Spoilers from included and/or represented works abound. Please read this fiction carefully.
"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!"
"This could be used to empower both us and the falling fork." Vengenance Jones realized. "We're killing all the birds with a single stone!"
The alliance gets into a battle stance, as the teams rallies them together with one phrase...
"INFINITY!" Liu Kang starts off loud and clear... and "united." *quietly*
The moment the phrase is finished, the Crisis ones yell, and the full alliance gathered together, charge across the krossroads and field against the hordes of the corrupted Equation in a war scene presented by one big, glorious shot. The twisted army, in turn, raised their things with a grin forming on each's face as the Order beckons in return, as if they've finally got a war worthy of their time at last. That glorious shot of pretty much every single one left in existence running into battle, fighting for the fate of the continuum and beyond. So when two armies finally clash, mutual carnage follows.
Shinra and Ouma blasts Ultra Comics in a valiant attempt to beat the comic-man down. A Mjolnir fly right into a cluster of corrupted, sending a healthy dose of lightning to strike them out. The mechs strike some corrupted kaiju right at their face and knock some of them to the ground, albeit damaged in the process. The Ultras fired their beams onto the ground to knock entire army down. the Battle Buses, armed with arsenal across fiction, shot down some of the Gentry. The speedsters overwhelms the batches with their own speed, brutally so on both ways though. Elemental benders weaves to hinder the corrupted, aiding the Nazis in killing off infected Loopers as well. Cars are mounted with mana-fed miniguns, gatling down corrupted warriors. And against the forces of the corrupted Equation.
"You can't escape from crossing fate!" System is done fooling around. "Die." *headshots some brutes*
"Hey! I need something to heal in case somebody irrevocably wound me." Rachel Alucard asked for help. "Can you fulfill-"
System throws a bottle of Slurp Juice to the vamp, and did the laser pillars to mooks, brutally vaporizing them. The observation girl then did Fatalities to the remaining ones on the way. Rachel immediately took the Slurp, but is attacked by a corrupted Cull Obsidian.
"Calendula!"
Cue her Astral Finish (Clownish Calendula) on the Cull Obsidian and accompanying horde to death. However, Rachel is then headshotted by a corrupted sniper with Boom Sniper Rifle... *boom*
"Yu do not proceed!" An army of Dame Merciless (among the Gentry) held some gods hostage.
"No. Harbinger system won't allow it!" Lyla Michaels, the Harbinger system, objected. "Behold!"
"The Ultimate Drift! Nix Uotan! Superjudge!" The Superjudge himself arrived. ""Begone, the Gentry!"
The two blasted the Dame Merciless army away with the rift-charged blast and cosmic energy together.
Serial killers slaughtering mooks together as a sacrifice to help out the heroes. Meanwhile, Anakin Skywalker/Darth Vader flips some of the corrupted brute over like nothing, and... "DIE!"
There's Yosuke Hanamura, using his Persona Jiraiya, leaping onto an infected T-Rex back while the latter is holding X-Lord in Baller with its jaw, causing enough of a distraction for that Looper to leave the Baller and chucks a rocket launcher at the eye of the Rex, *rocket ammo explodes* and allowing the Persona to finish the beast off.
"Fire!" Gunners team up and surrounds together, firing their guns at every corruption on sight.
"Meep meep!" Road Runner outruns corrupted animals and left them on the crosshairs.
...Tom and Jerry use tanks to finish them.
"Momotaros!" Nick Fury called the red Taros for help. "Can you possess an actual god? I know you're not used to it, but..."
"Very well! Let's go!" Momotaros jumps to the scene, and taunted Telos, who was using the domes for military summons.
"You will pay for the end of my master and the damnation of all reality!" Telos pulls all the triggers in liquid metal, gatling the mooks. Then he slashes down a corrupted mutant, "Reality is ours!"
Momotaros to a leap of faith... jumping to the planet-machine. The eyes turns red.
-*points* "I have arrived!"/"俺、参上!" *spread arms*
"What the!?" Deimos is baffled.
"Arak!" Valda called out.
"From start to finish, I'm always at a climax!" Here comes M-Telos!
