On that note, here's a more general "villains" trailer that I thought up this morning:
Random blurb about my idea for a villain trailer:
Smash Bros. Fire Cross thing, trailer fades into Bowser being overwhelmed by the "hero team" of Mario, Samus, Link, DK, and Pikachu in the canyon area where Mega Man/Greninja was introduced, like the Mega Man trailer, it's nighttime like in the Mega Man trailer but rainclouds have moved in and partially hidden the moon and the stars. Bowser is fighting a losing battle in the rain that is going downhill fast and while trying to guard some of the attacks, Mario and Link find an opening, and both of them jump out from his blind spots (think of how Link/Mario did a jumping approach/attack on each other in the SSE cutscene where they first confront each other because one thinks the other KOed their princess), as Bowser was occupied with the other fighters. Link dives down (readying his classic thrusting finisher (Dair)) with Mario close behind him (readying a powerful punch akin to how he does his Fair). Bowser sees them but is unable to get out of the way, so he retreats into his shell to try to defend it. The simultaneous impact of Mario's Fist and Link's Master Sword on Bowser's shell crushes Bowser into the dirt, and a shallow crater is made as the impact sends out a powerful shockwave as a result (the impact also splays Bowser's limbs out of his shell, so he is laying spread eagle on his stomach, face down in the dirt). Mario and Link leap out from the shallow impact crater, Bowser (whom the camera has focused on for a brief moment), although struggling, cannot get back up (think of a person that is really hurt/drunk that keeps trying to stand up but falls back down to the ground; Bowser can't even push himself up with his arms at this point). Seeing this, Mario, Link, and the others (who have come and stood next to them) start doing a little celebration of seemingly another victory for the franchise "heroes." As they are celebrating, the rain still falling an average amount (not pouring, but a little less than a typical rainy day level of precipitation), the clouds begin to darken as lightning (in the clouds above them) flashes and the daunting boom of thunder (severe storm level volume) roars throughout their battleground.
The sudden crash of thunder and lightning comes with the rain going from average fall-rate into downpour levels. The heroes, who all flinched from the sudden, very loud thunder, look up to the clouds, miming wonder/confusion (also doing things like shielding themselves from the rain, DK covers his head with his hands, link holds his shield over his head, etc.) at the sudden apperance of such a severe storm. A few more lightning flashes are seen in the clouds as an almost blinding darkness falls onto the battlefield (the black clouds now completely covering the sky). Then, something lands near Bowser, and a lightning bolt suddenly falls onto the battlefield near Bowser and in front of the fighters, and with the brief light provided by the lightning, the fighters (and audience) can see the the silhouette of a large, ominous, humanoid figure wearing a cape who is standing over Bowser, Link gasps, and looks stunned as he stares the figure, before the battlefield fades into darkness once more and thunder booms again (The camera is from the perspective of Ganondorf, the audience can see his cape/ambiguous details about him without actually seeing his face and can see Link's reaction). As this thunderclap fades, the fighters can hear the sound of three more creatures landing close behind them. A lightning bolt flashes again, and DK, Pikachu, and Samus can see the silhouettes of a large, seemingly overweight humanoid crocodile, an alien-like humanoid creature with a tail, and a dragon-like creature low to the ground, his head covered slightly by a large pair of wings. The camera at this point is from the perspective of the newly appeared villains looking at DK, Pikachu, and Samus and the reactions they are having to recognizing the foes that just appeared; however, the audience can still see glimpses of the appearing villains, a glimpse at K. Rool's scales/cape, of Mewtwo's tail/feet, and Ridley's wings/tail all from behind them. The villains have fallen in a circle-like formation, surrounding the heroes and stepping closer. The camera changes to Bowser as he can be seen stirring, lifting his head slightly and forming a smile as he sees who all has just appeared. Then, a volley of lightning bolts falls to the ground suddenly, and it lights the area brightly for a good amount of time as Ganondorf walks up to Link (the camera now revealing his face), laughing; K. Rool approaches DK, also laughing ("K. Rool Joins the Battle!"); Mewtwo approaches Pikachu, his eyes glowing (like they do in the movie) and him either doing his sinister laugh (like his Melee taunt) or his actual Pokemon call ("Mewtwo Strikes Back!" him being the only veteran to get one because of his special circumstance); and finally, Ridley spreads his wings fully as he stands up, roaring loudly in Samus's face as his eyes glow in the darkness ("Ridley Joins The Battle"). The heroes recover from their shock slightly and prepare to fight as the villains lunge at them (Ganondorf takes on Link and Mario since Bowser is out of commision, btw). Cut to game footage of the villains dominating the heroes, going in order of the reveals in the cutscene (or reverse order), showing off a remade Ganondorf and Mewtwo and part of the movesets of K. Rool and Ridley. Music from each of their boss fights plays for each of them. After all the villains are shown, the trailer fades back into the battleground cutscene, the heroes locked firmly in battle with the villains (and the rainstorm continuing), the sound of a motorcycle engine can be heard as the camera focuses in on the engine of a bike with a W and a mustache on it as Wario comes riding in to the fight from the distance. Villains and heroes alike stop and notice who's coming, and panicking, all begin to run in the opposite direction, (Bowser now trying to limp away with them). The camera zooms back onto Wario, who noticing the panic, cracks a slight smile as he cranks the throttle on his bike to move even faster towards the fight (closing in very quickly now). The camera zooms back briefly on the fighters, some of the villains trying to trip or impede the heroes while they [the villains] make their escape, Ridley, for example, can be seen trying to take off into the skies (meanwhile Wario can be seen making it to the scene, the camera panning slowly outward from a bird's-eye view so the audience can see both Wario and all of the other fighters trying to run from him). Wario successfully closes the gap, but his bike's front tire hits one of the protuding edges from the impact crater and Wario's bike bucks him like a horse as he flies headlong through the air over the fighters (Ridley "shrieks" kind of like "oh no!" as Wario not only is in the range of the other fighters, but is also near/above him in the air now). Wario, although temporarily startled, notices his position and smiling, repositions his body mid-air to an upright position. The audience can see his backside begin to glow as he begins to chuckle. The trailer cuts to the Smash Bros Logo as the audience can hear (but not see) Wario's Fart Explosion go off violently. The trailer then fades out from the logo, as it does for all the other ones.
End of trailer.
It's heavy on characters, but I was envisioning this being the end all be all of newcomer videos so that Sakurai could "go out with a bang" so to speak.
