Super Smash Bros:

Return of the Subspace Emissary

Chapter 40: The Finale Part 4: For the Sake of All Worlds

Mario and Bowser stood there in shock as Dimentio floated in front of them.

"How is this possible? You were destroyed!" Mario exclaimed.

"I was for a short while but the Chaos Heart helped" Dimentio explained. "Before my soul departed, the Chaos Heart reacted to my death by bringing me back."

"Sounds like something that would only happen in one of those Fanfiction things" said Wolf. There was an awkward pause.

"Anyway," Dimentio continued, "Unfortunately, I was trapped here in Subspace. I could've escaped but Tabuu would've killed me for good if he was aware of my presence."

Bowser asked "So you've been here this whole time?"

"Correct. I even witnessed the final battle against Tabuu. Once he died, I took over and set about bringing the Primids back. Sadly, they weren't all in my power. I was however able to make my own versions of the Subspace Bombs to rip up the land. I wanted something that would catch your attention and bring you here so you could be defeated" Dimentio explained.

"Well, now we're all here and we'll kick your butt!" yelled Fox.

"Yeah. Three people defeated you when you were super powerful. This won't even be a challenge!" declared Sonic.

Dimentio waggled his finger. "I wouldn't be so optimistic. After all, I was able to destroy a whole world."

Sora stared st him. "What? You destroyed my home?"

"Of course. Once I realised the host was there, I set about ruining it. But then I noticed you. The Keyblade Master. With your help, I knew things would be easier. So, I told you the Super Smash Bros were responsible so you would work for me." Dimentio began to chuckle. "Ironic, isn't it? The one who saved all worlds from impending darkness ends up dooming them to it."

Sora couldn't believe it. He collapsed in despair. The others looked both angry and confused.

G&W beeped which everyone didn't understand but Meta Knight translated it as "What do you mean 'host'?"

"Well, my plan to get revenge is to destroy all the worlds and rebuild perfect ones to rule over. Without the Chaos Heart, I set about getting the next best thing, Tabuu!"

Everyone jumped in surprise. "Tabuu? You're intent of bringing that madman back?" demanded Ganondorf.

"Well, not completely. His soul will exist in another body but I'll control him. Of course, I needed something else to transfer his soul into the host. The Pure Hearts."

Mario looked confused. "But the Pure Hearts are objects of light. How would they bring back an evil person?"

Dimentio spoke again. "Not the exact Pure Hearts. Seven substitutes that existed in the bodies of seven different maidens. A bit like the Princesses of Heart. Eh, Sora?"

Sora recoiled in horror. He was beginning to see what he had done and now the worlds were paying the price.

"So, these hearts… I think I can guess whose bodies they inhabit" said Pit.

Dimentio smirked and snapped his fingers. On one side of him appeared the trophies of Peach, Zelda and Samus. On the other side were Mist and Amy.

"You let them go, right now!" threatened Ike.

"I'm afraid I can't do that" Dimentio said calmly.

Wario scoffed. "You seem to be forgetting that you have five. Not seven."

"Well, I'm prepared."

Dimentio snapped his fingers again, causing an echo.

In the jungle, Krystal was watching the monkeys rebuilding their homes. Suddenly, she vanished in a flash of purple light.

In Skyworld, Palutena was sitting on her throne, wondering how Pit was. Then, like Krystal, she vanished in a purple light.

Back in Subspace, their trophies appeared next to Dimentio. It was Pit and Fox's turn to get angry now.

"How did you do that?" asked a confused Nana.

"Sora was able to place invisible devices on them that turn them into trophies and bring them here. A bit like the badges that Dedede made, only with a different reaction. I only had enough power to make two" explained Dimentio.

He continued, "Now, I have all seven and the host!" he cried.

Yoshi looked about nervously. "Who's the host?"

"I'm glad you asked" Dimentio sneered, snapping his fingers once more. A scream was heard from Kairi's direction as she floated up into the air. Sora tried to save her but was knocked back by a forcefield.

Once she was in the air, the seven trophies began to circle and glow as Dimentio chanted.

"Seven purest hearts. Use the surrounding darkness to resurrect the Subspace entity!"

