Adventure Mode: The Subspace Emissary

Adventure Mode: The Subspace Emissary is a mode in Super Smash Bros. Brawl, similar to Melee's Adventure Mode. It is also called Story Mode. It was hinted at with the This world... Dojo update on July 20th, and fully unveiled on August 3rd.

Overview
On July 20th, Smash Bros. Dojo!! was updated with a collection of enigmatic images that depicted Mario and Kirby transforming from trophies into fighters (akin to the introduction of Melee). After Kirby’s apparent defeat at the hands of Mario (or vice versa, depending on which character the player has chosen), he is changed back into a trophy, but Mario reverses the transformation and Mario and Kirby shake hands. However, the sky darkens soon after, and Meta Knight’s ship, the Halberd, flies over the stadium, soon followed by the appearance of a mysterious character. The screen shots were accompanied with this description:

''In this world, trophies fight. They know nothing but fighting. Fighting is the sole reason for their existence. Being turned back into a trophy, being unable to fight, is much like death. Those are the rules of this world. But...When someone...or something...breaks those rules, the world will pay a terrible price...''

The post was placed under a mode referred to as “???” until August 3rd, when it was changed to "Adventure Mode." On August 3rd, Smash Bros. Dojo!! was updated again. This time, more information was given. The mode was dubbed “The Subspace Emissary,” and a multitude of screenshots were shown, as well as a cutscene related to the “This World…” update. In the cutscene, Mario and Kirby were seen shaking hands, as depicted in the screenshots, and after waving to the crowd, the Halberd appeared as it did in “This World…” The mysterious character from before was shown to be one of apparently many odd, robot-like creatures formed from some sort of shadowy matter. Princess Peach and Princess Zelda were seen watching from the sidelines, but rushed down to the middle of the stadium to assist Mario and Kirby in fighting the mysterious army. After Peach and Zelda reach the stage and help destroy the Primids, an entity from the sky called The Ancient Minister appears on the stage. The Ancient Minister drops a Subspace Bomb on the arena, then flies off. As Mario approaches the bomb, he is hit by a cannonball and is sent flying from the arena. Petey Piranha appears and captures Peach and Zelda in cages. Some fans believe that Mario "broke the rules" of the World by reviving Kirby, and this is what triggered the Halberd to arrive and deploy its drones. Interestingly enough, the use of bosses in this mode was very vaguely hinted already in the first update. When the Battleship Halberd is seen flying out of subspace, purple skies are covering the sky. In the skies, you can clearly see the faces of Bowser and Rayquaza, as well as blurred faces resembling Ganondorf and possibly Porky Minch. Ridley is also reported to be seen.

The various screen shots in the update depicted a multitude of new enemies, as well as a few familiar ones, such as a Hammer Bro, who was previously confirmed as an Assist Trophy, and Bullet Bills. There were also a new series of enemies that were introduced that are part of the Subspace army. Some enemies of the Subspace army appear to be helpful while other ones are dangerous.

Game play
The Subspace Emissary mode is a side-scrolling adventure in the style of a platformer, inspired by the Mario and Kirby games. However, it retains all basic mechanics of Super Smash Bros., such as a damage meter, stocks and Smash-style attacks.

The mode features a world map where stages are selected; once a stage is selected, the difficulty can be chosen, and the character(s) will enter the stage. The selectable characters will change depending on the plot. Also introduced on Oct. 5, 2007 you can play with two players but it is optional.

When playing a level for the first time, many cutscenes will pause just before gameplay begins, showing a view of all available characters. A message will tell how many characters can be chosen for the level, and a cursor will appear that will let you choose which characters to play. The order characters are chosen in is the order they will appear: they will cycle through in that order until all stock is depleted. Playing through a level again, there will be a screen before the level allowing you to choose between any available characters instead of cutscenes during the level. This can be both an advantage and a disadvantage: you have a wider character variety to choose from, but you must choose the full number of characters. On a six-stock stage, you must select six different characters. You can't just select four characters and have extra stock that will cycle through them as you could in many levels the first time. Additionally, no mid-level cutscenes will play, including ones that would normally allow you to choose new characters and replenish stocks. While on many levels this makes little difference, it is very problematic on long stages like the second Subspace Bomb Factory, where you have to beat the level with a fraction of the lives you would normally get playing through.

Also, some of the character's stats are changed in side-scrolling stages. The characters jumping height, running speed and falling speed are altered. The difference varies from character to character.(i.e.; Pokemon Trainer's Pokemon will not be affected by stamina)

Plot
Notes: Because it is possible to take more than one path in Adventure Mode, there are sometimes two characters' names, divided by slashes when describing a scenario. (i.e.; Peach/Zelda) This means that if you take the first path, the scenario involves the first character, and vice versa. Also, there is no official chapter-by-chapter layout to the actual mode; the following material is divided in to chapters strictly for the sake of clarity.

Prologue
The following prologue material is culled from information in in-game trophies and the Dojo, and is not depicted in in-game video cinematics.

The Subspace Emissary depicts two realms: The "main realm" of "our world", known as the World of Trophies and is very much a typical Earth-like setting, and the realm of Subspace, a world of darkness. The "master" of the world of Trophies is the entity known as Master Hand; likewise, Tabuu, the main villain of the plot, is the master of Subspace and the effective embodiment of it. Tabuu intends to cut the World of Trophies into pieces and assimilate them into his own world. In preparation for this plot, he has long observed Master Hand and the fighting denizens of the World of Trophies (hereby referred to as "Smashers"), studying the fighting styles and mechanics of the trophy-based characters. Tabuu himself cannot leave Subspace, so his plan is to gather and arrange an army that Master Hand would lead as his proxy.

Tabuu captures and enslaves Master Hand, and bends him to Tabuu's will using chains of light. Very shortly after acquiring Master Hand, Tabuu learns of the Smasher named Mr. Game & Watch, an entity without any concept of good or evil but is comprised of a trans-dimensional "mass" that has strange qualities. An infinite amount of a primordial substance known as Shadow Bugs can be extracted from the Smasher, so Tabuu and his puppet Master Hand capture him for themselves. Using the Shadow Bugs, Tabuu creates much of his Subspace Army, the force which he will have his puppet Master Hand command to invade Master Hand's own world in the plot to bring it into his master's world.

