Super Smash Bros. Ultimate: Definitive Edition/Final Smash

Final Smash is a mode in Super Smash Bros. Ultimate: Definitive Edition. It acts as a remake/re-imagining of World of Light, though taking more inspiration gameplay & story-wise from Subspace Emissary. (Note: I'm not a professional writer. Sorry if you find any problem with how I wrote or paced this story.)

Changes from World of Light

 * The gameplay has been changed into playing similarly to Subspace Emissary, being a side-scrolling adventure game similar & focuses on platforming & defeating groups of enemies, while also collecting spirits from the Light & Dark Clones, which can be equipped for each character.
 * Doesn't have long load times.
 * You start with the Mii Fighters, instead of Kirby to get rid of the Sakurai bias.
 * The Light, Dark & Light/Dark Realms are now split into levels with sections that end with a boss.
 * There’s more story cutscenes, though the characters are silent like in Subspace Emissary as well as avoid complaints of bad dialogue or delivery & are done in real-time instead of pre-scripted to keep consistency.
 * Galeem & Dharkon are given more personality & clearer motivations, though retaining their amorality.
 * You can bring up to 3 characters into boss fights again with the bosses' health bars increased to compensate.
 * Any Assist Trophies that are playable in Assist Smash can help during levels & boss fights.
 * The freed bosses will also partake in some battles.
 * Stocks are removed, so the difficulty could be based around the level design & challenges, though you do lose points for every death.
 * There's only 2 endings: The Normal Ending & The True Ending with the bad endings removed due to being inconsequential.

Plot
The story begins with Master Hand & Crazy Hand watching over the various worlds after the events of Subspace Emissary, thinking that with the newcomers that they would be better prepared for any danger. They head to check Master Core & are shocked to see that it’s been stolen before the former is snatched by a set of wings, while the latter is snatched by tentacles afterward. It cuts to Kirby sleeping under a tree until he's woken up by Meta Knight, King Dedede & Bandana Waddle Dee where they noticed that Master Hands are attacking Dream Land. They then get a call from Fox who wants everyone to meet him, Falco, Wolf & Krystal on a cliff, causing Kirby, King Dedede, Meta Knight & Bandana Dee to get a headache upon Fox showing them Galeem. Meta Knight then takes the rest onto the Halberd to meet up with the others.

It cuts to a close-up of a blaster aimed at the horizon, revealing Fox as the camera then zooms out & pans to the left, revealing that he's addressing some of the playable cast, all of whom have been summoned to the edge of a cliff, though some are rubbing their heads as they recover their headaches. The camera then pans upward to reveal Galeem, who's currently accompanied by a looming army of Master Hands that's slowly approaching the mount before several Master Hands rush at them, while every other Master Hand surrounding Galeem slowly disintegrates into a glowing, blue streak of light that ends up being absorbed by Galeem. This causes Shulk envisions the downfall of his comrades & points towards Galeem as everyone stops & sees a singularity between Galeem & his now-absorbed Master Hand army as he creates a black hole, which soon collapses, creating an array of beams of intense light.

The beams of light rapidly approaching the cliff where some of the fighters are situated. As they aim downwards to consume the fighters with Waluigi being the 1st victim, Link successfully deflects 3 beams before succumbing to a 4th beam. Samus attempts to fire at the beams, but it's to no avail before she's engulfed by one. Both Zelda & Mewtwo simultaneously attempt to reflect the beams, before being immediately decimated. Sonic, Tails & Pikachu attempt to outrun the beams, with the former attempting to assist Pikachu in escaping, but all 3 are ultimately disintegrated. Donkey Kong goes forward to try to deter the beams of line. King K Rool, knowing that DK had a better chance of survival than the rest, took a beam instead. Donkey Kong, seeing his sacrifice, tried to grab Diddy Kong to escape but both get evaporated before he could reach him, but Diddy manages to escape. Bayonetta successfully dodges 3 beams at once, but is disintegrated by yet another beam of light as soon as she retains her original form. Bowser attempts to fight off Galeem's beams of light, only to fail & be consumed. Captain Falcon attempts to get into his Blue Falcon in order to escape the onslaught, but both he & his vehicle are destroyed just as quickly. Lucario teleports away from 1 of the beams, finding itself behind Greninja, who jumps upward to successfully escape from a beam. Unfortunately, this was all for naught as the beam Greninja hops over ends up engulfing Lucario instead & yet another beam of light reaches Greninja in midair after Zero pushes him out of the way.

The Inklings & Octolings use their Splattershots to shoot ink onto the ground and then try to hide in it, only to have yet another of Galeem's beams of light ram into the ground, decimating them. Falco is shown in his Arwing attempting to make his escape, but his exceptional flying skills are just not enough to evade the persistent tendrils of light & ends up getting taken down by multiple beams all at once. Bomberman had strewn bombs prior to the combined attack & attempted to set them off but the beams of light evaporated him before he could. Ness & Lucas all tried to use PSI Magnet to to absorb the blast which they were marginally successful for the 1st few seconds but it overloaded their barrier & were consumed. Min Min was able to deflect 3 beams before being consumed herself. Fox tries to use his Reflector, but it breaks & is destroyed. Captain Toad tries to rush Peach to safety & attempted to act as a shield when the beam approached but all were evaporated. Daisy foolishly tried to take it on with her Frying Pan & was instantly evaporated as she swung her pan at the beam of light. Ganondorf had transformed into his Beast Ganon form to try & repel the beams of light, but was decimated. Pit flies away, bestowed unto him by Palutena, who, along with Medusa & Viridi attempts to buy him more of a chance to escape by summoning a Reflect Barrier in the hopes of suppressing Galeem's attack, but simply vaporized by a beam, which causes him to lose their ability to fly, resulting in him getting wiped out by a beam of light in midair. A lone cardboard box is shown on the cliff's edge, hiding away Snake, only to have a beam prove his attempt futile. Both Rosalina & Diddy attempt to fly away from the onslaught, but are eventually swallowed by the beams. Finally, a group consisting of the Ring Fit Trainee, Duck Hunt, Banjo & Kazooie & Isabelle eventually end up getting engulfed by the light.