Seven lights emanated from the trophies, piercing Kairi, causing her to cry in pain. Her screams were absolute torture to the heroes, who could do nothing to save her.

Dimentio spoke again. "Here is your new body, TABUU!"

Kairi was engulfed in a blue light, as the trophies flew upwards, suspending over her. As the light vanished, Kairi was different. Her body was how light blue and looked like she was made out of data. She also had a pair of butterfly wings on her back. She'd probably be beautiful if it wasn't for the cold stare in her red eyes.

Dimentio began to cackle, insanely. "I give you, the destroyer of all worlds, KAIBU!"

The heroes stared at the newly transformed Kairi and prepared for the inevitable.

"Now, Kaibu, destroy these vermin!" Dimentio ordered, but she just floated there. "Didn't you hear me? I said destroy them!" Dimentio repeated. Still, she did nothing.

Dimentio eventually lost his cool. "I said destroy. You know, it's like annihilating, obliterating. JUST KILL THEM!!!"

Kaibu turned to Dimentio and suddenly grabbed him by the throat. For the first time ever, Dimentio looked scared. Before he could ask what she was doing, he began to get electrocuted. Next thing he knew, he was glowing blue before exploding.

"Woah, she's gone completely berserk!" cried Falco. That wasn't the end of it. Kaibu turned to face the heroes. They knew what they had to do. The team, except Sora, jumped at her and prepared to fight.

Mario and Luigi tried to hit her but she teleported behind them and smacked them away. Bowser and Link had a go but she charged at them with some sort of blade. Both were too slow and slashed upwards.

Ganondorf and Toon Link jumped from behind but she turned around, turned into a shark shaped blade and shot straight through them. Pit flew at her but she threw a whip at him, which caught him and she threw him into the Ice Climbers.

She then pulled out a circular spiky disk and threw it at R.O.B who managed to avoid it but got Kirby. The robot made an attempt of attacking her while her defences were down but the disk returned like a boomerang and knocked him over. Meta Knight flew at her while Dedede tried to attack from underneath but a forcefield made from electricity surrounded her and badly injured the two before they were sent flying.

Olimar threw Pikmin at her while Fox used his blaster but they didn't do anything. Before they knew it, Kaibu was repeatedly karate chopping them. The final hit sent them flying, nearly hitting Falco and Wolf, who ran as fast as they could to attack her but she fired several bullets at them from her hands. They managed to use their Reflectors in time but were unprepared for the huge ball of energy she fired at them.

Captain Falcon ran full speed and was able to get a hit. To his horror, she didn't feel a thing. Kaibu then transformed into a yellow object that grabbed hold of the F-Zero pilot and bashed into the ground. He was thrown upwards, eventually crashing into Pikachu. Red pulled out Squirtle and the turtle used Waterfall to reach her. To both their surprise, she sent out different copies of herself that did damage to both Pokémon and Trainer. A few even hit Lucario who was trying to do a sneak attack.

Jigglypuff floated towards her but a bunch of lights sparkled for a quick second before blowing up and sending the puffball falling through the air. Marth would've caught her but he was hit by the explosions too. Ike, Ness, Lucas, G&W, Snake and Sonic decided to join up for a final assault but to their surprise, Kaibu became gigantic and fired lasers from her eyes that sent them sprawling into the rest of the heroes.

They were all weak and had barely got any hits and even those did nothing. It seemed like they had lost. Mario tried getting up but fell back down.

Sora was watching the whole thing. He would've fought too but he was too distraught with helping the bad guy. Suddenly, images of his friends appeared before him, all saying the same thing…

"Don't give up, Sora!"

The last one was Kairi who smiled at him and said "Don't lose hope, Sora. I need you to save me, the Super Smash Bros and the worlds. Don't let despair cloud your heart."

Sora nodded. He never gave up before and he wasn't going to start now. He looked at Kaibu and noticed the seven trophies hovering over her. He stared at his key and decided to give it a shot. He threw it between the trophies. It hit something invisible that caused an explosion. The trophies fell to the floor while Kaibu screamed in pain.

The others looked up and ran to the fallen trophies.