The next phase of Tabuu's preparation for the operation to assimilate the normal world into the world of Subspace centers on the Isle of Ancients, a mysterious landmass that floats in the sky above the World of Trophies. The society within the floating island is filled with advanced technology and is populated by a group of sentient robots classified as R.O.B.s, and they have existed for an indeterminate amount of time without any interaction with the civilizations on the landmass below. The hierarchy of this society is comprised of lesser R.O.B. minions serving one R.O.B. known as the Master Robot with complete loyalty, and they have all lived in peace... up until now.

Tabuu's Master Hand-led forces take the Isle of Ancients hostage, and the Master Robot and its R.O.B. brethren are blackmailed into agreeing to be the main front of the Subspace offensive. The R.O.B.s thus begin to develop and produce the various armaments and utilities to be used by the Subspace Army, including primarily the Subspace Bombs, the timed devices that would explode to engulf a massive portion of the world into a pocket of Subspace and send that part of the World of Trophies into Tabuu's realm. Each bomb would be deployed by the Master Robot himself, and two R.O.B. minions would plug themselves into each bomb to set its countdown timer, which would essentially result in the sacrifices of each R.O.B. unit once that bomb detonates. The Master Robot, out of shame and sorrow for his decision to serve and further Tabuu's scheme for domination and how this is sealing the fates of his brethren, cloaks himself in a disguise and assumes the identity of "the Ancient Minister".

The Subspace Army also takes the plans for the Subspace Bombs and the technology from the Isle of Ancients and begins construction on the Subspace Gunship safely in Tabuu's realm. The Gunship is a colossal airship that can shoot out blasts that fully emulate the effects of a detonated Subspace Bomb; this would be the "ultimate weapon" of the Subspace Army and is Tabuu's intended trump card to complete the operation.

In addition, the R.O.B.s develop personal weapons called Dark Cannons, whose projectiles instantly turn any Smasher into its trophy form, thus emulating an ability Tabuu himself holds within his wings (a deadly assault known as Off Waves); the trophification of the Smashers would be Tabuu's intended measure to deal with any resistance they might mount against his operations. These prized weapons are few in number, though, and can only be expected to be used properly by Subspace Army affiliates that aren't just single-minded grunts; indeed, Smashers themselves would best be able to use them. So to bolster the morale and organization of the Subspace Army, Tabuu has Master Hand seek out and recruit Smashers and other high-profile figures within the World of Trophies that would be willing to serve "Master Hand's" operation to assimilate their world into "his" realm of Subspace. Villainous characters that have had personal conflicts with other Smashers in the past are the ones Master Hand successfully recruit, such as Petey Piranha and Ridley, and the actual Smashers among them are the ones that are given Dark Cannons as the most major members and commanders of the Subspace Army: Ganondorf, Bowser, and Wario.

Ganondorf, a powerful, sinister warlock with aspirations for further power and control, swears allegiance to Master Hand in outward appearances only; his real motive is to usurp power from within and take out Master Hand when the time is right. Bowser, a brutish dragon-turtle-like Smasher with his own little army of grunts and minions, is relatively loyal to Master Hand and likely joins for the sake of settling his long-standing conflict with certain other Smashers, but does not care for Ganondorf. And Wario, a bellicose, obtuse man with a penchant for mischief, cares very little for the actual objective he was given and just wants to continue doing whatever he pleases, but he certainly appreciates having a Dark Cannon with which to turn Smashers into trophies. Of course, none of these three Smasher accomplices to Master Hand are aware of Tabuu.

Tabuu's final act of preparation for his invasion of the World of Trophies is the acquisition of the impressive flying warship named the Halberd, owned and piloted by the masked swordsman smasher Meta Knight, as a primary transportation means for the Subspace Army. So, the Subspace Army launches a violent attack against Meta Knight to take the ship for their own. Meta Knight attempts to defend, but by complete coincidence this attack fatefully coincides with an individual assault on Meta Knight by a rival of his, a self-styled "king" among Smashers named Dedede. Dedede unknowingly makes it impossible for Meta Knight to repel the Subspace Army's attack, so Meta Knight is forced to flee and give up his ship to the Army, and hide out in seclusion elsewhere.

Dedede, in the meantime, during his experience with being caught up in the Subspace Army's attack on the Halberd, comes to know all about Tabuu, his true nature and the potential of his Off Waves trophification ability. After he himself flees from the scene, Dedede begins to worry what will happen once all the Smashers of the world are turned into trophies; after all, if every Smasher in the world is reverted to trophy form, there would be no one left to restore them and each other (since characters in the World of Trophies get turned into trophies when defeated in battle but can immediately be restored at any time by an active character hitting their trophy bases), and the World of Trophies would effectively end by Tabuu's hand. Thus, Dedede gets to work on developing special brooches named Dedede Brooches, which are set to work on a timer; after a certain long period of time has passed, whichever inanimate Smasher trophy the brooch happens to be attached to would restore that Smasher to life. Dedede intends to use these Brooches on himself and some Smashers he may find as trophies down the line, so that there is a chance that he and some other Smashers can cheat themselves out of the doomsday scenario that is likely to happen in the near future, and then have a chance to combat it outright.

Tabuu's operation, in the meantime, has fully assembled all its resources and measures with which to commence the official invasion of the World of Trophies to slice it up and send its pieces back to Tabuu's realm of Subspace. With the Halberd serving as the Subspace Army's frontal flagship and effective "dropship", where it would deposit payloads of Shadow Bugs onto areas where the Subspace Army is needed to facilitate each of the Ancient Minister's bomb deployments, the Subspace Army thus begins its campaign.

Chapter One
The Adventure Mode's focus on the story of the Subspace Emissary begins at a floating stadium named the Midair Stadium, where a competitive Smash match plays out between celebrity Smashers, plumber Mario and infantile pink puffball Kirby. Among the spectating crowds are the princesses Peach and Zelda, Peach of whom is a close acquaintance of Mario. The match ends with one of the two Smashers defeating the other and rendering the other in trophy-state, but shortly afterward the winning Smasher restores his opponent's trophy, and the two shake hands, thus signifying a friendly match well-fought.

It is right here and now that the Subspace Army begins its operation; the sky suddenly darkens and the Halberd appears, depositing a payload of Shadow Bugs into the stadium and forming Subspace Army units. Mario and Kirby are joined by Peach and Zelda and battle this mysterious invading force together. Soon, what they perceive to be the leader of the army, the Ancient Minister, appears and deploys a Subspace Bomb, which is activated by two R.O.B.s, and is set to detonate in 3 minutes. The four Smashers barely have time to investigate the bomb when all of a sudden, major Subspace Army member Petey Piranha appears in the stadium and shoots a cannonball out of his mouth, blasting Mario out of the stadium and far into the sky in trophy form. Petey immediately proceeds to capture the two princesses within his two cages. Kirby must now face the gigantic plant monster and rescue the two hostages.

