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.

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.
 * Unlockable Assists become available in the Defeat All The Enemies Levels.
 * You can bring more than 1 characters into boss fights with the health bars expanded to compensate.
 * Any Assist Trophies that are playable in Assist Smash can help during boss fights.
 * Stocks are removed, so the difficulty could be based around the level design & challenges.

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 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 he 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.
