F-28. The Multiverse Destroyer

Casino Castle

Bill Cipher saw from afar as towers crumbled and minions fell. The destruction was slowly making its way to their tower. "It can't…It can't end like this." Tears forced their way out of Bill's eyes. "Lord English will rewrite the universe…"

"So… even our devoted manager is giving up on us." Dimentio said. "I guess there's no point in playing around, anymore." He formed a Space Block over Bill and exploded it.

"AAAGH!" Bill was grounded, but seemed to sustain few injuries. "What?! You're betraying us, too?!"

Dimentio expanded his hand and grabbed Bill forcefully. "His Lordship should have known, Bill, when he promised us our very own dream worlds, the only thing that satisfies me is space. The sweet tranquility, the endless solitude, and as long as a shred of matter remained in the universe, I would not be satisfied. And why in the world would I want to live in a realm of HIS creation?!" Dimentio approached the unmoving lord. "The most atrocious artistry I've ever seen! He could not create a world of nothing even by leaving the canvas blank!"

"Ca…Caaa…"

Dimentio bent over his shock-ridden eyes. "Do you know why your ambitions fail? Do you know why your minions betray you? The reason is simple: it's because you are a terrible writer! You're a useless piece of matter who never had a chance, and your so-called friends saw you as just that! The only thing I can give you credit for is showing me the multiverse."

Dimentio made a Space Block over English and exploded him. He fell out of his chair, but suffered no other damage. "Ah, of course. THAT wouldn't kill you. Space doesn't beat Time. But given enough firepower, I'm sure that will change." He squeezed Bill and threw him across the room, then bombarded him with Starbursts. "You'd be surprised what a super-dimensional being can find after quick explorations of the multiverse. I found so many Fountains of Youth and immortality potions that I don't NEED Lord English's timebending to stay alive!"

"You ungrateful bastard! Just what do you plan to do?! When Lord English regains consciousness, he'll obliterate you!"

"I will not give him the chance, Mr. Cipher. For the past three years, I have been collecting life elixirs from the multiverse and making myself stronger. My body has adapted with the Multiverse Portal more and more! At long last, I am one with the multiverse!" His body began to brim a bright pink.

In all the universes, the Dimentios spoke and the portals whirred uncontrollably. "I have become the Sea of Worlds that links all dimensions together! I have outgrown all dimensions and can play with them like toys!" Inside his Logia dimension, universes surrounded him everywhere. It made the Noah's planet storage look insignificant. "And once I force these worlds to collide, the explosion will be fantastic! Neither Lord English, the IDA, nor ANY remaining universe will survive! At last, the realm of endless space will come to fruition! And I will make it happen IF IT KILLS ME!!" (Play "Terminal Velocity" from Sonic Colors!)

Act 7: The Grandfather Tower

A massive portal was beginning to form at the top of the highest tower. Nebula's group made it to the base of the tower just in time to see it. "Is that Dimentio's doing?!" Sunni exclaimed.

"I wouldn't doubt it." Nebula said. "That amount of Space Chi is enormous. Sunni, fly us up there!"

"You got it!" Sunni grabbed the group in psychic.

"Wait, I've got motion sickness—GAAAAAAHHH!" Emily cried as they went rocketing skyward.

They swiftly avoided green candles that shot the flames from left and right. Several windows opened on the tower and fired cannons, but only with Emily's Observation Haki could they tell which ones would open. Laser barriers activated, so Sunni used a Psychic Shield to get through them, but had to deactivate it whenever possible to conserve energy. Suddenly, a great wide barrier spread out from one part of the tower, and it had chi-blocks to keep them from teleporting past it. "We'll have to go up from inside!" Nebula shouted.

They flew into a window, and the inside was composed of giant gears. Sunni kept flying them up, with Emily using metalbending to move them aside. Giant skulls with Heartless Emblems came flying up after them, so Emily had to grab the gears and chuck them downward. The skulls were held back, and Sunni saw a steel hatch about to close on them. She boosted, but the hatch was close to closing, so Nebula shrunk their dimensions to get in the gap. They successfully made it, so Nebula resized them. The skulls could not get past the door, either.