After Kirby defeats Petey the cages holding the princesses break. Kirby and the one princess he focused on rescuing first, Zelda/Peach, then watch as Wario appears, holding a Dark Cannon. Wario immediately notices the other princess Peach/Zelda in her more helpless position, and he shoots the Dark Cannon at her and turns her into a trophy. He then grabs the trophy and runs out of the stadium, and Kirby and Zelda/Peach begin to pursue him, but Kirby notices that the Subspace Bomb's countdown timer now remains at a mere 5 seconds before detonation. So, Kirby takes Zelda/Peach with him on his personal Warp Star mode of aerial transportation, and they barely escape the Midair Stadium as it is engulfed in a Subspace Explosion that consumes the area and sends it to Subspace.

In a location in the sky far above where the Midair Stadium used to be, Skyworld, young angel knight Pit has been watching the match between Mario and Kirby through his magic fountain, and has been shocked by the subsequent invasion of the Subspace Army and the destruction of the Midair Stadium via the Subspace Bomb. He reports to his goddess, Palutena, who lends him Palutena's Bow and orders him to set out on a journey to combat the Subspace menace. Pit takes his bow and descends into the clouds. Shortly afterward he sees the Halberd approaching and depositing a payload of Shadow Bugs into Skyworld, forcing Pit to begin his fight. Pit then comes across Mario's trophy, which has landed in Skyworld since being blasted out of the Midair Stadium. Pit revives Mario, and the two very quickly agree to team up to fight the Subspace Army and pursue the Halberd. The two heroes aren't quite fast enough to reach the battleship, though, but then they witnesses a smaller attack ship called an Arwing chasing the Halberd.

At this time, Kirby and Zelda/Peach have traveled on Kirby's Warp Star in search of the Halberd themselves. They soon catch up to the battleship and land on its exterior portion, but they don't have adequate time to search around it because the Arwing currently engaging the Halberd is struck down by the Halberd's Combo Cannon weapon, and the Arwing barely collides with Kirby and Zelda/Peach as it falls to the jungle below. The wind from the near-collision makes Kirby and Zelda/Peach fall off the Halberd. The two currently have no choice now but to make their way back down from the Sea of Clouds around Skyworld onto solid ground.

Chapter Two
The Subspace Emissary turns its attention to a region of jungle which is the domain of the gorilla Smasher Donkey Kong and his monkey Smasher nephew Diddy Kong. Their hoard of bananas is being stolen by the minions of Bowser's personal army of Goombas, Koopa Troopas, Hammer Bros., and the like, and the two simians fight their way in pursuit of their property. They eventually find their stash of bananas, but it turns out that luring the two out here was the plan of Bowser, who appears and takes the opportunity to shoot the Dark Cannon at Diddy. Donkey Kong, in a split-second decision, pushes Diddy out of the way and gets hit and turned into a trophy himself. Bowser takes possession of his prize while an intimidated but safe Diddy flees.

As this is happening, Mario and Pit continue their journey in search of the Halberd and/or the Ancient Minister, and touch down on the ground of a large plain. The two find the Ancient Minister again, who is carrying another Subspace Bomb, and they pursue him valiantly but still miss in their attempts to hit him.

Diddy swings his way through more of the jungle away from where he was saved from Bowser by Donkey Kong, and soon arrives at a lake. Diddy then sees the smoking wreck of an Arwing (the one that was downed by the Halberd earlier) that has crashed-landed near the lake. Before Diddy has a chance to investigate, however, out of the lake emerges an immense, serpentine beast, the legendary Pokémon Rayquaza, who blasts the wrecked Arwing and grabs Diddy in anger for their invading its territory. In the nick of time, the pilot of the Arwing, Fox, jumps out of the burning wreckage and saves Diddy, and the two Smashers team up and defeat Rayquaza together.

Fox is about to head off on his own when he is stopped by Diddy, who tries to enlist Fox's help in searching for Bowser and try to get back Donkey Kong, and Diddy soon has to resort to literally dragging Fox behind him by his collar. Fox and Diddy then travel together and battle their way through more of Bowser's troops, and soon encounter a clone of Bowser comprised of Shadow Bugs, which they defeat in battle. The real Bowser shows up again and fires another shot from his Dark Cannon at them; through quick thinking and reflexes, Fox grabs Diddy and jumps off a cliff to save them both.

Chapter Three
The story shifts its attention to a location elsewhere in the World of Trophies that is essentially a deserted, dilapidated zoo, and focuses on a young, timid boy named Lucas who has psychic powers. As he wanders around the zoo, he is suddenly attacked by a colossal, animatronic statue referred to as the Porky Statue. Lucas tries to run from the statue, but is about to be doomed when another psychic kid, Ness, heroically appears and shatters the statue with his PK Flash. The statue reveals itself to be containing Ness' arch-nemesis Porky Minch, an evil child serving the Subspace Army as a major member, operating his trademark spider mech. Lucas and Ness team up to defeat Porky in an extended battle.

Lucas and Ness are then attacked by Wario, who fires his Dark Cannon at Ness repeatedly. After several misses, Wario aims his weapon at Lucas, and Ness sacrifices himself to save Lucas with a shove. As Wario lets out his evil laughter over his new trophy, a frightened Lucas runs away. Shortly afterward, Lucas runs into the more confident Pokémon Trainer, who is in the area seeking out more Pokémon to catch and currently owns a Squirtle. The two boys travel together from that point forward.

Elsewhere in the World of Trophies, in the middle of a vast, desert-like battlefield, swordsman prince Marth is standing on his fortress as he observes some R.O.B.s detonating a Subspace Bomb far out in the field. Marth races to investigate and find out how to stop whatever devastating plot's going on, but his fortress is besieged by the Subspace Army, forcing him to fight his way through repeated swarms of enemies until he gets to the grounds outside of the fortress. When he reaches the zone of the detonated Subspace Bomb, Meta Knight flies in and attacks Marth for some reason or other, and the two duel briefly, but soon they find they are surrounded by Subspace minions. The swordsmen quickly see that they aren't enemies with each other, and team up to battle the wave of Subspace Army grunts. After the battle, the two catch sight of the Ancient Minister carrying yet another Subspace Bomb, and they desperately try to catch up to him but fail. Out of nowhere, a third fellow swordsman named Ike appears where they are and attacks with his Aether sword technique, severing the unset bomb from under the Minister and sending the Minister whirling off into the sky. Ike joins the other two to form a swordsman trio that proceeds to pursue the Ancient Minister and attempt to stop him again.