Meta Knight manages to fend off 2 beams before being engulfed. Seizing the chance, Dedede used his Jet Hammer to launch Kirby high into the sky so Kirby could use his warp star to escape. He was evaporated, knowing there was some hope. After deviating from many of them, the frequency of the Warp Star's blipping noise increases rapidly in intensity as Kirby attempts to push its power to its absolute limit, resulting in it moving at warp speed, temporarily warping Kirby to another plane of existence, which Galeem notices & chases after him as his beams are then shown atomizing multiple non-playable characters into oblivion. Galeem chases after Kirby & finally consumes him after going through several worlds. Eventually, the deadly light erases the entire Omniverse, leaving nothing in its wake. The planet on which the ordeal started is now left as nothing more than a barren wasteland, with its remains currently inhabited by the now-hostile souls of non-playable characters. Galeem then reappears, wiping his core as it places Kirby in his spot & creates clones of everyone using his essence & Master Core to capture the spirits. It then starts crafting its new world, using parts of the world it destroyed & using Master Hand to place them, while sending everyone to capture all spirits to consume the darkness within them.

Later on a field near the Find Mii universe, a dark portal as Dharkon has its eye on 1 of its tentacles to look around to what Galeem has done & notices the Mii Brawler, Mii Swordfighter & Mii Gunner looking around for more spirits. It gets the idea to uncorrupt them to give Galeem some trouble, so it would be easier for it to steal some of the characters & locations Galeem has & then grabs the Brawler as it breaks its control over him before doing the same doing the same to the Swordfighter & Gunner before disappearing. Once freed, they look towards a vast landscape consisting of various areas, some of which are recognizable as coming from the fighters' old worlds & now have to find & rescue everyone in the game.

1-1: Perilous Prairie
As they enter their home universe in Perilous Prairie, some Light Clones notice & attack them due to not giving the aura Galeem gave them. After defeating them, they notice the clones contained spirits & each decide to use them to help them in case things get hairy as they continue to wade through Perilous Prairie. The Miis eventually find Poochy & Nintendog getting into a little scuttle, which they were able to settle before the 2 attack them with Poochy in particular trying to push them down a cliff, only for the Swordfighter to use his sword like a stick & throws it to them, causing the 2 dogs collide with each other & pass out. Isabelle then appears & lunges at them. Isabelle falls over as the 2 dogs then wake up & greet the Miis as they then pet them. Poochy & Nintendog then start licking Isabelle as she wakes up & rubs her head. She then hugs the Mii Brawler as she cries before calming down & joins them as they head towards the Bewitching Bog.

1-2: Bewitching Bog
After reaching the end of the level, they notice the Nintendog is being grabbed by a Piranha Plant, while Poochy is barking at a bush. A goose then pops its head out & honks at Poochy before taking the Swordfighter's sword before he gets it back & a fight breaks out. Goose is knocked into Piranha Plant as they fall into the bog. The Miis & Isabelle then jump inside to rescue them as Goose then recovers & helps them pull Piranha Plant out of the water. Piranha Plant then wakes up & eats a Gastly that tried to sneak up on them as it & Goose then joins the others.

1-3: Ransacked Ruins
They reach the ransacked where they get attacked by Tetriminos that start falling from the sky as Goose finds the box using to spawn them & takes it towards the others for destroy it, but after breaking, it reforms, now out of Galeem's control, which everyone decides to use in certain cases, though they have to be careful not to make a straight line or else they'll disappear. After reaching the end of the level, they see several Gastlys flies in their direction, but realize that they're not attacking them, since it's revealed that they're being chased & eaten by Pac-Man due to a force of habit who then attacks them. Pac-Man then collapses as Galeem's control breaks before waking up & thanking everyone for rescuing him & joins the group as several flies follows them.

1-4: Restless Rise
The group then reaches Restless Rise where they noticed that a Master Hand is commanding a group of enemies & have to reach it. The group reaches the Master Hand clone, only for them noticing that it's holding something, which it then releases to reveal the Angry Video Game Nerd who then attacks them as some enemies join him. The Nerd then collapses as his glasses fall out & the Master Hand tries to crush him for failing it, but is stopped by the group. The Hand explodes & the Nerd wakes up after Goose pecks at him and looks around, thinking he had too much to drink & gets startled by the spirits that were rescued. He then joins the group as thanks for saving him from the Hand & they head to the Forest of Sorrow.

1-5: Forest of Sorrow
After reaching the end of the level, the Nerd notices a bunch of flies buzzing around himself & tries to swat them away. The rest of the group then start noticing flies buzzing around them as well & get ambushed by a massive hand holding a flyswatter. The Hand collapses as the flies plummet to the ground, which surprises the group, realizing that the 2 are connected. It then recovers as the flies fly back up & joins the group. After reaching the end of the level, they get attacked by various fists, feet, torsos & flowers that come from the trees or from the sky, which they learn came from the Ring Fit Trainee who then attacks them. She then collapses as the flame that she was burning fades & drops Ring. Mii Gunner picks up Ring to wake him up, which she does & then wakes the Ring Fit Trainee. She then gives everyone a smoothie as a thanks, then joins the group & scouts ahead to stay active.

1-6: Castle of Darkness
The group reaches the Castle of Darkness which they find rather particular since Galeem is supposed to represent light & begin their journey inside. Galeem, meanwhile, gets alerted of their presence while it began to notice some fighters are missing & sends a rather an orange spirit orb into the castle. The group eventually reaches the top of the castle where they notice the spirit orb, which forms into the Dark Emperor. The Brawler, Swordfighter & Gunner walk in front of the group to confront him & the battle begins. He collapses to the ground as the fighters soon follow. The castle then collapses as the Dark Emperor then wakes up, grabs the group & takes them out of the area. Meanwhile, the group is having a nightmare where Galeem is stabbing them with a lance made of its wings. They all wake up, surprised that they did it at the same time & noticed that the Dark Emperor has been protecting them from Light Clones, but are thankful as they then head on to the Mushroom Kingdom.