The following part of the tower was divided into narrow passages, so Sunni made her group float in a line to get through them. One of those holes suddenly angled right, and when Sunni made the quick turn, they were back outside. A glass tunnel prevented them from roaming freely, and when they soared up, the tunnel spiraled around the front of a clock. A large Amp appeared and chased them through the tunnel, which spiraled around and toward the center. They picked up speed as Sunni kept a steady right turn, and they escaped through the center before the Amp caught up.

"We made it!" Sunni yelled, for the spiraling portal was even larger and mere feet away.

"I can see that!" Nebula replied.

"AHA HA HA HA! And so, my niece arrives like a cliché hero under the powers of deus ex machina! I hope you weren't relying on Jirachi to help you fight me. Your strength was weakened since your battle with Thanos, and even then, the only reason you won is because he wasn't from this world. But I am different! And even Jirachi's powers can do NOTHING to combat the MULTIVERSE!"

"S-S-So, how are you going to beat him, Nebula?" Emily shuddered.

"I can't."

"YOU CAN'T?!" the others screamed.

Well… not by myself. Nebula smirked. It's true, he's too powerful as he is now… but if Calliope's prediction comes true, THEY'LL arrive any second!

"So, you admit defeat…" Dimentio said calmly. "Aha ha ha ha… Well then, my dear niece… perhaps you will like to join me after all. Join your uncle in the endless serenity: the Eternal Space!"

"Gum-Gum GOOEY PISTOL!!" Monkey D. Luffy fell from the sky and PUNCHED Dimentio with the force of a meteor.

Dimentio regained balance and rubbed his sore jaw. "Well, that was a little rude. Tired of fighting the fodder, are you? Oh?" There was something sticky on his jaw: a light-purple goop.

"Hee hee hee!" Luffy snickered, for the purple goop was plastered over gloves on his fists.

"Dimensional Adhesive!" Stanford Pines presented to the members of the IDA. "I found this under my hometown on a buried alien saucer! It has the capability to seal dimensional rifts. This much alone won't be enough to stop the Thirteen Darknesses, but if we gathered vast quantities, we might have a chance of sealing the Multiverse Portal!"

"That adhesive must exist in other worlds, too. We must begin collecting it immediately." Zedekiah Strong replied.

"But how will we be able to amass enough? Dimentio has linked thousands of universes." Sir Reginald asked.

"We will have to analyze this being further. If he is the core of the Multiverse Portal, then he is the one we need to retain."

Dimentio looked behind his right when Ichigo appeared, his Zanpakutō covered in the adhesive. "You're an inter-dimensional being that can exist in multiple dimensions at once. Your body is a portal that allows the universes to leak into each other. If it wasn't for you, our worlds would've been safe!"

Natsu appeared and punched his flaming, goopy palm. "But on the bright side, we got to make a whole bunch of friends! And now we're all going to kick your ass!"

"Aha ha ha ha! I see… you're not all in my Logia space. You're back in your Original Worlds, talking to my physical forms. Well, go ahead. Lock up those portals. I have more than enough universes to create a Multiversal Explosion! Your worlds will NEVER be at peace! Your existence is-!"

Two Naruto clones punched Dimentio from both sides, fists covered with adhesive. "Then we'll just have to kill you a thousand times at once!"

"Aha ha ha ha! You and what army?"

"That one." Luffy said, picking his nose.

It was then Dimentio found himself surrounded. There was Allen Walker, Ruby Rose, the Original Aang, Avatar Korra, the Joestar Family, the Avengers, Wolverine, Akame, Edward Elric, Yato, Gon Freecss, Atsuko Kagari, and thousands of heroes surrounding him everywhere. Each of their weapons was drenched in Dimensional Adhesive. "There's no way you can handle us all!" Joseph Joestar declared.

"Every one of us prepared for this moment!" Ruby Rose twirled her scythe. "We're going to seal the Multiverse Portal from all openings, so you can NEVER terrorize us again!"

"Aha ha ha ha ha… the multiverse truly astonishes me… truly. Against forces you can't possibly comprehend… you push forward." (Play "The Ultimate Show" from Super Paper Mario!) "And yet… you are all so ugly. Cluttering my beautiful space. I will destroy every last one of you with the full extent of my power!" His body brimmed and the transformation commenced.

The points on his jester hat grew large and spiked, stars appeared under his eyes, and his striped cloak fluttered open, exposing the Sea of Worlds inside. He seemed to have six hands, with both sets merged in with each other. "The powers of the Multiverse are mine to command… With this, I have everything I need… to erase EVERYTHING!"