By this point, King Dedede has learned that Bowser and Wario have joined the Subspace Army and are turning fighters into a collection of trophies. With his Dedede Brooch gambit in mind, he decides to start his own trophy collection. On a remote road, he and his Waddle Dee underlings find, subdue, and trophy-ize a lone Smasher, Mario's lankier and more timid brother Luigi. Right as Dedede does this, he sees Wario passing by on his Cargo with the trophies of Ness and Peach/Zelda in tow, and figures this is a perfect opportunity to collect more trophies for himself. Dedede places the Luigi trophy alone on the road to lure Wario, and when Wario tries to collect this apparent freebie he is ambushed and swarmed by Waddle Dees while Dedede takes away the Luigi trophy and steals Wario's Cargo and drives away with it. Now Dedede has added Wario's previous trophy acquisitions of Ness and Peach/Zelda to his trophy collection, and Wario, of course, is greatly annoyed.

Chapter Four
In a thick forest in the southwest region of the World of Trophies, young elven warrior Link, a close acquaintance to Zelda in the same way as Mario and Peach are associated, comes across the podium in which his trademark weapon, the Master Sword, is set into, and draws out and holds his sword once again. Shortly after, Link watches the Halberd pass over his airspace and deposit Subspace Army forces into his area. A sleeping denizen of the forest, the dinosaur Smasher Yoshi, wakes up to see this as well, and he and Link very quickly decide to team up to try to pursue the apparently threatening commodity that is the Halberd, fighting Subspace Army goons along the way.

On the Isle of Ancients, a young woman named Samus Aran, an athletic and capable Smasher even in just her Zero Suit, has infiltrated the floating island and is now sneaking her way into the research facility areas, battling and defeating R.O.B. minions along the way. She soon comes upon a room where a captive electric Pokémon named Pikachu is trapped in a generator, with its electric qualities being cruelly siphoned to power the area's machines and technology. Samus breaks the sapping device with her Plasma Whip to save Pikachu, which sets off an alarm and causes many R.O.B. minions to enter the room and attack. Zero Suit Samus and Pikachu team up and battle their way through the facility, and soon find a control room where Samus determines the location of what she has been apparently seeking out in the facility: Her personal Power Suit.

Kirby and Zelda/Peach have traveled to the shore of another lake following their hands-on experience with the Halberd back in Skyworld. Kirby sees King Dedede (these two are rivals as well) go by in the Cargo, and he chases after it, leaving Zelda/Peach behind. Right after this happens, Zelda/Peach is rendered a trophy by a surprise attack from Bowser and his Dark Cannon. The Shadow Bug clone of Bowser that has accompanied Bowser comes up to the trophy and swarms over it, then forms itself into a Shadow Bug clone of the princess while Bowser retreats with the original trophy in tow. By that point, Link/Mario and Yoshi/Pit have arrived at this lake and are running through the area in their continued pursuit of the Halberd. The clone of Zelda/Peach tries to shoot Link/Mario and Yoshi/Pit with a Dark Cannon, but the weapon is destroyed when Pit/Link, who has also arrived at the lake shore with Mario/Yoshi, slices it in half with his weapon. The Zelda/Peach clone then faces Mario/Yoshi and Pit/Link and is defeated.

Link/Mario stops running to look up and see Mario/Link and Pit/Yoshi standing by the trophy of the fake clone of Zelda/Peach, which disintegrates. To Link/Mario's eyes this appears as though his lover has been destroyed by the other two Smashers, so in a rage Link/Mario launches an attack against Mario/Link, and their respective companions join the 2-on-2 fray. In spite of their noble vengeance, however, Link/Mario and Yoshi/Pit are eventually defeated by Mario/Link and Pit/Yoshi and turned into trophies. At that moment, King Dedede returns driving his Cargo (Mario/Link briefly glimpses the trophy of his own lover, Peach/Zelda, as part of the Cargo's cargo) to grab the trophies of Link/Mario and Yoshi/Pit with the mechanical arm of his Cargo. But Kirby appears from the back of the vehicle and cuts the arm in half to free the two trophies and immediately proceeds to revive them, to Dedede's shock and annoyance. The revived Link/Pit immediately returns thanks by shooting his bow-and-arrow at Dedede's Cargo in an attempt to slow it down, and the two pairs of Smashers appear to immediately forgive each other and join forces to form a five-man band (including Kirby) as they charge after Dedede's Cargo with the intent to save the other three trophies in Dedede's possession. But even though they run as fast as they can to try to catch King Dedede, and run all the way into and through a cave complex in pursuit, the five heroes eventually glimpse Dedede's castle far in the distance, with the Halberd appearing to approach it. To reach the castle, they must go through a second cave complex.

In a control room somewhere, Ganondorf, who knows that Dedede and several Smasher trophies are in the castle below the Halberd's position, transmits the castle's coordinates to Bowser, and orders Bowser and his troops to track down Dedede.

Chapter Five
At a remote mountain near the ruined zoo, Lucas and the Pokémon Trainer see a dragon-like Pokémon named Charizard fly into a cave, and Lucas tags along as Pokémon Trainer follows Charizard down a path into an extensive series of ruins both underground and above ground. The two journey through the ruins and across an active lava pit until they confront Wario by the entrance to another underground ruin's cave's entrance. Seeing Wario and remembering Ness, Lucas grows bolder and joins the Pokémon Trainer's Squirtle to fight Wario and defeat him, which turns him into a trophy. Lucas is uplifted after having passed this test to overcome his own timidity, but he suddenly remembers Ness, and Lucas is distraught to see that the trophy of Ness that Wario originally took is nowhere in sight. Pokémon Trainer cheers him up by suggesting that Ness might be in the next set of cave ruins

In his personal castle, King Dedede decorates his three trophies - Peach/Zelda, Ness, and Luigi - with his Dedede Brooches. He realizes he only has enough Brooches for the three trophies, and though dejected by the thought of having to take off the one he intended for himself to put it on the princess' trophy, he does so, intending to make another Brooch for himself later. However, at that moment Bowser and his troops crash into the castle and attack King Dedede, knocking him unconscious into trophy form and trashing his lair. Bowser then sees the trophy of Peach/Zelda - the other princess he has been wanting to capture since his capture of Zelda/Peach earlier - and grabs it and runs away from the castle, unaware of the other trophies of Luigi and Ness he's leaving behind buried under the rubble.