"What happened?" Ness asked.

R.O.B was scanning Kaibu. "Her power level has dropped. The trophies must've been supplying her with energy" he stated.

Mario turned to Sora and the two exchanged thumbs up. Mario then touched the base of Peach's trophy. Link, Pikachu, Fox, Pit, Ike and Sonic did the same thing with Zelda, Samus, Krystal, Palutena, Mist and Amy respectively.

The girls seemed a bit confused but the heroes all said the same thing. "Stay back!"

The girls retreated except for Peach, Zelda and Samus.

"We'll fight too!" they exclaimed.

All 36 heroes turned to face the weakened Kaibu.

"You ready, Sora?" asked Mario.

"You bet, Mario" he responded. "Let's do this. For the sake of all worlds!"

Bowser attacked first. Kaibu threw the boomerang disk but Bowser dodged it and slashed her across the face. She was knocked back in pain and Captain Falcon came from behind to knee her in the back. She was thrown forward and hit by the disk on its return. She was about to fire a barrage of bullets at them but Diddy latched onto her face and began to smack her. She threw him off but DK caught him in his arms. He followed that up by spinning horizontally, damaging her.

Fox and Falco attacked her from opposite sides by dashing past her, making an X shape in their after wake before turning around and firing their blasters. She tried sending copies of herself at them but Ganondorf jumped and slammed his fist into her gut, sending her crashing into the ground. She pulled out her blade and sped towards Ganondorf who sidestepped the attack. When Kaibu's back was on them, the Ice Climbers attacked simultaneously with their hammers. Their combined strength added to Kaibu's already high damage. She turned towards them and knocked them away with a swipe of her hands but Ganondorf was there to catch them.

Ike used Aether to gain height and bring his sword down on her but she blocked it with her own. Ike was too slow to counter her attack. She approached him and was about to bring the blade down on him when Jigglypuff slapped her from behind. Kaibu became distracted and tried slashing Jigglypuff up with her blade but she was always dodging. This gave Ike time to fully charge up his Eruption move and engulf Kaibu in flames. Once they cleared, Kaibu was disoriented so she wasn't prepared for Kirby and Dedede using their hammers to smash her from both sides.

As she shook away the two hammer wielders, Link threw a bomb at her while Lucario used Aura Sphere. The combined attack attracted her attention and she threw her whip at them. Link was caught but before he could be thrown anywhere, Lucas managed to destroy it with a PK Fire. Kaibu became enraged at this and charged at the three but was stopped when Luigi knocked her away with a Luigi Cyclone.

She was sent towards Mario who jumped and brought his fist down on her head, sending her plummeting to the ground. The result was an impending explosion. Kaibu got back up and turned her hateful gave to Mario. Before she could do anything though, Marth came from the side and repeatedly attacked her with his sword, not letting her retaliate. However, she broke through and grabbed him by the throat. She was about to serve Marth the same treatment she gave Dimentio when Meta Knight attacked from behind. She turned her attention to the masked swordsman and threw Marth at him, knocking the two out of the air and towards the ground.

She was then attacked from behind again by G&W with his goldfish bowl. She turned and fired three balls of energy at him but he absorbed them with his Oil Bucket. He threw the oil all over her, knocking her in Ness' direction who pulled out his baseball bat and swung it at her. She crashed into the ground with a thud. She got up with her red eyes glowing with hate when she found herself covered in Pikmin. Olimar stood nearby looking quite smug. They attacked her using all means until she used her electric forcefield to kill them. She was about to do the same to Olimar but Peach stopped her by swinging her golf club into her face, sending her sideways.

While she was in the air, Pikachu used Thunder to crash into her. It made her fall to the ground faster and Pikachu rolled out of the way, barely avoiding her. As she got up, Pit ran at her and the two exchanged blows with their respective blades. Kaibu was getting steadily weaker so Pit spun his blades in a ring formation and knocked her backwards towards Squirtle who swiped across her face with his tail before head butting her with all his strength. Kaibu was getting frustrated and threw Squirtle as far as she could. Thankfully, R.O.B caught the turtle and fired a fully charged laser which went straight through where her heart would be.

