This is a part of "The tales between worlds: Into the multiverses and beyond" project, the most ambitious crossover ever. This fiction was made with my experience at Fanfiction prior, my times with crossovers works and various fictions, my time at Fire Studios (by Julius Raymore/Fire King who wrongfully betrayed me from Discord) and various roleplaying in Discord, as well as learning from various crossovers in general. Thank you for all your support, now we can start.

By the way, spoilers from included and/or represented works abound. Please read this fiction carefully.

The omniverse. Yeah. The totality beyond all multiverses. Home to infinite possibilities, if you will. Let's face it - it's everything that can potentially be if given the possibility: all of reality, across all alternate dimensions, planes of existence, parallel universes, possible universes, timelines, alternate continuities, realities, and multiverses within said totality. In short, it is EVERYTHING. Literally. The omniverse contains a transfinite - as in an infinite levels, hierarchies and infinity of (infinite) infinities - number of outverses. Thus, the outerverse is but a shard, a facet of the omniverse, and an extradimensional zone consisting of transcendent hyperverses, each of which is a complex set of multiple multiverses. A multiverse is made of space-time continuums consisting of, well... countless universes at least three dimensions each. Our universe is what the real life took the form of. (Note: our universe may have been created by the Big Bang)

Tommy Westphall have dreamed of everything. Pretty much the entire omniverse itself. All by himself, apparently. Then there's Zero Point (Fortnite), which brought us upon the island we ended up being able to play with through gaming systems in real life. Zero Point, in fact, was considered by gods outside to be the transcendental representative of the omniverse itself, as it's ominously tied to it. After all, the omniverse is the connection of the various and infinite realities connected together by the Zero Point. Different worlds have shown to be accessible via The Zero Point, as well as many other forms of inter-dimensional travel.

One day, a mysterious girl, between late-teen and young adult, with white short hair with long gradient ponytail dyed with a colorful pastel rainbow gradient, and multicolored eyes with full heterochromia, appeared.

"Zero Point, huh?" The mysterious girl stuttered.

The mysterious girl looked around, and saw everything that's happening nearby. As it turns out, she's currently in the main Reality Tree, in the Reality Falls, north of Greasy Grove,west ofTilted Towers; and South ofRave Cave. The girl proceeded to scans and analyze the whole thing.

Only for her to be overflowed with every single informations of what happened in the Reality Zero ever since the moment the Sideway Rift is formed. Including when the nexus orb that is Zero Point itself appeared inside the vault.

However, she seemed fine in the end, even after quickly absorbing all the details. Every. Single. Things. Happened. So. Far. In. Fortnite since the rocket launch. All grasped by the mysterious girl herself.

"I see..." *giggles*

Then the girl wanted to steal the power of Zero Point for herself, and so she pierced the log itself with her bare fist. Her fist easily and deeply dug down the log, but...

"Hey, you!" A participant in Battle Royale caught the mysterious girl. "Who're you, and what are you doing!?"

The girl then stared at the participant with her eyes.

"You cannot grasp my true power." The girl said. "Call me Zero."

"Zero?" The participant is confused. "What Zero?"

"That Zero... I bought from the Nonary Games." The girl replied.

"Nonary Games?" The participant realized. "You mean Zero of 'Zero Escape'?"

"How did you know?" The girl asked back.

The participant explained: "I've watched some playthrough of that series. I watched the whole trilogy of games, so I know a decent amount of what it is. The name 'Zero' in that case refers to the host of each life-or-death game... in-game."

"Hmmm... You're pretty knowledgeable, mortal shithead." The girl smirked.

"Wait what?" The participant shocked about the girl's words. "Hey, girl! Watch your mouth!"

The girl then pulls her hand off the hole created in the log, and then quickly sped up. Time for her became dilated to the point by the time the participant reached to the gun, not only she managed to approach the participant, but it's directly right next to the participant. She stopped speed there, and...

"Ahhh!!!" The participant is scared after seeing the girl speeding up. "Wh-wh-who're you!?"

"Sandevistan sure work wonders." The girl, by the alias of Zero, candidly exclaimed. "The customization done serves me and my array of godly powers really well."

Then the Zero chokes the participant, much to the latter's horror.

"You're trying to say 'You... you monster!' like typical muggles would do?" Zero the girl said. "Very well..."

