So I've already said that I'd love to see King K. Rool, Takamaru, Toad/Bowser Jr., Palutena, and a 3rd Party. So, uh, I've made a quick trailer...Don't take it seriously.
I imagine the trailer something like...
[collapse=Wall of text]The 4 iconic characters (Mario, Link, Pikachu, Kirby) somehow get extracted from their world and pop up in a battlefield. They start having a friendly fight when Bowser Jr. sees them in the distance. He thinks of a plan to crash the party. Newcomer: Bowser Jr. So Jr. hops into his Clown Car, and flies closer. However, King K. Rool is also in the distance and sees Mario & Co. Fighting. He decides that he wants to crash the party as well. Newcomer: King K. Rool. Rool comes closer and fires projectiles as well as Jr. The attacks both end up missing Mario & Co. and collide, causing Mario & Co to fall down because of the impact. Mario & Co. are confused when suddenly Rool and Jr. run up to each other angrily. They both blame each other for missing. Rool stops, however, and whispers in Jr.’s ear. Jr. nodes and laughs evilly as they both decide to join forces to attack Mario & Co.
Jr. quickly spits out fire balls. Mario can’t react fast enough, however, a blue figure quickly jumps out of a bush. He fires projectiles that intercept with the fire balls, protecting Mario & Co. Newcomer: Megaman. The duo villains both get upset, and they both fire a massive projectile. Megaman creates some sort of energy shield that reflects both projectiles in the same direction. Meanwhile...
Takamaru is randomly sitting peacefully on a hill nearby. He’s looking so handsome with his long hair blowing in the wind when, suddenly, he gets hit with the reflected projectile. Takamaru looks around for who caused the attack. He starts to walk down the path when he sees a figure coming his way, who turns out to be Roy. Roy’s just cleaning his sword, looking all sexy in his Awakening design when, suddenly, the other reflected projectile hits him in the head. The two glare at each other and then start to sword fight, as they mistake each other for causing the attacks. Newcomer: Takamaru. Returnee: Roy. However, they start to get closer to a steep part of the hill, eventually tumbling down. They roll right down to the base of the hill, right next to Mario & Co. The two swordsmen get up and continue battling. Mario’s all like, "Waah! We all have to work together to stop the party crashers!" Meanwhile...
Palutena is watching the battle from the Heavens. She decides that she wants to partake in the friendly brawl but thinks that Takamaru and Roy shouldn’t be fighting each other when there’s party crashers attacking. Newcomer: Palutena. She then comes down to the battlefield and intercepts Takamaru and Roy’s attack, pointing to the villains who were the real ones who hurt them. Both swordsmen apologize and Mario & Co. get ready to attack the villains. Rool and Jr. runs in and colloids with the good guys, and everyone dukes it out. You know how in cartoons, when people fight sometimes there’s a giant dust/smoke cloud covering them? And all you see are arms, legs, and some attacks that pop out of the dust? (Aka big ball of violence) Well the same thing happens during the fight, so it’s hard to see what’s going on.
Anyway, as the fight goes on, Takamaru is quickly pushed onto Palutena. He can’t hold it in and starts to nosebleed, blood squirting right out of the cloud. King K. Rool’s tail somehow gets stuck in Megaman’s canon arm, while Palutena’s hair gets caught in the Clown Car’s propeller. However, Wario is hiding in a bush near them all along. He wants to crash the party and is all like, "Eh eh eeeh!" He jumps out and faces his back to them, sticking out his bottom. He then does his fart attack but a massive pillar of gas shoots out from his bottom and fires straight into the cloud. Roy does some sort of fire attack, however, the gas hits the fire causing a gigantic explosion.
-alternately, replace the gas with something explosive- The damage is huge, causing the world to blow up. After a couple of seconds, Mario respawns, and is like
Then all goes black. You think it's over when an evil laugh is heard..."Muwhahahaha!"