By this point in time, Mario, Link, Pit, Yoshi and Kirby have cleared the cave complexes leading to the castle, and when Mario sees his personal nemesis Bowser he attempts to punch him; Bowser forces Mario to miss by holding up Peach/Zelda's trophy as a shield. Pit fires an arrow that Bowser barely dodges, but which causes the Dedede Brooch to come off of Peach/Zelda's trophy. Bowser then gets in his Koopa Clown Car and heads back to the Halberd above with the Princess' trophy in tow, to the inner frustration of Mario and his group. Kirby in the meantime investigates the dropped Dedede Brooch, and his instinct for gluttony prompts him to inhale the Brooch and keep it within himself for the time being. While all this is happening, the Ancient Minister and his R.O.B. minions deploy and set a Subspace Bomb outside of Dedede's castle, and as Ganondorf watches on the display screen in his control chamber, the detonation engulfs the castle (and the trophies of Dedede, Luigi, and Ness inside it). Ganondorf then receives new orders from Master Hand on his display screen.

Back at the underground ruins which Lucas and the Pokémon Trainer continue to explore in search of their respective goals (Lucas searches for Ness' trophy while Pokémon Trainer seeks wild Pokémon to battle and capture), fighting off the Subspace Army all throughout their trek, Pokémon Trainer encounters and captures two Pokémon to add to his collection: The plant-lizard Ivysaur and the fire-breathing dragon Charizard which they saw earlier. The two boys eventually make it into a great underground hall, which for all intents and purposes is a dead-end for them.

Back at the desert-like area, Marth, Ike, and Meta Knight see a colossal, mechanical agent of the Subspace army named Galleom patrolling the desert, and they decide to pursue it through the desert until they engage it and defeat it in battle. Though Galleom proves to be a fiercely powerful opponent, the swordsmen do defeat it, but the still-operational beast leaps down a nearby cliff face into the front of the cave ruins. The ground below Galleom collapses under its weight because there is a huge empty hall right below its position, so it falls down into the ground to end up at the bottom of the giant hall... right where Pokémon Trainer and Lucas happen to be located. Galleom immediately attacks the boys in its second battle in a row, but they defeat the robot like the swordsmen did before. Thoroughly weakened, Galleom sets a Subspace Bomb with a 15-second countdown timer hidden within its head as an emergency feature, and grabs the boys and flies upwards out of the hall, out of the ground and into the sky, intending to take them all out with a sacrificial Subspace detonation. The Pokémon Trainer has fainted, much to Lucas' despair, but Lucas, now gaining his courage, uses his own PK Thunder attack to blow apart Galleom's arm and sever themselves from the robot's body. They both enter free fall to what seems like certain doom, until Meta Knight - who had been watching events unfold from nearby with the other two swordsmen - flies and catches them both at the last second. Behind them, Galleom's Subspace Bomb detonates at around the mountain, sucking up the Wario trophy that was left behind at the mountain's cave entrance into Subspace. Lucas and the Pokémon Trainer happily share a handshake while accompanied by the three swordsmen.

Chapter Six
The Ancient Minister, witnessing the detonation of Galleom's Subspace Bomb from a different region of the same desert, continues to exhibit an increasing sorrow over the sacrifices of his R.O.B. brethren that occur whenever they set and detonate such a bomb themselves. He now has another Subspace Bomb in tow, which he is to deploy elsewhere in the desert. Mario's five-man group reappears to confront and chase the Minister, and the Minister continues to elude their best attempts to stop his operation, firing shots at the heroes all the while. R.O.B. minions successfully set-up and activate the Subspace Bomb's inevitable countdown timer, which cannot be stopped however hard the Smashers try, and as the detonation ensues, one R.O.B. unit waves "good-bye" at the Minister, who looks depressed to say the least. Mario's group just barely manages to escape the huge Subspace explosion.

Fox and Diddy Kong have been traveling east through the jungle and swamp since their last encounter with Bowser, which had ended by jumping off a cliff, and they have been continuing to battle Subspace Army goons and Bowser's troops. As they eventually leave the jungle, Diddy is suddenly shot by a Dark Cannon blast, shot by Bowser making yet again another reappearance, and a swarm of Shadow Bugs under Bowser's command crawls over Diddy's trophy, then form a Shadow Bug clone of Diddy. Fox appears to be out-manned and about to be turned into a trophy himself when his wingmate, fellow pilot Falco Lombardi, flies in in his own Arwing and jumps out to save the day. He kicks the Dark Cannon out of Bowser's hands and destroys it with his two blasters. A seething Bowser hops in his Koopa Clown Car and must flee, but the clone of Diddy then absorbs many more Shadow Bugs to grow to twice its size. Fox quickly revives the original Diddy, and the three team up and battle and destroy the evil clone together.

After the battle, Falco is about to head off on his own when he is stopped by Diddy, who tries to enlist Falco's help in searching for Donkey Kong, and Diddy soon has to resort to literally dragging Falco behind him by his collar. Falco, Fox and Diddy then travel together and battle their way through a swamp as they face more troops and Subspace minions. At a river ending in a cliffside waterfall, they eventually see a flying transport with DK's trophy on it fly off towards the Isle of Ancients in the sky in the distance. Falco calls for support in the form of the Great Fox, Fox and Falco’s co-owned command vessel, so that the three Smashers can fly in the direction of the transport.

Samus and Pikachu continue their exploration through the Isle of Ancient’s research facility in search of Samus's Power Suit, encountering and battling their way through more R.O.B. units and Subspace Army grunts. Upon finally reaching the room with the suit, the pair are confronted by two Shadow Bug clones of the Suit, which they soon dispatch. Soon, Power Suit Samus is back in action, and together she and Pikachu continue their run through the base in search of whoever is leading the R.O.B. units so that they can shut down the base. When they reach a particular dead-end, however, Samus is assaulted by her arch-nemesis, the dragon-like Ridley and major Subspace Army member, who keeps up a thorough, brutal onslaught upon Samus until Pikachu saves her by attacking Ridley with its Thunder attack. While Samus is fazed from the experience, she and Pikachu team up to successfully defeat Ridley. The two victorious Smashers proceed to exit out of a secret door into the exterior portion of the Isle of Ancients, whereupon they see some R.O.B. units carrying Subspace Bombs out of another part of the base that appears to be a factory for Subspace Bombs. Samus and Pikachu decide to reenter the base through that opening with sabotage likely in mind.

