List of Super Smash Bros. Ultimate trailers

Super Smash Bros. Ultimate trailers have been released to reveal all the newcomers in the game.

Inklings
Titled "Super Smash Bros. is coming to Nintendo Switch!" as it also served as the reveal of the game, the trailer starts out with a white background. Soon, 2 Inklings appear and fight a battle in vain of Splatoon and Splatoon 2. Later on, the white background slowly fades into black, and the music begins echoing and then stops. The camera zooms in on Inkling Girl. A light appears behind her. She looks, and the camera zooms in on her eye. a smudge appears on it and is later revealed to be a fiery Super Smash Bros. logo. The camera zooms out to show it in its entirety, with several figures appearing in the flames. Mario and Link appear with their faces shadowed, along with other fighters around them. Inkling Boy walks slowly towards the flames before stopping. Everything but the Smash Bros. Logo fades. a white background appears and the new text logo of Super Smash Bros. appears on the screen before it disappears and the release date, 2018, appears.

Ridley
Titled "A Piercing Screech", it starts out with a long shot of Mega Man, Mario and Samus treading slowly across a bridge. The camera goes a close shot of them walking and then zooms back out to a bird’s eye view. Mega Man and Mario look around cautiously while Samus looks straight ahead. A sudden flash then takes Mega Man and the screen turns red with a silhouette of him getting impaled in the chest. Mario and Samus continue to walk across the bridge. Then the mysterious creature then takes Mario without his hat and the screen turns red again with a silhouette of Mario being grabbed by the throat. Samus continues treading on without noticing until she realizes that nobody is following her, then taking a deep breath, turns around with her arm cannon pointed. The camera focuses on Samus and then Mario’s cap when a loud clang is heard twice. Ridley then smashes through the bridge catching Samus off-guard. The camera zooms into Samus’s eyes through the visor while a remix of Ridley’s theme starts playing. Ridley then screeches and then spins Mario’s cap on one of his fingers ("Ridley Hits The Big Time!"). The trailer ends off with Ridley hovering in the air with the camera zooming into his face as he sees Samus in her Zero Suit, escape from the wreckage in a high jump and kicks downwards towards Ridley.

Simon Belmont and Richter Belmont
Titled "Vampire Killer", it starts out with a shot of a castle at night during a thunderstorm. It then transitions to a shot of a mysterious hooded figure walking over a puddle of water before stopping in front of the castle doors which have opened. The figure then hears a faint scream from inside the castle, which transitions to the next shot revealing that it was a frightened Luigi fighting off a group of mummies with a flashlight and a plunger mechanism incorporated into his Poltergust, to no effect. The mummies attempt to swipe Luigi who runs away in fear. After stopping to catch his breath, he hears the creaking of a head bust, which causes Luigi to turn and look at the bust, letting out a scream of fright as the eyes glow red in sync with a lightning flash. Scared, Luigi attempts to run away again but almost runs into a candle before running down the corridor as the head bust's hair turns into snakes, revealing that it was Medusa. While running, he trips and falls onto the floor. After getting himself back up, he then sees an ominous figure floating in front of him. Luigi shines his flashlight onto the figure, revealing it to be Death himself. Luigi screams in terror before fainting, leaving him open to a slash from Death’s Scythe, causing his soul to leave his body. Just as Death prepares to harvest Luigi’s soul, a chained spiky ball whip suddenly hits Death right in the jaw, then returning to its wielder, which was the hooded figure from earlier. He then takes his hood off and readies his whip, revealing himself to be Simon Belmont ("Simon Lashes Out!"). He then throws his Cross directly at Death, defeating him and freeing Luigi’s soul. He later encounters Dracula, who he attempts to attack before being knocked back by a fireball. As he crouches, the fireballs float towards Simon, only to be extinguished by his descendant, Richter Belmont, who exclaims "Begone! You don't belong in this world, monster!" ("Richter Crosses Over!"). Simon and Richter then team up to battle Dracula, with Simon using his Cross and Richter using his Uppercut to defeat him. The trailer ends off with Luigi‘s spirit circling his lifeless body. As he tries to get his spirit back in, Carmilla appears in the window, emitting a purple liquid from her left eye (which might be blood), causing Luigi to scream in terror again, and the camera transitioning to an outside view, where it was revealed that they were in Dracula's Castle the entire time.

