"This is the last reboot card ever. All of the rest has been erased by mass entropy." Telos then rebooted the Hegemonies and the rest of heist crew co. "Now, we have a fight against the omniversal terrorists."
"Oh... I'm back. My goodness!" Kado Thorne is back.
"Guys!" Nolan hugged the vampire, and Antonia hugged Shimmerdusk.
"We oppose our dark idea selves' messes, and that's coming from us, the worst of Crises!" Pariah called the Order out. "We want nothing to do with your omniversal terrorism so long it's not ours!"
-*cringes* "Exactly." The One Who Laughs laughed.
"We're here to destroy project Mobius and end the equation." LeBron James declared. "We have banded together to rid all reality of your terrorism."
"The NBA player is right. He was just playing basketball and doing his dad thing." Saya of Ouma disapproved. "You're petty enough to spite a famous athelte on terrorist way, and not even us Ouma would dare break all reality out of spite and evulz."
"The threat you pose to everything ends today." Liu Kang declared.
"Such certainty, Continuum Exploitation Authority." Titan!Shang dismissed. "That this war will end in your favor."
"It can end no other way." Riane refuted. "Because everything matters."
"Do they?" The queen dismissed.
Purple rifts surround the Order and opposite to the alliance, spawning every single remaining victims of the corrupted Equation, with the number count roughly rivaling the entire alliance.
"In this Crisis, nothing matters." Argimed, Omni-Godmodder and Zerobreaker used those rifts together, using the combined power of the Equation.
An interdimensional mesh of rifts groups all the corrupted on the Order's side, and pretty much all those have been Gentrified. The twisted army is formed, much to the two's pleasure.
"Behold, CXA, the literal Infinite Crisis we unleash upon you!" The queen declared, standing on the platform with modded Mobius Chair that used to be the whole room.
The twisted army shows up against the alliance with killing intent.
"This would've included me evilly, had you not saved me." Maho/Grey Sister told the CPUs/Goddesses and the rest of the Candidates.
The corrupted with a twisted smile, hisses. Similarly, the alliance - even those normally not so much been capable of direct combat normally - are all filled with determination.
"Everyone, this is it." Kronika called the alliance. "Gather with everyone we have. Your familes. Your accomplices. Your friends and foes. Fight alongside all of them. We go out together."
"Cross All." Meden Traore activated the energy. "That's right, everyone. We fight as one army."
"One Earth." Team Touchdown declared.
"One planet." The Titans the heroes declared.
"One galaxy!" Team Dai-Gurren declared.
"One universe." The Titans the Keepers declared.

"One Big Bang." The alliance then spoke that up to follow. "One Big Bang."
"One Big Bang." Said the alliance, one group by one. "One Big Bang."
"One Big Bang." Dr. Manhattan capped this off.
"Together." The teams declared.
"CXA welcomes you all." Ms. Continuum briefly bowed down. "And thank you, readers..."
"One Big Bang... meet Cross All... and it seems..." Titan!Kitana can feel it. "Crisis energy, anti-Crisis, meme energy, anti-meme, creation energy, destruction energy... I can feel all of it..."
"All our existence... Whether it be the urge to live in the moment, to make single, pivotal decisions that will live and kill worlds, or embrace all our history, all our stories..." Crisis-Prime too. "Everything good, bad, ugly and beautiful, all of it... we can feel it all... too."
"All truth in one go. All reality in one fell swoop. All besides us, not them." Valeria also feel as well. "More reason for me to search for knowledge of... everything."
"Yeah-hah!" Oscar the tiger roars. "We are feeling everything!"
To be concluded...