On another exterior portion of the Isle, outside a set of ancient ruins, a little astronaut named Captain Olimar is engaged in commanding his plantlike minions, the Pikmin, to attack an oversized R.O.B. unit. All of a sudden, an extremely fast racing machine piloted by spandex-clad bounty hunter Captain Falcon zooms into view, and Captain Falcon leaps out and destroys the R.O.B. with a decisive Falcon Punch… But as he lands, he accidentally wipes out most of the remaining Pikmin. That mishap aside, the two captains decide to team up and fight their way through that area of the Isle, and they make it to the isle’s edge. There, they watch as the transport carrying Donkey Kong's trophy approaches the island, and Falco's Arwing flies in, which drops Diddy onto it, who in turn blasts the Subspace grunts occupying the transport and revives Donkey Kong. Captain Falcon decides to act as a Good Samaritan by jumping down onto the transport with Olimar in tow and introducing themselves to the apes, and when more waves of the Subspace Army attack, the four of them battle the forces off together. The transport then autopilots itself into the interior of the Isle, giving the two captains and the two apes the perfect opportunity to sneak in and strike at the core of the menace from within...

Chapter Seven
Back in the desert, Meta Knight sees the Halberd engaging in a battle with the Great Fox near a mountain. Leaving Marth, Ike, Lucas, and the Pokémon Trainer behind on the ground, he takes off after the warship and charges his way up the mountain. Along the way he passes by a pair of mountain-climbing parka-clad children named the Ice Climbers currently hiking up the mountain, and they take Meta Knight’s course as a challenge, so they try to get up to the top of the mountain before him. Meta Knight and the Ice Climbers eventually make it to the glacial peak after having to fight through more of the Subspace Army together.

At the peak of the glacial mountain, Meta Knight encounters a meditating, mystic Pokémon named Lucario, who challenges Meta Knight to a duel. Meta Knight/Lucario wins the battle, and he revives Lucario/Meta Knight from his trophy-state afterward, with the two combatants shaking hands in respect. Just then, the Halberd, which has won its battle with the Great Fox and has it tied underneath itself, rams the Great Fox into the mountain, causing the Ice Climbers to fall off to the bottom, but Meta Knight and Lucario manage to jump onto the ship and enter its interior. The Ice Climbers in the meantime meet up with Marth, Ike, Lucas, and the Pokémon Trainer at the bottom of a mountain canyon, and are subjected to another wave of Subspace Army soldiers, but luckily Mario's five-man group arrives and jumps down to help out the other group in combating the Subspace Army. After a long fight, the two teams are victorious.

Inside the Halberd, out of a cardboard box disguise emerges a special forces agent codenamed Solid Snake, who had infiltrated the Halberd much earlier in the story for the likely reason that he is trying to combat the menace of the Subspace Army in their own battleship in his own way. As the heavily damaged Great Fox is seen flying away from the Halberd, Snake continues to sneak through the battleship, but quickly hides himself in his box when he hears Meta Knight and Lucario approaching his position. As the other two Smashers pass by, Lucario’s attunement to Aura allows him to sense Snake in the box, and Lucario blows Snake’s cover by lifting up the box. With another wave of Subspace Army units on the way to attack them, though, Snake joins Meta Knight and Lucario in combating their way through the battleship. The three make their way into a room that has Zelda and Peach's captive trophies in cages; almost immediately, Shadow Bugs swarm over the Trophies and create Shadow Bug clones of them both to fight. After the clones are defeated, the princesses are freed and revived, and Snake tells them to stay put in the room while he and the other two keep looking around.

After Snake, Meta Knight, and Lucario leave, Zelda transforms into her alternate guise Shiek and she and Peach make a battle-filled journey of their own on the exterior of the Halberd in spite of Snake's order, eventually making it to the front deck of the Halberd. At the same time they arrive at that area, Fox, now piloting another Arwing, engages the Halberd again, and destroys one of the battleship’s turrets, but the explosion occurs dangerously close to Peach’s current position. Sheik, thinking Fox was shooting at Peach, teleports onto Fox's Arwing and punches straight through the canopy, and hurls Fox out of the Arwing onto the front deck. The two are about to engage in a violent fight when they are stopped by Peach, who offers each of them a cup of tea. Fox is stunned, but realizes that Sheik and Peach aren't his enemies.

In the meantime, Snake, Meta Knight, and Lucario have made it to the Halberd’s main control room, where they discover several copies of what appears to be Mr. Game & Watches infesting the place. They send the clones flying through the windows of the control room onto the main deck where Fox and the princesses are, and the clones melt into Shadow Bugs, which merge into a gigantic, immensely powerful mechanical monster named Duon. As Meta Knight stays behind to regain control of his ship, Snake and Lucario jump out to join Peach, Sheik, and Fox, and Falco jumps out of his Arwing to join the fight as well. The six heroes engage in an intense fight with the monster and eventually defeat it, and the monster melts and leaves behind the intact trophy of Mr. Game & Watch. Peach revives Mr. Game & Watch, and after scolding him for the trouble he caused, she lets him join their group. Now, the Halberd has been retaken.

Chapter Eight
Back at the Isle of Ancients, Samus and Pikachu’s infiltration of the Subspace Bomb Factory plays out at the same time as Donkey Kong, Diddy Kong, Captain Falcon, and Captain Olimar’s own infiltration of the Isle’s same factory complex. Thus, the two groups of Smashers cross paths with each other, in the final room of the Isle of Ancients… and are all faced with none other than the Ancient Minister, the full remnants of the R.O.B. Squad, and hundreds of Subspace Bombs. The Ancient Minister hangs his head as if he is sad, though, and appears entirely unwilling to perform any more detonations, but then a holo-projection of Ganondorf appears and gives the R.O.B. Squad the command to set every bomb in the facility simultaneously. The Minister defiantly stands in the way of his brethren to stop them, but Ganondorf manually controls the enslaved R.O.B.s and have them attack their former "master", setting his cloak aflame. Then as the R.O.B.s set each bomb, the other Smashers desperately try to stop them and their bombs, but to no avail. As Ganondorf's projected image disappears, he summons hordes of Subspace minions to distract the heroes.