2-1: Toad Town
The group reaches Toad Town where they try to look for anyone & end up finding Yoshi who attacks them. Yoshi collapses as the aura fades away & some of the group pick him up & carry him to 1 of the Toad Houses. He then recovers as he jumps in place to thank them for rescuing them & joins them to look for Mario, but are forced to retreat to Peach's Castle as they would know Peach will probably be there unless she's with Bowser. Before they close the doors on Peach's Castle, the Gunner notices a Lakitu has survived, but isn't giving off Galeem's aura, so she then grabs it as Yoshi then grabs her before the rest lock the doors.

2-2: Peach's Castle
The group meets Peach in the castle foyer who presses a button on the wall, opening a trap door below them, causing them to fall with Yoshi using his Flutter Jump to stay up, but fails & falls in too. She then laughs, but gets hit with a Spiny as the Lakitu didn’t fall, plucks a turnip & throws it at it, causing it to fall down. Peach then sends several Light Clones & other enemies to the dungeons to make sure the group is dealt with.

The group then wakes up, noticing that they all are in Peach’s dungeon & then catch Yoshi & the Lakitu. They then hear several footsteps from upstairs & the Nerd signals them to head to the top of the castle to rescue Peach & start fighting their way as well as the Lakitu ingests a spirit as well. After reaching the end of the level, they noticed a Chain-Chomp that survived with the Lakitu removing its post as it runs up the stairs while the group, except the Lakitu, hangs on, grabbing & eating a spirit from a dead Light Clone along the way as it felt the energy emanating from the group. They reach the top of the castle where Peach sends some enemies to deal with them, while signaling Bowser’s Airship to help her. After defeating the enemies, Peach then fights the group while Bowser’s Airship & fires at them. Peach then falls off the top of her castle, but is saved by a mechanical arm from Bowser’s Airship & taken in. The group feels that Peach has been freed & jump to the ship, so they could meet up with her before it gets too far with the Lakitu grabbing the Chain-Chomp.

2-3: Bowser's Airship
Peach is locked in a cell after the Light Clones notice that she's not giving off Galeem's aura as they headed off Bowser's Castle to lock her up in a cage. She finds a secret passage in her cell after thrown in & goes inside of it that Light Clones of Mario & Luigi notice this & tear off the cell door & alerted the others, which the group who are hiding at the moment find out after seeing the Light Clones feel tense. After reaching the end of the level, Peach reunites with Mario, kisses his forehead as he takes his hat & joins the group. She then notices a claw coming at her & dodging out of the way to reveal Bowser Jr.. Bowser Jr. falls out of his Klown Car & it lands on him. The Chain-Chomp starts licking him to wake him up, which works as he reluctantly thanks the group for saving him & joins the group to rescue his papa as well as begrudgingly Mario & then signals them to retake the airship, so they could head to the castle with little trouble. Galeem, meanwhile, notices Bowser’s Airship is going in a circle & heads off to investigate. After defeating all enemies, Bowser’s Airship is shot by a beam of light, which the group turns to see Galeem who then launches its wings like drills in the ship’s hull & the group braces themselves as the ship crashes. They then head to Bowser’s Castle as Galeem checks the wreckage to make sure they’re dead.

2-4: Lava Fields
As they reach the castle, the group realizes that they need some way to cross the lava moat. Yoshi shows everyone the boat that's usually there when Mario, Luigi or Toad use to rescue Peach & use it to cross it while dealing with more enemies.

2-5: Castle Gates
As the group reaches the gates, another Master Hand surprises them as a fight breaks out. The Hand explodes & they notice there's Thwomps on the ceiling as the Lakitu throws a Spiny & sees it crushed by one. They notice a Light Clone of Bowser, knock out & throw him into the Thwomps, defeating all but one. They all check on it & it wakes up as it slides forward & the group dodges out of the way, but learn that it was because a group of Light Clones were going to ambush them. The Thwomp then joins the group as a result. Bowser, meanwhile, discovers the group, surprised that Peach is with them & sends his minions after them.

2-7: Iron Works
After reaching the end of the level, the group encounters Birdo with Mario, Luigi & Peach coming to the front as they've fought her before & she attacks them. Birdo then collapses as Yoshi approaches her. She then wakes up & hugs him, thanking him & the others for rescuing her & joins them on their journey.

2-8: Castle Towers
After reaching the end of the level, the group notice that 1 of the Hammer Bros has been freed from Galeem’s control & take it with them as they continue heading through the castle.

2-9: Main Courtyard
The group eventually reach the courtyard & have to defeat several enemies in order to get to Bowser's keep. Bowser, meanwhile, sends someone to take care of them. After defeating all the enemies, the group discovers who Bowser sent to take care of them this time: Mario. Mario tries to jump the Lakitu, but misses & tries to the shell of a defeated Koopa Troopa at them before the fight begins. Mario then collapses as the aura disappears & Peach rushes forward to see he's okay. She hugs him, thinking he's dead & kisses her forehead & Mario then wakes up & hugs back as he then joins the group & everyone heads to Bowser's Keep to rescue Bowser.

2-10: Bowser's Keep
The group reach him on a bridge that has an axe on 1 side as he, mad that they got him too, attacks them with Bowser Jr. horrified that he doesn’t recognize him, but determined to have him come to his senses. Bowser then collapses & as Mario, Peach, Bowser Jr., Piranha Plant, the Lakitu & the Hammer Bro approach him, a drill made of wings emerges from the top of the castle & destroys the bridge, causing all of them to fall to a lower part of the castle with Bowser falling into the lava. The group recover to see Galeem who then forms its 2 wings into a hand & sprinkles some black paint on where Bowser was before leaving. Everyone then turns to Bowser reemerge as Fury Bowser as the sky turns dark red, which Galeem starts consuming while everyone takes on Fury Bowser. Fury Bowser then flies into the background & starts heaving black paint as he shrinks & turns back into Bowser. Bowser then recover & gets hugged by Bowser Jr., the Lakitu, the Hammer Bro & the Chain-Chomp. He then sees Mario, Luigi & Peach with them, feeling a bit embarrassed that they saved him & then joins them. Galeem, mad that Fury Bowser was defeated, swats everyone into the sky with 1 of its wings. It then releases several more light orbs everywhere & leaves to continue its investigation of the missing spirits & characters. Meanwhile, where Galeem was at before investigation, Master Core, who Galeem has wrapped in an orb of light, starts to light a bit as it shows a spirit inside of it.