King K. Rool
Titled "The Rivals", the trailer starts out with illustrations of famous Nintendo heroes battling their famous adversaries, such as Mario battling Bowser who was attempting to kidnap Peach, Link and Zelda battling Ganondorf, Kirby battling Meta Knight, Fox and Falco battling Wolf and Samus battling Ridley (like in "A Piercing Screech") before cutting to black. The next shot then shows Donkey Kong and Diddy Kong napping in their treehouse, with Donkey laying on the floor eating bananas and Diddy resting in his tire swing. The ground suddenly shakes, alarming the Kongs who look outside the window to see what was causing all the shaking. A shadow casts over the window as the Kongs see the silhouette of a familiar foe, who is revealed to be King Dedede in disguise. As both Kongs look on in absolute shock, Dedede then laughs at the outcome of his trickery, unaware that the same silhouette from before comes up from behind and smacks Dedede in the back of the head, causing him to fly offscreen, the silhouette revealed to be none other than King K. Rool himself ("King K. Rool Comes Aboard!"). Donkey Kong and Diddy Kong then scream in terror (with their eyes shooting through the window breaking the glass) as King K. Rool lets out a menacing roar. Then they transition to a shot of King K. Rool and Donkey Kong charging towards each other, before proceeding to jump into the air and collide their fists (Diddy helps out with a kick), the resulting shockwave going across the entire jungle. The trailer ends off with the Kongs having seemingly defeated King K. Rool as they taunt (unaware that K. Rool snuck off-screen) before getting dug into the ground by a larger King K. Rool, who then taunts back.

Isabelle
Titled "All in a Day’s Work", the trailer starts out with Isabelle sorting the mayor’s office and working on her tasks. After performing the tasks, she starts to get tired out but refuses to rest stating that she is almost finished with her work. She then states that she wishes the Mayor (Villager) wasn’t so busy with the campsite (Animal Crossing: Pocket Camp) and the Smash tournaments, later stating that maybe she should be the Mayor instead, but tells herself to stop thinking about it. She then hears the doorbell ring and Pete the mailman comes in with a letter for Isabelle. After Pete leaves, Isabelle starts reading her letter, wondering what it was about. It is then revealed that the letter was an invite to the Smash tournament, with Isabelle caught by surprise ("Isabelle Turns Over A New Leaf!"). The trailer ends off with Isabelle in Onett stating that she hopes she gets cheered on by her peers as she waves.

Ken and Incineroar
Titled "Clash of Flames", the trailer starts out with Little Mac in a boxing match with a silhouetted figure in the Boxing Ring. Just as Little Mac is starting to get the upper hand, the figure punches him right in the cheek, revealing himself to be Ken Masters, who exclaims "Bring it on!" ("Ken Brings The Heat!"). Little Mac attempts to hit him several times, with no success, while Ken unleashes his Hadoken, with Little Mac barely dodging the oncoming attack. As they were battling, a pair of menacing yellow eyes looks on from within the shadows. Just after Ken uses Shippu Jinraikyaku to send Little Mac crashing into the screen, the figure then runs and jumps right into the ring, with Ken jumping out of the way. The figure, engulfed in flames, tears his hat and jacket off, revealing himself to be Incineroar ("Incineroar Enters The Ring!"). After Ken challenges the flaming Pokémon by saying "So, you wanna fight fire with fire, huh?", the two flame wielding fighters start to battle. The trailer ends off with Ken being defeated (the same way he defeated Little Mac prior) and Incineroar posing for the cheering crowd. However, he stops posing to see that Villager, Bowser Jr., and King K. Rool are eager to engage in a match with him, with Incineroar growling in apathy.

Piranha Plant
While not necessarily an actual trailer, it was shown in-game that Luigi and some Yoshis are stunned, and Mario approaches forward to find its cause, only to find out a stationary Piranha Plant. Mario proceeds to attack it, but the Piranha Plant dodges it and counterattacks, then do a taunt ("Piranha Plant Pipes Up!").

Take Your Heart
The trailer starts with a noise screen, which eventually clears into a red screen displaying the Phantom Thieves' logo and slogan. Then the Joker gives a message "This is Joker. The mission is go." ("This is Joker. I've infiltrated the theatre." in the Game Awards 2018 version). Then Joker appears running to somewhere, while it is followed by a conversation among the Phantom Thieves:

Skull: “Wait a second! You mean... he went alone?” Panther: “What's so important that he'd run off by himself?” Mona: “There's only one thing that the Phantom Thieves of Heart specialize in.”
 * "Wait, seriously? You went alone to the Game Awards?" in the Game Awards 2018 version.
 * "But... it's so far away. Why is he there?" in the Game Awards 2018 version.

Fox: “He's there to steal a treasure. Have you already sent a calling card?”

Mona: “We're not the ones who sent a card this time. In fact, we've been invited. Invited to steal the greatest treasure of all!”

Then Joker proceeds to throw their calling card and it transforms into a blank white card which he catches it. It is later found to be a Smash invitation letter, to which, everyone caught in surprise. They later continue the conversation:

Panther: “WHAAAAAAT?!”

Skull: “Smash Bros.? Is this for real?!”

Then it shows monsters unmasked to reveal Personas which resemble various characters in Smash Bros., which are Mario, Donkey Kong, Samus, Link, Fox, Kirby, and Ness.

Mona: “We'll be going up against the best of the best! Can't wait to see our fearless leader show his stuff!”

The screen fades to black and Joker appears standing in the dark, removes his mask while exclaiming "Persona!" and releases his Persona, Arsene, appearing behind him. Arsene promises to himself, "I am thou, thou art I. Show the strength of thy will, and rage against all challengers!". The trailer ends with a text announcing that Joker from Persona 5 will appear in Challenger Pack #1.

Unlike all the trailers, this one only features just animation and no in-game footage, and it also lacks the new challenger banner.

