*Smash Ultimate Cross*
The trailer begins with a shot of a building belonging to Wario (either his house from WarioWare, or a giant skyscraper with his logo on it.)
Wario is seen entering his room while lugging giant bags of money, while laughing to himself. He approaches a wall covered with self portraits of all the characters currently in Smash, and he rips apart/throws darts at the portrait(s) of Lucas and/or Pokémon Trainer while laughing menacingly (implying that he stole money from them as an act of revenge for the events in Subspace Emissary.) Wario then starts thinking about all the things he can do with his new sum of money, and begins to laugh even more, to the point where he sounds like a lunatic.
We then pan back to outside the building, where we see everything surrounding the building to turn into a reddish hue in color, and starts to resemble a destroyed, ancient village, while the building itself starts to resemble a castle, like the one from Super Mario Land 2 or Wario World. Wario himself begins to change in appearance as well, as his eyes start to turn yellow, and his clothes now resemble
his appearance from WarioWare Gold. Shadowy creatures, either resembling generic blobs, or Fronks from WarioWare, begin to appear around Wario as well, but Wario doesn't notice any of this, and continues to laugh maniacally.
Suddenly, we see four shadowy figures zipping around the hallways of the building. Wario stops laughing as he hears this, and then wedged between some of the money in his bag, he notices what appears to be a giant red business card, which he pulls out. The card has a message, which Wario begins to read to himself, with the message being narrated by Xander Mobus.
"Wario, CEO of WarioWare Inc., and the money-devouring sinner of gluttony, you take advantage of those who work for you, as well those who get in your way, and exploit them all for the sole purpose of self-profit. We have decided to expose you of your crimes, and we will take your distorted desires without fail."
As the letter is being narrated, the shadowy figures continue to zip around the building, while the shadowy creatures/Fronks scattered throughout the building are destroyed, and Wario begins to appear nervous, but shrugs it off and throws the card away after Xander finishes with narrating the quoted part.
Suddenly, the doors to Wario's room slam open, with no one in sight, and all the Fronks in the room are destroyed. Wario's face turns into complete shock, and he finds himself surrounded by three silhouetted figures; one with a face resembling a skull, one with a face resembling a panther, and a short figure resembling a cat. Wario gets nervous and tries to run away, only to trip and be greeted with a silhouette with a very recognizable looking mask.
A red stripe flashes across the screen, and the four silhouettes being their all-out attack on Wario, with Xander Mobus narrating "Signed, the Phantom Thieves" during all of this. After that narration, Joker appears with his signature all-out attack pose, with the usual AOA background instead being replaced with:
JOKER STEALS THE SHOW
At this point, "Last Surprise" from Persona 5 starts playing, and the usual gameplay montage begins, with Skull, Panther, and/or Morgana narrating Joker's different skills as a fighter, while also quoting different compliments from Persona 5.
Different snippets they could use include:
-Joker evading Richter's long range attacks, and closing in with fast and powerful close ranged attacks with his knife.
-Joker beating up a taunting King K. Rool while in front of a bunch of bananas (represented with banana guns, the banana food item, and/or banana peel.)
-Joker and Bayonetta firing their guns at each other, with the projectiles of both cancelling out.
-Joker fighting against Marshadow and Ditto, the former referencing the reoccuring shadows from Persona, and the latter referencing the "I'll Face Myself" theme in Persona 4.
-Make a joke about Morgana's infamous "go to sleep" line with Peach's final smash.
-Showcase Joker's ability to use elemental abilities by using different Personas, which would be iconic demons from SMT, including Jack Frost and Pyro Jack. He would be using these attacks against different characters that use magic/PSI/elemental powers, such as Robin, Ness, and Pikachu.
-If Futaba Sakura/Oracle is an assist trophy, have a shot where Joker has a confused look while standing between her and Inkling Girl.
-Joker fighting Snake and Cloud, or Mario and Link on his stage, which would be Casino of Jealousy.
-If Casino of Jealousy has a stage boss, then it would likely be
-Final clip is Joker's final Smash, which would involve Joker using Down Shot on Link and/or Rex (if he's confirmed before Joker) and after landing, he performs the iconic all-out attack with Skull, Panther, and Morgana (in-game, make it so that Fox, Queen, and Noir can join Joker instead.)
SUPER SMASH BROS. ULTIMATE
Trailer ends with Wario's body (now back to his regular overalls/WarioWare clothes) appearing motionless, while Morgana and/or Ashley being taking the money he stole away.
