The shot opens on the giant battlefield saw in the More Fighters trailer.
Mario and the rest of the Smash cast are caught in an epic battle with sides split evenly down the side. Mario against Link, Pikachu against Kirby, Sonic vs Banjo, and so on. Suddenly, as they are about to head off in a titanic clash, the ground begins to shake violently and someone in the distance catches their attention.
Kirby, seemingly the bravest in this moment, steps forward. He sees a crack in the ground beneath his feet. He looks forward, and the camera moves forward in the same direction. We see the crack grow larger as we move forward-then, the camera moves forward even faster, until it suddenly stops on a black shadow.
Then, the character shows himself-it's Issac! His series theme starts to play, and a ray of sunshine shines down on him from above. He used his powers to create the earthquake. He waves at the competition with a friendly smile.
Suddenly, two figures teleport behind him-it's Eleven (DQ) and Mewtwo! The two of them give a determined look, indicating they're looking to start Issac's first official battle in Smash. Issac nods and brandishes his sword, as does Eleven. Mewtwo starts to charge a Shadow Ball.
Then, Eleven runs forward and swings. Issac blocks with his own sword, then while holding Eleven there, uses Quake to send him flying. Issac then grabs Mewtwo with Catch and throws him in the same direction as Eleven was flung. Then, a bunch of fighters-including Cloud, Bowser, Ridley, Little Mac, and more-dive in on Issac all at once, like American Football players diving for a ball. They form a sort of huddle of bodies around Issac, trying to take him down. Then, the huddle starts to glow from the inside, a bright, yellow light. An explosion is heard, and everyone in the huddle flies away in pain-except Issac, who floats there before dropping down. He looks quite tired from his Gaia attack. But he isn't resting for long, as another earthquake is felt beneath his feet. He and the rest of the Smashers look to see who or what caused it. The camera follows a large crack in the ground, one that gets smaller as we go up. Then, the camera goes faster, and stops at the source of the crack. There's a small, almost circular figure, who stands at the base.
Then, we see who it is-it's Bandana Dee, with his fist in the ground! He does a classic Kirby pose with his spear in the air, looking very happy to be here.
We see Kirby and King Dedede. Kirby is waving and smiling, and Dedede is jumping up and down in excitement. The other Smashers seem pretty happy too. But Meta Knight isn't having any of it-he flies forward at tremendous speeds, knocking over those two onto the floor with their feet hanging comically in the air.
Bandana Dee looks surprised, then readies his spear with a determined look. In no time flat, Meta Knight is there, and he swings his sword just as fast as Bandee blocks. Time slows as the sword and spear crash together. We get a zoom-in on Bandana Dee's face, who seems to smirk knowingly. Meta Knight is not amused. They trade some more blows, time slowing down at some of the strikes before immediately picking back up again. Then, when Bandana Dee blocks yet another attack with the middle of his spear, he kicks Meta Knight with a ton of force, catching the mysterious swordsman off guard. Bandana Dee breathes a sigh of relief.
Then, he sees another fighter running straight at him-it's Byleth! He charges a move that is uncannily similar to his forward smash. He unleashes it, upwards slightly-but Bandana Dee is ready, and he thrusts his spear as well-leading to a beautiful, balanced shot where the two spears collide, both facing the sky.
The two of them continue fighting, but the camera moves from them-instead focusing on another battle, this one between veterans. It's a boy and girl Inkling vs Snake and Banjo. The four make heavy use of their respective projectiles. Then, the Inklings use some Splat Curlers to make a hasty retreat in order to get more ink, swimming off in the direction opposite of their opponents. Snake looks impatient, and Banjo throws a blue egg up and catches it, and throws it up again, sharing Snake's frustration.
We see the Inklings pop back up, behind a rock that lets them hide from Snake and Banjo. They pull several weapons out of their pockets, throwing them on the ground, trying to figure out which one would be the best to use. Then, they look down and see the blue and orange ink isn't there anymore-but what is, is a new color of ink, one they haven't seen before. Behind them, a figure with the outline of an Inkling rises up from the ink behind them. This figure splats both of them instantly with a Dynamo Roller, rendering them Squid Ghosts. We then see the figure-it's a female Octoling! She swims through her ink, then appears at the same place where Orange and Blue Inklings stood, fighting Snake and Banjo. The two seem surprised at this new ink-splashing opponent, but are excited to have another challenge. Then, a boy Octoling appears next to her, rising from the same ink. Then, the four enter a projectile barrage, which is used to show off the new weapons that the Octolings would bring with them to Smash.
Suddenly, Snake throws a smoke grenade forward, and the Octolings lose their vision and start coughing. Then, when the smoke clears up, they don't see anyone-only an inconspicuous box. They run off in search of another fight. Then, when they are out of earshot, Snake lifts up the box, revealing him and Banjo and Kazooie hiding under. Banjo is doubled over in fear, but relaxes once the box is lifted. Kazooie wipes the sweat off her forehead.
Then, we see another battle occuring-a three-way fight between Dark Samus, Little Mac, and Isabelle. In the center of the fight is an item everyone has yet to pick up-an Assist Trophy. But this Assist Trophy starts to...move? It's trembling. Then, a crack. Then, multiple cracks. It gets so loud that Isabelle stops fighting and bends down to look at the Assist Trophy. She goes to pick it up, but just as she does…
WAHAHAHAHA!
A tall, purple-clad, and admittedly handsome fellow crashes out of the Assist Trophy-it's Waluigi! He swims through the air, then falls to his feet, holding a tennis racket and a ball, which he spins around on his finger. He then throws it up to serve.