Then she blows the participant's head up with activation from her hand, eliminating the participant in the battle royale.

"Maybe you could escape from a Nonary Game, but could you all escape from the nightmare made by me?" Zero the girl then laughed.

Then she returned to where she came out of: in the log she struck, Reality Tree. She then put her hand into the hole, and realized that the energy from Zero Point is leaking from it.

"How about... burning the whole thing?" Zero the girl then ignited the energy by casting flames from her hand stuck in there, burning it all out.

And this set the log aflame, to slowly spread into the roots and the rest of Reality Tree itself. At this point, a crack in the sky was formed, creating a Sideways Rift, which two certain mecha-like creatures emerged from: one red-and-black-clad with almost samurai-like armor, and one blazing in blue and covered by spiky golden chains.

"Found you!" One of the creatures then released a golden chain towards Zero the girl. The chain then quickly hurled towards the girl.

Only for the girl to jump and then catch the chain mid-air.

"How!?" The one with golden chains is shocked at the catching.

Zero the girl then yanked the golden chain without hesitation. This not only hurts the said creature, but also pulled that creature into the other creature, causing both to collide, hurt and crash-falling down. The Zero landed gracefully.

"Too bad, Byaku Shin." The Zero mocked the creature. "I'm far more powerful than any of you can ever be. Even in dreams."

The creatures then stands up clumsily.

"Look at those crybabies, those currently in battle royale!" Zero the girl shouted. "Kyuju Kyu and its surrogate proto-form is like two fuckably real shit here!"

This annoyed the hell out of the remaining participant in the Battle Royale at the moment. They're all confused as fuck after hearing the Zero. Meanwhile, Kyuju Kyu and Byaku Shin recovered and are pissed off at the girl who just shouted.

"Your impuny arrogance disgraces the Song of Rifts itself." Byaku Shin responded. "Come, the Byakuya!"

A large army of Byakuyas then emerged from the Sideways Rift, just in time before it closes. The army falls down, scaring all battle royale participants nearby.

"That's a piece of cake already." The girl then activated Sandevistan. "I want a while cake and have to eat it too!"

As time dilates around her, even the fast-approaching Byakuyas ended up appearing to have slowed to a crawl. Then Zero went to dance around and applied some of her powers, and striking many Byakuyas consecutively. Then she went for a Mantis Blade (equipped on her right arm), which turned into Margueritte Bois de Justice that manifests as a scythe like extension on her right arm. She slashed all the remaining of the Byakuya army, ending with decapitation of all of them.

By the time the Sandevistan deactivates, no more than a dozen of seconds has passed, but the entire, hundreds-strong Byakuya army has been destroyed in front of Kyuju Kyu and Byaku Shin.

"How... can... this... be...?" Kyuju Kyu in fear of what just happened.

"Remember, Kyuju Kyu, Byaku Shin," Zero the girl noted both. "You cannot grasp my true power. And my powers that I can and have demonstrated only compound that fact."

In utter disbelief and horror, the battle royale participants ran away together as fast as they possibly could. But the Zero then pointed her finger upwards, the lightning struck a few participants running, eliminating them on their spot.

"Call Agent Jones!" A participant while running away.

"I can hear you all." The Zero reveals.

At this point, the Reality Tree just started to be engulfed in flames, but it also, started cracking, violently messing up with the reality around it.

"This isn't good!" Byaku Shin told Kyuju Kyu. "We have to sing the Song of Rifts!"

"The Song of Rifts cannot even save any of you now." The Zero then evilly laughed.

"That cyberpsychotic god..." Kyuju Kyu then looked at Byaku Shin. "Use Centipex and Dimension Fusion Charges, and unite with me!"

"There doesn't seems to be any other way to extinguish those flames right there." Byaku Shin exclaimed. "Let's do it, the 'its'!"

"Don't be sarcastic, proto-sis!" Kyuju Kyu responded.

"None of that would work!" Zero the girl then stay away from both.

A couple of hours later, Agent Jones arrived at the scene. Reality Falls is now crumbling, as the Reality Tree is now engulfed in flames, even in its roots. All the roots cracked as well, wreaking havoc every reality around each of it.

"No... That can't be..." Jonesy watching the Reality Tree burning in horror.

Then Jonesy noticed both Kyuju Kyu and Byaku Shin.

"You're... Agent Jones from the so-called... Reality Zero?" Byaku Shin noticed. "The Legend of the Seven?"