The burning Ancient Minister chooses now to shed off the flaming cloak and reveal his true appearance and identity to the Smashers as the Master Robot of the R.O.B.s and a Smasher himself, and officially joins forces with the other Smashers in battling the Subspace minions. After the battling, though, it is all too clear that the detonation of the Subspace Bombs are inevitable. Captain Falcon remotely calls his personal flying ship, the Falcon Flyer, to arrive in the Isle of Ancients so that everyone may escape from the island in time. After R.O.B. and his brethren bid a final, melancholy farewell to each other, everyone piles into the ship and flies off towards the isle's exit at full-speed. However, Ridley reappears, now having been reconstructed as a cybernetic version of himself named Meta Ridley, and pursues the Falcon Flyer as it tries to make its escape. The Smashers must set the Flyer's autopilot on, then climb onto its roof to engage Meta Ridley in a high-velocity mid-air clash. They soon manage to defeat Meta Ridley in time to pilot the Falcon Flyer out of the Isle of Ancients, as the floating island is completely engulfed in a titanic Subspace explosion generated by many Subspace bombs set off simultaneously in close proximity.

In the desert, Mario, Link, Pit, Yoshi, Kirby, Marth, Ike, Lucas, Pokémon Trainer, and the Ice Climbers witness the Subspace explosion as it occurs far off-shore. The Falcon Flyer containing R.O.B., Donkey Kong, Diddy Kong, Samus, Pikachu, Captain Falcon, and Captain Olimar flies in and lands near the other group of Smashers, and at the same time the Halberd, containing Meta Knight, Peach, Zelda, Fox, Falco, Lucario, and Snake, arrives and lands near the others. The two-dozen-plus Smashers fully acquaint themselves with each other and presumably discuss matters at hand.

Chapter Nine
Out of the huge rift between realms left behind by the detonation of the Subspace Bombs at the former location of the Isle of Ancients, the completed Subspace Gunship halfways emerges out of Subspace into the World of Trophies; indeed, the purpose of the original detonation of so many Subspace Bombs was to open a rift between realms physically large enough to allow the Subspace Gunship through. (It was also because there would be no need for the Subspace Bomb Factory at the Isle of Ancients anymore once the Gunship enters the world.) The incredibly large main cannon, as operated by Ganondorf and Bowser visible on the vessel's top canopy, produces a test-shot at an off-to-the-side area of the ocean that generates a huge Subspace explosion.

Then, Ganondorf and Bowser see the Halberd charging forward towards their position at full throttle. At Ganondorf's order, the hundreds of turrets lining the Gunship begin firing their lasers all at once; the Halberd, though able to dodge several shots, is completely destroyed in an explosion from the onslaught. Immediately, however, the lesser aircraft containing all the Smashers - the Falcon Flyer, Samus' personal gunship, Fox and Falco's Arwing, and Captain Olimar's personal Hocotate rocket - emerge from the dust cloud, zooming towards the portal to Subspace connected to the Subspace Gunship and skillfully dodging every round of turret fire. Then Kirby, individually piloting his personal "ultimate" ship the Dragoon, flies straight into the Gunship and pierces it cleanly, causing the Gunship to begin exploding and disintegrating from the inside. Ganondorf and Bowser must return to Subspace, while the other five ships manage to enter Subspace. Now inside the realm of Subspace, the combined force of Smashers - Mario, Peach, Donkey Kong, Diddy Kong, Yoshi, Link, Zelda, Samus, Pit, Ice Climbers, R.O.B., Kirby, Meta Knight, Captain Olimar, Fox, Falco, Captain Falcon, Pikachu, Pokémon Trainer, Lucario, Marth, Ike, Lucas, Mr. Game & Watch, and Snake - begin their exploration of the Subspace realm in search of whatever is responsible for the Subspace invasion and to put a stop to it.

Ganondorf and Bowser are on their way to report to Master Hand, but Ganondorf decides now is the time to go through with his intended plan to usurp the power of the Master Hand, so he turns his Dark Cannon on Bowser and renders Bowser a trophy without Bowser ever knowing. Then he meets Master Hand in person... but immediately sees the chains of light binding Master Hand, and looks upon the puppetmaster Tabuu for the first time - the true orchestrator of the plot to send the World of Trophies into Subspace. Shocked and angered that he has been used by Tabuu the whole time, Ganondorf leaps forward to attack Tabuu, but the incredibly powerful entity attacks Ganondorf and turns him into trophy form without much exertion. The force of the impact of Ganondorf's trophy against Master Hand physically snaps the chains of light from Master Hand, who falls to the ground free from Tabuu's mind-control. Master Hand regains his composure and immediately and angrily tries to attack Tabuu with all he's got, but he too is defeated very easily. The force of Smashers arrive in time to witness the fallen Master Hand and look upon the master of Subspace, but before they have an opportunity to do anything, Tabuu seizes this incredibly convenient opportunity, stretches his wings, and releases his full-powered Off Waves. Every single Smasher is instantly trophy-ized without further incident.

As the Smasher trophies are scattered and lost within the Subspace realm, Tabuu takes the portions of the World of Trophies that prior Subspace Bomb detonations had sent to his realm, and rearranges them to construct a nightmarish, extensive maze, filled with shadowy versions of fighters and reincarnations of major Subspace Army members and other monsters (including Ridley, Duon, and even Rayquaza), all of which were created based on detailed analysis carried out by the Subspace Army. The creation and future expansion of this twisted project was apparently Tabuu's desire all along in wanting to assimilate the world of Trophies into Subspace, and now with quite literally every Smasher in the World of Trophies turned into a trophy and removed as a threat to his operation, there appears to be nothing else that could possibly stop Tabuu from taking the rest of the World of Trophies for himself.

Chapter Ten
In the portion of the Subspace Realm currently containing the World of Trophies area containing Dedede's castle, and thus the inanimate trophies of King Dedede, Luigi, and Ness within, the timers within the Dedede Brooches attached to Luigi and Ness reach zero, and suddenly revive the two Smashers. After a moment of gathering the current circumstances, they make the connection that it was King Dedede who caused them to revive, so they revive King Dedede from trophy-form in return. Dedede is ecstatic that his gambit has paid off and is deeply thankful to Ness and Luigi for reviving him, so now they agree to team up, search the rest of Subspace, and collect and revive the trophies of all the other Smashers. When they reach the area where Master Hand lies motionless and Tabuu's Great Maze is located nearby, King Dedede sees the trophy of Bowser, and revives him. Bowser immediately roars and engages Dedede in battle, who defeats Bowser and turns him back into a trophy. Dedede revives Bowser again, and when the ever-so-pompous Bowser roars and tries to confront Dedede again, Dedede casually smacks Bowser in the face upside, and points him to the rest of the scene. Bowser absorbs the current state of affairs and begrudgingly allows himself to join Dedede's group in combating Tabuu.

