Deep within the Special Zones of Sonic the Hedgehog's Universe, A Malevolent Being called Tabuu (the same dude from super smash bros brawl.) and his Minions have stolen the Chaos Emeralds. Knuckles senses this and warns Sonic and Tails,while the 2 are on a fishing trip. Tabuu arrives and introduces himself and wants to test his new Powers on the Legendary Hero of this World,Sonic the Hedgehog. He powers up using the Chaos Emeralds. He beats Sonic and retreats.
Sonic rushes after him and ends up at Rosalina's observatory in the Nintendoverse. Tabuu battles Rosalina and defeats her, He enters the Warp to Star Road and retrieves the Cosmic Stars.Sonic goes after him,but is too late, Tabuu has all 7 stars. He then summons his minions to keep Sonic busy ,while he retreats back to the observatory. Rosalina confronts Tabuu, but with the stars power,defeats her easily.
Tabuu leaves for Hyrule, where he senses another powerful item to get - The Triforce. Tabuu arrives at the Great Temple aka The Temple Of Hylia in Death Valley,where he senses where the Triforce is. Zelda senses Tabuu and sends Link to investigate. Link arrives at the Temple of Hylia and confronts Tabuu. They fight.
Back on Rosalina's Cosmic Observatory,Sonic and Rosalina are chatting about Tabuu and mentions that she has contacted Mario and that he should be arriving soon. Mario arrives and greets Rosie and Sonic. Rosalina explains that Tabuu is an Interdenominational Being from a Realm called Subspace and that ever since he existed,Tabuu has been both Power Hungry and Arrogant. He sees all beings as inferior to him and will do anything to gain Ultimate Power.
Rosalina senses Tabuu in Hyrule battling Link...likely for the Triforce. She sends Mario and Sonic to Hyrule to help Link with Tabuu.
Mario,Sonic,and Link battle Tabuu,but he overpowers them. Suddenly,Samus Aran arrives and demands Tabuu return the Chozo Crystal that he stole earlier. When asked,Samus explains that the Chozo Crystal is an Egg-Shaped Crystal that can enhance ones natural abilities 50 Fold. Tabuu defeats all 4 Heroes and gets the Triforce within the Temple.
After getting the Triforce, Tabuu declares himself to be The Ultimate God!!! Instead of finishing the heroes off, he decides to punish them a more unique way. He sends each of them to a far away World,where they'll be lost forever.
Each hero ends up in a Strange World. Mario lands in the World of Pokemon. Sonic lands in the World of Shinobi,Link ends up in the World of Golden Ax,and Samus ends up in the World of Bayonetta.The heroes explore the Worlds and meet the Main Heroes (Anti-Hero in Bayo's case) of said Worlds. Mario meets Red,the Kanto/Johto Pokemon Champion. Sonic meets Jo Musashi. Link meets with Gilius Thunderhead,and Samus meets Bayonetta.
After talking about the current situation with Tabuu, the Native Heroes (and Anti-Hero) decide to join the fight.
Suddenly a Portal opens in each of the Worlds,mostly thanks to Tabuu tampering with the Cosmic Balance. The Heroes jump into the Portals,hoping it'll take them back to the Nintendoverse...unfortunately,it takes them to other Worlds/Universes instead.
Link and Gilius end up in the World of Fire Emblem,where they run into Lucina. Sonic and Jo Musashi end up in the World of Streets of Rage,where they come face to face with Blaze Fielding. Mario and Red end up in the Realm of Pac,where they meets Pac-Man. And Samus and Bayonetta end up in the World of Soul Calibur, where they meet Sophitia.
After recruiting the Native Heroes to stop Tabuu, more portals open and they take them...to more strange Worlds.

After their journey though those Worlds and recruiting the Native Heroes, The Teams head though more Portals.

As the heroes work their way back home though various worlds and universes, recruiting various heroes to help them fight Tabuu. Tabuu and his Minions are facing off against the Heroes (and villains) of the Nintendoverse, as they put up a resistance against him. With his newly enhanced powers,Tabuu deals with all of them easily.
Meanwhile, Mario's Team ends up in the World of Street Fighter, where they meet and recruit Ryu. Sonic's Team ends up in the World of Bomberman,where they meet and recruit the Bomb Throwing Hero.