The Masked Rebel
This trailer shows Joker catching the Smash Bros. invitation ("Joker Steals The Show!"). Just like the previous trailer, it also follows a conversation among the Phantom Thieves while gameplay for Joker can be seen:

Mona: "Joker, it's the moment you've been waiting for!"

Oracle: "So many legendary fighters! Awesome!"

Fox: "Uhh... Are you sure he can handle this?"

Queen: "I mean, he's got a knife and a gun... I'm sure he'll be fine."

Skull: "I don't know... they looked pretty tough!"

Mona: "Harness the power of the heart to summon a Persona! Unleash the rebellious spirit growing inside you!"

It is followed byJoker removing his mask while exclaiming "Persona!" and releases his Persona, Arsene, appearing behind him. The gameplay of Joker with Arsene is shown while the conversation continues:

Fox: "Ah... Arsene."

Skull: "Arsene? Can't he use a more powerful Persona?"

Panther: "What are you talking about? Arsene is awesome!"

Mona: "It's Joker's main Persona! As long as you hold on to your rebellious spirit, Arsene will give your attacks an extra punch!"

Noir: "Wow! He can use wings instead of his grappling hook!"

Mona: "If Joker is attacked while Arsene is around, he can counter-attack, with Tetrakarn and Makarakarn!"

Oracle: "A counter that's also a reflect?! Is that even allowed?!"

Then more gameplay is shown featuring the Mementos stage. The conversation continues:

Queen: "This is... Mementos?"

Noir: "The palace birthed from the hearts of the masses, right?

Mona: "Yes. And Mementos has a little secret"

Fox: "Isn't its entire existence a secret?"

Mona: "The base color changes, depending on the music!"

Most of the Phantom Thieves: "Wow!"

Skull: "Seriously? That's awesome!"

Panther: "I can't believe our eyes!"

Joker then proceeds to break a Smash Ball to perform his Final Smash, as the team prepares:

Skull: "Now's our chance! Let's help him out!"

Mona: "Witness the power of the Phantom Thieves!"

All Phantom Thieves: "GO!"

After Joker's final smash, his victory screen is shown. Mona comments further.

Mona: "Smash is looking cool, eh Joker?"

At the end of the trailer, Joker was shown stealing King K Rool's crown and Wario's bike.

Hero
Titled "Heroic Encounter", the trailer starts with a glimpse of Dharkon in a dark cloud-filled sky. Link is shown battling a false character of Marth. As Link is about to land a hit, a false character of Meta Knight stops him. Link retaliates with a throw of his boomerang, but they dodge it. Elsewhere in the distance, a horse is running across the burning forest fields towards the battlefield. As the false characters corner Link and prepare to land the final blow, a shadowed figure slashes them, launching them into the distance. Light then shines upon the shadowy figure, revealing it to be the Luminary ("The Hero draws near!"). Later, the Luminary is seen being launched into a pillar with a group of Slimes watching. The Luminary then finds himself surrounded by several false characters (Little Mac, Ridley, Zelda, Captain Falcon, Zero Suit Samus, Shulk, Bowser and Mewtwo can be seen in it). Then, they noticed a shining light in the distance, revealing Eight, Solo and Erdrick. The combined heroes then join forces to battle these false characters.

Banjo-Kazooie
Titled "Best Friends", the trailer itself is mostly the same as King K. Rool's trailer, but with a few differences. The trailer starts off with the villain montage from the aforementioned trailer, this time adding King K. Rool fighting the Kongs. We then see the Kongs and (unsuprisingly) King K. Rool napping together in Donkey Kong's treehouse. When a familiar puzzle piece bounces by, Donkey Kong wakes up and enters his battle stance, with Diddy Kong waking K. Rool up. The group then look outside the window to see what is afoot out there, accidentally destroying their window, where they soon see the silhouettes of a very familiar duo, who reveal themselves as Duck Hunt. With the Kongs and K. Rool shocked, the duo laugh at their misfortune, only for the same silhouettes to land right behind them, scaring them away. The silhouettes reveal themselves as Banjo and his sidekick, Kazooie ("Banjo-Kazooie are Raring to Go!"), with the Kongs cheering and K. Rool chomping his jaws in response. The trailer then transitions to King K. Rool falling off a cliff, making a crater on the ground in his shape before being trapped by a boulder (mimicking Gruntilda's defeat in the first Banjo-Kazooie game). Banjo thens bounces off the boulder and lands on the ground, almost losing his balance, who then does a victory pose, with the Kongs, Mario, Inkling, Duck Hunt, Fox, Pikachu, Pac-Man, King Dedede, Zelda, Captain Falcon, R.O.B., Bowser Jr., Villager, Wario, Ness, Kirby, Isabelle, Young Link, Bowser, Meta Knight, Sonic, Ice Climbers and Mega Man watching from the background, looking like they’re cheering, before the Banjo-Kazooie transition starts.

The trailer then ends with Banjo sneaking up a Giant Ivysaur sleeping next to some Pancakes. Banjo eats the food, accidentally waking up the Ivysaur, who chases Banjo as he runs away.