Elsewhere in Subspace, Kirby is suddenly and spontaneously revived out of trophy state. He spits out the Dedede Badge he had inhaled a long while back - this is what caused him to revive. Kirby thus sets out on his own exploration of Subspace, battling Subspace Army minions and finding and restoring Smasher Trophies along the way. By the time he makes it to the same area that Dedede is in, Dedede and Kirby have had the potential to collect and restore every Smasher trophy independently. When they first see each other, Dedede gives Kirby the famous "Dedede glomp", and enthusiastically drags Kirby along for the final confrontation in Tabuu's Great Maze. At the same time, Bowser physically vents out his anger at Ganondorf's trophy in response to Ganondorf blasting him with a Dark Cannon earlier, before heading off to join everyone else in the Great Maze.

If Wario's trophy, which had been sucked into subspace after his last encounter with Lucas at the ruins in the World of Trophies, became one of the trophies that Kirby revived during his run, Wario will briefly confront Dedede over what Dedede had done to him long ago (when Dedede stole Wario's Cargo and trophy collection), but is taken aback to see that Ness and Luigi - two of the trophies he would have had in his possession had Dedede not stolen them - are in support of Dedede. All three of them point Wario to Tabuu's Great Maze nearby to tell him that they are about to engage Tabuu in a battle to the end to save the World of Trophies; Wario, after a moment of self-reflection, hops on his motorbike and rides straight into the maze to assist all the other Smashers. In a similar situation, if Link and Zelda's trophies had been revived earlier during Dedede and Kirby's runs, they then come over to Ganondorf's trophy, and agree to revive him; in the past, prior to the Subspace invasion, Link and Zelda together have had personal conflicts with Ganondorf of their own, but they propose to the newly revived Ganondorf to work with everyone else in the upcoming battle against Tabuu. As the two leave, Ganondorf considers the opportunity to settle the score with his two rivals with an attack from behind and begins charging up dark energy, but soon reluctantly makes the decision to accompany them for the sake of dealing with the larger picture. Thus, the formerly villainous Smashers Bowser, Ganondorf, and Wario, and the other Smashers King Dedede, Luigi, and Ness join the other two-dozen-plus Smashers in their greatest challenge.

The Smashers enter and explore Tabuu's Great Maze, reliving the many challenges they faced throughout the Subspace invasion of the World of Trophies, while battling the dark versions of the Smashers and the reincarnated major members of the Subspace Army that were all set up to guard the labyrinth. Through an epic, lengthy, and combat-filled exploration all across the Great Maze, the thirty-plus heroes finally reach Tabuu. Tabuu immediately spreads his wings and readies a second helping of his Off Waves assault, but all of a sudden, out of nowhere a new hero arrives: An extremely speedy hedgehog named Sonic the Hedgehog flies straight through Tabuu's wings and shatters them, crippling his trophification ability. The weakened Tabuu, having been caught off guard by this attack, proceeds to engage in combat against the Smashers outright, and Sonic joins the other heroes in facing Tabuu down in the final struggle. Tabuu is the most powerful opponent they have faced, but in the end Tabuu is finally defeated. Tabuu explodes, which sends all of the segments of his Great Maze back to their former locations in the World of Trophies, restoring them all to normal, and all the Smashers manage to escape the Subspace realm back to their world.

The World of Trophies has been saved, and the thirty-plus heroic Smashers stand triumphant on a cliff face and share a brilliant sunset. This victory has not been without a heavy price, though: the sheer number of Subspace Bombs involved in the explosion that consumed the Isle of Ancients has prevented that area of space from ever being able to return to normal in spite of the complete removal of Subspace, so the Isle is permanently gone, with an X-shaped mark of light remaining in its place. As such, R.O.B. remains the last of his kind.

Dialogue
The vast majority of character interaction in the Subspace Emissary takes place through gestures and expressions, augmented by short grunts or exclamations. The only spoken words besides a quick "Hey!" or "Yeah!" are those that are a distinctive part of a character's attacks, like PK Thunder or Falcon Punch, or taunt-like sounds that have been put in key places. However, in the cutscene preceding the stage 'Battleship Halberd Interior', Solid Snake, after revealing himself, says to the camera "Kept you waiting, huh?".

Similarities to Kirby Super Star
Because both games were developed by Masahiro Sakurai, The Subspace Emissary contains gameplay elements similar to the sub-games of Kirby Super Star. One should keep in mind that the Kirby series and Smash Bros. franchise are two different things.


 * The Halberd plays a very strong role in both games.
 * Being chased down by the Pig King Statue is similar to being chased down by the Heavy Lobster (including the enemy activating switches and destroying anything in its path).
 * Both feature cart rides and special devices that propel characters forwards.
 * The Space Jump is just like how P2 from Super Star comes back to P1. Also works in Co-op.
 * The final boss (Tabuu) teleports around the stage repeatedly (a common feature in most Kirby games).

Trivia

 * In the Subspace Emissary, you cannot get Star K.O.ed - you crash into the top of the screen; this does not apply when you're fighting a Subspace Clone in the Great Maze or a boss.
 * Luigi cannot rise in the air above a pathetic bare minimum using his Luigi Cyclone, as opposed to the attack's large recovery when Brawling. It is believed this is because the gravity of the Adventure mode is slighty higher than that of normal matches.
 * The Pokemon Trainer's Pokemon will not tire in Adventure Mode. So one can apply stickers to his or her favorite Pokemon out of three with no problem.
 * The running speed of some characters has also been decreased, however, any character that Player Two controls will have an increased dash speed if Player one is somewhat ahead.
 * However, everyone can swim a little longer in any of the bodies of water you can find.
 * The Ruined Zoo is a location from the first Mother game, though it is commonly believed that the Halberd is the only location from a past game.
 * The Subspace Research Facility looks suspiciously like Angel Island from the "Sonic the Hedgehog" Series
 * If you pick Kirby to beat Mario, look closely to the trophy of Mario hit the ground. His right eye isn't there.
 * In the mode's cutscenes, whenever a character is introduced with their name appearing on-screen, the accompanying sound is lower for villainous characters than for heroic characters.
 * For whatever reason, Mr. Game & Watch is never formally introduced.
 * Mario and Kirby fighting might to be a reference to the Super Smash Bros. Melee intro, which Mario and Kirby are seen fighting in an stadium. Another similarity is the Mario trophy "coming to life" as it lands in the stadium.