3-1: Homecoming Hijinks
The group regain consciousness as they noticed they’re in the snow & Mario realizes that they’re at Donkey Kong Island. However, he & the others are rather puzzled as to why there’s snow here. The Piranha Plant then finds a banana, which gives Mario the idea to find & rescue Donkey Kong & whoever could be here. After reaching the end of the level, the group notices several trees getting knocked down on their left & jump out of the way as Rambi charges forward. Rambi then collapses as the Chain-Chomp carries him until the group noticed that some Light Clones are guarding the pathway to the beach. Rambi leads, having recovered, the group towards it as he plows through several Light Clones as Peach hangs on, while Mario & Luigi ride on Yoshi & the Miis hold onto the Chain-Chomp.

3-2: Seashore War
After reaching the end of the level, the Chain-Chomp is dragged into a puddle that emerged. The group then notices that there's several puddles around them & Orcane emerges as he dodges several attacks before lunging at them. The Nerd then finishes Orcane off as he then collapses as the group take him with them since he acted similarly to the Piranha Plant, the Lakitu, the Hammer Bro, the Chain-Chomp, Rambi & Goose. He then wakes up to see the group sleeping, settling down due to the cold since Mario made the fire using barks from the palm trees & his pyrokinesis & decides to guard them since he already got his rest. The group then wakes up as Orcane puts out the fire & seeing the ship on top of the volcano, think they need to take care of whoever in there to get rid of the snow as they head to the ruins.

3-3: Aqueduct Assault
After reaching the end of the level, the Hammer Bro & Lakitu notice a Klaptrap that survived & it's not attacking them. It skitters towards them, which the rest noticed as they were looking something peculiar on 1 of the walls, showing a mysterious being that appears in people’s dreams. Thus, everyone decides that they need more information on it before they decide to start looking for it.

3-4: Blurry Flurry
The group discover that they need to get through the cave in order to continue the path towards the volcano. After reaching the end of the level, they notice someone has been slamming snowballs & causing stalactites to fall throughout their trek & discover that it was Magnus who then attacks them. Magnus then collapses as the cave starts collapsing. The Chain-Chomp, Yoshi & Orcane carry him out as the others escape. After escaping the cave, Magnus wakes up, thanks everyone for saving him & joins them as they head to the forest.

3-5: Forest Folly
After reaching the end of the level & dodging giant snowflakes, the Smash Bros. hear not 1, but 2 beings swinging around the trees & sees that it's Donkey Kong & Diddy Kong who enter a launch barrel held by a Master Hand who then fires them at the group. Mario steps forth due to having fought him before, but the others join him as they don’t want him to be outnumbered by them. Diddy Kong collapses while Donkey Kong rolls around before landing on top of him. Before the group can check on them, the Master Hand from earlier swoops in to stop them. The Master Hand explodes as Diddy recovers & manages to get himself off out of Donkey. Donkey then follows suit & then he & Diddy both thank everyone for saving them, though the Nerd is at a loss of words seeing them in person & Peach had to defend the Klaptrap from them when they notice it with them. Donkey & Diddy then lead everyone towards the volcano, knowing why they’re here.

3-6: Cliffside Slide
The group arrive at the cliff as they realize that they have to also go through the factory that’s near the top of the cliff. However, they feel a lot of shaking & notice that several enemies slamming against it, causing an avalanche of rocks, bones & snow, though they’re determined to trek up it since they need to get to the ship. After reaching the end of the level, the group is then attacked by a Burrowing Snagret that emerges from the ground. The Burrowing Snagret then collapses & the group pulls it out of the snow as the avalanche continues & as they head to the factory to rest for a bit. It then wakes up & alongside the Dark Emperor, guarded everyone as they rested inside the factory.

3-7: Frozen Frenzy
Everyone enters the factory as they break the ice surrounding the power system to reactivate, despite part of the building missing several bricks & then rest for a bit. Meanwhile, Lord Fredrik discovers the group have reached the island & are almost close to him after seeing the factory working again. He then sends more enemies & Light Clones as well as 2 particular beings towards the factory and the volcano with 1 grabbing a straw hat. The Smash Bros. then wake up & notice that several enemies are now in the factory & thus have to continue their trek to the ship. After reaching the end of the level, Donkey & Diddy Kong sense someone rather familiar to them, lurking in the factory. King K. Rool then jumps at them & the 3 clash as everyone soon joins the Kongs. K. Rool then collapses & Donkey Kong, remembering what he did to temporarily save him from Galeem, carries him over his shoulder out of the factory as the rest of the group finally reaches the volcano, thinking that the heat from the lava will speed up his recovery & have to get to the other side of it in order to reach the ship where Fredrik is at.

3-8: Meltdown Mayhem
Like at the factory, everyone starts breaking the ice as the lava emerges from walls & even the floor itself. As the lava flows inside, K. Rool wakes up as everyone finally warms up & joins them as they have to reach Fredrik’s ship before the volcano erupts & Galeem notices with Rambi helping them bust through several blocks with his face on them as well as snowballs that create temporary bridges for them. After reaching the end of the level, the Smash Bros. reach Fredrik’s ship, only for a barrel to be tossed at them by a Bonkers before K. Rool takes care of him with a Gut Check. Donkey Kong then inspects the barrel, only to get punched in the face as Luffy emerges from the barrel & begins his fight with everyone. Luffy collapses as the aura disappears & then recovers as he grabs his straw hat, which was slowing landing after his defeat. He then leads everyone inside Fredrik’s ship, knowing why they're here.