Boss fight: Multi-Dimentio

Luffy entered Gear 2 and bombarded Dimentio with Jet Gatling, the Zathurian enduring the first hits before opening portals to catch Luffy's fists and redirect them back at him. Dimentio compressed Luffy's stomach, but the pirate entered Gear Third and puffed himself back up, punching Dimentio with giant fists that the latter countered with his own. Ichigo leapt at him from behind and slashed the back of Dimentio's head. When the Zathurian opened a portal to drop Shooting Stars on Ichigo, Ruby Rose leapt up to his giant face for strikes with her goop-covered scythe.

Dimentio rose to the sky and opened portals above them all, stomping giants boots and fists inside, but Pit Icarus flew skyward and slashed the entity's eyes. Pit flew higher and rocketed down with enough force to bring Dimentio back down. Akame struck Dimentio with Murasame, but the poisonous sword had no effect due to his enhanced life force. Ryūko Matoi used her Scissor Blades to cut up Dimentio's cape, and feeling her, the Space God made Space Blocks appear and explode around her.

Yato sliced Dimentio's cloak portal with his Regalia, Yukine, but a hand reached out of the portal and pulled him in. Yato was thrown out in pieces, with portals over their cut parts, and Dimentio pummeled them all with Starbursts to keep them from reuniting. He could not focus further attacks as Sebastian Michaelis began to paint adhesive over Dimentio's hat. Dimentio willed the points of the hat to divide and attempt to push him off, but if Sebastian could not dodge such a simple attack, what kind of butler would he be?

"First comes Rock!" Gon Freecss declared, swiftly dodging Dimentio's Starbursts. "Rock! Paper! …GLUE!" He performed a great jump when Dimentio tried to ensnare him in a Space Block, smacking the adhesive over the entity's face. "Mayenab Dysheebudo!" Hearing a girl's voice, Dimentio about-faced to see Atsuko Kagari pouring adhesive into her Shiny Sprinkler. The device rapidly spun around, spraying the substance all over the living portal. Dimentio warped the sprinkler away, but Diana Cavendish was still able to drench him, levitating adhesive with magic.

Purple spider-webs latched over Dimentio's eyes, and before he knew it, ten different Spider-Men were swinging around and binding his dimensional bodies in Dimension Adhesive. Fortunately for him, this only applied to their respective portals, so Dimentio was able to smack them away by dividing his hands into eight. Captain America's Vibranium Shield then stuck itself in Dimentio's nasal bridge, followed by Iron Man's rocket punches to the mouth, during which Cap climbed up to retrieve his shield and stab Dimentio's eyes with it.

Dimentio sucked the Avengers into pocket dimensions and struck them with a storm of Space Lightning. It mattered little, for it was time for Kirito, Eren Yeager, and Meliodas to slice Dimentio's limbs with their powerful swords. Dimentio bent the swords' dimensions in their direction, slightly cutting the wielders, and then Mario and Link whacked him with a goop-covered hammer and sword. Kirby swooped in and laid the beatdown with his Ultra Sword.

Don't leave Rayman and Jak out of the mix, beating up Dimentio with pure martial arts. Then came Sly Cooper to slap goop on the deity with his cane, along with Ratchet and his trusty OmniWrench. "Fine, you outdated game characters! How about a little downgrade?!" With a burst of energy, Dimentio turned everything in his radius two-dimensional.

"Mama Mia! He's-a made us old-school!" 8-bit Mario exclaimed.

"I don't know how to move in only two directions!" Ratchet yelled.

"I do!" And with that, Rayman attacked Dimentio the good old-fashioned way, while Mario jumped up to his head and Link dealt the same sword maneuver on the feet. Sonic repeatedly bounced against his body, but alas, none of the sprites could dodge a giant meteor that launched from a portal in the background. Donkey Kong and Diddy Kong had been out of the meteor's range, so the duo rolled up as Diddy tossed his uncle onto the deity's head, laying some furious beatdowns with his goop-covered fists.