"Yeah, it's me, Jonesy!" Jonesy greeted both. "Nice to meet ya, but we have to save the reality!"

"We're trying to!" Kyuju Kyu responded. "Please notify as many people from as many worlds as you all can!"

"Ok, but what's going on!?" Jonesy asked back.

"Mister," Byaku Shin replied. "I and Kyuju Kyu found out that a girl self-named Zero appeared and set that tree aflame."

"Reality Tree? Oh god..." Jonesy shocked. "No wonder why the reality is going haywire seemingly by itself just now."

"There's not much time left to explain here." Kyuju Kyu told Jonesy. "Kyuju Kyu and Byaku Shin, products of Embryo 101."

"The Hundred-Gods." Byaku Shin continued the brief introduction.

At the time, Jones is currently livestreaming his own perspective and point of view to some certain worlds as well as all of Fortnite Battle Royale to see. Needless to say, controversies and fears sparked wherever the livestream is shown publicly.

"We must save the reality." Jonesy commented.

Then suddenly, the Zero appeared right in front.

"Uh oh, The Seven just escaped." Zero is disappointed that The Seven has escaped. "But I found you, Jones."

"Who are you!?" Jones angrily asked.

"You cannot grasp my true power." Zero then proceeded to rip of Jones' heart.

"Ugh!" Jonesy violently moaned as his heart is out.

"You may be immortal, Agent Jones, but I can simply kick you out of the existence." Zero then crushes Jones' heart.

Jonesy falls down, unconscious. Zero then formed a cannon from her left hand, and shot him in the head.

"Headshot!" Zero shoots out. "Overkill for an ordinary muggle, but just right for that immortal jackass."

"NO!!!!!" Kyuju Kyu screamed at Jonesy's otherwise-impossible death.

"99, I'm full!" Byaku Shin notified Kyuju Kyu! "Let's combine!"

"Agent Jones is... dead...!" Kyuju Kyu is in "tears". "But it's ok, you're full. Let's combine, proto-sis!"

"And then what?" Zero preparing to leave. "Don't you know that wouldn't even affect the chaos even a bit, after I set this particular tree in fire?"

Some of Jonesy's friends (no, not The Seven) arrived at Seven's behest. They were horrified to see Jones' bloodied corpse lying alongside where the Zero is standing.

"No!!! You killed him!" A friend screamed, wanting to avenge.

"You cannot grasp my true power." Zero the girl responded. "Also, that jerkass shouldn't be able to oppose me again."

"Who're you!?" Another friend asked.

"You're already dead." The Zero then used her Mantis Blade turned-MBdJ to swiftly decapitate them all.

Some participants later decided to try and fight back so they went back. But then, the Zero casually slaughtered them all in her way. Meanwhile, Kyuju Kyu and Byaku Shin unify themselves to become one again, with all 101 original parts installed as well.

"The Song of Rifts..." The united creature stood. "... commence."

"Singing the Song of Rifts?" Zero heard the creature. "Nah, it doesn't matter. It won't save themselves or the Zero Point."

Zero then uses Sandevistan. It turns out that because of Zero's powers, the Sandevistan allows her to travel between worlds as well.

"Bye, the Looped Island." Zero bid farewell to the island. "Serve you right with Zero Point served." *evil laugh*

Zero escaped, while the Reality Tree ultimately explodes. At that exact same moment, the Song of Rifts is sung. The blasting energies collided with each other, crashing the reality itself. Pretty much all the participants caught in the crossroad were annihilated. The Zero Point is then destroyed because it's overwhelmed both blasts of energy overloading even its potential black hole together before it could possibly implode altogether.

The results? Extradimensional cracks appeared literally everywhere in the entire omniverse, even though not all of them is alway so accessible. The whole thing ultimately lay wastes to the very island where Zero Point once resided.

Both Kyuju Kyu and Byaku Shin disappeared. Few levels of infinite amount of lives lost. The livestream ended in the horror of all that saw the whole things explode. The Seven ended up hiding in the dark.

Among the watchers was the Hegemonies: the Hegemony Gods (of Shinza) and their fellows.

"What the fuck!?" Hajun shocked at the livestream.

"Another world in ruins now." Mercurius after watching the livestream.

"What's... just... happened?" Ren Fuji trembles after the ending of the livestream.