Dark Samus shoots a charge shot at him, but he jumps up high to avoid it. He is now level with the ball in the air, brings his racket high above his head, and brings it down upon the ball, which crashes into Dark Samus, sending her flying. Isabelle pockets the tennis ball so Waluigi cannot use it-but that angers the funny purple man. So he runs over to her and does his multi-kick attack, burying her, and then serves her away with his racket. Little Mac tries to use a dash attack on Waluigi from behind, but he notices this, and moonwalks out of the way, very fashionably. When Mac turns around to try another attack, Waluigi pokes his eyes. Mac yells in pain and falls onto the ground, dazed.
Just then, a giant golden hand punches Waluigi, knocking him back a bit-but he picks himself up. Waluigi looks up to see Issac, ready to pick a fight. Issac reaches out to Waluigi with a vine attack-and Waluigi does the same, with much scarier, less lively vines. They tangle into each other, and so begins the battle of former Assist Trophies.
We see another shot, this time of Mario and Sonic having a battle. Sonic dodges one of Mario's fireballs by jumping-but as it turns out, this is exactly what Mario wanted, and he does a famous FORWARD AERIAL on Sonic, who creates a crater on the ground from his impact.
We can see in the distance, a sort of crack in the air, like an invisible window was just hit. Then, a mysterious portal opens up, which catches the attention of the two Smashers. The two look confused-that is, until they see one of the two figures that come out.
Crash Bandicoot! He jumps out of the portal, but looking around, he seems confused. His sister Coco follows, joining him in looking bewildered. "This isn't the right place-or, time?-I think. We better head back."
Just then, Crash sees Mario and Sonic off in the distance! His tongue drops out of his mouth and he runs toward them, like an old friend.
Sonic cracks his knuckles and smiles, eager to rejuvenate a decades-old battle. Mario seemingly has an idea-he throws Cappy at Sonic, capturing him. Mario/Sonic runs at Crash, and Mario has a hard time controlling his speed. When close enough to Crash, Mario leaves the vessel, leaving Sonic on the ground, dazed and confused.
Mario jumps towards Crash, and Crash does the same. Mario swings out another meteor punch, but Crash dodges it with a double jump, and now above Mario, performs a body slam. Now Mario is the one in an earth-shattering crater.
Sonic is charging up a Spindash, and when he's done, instead of letting it rip, he takes a professional runner's stance as they are about to run a race. "Ready…" he says. Crash looks a bit confused.
"GO!"
Sonic does a Light Speed Attack, hitting Crash multiple times before he can react. Crash regains his footing and does a spin attack, knocking Sonic away.
At the same time, Mario and Sonic both get back up, and start charging at Crash from the left and right. The two punch Crash from either side, but Crash blocks both hits with his arms. He smiles, looks and winks at each one of them in turn, and then spins, knocking them away.
While they continue fighting, we see another three-way fight going on, which the camera focuses on-Ryu, Ken, and Terry. There's Hadoukens, Shoryukens, Power Dunks, Power Waves, it's total chaos. Peach, Zelda, and Daisy watch from the sidelines. Peach claps politely, Daisy jumps up high and raises her fists to cheer them on, and Zelda stays quiet, but smiling.
Terry knocks Ken away with a well-placed Power Geyser. Then, Ryu trys a Focus Attack, but Terry jumps over it, does a down air-like move that knocks Ryu down and in front of Terry, and then Terry rushes towards the still-aerial Ryu, and grabs him by the collar of his gi.
"Are You OK?!"
"...Perhaps…" Ryu says with a smile.
Terry smiles back. "BUSTER WOLF!" Ryu flies off in the distance, far, far away. The spectators cheer for Terry. Peach even blows a kiss to the winner. Terry notices this and blushes, tipping his iconic hat down.
"ACK!" Terry is hit hard from behind. He is launched just as the previous two Shotos were. Peach, Zelda, and Daisy all look surprised, then look even more surprised when they see who knocked him out. We see yet another dark outline. (At this point, fans are wondering "Scorpion? Sub-Zero? Mai? Iori? Chun-Li?")
Then, with a peace sign and a smile, she reveals herself-the Stylist! The princesses give her a polite welcome. She walks up to them and bows in respect, before complimenting their attire.
"But it could use some improvements!"
Time skips, and when Ryu, Ken, and Terry all limp back from being beaten so badly, they see the princesses wearing modern attire like T-shirts and hoodies, with their faces glowing from makeup. (think like the Princess scene from Wreck it Ralph 2). The Shotos look surprised yet impressed. The Stylist walks over to them and offers some of her wares. Within no time at all, Ryu spraying himself with cologne, Ken is trying on a baseball cap (and imitating Terry in a joking way), and Terry is tying his ponytail into a bow (and giving Ken the stink eye). All while this group is enjoying their time together, fighting is going on in the background.
Suddenly, someone starts flying toward Stylist, who is unaware. Sephiroth! He starts to lunge his long, sharp sword towards her-but she dodges, and throws lipstick at him, hitting him square in the head. He turns to her, looking angrier than before-but this is quickly solved when she sprays hairspray into his eyes, causing the god slayer to fall on the floor in pain, covering his eyes and screaming.
After some time, Sephiroth has had his hair braided and is sitting down with is back facing everyone, seemingly in a temper tantrum. Stylist is now fixing up Cloud (making him look like his disguise from FFVII Remake), who is sitting on an iron block that Steve has graciously placed. There is a whole line forming behind Cloud, which includes all of our newcomers-eagerly waiting for their turn. The trailer ends there.