She fell to the floor in pain, allowing Samus to wrap her Grapple Beam around her and bring her in. As Kaibu came close, Samus shot out her foot, knocking her off the beam and sliding across the floor towards Snake who placed C4 on her before backing off and setting it off. Kaibu blew the dust away and, using her wings, flew up and began to charge something up. Before she released it, a blue blur went straight through the left wing, breaking it. It uncurled to reveal Sonic, smirking at her. Kaibu tried to attack using only one wing but Sora jumped and broke the right one. With noting to sustain her, she fell to the ground while Sora repeatedly struck her across the chest with his Keyblade. They both crashed into the ground.

Sora got back up but found Kaibu with her blade to his neck. Before she could attack, Toon Link threw a bomb that gave Sora the cover to escape. Kaibu charged at Toon Link with the intent of chopping him up but Wario jumped in the way and let off a huge fart that blew Kaibu away, as well as making her recoil with disgust. In her weak moment, Wolf jumped and kicked her across the face before bringing his claws down on the same spot he hit. Kaibu tried to attack but Yoshi wrapped his tounge around her, preventing her from moving. She then saw Zelda running towards her with her hands glowing. Zelda skidded to a stop and let her magic out, knocking Kaibu out of Yoshi's tounge.

The data monster got back up, badly wounded, but she wasn't going down so easily. Her body began to glow red as little sparks of energy emanated from her body.

"What's she doing?" asked Pikachu.

"She's about to blow up and no doubt she'll take all worlds and us with her!" Snake exclaimed.

Sora looked about for anything that could help and he spotted one Smash Ball. He knew that wouldn't be enough to stop her. But a sudden idea came to his head. It might not work but it was worth a try. He grabbed it but didn't break it. He motioned to the others.

"Hey! Everyone touch this!" he cried.

The others didn't know where he was going with this but did it anyway. Everyone managed to touch the item and they all began to glow.

"OK, now, everyone transfer your power to Mario" Sora continued.

Now the others were confused but Kaibu was beginning to shake so the tried. They stretched their hands out and their power seemed to leave their bodies and enter Mario's. He was beginning to glow even more and now, he seemed to understand Sora's plan.

"Alright, Kaibu! I'm ending this now!" he yelled.

He jumped into the air, forming a white sphere in his hand that was glowing. He then threw it downwards crying "SUPER ALL STAR BOMB!!!"

The bomb hit the ground and exploded with a blinding flash of light that engulfed the heroes, the girls and Kaibu. No one knew what happened next.

When the heroes woke up, they found themselves in a green field and the sun was high in the sky. The problem was they were surrounded by Primids. To their surprise though, a pillar of light was standing near them that spread out wiping the purple monsters out. Even though they didn't see it happen, they knew what the light did.

It spread over the whole world and beyond, wiping out the Primids and restoring any damage the Subspace Bombs did. All over the world, citizens cheered for joy. The Mushroom Kingdom, Hyrule, the monkeys, the robots, Sonic's friends and everyone else celebrated. It was over.

The Super Smash Bros danced for joy and exchanged hugs. Even the villains couldn't resist but smile. The only one who wasn't was Sora. He was standing over Kairi's lifeless form. It had looked like it had all been too much for her. Sora tried his best not to cry but he couldn't help it. He may have saved the worlds once more and no doubt he would end up back in his own world soon enough but he had still lost Kairi. The others stopped their celebrations in respect and Mario tried to comfort Sora.

"It's OK, Sora. Let it all out" the plumber said.

Sora struggled to speak through the tears. "I never got to tell her…how much I cared for her…how much I loved her…I LOVED HER!!!"

He broke down into even more sobs, prompting the boys to hang their heads in sadness while the girls cried. An eternity seemed to pass until they all heard someone say "I love you, too."

They all stopped and saw Kairi's eyes open. She slowly got back up and smiled at Sora who was still in shock. He soon smiled and the two embraced. The heroes cheered as they kissed. Now, everything had worked out.

Suddenly, Sora and Kairi began to glow. They stopped their kiss to turn to the others.

"It looks like we're going home" Kairi said.

"Sorry for being such a jerk" Sora apologised.