"Perhaps a little less data than THAT!" Dimentio reduced their dimensions one more, leaving everyone as one-dimensional lines. This was nothing to Mario and Kirby, who were already one-dimensional to begin with, so they attacked Dimentio, barely noticed by him at all as all lines looked the same. "You lesser life-forms are utterly irritating! Very well… I'll give your dimensions back and INCREASE MY OWN!" Everyone's 3-D shapes returned, and Dimentio began to multiply himself with five dimensions, six, and eight-

And then the Incredible Hulk smashed the easy target back together, with help from The Thing and Batman. Allen Walker and Ruby cut him to pieces, and Harry Potter and Oliver used magic to spread the adhesive around his body. "ORA ORA ORA ORA ORA ORA…!" Jotaro's Star Platinum laid rapid punches on Dimentio's front, and Luffy did Gum-Gum Gatling on the same side, with neither interfering with the other as they were in separate dimensions. Banjo and Kazooie also flew above Dimentio's head and performed a Bill Drill using the bird's goop-covered beak.

Dimentio warped all the pests away from him, then reduced their dimensions to tiny size. Jimmy Neutron used his size ray to make himself giant, and the Pines Twins used their magic flashlight to make themselves giant, attacking Dimentio with enlarged versions of the goop. The aggravated Space God shrunk them again, but by then, his original shrink wore off and everyone re-expanded. "He must be using almost every ounce of power to keep the universes connected!" Ichigo assumed. "He can't use any other powers to their fullest potential."

"You dare to doubt my unlimited power?! You sickening pieces of matter, I-"

Natsu socked Dimentio in the side of the head, and Thor brought his hammer powerfully down on his crown. "You can't even keep track of all of us." Natsu said simply. "Everyone's been attacking you since this battle started, but you only hit a few of us at a time. Heck, some of them probably closed their portals."

"Your petty attacks don't mean a thing to me. No amount of sealing you can do will ever stop me, and no amount of attacks will bring me pain!"

"I'm not so sure about that." A girl's voice said from nowhere. "Up here!" Dimentio rolled his eyes up and spotted Diwata Uno.

"Huh? Oh, right… you're the girl with the Moon Firstborn. …What was your purpose again?"

"Oh, calling me USELESS, are you?! Well, how's THIS for useless? I used moonbending to turn invisible and sneak up on you! And look what I brought with me!" Something materialized above her: it seemed to be a bloated moon with eyes and a mouth.

"WHAT THE HECK IS THAT?!"

"This guy is Crest, and he needs to lose some weight after that Last Lunch! But it won't be pee coming out: it'll be a juicy little liquid called MOON DRIP!" Diwata grabbed the Firstborn and SQUEEZED him like a sponge. Sacred blue liquid squirted into Dimentio's mouth. It had a juicy, fruity taste, yet it left an unsettling feeling in his body.

THUMP! Dimentio felt his heart beat painfully. "Ack! What did you do to me?! I swallowed entire Fountains of Youth, so many elixirs, so nothing you can do can possibly…"

"Moon Drip can cure supernatural ailments, silly. No matter what you drank from those other worlds, nothing beats the power of Firstborn Magic!"

"AAAAAAAHHHH!" The overwhelming powers of the multiverse were crushing in on him. "ACK! ! PAIN! THE PAIN! Why won't the multiverse listen to me?! I…I'M LOSING CONTROL!!"

"HE'S GOING TO BLOW!" Ichigo exclaimed. "Everyone, PATCH HIM UP!"

"You should've known!" Luffy readied his Elephant Gun. "Not to underestimate the power of OUR TEAMWORK!"

"Our SPIRIT!" Ichigo joined.

"Our WILL!" Naruto's clones climbed around Dimentio and slapped adhesive.

"Our EMOTIONS!" roared Natsu.

"Our HEARTS!" Mickey Mouse used the Keyblade to seal the portal in adhesive.

"Our STRAWBERRY MILK!" Bo-bobo entangled him in goopy nosehair.

"Our FREEDOM!" declared Captain America.

"Our DREAMS!" Akko Kagari cheered.

At the same time to deliver their final blows were Allen, Ruby Rose, Akame, Ryūko, Meliodas, Kirito, Mario, Link, Kirby, Fox McCloud, Jotaro doing the "ORA ORA" thing, Ratchet, Spyro, Alibaba Saluja, Danny Phantom, Aang, Korra, Stevonnie, Kamijou Touma using Imagine Breaker, and Superman and One-Punch Man delivering a fatal blow to both sides of Dimentio's head.