3-9: Volcano Dome
The group arrives at Fredrik’s throne room where Fredrik jumps them & destroys the floor, sending everyone to a basalt field in a pool of lava, initiating the fight. Fredrik collapses & at that point, the volcano erupts, launching the ship & everyone on it upward into the water as the snow melts away. Galeem hears the volcano erupt & heads over to check. Everyone that’s still on the ship start rescue everyone that fell into the water with Fredrik grabbing Luffy since he can’t swim. He, Donkey Kong, Diddy Kong & K. Rool glare at each other before they notice a light coming towards them & gets everyone to start manning his ship to escape. Galeem notices that both the snow & the ship are gone & the factory is up & running, thinking the Smash Bros. survived the flinging & broke the control of more of its minions. It then sees water currents that are moving away from the island, prompting it to follow them.

4-1: Octo Canyon
Fredrik’s ship washes ashore to Cephalon HQ & breaks into pieces. Everyone notices that they've arrived at Octo Canyon & thinking that they're probably here, start looking for the Inklings & Octolings. After reaching the end of the level, the group is gets attacked by Klonoa who looks more snarly & charges forward at them. Klonoa then collapses as the aura goes away & then recovers & rubs his head, thinking that he went through some bad dream journey. He then joins the group as they continue going through the Cephalon HQ.

4-2: Octarian Stadium
Everyone eventually reach the Octarian Stadium & have to fight several enemies in order to continue on. After defeating everyone, a Octosniper throws a Pokéball that releases a Toxtricity as Pikachu charges forward while Klonoa releases Eevee & Luffy releases Meowth. Toxtricity collapses as the Octosniper returns to its Pokéball, only to be defeated by Klonoa & he grabs the ball before rejoining everyone else as the coliseum collapses.

4-3: Underground Expressway
The group then heads into the Underground Expressway to continue their search, while dealing with not just enemies, but also Dash Tracks, Ride Rails & even invisible platforms that can be revealed with ink, using nearby Ink Bombs or ink from Octosnipers & Octolings. After reaching the end of the level, Penny is stuck in gum, which everyone else finds weird. They then get stuck in gum themselves as Berecca reveals herself. Mario & Bowser burn the gum off them, while Fredrik freezes it off him before they free the rest. However, they notice that someone is drawing something over them such as tomatoes, birds & cats, obscuring their views & Fredrik then points towards 1 tower that shows Vince just painting, trying to help her before the fight begins. Berecca slams into a wall while getting stuck in her own gum before passing out herself, while Dave slams Vince’s canvas over his head & then he passes out before he gives a sheepish grin & puts his fingers together, thinking that he might’ve overdid it. As everyone approaches her, they realized that she’s not an Inkling nor an Octoling, since she used gum instead of ink to fight. Vince, who also recovered, then paints a picture of the Inklings & Octolings & shows it to her to see if she’s seen them. She nods & leads everyone where she thinks she saw them.

4-4: The Octogalaxy
Everyone reaches the Octogalaxy, dealing with the same obstacles as well as Ink Pistons, Balloon Fish, Inkfurlers, Ink Cannons & Gushers. After reaching the end of the level, the Smash Bros. notice ink everywhere, finally getting a lead as to where the Inkling & Octoling could be, only to get surprised by a Splat Bomb as well as 2 Ink Shots. Berecca points to show that Marie & Marina are sniping at them, while the Inkling & Octoling hand some spirits to a Master Hand to send to DJ Octavio before they charge forward as he escapes. The Inkling & Octoling collapse while Marie & Marina fall from their vantage points as their souls leave, which the Master Hand then grab & put in jars before charging towards the group to deal with them. The Master Hand explodes as Mario, Luffy, Klonoa & Berecca open the jars, grab the souls & place them back into their bodies, causing them to wake up & after thanking everyone, joins them in stopping Octavio from telling Galeem that he’s found them.

4-5: Transfer Junction
Everyone reaches Transfer Junction where they discover that Octavio is in Alterna, having watched them throughout their journey since the Underground Expressway, so he could tell Galeem where the Smash Bros. are at & go through enemies, Sponges & Splat-Switches. After reaching the end of the level, everyone notices something rather particular on the ground: 2 leeks. As Marie picks them up, Octavio drops Hatsune Miku off & points towards the Smash Bros. as she sees that they’re touching them before leaving. She comes at them with a jump kick as everyone else notices her & fights through Olimar, Yoshi, Birdo & the Hammer Bro to get to Marie. She whip kicks her forward, knocking her against a wall as she lets go of the leeks & grabs both in her right arm before whacking them at Mario & Luigi before the fight begins. Miku collapses as Galeem’s aura dissipates, while Marie & Marina exam her as they’re surprised to learn that idols existed longer than they thought, given how she was dressed. She then wakes up & rubs her head as Berecca shows that where she’s from there are outfits that are replicas of her outfit, demonstrating that others have heard of her, exciting her. However, she realizes that if Galeem won, she’ll be wiped out of existence alongside everyone else & joins the Smash Bros. to stop it.

4-6: Paradise Lanes
Everyone arrives at Paradise Lanes as it’s the last place to get through before reaching Alterna while dealing with enemies, Balloon Fish, Ink Switches & Gushers. After reaching the end of the level, they notice that there aren’t any enemies here, so they look after, only to be either webbed to a wall like the Thwomp & Miku, webbed together with someone they were with such as Mario, Luigi, Bowser & Fredrik as they were thrown together after getting, stuck on the floor like the Lakitu or left hanging on a high platform like Captain Toad & Dave. The Mii Fighters & Berecca discover them like this, only to get webbed themselves where they & the rest discover that it’s Spider-Man who slides down on 1 of his webs, having been sent by Octavio after Miku failed & switches between hitting everyone. They all struggle & break free from his webs & try to fight him, only for his Spider-Sense to activate, allowing him to dodge attacks & trick each other into hitting each other before the level begins. Peter crashes into a structure, knocking him out cold as it collapses on top of him & Galeem’s control wears off. Everyone else comes to get the rubble off him while he sees Aunt May & Uncle Ben’s spirits coming to him inside his head to keep him motivated. He then pushes himself up & lifts the remaining rubble off his back. Mario uses sign language to ask what motivated Peter into not giving up, despite their help. Peter webs over a picture of May & Ben to them to look at as he lost them before this all happened & see him hang his head low & then joins the Smash Bros..