"It's OK. You were being used" Luigi said. "I know how it feels."

"I guess this is goodbye" said Kirby.

Sora nodded and gave the heroes thumbs up. They all replied with the same thing "Goodbye Sora and Kairi!"

The teens waved goodbye as the light covered them up completely. When it stopped glowing, they were gone.

Mario sighed. "I guess it's over."

Bowser smirked as his Koopa Clown Car came from the sky. "Got that right, plumber. Now, I'm gonna kidnap Peach!"

He turned around but was surprised to see Peach already in there. "Come one, then. Let's get this done quickly" she said.

Bowser shrugged and jumped in and flew off. "See ya Mario!"

Mario smiled. "Come on, Luigi. Let's go save her without any interruptions!"

Luigi smiled back as the two gave chase, with Yoshi lagging behind. "Wait up guys! I'll help too!" he yelled after them.

Link turned around and saw Ganondorf walking away, with Zelda under his arm.

"Ganondorf. Get back here" Link chuckled.

The dark wizard turned slowly to see Link standing there with his sword ready, before running off. Zelda couldn't help but laugh as she was carried off.

"Come on, Link! You're faster than him!" she yelled. Link proceeded to chase after her, with Toon link in tow.

Samus pressed buttons on her wrist and her ship came down from the sky as she turned to Pikachu.

"Listen, Pikachu. I'm sorry for yelling at you" she apologised.

Pikachu shook his head. "It's OK. Come on, let's go home!" he responded. Samus smiled behind her helmet as they went into her ship and flew off.

Fox, Falco, DK, Diddy, Wolf and Krystal then saw the Great Fox come down, with Peppy speaking over the loudspeaker.

"It's good to see you fellas are alright" he said.

"Thanks, Peppy" replied Fox. As he, Falco and Krystal boarded the ship; he turned to the other three. "Hey, DK, we can drop you and Diddy off at the jungle" he cried.

The two monkeys nodded and followed them, while Wolf skulked off.

"I don't need you pity, McCloud" he said.

"Are you sure?" Fox asked. "We won't turn you in. I swear."

Wolf glanced at the ship once more, sighed and boarded.

Kirby walked up to Palutena and whispered, "I hope you don't mind my asking but do you have something you want to tell Pit?"

The goddess glanced at him and then at Pit. She walked towards him and said "Pit, I need to tell you something, in private."

Pit wasn't sure what she meant until she gave him a peck on the cheek. Blushing, he followed her up into Skyworld.

Kirby smiled as they left. He then heard something and turned to see the Halberd, with Meta Knight, Dedede, Ike, Marth, G&W and Mist boarding.

"Come on, Kirby. I'll get us back to Dreamland!" Meta Knight yelled. Kirby nodded and followed suit.

Sonic smiled as he saw his friends depart before turning to Amy. "I'm glad you're safe" he said.

Amy giggled. "Thanks, Sonic. And do you think that maybe…"

Before she could finish, Sonic had already taken off. Amy got annoyed and chased after him.

Wario heard a car horn and saw Waluigi in the Wario Car waving to him.

"Hey, bro. Where've you been?" the lanky brother asked.

"Saving the world. Now come on, I feel like a garlic pizza with extra garlic" Wario responded.

Captain Falcon climbed in with them. "You wouldn't mind dropping me off in Mute City, would you?" he asked.

"Sure, why not. I feel like a vacation" Wario said, as they drove off.

The Ice Climbers and Lucario decided to head back to the mountain to check on Articuno. Plus, Nana wanted to do something to get her mind off of Subspace.

Ness, Lucas, Red and Jigglypuff began to walk back to Onett for something to eat and a game of baseball.

Olimar and R.O.B were debating about how they were going to get back to Angel Island when a chopper appeared, dropping a ladder for Snake. As he began to climb, he turned to them and asked them if they wanted a lift. Nodding, the twosome joined him as they climbed into the chopper and took off.

As the heroes parted ways, they were all thinking the same thing. No matter what evil stalked the land, they were there to protect it. If there was anyone so mad enough to threaten it, they would join together once more. After all, they were Super Smash Bros!

The End!
