Please note this story takes place after the events of Subspace Emissary in Super Smash Bros Brawl but I may tweak that story a little. Don't worry this will be explained. This story is my idea of what an adventure mode would look like in Smash 4. This story assumes that all the characters in Smash 4 live on the same planet, which I designed to fit most of the Nintendo game locations. Bare in mind the locations aren't a 100% accurate. This story also assumes all the Smash characters are part of a team created to protect the planet from dangers. Oh and here, Shiek Zelda, Mario and Dr. Mario are all their own characters. With those facts out of the way, enjoy my story.

Chapter 1: Short-Lived Victory

"AUUUGH"

Another wave of arrows, fire blasts and other types of projectiles struck the large blue warrior. Tabuu was struggling to stand against the huge 38-manned Smash team in the middle of Subspace. Since Sonic destroyed his wings, the Smash Team have him on the ropes. Marth, Link and Pit striking him with swords from all directions. Ness and Lucas using all kinds of PK techniques. Pokémon Trainer constantly switching between Squirtle, Ivysaur and Charizard. Ice Climbers and King Dedede bashing the blue tyrant with hammers. Every time Tabuu launched any type of attack, the Smashers either dodged it or blocked it. Even if by some miracle Tabuu's blasts struck one of the Smashers, it still didn't stop the others from continuing their attack on him.

Mario, who was racing around Tabuu like the rest, evading the attacks and when an opportunity came to light, laid some more damage on Tabuu but Mario knew he couldn't keep doing that forever. Suddenly, the red warrior realized a small detail on Tabuu's massive blue body. A tiny cut with some black liquid leaking out of it, about the size of a Pikmin. In a matter of milliseconds, a plan formed in Mario's head. He looked around and finally caught sight of Marth and Link, sprinting side by side, along with the other smashers. Without wasting any time, Mario used a series of double jumps to get to the two swordsmen.

"Hey Mario, how are you holding up?" huffed Link

"Never mind me," snapped Mario, who didn't stop running. "Do you see that little crack on Tabuu's body?"

The two turned their heads, "Yeah I think I see it" puffed Marth.

"You two need to strike it together," announced Mario, "It might be our only chance to bring him down."

"You got it" said Link, as Mario double jumped away.

"Ready?" asked Marth.

"Let's do it!"

With that, the two swordsmen raced towards Tabuu's side that revealed the crack. They jumped onto the tyrant's body and ran straight up at lightning speed, defying gravity and trying to reach the cut. Tabuu, realizing what they were up to, tried to shake them off with energy blasts, but they dodged each one skillfully. Once they reached the crack, they positioned themselves right at the top of the crack. Then, they pushed their swords together and plunged them right into Tabuu's body, causing a loud scream and a squirt of a black liquid. Without wasting any time, the two grabbed their swords handles and jumped off of Tabuu's body, using gravity to pull their swords down, severely widening the crack and sending black liquid all over the place.

"NOW" Mario shouted.

"PK FLASH!"

Ness held his hands in the air and generated a green, shining orb, sending it directly inside Tabuu and blowing it. Green light flashed out of Tabuu's eyes and mouth once the explosion was triggered. Tabuu began to violently shake and scream, causing Subspace to tremble. Eventually, Tabuu stopped moving for a second then he started disintegrating with blinding blue light, until nothing was left from him except for a pool of black liquid on the ground.

"Well that's that." breathed Samus, putting down her cannon arm.

"It's a good thing you showed up when you did Sonic," said Fox, sarcastically.

"Hey I'm a new recruit in the Smash Team. There was no way I could have known I was needed," defended Sonic.

"Really?" said Captain Falcon, "You didn't notice random black portals appearing all over the planet."

"I was on Mobius Island and there were no black porta-"

"Enough," yelled Snake, "Why don't we focus on getting out of this black hellhole first?"

"I agree," said Pit, "Maybe we can leave from the locations on the planet that were engulfed by the Subspace portals?"

Before anyone could respond, the whole of Subspace began to violently tremble, causing some of the Smashers, like Wario, to fall over.

"Can't catch a break," grumbled Wario to himself as he got himself back up.

"This doesn't sound good." yelled Peach over the rumbling, "I think the portals back home are closing. We need to leave now!"

Without wasting another second, the Smashers began to sprint, trying their best not to fall over from all the shaking.

"Hey look," shouted Mario. "That's the stadium me and Kirby were fighting at before that Subspace Bomb went off."

Kirby made some noises in agreement.

The stadium was just standing there in the middle of the dark, black Subspace, as if it has been built originally in Subspace. As the heroes ran inside the stadium, they found a portal showing their dear planet Earth right in the middle of the fighting arena.

"Alright everyone through!" shouted Mario.

One by one, the fighters jumped into the portal until only nine were left. Mario, Samus, Ness, Lucas, Snake, Pokémon Trainer, Wolf and the two Ice Climbers Just as Snake was about to go through the portal, their surroundings changed rapidly. They were suddenly standing on some sort of platform flying through space.

"Where the hell are we?" shouted Wolf angrily.

"Oh my god," gasped Samus, "I recognize this place. Mario, Ness, Ice Climbers you should too."

"This is Final Destination" whispered Ness, "Where we fought him."

Mario and Ice Climbers' faces darkened.

"You guys aren't making any sense," said Snake frustrated.

"Who is 'he'?" asked Lucas

Suddenly, a deranged laughter was heard.

"How is this possible?" gasped the male Ice Climber, "We killed him, didn't we?"

"Everyone, keep your guard up," ordered Mario. Samus raised her cannon arm. If her mask wasn't broken, no one would be able to tell how terrified she was. Ness and Lucas prepared to perform the PK Fire. Snake pulled out his rocket launcher and Pokémon Trainer pulled out one of his Pokéballs. As if appearing out of thin air, a white gloved, disemboweled hand appeared above the fighters, with the fingers twisting.

"Master Hand?" gasped Lucas, "I thought you were dead."

The hand pointed at Lucas accusingly, "Don't you dare compare me to my idiotic brother," said the hand, "As I am much more superior to him."

"Master Hand is ten times better than you in every way, Crazy Hand," shouted Ness with rage in his eyes.

"I don't know how you survived our last encounter but we defeated you once, we can do it again," growled Mario.

Crazy Hand laughed, his fingers twisting horribly along with his deranged laughter.

"Oh Mario, Mario, Mario," cooed Crazy Hand, "You don't realize that you have less 'troopers' than the last time we met and besides, this time, I brought a friend."

On the other side of the Smash fighters, right next to Crazy Hand, dark, black particles started gathering. The fighters stared confused.

"You think you can defeat us with…this?" said Snake, resisting the urge to burst into laughter.

"Well for your information, 'this' can do more than you think." Crazy Hand turned his attention to the dark particles.

"Master Core," he commanded and then pointed to the heroes, "Kill them."