4-7: Alterna
Everyone then reaches Alterna as Peter webs a bridge for them, which he does the OK sign with how stable the bridge is before swinging forward & pulling out another bridge to help them as he scouts ahead as they have to reach Octavio before he tells Galeem that he found him. After reaching the end of the level, everyone notices several spirits being fed into the Octobot King as it powers. It then moves to show Octavio who stares at the Smash Bros. & placing a security key to keep his theme playing without worry of it being hacked like what the last 3 times before beginning the onslaught on them to keep them busy until Galeem gets the signal or if that doesn’t work, kill everyone himself. The Octobot King explodes as ink flies everywhere & Octavio is sent flying towards the Smash Bros., crashes into a pile of snow & passes out as the antenna he was using to contact Galeem short-circuits, as the spirits are freed & everyone start collecting them. The Inkling then pulls something she had with her: a snow globe, which everyone else, except Marie, finds weird, though the Octoling gives an interested look upon seeing that this is what her former master was trapped into. The Inkling then gives it to her, so she could keep an eye on her once he was recovered as everyone else leaves Alterna. Meanwhile, the apparitions of May & Ben return to Master Core as the spirit from within sent them to help Spider-Man as if it’s helping the Smash Bros. stop Galeem.

5-1: Building Lobby
The Smash Bros. arrive another city, which, after seeing an advertisement for the Mintendo Noodle House, know that they could be find Min Min here, but have to enter the Sky Arena in order to find her. They head off the building's lobby where several enemies & Light Clones attack them upon seeing them. After defeating every enemy, the elevator opens as Little Mac & Sukapon leave & begin the fight. Little Mac collapses & Sukapon falls to pieces as Galeem's aura dissipates. The Octoling picks up Sukapon's piece as she, the Inkling, Yoshi, Bowser Jr., Mii Brawler, Mii Swordfighter, Mii Gunner, Marie, Marina & Berecca use the elevator, while the rest take the stairs as Bowser carries Little Mac.

5-2: Sky Arena Building 15th Floor-20th Floor
As everyone starts climbing the floors, they eventually regroup on the 15th floor as they need a key to get to the Laboratory where they could find info on that being they saw in the ruins back in Donkey Kong Island with everyone rescued afterwards getting caught up after a paper on it in 1 of the desks. Sukapon then recovers & attacks 2 Rocket Grunts & throws a Fire Walking Piranha Plant into a wall, while Little Mac, who also recovered, punches 5 more Rocket Grunts as more enemies flood the stairs. After defeating everyone, they discover that the key isn't on this floor. Then the elevator dings again as Tails leaves & Spin Dashes forward towards the group & commences a fight. Tails collapses as Galeem's aura disappears & Little Mac grabs him as everyone else head to the 16th Floor to continue their search for the key. As everyone checks the 16h Floor for the key, the elevator opens again & a Toaster ARM emerges as Spring Man leaves & punches several of them while parrying others' attacks as before the fight begins. Spring Man then collapses as Galeem’s aura dissipates & his ARMS disappear. He then recovers as Berecca helps him & points out that they have the same pompadour, which Berecca humors him by poking his. He then leads everyone that's taking the stairs to head to the 17th floor as they take care of more enemies. After defeat everyone, the elevator opens again with Little Mac standing by it & sees Shantae jump over him as she fights the Inkling & Octoling before the rest join in. Shantae collapses as the aura disappears & then more enemies show up, but are defeated as she recovers & helps them take care of them as she showcases her hair-whipping & transformation abilities. This being enough to convince to take her with them as she’s just determined as them to know why this even happened as they head up to the 18th Floor where they get greeted by Bald Bull with him charging at the group, though Fredrik was able to freeze for a bit before Little Mac uppercuts him. Bald Bull stumbles a bit, does a spin & falls facefirst as Galeem's aura wears off. After the group still has no luck with finding the key, he then gets up where he begrudgingly puts his hand on Mac to thank him for rescuing him as he joins the group & the group continues onto the 19th Floor where, at this point, everyone expected to not find the key on that floor. After defeating everyone, the elevator opens again, which Ryu Hayabusa dashes out as he clashes with Berecca before the rest join in. Hayabusa is thrown against a wall & passes out with Shantae picking him up as the group head up to the 20th Floor, which is where the key would most definitely be at, since they've checked the other floors. After they reached the 20th Floor, the stairway & elevator flood with 60 Fall Guys, holding some of them as 1 snatches the key from Spring Man & runs off to keep it away from the group. All the Fall Guys then collapses after they're all defeated & the one who had the key was thrown back into the room, thus the group now finally has the key to ARMS Laboratories, which is a few floors above them as they head & the Fall Guys, having recovered, soon follow them as they don't want to be left behind.

5-3: ARMS Laboratories
Everyone finally enters the ARMS Laboratories as they learn more about how Spring Man & Min Min's ARMS work, despite still not having found the latter as the Fall Guys help everyone get things done quicker until several enemies arrive due to the intrusion. After defeating everyone, a Master Hand punches through the building to drop off something before leaving, which turns to be SpongeBob SquarePants, surprising everyone, who then growls like a rabid dog & laughs maniacally before running towards them. SpongeBob collapses as the Master Hand returns & grinds against him everywhere for failing to stop everyone until the group intervenes. The Hand as SpongeBob recovers & everyone else realizes that there's no stairway to the main arena, so they decide to use the nearby rooftops around the building to reach it with some holding onto SpongeBob as he inflates himself towards 1 of them & the Fall Guys making a bridge of themselves to cross before pulling each other up.

5-4: City Rooftops
After reaching the end of the level, Spring Man notices something jumping from roof to roof coming at them. An oddly-colored chicken who attacks him & the rest with wrestling moves, dodges as it reveals the chicken is Juan Aguacate as he switches between both forms. Juan then collapses with Spring Man wondering why he’s wearing a Luchador if he doesn’t have ARMS like him & Min Min. He recovers as Spring Man grabs his arm & joins everyone else as they head to the main arena.