He summons Rider Monsters to distract and dispatch the corrupted, creating chaos. Momo actually learned of the true power of Telos, enhanced by Zero Point.
"An oni... possessing an entire planet!?" Son Goku is baffled.
M-Telos holding DenGasher in Sword Mode on shoulder, and in boisterous fit did Momo strike the Cube Queen.
"YOU!" The Cube Queen revulsed. "You don't fuck with the Last Reality!"
"The Order did." M-Telos conjures liquid metal.
In the meantime, reality is running out, as all of the existence gradually disintegrated by the corrupted wall, annihilating the way towards the Beach and the Islands. The rate is slowly decreasingly as it gets closer to the the point. At the same time, Nix Uotan and Lyla, fresh off destroying Dame Merciless, quickly returns to the Ultima Thule boat, and traversed out in the midst of the ongoing battle; the mechs covered for the boat while that leaves the Beach.
A few of Lord Broken laughed at the Loopers and tried to overwhelm, but is stalled by the Dark Knights.
"Thank you." Catalyst thanked them.
"Get. OUT!" The Drowned (-11!Bryce) yelled.
"Holy cow! Do you remember what those monstrous houses did to our realities..." Era jumped to the female Drift. "I must have passed out, because when I woke up and everyone's gone, but some other realities were there right? They told me all timelines are dying and we must stop the Order, and heroes there opened a massive rift alongside my colleagues-"
Catalyst hugged Era for relief. In return, both kissed each other like lesbians do. The Dark Knights didn't care, and instead have the Dragons of the Bat finish off Lord Broken.
Vergil the half-demon swordman dices up the corrupted soldiers, and spammed spectral swords on the fellow mooks. Slaughtering for sake of his family, he under the motivated guise destroys a brute with his own skill and finesse. Then he walked on another half-demon with a katana as well, with white hair to boot.
"You... the other me." That man tripped Vergil down, and then immediately combo'd.
"Urgh!" Vergil is knocked down, but quickly gets up.
"You are half-demon. You have white hair. You have Yamato. You seek power." The man was followed by his demon army. "Just like me. Look like cosmic circumstances have brought up together."
"Who are you?" Vergil called out.
"I'm Vergil, the fallen Nephilim. I fell because I'm not worth morality." The man introduced himself. "These are my demons. I lead them, and-"
"You're a half-angel? And you betrayed your own family!?" Vergil is baffled. "You look like you're a resentful, birthright-biased, traitorous weakling with my name in you!?"
"Correct!" No. 765 laughed. "He threw away all his remaining goodness except his looks. He betrayed a graffiti witch, resented his brother, and blamed his own mother for the latter. And viewed humanity as inferior-"
"Since everyone's busy, why don't I kill you!" DmC!Vergil attacked his original counterpart with killing intent. The demonic armies are assigned to kill No. 765.
In the Ultima Thule, Lyla notices infinites of worlds are being annihilated.
"Multi-trillions of multiverses are falling each milisecond! The existence is shrinking down!" Lyla reported.
"It's converging at Reality Zero." Nix Uotan strings through. "Well, let's go to the wall..."
The boat ripples to Hypertime, only to find it's being consumed by the wall.
"Everything's being wiped out!" Lyla changed the direction. "Get to the lost!"
The boat enters retconnian afterwards. However, they saw the wall creeping around and destroying even lost cosmos and realities as well.
"Nowhere is safe." Nix Uotan realized. "We're not even solving Mobius without stopping the Order. We must carry on!"
"Next destination: Reality Zero, the land. Zero."
The boat lands down at Helios, and the two hijacked the forecast towers with Rift Beacons to locate and attract the trail.
"NOOOOO!" The Cube Queen is stabbed by M-Telos.
"Arak! Take this!" Valda threw a Junk Rift attached with C4 and a piece of magic crystal to the possessed. "Go to the room!"
"Huh?" Darkseid noticed Telos.
"Thank you! So you upgraded a whole dimensional junk?" Momo catches the composite junk. "Let's go, go, go!"