"AAAAA—mmmmmmmppppphhhh!!!" Soon, Dimentio's entire body was smothered in the bright purple adhesive. All exits in all worlds were sealed! Except for one…

With the portal above the castle going unstable, Nebula, Jirachi, Diwata, and Crest combined their power to shrink and maintain it. "We have to let the energy explode somewhere or it'll ruin the path between dimensions!" Nebula shouted. "Jirachi… I…I wish this portal was in a distant, mostly uninhabited dimension where it couldn't possibly do harm to any other dimension!!"

"With the last of my power… I'll…I'LL DO IT!!" Jirachi BURNED with energy, channeling every last ounce of magic and Space Chi before the portal poofed! from existence. (End song.) No longer needing to exert their selves, the kids dropped in exhaust.

Somewhere far away and forgotten

In an incarnation of New York, a sentient polar bear was twerking to an iPad and trying to persuade a bunch of humans that looked like dolls to not build homes in the arctic. They then noticed a portal appear in the sky. "Say, look at that!" Norm pointed.

BOOOOOOOOOOOOOOOMMMMMMMMMMM . . . . . . . .

In the other worlds, everyone braced their guard when the body of adhesive PUFFED like a bubble and threatened to explode. But within seconds, it shrunk and poofed out of existence. "Phew…" Natsu breathed a sigh of relief. And as he looked up at Fiore's blue sky, he and everyone were filled with happiness.

Above the Grand Line's sky, above Karakura's sky, above the Ninja World's sky, above all skies in all the universes, not a single trace of the Multiverse Portal existed. The great rift that had opened their worlds to destruction, opened it to Lord English's control, was gone.

"Sigh…" Stanford Pines sighed. "Finally… the last Darkness is defeated. That means the Protection Charm around Lord English should be gone. The rest is up to you, kids…"

Casino Castle

". . . ." Bill saw the last of Dimentio from his window. Nebula's group was down there on the courtyard. "It's over… they're here! It's over…"

"Calliope…Calliope… …Bill…"

Bill's heart skipped a beat. He whipped around to face him. Lord English didn't move from his position, but he finally spoke comprehensively. "Bill… did Dimentio… really not love my ideas?"

"I…I…I'm sorry, My Lord…"

"Is that why… all of them are breaking my castle? Did none of my minions love my ideas?"

"They…They didn't… Your Lordship… I'm sorry…"

". . . . Did YOU love my ideas, Bill?"

Bill's heart skipped a beat again. English weakly sat himself up. His neck crackled as he turned his head to face Bill. "Bill… why did you leave my head? In my head, you could've watched my ideas form… Did you not love my ideas?"

Bill shivered. The tears leaking from his wide, flashing eyes filled him with fear. "O-O-Of course I did, Your Lordship. I always loved your ideas."

"You…You did… Bill?"

"Of COURSE, Lord English!" Bill cried, struggling to retain the lies. "Your ideas have always been fantastic! And besides, you're All-Seeing! You'd be able to tell if I was lying, wouldn't you? You know I'm telling the truth!"

"…Yes…Yes, I know… I always knew you did, Bill… but why are those people… trying to ruin them? Why…Why is Calliope…"

"Because they're bad people, My Lord. But don't you worry. I'm going to stop them right now. And then we're going to live happily ever after… the way we always wanted!" And with that, Bill turned and walked out of the room.

Outside

"Sigh… you did great, Jirachi." Nebula sat on the ground in rest. "I think it's time I give back the chi I borrowed from you."

"But Nebula, you're nearly depleted. If I take my power back, you won't have anything left for the battle with English."

"You'll need it more than me, to restore the universe. I'm sure everyone else will be just enough."

"Sigh… Okay."

Sunni and Emily faced forward. They were at the top of the Grandfather Tower. They were at Lord English's mansion. The outside was beautiful: pretty neon nightlights, a fountain with a Bill Cipher statue, and bush idols of The Thirteen. "You know, if I were an evil super-being, I would want a mansion atop a tower surrounded by a planet-size fortress, too." Sunni commented.

"This will be my mansion after I become a famous scientist." Emily said.

"Discuss it later, you two." Nebula pulled out the Vanishing Box. "Bill and Lord English must be in there… which means it's time to enact our plan." She opened the box, and out climbed Jessie Sidney and Harvey Harper.

"Yes." Jessie smirked. "It's time to finally complete Operation: Kill Bill."