5-5: Main Arena
Everyone finally reaches the main arena as the sun starts to set while Galeem absorbs more darkness from it & deal more enemies in order to win the tournament. After defeating everyone, the group finds out that Min Min is the champion of the arena & attacks them as she approaches the ring. Min Min stumbles as she notices that Dr. Coyle emerges from her right & punches her as they come to blows as Spring Man also joins in until she teleports behind Min Min & uppercuts off the arena. This causes Spider-Man to jump down to save her with his webs which he does, though Min Min grabs onto him 1 arm since he fired webs from both wrists & grabs the railing with the other as the 2 reenter the battle. Hedlok explodes into pieces as Dr. Coyle collapses to the ground as Galeem’s aura fades. Spring Man & Min Min both then approach her as she recovers, turning their ARMS back to normal. Coyle’s ARMS turn back to normal as she shakes hand with them with a disgusted look on her, since she knows why they & the rest rescue her. She then heads to her lab where she grabs the blueprints for Hedlok, so she could rebuilt him to help the Smash Bros. deal with Galeem, while Min Min discovers a poster for the F-Zero Grand Prix. This causes him to enter the racing tournament to rescue Captain Falcon & whoever else could be there.

6-1: Mute City
Everyone arrives at Mute City & decided that they have to enter the Grand Prix, since that’s where the first of 5 races will take place at, but most of them don’t have vehicles. So, they decide that they should just get of all the cars, since the poster doesn’t have any rules on them, which they do find rather peculiar. The race then begins as they each get some of the cars competing while Flies & Hand flies near them & Octavio, who has recovered at this point, being placed inside the car that the Inkling, Octoling, Marie & Marina start on, though several enemies notice what they’re doing. After reaching the end of the level & the 2nd lap of the Mute City race, they notice that some cars are being knocked towards them & find out that it's Dillon that's doing it. Dillon collapses & hits 1 of the cars behind him as Spider-Man grabs him with his webs, since he doesn't want to wait for the next lap to save him, which everyone agrees to & continue to reach the front of the race. After reaching the end of the level, Mario & Luigi notice some people rather familiar speeding towards them: Wario on his bike & Waluigi on his kart. They then see them & snarl at them before lunging at them as the bike & kart veer off course & explode. Wario & Waluigi stumbles off the back of the car as Galeem’s aura fades, but Luigi grabs him before his head hits the bumper. The car that they, Mario & Peach are hanging onto wins the race, much to Waluigi's delight, thus willing to work with Luigi & the others.

6-2: Big Blue
The Smash Bros. arrive at Big Blue for the 2nd race of the Grand Prix with Wario & Waluigi knowing what to do since they saw the others do the same before they got to them. After reaching the end of the level & the final lap of the Big Blue race, Wario & Waluigi narrowly dodge an X-Slash that destroys the car they were on, getting everyone's attention as they also dodge the slashes, which Wario realizes are coming from Kat & Ana. Wario grabs Kat, while Waluigi grabs Ana & they slam them together, causing them to pass out as Galeem's aura fades & the group wins the 2nd race. Kat & Ana then recover & both hug Wario for saving them, apologizing for trying to kill him & the others.

6-3: Red Canyon
Everyone arrives at where the 3rd race will be at: Red Canyon where they know all the drill by now: win the race & find Captain Falcon. As they go through the race, they realize that they have to deal with falling boulders. After reaching the end of the level and the 3rd lap of the Red Canyon, they notice 1 vehicle coming at them that they sort of recognize: the Fire Stingray, driven by Samurai Goroh. He puts the Fire Stingray on autopilot as he opens the cockpit window, jumps to where the Smash Bros. are & pulls out his katana. Samurai Goroh collapses as Galeem’s aura fades & Marie & Marina get on the Fire Stingray as they turn off the autopilot, so they could move to the right spot, so the rest could put Goroh back in before putting it back on, so nothing bad would happen to him, since he might know where Captain Falcon is, since he’s his rival. After reaching the end of the level & the final lap of the race, Goroh recovers & notices 1 of the vehicles coming at him, which the rest do too. They then notice that a Master Hand saw that they entered themselves in the Prix & is now trying to stop them from winning this race. The Hand explodes as everyone wins the race & Goroh leads them to where the next race will be at.

6-4: Fire Field
It’s revealed that Galeem is watching the Prix where the former discovers the Smash Bros. entered & crush its screens in frustration as it heads off to deal with them while Dharkon, who’s watching Galeem, does a laughing gesture at its misery. Meanwhile, everyone enters the Fire Field, several of them having to stretch their clothes due to the heat, though the Ring Fit Trainee isn’t bothered by it. Goroh reveals that the Fire Stingray & other vehicles having air conditioning inside them, so some of them could be with him as the rest could just hijack some of the other vehicles, though they have to be careful since the course doesn’t have any guardrails. After reaching the end of the level & the 4th lap of the Fire Field race, Goroh notices a laser on 1 of the vehicles in front of him, which gets shot by a bullet & crashes. Everyone tries to find the source of the bullets & eventually find that the laser is coming from a bus that seems to be flying & is also on autopilot, revealing that Jonesy is the one that’s been shooting at them. Everyone then reaches Jonesy while dodging more bullets as well as the parts of the tracks that make the vehicles upside down. Jonesy collapses as Galeem’s aura fades & falls off his bus. He then teleports back on it using his Rift-To-Go back to normal as the rest that left the vehicles can now get back on them after the track goes back to normal for the time being & win the penultimate race as they head to the final race since they know that it's where Captain Falcon lives.