Valda hold line with her omnipotence-supercharged sword of hers, while the planet-machine possessed ran with the junk. On the way was the corrupted Vtubers, and M-Telos swiftly overcame them with the power of DOMESDAY with Zero Point power! Arriving at the entrace, Momo is blocked by Omni-Godmodder and Argimed.
"It's over! Ideas will ragequit! The Order is the one left!" The Omni-Godmodder unleashed their nerd rage right on the avatar's face.
The two attempted to murder the planet-machine, only to be interrupted by the teams behind the base alliance gained before the recruits between the two and M-Telos.
"You. Tried. To. Ruin. EVERYTHING!" Riane loading herself with her Arbiter power, and she isn't going to let the Omni-Godmodder get away this time.
"Enough of you and that evil empress!" Kyoman Kusanagi (草薙 京万) yelled.
"I don't even know who some of you are." The Omni-Godmodder didn't know the K-children by the Zerobreaker.
"Why did it have to be you!?" Argimed is infuriated.
"You both will." System smirked.
This is followed by the mates let all their fury loose upon the two past CXA enemies, and a beatdown issued gradually bypassing each powers. The two were countered with appropriate powers, and then overwhelmed by the Sandevistan taken from the page.
"We're not even fooling around. Now begone!" Angela unleashed her E.G.O. right in front of the two, conjuring the power of the Library at point blank.
As it just so happened, Argimed barfed out a mass of neurons down the ground as the Equation in the monstrous briefly purged off. It was Carmen's with the Light, and turns out the clone duo has already added it as an ingredient through the monster's manipulation.
The rest of the mates are just stepping on the act, and with all just walking and brief dashing: no further rush, no charging in. Just casually marching over to both threats and leave them scrambling. And they're only concerned about saving reality and not that they're facing off against two beings who managed to almost bring the divine continuum down with minimal effort overall, as if "you are no threat to us" at go. Which is possible thanks to a really copious amount of teamwork and Cross All.
"We're... outclassed by a part of alliance..." Argimed is then tortured by the power of Seed of Light. Carmen's body was taken by System and now refitted with the neurals...
"What have you done!?" The restored Carmen immediately stabbed the two without even touching anything.
The glowing E.G.O drills skewered the threats in a manner that horrified Zerobreaker as she came to the scene. By that point, the beatdown bought Momo/Telos time to take the composite junk to safety and onto the room.
"You... FUCK YOU!" The former empress is fed up. "That's it! Mobius go!"
Zerobreaker teleported back to the room, but not before the teams notice the caster.
"You're not going to make it again." Jumpson quipped in all seriousness.
"Activate it now!" Zerobreaker yelled at the two. "We cannot delay it anymore! The CXA and co. are fighting back!"
"Oh dear, why? Shouldn't we make sure all opposition is lost?" The queen replied.
"Also, our troops!" Titan!Shang questioned.
"No time to waste! If they continue, we will be foiled and gone!" Zerobreaker warned both. "They've become too powerful, too coordinated, too determined, too creative and too personal!"
"What!? You're going to put our armies-" The queen is baffled.
"JUST DO IT!" Zerobreaker yelled out in desperation.
"Off we are!" M-Telos attacked the three from seemingly nowhere, having domed all the way to the floating room with the composite junk.
Suddenly, countless copies of Omni Super Saiyan Tengen Toppa Zero Point has appeared throughout multiverses, courtesy of Momo. These absorbed the omniversal influx of energies from Project Mobius, shielding all of existence from the breaking origin and preventing the wall from accelerating in its destructive way to Reality Zero. As the god-mechs destroyed, another spawned and spawned across where the wall hasn't reached yet. Which is represented by flashes of multicolored Chrome, gold and everything and nothing.
"Guys... I'm at the limits!" M-Telos got to do his best to channel half of the full capability into summoning the copies, and half to make sure the three doesn't get to kill him.
All the influx absorbed got splintered from each mechs' destruction took the form of a small meteor rain each, bombarding to either incapacitating armies or forcing them to take cover. Thankfully, the tendril leading to the Beach was secured by the dome which deflected the rain off.
"AAARGHHH!" An entire army of Intellectron is strcuk by the meteor rain, and exploded and fell down.
To be continued...