Tabuu's minions are destroyed and Tabuu beats them all with his power, but soon gets tired. according to Rosalina, Tabuu can't stay too long outside his Realm,otherwise he'll weaken. Samus deduces that the Chozo Crystal might have increased his powers and abilities, but,as a nasty side effect,also might have increased the strength of his weakness too. The heroes attack Tabuu and damage him.
Tabuu, angered that of his own weakness still exists even with the Ultimate Power in his possession,decides to finish everyone off in his Own Realm,so he teleports everyone to His World - The Realm of Subspace.
Once there, Tabuu decides to let the heroes suffer in his Realm before he obliterates them. He turns Everyone,except for Mario and Sonic into Trophies,which he then tosses in various directions. Tabuu tells Mario and Sonic that the only way to save their Allies is to find their Trophies...which are now scattered thought the Realm of Sub Space. Which he knows will be a great struggle for them,since they are in an Unknown Realm,that they will never survive.
He then realizes that The Chozo Crystal has amplified his weakness, so he discards it. Tabuu heads back tho The Nintendoverse to continue conquering it. Mario and Sonic take the Chozo Crystal and begin their long and dangerous quest.
They face many many dangers,but use the Chozo Crystal to help them survive this Unknown Realm,though use it sparingly,knowing that the Crystal also amps their weaknesses too. They find the Trophies in various places of Sub Space,but each time they find one,they are attacked by a Spirit Clone of their allies.
After defeating a Spirit Clone, they get a Trophy. After collecting All of the Trophies, Mario and Sonic try to find a way out. Rosalina appears and tells them that she finally found them and is relieved that they are alright and tells them that Tabuu has taken over the Nintendoverse with an iron fist and has established a space fortress. She takes them and the Trophies back to her Planetoid.
Rosalina restores the Trophy Heroes to normal and explains that they need to get the Chaos Emeralds, Cosmic Stars, and the Triflorce away from Tabuu to stand a chance. Sonic presents Rosie with the Chozo Crystal and tells her to take care of it. Rosalina takes the Crystal and promises to take care of it.
From his Space Fortress,Tabuu senses the heroes and is annoyed. He telepathically invites them to his Fortress to end things once and for all. Rosalina teleports Mario,Sonic,Samus, and Link to the Fortress,while she sends the rest of the heroes to battle Tabuu's minions, who have occupied various Worlds. She wishes them luck and that the future of the Entire Omniverse is at stake.

The Quartet of Legendary Heroes remember Tabuu's weakness of growing weaker as he remains outside Subspace for long periods of time, so they decide.to play the long game. It doesn't take long for Tabuu to catch on to what the Heroes are doing and Power-Up using the Triforce, Chaos Emeralds, and Cosmic Stars.
The heroes are defeated. Rosalina arrives with Knuckles and the Master Emerald to save the day. Tabuu expresses interest in the Master Emerald and intends on taking it for himself after the battle.
After an explanation, Knux and Rosie keep Tabuu occupied,while The Quartet of Heroes energize themselves with the Master Emerald.
The Master Emerald powers-up the Heroes into Hyper Forms. Mario becomes Mega Mario, Sonic becomes Hyper Sonic, Link becomes a Lighter version of Fierce Deity Link called Just Deity Link,and Samus gains new armor called the Master Armor.
In their new Hyper Forms, The heroes beat the Chaos Emeralds out of Tabuu,causing him to lose power. They then do it again and get the Cosmic Stars back, then the Triforce. With all of the Sacred items back in the hands of good,Tabuu is weak now.
Tabuu is destroyed and his Fortress starts to crumble. Rosalina teleports everyone and the Sacred Items back to her observatory. With Tabuu destroyed,the minions explode into nothingess.
Hours later, on Rosalina's planetoid. Rosalina addresses the Heroes and thanks them all for their help. Link uses the Triforce to restore the Nintendoverse. Rosalina teleports the Cosmic Stars back to the Star Road. Mario,Sonic,Link,and Samus are back to normal.
Sonic has the Chaos Emeralds in hand,while Knuckles has the Master Emerald. Sonic and Mario say their good-byes to their newfound allies before Rosalina transports them back to their own Worlds and Universes.
Before going their separate ways,Mario and Sonic promise to have another cool adventure together one day.
After all of the Heroes are gone, Rosalina returns to her job as Guardian of the Nintendoverse.
The End!!!