6-5: Port Town Aero Dive
The group arrives to Port Town Aero Dive where the final race will take place where they know for certain that they're going to find Captain Falcon here. Little did they know, Galeem also arrives to drop someone off as it can take care of the Smash Bros. while it goes absorbs the light from the trade center as the race begins. After reaching the end of the level & the final lap of the race, Goroh sees the Blue Falcon boosting towards him as Captain Falcon ejects from it as he places it on autopilot & tries to Falcon Punch the Fire Stingray, but Goroh gets out of the way. Everyone then moves their vehicles together, so they could stay together as they fight him. Captain Falcon is flung back into the Blue Falcon, causing him to turn off the autopilot & veer off the side of the track with Jonesy using a Rift-To-Go to transport the Battle Bus to rescue him while Fredrik dives to grab the Blue Falcon & throws it back on the track as he & Jonesy teleport themselves back on the track. As they go through the race, they notice several vehicles getting tossed from behind, which several of them realize that it’s Duon, thinking that Galeem dropped him off as a last ditch attempt to get them to forfeit the Prix as more enemies start swarming them. After reaching the end of the level & winning the race, the Smash Bros. get attacked by Duon as he’s not being a sore loser since he was dropped off to take care of them & not to win the Prix. Duon then collapses on his side as Galeem's aura fades away, but manages to reactivate by himself as he notices several enemies trying to close in on the group. Duon then follows them behind Penny, the Blue Falcon, the Fire Stingray & Flies & Hand as they go through another wormhole after they're all token care of.

The Smash Bros. arrive at Station Square.

7-2: Casinopolis
The group arrives at Casinopolis where they think that they could find Sonic here with dealing more enemies & pinball machines that could drop them into a garbage dump underneath it containing spike balls & a giant fan. After reaching the end of the level, the group is blindsided with a sudden emerge of buildings that starts from moving from member to member. They find out that Dr. Wright is commanding the pile of buildings & have to reach him to get him to stop & free him. The Nerd knocks out Wright, causing the buildings to disappear. He then recovers & apologizes for trying to kill them & joins their search to find Sonic. After reaching the end of the level, they got spotted by Ed, Edd/Double D & Eddy. Eddy sends Ed & Double D after the group with the former tossing slot machines at them, while the latter tries to punch Tails as Eddy puts several coins into his pockets. Ed grabs & tosses Mario & Luigi into another one before the next fight begins. The Eds are sent flying through the air & collapse on top of each other as Galeem's aura fades from all 3.

Meanwhile, Eddy encounters Cartman as he attacks him while those who were too far to help Tails deal with Amy. Cartman collapses as Eddy does the same thing Tails did with Amy. A bit later, Amy & Cartman recover as Master Hand arrives to look for them, but attacks everyone upon seeing the 2 no longer under Galeem's control. The Hand explodes as everyone then leaves the Park as they continue their journey of finding Sonic with Chaos watching them again, rubbing his head since Ed drank from him & conjuring a water orb to show Galeem what happened before Galeem points to its side as to tell him to follow them.

7-4: Speed Highway
Everyone arrives at Speed Highway where they find Sonic, but he gets away, causing them to chase after with Pikachu leading them as it remembers how he tried to save it & some riding on Duon. After reaching the end of the level, everyone hears whirring as several Excitebikers start rushing towards & surrounding them, thinking that Sonic sicced them after them. All the Excitebikers then crash into each other as they get wrecked, but survive as Galeem's aura fades from them & help the group try to catch up with Sonic. After reaching the end of the level, the group finally catches up to Sonic as Pikachu, Tails & Amy try to snap him out of it, but have to knock some sense back into him. Sonic then collapses as Pikachu, Tails & Amy run up to see if he's okay & Pikachu then nudges him to wake up as it tears up. He then does & hugs Pikachu as he gets teary-eyed before Tails & Amy come in to join them before they continue on the next area since Sonic knows that Knuckles & Chaos could be around here too.

7-5: Mystic Ruins
The group then reaches the Mystic Ruins where they rest for a bit before they try to find Knuckles. Tails then starts fixing up Duon for any minor injuries he got from the battles. Chaos then materializes as he moves in to attack him while he’s distracted, but Tails notices & fights him with Duon helping before realizing that he was distracting him, so more enemies would arrive to attack the others before jumping into the water to retreat. After reaching the end of the level, everyone notices several rockets coming at them, which Ness knows where they could be coming from. He then sees Jeff Andonuts setting up more rockets before firing them off & thus, have to reach him to get him to stop. After reaching Jeff, some rockets end up hitting him, knocking into a wall. Ness & Lucas runs over to check up on him as he comes to since Galeem's aura fades. Jeff then hugs Ness, thanking him for saving him & joins the group as they continue through the ruins. After reaching the end of the level, Sonic & Tails see someone gliding towards them, knowing who it is. It turns to be Knuckles who slams into the ground as everyone backs off. Chaos appears to show that he sent him to take care of them while he takes the Chaos Emeralds with him, since they're in the same area as the Master Emerald. Sonic tries to spin dashes into Knuckles, but Knuckles grabs him with 1 hand & slams him into the ground. Knuckles collapses as Galeem's aura fades, but then recovers as he sees that, while Chaos stole the Chaos Emeralds, the Master Emerald is still there, but in pieces, enraging Knuckles, since Galeem smashed it while he was fighting the group.

After reaching the end of the level, everyone starts getting shot at, which they see is coming from C.J. & several Light Clones of Bill, Lance, Marco, Cuphead, Mugman, Doom Slayer & Gunvolt, which they decide to deal with before they turn their attention back to Chaos.

He then recovers & joins the group of how they reminded him of the Grove Street Families due to him seeing them help & be there for each other ever since this happened as they continue through the flooded city. After reaching the end of the level, everyone reaches Chaos who absorbs the energy from the Chaos Emeralds & tosses them to them where Tails & Spider-Man analyze them & realize that there's no energy readings inside of them. This makes everyone realize that Galeem must've made Chaos able to absorb all energy from them instead of just the negative energy as he grabs & throws them into the water before the battle begins. Perfect Chaos begins to deform & sink, roaring wildly as Galeem’s aura fades away from him & turns back into Chaos-0. He then returns the energy to the Chaos Emeralds, since Galeem also gave it the ability to become Perfect Chaos without them, though he directs his anger towards Galeem for having used him as a roadblock to the Smash Bros. & joins the group. He then gets inside Penny as another wormhole emerges & everyone goes through it.
